INTRODUCTION

In this annual report, except where the context otherwise requires and for purposes of this annual report only:

(cid:129) “we,” “us,” “our company,” “our,” and “Baidu” refer to Baidu, Inc., its subsidiaries, and, in the context of
describing our operations and consolidated financial information, also include Beijing Baidu Netcom
Science Technology Co., Ltd., Beijing Perusal Technology Co., Ltd. , Beijing BaiduPay Science and
Technology Co., Ltd., and Baidu HR Consulting (Shanghai) Co., Ltd., all of which are our consolidated
affiliated entities in China;

(cid:129) “user traffic” or “traffic” refers generally to page views and the reach of a website. When used in the context
of Alexa.com website traffic rankings, “user traffic” refers to a combined measure of the “page views” and
the “reach” of a website averaged over a specified period of time, according to Alexa.com. Page views
measure the number of web pages viewed by Internet users over a specified period of time except that
multiple page views of the same page viewed by the same user on the same day are counted only once; reach
measures the number of Internet users and is typically expressed as the percentage of all Internet users who
visit a given website;

(cid:129) “China” or “PRC” refers to the People’s Republic of China, and solely for the purpose of this annual report,

excluding Taiwan, Hong Kong and Macau;

(cid:129) “shares” or “ordinary shares” refers to our ordinary shares, which include both Class A ordinary shares and

Class B ordinary shares;

(cid:129) “ADSs” refers to our American depositary shares. On May 12, 2010, we effected a change of the ADS to
Class A ordinary share ratio from 1 ADS representing 1 Class A ordinary share to 10 ADSs representing 1
Class A ordinary share. The ratio change has the same effect as a 10-for-1 ADS split;

(cid:129) “U.S. GAAP” refers to generally accepted accounting principles in the United States;

(cid:129) all references to “RMB” or “Renminbi” are to the legal currency of China and all references to “$,” “dollars,”

“US$” and “U.S. dollars” are to the legal currency of the United States; and

(cid:129) all discrepancies in any table between the amounts identified as total amounts and the sum of the amounts

listed therein are due to rounding.

FORWARD-LOOKING INFORMATION

This annual report on Form 20-F contains statements of a forward-looking nature. These statements are made
under the “safe harbor” provisions of the U.S. Private Securities Litigation Reform Act of 1995. You can identify
these forward-looking statements by words or phrases such as “may,” “will,” “expect,” “anticipate,” “aim,”
“estimate,” “intend,” “plan,” “believe,” “is/are likely to” or other similar expressions. We have based these forward-
looking statements largely on our current expectations and projections about future events and financial trends that
we believe may affect our financial condition, results of operations, business strategy and financial needs. These
forward-looking statements include, but are not limited to:

(cid:129) our growth strategies;

(cid:129) our future business development, results of operations and financial condition;

(cid:129) our ability to attract and retain users and customers;

(cid:129) our ability to successfully expand into and generate profits from our new Internet businesses;

(cid:129) our ability to retain key personnel and attract new talents;

(cid:129) the outcome of ongoing or any future litigation, including those relating to copyright or other intellectual

property rights;

(cid:129) competition in the Internet search market;

2

(cid:129) the expected growth of the Internet search market and the number of Internet and broadband users in China;

(cid:129) PRC governmental regulations and policies relating to the Internet and Internet search providers; and

(cid:129) development of PRC tax law reforms that may have uncertain implications on high and new technology

companies.

We would like to caution you not to place undue reliance on forward-looking statements and you should read
these statements in conjunction with the risk factors disclosed in “Item 3.D. Key Information — Risk Factors.”
Those risks are not exhaustive. We operate in a rapidly evolving environment. New risk factors emerge from time to
time and it is impossible for our management to predict all risk factors, nor can we assess the impact of all factors on
our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially
from those contained in any forward-looking statement. We do not undertake any obligation to update or revise the
forward-looking statements except as required under applicable law.

(1) As holders of Class A and Class B ordinary shares have the same dividend right and the same participation right
in our undistributed earnings, the basic and diluted net income per share of Class A and Class B ordinary shares
are the same for all the periods presented during which there were two classes of ordinary shares. The weighted
average number of ordinary shares represents the sum of the weighted average number of Class A and Class B
ordinary shares. Please see “Earnings per Share” under Note 14 to our audited consolidated financial statements
included in this annual report for additional information regarding the computation of the per share amount and
the weighted average numbers of Class A and Class B ordinary shares.

Exchange Rate Information

Our business is primarily conducted in China and almost all of our revenues are denominated in RMB.
However, periodic reports made to shareholders will include current period amounts translated into U.S. dollars
using the then current exchange rates, for the convenience of the readers. The conversion of RMB into U.S. dollars
in this annual report is based on the noon buying rate in New York City for cable transfers in RMB as certified for
customs purposes by the Federal Reserve Board. Unless otherwise noted, all translations from RMB to U.S. dollars
and from U.S. dollars to RMB in this annual report were made at a rate of RMB6.6000 to US$1.00, the noon buying
rate in effect as of December 30, 2010. We make no representation that any RMB or U.S. dollar amounts could have
been, or could be, converted into U.S. dollars or RMB, as the case may be, at any particular rate, or at all. The PRC
government imposes control over its foreign currency reserves in part through direct regulation of the conversion of

Risks Related to Our Business

If we fail to retain existing customers or attract new customers for our online marketing services, our
business, results of operations and growth prospects could be seriously harmed.

We generate almost all of our revenues from online marketing services, a substantial majority of which are
derived from our pay-for-performance, or P4P, services. Our online marketing customers will not continue to do
business with us if their investment does not generate sales leads and ultimately consumers, or if we do not deliver
their web pages in an appropriate and effective manner. Our P4P customers may discontinue their business with us
at any time and for any reason as they are not subject to fixed-term contracts. In April 2009, we officially launched
Online Marketing Professional Edition, which we also refer to as Phoenix Nest, our new auction-based online
marketing system designed to improve relevance in paid search and increase value for customers. In December
2009, we completed the switch from our previous online marketing system, which we refer to as the Online
Marketing Classic Edition, to Phoenix Nest. If Phoenix Nest is perceived to be a less effective marketing tool than
the Online Marketing Classic Edition, we may lose existing customers or encounter difficulty attracting new
customers. In addition, we have in the past removed, and may in the future again remove, questionable paid search
listings of some customers to ensure the quality and reliability of our search results. Such removal, whether
temporary or permanent, may cause the affected customers to discontinue their business with us. Moreover, third
parties may develop and use certain technologies to block the display of our customers’ advertisements and other
marketing products on our Baidu.com website, which may in turn cause us to lose customers and adversely affect
our operating results. Furthermore, we adjust prices for our online marketing services from time to time. We may
lose customers who decide not to pay our increased prices. Failure to retain our existing customers or attract new
customers for our online marketing services could seriously harm our business, results of operations and growth
prospects.

If online marketing does not further grow in China, our ability to increase revenue and profitability could
be materially and adversely affected.

The use of the Internet as a marketing channel is at a developing stage in China. Internet penetration rate in
China is relatively low as compared to that in most developed countries. Many of our current and potential
customers have limited experience with the Internet as a marketing channel, and historically have not devoted a
significant portion of their marketing budgets to online marketing and promotion. As a result, they may not consider
the Internet an effective channel to promote their products and services as compared to traditional print and
broadcast media. Our ability to increase revenue and profitability from online marketing may be adversely impacted
by a number of factors, many of which are beyond our control, including:

(cid:129) difficulties associated with developing a larger user base with demographic characteristics attractive to

customers;

(cid:129) increased competition and potential downward pressure on online marketing prices;

(cid:129) higher customer acquisition costs due in part to the limited experience of small to medium-sized enterprises,

or SMEs, with the Internet as a marketing channel;

(cid:129) failure to develop an independent and reliable means of verifying online traffic;

(cid:129) ineffectiveness of our online marketing delivery, tracking and reporting systems; and

(cid:129) decreased use of Internet or online marketing in China.

Our business depends on a strong brand, and if we are not able to maintain and enhance our brand, our
business and operating results may be harmed.

We believe that our brand “Baidu” has contributed significantly to the success of our business. We also believe
that maintaining and enhancing the “Baidu” brand is critical to increasing the numbers of our users, customers and
Baidu Union members. Maintaining and enhancing our brand will depend largely on our ability to remain as the
Internet search leader in China, which may become more expensive and challenging.

Historically, we developed our user base primarily by word-of-mouth and incurred limited brand promotion
expenses. Our initial public offering in 2005 and positive media coverage in subsequent years have significantly
enhanced our brand recognition. We have also conducted marketing and brand promotion activities in recent years,
but we cannot assure you that these activities will achieve the brand promotion effect expected by us. If we fail to
maintain and further promote the “Baidu” brand, or if we incur excessive expenses in this effort, our business and
results of operations may be materially and adversely affected. In addition, any negative publicity about our
company, our products and services, our employees, our business practices, or our search results or websites to
which our search results link, regardless of its veracity, could harm our brand image and in turn adversely affect our
business and operating results.

We face significant competition and may suffer from a loss of users and customers as a result.

We face significant competition in almost every aspect of our business, particularly from other companies that
seek to provide Internet search services to users and provide online marketing services to customers. In the Chinese
Internet search market, our main competitors include U.S.-based Internet search providers providing Chinese
language Internet search services, such as Google and Microsoft, and China-based Internet companies, such as
Netease, Sohu, Tencent and Alibaba. We compete with these entities for both users and customers on the basis of
user traffic, quality (relevance) and quantity (index size) of the search results, availability and ease of use of
products and services, the number of customers, distribution channels and the number of associated third-party
websites. In addition, our e-commerce services face competition from the existing leading e-commerce companies
in China.

Some of our competitors have significantly greater financial resources, longer operating histories and more
experience in attracting and retaining users and managing customers than we do. They may use their experience and
resources to compete with us in a variety of ways, including by competing more heavily for users, customers,
distributors, strategic partners and networks of third-party websites, investing more heavily in research and
development and making acquisitions. If any of our competitors provides comparable or better Chinese language
search experience, our user traffic could decline significantly. Any such decline in traffic could weaken our brand
and result in loss of customers, which would have a material adverse effect on our results of operations.

We also face competition from other types of advertising media, such as newspapers, magazines, yellow pages,
billboards and other forms of outdoor media, television and radio. Large companies in China generally allocate, and
may continue to allocate, most of their marketing budgets to traditional advertising media and only a small portion
of their budgets to online marketing and other forms of advertising media. If these companies do not devote a larger
portion of their marketing budgets to online marketing services provided by us, or if our existing customers reduce
the amount they spend on online marketing, our results of operations and growth prospects could be adversely
affected.

If our expansions into new Internet businesses are not successful, our future results of operations and
growth prospects may be materially and adversely affected.

As part of our growth strategy, we enter into new Internet businesses from time to time by leveraging our large
Internet search user base to generate additional revenue streams. Expansions into new businesses may present
operating and marketing challenges that are different from those that we currently encounter. For each new business
we enter into, we face competition from existing leading players in that business. If we cannot successfully address
the new challenges and compete effectively against the existing leading players in the new businesses, we may not
be able to develop a sufficiently large customer and user base, recover costs incurred for developing and marketing

8

new businesses, and eventually achieve profitability from these businesses, and our future results of operations and
growth prospects may be materially and adversely affected.

If we fail to continue to innovate and provide products and services to attract and retain users, we may
not be able to generate sufficient user traffic levels to remain competitive.

Our success depends on providing products and services to attract users and enable users to have a high-quality
Internet experience. In order to attract and retain users and compete against our competitors, we must continue to
invest significant resources in research and development to enhance our Internet search technology, improve our
existing products and services and introduce additional high-quality products and services. If we are unable to
anticipate user preferences or industry changes, or if we are unable to modify our products and services on a timely
basis, we may lose users. Our operating results may also suffer if our innovations do not respond to the needs of our
users, are not appropriately timed with market opportunities or are not effectively brought to market. As search
technology continues to develop, our competitors may be able to offer search results that are, or that are perceived to
be, substantially similar to or better than those generated by our search services. This may force us to expend
significant resources in order to remain competitive.

If we fail to keep up with rapid changes in technologies and user behavior, our future success may be
adversely affected.

Our future success will depend on our ability to respond to rapidly changing technologies, adapt our services to
evolving industry standards and improve the performance and reliability of our services. Our failure to adapt to such
changes could harm our business. In addition, changes in user behavior resulting from technological developments
may also adversely affect us. For example, the number of people accessing the Internet through devices other than
personal computers, including mobile phones and other hand-held devices, has increased in recent years, and we
expect this trend to continue while 3G and more advanced mobile communications technologies are broadly
implemented. If we fail to develop products and technologies that are compatible with all mobile devices, or if the
products and services we develop are not widely accepted and used by users of various mobile devices, we may not
be able to penetrate the mobile markets. In addition, the widespread adoption of new Internet, networking or
telecommunications technologies or other technological changes could require substantial expenditures to modify
or integrate our products, services or infrastructure. If we fail to keep up with rapid technological changes to remain
competitive, our future success may be adversely affected.

Interruption or failure of our own information technology and communications systems or those of third-
party service providers we rely upon could impair our ability to provide our products and services, which
could damage our reputation and harm our operating results.

Our ability to provide our products and services depends on the continuing operation of our information
technology and communications systems. Any damage to or failure of our systems could interrupt our service.
Service interruptions could reduce our revenues and profits and damage our brand if our system is perceived to be
unreliable. Our systems are vulnerable to damage or interruption as a result of terrorist attacks, wars, earthquakes,
floods, fires, power loss, telecommunications failures, undetected errors or “bugs” in our software, computer
viruses, interruptions in access to our websites through the use of “denial of service” or similar attacks, hacking or
other attempts to harm our systems, and similar events. Some of our systems are not fully redundant, and our
disaster recovery planning does not account for all possible scenarios.

Our servers, which are hosted at third-party Internet data centers, are vulnerable to break-ins, sabotage and
vandalism. The occurrence of a natural disaster or a closure of an Internet data center by a third-party provider
without adequate notice could result in lengthy service interruptions. In addition, our domain names are resolved
into Internet protocol (IP) addresses by systems of third-party domain name registrars and registries. Any
interruptions or failures of those service providers’ systems, which are beyond our control, could significantly
disrupt our own services. In January 2010, the name server records of our main domain name, Baidu.com, which are
recorded on the systems of a domain name registrar in the U.S., were modified by hackers who gained access to such
records. As a result, our Internet search services were interrupted for approximately five hours.

9

If we experience frequent or persistent system failures on our websites, whether due to interruptions and
failures of our own information technology and communications systems or those of third-party service providers
we rely upon, our reputation and brand could be severely harmed. The steps we take to increase the reliability and
redundancy of our systems are expensive, may reduce our operating margin and may not be successful in reducing
the frequency or duration of service interruptions.

We may not be able to manage our expanding operations effectively.

We have significantly expanded our operations in recent years. We expect this expansion trend to continue as
we grow our user and customer base and explore new opportunities. To manage the further expansion of our
business and growth of our operations and personnel, we need to continuously improve our operational and
financial systems, procedures and controls, and expand, train, manage and maintain good relations with our growing
employee base. We have experienced labor disputes in the past. Although these disputes were resolved promptly, we
cannot assure you that there won’t be any new labor dispute in the future. In addition, we must maintain and expand
our relationships with other websites, Internet companies and other third parties. Our current and future personnel,
systems, procedures and controls may not be adequate to support our expanding operations.

We may face intellectual property infringement claims and other related claims that could be time-con-
suming and costly to defend and may result in a material adverse impact over our operations.

Internet, technology and media companies are frequently involved in litigation based on allegations of
infringement of intellectual property rights, unfair competition, invasion of privacy, defamation and other violations
of other parties’ rights. The validity, enforceability and scope of protection of intellectual property in Internet-
related industries, particularly in China, are uncertain and still evolving. As we face increasing competition and as
litigation becomes more common in China in resolving commercial disputes, we face a higher risk of being the
subject of intellectual property infringement claims. We may be also subject to administrative actions brought by
the PRC State Copyright Bureau, and in the most severe scenario criminal prosecution, for alleged copyright
infringement, and as a result may be subject to fines and other penalties and be required to discontinue infringing
activities. Furthermore, as we expand our operations outside China, we may be subject to claims brought again us in
jurisdictions outside China.

Our products and services link to materials in which third parties may claim ownership of trademarks,
copyrights or other rights. For example, we provide search engine facilities capable of finding and accessing links to
downloadable audio, video, image and other multimedia files and other items hosted on third-party websites,
including search functions that enable our users to search for files in various ways, such as by artist, title, or via lists
of most-searched-for titles and artists. Some of these contents found using our search engine facilities may be
protected by copyright or other intellectual property rights. Like many other Internet websites, we host on our
websites certain song lyrics which may be protected by copyright. As a result, we may be subject to copyright or
trademark infringement and other related claims from time to time, in China and internationally.

In China, uncertainties still exist with respect to the legal standards as well as the judicial interpretation of such
standards for determining liabilities of Internet search providers for providing links to contents on third-party
websites that infringe others’ copyrights. In December 2007, the High People’s Court of Beijing upheld a lower
court’s ruling in our favor in a case originally filed against us in 2005 by seven music record companies alleging that
our MP3 search services had infringed their copyrights. The court ruled that our service, which only provides links
to online music hosted on third parties’ websites, does not constitute infringement. In the same month, however, the
High People’s Court of Beijing upheld the decision by another lower court in favor of the record companies in a suit
originally filed by 11 record companies against Yahoo! China, one of our competitors, in July 2006. In the Yahoo!
China case, the court held that Yahoo! China was negligent in failing to remove all links to the infringing content
after receiving notice from copyright holders, including those links that it “should have known” to have infringing
content.

Although prior court rulings in China have only limited precedential value, the ruling of the High People’s
Court of Beijing in the Yahoo! China case seems to suggest that the courts in future cases may place the burden on
Internet search providers to remove not only links that have been specifically mentioned in notices of infringement

10

from right holders, but also links they “should have known” to contain infringing content. This interpretation was
also adopted in the guidance on Internet related copyright infringement litigations issued by the High People’s
Court of Beijing in May 2010. Such an interpretation of the applicable law could subject Internet search providers
like us to significant administrative burdens and litigation risks.

We conduct our business operations outside the United States. However, we may be subject to U.S. copyright
laws, including the legal standards for determining indirect liability for copyright infringement, by virtue of our
listing on the NASDAQ, the ownership of our ADSs or ordinary shares by U.S. residents, the extraterritorial
application of U.S. law by U.S. courts or otherwise. In June 2009, a plaintiff filed a copyright infringement lawsuit
against us in the U.S. District Court for the Southern District of New York. In December 2009, the court granted our
motion to dismiss the complaint on the grounds of insufficient service of process and lack of personal jurisdiction.
The plaintiff did not appeal the trial court’s ruling. Despite the above ruling in our favor, we cannot assure you that
we will not be subject to lawsuits or other proceedings in the U.S. or elsewhere in the future.

Intellectual property litigation is expensive and time-consuming and could divert resources and management
attention from the operations of our business. We are currently named as a defendant in a number of copyright
infringement suits in connection with our MP3 and other search services. See “Item 8.A. Financial Information —
Consolidated Statements and Other Financial Information — Legal Proceedings.” If there is a successful claim of
infringement, we may be required to discontinue the infringing activities, pay substantial fines and damages and/or
enter into royalty or license agreements that may not be available on commercially acceptable terms, if at all. Our
failure to obtain a license of the rights on a timely basis could harm our business. Any intellectual property litigation
and/or any negative publicity by third parties alleging our intellectual property infringement could have a material
adverse effect on our business, reputation, financial condition or results of operations. To address the risks relating
to intellectual property infringement, we may have to substantially modify, limit or terminate some of our search
services. Any such change could materially affect user experience and in turn have a material adverse impact on our
business.

We have been and may again be subject to claims based on the content found on our websites or the
results in our paid search listings.

In addition to the content developed by ourselves and posted on our websites, our users are free to post
information on Baidu Post Bar, Baidu Knows, Baidu Encyclopedia and other sections of our websites, and our P4P
customers may create text-based descriptions and other phrases to be used as text or keywords in our search listings.
We have been and may continue to be subject to claims for defamation, negligence or other legal theories based on
the content found on our websites. Claims for defamation, negligence or other legal theories based on the content
found on our websites, with or without merit, may result in diversion of management attention and financial
resources and negative publicity on our brand and reputation. See “Item 8A. Financial Information — Consolidated
Statements and Other Financial Information — Legal Proceedings.” Furthermore, if the content posted on our
websites contains information that government authorities find objectionable, our websites may be shut down and
we may be subject to other penalties. See “— Risks Related to Doing Business in China — Regulation and
censorship of information disseminated over the Internet in China may adversely affect our business and subject us
to liability for information displayed on or linked to our websites.”

Under PRC advertising laws and regulations, we, as an online advertising service provider, are obligated to
monitor the advertising content posted on our websites to ensure that such content is fair and accurate and in
compliance with applicable law. In addition, where a special government review is required for specific categories
of advertisements before posting, we are obligated to confirm that such review has been performed and approval has
been obtained. See “Item 4.B. Information on the Company — Business Overview — Regulation — Regulations
on Advertisements.” Our reputation could be hurt and our results of operations could be adversely affected due to
penalties imposed on us if advertisements shown on our websites are provided to us by our advertising clients in
violation of relevant PRC advertising laws and regulations, or if the supporting documentation and government
approvals provided to us by our advertising clients in connection with such advertising content are not complete.
Our P4P services are not subject to PRC advertising laws and regulations because PRC laws and regulations and
administrative authorities currently do not classify P4P services as a form of online advertising. However, if P4P
services are classified as a form of online advertising in the future, we would be obligated to examine the content of

11

our P4P customers’ listings on our websites, as required by PRC advertising laws, and such examination could be
very burdensome.

Moreover, we have been and in the future may again be subject to claims or negative publicity based on the
results in our paid search listings. Claims have been filed against us after we allowed certain customers to purchase
keywords containing trademarks, trade names or brand names owned by others and displayed links to such
customers’ websites in our paid search listings. While we maintain a database of certain well-known trademarks and
would not allow a customer to submit a keyword containing the well-known trademarks that we know are owned by
others, it is not possible for us to completely prevent our customers from bidding on keywords that contain
trademarks, trade names or brand names owned by others. Claims and negative publicity based on the results in our
paid search listings, regardless of their merit, may divert management attention, severely disrupt our operations,
adversely affect our results of operations and harm our reputation.

We may be subject to patent infringement claims with respect to our P4P platform.

Our technologies and business methods, including those relating to our P4P platform, may be subject to third-
party claims or rights that limit or prevent their use. In June 2005, we applied for a patent in China for our P4P
platform, but our application was rejected on the ground that it is not patentable. Certain U.S.-based companies,
including Overture Services Inc., have been granted patents in the United States relating to P4P platforms and
similar business methods and related technologies. While we believe that we are not subject to U.S. patent laws
since we conduct our business operations outside of the United States, we cannot assure you that U.S. patent laws
would not be applicable to our business operations, or that holders of patents relating to a P4P platform would not
seek to enforce such patents against us in the United States or China.

In addition, many parties are actively developing and seeking protection for Internet-related technologies,
including seeking patent protection. There may be patents issued or pending that are held by others that relate to
certain aspects of our technologies, products, business methods or services. For example, we are aware that a patent
has been issued in China relating to a method used by a database search system that determines the optimal bidding
price for keywords based on an advertiser’s desired place in a search listing. Based on our own analysis and the
analysis conducted by a third-party intellectual property agency, we do not believe that our P4P platform infringes
this patent because, among other things, our system ranks customers’ links according to a comprehensive ranking
index calculated based on both the quality factor of a keyword and the price bid on the keyword. However, the
application and interpretation of Chinese patent laws and the procedures and standards for granting patents in China
are still evolving and involve uncertainty. We cannot assure you that PRC courts or regulatory authorities would
agree with the above analysis. Any patent infringement claims, regardless of their merits, could be time-consuming
and costly to us. If we were sued for patent infringement claims with respect to our P4P platform and were found to
infringe such patents and were not able to adopt non-infringing technologies, we may be severely limited in our
ability to operate our P4P platform, which would have a material adverse effect on our results of operations and
prospects.

Our business may be adversely affected by third-party software applications or practices that interfere
with our receipt of information from, or provision of information to, our users, which may impair our
users’ experience.

Our business may be adversely affected by third-party malicious or unintentional software applications that
make changes to our users’ computers and interfere with our products and services. These software applications
may change our users’ Internet experience by hijacking queries to our websites, altering or replacing our search
results, or otherwise interfering with our ability to connect with our users. The interference often occurs without
disclosure to or consent from users, resulting in a negative experience that users may associate with our websites.
These software applications may be difficult or impossible to remove or disable, may reinstall themselves and may
circumvent other applications’ efforts to block or remove them. In addition, our business may be adversely affected
by the practices of third-party website owners which interfere with our ability to crawl and index their web pages.
The ability to provide a superior user experience is critical to our success. If we are unable to successfully combat
third-party software applications that interfere with our products and services, our reputation may be harmed. If a

12

significant number of website owners prevent us from indexing and including their web pages in our search results,
the quality of our search results may be impaired.

Our success depends on the continuing and collaborative efforts of our management team and other key
personnel, and our business may be harmed if we lose their services.

Our future success depends heavily upon the continuing services of our management team, in particular our
chairman and chief executive officer, Robin Yanhong Li. If one or more of our executives or other key personnel are
unable or unwilling to continue in their present positions, we may not be able to replace them easily or at all, and our
business may be disrupted and our financial condition and results of operations may be materially and adversely
affected. Our former chief operating officer and chief technology officer resigned for personal reasons in January
2010, and we have not appointed new chief operating officer or chief technology officer. Competition for
management and key personnel is intense, the pool of qualified candidates is limited, and we may not be able
to retain the services of our executives or key personnel, or attract and retain experienced executives or key
personnel in the future.

If any of our executives or other key personnel joins a competitor or forms a competing company, we may lose
customers, distributors, know-how and key personnel. Each of our executive officers and key employees has entered
into an employment agreement with us, containing confidentiality and non-competition provisions. If any disputes
arise between any of our executives or key personnel and us, we cannot assure you the extent to which any of these
agreements may be enforced.

We rely on highly skilled personnel. If we are unable to retain or motivate them or hire additional quali-
fied personnel, we may not be able to grow effectively.

Our performance and future success depend on the talents and efforts of highly skilled individuals. We will
need to continue to identify, hire, develop, motivate and retain highly skilled personnel for all areas of our
organization. Competition in the Internet industry for qualified employees is intense. Our continued ability to
compete effectively depends on our ability to attract new employees and to retain and motivate our existing
employees.

As competition in the Internet industry intensifies, it may be more difficult for us to hire, motivate and retain
highly skilled personnel. If we do not succeed in attracting additional highly skilled personnel or retaining or
motivating our existing personnel, we may be unable to grow effectively.

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 operating
results. Accordingly, you should consider our future prospects in light of the risks and uncertainties experienced by
companies in evolving industries. Some of these risks and uncertainties relate to our ability to:

(cid:129) maintain our leading position in the Chinese language Internet search market;

(cid:129) offer new, innovative products and services to attract and retain a larger user base;

(cid:129) attract additional customers and increase spending per customer;

(cid:129) further enhance our brand;

(cid:129) maintain the quality of our products and services and continue to develop user and customer loyalty;

(cid:129) respond to competitive market conditions;

(cid:129) respond to changes in the regulatory environment;

(cid:129) manage legal risks, including those associated with intellectual property rights;

(cid:129) maintain effective control of our costs and expenses;

13

(cid:129) attract, retain and motivate qualified personnel and maintain good relations with a young and growing work

force;

(cid:129) build profitable operations in new markets such as the Japanese Internet search market; and

(cid:129) upgrade our technology to support increased traffic and expanded services.

If we are unsuccessful in addressing any of these risks and uncertainties, our business may be materially and

adversely affected.

Our historical growth rate may not be indicative of our future growth rate.

We have experienced substantial growth in recent years. Our total revenues and net income grew at a
compound annual growth rate, or CAGR, of 75.3% and 84.9%, respectively, from 2006 to 2010. Our growth was
driven in part by the growth in China’s Internet and online marketing industries, which may not be indicative of
future growth or be sustainable. Our past growth rate may not be indicative of our future growth rate.

Our operating results may fluctuate, which makes our results difficult to predict and could cause our
results to fall short of expectations.

Our operating results may fluctuate as a result of a number of factors, many of which are outside of our control.
For these reasons, comparing our operating results on a period-to-period basis may not be meaningful, and you
should not rely on our past results as an indication of our future performance. Our quarterly and annual revenues and
costs and expenses as a percentage of our revenues may be significantly different from our historical or projected
figures. Our operating results in future quarters may fall below expectations. Any of these events could cause the
price of our ADSs to fall. Any of the risk factors listed in this “Risk Factors” section, and in particular the following
risk factors, could cause our operating results to fluctuate from quarter to quarter:

(cid:129) general economic conditions in China and economic conditions specific to the Internet, Internet search and

online marketing;

(cid:129) our ability to continue to attract users to our websites;

(cid:129) our ability to attract additional customers and increase spending per customer;

(cid:129) the announcement or introduction of new or enhanced products and services by us or our competitors;

(cid:129) the amount and timing of operating costs and capital expenditures related to the maintenance and expansion

of our businesses, operations and infrastructure;

(cid:129) the results of our acquisitions of, or investments in, other businesses or assets;

(cid:129) PRC regulations or government actions pertaining to activities on the Internet, including music, video, news,
gambling, online games and other forms of entertainment, or otherwise affecting our online marketing
customers;

(cid:129) unforeseen events, such as negative publicity arising from reports by influential media outlets and other

sources and labor disputes; and

(cid:129) geopolitical events, natural disasters or epidemics.

Because of the rapid growth of our business, our historical operating results may not be useful to you in
predicting our future operating results. Our user traffic tends to be seasonal. For example, we generally experience
less user traffic during public holidays and other special event periods in China. In addition, advertising and other
marketing spending in China has historically been cyclical, reflecting overall economic conditions as well as
budgeting and buying patterns. Our rapid growth has lessened the impact of the cyclicality and seasonality of our
business. As we continue to grow, we expect that the cyclicality and seasonality in our business may cause our
operating results to fluctuate.

A severe and prolonged global economic recession and the corresponding slowdown in the Chinese econ-
omy may adversely affect our business, results of operations and financial condition.

The world economy is still recovering from the recent global financial crisis. While the Chinese economy has
recovered more quickly than some other major economies, it still faces challenges. The long-term effects of the
stimulus plans and other measures implemented by the Chinese government since 2008 remain to be seen. Since we
derive most of our revenues from online marketing customers in China, any prolonged slowdown in the Chinese
economy may have a negative impact on our business, operating results and financial condition in a number of
ways. For example, our customers may reduce or delay spending with us, while we may have difficulty expanding
our customer base fast enough, or at all, to offset the impact of decreased spending by our existing customers. In
addition, to the extent we offer credit to any customer and such customer experiences financial difficulties due to the
economic slowdown, we could have difficulty collecting payment from such customer.

We may not be able to prevent others from unauthorized use of our intellectual property, which could
harm our business and competitive position.

We rely on a combination of copyright, trademark and trade secret laws, as well as nondisclosure agreements
and other methods to protect our intellectual property rights. The protection of intellectual property rights in China
may not be as effective as those in the United States or other countries. The steps we have taken may be inadequate
to prevent the misappropriation of our technology. Reverse engineering, unauthorized copying or other misap-
propriation of our technologies could enable third parties to benefit from our technologies without paying us.
Moreover, unauthorized use of our technology could enable our competitors to offer products and services that are
comparable to or better than ours, which could harm our business and competitive position. From time to time, we
may have to enforce our intellectual property rights through litigation. Such litigation may result in substantial costs
and diversion of resources and management attention.

Because we rely to a large extent on distributors in providing our P4P services, our failure to retain key
distributors or attract additional distributors could materially and adversely affect our business. Moreover,
there is no assurance that our direct sales model in some key geographic markets will continue to be
successful.

Online marketing is at an early stage of development in China and is not as widely accepted by or available to
businesses in China as in the United States. As a result, we rely to a large extent on a nationwide distribution
network of third-party distributors for our sales to, and collection of payment from, our P4P customers. If our
distributors do not provide quality services to our P4P customers or otherwise breach their contracts with our P4P
customers, we may lose customers and our results of operations may be materially and adversely affected. We do
not have long-term agreements with any of our distributors and cannot assure you that we will continue to maintain
favorable relationships with them. If we fail to retain our key distributors or attract additional distributors on terms
that are commercially reasonable, our business and results of operations could be materially and adversely affected.

We have transitioned to using our direct sales force to serve our P4P customers in some key geographic
markets. There is no assurance that our direct sales model in those markets will continue to be successful. If we fail
to maintain an adequate direct sales force, retain existing customers and continue to attract new customers in those
markets, our business, results of operations and prospects could be materially and adversely affected.

We rely on our Baidu Union members for a significant portion of our revenues. If we fail to retain exist-
ing Baidu Union members or attract additional members, our revenue growth and profitability may be
adversely affected.

We pay our Baidu Union members a portion of our revenues generated from click-throughs by users of our
Baidu Union members’ property. We consider our Baidu Union critical to the future growth of our revenues. Some
of our Baidu Union members, however, may compete with us in one or more areas of our business. Therefore, they
may decide in the future to terminate their relationships with us. If our Baidu Union members decide to use a
competitor’s or their own Internet search services, our user traffic may decline, which may adversely affect our
revenues. If we fail to attract additional Baidu Union members, our revenue growth may be adversely affected. In

15

addition, if we have to share a larger portion of our revenues to retain existing Baidu Union members or attract
additional members, our profitability may be adversely affected.

Our strategy of acquiring complementary businesses, assets and technologies may fail.

As part of our business strategy, we have pursued, and intend to continue to pursue, selective strategic
acquisitions of businesses, assets and technologies that complement our existing business. For example, we
acquired certain intangible assets, including domain name, software, trademark, customer relationships and non-
competition agreements, in 2009 and 2010. We may make other acquisitions in the future if suitable opportunities
arise. Acquisitions involve uncertainties and risks, including:

(cid:129) potential ongoing financial obligations and unforeseen or hidden liabilities;

(cid:129) failure to achieve the intended objectives, benefits or revenue-enhancing opportunities;

(cid:129) costs and difficulties of integrating acquired businesses and managing a larger business; and

(cid:129) diversion of resources and management attention.

Our failure to address these risks successfully may have a material adverse effect on our financial condition
and results of operations. Any such acquisition may require a significant amount of capital investment, which would
decrease the amount of cash available for working capital or capital expenditures. In addition, if we use our equity
securities to pay for acquisitions, we may dilute the value of our ADSs and the underlying ordinary shares. If we
borrow funds to finance acquisitions, such debt instruments may contain restrictive covenants that could, among
other things, restrict us from distributing dividends. Such acquisitions may also generate significant amortization
expenses related to intangible assets.

Our Japan operations may not be successful.

We formally launched our Japanese search service in January 2008, after completing a 10-month Beta test for
the service. Therefore, we only have limited experience operating in the Japanese market. Moreover, our Japan
operations have incurred operating losses since the inception in December 2006, and it is uncertain when the
business will become profitable, if at all. Additional future losses in our Japan operations could have a material
adverse effect on our overall results of operations.

The Japanese search market is highly competitive and currently is dominated by two companies, Yahoo! Japan
and Google. These companies have significantly greater financial resources, longer operating history and more
experience in the Japanese search market than we do. Moreover, other local providers of competing search services
may also have a substantial advantage over us in attracting users due to their more established brands in Japan,
greater knowledge with respect to the tastes and preferences of Japanese users and their focus on the Japanese
market. If we cannot compete successfully with these competitors in the Japanese language search market, our
business in Japan could be adversely affected.

In addition, there are certain risks inherent in doing business internationally, including:

(cid:129) difficulties in developing, staffing and simultaneously managing a foreign operation as a result of distance,

language and cultural differences;

(cid:129) longer customer payment cycles;

(cid:129) currency exchange rate fluctuations;

(cid:129) political or social unrest or economic instability;

(cid:129) unanticipated changes in laws or regulations;

(cid:129) severe natural disasters, such as the recent earthquake and tsunami in Japan; and

(cid:129) potentially adverse tax consequences.

16

One or more of these factors could harm our Japan operations and consequently, could harm our overall

operating results.

If we are unable to adapt or expand our existing technology infrastructure to accommodate greater traffic
or additional customer requirements, our business may be harmed.

Our Baidu.com website regularly serves a large number of users and customers and delivers a large number of
daily page views. Our technology infrastructure is highly complex and may not provide satisfactory service in the
future, especially as the number of customers using our P4P services increases. We may be required to upgrade our
technology infrastructure to keep up with the increasing traffic on our websites, such as increasing the capacity of
our hardware servers and the sophistication of our software. If we fail to adapt our technology infrastructure to
accommodate greater traffic or customer requirements, our users and customers may become dissatisfied with our
services and switch to our competitors’ websites, which could harm our business.

If we fail to detect fraudulent click-throughs, we could lose the confidence of our customers and our rev-
enues could decline.

We are exposed to the risk of click-through fraud on our paid search results. Click-through fraud occurs when a
person clicks paid search results for a reason other than to view the underlying content of search results. If we find
evidence of past fraudulent clicks, we may have to issue refunds to our customers. If we fail to detect fraudulent
clicks or otherwise are unable to prevent this fraudulent activity, the affected customers may experience a reduced
return on their investment in our online marketing services and lose confidence in the integrity of our systems. If this
happens, we may be unable to retain existing customers and attract new customers for our online marketing
services, and our online marketing revenues could decline. In addition, affected customers may also file legal
actions against us claiming that we have over-charged or failed to refund them. Any such claims or similar claims,
regardless of their merits, could be time-consuming and costly for us to defend against and could also adversely
affect our brand image and our customers’ confidence in the integrity of our systems.

The successful operation of our business depends upon the performance and reliability of the Internet
infrastructure and fixed telecommunications networks in China.

Our business depends on the performance and reliability of the Internet infrastructure in China. Almost all
access to the Internet is maintained through state-owned telecommunication operators under the administrative
control and regulatory supervision of the Ministry of Industry and Information Technology (or its predecessor, the
Ministry of Information Industry, before its formal establishment in 2008), or the MIIT. In addition, the national
networks in China are connected to the Internet through international gateways controlled by the PRC government.
These international gateways are the only channels through which a domestic user can connect to the Internet. We
cannot assure you that a more sophisticated Internet infrastructure will be developed in China. We may not have
access to alternative networks in the event of disruptions, failures or other problems with China’s Internet
infrastructure. In addition, the Internet infrastructure in China may not support the demands associated with
continued growth in Internet usage.

We also rely primarily on China Telecommunications Corporation, or China Telecom, and China United
Network Communications Group Company Limited, or China Unicom, to provide us with data communications
capacity primarily through local telecommunications lines and Internet data centers to host our servers. We have
entered into contracts with various local branches or subsidiaries of China Telecom and China Unicom to obtain
data communications capacity. We have limited access to alternative services in the event of disruptions, failures or
other problems with the fixed telecommunications networks of China Telecom and China Unicom, or if these
companies otherwise fail to provide such services. In 2009, due to connection failures at a China Telecom Internet
data center that hosted our servers, we were unable to provide service for a total of approximately eight hours. Any
unscheduled service interruption could damage our reputation and result in a decrease in our revenues. Furthermore,
we have no control over the costs of the services provided by China Telecom and China Unicom. If the prices that
we pay for telecommunications and Internet services rise significantly, our gross margins could be adversely
affected. In addition, if Internet access fees or other charges to Internet users increase, our user traffic may decrease,
which in turn may harm our revenues.

17

Concerns about the security of electronic commerce transactions and confidentiality of information on
the Internet may reduce use of our network and impede our growth.

A significant barrier to electronic commerce and communications over the Internet in general has been a public
concern over security and privacy, including the transmission of confidential information. If these concerns are not
adequately addressed, they may inhibit the growth of the Internet and other online services generally, especially as a
means of conducting commercial transactions. If a well-publicized Internet breach of security were to occur,
general Internet usage could decline, which could reduce traffic to our websites and impede our growth.

If we fail to maintain an effective system of internal control over financial reporting, we may lose investor
confidence in the reliability of our financial statements.

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
such company’s internal control over financial reporting in its annual report, which contains management’s
assessment of the effectiveness of our internal control over financial reporting. In addition, an independent
registered public accounting firm must attest to and report on the effectiveness of our internal control over financial
reporting. We have been subject to these requirements since the fiscal year ended December 31, 2006.

Our management has concluded that our internal control over financial reporting is effective as of Decem-
ber 31, 2010. See “Item 15. Control and Procedures.” Our independent registered public accounting firm has issued
an attestation report, which has concluded that our internal control over financial reporting is effective in all
material aspects. However, if we fail to maintain effective internal control over financial reporting in the future, our
management and our independent registered public accounting firm may not be able to conclude that we have
effective internal control over financial reporting at a reasonable assurance level. This could in turn result in the loss
of investor confidence in the reliability of our financial statements and negatively impact the trading price of our
ADSs. Furthermore, we have incurred and anticipate that we will continue to incur considerable costs, management
time and other resources in an effort to comply with Section 404 and other requirements of the Sarbanes-Oxley Act.

We have limited business insurance coverage.

The insurance industry in China is still at a relatively early stage of development. Insurance companies in
China offer limited business insurance products. We do not have any business liability or disruption insurance
coverage for our operations in China. Any business disruption may result in our incurring substantial costs and the
diversion of our resources.

We face risks related to health epidemics and other outbreaks.

Our business could be adversely affected by the effects of avian influenza, severe acute respiratory syndrome,
or SARS, or another epidemic or outbreak. In April 2009, a new strain of influenza A virus subtype H1N1,
commonly referred to as “swine flu,” was first discovered in North America and quickly spread to other parts of the
world, including China. In early June 2009, the World Health Organization declared the outbreak to be a pandemic,
while noting that most of the illnesses were of moderate severity. The PRC Ministry of Health subsequently
reported several hundred deaths caused by the influenza A (H1N1). Any outbreaks of avian influenza, SARS, the
influenza A (H1N1) or other adverse public health developments in China may have a material adverse effect on our
business operations. For instance, health or other government regulations adopted in response to an epidemic or
outbreak may require temporary closure of Internet cafes, where many users access our websites, or of our offices.
Such closures would severely disrupt our business operations and adversely affect our results of operations.

18

Risks Related to Our Corporate Structure

PRC laws and regulations governing our businesses and the validity of certain of our contractual
arrangements are uncertain. If we are found to be in violation, we could be subject to sanctions. In addi-
tion, changes in such PRC laws and regulations or changes in interpretations thereof may materially and
adversely affect our business.

There are substantial uncertainties regarding the interpretation and application of PRC laws and regulations,
including, but not limited to, the laws and regulations governing our business, or the enforcement and performance
of our contractual arrangements with our affiliated Chinese entities, namely, Beijing Baidu Netcom Science
Technology Co., Ltd., or Baidu Netcom, Beijing Perusal Technology Co., Ltd., or Beijing Perusal, Beijing
BaiduPay Science and Technology Co., Ltd., or BaiduPay, Baidu HR Consulting (Shanghai), Co., Ltd. or Baidu HR,
and their respective shareholders. We and our PRC subsidiaries, Baidu Online Network Technology (Beijing) Co.,
Ltd., or Baidu Online, Baidu (China) Co., Ltd., or Baidu China, Baidu.com Times Technology (Beijing) Co. Ltd., or
Baidu Times and Baidu International Technology (Shenzhen) Co., Ltd., or Baidu International, are considered
foreign persons or foreign-invested enterprises under PRC foreign investment related laws. As a result, we and our
PRC subsidiaries are subject to PRC legal restrictions on foreign ownership of Internet, online advertising and
employment agency businesses. These laws and regulations are relatively new and may be subject to change, and
their official interpretation and enforcement may involve substantial uncertainty. New laws and regulations that
affect existing and proposed future businesses may also be applied retroactively.

The PRC government has broad discretion in determining penalties for violations of laws and regulations,
including levying fines, revoking business and other licenses and requiring actions necessary for compliance. We
cannot predict the effect of the interpretation of existing or new PRC laws or regulations on our businesses. We
cannot assure you that our current ownership and operating structure would not be found in violation of any current
or future PRC laws or regulations. As a result, we may be subject to sanctions, including fines, and could be required
to restructure our operations or cease to provide certain services. Any of these or similar occurrences could
significantly disrupt our business operations or restrict us from conducting a substantial portion of our business
operations, which could materially and adversely affect our business, financial condition and results of operations.

If the PRC government were to classify P4P services as a form of online advertising or as part of Internet
content provider services, we may have to conduct our P4P business through Baidu Netcom, which would
increase our effective tax rate, and we might be subject to sanctions and required to pay delinquent taxes.

PRC laws and regulations and administrative authorities currently do not classify P4P services as a form of
online advertising or as part of ICP services requiring an ICP license. We conduct our P4P business through our
subsidiaries in the PRC, none of which has the qualification to operate online advertising business or holds an ICP
license. However, we cannot assure you that the PRC government will not classify P4P services as a form of online
advertising or as part of ICP services in the future. If new regulations characterize P4P services as a form of online
advertising or as part of ICP services, we may have to conduct our P4P business through Baidu Netcom, which is
qualified to operate online advertising business and holds an ICP license. This would increase our consolidated
effective tax rate for two reasons. First, advertising revenues generated by Baidu Netcom are subject to a 3%
construction fee for culture undertakings in addition to the 5% business tax. Second, Baidu Netcom is currently
subject to a 25% enterprise income tax rate, as compared to the lower preferential enterprise income tax rates that
our PRC subsidiaries are subject to as of the date of this annual report. Baidu Netcom has applied for the status of
“High and New Technology Enterprise”, which, if approved, may reduce the enterprise income tax rate to 15%. See
“Item 5.A. Operating and Financial Review and Prospects — Operating Results — Taxation” for more information
on PRC business and enterprise income tax as applicable to our subsidiaries and affiliated entities in the PRC.
Moreover, if the change in classification of P4P services were to be retroactively applied, we might be subject to
sanctions, including payment of delinquent taxes and fines. In addition, the classification of P4P services as a form
of online advertising could subject us to an obligation to examine the content of listings of our P4P customers on our
websites and the associated risks. See “— Risks Related to Our Businesses — We may be subject to claims based
on the content found on our websites or the results in our paid search listings.” Such examinations could be
burdensome and increase our operating costs and expenses. Any change in the classification of P4P by the PRC

19

government may significantly disrupt our operations and materially and adversely affect our business, results of
operations and financial conditions.

In order to comply with PRC laws and regulations limiting foreign ownership of Internet, online advertis-
ing and employment agency businesses, we conduct our ICP, online advertising and employment agency
businesses through our consolidated affiliated entities in China by means of contractual arrangements. If
the PRC government determines that these contractual arrangements do not comply with applicable regu-
lations, our business could be adversely affected.

The PRC government restricts foreign investment in Internet, online advertising and employment agency
businesses. Accordingly, we operate our websites and our online advertising business in China through four
consolidated affiliated entities in China. Three of these entities, Baidu Netcom, Beijing Perusal and Baidu HR, are
each owned by individuals designated by us. The other consolidated affiliated entity, BaiduPay, is owned by Baidu
Netcom and an individual designated by us. All of the individual shareholders of these entities are PRC citizens. We
have contractual arrangements with our consolidated affiliated entities and their individual shareholders that allow
us to substantially control these entities. We cannot assure you, however, that we will be able to enforce these
contracts.

Although we believe we comply with current PRC regulations, we cannot assure you that the PRC government
would agree that these operating arrangements comply with PRC licensing, registration or other regulatory
requirements, with existing policies or with requirements or policies that may be adopted in the future. If the PRC
government determines that we do not comply with applicable law, it could revoke our business and operating
licenses, require us to discontinue or restrict our operations, restrict our right to collect revenues, block our websites,
require us to restructure our operations, impose additional conditions or requirements with which we may not be
able to comply, impose restrictions on our business operations or on our customers, or take other regulatory or
enforcement actions against us that could be harmful to our business.

Our contractual arrangements with our consolidated affiliated entities in China and their individual
shareholders may not be as effective in providing control over these consolidated affiliated entities as
direct ownership.

Since PRC law restricts foreign equity ownership in Internet and online advertising companies in China, we
operate our ICP, online advertising and employment agency businesses through our consolidated affiliated entities
in China. We have no equity ownership interest in any of these entities and must rely on contractual arrangements to
control and operate such businesses. These contractual arrangements may not be as effective in providing control
over these consolidated affiliated entities as direct ownership. For example, these entities could fail to take actions
required for our business or fail to maintain our websites despite their contractual obligations to do so. If they fail to
perform their obligations under their respective agreements with us, we may have to rely on legal remedies under
PRC law, which may not be effective. In addition, we cannot assure you that any of their respective individual
shareholders would always act in our best interests.

Our contractual arrangements with our consolidated affiliated entities in China may result in adverse tax
consequences to us.

As a result of our corporate structure and the contractual arrangements between Baidu Online and each of our
consolidated affiliated entities in China, we are effectively subject to the 5% PRC business tax on both revenues
generated by our consolidated affiliated entities’ operations in China and revenues derived from Baidu Online’s
contractual arrangements with these consolidated affiliated entities. Moreover, we would be subject to adverse tax
consequences if the PRC tax authorities were to determine that the contracts between Baidu Online and these
consolidated affiliated entities were not on an arm’s-length basis and therefore constituted a favorable transfer
pricing. Under the new PRC Enterprise Income Tax Law, which became effective on January 1, 2008, an enterprise
must submit its annual tax return together with information on related party transactions to the tax authorities. The
tax authorities may impose reasonable adjustments on taxation if they have identified any related party transactions
that are inconsistent with arm’s-length principles. For example, the PRC tax authorities could request that our
consolidated affiliated entities adjust their taxable income upward for PRC tax purposes. Such a pricing adjustment

20

could adversely affect us by increasing our consolidated affiliated entities’ tax expenses without reducing Baidu
Online’s tax expenses, which could subject our consolidated affiliated entities to interest due on late payments and
other penalties for under-payment of taxes.

We may have exposure to greater than anticipated tax liabilities.

We are subject to income tax, business tax and other taxes in many provinces and cities in China and our tax
structure is subject to review by various local tax authorities. The determination of our provision for income tax and
other tax liabilities requires significant judgment. In the ordinary course of our business, there are many transactions
and calculations where the ultimate tax determination is uncertain. Although we believe our estimates are
reasonable, the ultimate decisions by the relevant tax authorities may differ from the amounts recorded in our
financial statements and may materially affect our financial results in the period or periods for which such
determination is made.

The principal shareholder of Baidu Netcom has potential conflicts of interest with us, which may
adversely affect our business.

Robin Yanhong Li, our chairman and chief executive officer, is also the principal shareholder of Baidu
Netcom. Conflicts of interests between his duties to our company and Baidu Netcom may arise. As Mr. Li is a
director and executive officer of our company, he has a duty of loyalty and care to us under Cayman Islands law
when there are any potential conflicts of interests between our company and Baidu Netcom. Additionally, Mr. Li has
executed an irrevocable power of attorney to appoint the individual designated by us to be his attorney-in-fact to
vote on his behalf on all Baidu Netcom matters requiring shareholder approval. We cannot assure you, however, that
when conflicts of interest arise, Mr. Li will act completely in our interests or that conflicts of interests will be
resolved in our favor. In addition, Mr. Li could violate his employment agreement with us or his legal duties by
diverting business opportunities from us to others. If we cannot resolve any conflicts of interest between us and
Mr. Li, we would have to rely on legal proceedings, which could be expensive, time-consuming and result in the
disruption of our business.

We may be unable to collect long-term loans to the shareholders of our consolidated affiliated entities in
China.

As of the date of this annual report, we have made long-term loans in an aggregate principal amount of
RMB160.0 million (US$24.2 million) to the individual shareholders of our consolidated affiliated entities. We
extended these loans to enable the shareholders to fund the initial capitalization of these entities and, in the case of
Baidu Netcom, subsequent increases in its registered capital. As of the date of this annual report, all of the registered
capital of our consolidated affiliated entities in China has been fully funded. We may in the future provide additional
loans to the individual shareholders of our consolidated affiliated entities in China in connection with any increase
in their capitalization to the extent necessary and permissible under applicable law. Our ability to ultimately collect
these loans will depend on the profitability of these consolidated affiliated entities and their operational needs,
which are uncertain.

Risks Related to Doing Business in China

Adverse changes in economic and political policies of the PRC government could have a material adverse
effect on the overall economic growth of China, which could adversely affect our business.

Most of our business operations are conducted in China. Accordingly, our results of operations, financial
condition and prospects are affected by economic, political and legal developments in China. China’s economy
differs from the economies of most developed countries in many respects, including with respect to the amount of
government involvement, level of development, growth rate, control of foreign exchange and allocation of
resources. While the PRC economy has experienced significant growth in the past three decades, growth has
been uneven across different regions and among various economic sectors of China. The PRC government has
implemented various measures to encourage economic development and guide the allocation of resources. Some of
these measures benefit the overall PRC economy, but may also have a negative effect on us. For example, our

21

financial condition and results of operations may be adversely affected by government control over capital
investments or changes in tax regulations that are applicable to us. Measures to control the pace of economic growth
may cause a decrease in the level of economic activity in China, which in turn could adversely affect our results of
operations and financial condition. In addition, stimulus measures designed to boost the Chinese economy during
the recent global financial crisis may contribute to higher inflation, which could adversely affect our results of
operations and financial condition. For example, certain operating costs and expenses, such as employee com-
pensation and office operating expenses, may increase as a result of higher inflation. Additionally, because a
substantial portion of our assets consists of cash and cash equivalents and short-term investments, high inflation
could significantly reduce the value and purchasing power of these assets.

Uncertainties with respect to the PRC legal system could adversely affect us.

We conduct our business primarily through our subsidiaries and consolidated affiliated entities in China. Our
operations in China are governed by PRC laws and regulations. Our subsidiaries are generally subject to laws and
regulations applicable to foreign investments in China and, in particular, laws applicable to wholly foreign-owned
enterprises. The PRC legal system is based on written statutes. Prior court decisions may be cited for reference but
have limited precedential value.

PRC legislation and regulations have significantly enhanced the protections afforded to various forms of
foreign investments in China for the past three decades. However, China has not developed a fully integrated legal
system and recently-enacted laws and regulations may not sufficiently cover all aspects of economic activities in
China. In particular, because these laws and regulations are relatively new, and because of the limited volume of
published decisions and their nonbinding nature, the interpretation and enforcement of these laws and regulations
involve uncertainties. For example, China enacted the Anti-Monopoly Law, which became effective on August 1,
2008. Because the Anti-Monopoly Law and the related regulations are still new, and there have been very few court
rulings and no judicial or administrative interpretations on certain key concepts used in the law, it is uncertain how
the implementation and enforcement of the Anti-Monopoly Law and the related regulations would affect our
business. Another example would be the Tort Liability Law that became effective on July 1, 2010. In accordance
with the Tort Liability Law, where an Internet service provider is informed or knows that an Internet user is
infringing other persons’ rights and interests through its Internet service but fails to take necessary actions, it shall
be jointly and severally liable with the Internet user as to the damages suffered by the right holders as a result of the
infringing activity known to the Internet service provider. Since the Tort Liability Law was newly enacted, the
interpretation of its applicability and enforceability on Internet search providers remain uncertain, thus we are not
sure how it would affect our business. Furthermore, the PRC legal system is based in part on government policies
and internal rules, some of which are not published on a timely basis or at all. As a result, we may not be aware of our
violation of these policies and rules until some time after the violation. In addition, any litigation in China may be
protracted and result in substantial costs and diversion of resources and management attention.

We may be adversely affected by the complexity, uncertainties and changes in PRC regulation of Internet
business and companies.

The PRC government extensively regulates the Internet industry, including foreign ownership of, and the
licensing and permit requirements pertaining to, companies in the Internet industry. These Internet-related laws and
regulations are relatively new and evolving, and their interpretation and enforcement involve significant uncer-
tainty. As a result, in certain circumstances it may be difficult to determine what actions or omissions may be
deemed to be violations of applicable laws and regulations. Issues, risks and uncertainties relating to PRC
government regulation of the Internet industry include, but are not limited to, the following:

(cid:129) We only have contractual control over our websites. We do not own the websites due to the restriction of
foreign investment in businesses providing value-added telecommunication services in China, including
online information services.

(cid:129) There are uncertainties relating to the regulation of the Internet business in China, including evolving
licensing practices. This means that permits, licenses or operations at some of our companies may be subject
to challenge, or we may not be able to obtain or renew certain permits or licenses, including without

22

limitation an Internet news license, which is issued by the State Council News Office, an Internet culture
business permit, which is issued by the Ministry of Culture, an audio/video program transmission license,
which is issued by the State Administration of Radio, Film and Television, an Internet publication business
license, which is issued by the General Administration of Press and Publication, an online game virtual
currency issuance or trading license, which is issued by the Ministry of Culture, and a surveying and
mapping qualification certificate for Internet map services, which is issued by the State Bureau of Surveying
and Mapping. Failure to obtain or renew permits and license necessary for our operations may significantly
disrupt our business, or subject us to sanctions, requirements to increase capital or other conditions or
enforcement, or compromise enforceability of related contractual arrangements, or have other harmful
effects on us.

(cid:129) New laws and regulations may be promulgated that will regulate Internet activities, including online
advertising and online payment. Other aspects of our online operations may be regulated in the future. If
these new laws and regulations are promulgated, additional licenses may be required for our online
operations. If our operations do not comply with these new regulations at the time they become effective, or
if we fail to obtain any licenses required under these new laws and regulations, we could be subject to
penalties.

In July 2006, the MIIT issued the Notice of the Ministry of Information Industry on Intensifying the
Administration of Foreign Investment in Value-added Telecommunications Services. This notice prohibits domes-
tic telecommunication services providers from leasing, transferring or selling telecommunications business
operating licenses to any foreign investor in any form, or providing any resources, sites or facilities to any foreign
investor for their illegal operation of a telecommunications business in China. According to this notice, either the
holder of a value-added telecommunication business operating license or its shareholders must directly own the
domain names and trademarks used by such license holders in their provision of value-added telecommunication
services. The notice also requires each license holder to have the necessary facilities, including servers, for its
approved business operations and to maintain such facilities in the regions covered by its license.

Baidu Netcom, our PRC affiliated entity that holds the ICP license necessary to conduct our business in China,
received a letter from the MIIT requiring self-assessment and responded timely to the letter. In order to comply with
the notice described above, we have transferred certain domain names primarily used in our business to Baidu
Netcom, Beijing Perusal and Baidu HR, respectively. In addition, we are in the process of transferring certain
trademarks, including pending trademark applications made by Baidu Online, to Baidu Netcom, Beijing Perusal
and Baidu HR, respectively.

The GAPP Notice published on September 28, 2009 restates the general principle set forth in recently
promulgated regulations that foreign investment is not permitted in Internet game operating businesses in China.
The GAPP Notice prohibits foreign investors from participating in Internet game operating businesses via wholly
owned, equity joint venture or cooperative joint venture investments in China, and from controlling and partic-
ipating in such businesses directly or indirectly through contractual or technical support arrangements. We offer
online games provided by our game operator partners on our website. If the past or current ownership structures,
contractual arrangements and businesses of our company, Baidu Netcom is found to be in violation of any existing
or future PRC laws or regulations, including the MII Notice and the GAPP Notice, the relevant regulatory
authorities would have broad discretion in dealing with such violations.

As we enter into new businesses, we may encounter additional regulatory uncertainties. For example, it
remains unclear whether the provision of online payment services by BaiduPay will require BaiduPay to apply for a
value-added telecommunications business operating license for “online data processing and transaction processing
businesses” as provided in the Catalog of Telecommunications Businesses promulgated by the MIIT.

The People’s Bank of China published Measures Concerning Payment Services by Non-financial Institutions,
or the Payment Measures, on June 14, 2010, which took effective from September 1, 2010 and its implementation
rules on December 1, 2010, which took effect on December 1, 2010. According to the Payment Measures and its
implantation rules, non-financial institutions that have been providing monetary transfer services as an intermediary
between payees and payers, including online payment, issuance and acceptance of prepaid card or bank card, and
other payment services as specified by the People’s Bank of China, shall be required to obtain a license from the

23

People’s Bank of China prior to September 1, 2011, in order to continue providing monetary transfer services. It
may be necessary for us to obtain such license to engage in our online payment business. We are in the process of
applying for the license, but we cannot assure you that we will be able to obtain it before September 1, 2011, or at all.

On April 16, 2009, the People’s Bank of China issued a notice regarding the payment and settlement business
carried out by non-financial institutions, or the 2009 PBOC No. 7 Notice. The 2009 PBOC Notice requires non-
financial institutions established before April 16, 2009 engaging in payment and settlement business to register with
the People’s Bank of China before July 31, 2009. According to the 2009 PBOC Notice, such registration shall not be
interpreted as a “permit” granted by the People’s Bank of China. Rather, such registration serves the purposes of
providing a basis for future policy making by the authorities.

In December 2007, the Standing Committee of Beijing Municipal People’s Congress adopted Beijing
Municipal Regulations on Promotion of Informatization, which provide that any individual or enterprise that
conducts business operations through the Internet shall obtain a business license and/or other necessary licenses
prior to operation. The operator of an online marketplace shall be responsible for checking such individual or
enterprise’s licenses. In July 2008, the Beijing Administration for Industry and Commerce promulgated certain
rules for implementing the above-mentioned regulation. According to these rules, any individual or enterprise
failing to obtain a business license may be prohibited from doing business on an e-commerce marketplace operating
in Beijing, such as Baidu Youa, and violation of these rules may lead to penalties on either the individual/enterprise
or the operator of the e-commerce marketplace. Substantial uncertainties exist in terms of the implementation of
these rules, and there are very few public reports regarding actions taken by the Beijing Administration for Industry
and Commerce against any violators in this regard. We cannot predict to what extent these rules will affect our
business operations or future strategy.

On June 3, 2010, the Ministry of Culture issued the Interim Regulations for the Administration of Online
Games, or the Interim Administration of Online Games, which took effect on August 1, 2010. This regulation
applies to business activities relating to online game development and operation, and virtual currencies issuance and
trading. Pursuant to this regulation, all imported online games shall be subject to the approval of the Ministry of
Culture and all domestic online games shall be filed with the Ministry of Culture within thirty days after the
operation of such domestic online games. This regulation also provides that the business entities engaged in the
issuance or trading of virtual currencies for online games are required to obtain the Online Culture Operating
Permit, which specifies the corresponding business scope, prior to their online game operation. We offer online
games provided by our game operator partners and issue online game virtual currencies on our website. Baidu
Netcom has obtained the Online Culture Business Permit for issuing online game virtual currency.

The interpretation and application of existing PRC laws, regulations and policies and possible new laws,
regulations or policies relating to the Internet industry have created substantial uncertainties regarding the legality
of existing and future foreign investments in, and the businesses and activities of, Internet businesses in China,
including our business.

A notice issued by the PRC Ministry of Culture in August 2009 may significantly affect our MP3 search
services.

On August 26, 2009, the PRC Ministry of Culture promulgated the Notice on Strengthening and Improving the
Content Review of Online Music, which is dated August 18, 2009. Among other things, this notice provides that
only “Internet culture operating entities” approved by the Ministry of Culture may engage in the production,
release, dissemination (including providing direct links to music products) and importation of online music
products. We hold an Internet culture business permit granted by the Ministry of Culture, which allows us to engage
in “Internet culture activities” as defined in the relevant regulations promulgated by the Ministry of Culture. See
“Item 4.B. Information on the Company — Business Overview — Regulation — Regulations on Internet Culture
Activities.” However, we cannot assure you that the third-party music websites that our MP3 search services link to
are operated by Internet culture operating entities approved by the Ministry of Culture. If the enforcement of this
notice leads to the closure of a large number of music websites in China, the experience of the users of our MP3
search services could be adversely affected, which could in turn negatively affect our traffic. According to an
interpretation of this notice subsequently posted on the Ministry of Culture’s website, entities that provide direct

24

links to online music products must ensure that music products disseminated by them in such manner have passed
the content review by the Ministry of Culture. It remains unclear how certain aspects of this notice will be
implemented. If we are deemed by the Ministry of Culture to have failed to fully comply with the requirements of
this notice, we could be subject to administrative penalties, including an order to stop providing links to certain
music products, fines, or confiscation of income derived from activities deemed in violation of the notice. Any of
these occurrences could materially and adversely affect our business and results of operations.

Regulation and censorship of information disseminated over the Internet in China may adversely affect
our business and subject us to liability for information displayed on or linked to our websites.

The PRC government has adopted regulations governing Internet access and the distribution of news and other
information over the Internet. Under these regulations, Internet content providers and Internet publishers are
prohibited from posting or displaying over the Internet content that, among other things, violates PRC laws and
regulations, impairs the national dignity of China, or is reactionary, obscene, superstitious, fraudulent or defa-
matory. Failure to comply with these requirements may result in the revocation of licenses to provide Internet
content and other licenses and the closure of the concerned websites. In the past, failure to comply with such
requirements has resulted in the closure of certain websites. The website operator may also be held liable for such
censored information displayed on or linked to the website.

In addition, the MIIT has published regulations that subject website operators to potential liability for content
displayed on their websites and the actions of users and others using their systems, including liability for violations
of PRC laws and regulations prohibiting the dissemination of content deemed to be socially destabilizing. The
Ministry of Public Security has the authority to order any local Internet service provider to block any Internet
website at its sole discretion. From time to time, the Ministry of Public Security has stopped the dissemination over
the Internet of information which it believes to be socially destabilizing. The State Secrecy Bureau is also
authorized to block any website it deems to be leaking state secrets or failing to meet the relevant regulations
relating to the protection of State secrets in the dissemination of online information. Furthermore, we are required to
report any suspicious content to relevant governmental authorities, and to undergo computer security inspections. If
we fail to implement the relevant safeguards against security breaches, our websites may be shut down and our
business and ICP licenses may be revoked. In addition, Internet companies which provide bulletin board systems,
chat rooms or similar services must apply for specific approval from relevant authorities.

Although we attempt to monitor the content in our search results and on our online communities such as Baidu
Post Bar, we are not able to control or restrict the content of other Internet content providers linked to or accessible
through our websites, or content generated or placed on our Baidu Post Bar message boards or our other online
communities by our users. To the extent that PRC regulatory authorities find any content displayed on our websites
objectionable, they may require us to limit or eliminate the dissemination of such information on our websites. If
third-party websites linked to or accessible through our websites operate unlawful activities such as online
gambling on their websites, PRC regulatory authorities may require us to report such unlawful activities to relevant
authorities and to remove the links to such websites, or they may suspend or shut down the operation of such
websites. PRC regulatory authorities may also temporarily block access to certain websites for a period of time for
reasons beyond our control. Any of these actions may reduce our user traffic and adversely affect our business. In
addition, we may be subject to penalties for violations of those regulations arising from information displayed on or
linked to our websites, including a suspension or shutdown of our online operations.

Intensified government regulation of Internet cafes could restrict our ability to maintain or increase user
traffic to our websites.

The PRC government has tightened its regulation of Internet cafes in recent years. In particular, a large number
of unlicensed Internet cafes have been closed. In addition, the PRC government has imposed higher capital and
facility requirements for the establishment of Internet cafes. Furthermore, the PRC government’s policy, which
encourages the development of a limited number of national and regional Internet cafe chains and discourages the
establishment of independent Internet cafes, may slow down the growth of Internet cafes. In June 2002, the Ministry
of Culture, together with other government authorities, issued a joint notice, and in February 2004, the State
Administration for Industry and Commerce issued another notice, suspending the issuance of new Internet cafe

25

licenses. In May 2007, the State Administration for Industry and Commerce reiterated its position not to register any
new Internet cafes in 2007. In 2008 and 2009, the Ministry of Culture, the State Administration for Industry and
Commerce and other relevant government authorities, individually or jointly, issued several notices that provide
various ways to strengthen the regulation of Internet cafes, including investigating and punishing Internet cafes that
accept minors, cracking down on Internet cafes without sufficient and valid licenses, limiting the total number of
Internet cafes and approving Internet cafes within the planning made by relevant authorities, screening unlawful and
adverse games and websites, and improving the coordination of regulation over Internet cafes and online games. So
long as Internet cafes are one of the primary venues for our users to access our websites, any reduction in the
number, or any slowdown in the growth, of Internet cafes in China could limit our ability to maintain or increase
user traffic to our websites.

If our PRC subsidiaries Baidu Online and Baidu Times fail to maintain qualification as “High and
New Technology Enterprise” under the PRC Enterprise Income Tax Law, or if our PRC subsidiary Baidu
China fails to retain its 50% reduced rate tax holiday, or if our PRC subsidiaries declare and distribute
dividends to their respective offshore parent companies, we will be required to pay more taxes, which
could have a material adverse effect on our result of operations.

According to the PRC Enterprise Income Tax Law, or the EIT Law, which became effective on January 1,
2008, as further clarified by subsequent tax regulations implementing the EIT Law, foreign-invested enterprises and
domestic enterprises are subject to enterprise income tax, or EIT, at a uniform rate of 25%. The EIT rate of
enterprises established before March 16, 2007 that were eligible for preferential tax rates according to then effective
tax laws and regulations will gradually transition to the uniform 25% EIT rate by January 1, 2013. In addition,
certain enterprises may still benefit from a preferential tax rate of 15% under the EIT Law if they qualify as “High
and New Technology Enterprises strongly supported by the state,” subject to certain general factors described in the
EIT Law and the related regulations.

In December 2008, our PRC subsidiaries Baidu Online and Baidu Times were designated by the Beijing
Municipal Science and Technology Commission as “High and New Technology Enterprise” under the EIT Law. In
February 2009, Baidu Online and Baidu Times received the High and New Technology Enterprise certificates
jointly issued by the Beijing Municipal Science and Technology Commission, Beijing Finance Bureau, and Beijing
State and Local Tax Bureaus. Therefore, Baidu Online and Baidu Times are entitled to enjoy a preferential tax rate
of 15% as long as they maintain their qualification as “High and New Technology Enterprise.” If either or both of
them fail to maintain the “High and New Technology Enterprise” qualification, their applicable EIT rate may
increase to up to 25%, which could have a material adverse effect on our results of operations. We cannot assure you
that we will be able to maintain our current effective tax rate in the future.

In 2006, our PRC subsidiary Baidu China was designated as a “software enterprise” by the Shanghai Municipal
Information Commission and was entitled to a full exemption from the EIT from 2006 to 2007 and a 50% reduced
rate from 2008 to 2010 based on then-effective tax laws and regulations. On April 24, 2009, the Ministry of Finance
and the State Administration of Taxation jointly promulgated Circular on Issues concerning the Implementation of
Preferential Policies for Enterprise Income Tax, or Caishui Circular 69. According to Caishui Circular 69, subject to
verification, a qualified software enterprise established prior to January 1, 2008 may continue to enjoy the tax
holidays previously granted to it as a “software enterprise.” Where the software enterprise had already started to
enjoy its tax holidays before 2008, it may continue to enjoy the remaining tax holidays from 2008 until the
expiration of such tax holidays. Therefore, Baidu China may continue to enjoy a 50% reduced EIT rate from 2008 to
2010. If Baidu China fails to maintain the qualification as a “software enterprise”, its effective EIT rate will be
increased, which could adversely affect our results of operations.

In addition, under the EIT Law and related regulations, dividends, interests, rent or royalties payable by a
foreign-invested enterprise, such as our PRC subsidiaries, to any of its foreign non-resident enterprise investors, and
proceeds from the disposition of assets (after deducting the net value of such assets) by such foreign enterprise
investor, shall be subject to a 10% withholding tax unless such foreign enterprise investor’s jurisdiction of
incorporation has a tax treaty with China that provides for a reduced rate of withholding tax. Undistributed profits
earned by foreign-invested enterprises prior to January 1, 2008 are exempted from any withholding tax. The British
Virgin Islands, where Baidu Holdings Limited, the direct parent company of our PRC subsidiary Baidu Online, is

26

incorporated, does not have such a tax treaty with China. Baidu (Hong Kong) Limited, which directly owns our PRC
subsidiaries Baidu China and Baidu Times, was incorporated in Hong Kong. Hong Kong has a tax treaty with China
that provides for a 5% withholding tax under certain conditions. However, if Baidu (Hong Kong) Limited is not
considered to be the beneficial owner of dividends paid to it by Baidu China and Baidu Times under a tax notice
promulgated on October 27, 2009, such dividends would be subject to withholding tax at a rate of 10%. See
“Item 5.A. Operating and Financial review and Prospects — Operating Results — Taxation — PRC Enterprise
Income Tax.”

Our PRC subsidiaries historically have not paid dividends to us. If they declare and distribute dividends in the
future, such dividend payments will be subject to withholding tax, which will increase our tax liability and reduce
the amount of cash available to our company.

We may be deemed a PRC resident enterprise under the EIT Law, which could subject us to PRC
taxation on our global income, and which may have a material adverse effect on our results of
operations.

Under the EIT Law and related regulations, an enterprise established outside of the PRC with “de facto
management bodies” within the PRC is considered a PRC resident enterprise and is subject to the EIT at the rate of
25% on its worldwide income. The related regulations define the term “de facto management bodies” as
“establishments that carry out substantial and overall management and control over the manufacturing and
business operations, personnel, accounting, properties, etc. of an enterprise.” The State Administration of
Taxation issued the Notice Regarding the Determination of Chinese-Controlled Overseas Incorporated
Enterprises as PRC Tax Resident Enterprises on the Basis of De Facto Management Bodies, or SAT Circular
82, on April 22, 2009. SAT Circular 82 provides certain specific criteria for determining whether the “de facto
management body” of a Chinese-controlled overseas-incorporated enterprise is located in China. See “Item 5.A.
Operating and Financial review and Prospects — Operating Results — Taxation — PRC Enterprise Income Tax.”
Although SAT Circular 82 applies only to overseas registered enterprises controlled by PRC enterprises, not to those
controlled by PRC individuals, the determining criteria set forth in Circular 82 may reflect the State Administration
of Taxation’s general position on how the “de facto management body” test should be applied in determining the tax
resident status of offshore enterprises, regardless of whether they are controlled by PRC enterprises or individuals.
If we are deemed a PRC resident enterprise, we may be subject to the EIT at 25% on our global income, except that
the dividends we receive from our PRC subsidiaries may be exempt from the EIT to the extent such dividends are
deemed as “dividends among qualified PRC resident enterprises.” If we are considered a resident enterprise and
earn income other than dividends from our PRC subsidiaries, a 25% EIT on our global income could significantly
increase our tax burden and materially and adversely affect our cash flow and profitability.

Under PRC tax laws, dividends payable by us and gains on the disposition of our shares or ADSs may be
subject to PRC taxation.

If we are considered a PRC resident enterprise under the EIT Law, our shareholders and ADS holders who are
deemed non-resident enterprises may be subject to the EIT at the rate of 10% upon the dividends payable by us or
upon any gains realized from the transfer of our shares or ADSs, if such income is deemed derived from China,
provided that (i) such foreign enterprise investor has no establishment or premises in China, or (ii) it has
establishment or premises in China but its income derived from China has no real connection with such
establishment or premises. If we are required under the EIT Law to withhold PRC income tax on our
dividends payable to our non-PRC enterprise shareholders and ADS holders, or if any gains realized from the
transfer of our shares or ADSs by our non-PRC enterprise shareholders and ADS holders are subject to the EIT, your
investment in our shares or ADSs could be materially and adversely affected.

Furthermore, if we are considered a “resident enterprise” and relevant PRC tax authorities consider dividends
we pay with respect to our ADSs or ordinary shares and the gains realized from the transfer of our ADSs or ordinary
shares to be income derived from sources within the PRC, such dividends and gains earned by non-resident
individuals may be subject to PRC individual income tax at a rate of 20%. If we are required under PRC tax laws to
withhold PRC income tax on dividends payable to our non-PRC investors that are non-resident individuals or if you

27

are required to pay PRC income tax on the transfer of our ordinary shares or ADSs, the value of your investment in
our ordinary shares or ADSs may be materially and adversely affected.

Our subsidiaries and consolidated affiliated entities in China are subject to restrictions on paying
dividends and making other payments to us.

We are a holding company incorporated in the Cayman Islands and do not conduct any business operations
other than investing in our subsidiaries and affiliated entities. As a result of our holding company structure, we
currently rely primarily on dividend payments from our subsidiaries in China. However, PRC regulations currently
permit payment of dividends only out of accumulated profits, as determined in accordance with PRC accounting
standards and regulations. Our subsidiaries and consolidated affiliated entities in China are also required to set aside
a portion of their after-tax profits according to PRC accounting standards and regulations to fund certain reserve
funds. The PRC government also imposes controls on the conversion of RMB into foreign currencies and the
remittance of currencies out of China. We may experience difficulties in completing the administrative procedures
necessary to obtain and remit foreign currency. See “— Government control of currency conversion may affect the
value of your investment.” Furthermore, if our subsidiaries or consolidated affiliated entities in China incur debt on
their own in the future, the instruments governing the debt may restrict their ability to pay dividends or make other
payments. If we or any of our subsidiaries in China are unable to receive all of the revenues from our operations
through these contractual or dividend arrangements, we may be unable to pay dividends on our ordinary shares and
ADSs.

Governmental control of currency conversion may affect the value of your investment.

The PRC government imposes controls on the convertibility of RMB into foreign currencies and, in certain
cases, the remittance of currency out of China. We receive almost all of our revenues in RMB. Under our current
structure, our income at the Cayman Islands holding company level will primarily be derived from dividend
payments from our PRC subsidiaries. Shortages in the availability of foreign currency may restrict the ability of our
PRC subsidiaries and consolidated affiliated entities to remit sufficient foreign currency to pay dividends or other
payments to us, or otherwise satisfy their foreign currency denominated obligations. Under existing PRC foreign
exchange regulations, payments of current account items, including profit distributions, interest payments and
expenditures from trade-related transactions, can be made in foreign currencies without prior approval from the
PRC State Administration of Foreign Exchange, or SAFE, by complying with certain procedural requirements.
However, approval from appropriate government authorities is required where RMB is to be converted into foreign
currency and remitted out of China to pay capital expenses such as the repayment of loans denominated in foreign
currencies. The PRC government may also at its discretion restrict access in the future to foreign currencies for
current account transactions. If the foreign exchange control system prevents us from obtaining sufficient foreign
currency to satisfy our currency demands, we may not be able to pay dividends in foreign currencies to our
shareholders, including holders of our ADSs.

PRC regulations relating to the establishment of offshore special purpose companies by PRC residents
and registration requirements for employee stock ownership plans or share option plans may limit our
ability to inject capital into our PRC subsidiaries, limit our subsidiaries’ ability to increase their
registered capital or distribute profits to us, or may otherwise adversely affect us.

SAFE has promulgated several regulations, including SAFE Circular No. 75, effective from November 2005,
and its implementation rule issued in May 2007, that require PRC residents and PRC corporate entities to register
with local branches of SAFE in connection with their direct or indirect offshore investment in an overseas special
purpose vehicle, or SPV, for the purposes of overseas equity financing activities. These regulations apply to our
shareholders who are PRC residents and may apply to any offshore acquisitions that we make in the future.

Under these SAFE regulations, PRC residents who make, or have previously made, direct or indirect
investments in an SPV are required to register those investments. In addition, any PRC resident who is a direct
or indirect shareholder of an SPV is required to update the previously filed registration with the local branch of
SAFE, with respect to that SPV, to reflect any material change involving its round-trip investment, capital variation,
such as an increase or decrease in capital, transfer or swap of shares, merger, division, long-term equity or debt

28

investment or creation of any security interest. Moreover, the PRC subsidiaries of that SPV are required to urge the
PRC resident shareholders to update their SAFE registration with the local branch of SAFE when such updates are
required under applicable SAFE regulations. If any PRC shareholder fails to make the required SAFE registration or
update the previously filed registration, the PRC subsidiaries of that SPV may be prohibited from distributing their
profits and the proceeds from any reduction in capital, share transfer or liquidation, to their SPV parent, and the SPV
may also be prohibited from injecting additional capital into their PRC subsidiaries. Moreover, failure to comply
with the various SAFE registration requirements described above could result in liability under PRC laws for
evasion of applicable foreign exchange restrictions.

We have notified holders of ordinary shares of our company whom we know are PRC residents to register with
the local SAFE branch and update their registrations as required under the SAFE regulations described above. We
are aware that Mr. Robin Yanhong Li, our chairman and chief executive officer and principal shareholder, who is a
PRC resident, has registered with the relevant local SAFE branch. We, however, cannot provide any assurances that
all of our shareholders who are PRC residents will file all applicable registrations or update previously filed
registrations as required by these SAFE regulations. The failure or inability of our PRC resident shareholders to
comply with the registration procedures set forth therein may subject such PRC resident shareholders to fines and
legal sanctions, restrict our cross-border investment activities, or limit our PRC subsidiaries’ ability to distribute
dividends to or obtain foreign exchange-dominated loans from our company.

As it is uncertain how the SAFE regulations described above will be interpreted or implemented, we cannot
predict how these regulations will affect our business operations or future strategy. For example, we may be subject
to more stringent review and approval process with respect to our foreign exchange activities, such as remittance of
dividends and foreign currency-denominated borrowings, which may adversely affect our results of operations and
financial condition. In addition, if we decide to acquire a PRC domestic company, we cannot assure you that we or
the owners of such company, as the case may be, will be able to obtain the necessary approvals or complete the
necessary filings and registrations required by the SAFE regulations. This may restrict our ability to implement our
acquisition strategy and could adversely affect our business and prospects.

In December 2006, the People’s Bank of China promulgated the Administrative Measures of Foreign
Exchange Matters for Individuals, setting forth the respective requirements for foreign exchange transactions
by PRC individuals under either the current account or the capital account. In January 2007, SAFE issued
implementing rules for the Administrative Measures of Foreign Exchange Matters for Individuals, which, among
other things, specified approval requirements for certain capital account transactions such as a PRC citizen’s
participation in the employee stock ownership plans or stock option plans of an overseas publicly listed company.
On March 28, 2007, SAFE promulgated the Application Procedure of Foreign Exchange Administration for
Domestic Individuals Participating in Employee Stock Holding Plan or Stock Option Plan of Overseas-Listed
Company, or the Stock Option Rule. Under the Stock Option Rule, PRC citizens who are granted stock options by
an overseas publicly listed company are required, through a PRC agent or PRC subsidiary of such overseas publicly
listed company, to register with SAFE and complete certain other procedures. We and our PRC employees who have
been granted stock options are subject to these regulations. We have designated our PRC subsidiary Baidu Online to
handle the registration and other procedures required by the Stock Option Rule. If we or our PRC optionees fail to
comply with these regulations in the future, we or our PRC optionees and their local employers may be subject to
fines and legal sanctions.

A regulation adopted in August 2006 establishes more complex procedures for acquisitions conducted by
foreign investors, which could make it more difficult for us to pursue growth through acquisitions.

On August 8, 2006, six PRC regulatory agencies, namely, the PRC Ministry of Commerce, the State Assets
Supervision and Administration Commission, the State Administration of Taxation, the State Administration for
Industry and Commerce, the China Securities Regulatory Commission and SAFE, jointly adopted the Regulations
on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, which became effective on
September 8, 2006 and were later amended on June 22, 2009. Among other things, this regulation established
additional procedures and requirements that could make merger and acquisition activities by foreign investors more
time-consuming and complex. We may grow our business in part by directly acquiring complementary businesses
in China. Complying with the requirements of this regulation to complete such transactions could be time-

29

consuming, and any required approval processes, including obtaining approval from the Ministry of Commerce,
may delay or inhibit our ability to complete such transactions, which could affect our ability to expand our business
or maintain our market share.

Fluctuation in the value of the RMB may have a material adverse effect on your investment.

The value of the RMB against the U.S. dollar and other currencies may fluctuate and is affected by, among
other things, changes in China’s political and economic conditions and foreign exchange policies. On July 21, 2005,
the PRC government changed its decade-old policy of pegging the value of the RMB to the U.S. dollar. Under the
revised policy, the RMB is permitted to fluctuate within a narrow and managed band against a basket of certain
foreign currencies. Between July 21, 2005 and March 25, 2011, the RMB appreciated by approximately 26.2%
against the U.S. dollar, although the pace of appreciation was uneven during the period. It is difficult to predict how
the RMB exchange rates may change in the future.

Our revenues and costs are mostly denominated in RMB, while a significant portion of our financial assets are
denominated in U.S. dollars. At the Cayman Islands holding company level, we rely entirely on dividends and other
fees paid to us by our subsidiaries and consolidated affiliated entities in China. Any significant revaluation of RMB
may materially and adversely affect our cash flows, revenues, earnings and financial position, and the value of, and
any dividends payable on, our ADSs in U.S. dollars. For example, an appreciation of RMB against the U.S. dollar
would make any new RMB denominated investments or expenditures more costly to us, to the extent that we need to
convert U.S. dollars into RMB for such purposes. An appreciation of RMB against the U.S. dollar would also result
in foreign currency translation losses for financial reporting purposes when we translate our U.S. dollar
reporting currency. Conversely, a significant
denominated financial assets into RMB, as RMB is our
depreciation of the RMB against the U.S. dollar may significantly reduce the U.S. dollar equivalent of our
earnings, which in turn could adversely affect the price of our ADSs.

Risks Related to Our ADSs

The 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 fluctuations. The market price
for our ADSs may continue to be volatile and subject to wide fluctuations in response to factors including the
following:

(cid:129) actual or anticipated fluctuations in our quarterly operating results;

(cid:129) changes in financial estimates by securities research analysts;

(cid:129) conditions in Internet search and online marketing markets;

(cid:129) changes in the operating performance or market valuations of other Internet search or Internet companies;

(cid:129) announcements by us or our competitors or other Internet companies of new products, acquisitions, strategic

partnerships, joint ventures or capital commitments;

(cid:129) addition or departure of key personnel;

(cid:129) fluctuations of exchange rates between RMB and the U.S. dollar;

(cid:129) intellectual property litigation; and

(cid:129) general economic or political conditions in China or elsewhere in the world.

In addition, the stock market in general, and the market prices for Internet-related companies and companies
with operations in China in particular, have experienced volatility that often has been unrelated to the operating
performance of such companies. In particular, the global financial crisis and the ensuing economic recessions in
many countries have contributed and may continue to contribute to extreme volatility in the global stock markets.
These broad market and industry fluctuations may adversely affect the price of our ADSs, regardless of our

30

operating performance. Volatility or a lack of positive performance in our ADS price may also adversely affect our
ability to retain key employees, most of whom have been granted options or other equity incentives.

Substantial future sales or the perception of sales of our ADSs in the public market could cause the price
of our ADSs to decline.

Sales of our ADSs in the public market, or the perception that these sales could occur, could cause the market
price of our ADSs to decline. Such sales also might make it more difficult for us to sell equity or equity-related
securities in the future at a time and price that we deem appropriate. If any existing shareholder or shareholders sell a
substantial amount of ADSs, the prevailing market price for our ADSs could be adversely affected. In addition, if we
pay for our future acquisitions in whole or in part with additionally issued ordinary shares, your ownership interests
in our company would be diluted and this, in turn, could have a material adverse effect on the price of our ADSs.

You may not have the same voting rights as the holders of our ordinary shares and may not receive
voting materials in time to be able to exercise your right to vote.

Except as described in this annual report and in the deposit agreement, holders of our ADSs will not be able to
exercise voting rights attached to the shares evidenced by our ADSs on an individual basis. Holders of our ADSs
will appoint the depositary or its nominee as their representative to exercise the voting rights attached to the shares
represented by the ADSs. You may not receive voting materials in time to instruct the depositary to vote, and it is
possible that you, or persons who hold their ADSs through brokers, dealers or other third parties, will not have the
opportunity to exercise a right to vote. Upon our written request, the depositary will mail to you a shareholder
meeting notice which contains, among other things, a statement as to the manner in which your voting instructions
may be given, including an express indication that such instructions may be given or deemed given to the depositary
to give a discretionary proxy to a person designated by us if no instructions are received by the depositary from you
on or before the response date established by the depositary. However, no voting instruction shall be deemed given
and no such discretionary proxy shall be given with respect to any matter as to which we inform the depositary that
(i) we do not wish such proxy given, (ii) substantial opposition exists, or (iii) such matter materially and adversely
affects the rights of shareholders.

You may not be able to participate in rights offerings and may experience dilution of your holdings as a
result.

We may from time to time distribute rights to our shareholders, including rights to acquire our securities.
Under the deposit agreement for the ADSs, the depositary will not offer those rights to ADS holders unless both the
rights and the underlying securities to be distributed to ADS holders are either registered under the Securities Act of
1933, or exempt from registration under the Securities Act with respect to all holders of ADSs. We are under no
obligation to file a registration statement with respect to any such rights or underlying securities or to endeavor to
cause such a registration statement to be declared effective. In addition, we may not be able to take advantage of any
exemptions from registration under the Securities Act. Accordingly, holders of our ADSs may be unable to
participate in our rights offerings and may experience dilution in their holdings as a result.

You may be subject to limitations on transfer of your ADSs.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its transfer
books at any time or from time to time when it deems expedient in connection with the performance of its duties. In
addition, the depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the
books of the depositary are closed, or at any time if we or the depositary deems it advisable to do so because of any
requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or
for any other reason.

You may face difficulties in protecting your interests, and your ability to protect your rights through the
U.S. federal courts may be limited, because we are incorporated under Cayman Islands law, conduct most
of our operations in China and all of our officers reside outside the United States.

We are incorporated in the Cayman Islands, and conduct most of our operations in China through our wholly
owned subsidiaries and consolidated affiliated entities in China. All of our officers and a majority of our directors
reside outside the United States and some or all of the assets of those persons are located outside of the United
States. As a result, it may not be possible to effect service of process within the United States or elsewhere outside
China upon our senior executive officers, including with respect to matters arising under U.S. federal securities laws
or applicable state securities laws.

It may also be difficult or impossible for you to bring an action against us or against our directors and officers in
the Cayman Islands or in China in the event that you believe that your rights have been infringed under the securities
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 you unable to enforce a judgment against our assets or the assets of our directors and officers.
There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the
courts of the Cayman Islands will generally recognize and enforce a non-penal judgment of a foreign court of
competent jurisdiction without retrial on the merits. Moreover, our PRC counsel has advised us that the PRC does
not have treaties with the United States or many other countries providing for the reciprocal recognition and
enforcement of judgment of courts.

Our corporate affairs are governed by our memorandum and articles of association and by the Companies Law
(2010 Revision) and common law of the Cayman Islands. The rights of shareholders to take legal action against our
directors and us, actions by minority shareholders and the fiduciary responsibilities of our 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
the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well
as from English common law, which has persuasive, but not binding, authority on a court in the Cayman Islands.
The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as
clearly established as they would be under statutes or judicial precedents in the United States. In particular, the
Cayman Islands has a less developed body of securities laws as compared to the United States, and provides
significantly less protection to investors. In addition, Cayman Islands companies may not have standing to initiate a
shareholder derivative action before the federal courts of the United States.

As a result of all of the above, our public shareholders may have more difficulty in protecting their interests
through actions against our management, directors or major shareholders than would shareholders of a corporation
incorporated in a jurisdiction in the United States.

Our dual-class ordinary share structure with different voting rights could discourage others from
pursuing any change of control transactions that holders of our Class A ordinary shares and 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 one vote per share, while holders of Class B ordinary shares are entitled to 10 votes
per share. We issued Class A ordinary shares represented by our ADSs in our initial public offering. Certain of our
major shareholders, including our co-founder, chairman and chief executive officer, Robin Yanhong Li, who
acquired our shares prior to our initial public offering, hold our Class B ordinary shares. Each Class B ordinary share
is convertible into one Class A ordinary share at any time by the holder thereof. Class A ordinary shares are not
convertible into Class B ordinary shares under any circumstances. Upon any transfer of Class B ordinary shares by a
holder thereof to any person or entity which is not an affiliate of such holder, such Class B ordinary shares shall be
automatically and immediately converted into the equal number of Class A ordinary shares. In addition, if at any
time Robin Yanhong Li and his affiliates collectively own less than 5% of the total number of the issued and
outstanding Class B ordinary shares, each issued and outstanding Class B ordinary share shall be automatically and
immediately converted into one share of Class A ordinary share, and we shall not issue any Class B ordinary shares
thereafter.

32

Due to the disparate voting powers attached to these two classes, certain shareholders have significant voting
power over matters requiring shareholder approval, including election of directors and significant corporate
transactions, such as a merger or sale of our company or our assets. This concentrated control could discourage or
prevent others from pursuing any potential merger, takeover or other change of control transactions with our
company, which could deprive our shareholders and ADS holders of an opportunity to receive a premium for their
shares or ADSs as part of a sale of our company and might reduce the price of our ADSs.

Our articles of association contain anti-takeover provisions that could adversely affect the rights of
holders of our ordinary shares and ADSs.

Our articles of association include certain provisions that could limit the ability of others to acquire control of
our company, and therefore may deprive the holders of our ordinary shares and ADSs of the opportunity to sell their
shares or ADSs at a premium over the prevailing market price by discouraging third parties from seeking to obtain
control of our company in a tender offer or similar transactions. These provisions include the following:

(cid:129) A dual-class ordinary share structure.

(cid:129) Our board of directors has the authority, without approval by the shareholders, to issue up to a total of
10,000,000 preferred shares in one or more series. Our board of directors may establish the number of shares
to be included in each such series and may fix the designations, preferences, powers and other rights of the
shares of a series of preferred shares.

(cid:129) Our board of directors has the right to elect directors to fill a vacancy created by the increase of the board of
directors or the resignation, death or removal of a director, which prevents shareholders from having the sole
right to fill vacancies on our board of directors.

We may be classified as a passive foreign investment company, which could result in adverse U.S. federal
income tax consequence to U.S. Holders.

Based on the market price of the ADSs and our ordinary shares, the composition of our income and assets and
our operations, we believe that we were not a “passive foreign investment company,” or PFIC, for United States
federal income tax purposes for our taxable year ended December 31, 2010. However, we must make a separate
determination each year as to whether we are a PFIC (after the close of each taxable year) and we cannot assure you
that we will not be a PFIC for our current taxable year ending December 31, 2011 or any future taxable year. A
non-U.S. corporation will be considered a PFIC for any taxable year if either (1) at least 75% of its gross income is
passive income or (2) at least 50% of the value of its assets (based on an average of the quarterly values of the assets
during a taxable year) is attributable to assets that produce or are held for the production of passive income. The
future value of our assets is generally determined by reference to the market price of our ADSs and ordinary shares,
which may fluctuate considerably. If we were treated as a PFIC for any taxable year during which a U.S. Holder held
an ADS or an ordinary share, certain adverse U.S. federal income tax consequences could apply to the U.S. Holder.
See “Item 10.E. Additional Information — Taxation — United States Federal Income Taxation — Passive Foreign
Investment Company.”

Item 4.

Information on the Company

A. History and Development of the Company

We were incorporated in the Cayman Islands in January 2000. Since our inception, we have conducted our
operations in China principally through Baidu Online, our wholly owned subsidiary in Beijing, China. Since June
2001, we also have conducted part of our operations in China through Baidu Netcom, a consolidated affiliated entity
in Beijing, China, which holds the licenses and approvals necessary to operate our websites and provide online
advertising services. In more recent years, we have established additional PRC subsidiaries and assisted in
establishing additional PRC consolidated affiliated entities to conduct part of our operations.

On August 5, 2005, we listed our ADSs on The Nasdaq National Market (later renamed The Nasdaq Global
Market) under the symbol “BIDU.” We and certain selling shareholders of our company completed the initial public
offering of 4,604,224 ADSs, each then representing one Class A ordinary share, on August 10, 2005. On May 12,

33

2010, we effected a change of the ADS to Class A ordinary share ratio from 1 ADS representing 1 Class A ordinary
share to 10 ADSs representing 1 Class A ordinary share. The ratio change has the same effect as a 10-for-1 ADS
split. Our ADSs currently trade on The Nasdaq Global Select Market.

In December 2008, our shareholders approved our name change from Baidu.com, Inc. to Baidu, Inc. In
November 2009, we moved into our new corporate headquarters, which we name as Baidu Campus. Our principal
executive offices are located at Baidu Campus, No. 10 Shangdi 10th Street, Haidian District, Beijing 100085, the
People’s Republic of China. Our telephone number at this address is +86 (10) 5992-8888.

We established Baidu Japan, a subsidiary in Japan, in December 2006. We formally launched the Japanese

search service in January 2008 and now have three subsidiaries in Japan.

In November 2010, we established our subsidiary Baidu USA LLC, or Baidu U.S., a research and development

facility controlled by Baidu Japan Inc. Baidu U.S. is currently in its start-up stage.

B. Business Overview

We are the leading Chinese language Internet search provider. As a technology-based media company, we aim
to provide the best way for people to find information. In addition to serving Internet search users, we provide an
effective platform for businesses to reach potential customers. According to a market survey announced by
iResearch Consulting Group, a third-party market research firm, our search engine Baidu.com accounted for 80.3%
of the total Chinese language web search market in China in 2010, as measured by the number of Chinese language
web search requests handled. According to Alexa.com, our Baidu.com website was the largest website in China, as
measured by user traffic during the three-month period ended December 31, 2010.

In January 2008, we formally launched our Japanese search services at Baidu.jp, run by Baidu Japan. Our
Japanese search services enable users to find relevant information online, including web pages, images, multimedia
files and documents, etc., through links provided on our websites.

We conduct our current operations primarily in China, while our revenues generated from international
operations are insignificant. Revenues generated from our operations in China accounted for approximately 99.9%
in 2008, 99.9% in 2009 and 99.8% in 2010 of our total revenues.

We serve three types of online participants:

Users. We primarily offer a Chinese language search platform on our website Baidu.com as well as a
Japanese language search platform on our website Baidu.jp. We provide Chinese language Internet search
services to enable users to find relevant information online, including web pages, news, images, documents
and multimedia files, through links provided on our websites.

Customers. We design and deliver our online marketing services primarily on our Baidu.com website to
our online marketing customers to whom we provide one or more forms of our online marketing services. In
2010, we had approximately 412,000 active online marketing customers. Our online marketing customers
consist of SMEs throughout China, large domestic corporations and Chinese divisions or subsidiaries of large,
multinational corporations. We have a diverse customer base in terms of industries and geographical locations.
The industries in which our customers operate include medical, machinery, education, software and online
games, tourism and ticketing, transportation, franchising, business services, electronic products, information
technology services, financial services, construction and decoration, household appliances, and other
industries. Customers in the top five industries contributed approximate 50% of our total online marketing
revenues in 2010. Although we have customers located throughout China, we have a more active and larger
customer base in coastal regions, reflecting the current general economic demographics in China.

Baidu Union Members. Baidu Union consists of a large number of third-party web content and
software providers. Baidu Union members can display on their properties our customers’ promotional links
that match the content of such members’ properties. Some Baidu Union members also incorporate a Baidu
search box or toolbar into their websites. Users of Baidu Union members’ websites can conduct search via the
Baidu search box or toolbar and can click on our customers’ promotional links located on Baidu Union
members’ properties. Our relationships with Baidu Union members allow them to provide high-quality and

34

relevant search results to their users without the cost of building and maintaining advanced search capabilities
in-house. Moreover, our Baidu Union members can monetize their traffic and content through revenue sharing
arrangements with us, which are based on the number of click-throughs from their users on our customers’
promotional links. The click-throughs can be either on our customers’ promotional links reached through the
Baidu search box or toolbar located on the Baidu Union members’ websites or directly on our customers’
promotional links located on the Baidu Union Members’ properties. We adopted the differential revenue
sharing policy in 2010, under which the Baidu Union members who bring higher quality and more relevant
click-throughs are awarded with higher revenue sharing ratio. We also closely monitor the effectiveness of our
promotional campaigns to recruit additional Baidu Union members. As a result, the number of Baidu Union
members that contributed revenues to us increased by approximately 11.8% in 2010.

Products and Services for Customers

We focus on providing customers with cost-effective and targeted marketing solutions. We generate almost all
of our revenues from online marketing services, including online marketing services based on search queries, online
marketing services based on contextuals, online marketing services based on search behaviors of Internet users,

40

online marketing services of display placements and online marketing services of other forms. Our online
marketing services generally comprise text links, images, multimedia files and interactive forms.

Online Marketing Services Based on Search Queries

Online marketing services based on search queries are keyword-based marketing services targeted to and
triggered by Internet users’ search queries, which includes our P4P services as well as other online marketing
services based on search queries, for example, Brand-Link. A P4P customer pays us only when users click on one of
its website links on Baidu search result pages or Baidu Union members’ properties while a Brand-Link customer
pays us based on the duration of the placement on Baidu search result pages. Users could reach our P4P sponsored
links via either mobile devices or non-mobile devices.

P4P. Our auction-based P4P services enable our customers to bid for priority placement of their links in
keyword search results. We believe we were the first auction-based P4P service provider in China. Our P4P platform
enables our customers to reach users who search for information related to their products or services. Customers
may use our automated online tools to create text-based descriptions of their web pages and bid on keywords that
trigger the display of their web page information and link. Our P4P platform features an automated online sign-up
process that allows customers to activate their accounts at any time.

Our P4P platform is an online marketplace that introduces Internet search users to customers who bid for
priority placement in the search results. Our intelligent ranking system takes into consideration the “quality factor”
of a keyword in addition to the price bid on the keyword. The quality factor of a keyword is determined based on the
relevance of a keyword and certain other factors. The relevance of a keyword is determined based on our analysis of
past search and click-through results. Links to customers’ websites are ranked according to a comprehensive
ranking index, calculated based on both the quality factor of a keyword and the price bid on that keyword. Our P4P
online marketing customers may choose to set a daily limit on the amount spent and may also choose to target only
users accessing our website from specified regions in China and/or during specific time period of the day.

We also offer certain customers value-added consultative services that help to maximize their return on

investment, including keyword suggestions, account management and performance reporting.

In December 2009, we switched from our previous auction-based online marketing system, which we refer to
as Online Marketing Classic Edition, to our new online marketing system, Phoenix Nest. Through an enhanced
algorithm that generates more relevant advertisements and provides customers with additional
tools and
information to help them better manage their spending and achieves higher ROI, Phoenix Nest is designed to
improve relevance in paid search and increase value for customers, thus driving monetization efficiency. We are
committed to programs designed specifically to retain existing customers and to attract new customers, however,
there is no assurance that we will be able to retain existing customers or continuously attract new customers to use it.
See “Item 3.D. Risk Factors — Risks Related to Our Business — If we fail to retain existing customers or attract
new customers for our online marketing services, our business and growth prospects could be seriously harmed.”

Brand-Link. We offer a brand advertising service, Brand-Link. When Internet users conduct a keyword
search using brand names of our customers who subscribe to our Brand-Link services, the search will generate a
wide range of brand-specific content, including news reports, promotional announcements, product information
and marketing campaigns.

Online Marketing Services Based on Contextuals

Online marketing services based on contextuals refer to our Network Marketing services. Using our ProTheme
contextual promotion technology, we offer Network Marketing, a service that enables our customers’ promotional
links to be displayed on both Baidu web pages and Baidu Union members’ web pages where the customers’ links
are relevant to the subject and content of such web pages. We generate revenues from our Network Marketing
service based on the number of clicks on our customers’ links and share the revenues with our Baidu Union
members for displaying our customers’ promotional links on Baidu Union members’ web pages in accordance with
pre-agreed terms.

41

Online Marketing Services Based on Search Behaviors of Internet Users

Online marketing services based on search behaviors of Internet users include, among others, Targetizement
and Grand Media using our Targetizement technology, both of which enable our customers’ advertisements to
match their targeted Internet users who are automatically identified based on the users’ past behaviors on the
Internet. Targetizement customer pays us a fee based on the number of clicks on their advertisements displayed on
Baidu web pages while Grand Media customer pays us based on a cost per thousand impressions basis for the links
on Baidu Union members’ properties.

Online Marketing Services of Display Placements

Online marketing services of display placements allow our customers to display links not sensitive to search
queries at a designated location on Baidu web pages or Baidu Union members’ properties. Our customers mainly
pay us, among other forms of payments which are less common, based on the duration of the placement on Baidu
search web pages or on a cost per action basis, for example, number of registered users, on Baidu Union members’
properties.

Online Marketing Services of Other Forms

We offer other forms of online marketing services besides the aforesaid services, including directing traffic to
customer’s contents to allow more exposure of these contents to users, and to enable users to purchase and use the
contents via non-mobile devices. Users could also access some of these contents via mobile devices.

Sales and Distribution

We sell our online marketing services directly and through our distribution network. Currently, we have direct

sales presence in Shanghai, Beijing and major cities in Guangdong Province.

Our distributors provide numerous services, including identifying customers, collecting payments, assisting
customers in setting up accounts with us, suggesting keywords to maximize ROI and engaging in other marketing
and educational services aimed at acquiring customers. We offer discounts to distributors as consideration for their
services. We have relied on distributors for several reasons. Our P4P customer base in China is geographically
diverse and fragmented, as many of our P4P customers are SMEs located in different regions in China. Moreover,
SMEs are generally less experienced with online marketing as compared to large companies and therefore benefit
from the extensive services provided by distributors. Finally, secure online payment and credit card systems are in
early stages of development in China. Distributors serve as an important channel to reach SME customers
throughout China and collect payments from them.

We offer our online marketing services to medium and large corporate customers through third-party agencies
and our direct sales force. We have local sales staff in Beijing, Shanghai and major cities in Guangdong Province,
including Shenzhen, Guangzhou, and Dongguan, covering the largest regional markets for our online marketing
services.

Marketing

Historically, our user base grew primarily through word-of-mouth. We focus on continuously improving the
quality of our products and services, as we believe satisfied users and customers are more likely to recommend our
products and services to others. Through these efforts and the increased use of the Internet in China, we have built
our brand with modest marketing expenditures.

Our initial public offering in 2005 and subsequent positive media coverage have significantly enhanced our
brand recognition. In addition, we have implemented a number of marketing initiatives designed to promote our
brand awareness among potential users and customers. For example, we purchased advertisements shown during
CCTV’s 2009 Spring Festival Gala, the most watched show on China’s largest nationwide television network, and
we also purchased advertisements shown during the 2011 Spring Festival on various television channels in China.
We have also conducted cross-marketing activities with a number of leading consumer brands.

42

In addition, with the assistance from our distributors, we conduct localized marketing activities tailored to
potential customers in various regions. We also organize and sponsor seminars and discussion forums targeted at
existing and potential customers.

Competition

The Internet search industry in China is rapidly evolving and highly competitive. Our primary competitors
include U.S.-based Internet search providers providing Chinese language Internet search services and Chinese
Internet companies. We compete with these entities for both users and customers on the basis of user traffic, quality
(relevance) and quantity (index size) of search results, availability and ease of use of our products and services, the
number of customers, distribution channels and the number of associated third-party websites. We also face
competition from traditional advertising media. Furthermore, our instant messaging and e-commerce services face
competition from leading providers of these services in China.

U.S.-based Internet Search Providers. U.S.-based Internet search providers such as Google and Microsoft
have a strong global presence, well-established brand names, more users and customers and significantly greater
financial resources than we do. We may also continue to face competition from other existing competitors and new
entrants in the Chinese language search market.

Chinese Internet Companies. Chinese Internet portals such as Sohu, Netease and Tencent offer a broad range
of online services, including search service. Sohu has its own search engine, “Sogou,” and Tencent also has its own
search engine, “SOSO.” Each of our Chinese competitors has generated significant traffic, a loyal user base and a
large and broad customer base. These portals have widely recognized brand names in China and some have greater
financial resources than we do. We compete with these portals primarily for user traffic and online advertising. In
addition, we compete with B2B service providers such as Alibaba, which also offers search services on its websites.

Other Advertising Media. Other advertising media, such as newspapers, yellow pages, magazines, billboards
and other forms of outdoor media, television and radio, compete for a share of our customers’ marketing budgets.
Large enterprises currently spend a relatively small percentage of their marketing budgets on online marketing as
compared to the percentage they spend on other advertising media.

Instant Messaging and E-commerce Service Providers. Baidu Hi, our instant messaging service, competes
primarily with Tencent’s QQ and MSN Messenger. Baidu Youa, our e-commerce platform, faces competition
primarily from e-commerce service providers such as Alibaba’s Taobao, Tencent’s Paipai, Eachnet, a joint venture
of eBay and Tom Online, 58.com, and Ganji.com.

Technology

We provide our web search and P4P technology using our network of computers running customized software

developed in-house. Our key technologies include:

Web Search Technology

Our web search technology applies a combination of techniques to determine the importance of a web page

independent of a particular search query and the relevance of that page to a particular search query.

Link Analysis Techniques. Link analysis is a technique that determines the relevance between a user query
and a web page by evaluating the combination of the anchor texts and the number of web pages linked to that web
page. We treat a link from web page A to web page B as a “vote” by page A in favor of page B. The subject of the
“vote” is described in the anchor texts of that link. The more “votes” a web page gets, the higher the relevance. We
compare search queries with the content of web pages to help determine relevance. Our text-based scoring
techniques do more than count the number of times a search term appears on a web page. For example, our
technology determines the proximity of individual search terms to each other on a given web page, and prioritizes
results where the search terms are near each other. Other aspects of a page’s content are also considered. By
combining link analysis with our information extraction techniques, we are able to deliver relevant search results.

43

Information Extraction Techniques. We extract information from a web page using high performance
algorithms and information extraction techniques. Our techniques enable us to understand web page content, delete
extraneous data, build link structures, identify duplicate and junk pages and decide whether to include or exclude a
web page based on its quality. Our techniques can process millions of web pages quickly. In addition, our anti-
spamming algorithms and tools can identify and respond to spamming web pages quickly and effectively.

Web Crawling Techniques. Our powerful computer clusters and intelligent scheduling algorithms allow us to
crawl Chinese web pages efficiently. We can easily scale up our system to collect billions of Chinese web pages. Our
spider technology enables us to refresh web indices at intervals ranging from every few minutes to every few weeks.
We set the index refresh frequency rate based on our knowledge of Internet search users’ needs and the nature of the
information. For example, our news index is typically updated every three to five minutes, and can be as frequent as
every minute, throughout the day given the importance of timely information for news. We also mine multimedia
and other forms of files from web page repositories.

In December 2008, we announced Project Aladdin, an ongoing research and development effort aimed at
uncovering useful parts of the “Hidden Web,” the part of the Internet that existing search engine technology may not
be able to index, in order to enrich search results for our users. Aladdin is now a part of Baidu Open Platform.

Chinese Language Processing Techniques. We analyze and understand Chinese web pages by processing
word-segmentation and utilizing an encoding method based on Chinese language characteristics. For example, we
can identify Chinese names on a web page. When a user searches for a person based on the person’s Chinese name,
we can display the web pages that are specifically related to that person. We also mine user behavior and search
interests from our large search query logs. We provide additional web search features such as advanced search, spell
check and search by Chinese phonetics (Pinyin).

P4P Technology

Our P4P platform serves millions of relevant, targeted sponsored links each day based on search terms users

enter or content they view on the web page. Our key P4P technology includes:

P4P Auction System. We use a web-based auction system to enable customers to bid for positions and
automatically deliver relevant, targeted promotional links on Baidu’s properties and Baidu Union members’
properties. The system starts by screening the relevance between the sponsored links and a particular query. Our
intelligent ranking system takes into consideration the quality factor of a keyword in addition to the price bid on the
keyword. The quality factor of a keyword is determined based on the relevance of the keyword and certain other
factors. The relevance of a keyword is determined based on the analysis of past search and click-through results.
Links to customers’ websites are ranked according to a comprehensive ranking index, calculated based on both the
quality factor of a keyword and the price bid or that keyword. We employ a dynamic mechanism for the
determination of the minimum bidding price for each keyword. For determination of cost per click, or CPC, the
system uses an automatic price reducing mechanism which automatically lowers the CPC to the minimum needed
to maintain the desired position.

In December 2009, we completed the switch from Online Marketing Classic Edition, our previous auction-
based online marketing system, to Phoenix Nest, our current online marketing system. Compared with the previous
auction system, Phoenix Nest, which is designed to generate more relevant advertisements, helps customers to more
easily find users’ favorite search terms to bid on, and provides customers with more tools for budget management
and more data for the effective measurement of ROI.

P4P Billing System. We record every click and charge customers a fee by multiplying the number of clicks
by the CPC. Our system is designed to detect fraudulent clicks based on factors such as click patterns and
timestamps. This system also computes the amount a Baidu Union member or a distributor should be paid. The
billing information is integrated with our internal Oracle ERP financial system.

P4P Customer Service System. This system manages customer information such as targeted keywords, costs

per click and performance analysis.

44

ProTheme Contextual Promotion Technology. Our ProTheme technology employs techniques that consider
factors such as theme finding, keyword analysis, word frequency and the overall link structure of the web to analyze
the content of individual web pages and to match sponsored links in our P4P platform to the web pages almost
instantaneously. With this targeting technology, we can automatically provide contextually relevant promotional
links. For example, our technology can provide links offering tickets to fans of a specific sports team or a news story
about that team.

Targetizement Technology

Our Targetizement technology matches our customers’ promotional links with their targeted Internet users.
Our automatic algorithm can analyze a user’s interests based on his or her past search experience and display
promotional links that the user may be interested in viewing.

Large-Scale Systems Technology

We generally use custom software running on clusters of commodity computers. Our investment in our large-
scale system infrastructure has several key benefits: simplification of the storage and processing of large amounts of
data, facilitation of the deployment and operation of large-scale products and services, and automation of much of
the administration of large-scale clusters of computers. Moreover, this large infrastructure is easily scalable to
increases in traffic and dataset volume.

Our large-scale system infrastructure uses distributed software and high performance parallel computing
technologies to provide high-quality web search services and web page collection with low cost computer clusters
on a Linux operating system. We also have management information systems that enable us to perform tasks such as
service operations, administration, trouble-shootings and filtering with relative ease and efficiency. In addition, we
have software systems that can test new ideas with real search queries to evaluate the actual effects without affecting
live services.

Our infrastructure significantly improves the relevance of our search and advertising results by allowing us to
apply superior search and retrieval algorithms that are computationally intensive. We believe this infrastructure also
shortens our product development cycle and allows us to innovate more cost-effectively. We also constantly
evaluate new hardware alternatives and software techniques to help further reduce our computational costs.

Intellectual Property

We rely on a combination of trademark, copyright and trade secret protection laws in China and other
jurisdictions, as well as confidentiality procedures and contractual provisions to protect our intellectual property
and our brand. We have ten issued patents in China and intend to apply for more patents to protect our core
technologies. We also enter into confidentiality, non-compete and invention assignment agreements with our
employees and consultants and nondisclosure agreements with selected third parties. “
” which is our
company’s name “Baidu” in Chinese, has been recognized as a well-known trademark in China by the
Trademark Office under the State Administration for Industry and Commerce. In addition to owning the
trademark “
” and the related logo, we have applied for registration of additional trademarks and logos,
including “
” We also have registered certain trademarks in Hong
Kong, including “

registered our domain name Baidu.com, hao123.com and youa.com with MarkMonitor.com, Baidu.jp with
humeia.co.jp and Baidu.cn, Baidu.com.cn, and certain other websites with China National Network
Information Center, or CNNIC.

Internet, technology and media companies are frequently involved in litigation based on allegations of
infringement or other violations of intellectual property rights. Furthermore, the application of laws governing
intellectual property rights in China and abroad is uncertain and evolving and could involve substantial risks to us.
See “Item 3.D. Key Information — Risk Factors — Risks Related to Our Business — We may face intellectual
property infringement claims and other related claims that could be time-consuming and costly to defend and may
result in our inability to continue providing certain of our existing services” and “— We may be subject to patent
infringement claims with respect to our P4P platform.”

Regulation

The PRC government extensively regulates the telecommunications industry, including the Internet sector.
The State Council, the MIIT and other relevant government authorities have promulgated an extensive regulatory
scheme governing Internet-related services. This section summarizes the principal PRC laws and regulations
relating to our business.

In the opinion of Han Kun Law Offices, our PRC legal counsel: (1) the ownership structure of our company,
Baidu Online, Baidu China, Baidu Times, Baidu Netcom, Beijing Perusal and BaiduPay complies with current PRC
laws and regulations; (2) subject to the disclosure and risks disclosed under “Item 3.D. Key Information — Risk
Factors — Risks Related to Our Corporate Structure,” “— Risks Related to Doing Business in China” and
“Regulation,” our contractual arrangements with Baidu Netcom, Beijing Perusal, BaiduPay, and Baidu HR and
their shareholders are valid and binding on all parties to these arrangements and do not violate existing PRC laws or
regulations; and (3) subject to the disclosure and risks disclosed under “Item 3.D. Key Information — Risk
Factors — Risks Related to Our Corporate Structure,” “— Risks Related to Doing Business in China” and
“Regulation,” the business operations of our company, Baidu Online, Baidu China, Baidu Times, Baidu
Netcom, Beijing Perusal, BaiduPay and Baidu HR, as described herein, comply with current PRC laws and
regulations in all material respects.

China’s Internet industry and online advertising market are at an early stage of development. There are
substantial uncertainties regarding the interpretation and application of existing or proposed PRC laws and
regulations. We cannot assure you that the PRC regulatory authorities would find that our corporate structure
and our business operations comply with PRC laws and regulations. If the PRC government finds us to be in
violation of PRC laws and regulations, we may be required to pay fines and penalties, obtain certain licenses or
permits and change, suspend or discontinue our business operations until we comply with applicable PRC laws and
regulations.

Regulations on Value-Added Telecommunications Services and Internet Content Services

In September 2000, the State Council promulgated the Telecommunications Regulations, or the Telecom
Regulations. The Telecom Regulations categorize all telecommunications businesses in the PRC as either basic or
value-added. Internet content services, or ICP services, are classified as value-added telecommunications
businesses. Under the Telecom Regulations, commercial operators of value-added telecommunications services
must first obtain an operating license from the MIIT or its provincial level counterparts.

In September 2000, the State Council issued the Administrative Measures on Internet Information Services, or
the Internet Measures. According to the Internet Measures, commercial ICP service operators must obtain an ICP
license from the relevant government authorities before engaging in any commercial ICP operations within the
PRC. In November 2000, the MIIT promulgated the Internet Electronic Messaging Service Administrative
Measures, or the BBS Measures. BBS services include electronic bulletin boards, electronic forums, message
boards and chat rooms. The BBS Measures require ICP operators to obtain specific approvals before providing BBS
services. On July 4, 2010, the approval requirement for operating BBS services was terminated by a decision issued
by the PRC State Council. However, in practice, the competent authorities still require the relevant operating
companies to obtain such approval for the operation of BBS services.

In December 2001, the MIIT promulgated the Administrative Measures for Telecommunications Business
Operating License, or the Telecom License Measures. In March 2009, the MIIT issued a revised Telecom License
Measures, which took effect on April 10, 2009. The Telecom License Measures set forth the types of licenses
required to operate value-added telecommunications services and the qualifications and procedures for obtaining
such licenses. For example, an ICP operator providing value-added services in multiple provinces is required to
obtain an inter-regional license, whereas an ICP operator providing the same services in one province is required to
obtain a local license.

National security considerations are an important factor in the regulation of Internet content in China. The
National People’s Congress, the PRC’s national legislature, has enacted laws with respect to maintaining the

46

security of Internet operation and Internet content. According to these laws, as well as the Internet Measures,
violators may be subject to penalties, including criminal sanctions, for Internet content that:

(cid:129) opposes the fundamental principles stated in the PRC constitution;

(cid:129) compromises national security, divulges state secrets, subverts state power or damages national unity;

(cid:129) harms the dignity or interests of the state;

(cid:129) incites ethnic hatred or racial discrimination or damages inter-ethnic unity;

(cid:129) undermines the PRC’s religious policy or propagates heretical teachings or feudal superstitions;

(cid:129) disseminates rumors, disturbs social order or disrupts social stability;

(cid:129) disseminates obscenity or pornography, encourages gambling, violence, murder or fear or incites the

commission of a crime;

(cid:129) insults or slanders a third party or infringes upon the lawful rights and interests of a third party; or

(cid:129) is otherwise prohibited by law or administrative regulations.

ICP operators are required to monitor their websites, including electronic bulletin boards. They may not post or
disseminate any content that falls within these prohibited categories and must remove any such content from their
websites.

The PRC government may shut down the websites of ICP license holders that violate any of the above-

mentioned content restrictions and revoke their ICP licenses.

Tort Liability Law

The Tort Liability Law of the People’s Republic of China became effective on July 1, 2010. In accordance with
the Tort Liability Law, Internet users and Internet service providers shall bear tortious liabilities in the event they
infringe other persons’ rights and interests through the Internet. Where an Internet user conduct tortious acts through
Internet services, the infringed person has the right to request the Internet service provider to take necessary actions
such as deleting contents, screening and delinking; and failing to take necessary actions after being informed will
subject the Internet service provider to joint and several liabilities with the Internet user with regard to the additional
damages incurred. Where an Internet service provider knows an Internet user is infringing other persons’ rights and
interests through its Internet service but fails to take necessary action, it shall be jointly and severally liable with the
Internet user.

Restrictions on Foreign Ownership in Value-Added Telecommunications Services

According to the Provisions on Administration of Foreign Invested Telecommunications Enterprises, or the
FITE Provisions, promulgated by the State Council in December 2001 and amended in September 2008, the
ultimate foreign equity ownership in a value-added telecommunications services provider must not exceed 50%.
Moreover, for a foreign investor to acquire any equity interest in a value-added telecommunication business in
China, it must satisfy a number of stringent performance and operational experience requirements, including
demonstrating good track records and experience in operating value-added telecommunication business overseas.
Foreign investors that meet these requirements must obtain approvals from the MIIT and the Ministry of Commerce
(or the Ministry of Commerce’s authorized local counterparts), which retain considerable discretion in granting
approvals. According to publicly available information, the PRC government has issued telecommunications
business operating licenses to only a limited number of foreign invested companies, all of which are Sino-foreign
joint ventures engaging in the value-added telecommunication business. We believe that it would be impracticable
for us to acquire any equity interest in Baidu Netcom, Beijing Perusal, BaiduPay or Baidu HR without diverting
management attention and resources. In addition, we believe that our contractual arrangements with these entities
and their respective individual shareholders provide us with sufficient and effective control over these entities.
Accordingly, we currently do not plan to acquire any equity interest in any of these entities.

47

In July 2006, the MIIT issued the Notice of the MIIT on Intensifying the Administration of Foreign Investment
in Value-added Telecommunications Services. This notice prohibits domestic telecommunication services
providers from leasing, transferring or selling telecommunications business operating licenses to any foreign
investor in any form, or providing any resources, sites or facilities to any foreign investor for their illegal operation
of a telecommunications business in China. According to this notice, either the holder of a value-added
telecommunication business operating license or its shareholders must directly own the domain names and
trademarks used by such license holders in their provision of value-added telecommunication services. The
notice further requires each license holder to have the necessary facilities, including servers, for its approved
business operations and to maintain such facilities in the regions covered by its license. In addition, all value-added
telecommunication service providers are required to maintain network and Internet security in accordance with the
standards set forth in relevant PRC regulations. If a license holder fails to comply with the requirements in the notice
and cure such non-compliance, the MIIT or its local counterparts have the discretion to take measures against such
license holders, including revoking their valued-added telecommunication business operating licenses.

To comply with these PRC regulations, we operate our websites through Baidu Netcom and Beijing Perusal,
our PRC affiliated entities. In February 2008, we assisted in establishing another consolidated affiliated entity,
BaiduPay, which operate an online payment platform. In 2010, we assisted in establishing consolidated affiliated
entity, Baidu HR, which will provide online employment agency services. Baidu Netcom is wholly owned by our
chairman, chief executive officer and co-founder Robin Yanhong Li and our co-founder Eric Yong Xu, both of
whom are PRC citizens. Beijing Perusal is wholly owned by two PRC citizens designated by our company.
BaiduPay is wholly owned by Baidu Netcom and a PRC citizen designated by our company. Baidu HR is wholly
owned by our chairman, chief executive officer and co-founder Robin Yanhong Li. Each of Baidu Netcom and
Beijing Perusal holds a value-added telecommunications business operating license. It remains unclear whether the
provision of online payment services by BaiduPay will require BaiduPay to apply for a value-added
telecommunications business operating license for “online data processing and transaction processing
businesses” as provided in the Catalog of Telecommunications Businesses promulgated by the MIIT.

To comply with the Notice of the MIIT on Intensifying the Administration of Foreign Investment in Value-
added Telecommunications Services, we have transferred certain domain names primarily used in our business to
Baidu Netcom and Beijing Perusal, respectively, and have transferred certain trademarks to BaiduPay. We are also
in the process of transferring certain trademarks, including pending trademark applications made by Baidu Online,
to Baidu Netcom and Beijing Perusal, respectively. See “Item 3.D. Key Information — Risk Factors — Risks
Related to Doing Business in China — We may be adversely affected by the complexity, uncertainties and changes
in PRC regulation of Internet business and companies.”

Regulations on News Display

Displaying news on a website and disseminating news through the Internet are highly regulated in the PRC. In
November 2000, the State Council News Office and the MIIT promulgated the Provisional Measures for
Administrating Internet Websites Carrying on the News Displaying Business. These measures require an ICP
operator (other than a government authorized news unit) to obtain State Council News Office approval to post news
on its website or disseminate news through the Internet. Furthermore, the disseminated news must come from
government-approved sources pursuant to contracts between the ICP operator and these sources, copies of which
must be filed with the relevant government authorities.

On September 25, 2005, the State Council News Office and the MIIT jointly issued the Provisions on the
Administration of Internet News Information Services, requiring Internet news information service organizations to
provide services as approved by the State Council News Office, subject to annual inspection under the new
provisions. These Provisions also provide that no Internet news information service organizations may take the
form of a foreign invested enterprise, whether a joint venture or a wholly foreign owned enterprise and no
cooperation between Internet news information service organizations and foreign invested enterprise is allowed
prior to the security evaluation by the State Council News Office.

In December 2006, Baidu Netcom obtained the Internet news license, which permits it to publish Internet news
pursuant to the relevant PRC laws and regulations. The Internet news license is subject to annual inspection by
relevant government authorities.

Regulations on Internet Culture Activities

On May 10, 2003, the Ministry of Culture promulgated the Internet Culture Administration Tentative
Measures, or the Internet Culture Measures, which was revised in July 2004. On February 17, 2011, the
Ministry of Culture promulgated a restated Internet Culture Measures, which will take effect from April 1,
2011 to replace the existing Internet Culture Measures. The Internet Culture Measures require ICP operators
engaging in “Internet culture activities” to obtain a permit from the Ministry of Culture. The term “Internet culture
activities” includes, among other things, online dissemination of Internet cultural products (such as audio-video
products, gaming products, performances of plays or programs, works of art and cartoons) and the production,
reproduction, importation, distribution and broadcasting of Internet cultural products. We have hosted certain
audio/video programs on the Baidu Movie channel since 2006. Baidu Netcom was granted an Internet culture
business permit in April 2007, which was renewed in October 2010.

On November 20, 2006, the Ministry of Culture issued Several Suggestions of the Ministry of Culture on the
Development and Administration of the Internet Music, or the Suggestions, which became effective on
November 20, 2006. The Suggestions, among other things, reiterate the requirement for the Internet service
provider to obtain the Internet culture business permit to carry on any business of Internet music products. In
addition, foreign investors are prohibited from engaging in the Internet culture business operation.

On August 26, 2009, the PRC Ministry of Culture promulgated the Notice on Strengthening and Improving the
Content Review of Online Music dated August 18, 2009. According to this notice, only “Internet culture operating
entities” approved by the Ministry of Culture may engage in the production, release, dissemination (including
providing direct links to music products) and importation of online music products. Internet culture operating
entities should establish strict self-monitoring system of online music content and set up special department in
charge of such monitoring.

Regulations on Internet Publishing

The General Administration of Press and Publication and the Ministry of Industry and Information Technology
jointly issued the Interim Provisions for the Administration of Internet Publishing, or the Internet Publishing
Regulations, which became effective on August 1, 2002. The Internet Publishing Regulations authorize the General
Administration of Press and Publication, or GAPP, to grant approval to all entities that engage in Internet
publishing. Pursuant to the Internet Publishing Regulations, the term “Internet publishing” shall mean the act of
online spreading of articles, whereby the Internet information service providers select, edit and process works
created by themselves or others and subsequently post such works on the Internet or transmit such works to the
users’ end via Internet for the public to browse, read, use or download. Baidu Netcom is in the process of applying
for the Internet publication business license.

Regulation on Broadcasting Audio/Video Programs through the Internet

On July 6, 2004, the State Administration of Radio Film and Television promulgated the Rules for the
Administration of Broadcasting of Audio/Video Programs through the Internet and Other Information Networks, or
the A/V Broadcasting Rules. The A/V Broadcasting Rules apply to the opening, broadcasting, integration,
transmission or download of audio/video programs via the Internet and other information networks. Anyone
who wishes to engage in Internet broadcasting activities must first obtain an audio/video program transmission
license, with a term of two years, issued by the State Administration of Radio Film and Television and operate
pursuant to the scope as provided in such license. Foreign invested enterprises are not allowed to engage in the
above business.

On April 13, 2005, the State Council announced Several Decisions on Investment by Non-state-owned
Companies in Culture-related Business in China. These decisions encourage and support non-state-owned
to restrictions and prohibitions for
companies to enter certain culture-related business in China, subject

49

investment in audio/video broadcasting, website news and certain other businesses by non-state-owned companies.
These decisions authorize the Ministry of Culture, the State Administration of Radio Film and Television and the
General Administration of Press and Publication to adopt detailed implementation rules according to these
decisions.

On December 20, 2007, the State Administration of Radio Film and Television and the MIIT jointly issued the
Rules for the Administration of Internet Audio and Video Program Services, commonly known as Document 56,
which came into effect as of January 31, 2008. Document 56 reiterates the requirement set forth in the A/V
Broadcasting Rules that online audio/video service provider must obtain a license from the State Administration of
Radio Film and Television. Furthermore, Document 56 requires all online audio/video service providers to be either
wholly state-owned or state-controlled. According to relevant official answers to press questions published on the
State Administration of Radio Film and Television’s website dated February 3, 2008, officials from the State
Administration of Radio Film and Television and the MIIT clarified that online audio/video service providers that
already had been operating lawfully prior to the issuance of Document 56 may re-register and continue to operate
without becoming state-owned or controlled, provided that such providers have not engaged in any unlawful
activities. This exemption will not be granted to online audio/video service providers established after Document 56
was issued. Baidu Netcom has obtained an audio/video program transmission license, which is valid from January
2010 to January 2013.

Regulations on Payment Services by Non-financial Institutions

transfer services. We are in the process of applying for such license.

Regulations on Advertisements

Industry and Commerce, although there are no national PRC laws or

The PRC government regulates advertising, including online advertising, principally through the State
Administration for
regulations
specifically regulating online advertising business. Under the Rules for Administration of Foreign Invested
Advertising Enterprise, promulgated by the State Administration for Industry and Commerce and the Ministry
of Commerce in March 2004 and amended in October 2008, foreign investors are permitted to own equity interests
in PRC advertising companies. However, foreign investors in wholly foreign-owned and joint venture Chinese
advertising companies are required to have at least three years and two years, respectively, of direct operations in the
advertising industry outside of China. Since we have not been involved in advertising outside of China for the
required number of years, we cannot hold direct equity interests in PRC companies engaged in advertising business.
We conduct our online advertising business through our consolidated affiliated entities in China, Baidu Netcom and
Beijing Perusal.

On November 30, 2004, the State Administration for Industry and Commerce issued the Administrative
Regulations for Advertising Operation Licenses, taking effect as of January 1, 2005, granting a general exemption
to enterprises (other than radio stations, television stations, newspapers and magazines, non-corporate entities and
other entities specified in laws or administrative regulations) from the previous requirement to obtain an advertising
operation license in addition to a business license. We conduct our online advertising business through Baidu
Netcom and Beijing Perusal, each of which holds a business license that includes online advertising in its business
scope.

Advertisers, advertising operators and advertising distributors are required by PRC advertising laws and
regulations to ensure that the contents of the advertisements they prepare or distribute are true and in full
compliance with applicable laws and regulations. In addition, where a special government review is required for

50

certain categories of advertisements before publishing, the advertisers, advertising operators and advertising
distributors are obligated to confirm that such review has been performed and that relevant approval has been
obtained. Violation of these regulations may result in penalties, including fines, confiscation of advertising income,
orders to cease dissemination of the advertisements and orders to publish an advertisement correcting the
misleading information. In circumstances involving serious violations, the State Administration for Industry
and Commerce or its local branches may force the violator to terminate its advertising operation or even revoke its
business license. Furthermore, advertisers, advertising operators or advertising distributors may be subject to civil
liability if they infringe on the legal rights and interests of third parties.

Regulations on Internet Mapping Services

Pursuant to the PRC regulations applicable to Internet mapping services issued by the State Bureau of
Surveying and Mapping, maps called and transmitted through Internet belong to Internet maps. To provide Internet
mapping services, the provider shall apply for a Surveying and Mapping Qualification Certificate for Internet
mapping with the competent surveying and mapping bureau. The PRC regulations also provide for certain
conditions and requirements for issuing the Surveying and Mapping Qualification Certificate, such as the number of
technical personnel and map security verification personnel, security facilities, and approval from relevant
provincial or national government on the service provider’s security system, qualification management and
filings management. Baidu Netcom currently provides online traffic information inquiry services as well as
Internet mapping services and have obtained a Surveying and Mapping Qualification Certificate for Internet
mapping.

Regulations on Software Products

On October 27, 2000, the MIIT issued the Administrative Measures on Software Products, or the Software
Measures, to strengthen the regulation of software products and to encourage the development of the PRC software
industry. On March 1, 2009, the MIIT issued an amended Software Measures, which will become effective on
April 10, 2009. The Software Measures provide a registration and filing system with respect to software products
made in or imported into China. These software products may be registered with the competent local authorities in
charge of software industry administration. Registered software products may enjoy preferential treatment status
granted by relevant software industry regulations. Software products can be registered for five years, and the
registration is renewable upon expiration.

In order to further implement the Computer Software Protection Regulations promulgated by the State Council
on December 20, 2001, the State Copyright Bureau issued the Computer Software Copyright Registration
Procedures on February 20, 2002, which apply to software copyright registration, license contract registration
and transfer contract registration.

Regulations on Online Game Virtual Currency

The Notice to Strengthen the Administration of the Virtual Currency of Online Games jointly promulgated by
Ministry of Culture and Ministry and Commerce in 2009, Interim Administration of Online Games and the Notice
of Implementation of the Interim Administration of Online Games issued by Ministry of Culture in 2010 require
companies that (i) issue online game virtual currency (including prepaid cards and/or pre-payment or prepaid card
points) or (ii) offer online game virtual currency transaction services shall apply for the Online Culture Business
Permit from provincial branches of the Ministry of Culture. The regulations prohibit companies that issue online
game virtual currency from providing services that would enable the trading of such virtual currency. Any company
that fails to submit the requisite application will be subject to sanctions, including but not limited to termination of
operation, confiscation of incomes and fines. The regulations also prohibit online game operators from allocating
virtual items or virtual currency to players based on random selection through lucky draw, wager or lottery which
involves cash or virtual currency directly paid by the players. In addition, companies that issue online game virtual
currency shall comply with certain specific requirements, such as the online games virtual currency shall only be

Regulations on Employment Agency Services

On August 30, 2007, the Standing Committee of the National People’s Congress promulgated the Employment
Promotion Law of the People’s Republic of China which became effective on January 1, 2008, or the Employment
Promotion Law. On November 5, 2007, the Ministry of Human Resources and Social Security of People’s Republic
of China promulgated the Regulations on Employment Service and Employment Management which also became
effective on January 1, 2008, or the Regulations. In accordance with the Employment Promotion Law and the
Regulations, an employment agency, which provides intermediary and other services for recruitment by employers
and job applications by employees, shall obtain a license from the competent labor authority. A wholly foreign
owned enterprise (other than owned by Hong Kong and Macao service providers) is prohibited from conducting
employment agency business. Baidu HR was established recently and has not conducted any employment agency
business. We will apply for the required license prior to the commencement of Baidu HR’s employment agency
business.

Regulations on Intellectual Property Rights

China has adopted legislation governing intellectual property rights, including trademarks, patents and
copyrights. China is a signatory to the main international conventions on intellectual property rights and
became a member of the Agreement on Trade Related Aspects of Intellectual Property Rights upon its
accession to the WTO in December 2001.

Patent. The National People’s Congress adopted the Patent Law in 1984, and amended it in 1992, 2000 and
2008. The purpose of the Patent Law is to protect lawful interests of patent holders, encourage invention, foster
applications of invention, enhance innovative capabilities and promote the development of science and technology.
To be patentable, invention or utility models must meet three conditions: novelty, inventiveness and practical
applicability. Patents cannot be granted for scientific discoveries, rules and methods for intellectual activities,
methods used to diagnose or treat diseases, animal and plant breeds, substances obtained by means of nuclear
transformation or a design which has major marking effect on the patterns or colors of planographic print products
or a combination of both patterns and colors. The Patent Office under the State Council is responsible for receiving,
examining and approving patent applications. A patent is valid for a term of twenty years in the case of an invention
and a term of ten years in the case of utility models and designs. A third-party user must obtain consent or a proper
license from the patent owner to use the patent. Otherwise, the use constitutes an infringement of patent rights.

Copyright. The National People’s Congress adopted the Copyright Law in 1990 and amended it in 2001 and
2010 to widen the scope of works and rights that are eligible for copyright protection. The amended Copyright Law
extends copyright protection to, products disseminated over the Internet and computer software. In addition, there is
a voluntary registration system administered by the China Copyright Protection Center.

To address copyright issues relating to the Internet, the PRC Supreme People’s Court on November 22, 2000
adopted the Interpretations on Some Issues Concerning Applicable Laws for Trial of Disputes over Internet
Copyright, or the Interpretations, which were subsequently amended on December 23, 2003 and November 20,
2006. The Interpretations establish joint liability for ICP operators if they knowingly participate in, assist in or incite
infringing activities or fail to remove infringing content from their websites after receiving notice from the rights
holder. In addition, any act intended to bypass technologies designed to protect copyrights constitutes copyright
infringement. Upon request, the ICP operators must provide the rights holder with registration information of the
alleged violator, provided that such rights holder has produced relevant identification, copyright certificate and
evidence of infringement. An ICP operator is exempted from any liabilities as long as it removes the alleged
infringing content after receiving the rights holder’s notice accompanied with proper evidence.

To address the problem of copyright infringement related to the content posted or transmitted over the Internet,
the PRC National Copyright Administration and the MIIT jointly promulgated the Measures for Administrative
Protection of Copyright Related to Internet on April 29, 2005. This measure became effective on May 30, 2005.

This measure applies to situations where an ICP operator (i) allows another person to post or store any works,
recordings, audio or video programs on the websites operated by such ICP operator or (ii) provides links to, or
search results for, the works, recordings, audio or video programs posted or transmitted by such person, without

52

editing, revising or selecting the content of such material. Upon receipt of an infringement notice from a legitimate
copyright holder, an ICP operator must take remedial actions immediately by removing or disabling access to the
infringing content. If an ICP operator knowingly transmits infringing content or fails to take remedial actions after
receipt of a notice of infringement harming public interest, the ICP operator could be subject to administrative
penalties, including: cessation of infringement activities; confiscation by the authorities of all income derived from
the infringement activities; and payment of a fine of up to three times the unlawful income or, in cases where the
amount of unlawful income cannot be determined, a fine of up to RMB100,000. An ICP operator is also required to
retain all infringement notices for a minimum of six months and to record the content, display time and IP addresses
or the domain names related to the infringement for a minimum of 60 days. Failure to comply with this requirement
could result in an administrative warning and a fine of up to RMB30,000.

On May 18, 2006, the State Council promulgated the Protection of the Right of Communication through
Information Network, which became effective on July 1, 2006. Under this regulation, an Internet service provider
may be exempted from liabilities for providing links to infringing or illegal content if it does not know that such
content is infringing other parties’ rights or is illegal. However, if the legitimate owner of the content notifies the
Internet service provider and requests removal of the links to the infringing content, the Internet service provider
would be deemed to have constructive knowledge upon receipt of such notification but would be exempted from
liabilities if it removes or disconnects the links to the infringing content at the request of the legitimate owner. At the
request of the alleged violator, the Internet service provider should immediately restore links to content previously
disconnected upon receipt of initial non-infringing evidence.

We have adopted measures to mitigate copyright infringement risks. For example, our policy is to remove links
to web pages if we know these web pages contain materials that infringe third-party rights or if we are notified by the
legitimate copyright holder of the infringement with proper evidence.

Trademark. The PRC Trademark Law, adopted in 1982 and revised respectively in 1993 and 2001, protects
registered trademarks. The Trademark Office under the State Administration for Industry and Commerce handles
trademark registrations and grants a term of ten years to registered trademarks. Trademark license agreements must
be filed with the Trademark Office for record. “
” is recognized as a well-known trademark in China by the
Trademark Office under the State Administration for Industry and Commerce. In addition to owning the trademark
“
” and the related logo, we have applied for registration of additional trademarks and logos, including
“

”, and “

”, “

”, “

”.

In September 2002, the CNNIC issued the Implementing Rules for Domain Name Registration setting forth
detailed rules for registration of domain names. On November 5, 2004, the MIIT promulgated the Measures for
Administration of Domain Names for the Chinese Internet, or Domain Name Measures. The Domain Name
Measures regulate the registration of domain names, such as the first tier domain name “.cn.” In February 2006,
CNNIC issued the Measures on Domain Name Disputes Resolution and its implementing rules, pursuant to which
CNNIC can authorize a domain name dispute resolution institution to decide disputes. We have registered Baidu.cn,
Baidu.com.cn, hao123.com and certain other domain names with CNNIC.

Regulations on Information Security

The National People’s Congress has enacted legislation that prohibits use of the Internet that breaches the
public security, disseminates socially destabilizing content or leaks state secrets. Breach of public security includes
breach of national security and infringement on legal rights and interests of the state, society or citizens. Socially
destabilizing content includes any content that incites defiance or violations of PRC laws or regulations or
subversion of the PRC government or its political system, spreads socially disruptive rumors or involves cult
activities, superstition, obscenities, pornography, gambling or violence. State secrets are defined broadly to include
information concerning PRC national defense, state affairs and other matters as determined by the PRC authorities.

According to other relevant regulations, ICP operators must complete mandatory security filing procedures
and regularly update information security and censorship systems for their websites with local public security
authorities, and must also report any public dissemination of prohibited content.

53

In addition, the State Secrecy Bureau has issued provisions authorizing the blocking of access to any website it
deems to be leaking state secrets or failing to comply with the relevant legislation regarding the protection of state
secrets during online information distribution. Specifically, Internet companies in China with bulletin boards, chat
rooms or similar services must apply for specific approval prior to operating such services.

On November 23, 2005, the Ministry of Public Security promulgated Provisions on Technological Measures
for Internet Security Protection, or Internet Protection Measures. The Internet Protection Measures require all ICP
operators to keep records of certain information about its users (including user registration information, log-in and
log-out time, IP address, content and time of posts by users) for at least 60 days and submit the above information as
required by laws and regulations.

As Baidu Netcom and Beijing Perusal are ICP operators, they are subject to the regulations relating to
information security. They have taken measures to comply with such regulations. They are registered with the
relevant government authority in accordance with the mandatory registration requirement. Baidu Netcom’s policy is
to remove links to web pages which to its knowledge contain information that would be in violation of PRC laws or
regulations. In addition, we monitor our websites to ensure our compliance with such laws and regulations.

Regulations on Internet Privacy

The PRC Constitution states that PRC law protects the freedom and privacy of communications of citizens and
prohibits infringement of such rights. In recent years, PRC government authorities have enacted legislation on
Internet use to protect personal information from any unauthorized disclosure. The Internet Measures prohibit an
ICP operator from insulting or slandering a third party or infringing the lawful rights and interests of a third party.
Pursuant to the BBS Measures, ICP operators that provide electronic messaging services must keep users’ personal
information confidential and must not disclose such personal information to any third party without the users’
consent or unless required by law. The regulations further authorize the relevant telecommunications authorities to
order ICP operators to rectify unauthorized disclosure. ICP operators are subject to legal liability if the unauthorized
disclosure results in damages or losses to users. The PRC government, however, has the power and authority to
order ICP operators to turn over personal information if an Internet user posts any prohibited content or engages in
illegal activities on the Internet.

Regulations on Foreign Exchange

Foreign Currency Exchange

Pursuant to the Foreign Currency Administration Rules promulgated in 1996 and amended in 1997 and 2008
and various regulations issued by SAFE and other relevant PRC government authorities, RMB is freely convertible
to the extent of current account items, such as trade related receipts and payments, interest and dividends. Capital
account items, such as direct equity investments, loans and repatriation of investment, unless expressly exempted by
laws and regulations, still require prior approval from SAFE or its provincial branch for conversion of RMB into a
foreign currency, such as U.S. dollars, and remittance of the foreign currency outside the PRC.

Payments for transactions that take place within the PRC must be made in RMB. Unless otherwise approved or
permitted, PRC companies must repatriate foreign currency payments received from abroad. The foreign exchange
received by PRC companies, including foreign invested enterprises, may be retained in their foreign exchange
accounts without being exchanged into RMB to the extent permitted by relevant laws and regulations.

Dividend Distribution

The principal laws and regulations governing dividend distributions by wholly foreign owned enterprises and

Sino-foreign equity joint ventures include:

(cid:129) Wholly Foreign Owned Enterprise Law (1986), as amended;

(cid:129) Wholly Foreign Owned Enterprise Law Implementing Rules (1990), as amended;

(cid:129) Sino-foreign Equity Joint Venture Enterprise Law (1979), as amended;

54

(cid:129) Sino-foreign Equity Joint Venture Enterprise Law Implementing Rules (1983), as amended;

(cid:129) PRC Enterprise Income Tax Law (2007); and

(cid:129) Implementation Rules of the PRC Enterprise Income Tax Law (2007).

Under these laws and regulations, wholly foreign owned enterprises and Sino-foreign equity joint ventures in
the PRC may pay dividends only out of their accumulated profits, if any, as determined in accordance with PRC
accounting standards and regulations. Additionally, these foreign-invested enterprises are required to set aside
certain amounts of their accumulated profits each year, if any, to fund certain reserve funds. These reserves are not
distributable as cash dividends.

Foreign Exchange Registration of Offshore Investment by PRC Residents

Pursuant to SAFE’s Notice on Relevant Issues Concerning Foreign Exchange Administration for PRC
Residents to Engage in Financing and Inbound Investment via Overseas Special Purpose Vehicles, or Circular
No. 75, issued on October 21, 2005, and its implementation rules issued in May 2007, (i) a PRC resident, including a
PRC resident natural person or a PRC company, is required to register with the local branch of SAFE before it
establishes or controls an overseas SPV, or SPV, for the purpose of overseas equity financing (including convertible
debt financing); (ii) when a PRC resident contributes the assets of or its equity interests in a domestic enterprise into
an SPV, or engages in overseas financing after contributing assets or equity interests into an SPV, such PRC resident
shall register his or her interest in the SPVand the change thereof with the local branch of SAFE; and (iii) when the
SPV undergoes a material event outside of China, such as change in share capital or merger and acquisition, the PRC
resident must, within 30 days from the occurrence of such event, register such change with the local branch of
SAFE. PRC residents who are shareholders of SPVs that were established and which have completed their inbound
investment before November 1, 2005 were required to register with the local SAFE branch before March 31, 2006.

Under Circular No. 75, failure to comply with the registration procedures set forth above may result in
penalties, including restrictions on a PRC subsidiary’s foreign exchange activities and its ability to distribute
dividends to the SPV.

On December 25, 2006, the People’s Bank of China promulgated the Measures for the Administration of
Individual Foreign Exchange, and on January 5, 2007 SAFE further promulgated the implementation rules on those
measures. Both became effective on February 1, 2007. According to the implementation rules, if individuals in the
PRC participate in any employee stock ownership plan or stock option plan of an overseas listed company, those
individuals must apply as a group through the company or a domestic agency to SAFE or the appropriate local
branch for approval for any foreign exchange-related transactions concerning that plan.

On March 28, 2007, SAFE promulgated the Application Procedure of Foreign Exchange Administration for
Domestic Individuals Participating in Employee Stock Holding Plan or Stock Option Plan of Overseas-Listed
Company. Under this rule, PRC citizens who are granted stock options by an overseas publicly listed company are
required, through a PRC agent or PRC subsidiary of such overseas publicly-listed company, to register with SAFE
and complete certain other procedures.

Regulations on Labor

On June 29, 2007, the National People’s Congress of China enacted the Labor Contract Law, which became
effective on January 1, 2008. Compared to the Labor Law, the Labor Contract Law establishes more restrictions and
increases costs for employers, including specific provisions related to fixed-term employment contracts, temporary
employment, probation, consultation with the labor union and employee assembly, employment without a contract,
dismissal of employees, compensation upon termination and overtime work, and collective bargaining. According
to the Labor Contract Law, an employer is obliged to sign labor contract with unlimited term with an employee if the
employer continues to hire the employee after the expiration of two consecutive fixed-term labor contracts. The
employer has to compensate the employee upon the expiration of a fixed-term labor contract, unless the employee
refuses to renew such contract on terms the same as or better than those contained in the expired contract. The
employer also has to indemnify an employee if the employer terminates a labor contract without a cause permitted
by law. In addition, under the Regulations on Paid Annual Leave for Employees, which became effective on

55

January 1, 2008, employees who have served more than one year for an employer are entitled to a paid vacation
ranging from 5 to 15 days, depending on their length of service. Employees who waive such vacation time at the
request of employers shall be compensated for three times their regular salaries for each waived vacation day.

Regulations on Taxation

For a discussion of applicable PRC tax regulations, see “Item 5.A. Operating and Financial Review and

Prospects — Operating Results — Taxation.”

Regulations in Japan

Although current Japanese law and regulations contain no provisions expressly directed toward legal control of
Internet search services such as those operated by our Japanese subsidiaries in Japan, certain existing Japanese law
and regulations may nonetheless affect such services. The application to our Japanese subsidiaries of existing
Japanese law and regulations relating to issues such as intellectual property ownership and infringement, obscenity
and other content regulation, user privacy and data protection, defamation, consumer protection and quality of
services in many instances is unclear or unsettled. In all such cases, there is a possibility that providing, editing and
processing by an Internet search service of links to web pages which contain material in violation of applicable
Japanese law could result in civil or criminal legal liability on the part of such Internet search service. In addition to
the foregoing, there is political and social support within Japan for the adoption of legislation expressly directed to
the legal control of harmful information on the Internet. With this support, a law which aims to protect juveniles
from harmful information on the Internet was introduced in June 2008. The law requires Internet service providers,
mobile phone Internet service providers and other Internet related businesses to make efforts to take certain
measures to protect juveniles from harmful information on the Internet such as introducing filtering software. We
conduct our Japan operations in accordance with this law where applicable.

In addition, we own 100% ordinary shares in Qiyi.com Inc., representing 61.11% equity interests in Qiyi.com
Inc. on an as-converted basis. However, we have not consolidated the financial results of Qiyi.com Inc. in our
financial statements under the U.S. GAAP because we are deemed not to have “control” over Qiyi.com Inc. due to
certain substantive participating rights provided to the convertible redeemable preferred shareholder.

PRC laws and regulations restrict foreign investment in Internet, online advertising and employment agency
businesses. Accordingly, we operate our websites and our online advertising business in China through contractual

arrangements with Baidu Netcom, Beijing Perusal, BaiduPay, Baidu HR and their respective individual
shareholders, which allow us to substantially control these entities.

Contractual Arrangements with Baidu Netcom and Its Shareholders

PRC law currently limits foreign equity ownership of companies that provide Internet content and online
advertising businesses. To comply with these foreign ownership restrictions, we operate our websites and provide
online advertising services in China through a series of contractual arrangements with Baidu Netcom and its
shareholders, Robin Yanhong Li and Eric Yong Xu. The following is a summary of these contractual arrangements
as currently in effect.

Exclusive Technology Consulting and Services Agreement. Pursuant

to the exclusive technology
consulting and services agreement between Baidu Online and Baidu Netcom, Baidu Online has the exclusive
right to provide to Baidu Netcom technology consulting and services related to the maintenance of servers, software
development and design of advertisements. Baidu Online also seconds employees to Baidu Netcom for whom
Baidu Netcom bears the costs and expenses. Baidu Online owns the intellectual property rights related to the
software developed by Baidu Online for Baidu Netcom. Baidu Netcom pays monthly service fees to Baidu Online
based upon a pre-agreed formula, which takes into account the number of monthly page views and the basic fee for
every one thousand page views of advertisements displayed on our websites. The basic fee for every one thousand
page views is subject to periodic adjustment. The term of this agreement is ten years from the date thereof.

Baidu Pay-for-Performance Distributors Management Agreement. Pursuant to the Baidu P4P distributors
management agreement between Baidu Netcom and Baidu Online, Baidu Netcom, on behalf of Baidu Online,
manages the marketing distributors in Beijing to promote P4P services and its derivative products and services. The
term of this agreement is one year from the date thereof.

Business Cooperation Agreement. Pursuant to the business cooperation agreement between Baidu Netcom
and Baidu Online, Baidu Netcom provides Internet information services, Internet advertising services and related
services to Baidu Online to enable Baidu Online to provide P4P services on the websites owned and operated by
Baidu Netcom, and Baidu Online provides search engine technology services to Baidu Netcom. The term of this
agreement is ten years from the date thereof.

Operating Agreement. Pursuant to the operating agreement among Baidu Online, Baidu Netcom and the
shareholders of Baidu Netcom, Baidu Online provides guidance and instructions on Baidu Netcom’s daily
operations and financial affairs. The shareholders of Baidu Netcom must designate the candidates
recommended by Baidu Online as their representatives on Baidu Netcom’s board of directors. Baidu Online
has the right to appoint senior executives of Baidu Netcom. In addition, Baidu Online agrees to guarantee Baidu
Netcom’s performance under any agreements or arrangements relating to Baidu Netcom’s business arrangements
with any third party. Baidu Netcom, in return, agrees to pledge its accounts receivable and all of its assets to Baidu
Online. Moreover, Baidu Netcom agrees that without the prior consent of Baidu Online, Baidu Netcom will not
engage in any transactions that could materially affect the assets, liabilities, rights or operations of Baidu Netcom,
including, without limitation, incurrence or assumption of any indebtedness, sale or purchase of any assets or rights,
incurrence of any encumbrance on any of its assets or intellectual property rights in favor of a third party or transfer
of any agreements relating to its business operation to any third party. The term of this agreement is ten years from
the date thereof.

Software License Agreement. Under the software license agreement and its later amendments, Baidu Online
granted Baidu Netcom a non-exclusive, non-assignable and non-transferable right to use “Baidu Chinese Search
Engine” and “Baidu Internet P4P System” software. Baidu Netcom can only use the software on its designated
operating systems to process its internal data. Baidu Online has exclusive rights to set the annual license fee and to
determine the method to calculate such fee. The initial term of the license agreement was five years from the date
thereof and has been extended for another five years.

Other License Agreements. Under these license agreements and their respective later amendments, Baidu
Online granted Baidu Netcom the exclusive right to use the registered domain names and trademarks owned by
Baidu Online and the web layout owned by Baidu Online for the websites operated by Baidu Netcom. Baidu Online

57

has exclusive rights to set the annual license fee and to determine the method to calculate such fee. The initial term
of each license agreement was five years from the date thereof and has been extended for another five years. The
domain name license agreement was extended for another five years in 2010. After the transfers of certain
trademarks (including pending trademark applications) from Baidu Online to Baidu Netcom are completed, the
trademark license agreement will be amended or terminated. We do not expect the termination of these license
agreements to have any material effect on our operations.

Proxy Agreement. Pursuant

to the proxy agreement among Baidu Online, Baidu Netcom and the
shareholders of Baidu Netcom, the shareholders of Baidu Netcom agree to entrust all the rights to exercise
their voting power to the person(s) appointed by Baidu Online. The term of the proxy agreement is 10 years from the
date thereof.

Equity Pledge Agreement. Under the equity pledge agreement between the shareholders of Baidu Netcom
and Baidu Online, the shareholders of Baidu Netcom pledged all of their equity interests in Baidu Netcom to Baidu
Online to guarantee their obligations under the loan agreement and Baidu Netcom’s performance of its obligations
under the exclusive technology consulting and service agreement. If Baidu Netcom or either of its shareholders
breaches its respective contractual obligations, Baidu Online, as pledge, will be entitled to certain rights, including
the right to sell the pledged equity interests. The shareholders of Baidu Netcom agreed not to dispose of the pledged
equity interests or take any actions that would prejudice Baidu Online’s interest. The equity pledge agreement will
expire two years after expiration of the term for fulfillment by Baidu Netcom and its shareholders of their respective
obligations under the exclusive technology consulting and service agreement and the loan agreement.

Exclusive Equity Purchase Option Agreement. Under the exclusive equity purchase option agreement and
its later amendments between the shareholders of Baidu Netcom and Baidu Online, the shareholders of Baidu
Netcom irrevocably granted Baidu Online or its designated person an exclusive option to purchase, to the extent
permitted under PRC law, all or part of the equity interests in Baidu Netcom for the cost of the initial contributions to
the registered capital or the minimum amount of consideration permitted by applicable PRC law. Baidu Online or its
designated person has sole discretion to decide when to exercise the option, whether in part or in full. Baidu Online
or its designated person is the sole beneficiary of any dividends or any other form of the income received by Baidu
Netcom. Baidu Online shall provide unconditional financial support to Baidu Netcom, if in the normal operation of
business, Baidu Netcom shall become in need of any form of reasonable financial support. If Baidu Netcom were to
incur any loss and as a result cannot repay any loans from Baidu Online, Baidu Online shall unconditionally forgive
any such loans to Baidu Netcom given that Baidu Netcom provides sufficient proof for its loss and incapacity to
repay. The term of this agreement is ten years from the date thereof.

Loan Agreement. Under the loan agreement between the shareholders of Baidu Netcom and Baidu Online,
the parties confirmed that Baidu Online had made an RMB2.0 million interest-free loan to the shareholders of Baidu
Netcom solely for the latter to fund the capitalization of Baidu Netcom. The loan can be repaid only with the
proceeds from sale of the shareholder’s equity interest in Baidu Netcom to Baidu Online. The term of the agreement
is ten years from the date thereof.

Irrevocable Power of Attorney. The shareholders of Baidu Netcom have each executed an irrevocable power
of attorney to appoint Xuyang Ren as their attorney-in-fact to vote on their behalf on all Baidu Netcom matters
requiring shareholder approval. The appointment of Xuyang Ren as attorney-in-fact will terminate if Xuyang Ren is
no longer employed by Baidu Online. The term of the power of attorney is ten years from the date thereof.

In February 2006 and March 2008, we extended two additional interest-free loans of RMB8.0 million and
RMB90.0 million, respectively, to Robin Yanhong Li for the sole purpose of increasing the registered capital of
Baidu Netcom. In connection with each loan, we entered into the following agreements with Mr. Li:

(cid:129) a loan agreement;

(cid:129) an equity pledge agreement between Robin Yanhong Li and Baidu Online; and

(cid:129) an exclusive equity purchase option agreement among Robin Yanhong Li, Baidu Netcom and Baidu Online.

The terms of these agreements are similar to the terms of the original agreements between Baidu Online and
the shareholders of Baidu Netcom entered into in March 2005. In addition, under the terms of the original proxy

58

agreement entered into in March 2005, Mr. Li is required to entrust all the rights to exercise the additional voting
power he acquired as a result of his additional investment in the registered capital of Baidu Netcom to the person(s)
appointed by Baidu Online.

Contractual Arrangements with Beijing Perusal and Its Shareholders

the initial capitalization of Beijing Perusal. We entered into a series of agreements with Beijing Perusal and its
shareholders in order to be the primary beneficiary of, and substantially control, Beijing Perusal. Beijing Perusal
became our consolidated affiliated entity as a result of these contractual arrangements. Beijing Perusal holds the

agreements, trademark license agreements and web page copyright license agreements. The domain name
license agreement was terminated in May 2008 because Beijing Perusal already owns the domain names
primarily used in its business. After the transfers of certain pending trademark applications from Baidu
Online to Beijing Perusal are completed, the trademark license agreement will be terminated. We do not
expect the termination of these license agreements to have any material effect on our operations.

The terms of these contractual arrangements are similar to the terms of our contractual arrangements with

Baidu Netcom and its shareholders.

Contractual Arrangements with BaiduPay and Its Individual Shareholder

The terms of these contractual arrangements are similar to the terms of our contractual arrangements with

D. Property, Plant and Equipment

In November 2009, we moved into Baidu Campus, our new corporate headquarters located in Shangdi, an area
designated by the Beijing municipal government as the center of the city’s information technology industry. The
new facility occupies 91,500 square meters of gross floor area and currently houses our principal executive offices,
information and technology center, as well as administrative and support departments, and approximately 4,700 of
our employees. We own the land use right to the land on which Baidu Campus was built. We have offices in Beijing,
Tokyo (Japan), California (USA) and branch offices in Beijing, Shanghai and selected cities in Guangdong
Province, where we lease premises from unrelated third parties.

We host our servers in China at the Internet data centers of China Telecom and China Unicom in Beijing and
Tianjin, and we also have content delivery network locations in various cities across China. In addition, we expect to
use a major data center located in southern China in 2011.

60

We commenced construction of our first self-owned data center in September 2010. This data center, located in

Beijing, is expected to be ready for operation in 2011.

We currently host our servers in Japan at Internet data centers operated by Olympus Business Creation Corp.
and Computer Engineering & Consulting, Ltd., the latter of which will be phased out, as we gradually migrate our
servers to the data center operated by Olympus Business Creation Corp.

Item 4A. Unresolved Staff Comments

None.

Item 5. Operating and Financial Review and Prospects

The following discussion of our financial condition and results of operations is based upon, and should be read
in conjunction with, our consolidated financial statements and the related notes included in this annual report on
Form 20-F. This report contains forward-looking statements. See “Forward-Looking Information.” In evaluating
our business, you should carefully consider the information provided under the caption “Item 3.D. Key
Information — Risk Factors” in this annual report on Form 20-F. We caution you that our businesses and
financial performance are subject to substantial risks and uncertainties.

A. Operating Results

Overview

Our operations are primarily based in China, where we derive almost all of our revenues. Total revenues in
2010 were RMB7.9 billion (US$1.2 billion), a 78.0% increase over 2009. Operating profit in 2010 was
RMB4.0 billion (US$599.8 million), a 146.7% increase over 2009. Net income in 2010 was RMB3.5 billion
(US$534.1 million), a 137.4% increase over 2009.

Our total assets as of December 31, 2010 were RMB11.0 billion (US$1.7 billion), of which cash and cash
equivalent amounted to RMB7.8 billion (US$1.2 billion). Our
liabilities were RMB2.6 billion
(US$400.4 million), accounting for 23.9% of total liabilities and shareholders’ equity. As of December 31,
2010, our retained earnings accumulated to RMB7.0 billion (US$1.1 billion).

total

The major factors affecting our results of operations and financial condition are discussed below.

Revenues

Revenue Generation

We derive almost all of our revenues from online marketing services, which accounted for approximately

99.9%, 99.9% and 100.0% of our total revenues in 2008, 2009 and 2010, respectively.

A substantial majority of our revenues from online marketing services were derived from our P4P services.

Our P4P platform is an online marketplace that introduces Internet search users to customers who pay us a fee
based on click-throughs for priority placement of their links in the search results. We recognize P4P revenues when
a user clicks on a customer’s link in the search results, based on the amount that the customer has agreed to pay for
each click-through.

We also provide to our customers other performance-based online marketing services and time-based online
advertising services. For other performance-based online marketing services, our customers pay us based on
performance criteria other than click-throughs, such as the number of telephone calls brought to our customers, the
number of users registered with our customers, or the number of minimum click-throughs; while for time-based
online advertising services, our customers pay us based on duration of the advertisement placed on our websites.

The most significant factors that directly or indirectly affect our online marketing revenues are:

(cid:129) the number of our users and online marketing customers;

61

(cid:129) the number of searches initiated on our websites and our Baidu Union members’ properties;

(cid:129) the rate at which users click on paid search results;

(cid:129) the competitiveness of bidding for keywords by P4P customers;

(cid:129) the total online marketing budgets of our customers; and

(cid:129) the total number of sponsored links and advertisements displayed on our websites and the bidding price for

each click-through.

Our P4P services revenues have primarily been driven by the increase in the number of page views, the increase
in the number of P4P customers, and by our success in optimizing the display of sponsored links. We believe that an
increase in the number of active P4P customers generally leads to an increase in the number of sponsored links and a
higher average price per click-through for selected keywords. Our P4P customer growth has primarily been driven
by the adoption of our P4P services by SMEs and, to a lesser extent, large enterprises.

In December 2009, we completed the switch from our previous online marketing system, i.e., Online
Marketing Classic Edition, to Phoenix Nest. If Phoenix Nest is perceived to be a less effective marketing tool
than Online Marketing Classic Edition, we may lose existing customers or encounter difficulty attracting new
customers and, as a result, our future revenues could be materially and adversely affected.

Our online marketing services have historically been driven by the general increase in our customers’ online
marketing budgets. We expect the number of our online marketing customers to grow and, as a result, our customer
mix may change. However, we expect our online marketing customer base to remain diverse for the foreseeable
future. Any prolonged economic slowdown in China may cause our customers to decrease or delay their online
marketing spending, hamper our efforts to grow our customer base, or result in fewer clicks by our users on
sponsored links or advertisements displayed on our or Baidu Union members’ websites. Any of these consequences
could negatively affect our online marketing revenues.

Our online marketing customers are increasingly seeking marketing solutions with measurable results in order
to maximize their ROI. To meet our customers’ needs, we will continue to evaluate the effectiveness of our various
products and services and adjust the mix of our service offerings to optimize our customers’ ROI. We expect that we
will continue to earn a substantial majority of our revenues from our online marketing services. As a result, we plan
to continue focusing most of our resources on expanding our online marketing services.

Prior to July 2006, we had provided enterprise search software and related services. We decided to phase out
our enterprise search software business in July 2006. This phase-out was completed in 2008. In 2010, the revenues
recognized for all other services account for 0.03% of our total revenues.

Revenue Collection

We collect payments for our P4P services both from our customers directly and through our distributors. We
have expanded our direct sales effort in several cities in China, including Beijing, Shanghai, Guangzhou, Shenzhen
and Dongguan, and as a result, P4P payments collected through our direct sales have been increasing. We require
our P4P customers to pay a deposit before using our P4P services and remind them by an automated notice to
replenish the accounts after their account balance falls below a designated amount. We deduct the amount due to us
from the deposit paid by a customer when a user clicks on the customer’s link in the search results.

We offer payment terms to some of our customers of other performance-based online marketing services and
time-based online advertising services. In addition, we offer longer payment terms to certain qualified distributors,
consistent with industry practice.

As of December 31, 2010, we had accounts receivable of RMB296.9 million (US$45.0 million), net of
allowance of RMB2.2 million (US$0.3 million), mainly due from customers of other performance-based online
marketing services and time-based online advertising services.

Operating Costs and Expenses

Our operating costs and expenses consist of cost of revenues, selling, general and administrative expenses, and
research and development expenses. Share-based compensation expenses are allocated among the above three
categories of operating costs and expenses, based on the nature of the work of the employees who have received
share-based compensation. Costs and expenses related to our Japan operations, which started in December 2006, are
included in our cost of revenues, selling, general and administrative expenses and research and development
expenses. Our total operating costs and expenses increased significantly from 2008 to 2010 due to the growth of our
business.

Traffic Acquisition Costs. Traffic acquisition costs represent the portion of our online marketing revenues
that we share with our Baidu Union members. We typically pay a Baidu Union member, based on a pre-agreed
arrangement, a portion of the online marketing revenues generated from valid click-throughs by users of that
member’s properties.

Bandwidth Costs. Bandwidth costs are the fees we pay to telecommunications carriers such as China
Telecom and China Unicom for telecommunications services and for hosting our servers at their Internet data
centers. We expect our bandwidth costs, as variable costs, to increase with the increasing number of servers and the
traffic on our websites. Our bandwidth costs could also increase if the telecommunications carriers increase their
service charges.

Depreciation of Servers and Other Equipment. We include depreciation expenses within our cost of revenues
for servers and other computer hardware that are directly related to our business operations and technical support.

Operational Costs. Operational costs include primarily salary and benefit expenses and travel and other
expenses incurred by our operating and technical support personnel. Salary and benefit expenses include wages,
bonuses, medical insurance, unemployment insurance, pension benefits, employee housing fund and other welfare
benefits.

Selling, General and Administrative Expenses

Our selling and marketing expenses primarily consist of salaries and benefits and commissions for our sales
and marketing personnel and promotional and marketing expenses. We expect to incur higher selling and marketing
expenses as we intensify our brand-promotion efforts. To the extent that our direct sales force sells a greater
proportion of our online marketing services, we expect that our selling expenses will increase as a result of increased
sales commissions.

Our general and administrative expenses primarily consist of salaries and benefits for our general and

administrative personnel and fees and expenses for legal, accounting and other professional services.

Research and Development Expenses

Research and development expenses primarily consist of salaries and benefits for research and development
personnel. We expense research and development costs as they are incurred, except for capitalized software
development costs that fulfill the capitalization criteria under Accounting Standards Codification, or ASC, subtopic
350-40, Intangibles-Goodwill and Other: Internal-Use Software.

Share-based Compensation Expenses

We grant options to our employees as a type of share-based compensation award. As of December 31, 2010,
there was RMB51.3 million (US$7.8 million) unrecognized share-based compensation cost related to options,
which is expected to be recognized over a weighted-average vesting period of 2.9 years. To the extent the actual
forfeiture rate is different from our original estimate, actual share-based compensation cost related to these awards
may be different from our expectation.

In addition to options, we started awarding restricted shares to employees in 2006. As of December 31, 2010,
there was RMB162.5 million (US$24.6 million) unrecognized share-based compensation cost related to restricted
shares, which is expected to be recognized over a weighted-average vesting period of 2.7 years. To the extent the
actual forfeiture rate is different from our original estimate, actual share-based compensation cost related to these
awards may be different from our expectation.

Depreciation Expenses of Baidu Campus

Depreciation expenses of Baidu Campus are allocated into cost of revenues and operating expenses based on
the function of the operating units benefiting from the use of the premises. With our move into Baidu Campus and
the termination of certain prior leasing contracts, our leasing expenses decreased by 8.9% in 2010 from 2009.

Taxation

Under the current laws of the Cayman Islands and the British Virgin Islands, we and our direct subsidiary
Baidu Holdings Limited are not subject to income or capital gains tax. Under the current laws of Hong Kong, Baidu
(Hong Kong) Limited is exempted from income tax on its foreign-derived income. Additionally, dividend payments
made by any of these companies are not subject to withholding tax in those jurisdictions.

PRC Enterprise Income Tax

Pursuant to the applicable PRC tax laws and regulations effective before January 1, 2008, foreign-invested
enterprises established in China were generally subject to a state and local enterprise income tax, or EIT, at statutory
rates of 30% and 3%, respectively. An enterprise qualified as a “High and New Technology Enterprise” and located
in a “National High-Tech Development Zone” was entitled to a preferential EIT rate of 15%. In addition, an
enterprise qualified as a “High and New Technology Enterprise” located in the Beijing New Technology Industry
Development Zone was entitled to a preferential EIT rate of 15% and would enjoy an exemption from the EIT for
the first three years of its establishment and, upon approval, a 50% reduction of the EIT for the succeeding three
years.

Baidu Times, which was a certified foreign-invested High and New Technology Enterprise located in Beijing
Zhongguancun Science Park (part of the Beijing New Technology Industry Development Zone), was entitled to a
three-year exemption from EIT from 2006 to 2008 and a 7.5% EIT rate for another three years from 2009 to 2011,
followed by a 15% tax rate so long as it continued to qualify as a High and New Technology Enterprise. Baidu China
was granted “software enterprise” status by the Shanghai Municipal Information Commission in 2006 and thus was
entitled to a full exemption from EIT from 2006 to 2007 and a 50% tax reduction from 2008 to 2010.

On March 16, 2007, the National People’s Congress of China enacted the Enterprise Income Tax Law, or the
EIT Law, which became effective on January 1, 2008. On December 6, 2007, the State Council issued the
Implementation Rules of the Enterprise Income Tax Law, or the Implementation Rules, which also became effective
on January 1, 2008. On December 26, 2007, the State Council issued the Notice on Implementation of Enterprise
Income Tax Transition Preferential Policy under the EIT Law, or the Transition Preferential Policy Circular, which
became effective simultaneously with the EIT Law.

According to the EIT Law, as further clarified by the Implementation Rules and the Transition Preferential
Policy Circular, foreign-invested enterprises and domestic enterprises are subject to EIT at a uniform rate of 25%.
The EIT rate of the enterprises established before March 16, 2007 that were eligible for preferential tax rate

65

according to then effective tax laws and regulations will gradually transition to the uniform 25% EIT rate by
January 1, 2013. In addition, certain enterprises may still benefit from a preferential tax rate of 15% under the EIT
Law if they qualify as “High and New Technology Enterprises strongly supported by the state,” subject to certain
general factors described therein.

Under the Notice on Several Preferential Policies in Respect of Enterprise Income Tax promulgated jointly by
the Ministry of Finance and the State Administration of Taxation on February 22, 2008, or the Caishui No. 1 Notice,
other than the preferential EIT treatments specified under the EIT Law, the Implementation Rules and certain other
tax regulations, all preferential EIT treatments granted prior to January 1, 2008 are eliminated. On April 24, 2009,
the Ministry of Finance and the State Administration of Taxation jointly promulgated Caishui Circular 69.
According to Caishui Circular 69, subject to verification, a qualified software enterprise established prior to
January 1, 2008 may continue to enjoy the tax holidays previously granted to it as a “software enterprise.” Where the
software enterprise had already started to enjoy its tax holidays before 2008, it may continue to enjoy the remaining
tax holidays from 2008 until the expiration of such tax holidays. Therefore, Baidu China may continue to enjoy a
50% reduced EIT rate from 2008 to 2010 as a “software enterprise.”

On April 14, 2008, the Ministry of Science and Technology, the Ministry of Finance and the State
Administration of Taxation jointly issued the Administrative Measures on the Recognition of High and New
Technology Enterprises, or the Recognition Rules, effective on January 1, 2008. According to the Recognition
Rules, the provincial counterparts of the Ministry of Science and Technology, the Ministry of Finance and the State
Administration of Taxation shall jointly determine whether an enterprise is qualified as a high and new technology
enterprise under the EIT Law. In making such determination, these government agencies shall consider, among
other factors, ownership of core technology, whether the products or services fall within the scope of high and new
technology strongly supported by the state as specified in the Recognition Rules, the ratios of technical personnel
and research and development (R&D) personnel to total personnel, the ratio of R&D expenditures to annual sales
revenues, the ratio of revenues attributed to high and new technology products or services to total revenues, and
other measures set forth in relevant guidance.

In December 2008, our PRC subsidiaries Baidu Online and Baidu Times were designated by relevant
government authorities as “High and New Technology Enterprise” under the EIT Law. In February 2009, Baidu
Online and Baidu Times received the High and New Technology Enterprise certificates jointly issued by the Beijing
Municipal Science and Technology Commission, the Beijing Finance Bureau, and the Beijing State and Local Tax
Bureaus. Therefore, Baidu Online and Baidu Times are entitled to enjoy a preferential tax rate of 15% as long as
they maintain their qualification as “High and New Technology Enterprise” under the EIT Law. In addition, Baidu
Times will continue to benefit from the remaining tax holidays granted to it under the applicable PRC tax laws and
regulations effective before January 1, 2008.

Furthermore, in February 2011, Baidu Online was announced as a “Key Software Enterprise” jointly by the
National Development and Reform Commission, Ministry of Industry and Information Technology of the People’s
Republic of China, Ministry of Commerce of the People’s Republic of China, and State Administration of Taxation,
which entitled it to enjoy a preferential income tax rate of 10% in 2010. The status as a “Key Software Enterprise” is
subject to an annual assessment by the relevant governmental authorities in China. Consequently, there is no
assurance that Baidu Online will continue to maintain the status in the future.

If Baidu Online or Baidu Times fails to maintain the “High and New Technology Enterprise” qualification
under the EIT Law, or if Baidu China fails to maintain the qualification as a “software enterprise”, their tax rates will
increase, which could have a material adverse effect on our results of operations.

Under the EIT Law and the Implementation Rules, dividends, interests, rent or royalties payable by a foreign-
invested enterprise, such as our PRC subsidiaries, to any of its foreign non-resident enterprise investors, and
proceeds from the disposition of assets (after deducting the net value of such assets) by such foreign enterprise
investor, shall be subject to a 10% withholding tax unless such foreign enterprise investor’s jurisdiction of
incorporation has a tax treaty with China that provides for a reduced rate of withholding. The Caishui No. 1 Notice
issued on February 22, 2008 further clarifies that undistributed profits earned by foreign-invested enterprises prior
to January 1, 2008 will be exempted from any withholding tax.

66

The British Virgin Islands, where Baidu Holdings Limited, the sole shareholder of our PRC subsidiary Baidu
Online, was incorporated, does not have such a tax treaty with China. Baidu (Hong Kong) Limited, our wholly
owned subsidiary and the sole shareholder of our PRC subsidiaries Baidu China and Baidu Times, was incorporated
in Hong Kong, which has a tax treaty with China that provides for a lower withholding tax rate of 5% under certain
conditions. However, the State Administration of Taxation promulgated Notice on How to Understand and
Determine the Beneficial Owners in Tax Conventions on October 27, 2009, or SAT Circular 601, which
provides guidance for determining whether a resident of a contracting state is the “beneficial owner” with
respect to dividend, interest and royalty income under China’s tax treaties and tax arrangements. According to SAT
Circular 601, a beneficial owner shall have ownership and right to dispose of the income or the rights and properties
giving rise to such income. A beneficial owner generally engages in substantive business activities. An agent or
conduit company will not be regarded as a beneficial owner and, therefore, will not qualify for treaty benefits. The
conduit company normally refers to a company that is set up primarily for the purpose of evading or reducing taxes
or transferring or accumulating profits.

Our PRC subsidiaries historically have not paid dividends to us. If they declare and distribute dividends to us in
the future, such dividend payments will be subject to withholding tax, which will increase our tax liability and
reduce the amount of cash available to our company.

Under the EIT Law and the Implementation Rules, an enterprise established outside of the PRC with “de facto
management bodies” within the PRC is considered a resident enterprise and will be subject to the EIT at the rate of
25% on its worldwide income payable to the tax authority where such “de facto management bodies” locate. The
Implementation Rules define the term “de facto management bodies” as “establishments that carry out substantial
and overall management and control over the manufacturing and business operations, personnel, accounting,
properties, etc. of an enterprise.”

The State Administration of Taxation issued the Notice Regarding the Determination of Chinese-Controlled
Overseas Incorporated Enterprises as PRC Tax Resident Enterprises on the Basis of De Facto Management Bodies,
or SAT Circular 82, on April 22, 2009. SAT Circular 82 provides that an overseas registered enterprise controlled by
a PRC company or a PRC company group will be classified as a “resident enterprise” with its “de facto management
bodies” located within China if the following requirements are satisfied: (i) the senior management and core
management departments in charge of its daily operations function are mainly located in the PRC; (ii) its financial
and human resources decisions are subject to determination or approval by persons or bodies located in the PRC;
(iii) its major assets, accounting books, company seals, and minutes and files of its board and shareholders’
meetings are located or kept in the PRC; and (iv) no less than half of the enterprise’s directors or senior management
with voting rights reside in the PRC. Although SAT Circular 82 only applies to overseas registered enterprises
controlled by PRC enterprises and not those controlled by PRC individuals or foreigners, the determining criteria
set forth in the circular may reflect the State Administration of Taxation’s general position on how the “de facto
management body” test should be applied in determining the tax resident status of offshore enterprises, regardless
of whether they are controlled by PRC enterprises, individuals or foreigners.

If we are deemed a PRC resident enterprise, we may be subject to the EIT at 25% on our global income, except
that the dividends we receive from our PRC subsidiaries may be exempt from the EIT to the extent such dividends
are deemed “dividends among qualified resident enterprises.” If we are considered a resident enterprise and earn
income other than dividends from our PRC subsidiaries, a 25% EIT on our global income could significantly
increase our tax burden and materially and adversely affect our cash flow and profitability.

The EIT Law and the Implementation Rules have made an effort to scrutinize transactions between related
parties. Pursuant to the EIT Law and the Implementation Rules, the tax authorities may impose mandatory
adjustment on tax due to the extent a related party transaction is not in line with arm’s-length principle or was
entered into with a purpose to reduce, exempt or delay the payment of tax. On January 8, 2009, the State
Administration of Taxation issued the Implementation Measures for Special Tax Adjustments (Trial). The measures
set forth tax-filing disclosure and documentation requirements, clarify the definition of “related party”, guide the
selection and application of transfer pricing methods, and outline the due process procedures for transfer pricing
investigation and assessment.

67

If our PRC subsidiaries no longer qualify for preferential tax treatment, we will consider available options
under applicable law that would enable us to qualify for further preferential tax treatment. To the extent we are
unable to offset the impact of the expiration of our PRC subsidiaries’ preferential tax treatment with new tax
exemptions, tax incentives or other tax benefits, the expiration of their preferential tax treatment may cause our
effective tax rate to increase. The amount of income tax payable by our PRC subsidiaries in the future will depend
on various factors, including, among other things, the results of operations and taxable income of, and the statutory
tax rate applicable to, each of the subsidiaries. Our effective tax rate depends partially on the extent of the relative
contribution of each of our subsidiaries to our consolidated taxable income. In 2008, 2009 and 2010, our
consolidated effective tax rate was 9.97%, 11.76% and 13.20%, respectively.

If P4P were classified as a form of advertising in the future, we may have to conduct our P4P business through
Baidu Netcom in order to comply with PRC laws and regulations that limit foreign ownership of online advertising
companies. As a result, our consolidated effective tax rate would increase, as Baidu Netcom is subject to a 25%
statutory enterprise income tax rate as of the date of this annual report. However, Baidu Netcom has applied for the
status of “High and New Technology Enterprise,” which, if approved, may reduce the enterprise income tax rate to
15%.

PRC Business Tax

Revenues from our P4P services are subject to a 5% PRC business tax. Revenues from our online advertising
services are subject to business taxes, surcharges and cultural business construction fees totaling approximately
8.5% of the online advertising revenues. Revenues from our other services are also subject to a 5% business tax.

PRC Urban Maintenance and Construction Tax and Education Surcharge

From December 1, 2010, the Tentative Regulations of the People’s Republic of China on Urban Maintenance
and Construction Tax promulgated in 1985 and the Tentative Rules on Levy of Education Surcharge promulgated in
1986 by the State Council shall be applicable to foreign-invested enterprises, foreign enterprises and individual
foreigners. Laws, regulations, rules and policies on urban maintenance and construction tax and education
surcharge promulgated by the State Council and the finance and tax competent authorities under the State
Council since 1985 shall be also applicable to foreign-invested enterprises, foreign enterprises and individual
foreigners.

Results of Operations

The following table sets forth a summary of our consolidated results of operations for the periods indicated.
Our business has evolved rapidly since we commenced operations in 2000. Our limited operating history makes it
difficult to predict future operating results. We believe that period-to-period comparisons of operating results
should not be relied upon as indicative of future performance.

Year Ended December 31, 2010 Compared to Year Ended December 31, 2009

Revenues. Our total revenues increased by 78.0% from RMB4.4 billion in 2009 to RMB7.9 billion
(US$1.2 billion) in 2010. This increase was due to a substantial
increase in our revenues from online
marketing services. Our online marketing revenues increased by 78.0% from RMB4.4 billion in 2009 to
RMB7.9 billion (US$1.2 million) in 2010. This increase was mainly attributable to the increase in the number
of our online marketing customers from approximately 317,000 in 2009 to over 412,000 in 2010, and the increase in
the average revenue per customer from approximately RMB14,000 in 2009 to approximately RMB19,200
(US$2,909) in 2010. The increase in our online marketing customers was mainly due to our effective
distribution network and our expanded direct sales, especially in Beijing, Shanghai, Guangzhou, Shenzhen and
Dongguan. The increase in the average revenue per customer was primarily attributable to the increase in the
number of paid clicks and the higher price per click as more customers participated in our P4P auction platform. The
number of paid clicks increased by approximately 56.1% from 2009 to 2010.

69

Operating Costs and Expenses. Our total operating costs and expenses increased by 39.2% from
RMB2.8 billion in 2009 to RMB4.0 billion (US$599.4 million) in 2010. This increase was primarily due to
the expansion of our business.

(cid:129) Cost of Revenues. Our cost of revenues increased by 33.0% from RMB1.6 billion in 2009 to
RMB2.1 billion (US$325.7 million) in 2010. This increase was primarily due to the following factors:

(cid:129) Traffic Acquisition Costs. Our traffic acquisition costs increased by 8.7% from RMB697.7 million in
2009 to RMB758.1 million (US$114.9 million) in 2010. Traffic acquisition costs represents 9.6% of total
revenues in 2010, compared to 15.7% in 2009. The decrease in traffic acquisition costs as a percentage of
total revenues is primarily due to Baidu Union’s traffic optimization effort.

(cid:129) Bandwidth Costs and Depreciation Expenses. Our bandwidth costs increased by 52.3% from
RMB203.9 million in 2009 to RMB310.5 million (US$47.1 million) in 2010. Our depreciation
expenses of servers and other equipment increased by 32.2% from RMB251.0 million in 2009 to
RMB331.7 million (US$50.3 million) in 2010. The absolute increases in these costs were due to the
expansion of our business. However, these costs in 2010 accounted for a lower percentage of total
revenues than in 2009. The decreases in bandwidth costs and depreciation expenses as percentages of total
revenues reflect our improved efficiency as well as the scalability of our Internet-based business model.

(cid:129) Business Tax and Surcharges. Our business tax and surcharges increased by 83.0% from
RMB275.9 million in 2009 to RMB504.8 million (US$76.5 million) in 2010, primarily as a result of
the increase in our online marketing revenues.

(cid:129) Operational Costs. Our operational costs increased by 31.1% from RMB181.4 million in 2009 to
RMB237.8 million (US$36.0 million) in 2010, primarily due to the increase in consumption of durable
computer parts in our inventory and higher compensation paid to our operation and technical support staff.

(cid:129) Selling, General and Administrative Expenses. Our selling, general and administrative expenses increased
by 35.4% from RMB804.0 million in 2009 to RMB1.1 billion (US$165.0 million) in 2010. This increase was
primarily due to the following factors:

(cid:129) total salaries and benefits and staff-related expenses increased by 36.5% from RMB400.3 million in 2009
to RMB546.5 million (US$82.8 million) in 2010, primarily due to the increased direct sales headcount to
support our expanded online marketing services;

(cid:129) total office operating expenses increased by 27.2% from RMB85.5 million in 2009 to RMB108.8 million
(US$16.5 million) in 2010, primarily as a result of increase and expansion of our direct sales offices;

(cid:129) total

traveling, communication and business development expenses increased by 23.0% from
RMB30.8 million in 2009 to RMB37.9 million (US$5.7 million) in 2010, primarily due to the
increased direct sales headcount and activities to support our expanded online marketing services; and

(cid:129) marketing and promotion expenses increased by 35.6% from RMB159.0 million in 2009 to
in 2010 primarily due to the increased marketing and

RMB215.6 million (US$32.7 million)
promotion activities.

The above increases were partially offset by a 4.8% decrease in share-based compensation expenses
allocated to selling, general and administrative expenses from RMB38.7 million in 2009 to
RMB36.8 million (US$5.6 million) in 2010, primarily due to the cancellation of some share-based
awards granted to our former officers in prior years.

(cid:129) Research and Development Expenses. Our research and development expenses increased by 69.9% from
RMB422.6 million in 2009 to RMB718.0 million (US$108.8 million) in 2010, primarily due to an increase
in the number and compensation levels of research and development staff.

Operating Profit. As a result of the foregoing, we generated an operating profit of RMB4.0 billion

(US$599.8 million) in 2010, a 146.7% increase from 2009.

70

Taxation. Our

income tax expenses increased by 170.7% from RMB198.0 million in 2009 to
RMB536.0 million (US$81.2 million) in 2010, primarily due to the significant increase in profit before tax in 2010.

Other income, net, including exchange gains or losses. Our other income, net, including exchange gains or

losses was RMB44.2 million (US$6.7 million) in 2010, compared to RMB45.8 million in 2009.

Net Income. As a result of the foregoing, we had net income of RMB3.5 billion (US$534.1 million) in 2010,

a 137.4% increase from RMB1.5 billion in 2009.

Year Ended December 31, 2009 Compared to Year Ended December 31, 2008

Revenues. Our total revenues increased by 39.1% from RMB3.2 billion in 2008 to RMB4.4 billion in 2009.
This increase was primarily due to a substantial increase in our revenues from online marketing services. Our online
marketing revenues increased by 39.2% from RMB3.2 billion in 2008 to RMB4.4 billion in 2009. This increase was
mainly attributable to the increase in the number of our online marketing customers from approximately 284,000 in
2008 to over 317,000 in 2009, and the increase in the average revenue per customer from approximately
RMB11,200 in 2008 to approximately RMB14,000 in 2009. The increase in our online marketing customers
was mainly due to our effective distribution network and our expanded direct sales, especially in Beijing, Shanghai,
Guangzhou, Shenzhen and Dongguan. The increase in the average revenue per customer was primarily attributable
to the increase in the number of paid clicks and the higher price per click as more customers participated in our P4P
auction platform. The number of paid clicks increased by approximately 16.9% from 2008 to 2009.

Operating Costs and Expenses. Our total operating costs and expenses increased by 35.3% from
RMB2.1 billion in 2008 to RMB2.8 billion in 2009. This increase was primarily due to the expansion of our
business.

(cid:129) Cost of Revenues. Our cost of revenues increased by 39.9% from RMB1.2 billion in 2008 to

RMB1.6 billion in 2009. This increase was primarily due to the following factors:

(cid:129) Traffic Acquisition Costs. Our traffic acquisition costs increased by 66.7% from RMB418.5 million in
2008 to RMB697.7 million in 2009. This was primarily due to the growth of revenue contribution from our
Baidu Union members.

(cid:129) Bandwidth Costs and Depreciation Expenses. Our bandwidth costs increased by 14.1% from
RMB178.7 million in 2008 to RMB203.9 million in 2009. Our depreciation expenses of servers and
other equipment increased by 11.1% from RMB225.8 million in 2008 to RMB251.0 million in 2009. The
absolute increases in these costs were due to the expansion of our business. However, these costs in 2009
accounted for a lower percentage of total revenues than in 2008. The decreases in bandwidth costs and
depreciation expenses as percentages of total revenues reflect our improved efficiency as well as the
scalability of our Internet-based business model;

(cid:129) Business Tax and Surcharges. Our business tax and surcharges increased by 37.9% from
RMB200.1 million in 2008 to RMB275.9 million in 2009, primarily as a result of increase in our
online marketing revenues; and

(cid:129) Operational Costs. Our operational costs increased by 41.8% from RMB127.9 million in 2008 to
RMB181.4 million in 2009, primarily due to the increase in the number and compensation levels of our
operating and technical support employees to meet the needs of our growing operations.

(cid:129) Selling, General and Administrative Expenses. Our selling, general and administrative expenses increased
by 21.9% from RMB659.8 million in 2008 to RMB804.0 million in 2009. This increase was primarily due to
the following factors:

(cid:129) total salaries and benefits and staff-related expenses increased by 13.1% from RMB353.8 million in 2008
to RMB400.3 million in 2009, primarily due to the increased direct sales headcount to support our
expanded online marketing services;

(cid:129) total office operating expenses increased by 10.8% from RMB77.2 million in 2008 to RMB85.5 million in

2009, primarily as a result of increase and expansion of our direct sales offices;

71

(cid:129) total

traveling, communication and business development expenses increased by 28.9% from
RMB23.9 million in 2008 to RMB30.8 million in 2009, primarily due to the increased direct sales
headcount and activities to support our expanded online marketing services; and

(cid:129) marketing and promotion expenses increased by 75.3% from RMB90.7 million in 2008 to

RMB159.0 million in 2009 primarily due to the increased marketing and promotion activities.

The above increases were partially offset by a 7.2% decrease in share-based compensation expenses
allocated to selling, general and administrative expenses from RMB41.7 million in 2008 to
RMB38.7 million in 2009, primarily due to the maturity of some share-based awards granted in prior
years.

(cid:129) Research and Development Expenses. Our research and development expenses increased by 47.6% from
RMB286.3 million in 2008 to RMB422.6 million in 2009, primarily due to an increase in the number and
compensation levels of research and development staff.

Operating Profit. As a result of the foregoing, we generated an operating profit of RMB1.6 billion in 2009, a

46.3% increase from 2008.

Taxation. Our

income tax expenses increased by 70.6% from RMB116.1 million in 2008 to

RMB198.0 million in 2009, primarily due to the expiration of tax holiday of our subsidiary Baidu Times.

Other income, net, including exchange gains or losses. Our other income, net, including exchange gains or
losses was RMB45.8 million in 2009, compared to RMB19.8 million in 2008. The increase was primarily due to
more government subsidies received in 2009.

Net Income. As a result of the foregoing, we had net income of RMB1.5 billion in 2009, a 41.7% increase

from RMB1.0 billion in 2008.

Inflation

Inflation in China has not materially impacted our results of operations. According to the National Bureau of
Statistics of China, the annual average percent changes in the consumer price index in China for 2008, 2009 and
2010 were an increase of 5.9%, a decrease of 0.7% and an increase of 3.3%, respectively. The year-over-year
percent changes in the consumer price index for January 2009, 2010 and 2011 were increases of 1.0%, 1.5% and
4.9%, respectively. Although we have not been materially affected by inflation in the past, we can provide no
assurance that we will not be affected in the future by higher rates of inflation in China. For example, certain
operating costs and expenses, such as employee compensation and office operating expenses may increase as a
result of higher inflation. Additionally, because a substantial portion of our assets consists of cash and cash
equivalents and short-term investments, high inflation could significantly reduce the value and purchasing power of
these assets. We are not able to hedge our exposure to higher inflation in China.

Foreign Currency

The average exchange rate between U.S. dollar and RMB has declined from RMB8.2264 per U.S. dollar in
July 2005 to RMB6.6497 per U.S. dollar in December 2010. The functional currency of our subsidiaries in Japan is
the Japanese yen appreciated by
the Japanese yen, and their reporting currency is RMB. During 2010,
approximately 10.2% against RMB. As of December 31, 2010, we recorded RMB117.4 million
(US$17.8 million) of net foreign currency translation loss in accumulated other comprehensive loss as a
component of shareholders’ equity. We have not hedged exposures to exchange fluctuations using any hedging
instruments. See also “Item 3.D. Key Information — Risk Factors — Risks Related to Doing Business in China —
Fluctuation in the value of the RMB may have a material adverse effect on your investment.” and “Item 11.
Quantitative and Qualitative Disclosures About Market Risk — Foreign Exchange Risk.”

Critical Accounting Policies

We prepare financial statements in accordance with U.S. GAAP, which requires us to make judgments,
estimates and assumptions that affect the reported amounts of our assets and liabilities and the disclosure of our

72

contingent assets and liabilities at the end of each fiscal period and the reported amounts of revenues and expenses
during each fiscal period. We continually evaluate these judgments and estimates based on our own historical
experience, knowledge and assessment of current business and other conditions, our expectations regarding the
future based on available information and assumptions that we believe to be reasonable, which together form our
basis for making judgments about matters that are not readily apparent from other sources. Since the use of
estimates is an integral component of the financial reporting process, our actual results could differ from those
estimates. Some of our accounting policies require a higher degree of judgment than others in their application.

The selection of critical accounting policies, the judgments and other uncertainties affecting application of
those policies and the sensitivity of reported results to changes in conditions and assumptions are factors that should
be considered when reviewing our financial statements. For further information on our significant accounting
policies, see Note 2 to our consolidated financial statements. We believe the following accounting policies involve
the most significant judgments and estimates used in the preparation of our financial statements.

Revenue Recognition

We recognize revenues based on the following principles:

Online marketing services

(1) Auction-based pay-for-performance service

Our auction-based pay-for-performance (“P4P”) platform enables a customer to place its website link and
related description on our search result list. The customers make bids on keywords based on how much they are
willing to pay for each click to their listings in the search results listed on the our website and the relevance between
the keywords and the customer’s businesses. Internet users’ search of the keyword will trigger the display of the
listings. The ranking of the customer’s listing depends on both the bidding price and the listing’s relevance to the
keyword searched. Customer pays us only when a user clicks on one of its website links. Revenue is recognized
when a user clicks on one of the customer-sponsored website links, as there is persuasive evidence of an
arrangement, the fee is fixed or determinable and collection is reasonably assured, as prescribed by ASC
subtopic 605-10 (“ASC 605-10”), Revenue Recognition: Overall.

For certain P4P customers engaged through direct sales, we may provide certain value-added consultative
support services to help its customers to better utilize its P4P online marketing system. Fees for such services are
recognized as revenue on a pro-rata basis over the contracted service period.

(2) Other performance-based online marketing services

To the extent we provide online marketing services based on performance criteria other than click-throughs,
such as the number of telephone calls brought to our customers, the number of users registered with our customers,
or the number of minimum click-throughs, revenue is recognized when the specified performance criteria are met
together with satisfaction of other applicable revenue recognition criteria as prescribed by ASC 605-10.

(3) Time-based online advertising services

For time-based online advertising services such as text

links, banners, or other forms of graphical
advertisements, we recognize revenue,
in accordance with ASC 605-10, on a pro-rata basis over the
contractual term commencing on the date the customer’s advertisement is displayed in a specified webpage.
For certain time-based contractual agreements, we may also provide certain performance guarantees, in which cases
revenue is recognized at the later of the completion of the time commitment or performance guarantee.

(4) Online marketing services involving Baidu Union

Baidu Union is the program through which we expand distribution of our customers’ sponsored links or
advertisements by leveraging traffic of the Baidu Union members’ Internet properties. We make payments to Baidu
Union members for acquisition of traffic. We recognize gross revenue for the amount of fees we receive from our
customers. Payments made to Baidu Union members are included in cost of revenues as traffic acquisition costs.

73

(5) Barter transactions

We engages in barter transactions from time to time and in such situations follows the guidance set forth in
ASC subtopic 845-10 (“ASC 845-10”), Nonmonetary Transactions: Overall. While nonmonetary transactions are
generally recorded at fair value, if such value is not determinable within reasonable limits, the transaction is
recognized based on the carrying value of the product or services provided. The amount of revenues recognized for
barter transactions was insignificant for each of the periods presented.

In addition, we recognized revenues for barter transactions involving advertising in accordance with ASC
subtopic 605-20 (“ASC 605-20”), Revenue recognition: Services. However, neither the amount recognized nor the
volume of such transactions qualified for income recognition was material for any of the periods presented.

In certain instances, we may be granted equity instruments in exchange for services. In accordance with ASC
subtopic 505-50 (“ASC 505-50”), Equity: Equity-based Payments to Non-Employees, if we provide services in
exchange for equity instruments, we measure the fair value of those equity instruments for revenue recognition
purposes as of the earlier of either of the following dates:

(cid:129) The date the parties come to a mutual understanding of the terms of the equity-based compensation

arrangement and a commitment for performance by us to earn the equity instruments is reached;

(cid:129) The date at which our performance necessary to earn the equity instruments is completed.

If, as of the measurement date, the fair value of the equity instruments received is not determinable within
reasonable limits, the transaction is recognized based on the fair value of the services provided. If the fair value of
both the equity instruments received and the services provided cannot be determined, no revenue is recognized for
the services provided and the equity instrument received is recorded at zero carrying value. The amount of revenues
recognized for such transactions was insignificant in each of the years presented.

(6) Other revenue recognition related policies

If a sales arrangement involves multiple deliverables, and the arrangement is divided into separate units of
accounting in accordance with ASC subtopic 605-25 (“ASC 605-25”), Revenue recognition: Multiple-Element
Arrangements, the total revenue on such arrangement is allocated to the individual deliverables based on their
relative fair values. If sufficient vendor-specific objective evidence of fair value does not exist for the allocation of
revenue, the fee for the entire arrangement is recognized ratably over the term of the arrangement or upon the
delivery of the last deliverable, when other revenue recognition criteria have been met.

We deliver some of our online marketing services to end customers through engaging third party distributors.
In this context, we may provide cash incentives to distributors. The cash incentives are accounted for as reduction of
revenue in accordance with ASC subtopic 605-50 (“ASC 605-50”), Revenue recognition: Customer Payments and
Incentives.

We provide sales incentives to entitle customers, who meet certain accumulative consumption requirements, to
receive price reduction in the online marketing services. The Company accounts for these award credits granted to
members in conjunction with a current sale of products or services as a multiple-element arrangement by
analogizing to ASC 605-25. The consideration allocated to the award credits, as deferred revenue, is based on
an assumption that the customer will purchase the minimum amount of future service necessary to obtain the
maximum award credits available. The deferred revenue is recognized as revenue proportionately as the future
services are delivered to the customer or when the loyalty points expire.

Cash received in advance from customers is recorded as customer advances and deposits. The unused cash
balances remaining in customers’ accounts are included as our liability. Deferred revenue is recorded when services
are provided before the other revenue recognition criteria set forth in ASC 605-10 are fulfilled.

We operate an online game platform, on which registered users can access games provided by online-game
developers. The rights and obligations set out in the arrangement between the online-game developer and us
indicate that we are an agent whereas the online-game developers are the principal for being the primary obligors in
the arrangement. As a result, we recognize the shared revenue on a net basis, based on the ratios pre-determined

74

with the online game developers when all the revenue recognition criteria set forth in ASC 605-10 are met, which is
generally when users purchase virtual currencies issued by the game developers through our payment channel. The
revenues recognized were not significant in each of the years presented.

Share-based Compensation

We account for share-based compensation in accordance with ASC subtopic 718-10, or ASC 718-10,
Compensation-Stock Compensation: Overall. Under the provisions of ASC 718-10, share-based compensation
cost is estimated at the grant date based on the award’s fair value as calculated by the Black-Scholes-Merton (BSM)
option-pricing model and is recognized as expense over the requisite service period. The BSM model requires
various highly judgmental assumptions including volatility and expected option life. Volatility is measured using
historical daily price changes of our ADSs over the respective expected life of the option. Expected option life is the
number of years that we estimate, based on the vesting and contractual terms and employee demographics. If any of
the assumptions used in the BSM model change significantly, share-based compensation expenses may differ
materially in the future from that recorded in the current period.

In addition, we are required to estimate the expected forfeiture rate and only recognize expense for those shares
expected to vest. We estimate the forfeiture rate based on historical experience. Further, to the extent our actual
forfeiture rate is different from our estimate, stock-based compensation expense is adjusted accordingly.

Income Taxes

We are subject to income taxes in the PRC and Japan. Significant judgment is required in evaluating our

uncertain tax positions and determining our provision for income taxes.

ASC subtopic 740-10, or ASC 740-10, Income Taxes: Overall, contains a two-step approach to recognizing
and measuring uncertain tax positions accounted for in accordance with ASC 740-10. The first step is to evaluate the
tax position for recognition by determining if the weight of available evidence indicates that it is more likely than
not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any.
The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized
upon settlement.

We make assumptions, judgments and estimates in the recognition and measurement of a tax position taken or
expected to be taken in a tax return. These judgments, assumptions and estimates take into account current tax laws,
our interpretation of current tax laws and possible outcomes of current and future audits conducted by foreign and
domestic tax authorities. Changes in tax law or our interpretation of tax laws and the resolution of current and future
tax audits could significantly impact the amounts of unrecognized, uncertain tax positions, if any, provided or to be
provided for in our consolidated financial statements. Although we believe we have adequately reserved for our
uncertain tax positions, no assurance can be given that the final tax outcome of these matters will not be different. In
general, PRC and Japanese tax authorities have up to five and seven years, respectively, to conduct examination on
our tax filings. Accordingly, our PRC subsidiaries’ and affiliated entities’ tax filings for the tax years 2007 to 2010
and our Japanese subsidiary’s tax filings for the tax years 2007 to 2010 remain open to examination by the
respective taxing jurisdictions.

Our assumptions, judgments and estimates relative to the value of a deferred tax asset take into account
predictions of the amount and category of future taxable income, such as income from operations. Actual operating
results and the underlying amount and category of income in future years could render our current assumptions,
judgments and estimates of recoverable net deferred taxes inaccurate. Any of the assumptions, judgments and
estimates mentioned above could cause our actual income tax obligations to differ from our estimates, and thus
materially impact our financial position and results of operations. We do not believe that net deferred tax assets
related with our Japan operations are more likely than not to be realized. Consequently, we have provided full
valuation allowances on the related net deferred tax assets.

75

Allowance for Doubtful Accounts

Accounts receivable are recognized and carried at original invoiced amount less an allowance for any potential
uncollectible amounts. An estimate for doubtful debts is made when collection of the full amount is no longer
probable. Bad debts are written off as incurred. We generally do not require collateral from our customers.

We maintain allowances for doubtful accounts for estimated losses resulting from the failure of customers to
make payments on time. We review the accounts receivable on a periodic basis and make general and specific
allowances when there is doubt as to the collectibility of individual balances. In evaluating the collectibility of
individual receivable balances, we consider many factors, including the age of the balance, the customer’s past
payment history, its current credit-worthiness and current economic trends. If the financial condition of our
customers were to deteriorate, resulting in an impairment of their ability to make payments, or if the operators
decide not to pay us, additional allowances may be required which could materially impact our financial position
and results of operations.

Impairment of Long-Lived Assets

We evaluate long-lived assets, such as property and equipment and purchased or internally developed
intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate the
carrying value of an asset may not be recoverable in accordance with ASC subtopic 360-10, Property, Plant and
Equipment: Overall. We assess the recoverability of an asset group based on the undiscounted future cash flows the
asset group is expected to generate and recognize an impairment loss when the estimated undiscounted future cash
flows expected to result from the use of the asset group plus net proceeds expected from the disposition of the asset
group, if any, are less than the carrying value of the asset group. If we identify an impairment, we reduce the carrying
amount of the asset group to its estimated fair value based on a discounted cash flow approach or, when available
and appropriate, to comparable market values. We use estimates and judgments in our impairment tests and if
different estimates or judgments had been utilized, the timing or the amount of any impairment charges could be
different.

Impairment of Goodwill and Intangible Assets with Indefinite Life

We assess goodwill and non-amortized intangible assets for impairment in accordance with ASC subtopic
350-20, or ASC 350-20, Intangibles — Goodwill and Other: Goodwill, which requires that goodwill and
non-amortized intangible assets be tested for impairment at the “reporting unit level” at least annually and
more frequently upon the occurrence of certain events, as defined by ASC 350-20. Intangible assets with an
indefinite useful life are not amortized. In accordance with this policy, one of the domain name assets, which was
acquired in July 2006, and the “Baidu” trademark are not subject to amortization, as the remaining useful life is
indefinite. Based on our business activities and operational management perspective, we have determined that there
is only one reporting unit. Goodwill and non-amortized intangible assets were tested for impairment in the annual
impairment tests on December 31 in each of the years 2008, 2009 and 2010 using the two-step process required by
ASC 350-20. First, we reviewed the carrying amount of the reporting unit compared to the “fair value” of the
reporting unit based on quoted market prices of our ordinary shares. If such comparison reflected potential
impairment, we would then prepare the discounted cash flow analyses. Such analyses are based on cash flow
assumptions that are consistent with the plans and estimates being used to manage the business. Cash flow
assumptions include estimating future cash flows, determining appropriate discount rates and making other
assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value for
the reporting unit. An excess of the carrying value of the goodwill over the fair value of the goodwill would indicate
that the goodwill may be impaired. Finally, if we determined that goodwill may be impaired, the “implied fair
value” of the goodwill, as defined by ASC 350-20, would be compared to its carrying amount to determine the
impairment loss, if any. There has been no impairment of goodwill in any of the years presented.

Impairment of Long-term Investments

Our

long-term investments consist of cost method investments, equity method investments and

available-for-sale securities. Our long-term investments primarily focus on the privately-held companies.

76

We periodically review our cost method investments and equity method investments for impairment. If we
conclude that any of
is
such investments are impaired, we will assess whether
other-than-temporary. Factors we consider to make such determination include the performance and financial
position of the investee as well as other evidence of market value. 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 financing needs. If any impairment is considered other-than-temporary, an impairment loss is
recognized in the consolidated statements of income equal to the excess of the investment’s cost over its fair value at
the balance sheet date of the reporting period for which the assessment is made.

such impairment

Our

long-term investments in available-for-sale securities are the debt security investments. Our
available-for-sale debt securities are reported at fair value, and we do not intend to sell the security and it is
not more likely than not that we will be required to sell the securities before recovery of their amortized cost basis
less any current-period credit loss. If we determine a decline in fair value is other-than-temporary, the amount of the
total other-than-temporary impairment related to the credit loss shall be recognized in earnings and the amount of
the total other-than-temporary impairment related to other factors shall be recognized in other comprehensive
income, net of applicable taxes. The previous amortized cost basis less the other-than-temporary impairment
recognized in earnings shall become the new amortized basis of the investment. That new amortized cost basis shall
not be adjusted for subsequent recoveries in fair value.

The fair value determination, particularly for investments in privately-held companies, requires significant
judgment to determine appropriate estimates and assumptions. Changes in these estimates and assumptions could
affect the calculation of the fair value of the investments and the determination of whether any identified
impairment is other-than-temporary.

Recent Accounting Pronouncements

In October 2009, the FASB issued ASU No. 2009-13 (“ASU 2009-13”), Multiple-Deliverable Revenue
Arrangements. ASU 2009-13 amends ASC sub-topic 605-25 (“ASC 605-25”), Revenue Recognition: Multiple-
Element Arrangements, regarding revenue arrangements with multiple deliverables. This standard addresses how to
determine whether an arrangement involving multiple deliverables contains more than one unit of accounting, and
how the arrangement consideration should be allocated among the separate units of accounting. This standard
establishes a selling price hierarchy for determining the selling price of a deliverable, which is based on: (a) vendor-
specific objective evidence; (b) third-party evidence; or (c) estimated selling price. This standard also eliminates the
residual method of allocation and requires that arrangement consideration be allocated at the inception of the
arrangement to all deliverables using the relative selling price method. This standard makes clear that the objective
of determining the best estimate of selling price is to identify the price at which the entity would transact if the
deliverable were sold on a standalone basis. In making this estimate, entities should consider all reasonably
available information, including both market data and conditions and entity-specific factors, when estimating the
selling price. Changes in these estimates and assumptions could affect the determination of the best estimate of
selling price of a deliverable and the amount of revenue recognized. In addition, this standard significantly expands
required disclosures related to a vendor’s multiple-deliverable revenue arrangements. This standard is effective for
fiscal years beginning after June 15, 2010 and to be applied retrospectively or prospectively for new or materially
modified arrangements. In addition, early adoption is permitted. We will adopt ASU 2009-13 beginning January 1,
2011 and we are in the process of assessing the impact of the adoption of the standard on its consolidated financial
statements.

In April 2010, the FASB issued ASU No. 2010-13 (“ASU 2010-13”), Compensation-Stock Compensation
(ASC 718): Effect of Denominating the Exercise Price of a Share-Based Payment Award in the Currency of the
Market in Which the Underlying Equity Security Trades. The objective of this standard is to address the
classification of an employee share-based payment award with an exercise price dominated in the currency of
a market in which the underlying equity security trades. ASC 718 provides guidance on the classification of a share-
based payment award as either equity or liability. A share-based payment award that contains a condition that is not
a market, performance, or service condition is required to be classified as a liability. ASU 2010-13 provides
amendments to clarify that an employee share-based payment award with an exercise price denominated in the
currency of a market in which a substantial portion of the entity’s equity securities trades should not be considered

77

to contain a condition that is not a market, performance, or service condition. Therefore, an entity would not classify
such an award as a liability if it otherwise qualifies as equity. The amendments in this standard are effective for fiscal
years, and interim periods within those fiscal years, beginning on or after December 31, 2010. Early application is
permitted. We do not expect the adoption of ASU 2010-13 will have a material impact on our consolidated financial
statements.

In December 2010, the FASB issued ASU No. 2010-28 (“ASU 2010-28”), Intangibles — Goodwill and Other
(ASC 350): When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative
Carrying Amounts. The objective of this standard is to address questions about entities with reporting units with
zero or negative carrying amounts because some entities concluded that Step 1 of the test is passed in those
circumstances because the fair value of their reporting unit will generally are greater than zero. The amendments in
this standard modify Step 1 of the goodwill impairment test for reporting units with zero or negative carrying
amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is
more likely than not that a goodwill impairment exists. This standard is effective for fiscal years, and interim periods
within those years, beginning after December 15, 2010. Early adoption is not permitted. We do not expect the
adoption of ASU 2010-28 will have a material impact on our consolidated financial statements.

In December 2010, the FASB issued ASU No. 2010-29 (“ASU 2010-29”), Disclosure of Supplementary Pro
Forma Information for Business Combinations (“ASC 805”). The objective of this standard is to address diversity in
practice about the interpretation of the pro forma revenue and earnings disclosure requirements for business
combinations. This standard specifies that if a public entity presents comparative financial statements, the entity
should disclose revenue and earnings of the combined entity as though the business combination(s) that occurred
during the current year had occurred as of the beginning of the comparable prior annual reporting period only. This
standard also expands the supplemental pro forma disclosures under ASC 805 to include a description of the nature
and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination
included in the reported pro forma revenue and earnings. This standard is effective prospectively for business
combinations for which the acquisition date is on or after the beginning of the first annual reporting period
beginning on or after December 15, 2010. Early adoption is permitted. We do not expect the adoption of ASU
2010-29 will have a material impact on our consolidated financial statements.

B. Liquidity and Capital Resources

Our principal sources of liquidity are our cash, cash equivalents and short-term investments, which comprise
primarily of fixed rate investments maturing within one year, as well as the cash flow generated from our operations.
We believe that our current cash, cash equivalents, short-term investments and anticipated cash flow from
operations will be sufficient to meet our anticipated cash needs, including our cash needs for working capital
and capital expenditures, for at least the next 12 months. We may, however, require additional cash due to changing
business conditions or other future developments, including any investments or acquisitions we may decide to
pursue. If our existing cash is insufficient to meet our requirements, we may seek to sell additional equity securities,
debt securities or borrow from banks.

Operating Activities

Net cash generated from operating activities increased to RMB4.7 billion (US$712.2 million) in 2010 from
RMB2.3 billion in 2009. This increase was mainly attributable to several factors, including (i) the substantial
increase in net income to RMB3.5 billion (US$534.1 million) in 2010 from RMB1.5 billion in 2009; (ii) the
increase in add-back of non-cash expenses, mainly consisting of depreciation expenses; and (iii) the increases in
customer advance, deferred revenues and accounts payable.

Net cash generated from operating activities increased to RMB2.3 billion in 2009 from RMB1.7 billion in
2008. This increase was mainly attributable to several factors, including (i) the substantial increase in net income to
RMB1.5 billion in 2009 compared to net income of RMB1.0 billion in 2008; (ii) the increase in add-back of non-
cash expenses, mainly consisting of share-based compensation and depreciation expenses; and (iii) the increases in
customer advance, deferred revenues and accounts payable.

Investing Activities

Net cash used in investing activities increased from RMB536.1 million in 2009 to RMB1.2 billion

(US$184.5 million) in 2010, primarily due to the acquisition of fixed assets and long-term investments.

Net cash used in investing activities decreased from RMB661.1 million in 2008 to RMB536.1 million in 2009,

primarily due to less spending on acquisition of fixed assets and construction of Baidu Campus.

Financing Activities

Net cash flow generated from financing activities was RMB124.8 million (US$18.9 million) in 2010,
compared to a net cash flow of RMB95.1 million generated from financing activities in 2009, primarily due to
the increase in proceeds from the long-term lines of credit.

Net cash flow generated from financing activities was RMB95.1 million in 2009, compared to a net cash flow
used in financing activities in 2008, primarily due to the receipt of cash payments previously made by us,

plus pre-determined premiums, in two structured share repurchase transactions in 2009.

We are a holding company with no operations of our own. We conduct our operations in China primarily
through our indirect wholly owned subsidiaries and our consolidated affiliated entities in China. As a result, our
ability to pay dividends and to finance any debt we may incur depends upon dividends paid by our PRC subsidiaries
and license and service fees paid by our PRC consolidated affiliated entities. If any of our subsidiaries incurs debt on
its own behalf in the future, the instruments governing such debt may restrict its ability to pay dividends to us. In
addition, our PRC subsidiaries are permitted to pay dividends to us only out of their retained earnings, if any, as

79

determined in accordance with PRC accounting standards and regulations. Under PRC law, our subsidiaries and
consolidated affiliated entities in the PRC are required to set aside at least 10% of their after-tax profit each year to
fund a statutory reserve fund until the amount of the reserve fund reaches 50% of such entity’s registered capital.
Although these statutory reserve funds can be used, among other ways, to increase the registered capital and
eliminate future losses in excess of retained earnings of the respective companies, these reserve funds are not
distributable as cash dividends except in the event of a solvent liquidation of the companies. See Note 13 to our
consolidated financial statements.

Capital Expenditures

We made capital expenditures of RMB417.9 million, RMB399.3 million, and RMB895.3 million
(US$135.7 million) in 2008, 2009 and 2010, respectively, representing 13.1%, 9.0% and 11.3% of our total
revenues, respectively. In 2010, our capital expenditures were used primarily to purchase servers, network
equipment and other computer hardware for our business. We funded our capital expenditures primarily with
net cash flow generated from operating activities.

In late 2005, we entered into an agreement to acquire the land use right in Beijing to build our new corporate
headquarters. We made a total payment of RMB97.6 million for the land use right. The construction and renovation
of our new corporate headquarters were completed in 2009, and we moved into the new building in November 2009.
Our capital expenditures in connection with the construction and renovation of our new office building were
RMB172.3 million in 2008, RMB209.2 million in 2009 and RMB38.7 million (US$5.9 million) in 2010, excluding
payment for the land use right. Our capital expenditures may increase substantially in the near term as our business
continues to grow and as we expand and improve our network infrastructure.

C. Research and Development

We have a team of experienced engineers who are mostly based at our headquarters in Beijing. We recruit most
of our engineers locally and have established various recruiting and training programs with leading universities in
China. We have also recruited experienced engineers from overseas. We compete aggressively for engineering
talent to help us address challenges such as Chinese language processing, information retrieval and high
performance computing. In each of the three years ended December 31, 2008, 2009 and 2010, our research
and development expenditures, including share-based compensation expenses for research and development staff,
were RMB286.3 million, RMB422.6 million and RMB718.0 million (US$108.8 million), representing 9.0%, 9.5%
and 9.1% of our total revenues for 2008, 2009 and 2010, respectively.

D. Trend Information

Other than as disclosed elsewhere in this annual report, we are not aware of any trends, uncertainties, demands,
commitments or events for the year ended December 31, 2010 that are reasonably likely to have a material adverse
effect on our net revenues, income, profitability, liquidity or capital resources, or that would cause the disclosed
financial information to be not necessarily indicative of future operating results or financial conditions.

E. Off-Balance Sheet Arrangements

We have not entered into any financial guarantees or other commitments to guarantee the payment obligations
of any third parties. We have not entered into any off-balance sheet derivative instruments. Furthermore, we do not
have any retained or contingent interest in assets transferred to an unconsolidated entity that serves as credit,
liquidity or market risk support to such entity. We do not have any variable interest in any unconsolidated entity that
provides financing, liquidity, market risk or credit support to us or engages in leasing, hedging or research and
development services with us.

The following paragraphs summarize the key terms of our 2000 option plan, which was amended and restated

on December 16, 2008, and our 2008 share incentive plan.

2000 Option Plan

Types of Awards. We may grant the following types of awards under our 2000 option plan:

(cid:129) our ordinary shares;

(cid:129) options to purchase our ordinary shares; and

(cid:129) any other securities with value derived from the value of our ordinary shares.

Plan Administration. Our board of directors, or a committee designated by our board of directors,
administers our 2000 option plan. In each case, our board of directors or the committee, will determine the
provisions and terms and conditions of each award grant. These include, among other things, the option vesting
schedule, repurchase provisions, rights of first refusal, forfeiture provisions, form of payment upon settlement of an
award, payment contingencies and satisfaction of any performance criteria.

Award Agreement. Awards granted under our 2000 option plan are evidenced by an award agreement that
sets forth the terms, conditions and limitations for each award. In addition, in the case of options, the award
agreement also specifies whether the option constitutes an incentive stock option, or ISO, or a non-qualifying stock
option.

Eligibility. We may grant awards to employees, directors and consultants of our company or any of our
related entities, which include our subsidiaries or any entities in which we hold a substantial ownership interest.
However, we may grant ISOs only to our employees and employees of our majority-owned subsidiaries.

Acceleration of Awards upon Corporate Transactions. The outstanding awards will accelerate upon
occurrence of a change-of-control corporate transaction in which the successor entity does not assume our
outstanding awards under our 2000 option plan. In such event, each outstanding award will become fully vested and
immediately exercisable, the transfer restrictions on the awards will be released (other than those applicable to
ISOs), and the repurchase or forfeiture rights will terminate immediately before the date of the change-of-control
transaction. If the successor entity assumes our outstanding awards and later terminates the grantee’s employment
or service without cause, or if the grantee resigns voluntarily with good cause within 12 months of the
change-of-control transaction, the outstanding awards automatically become fully vested and exercisable.

Exercise Price and Term of Awards.

If we grant an ISO to an employee, who, at the time of that grant, owns
shares representing more than 10% of the voting power of all classes of our share capital, the exercise price cannot
be less than 110% of the fair market value of our ordinary shares on the date of that grant. To the extent not
prohibited by applicable law or exchange rules, a downward adjustment of the exercise price per share subject to an
outstanding option may be made in the absolute discretion of the plan administrator without the approval of our
shareholders or the affected grantees.

The term of each award is stated in the award agreement. The term may not exceed ten years from the date of
the grant, except that five years is the maximum term of an ISO granted to an employee who holds more than 10% of
the voting power of our share capital.

Vesting Schedule.

In general, the plan administrator determines, or the award agreement specifies, the
vesting schedule. Options generally vest over a four-year period beginning from one year after the grant date. The
award agreements may provide that grantees may elect at any time during their employment or service to exercise
any part or all of the awards prior to full vesting of the awards. But such early exercise may be subject to a
repurchase right as determined by the plan administrator. When an optionee’s employment or service is terminated,
the optionee may exercise his or her options that have vested as of the termination date within three months of
termination or as determined by our plan administrator.

Repurchase Rights.

If an award agreement provides for repurchase rights upon termination of a grantee’s
employment or service, it must (or may, with respect to awards granted to officers, directors or consultants) provide
that (i) such repurchase right must be exercised within 90 days of termination of the grantee’s employment or

84

service (or, in the case of exercise of awards after termination of the grantee’s employment or service, within
90 days following such exercise), (ii) the repurchase price must be equal to the original purchase price paid by the
grantee for each such share, and (iii) the right to repurchase will lapse at the rate of at least 20% of the shares subject
to the award per year over five years from the date the award is granted (without respect to the date the award was
exercised or became exercisable).

Amendment and Termination. Our board of directors may at any time amend, suspend or terminate our 2000
option plan. Amendments to our 2000 option plan are subject to shareholder approval, to the extent required by law,
or by stock exchange rules or regulations. Any amendment, suspension or termination of our 2000 option plan must
not adversely affect awards already granted without written consent of the recipient of such awards. Unless
terminated earlier, our 2000 option plan shall continue in effect for a term of ten years from the date of adoption.

2008 Share Incentive Plan

Types of Awards. We may grant the following types of awards under our 2008 share incentive plan:

(cid:129) options;

(cid:129) restricted shares;

(cid:129) restricted share units; and

(cid:129) any other form of award granted to a participant pursuant to the 2008 plan.

Plan Administration. The compensation committee of our board of directors administers our 2008 share
incentive plan, but may delegate to a committee of one or more members of our board of directors the authority to
grant or amend awards to participants other than independent directors and executive officers. The compensation
committee will determine the provisions and terms and conditions of each award grant, including, but not limited to,
the exercise price, the grant price or purchase price, any restrictions or limitations on the award, any schedule for
lapse of forfeiture restrictions or restrictions on the exercisability of an award, and accelerations or waivers thereof,
any provisions related to non-competition and recapture of gain on an award, based in each case on such
considerations as the committee in its sole discretion determines. The compensation committee has the sole
power and discretion to cancel, forfeit or surrender an outstanding award (whether or not in exchange for another
award or combination or awards).

Award Agreement. Awards granted under our 2008 share incentive plan are evidenced by an award
agreement that sets forth the terms, conditions and limitations for each award which may include the term of
an award, the provisions applicable in the event the participant’s employment or service ends, and our authority to
unilaterally or bilaterally amend, modify, suspend, cancel or rescind an award.

Eligibility. We may grant awards to employees, directors and consultants of our company or any of our
related entities, which include our subsidiaries or any entities in which we hold a substantial ownership interest.
However, we may grant ISOs only to our employees and employees of our majority-owned subsidiaries.

Acceleration of Awards upon Corporate Transactions. The outstanding awards will accelerate upon
occurrence of a change-of-control corporate transaction in which the successor entity does not assume our
outstanding awards under our 2008 share incentive plan, provided that the plan participant remains an employee,
consultant or member of our board of directors on the effective date of the corporate transaction. In such event, each
outstanding award will become fully exercisable and all forfeiture restrictions on such award will lapse immediately
prior to the specified effective date of the corporate transaction.

If the successor entity assumes our outstanding awards and later terminates the grantee’s employment or
service without cause, or if the grantee resigns voluntarily with good reason within 12 months of the corporate
transaction, the outstanding awards automatically will become fully vested and exercisable. The compensation
committee may also, in its sole discretion, upon or in anticipation of a corporate transaction, accelerate awards,
purchase the awards from the plan participants, replace the awards, or provide for the payment of the awards in cash.

Exercise Price and Term of Awards. The exercise price per share subject to an option may be amended or
adjusted in the absolute discretion of the compensation committee, the determination of which shall be final,

85

binding and conclusive. To the extent not prohibited by applicable laws or exchange rules, a downward adjustment
of the exercise prices of options mentioned in the preceding sentence shall be effective without the approval of our
shareholders or the approval of the affected grantees. If we grant an ISO to an employee, who, at the time of that
grant, owns shares representing more than 10% of the voting power of all classes of our share capital, the exercise
price cannot be less than 110% of the fair market value of our ordinary shares on the date of that grant. The
compensation committee will determine the time or times at which an option may be exercised in whole or in part,
including exercise prior to vesting. The term may not exceed ten years from the date of the grant, except that five
years is the maximum term of an ISO granted to an employee who holds more than 10% of the voting power of our
share capital.

Restricted Shares and Restricted Share Unites. The compensation committee is also authorized to make
awards of restricted shares and restricted share units. Except as otherwise determined by the compensation
committee at the time of the grant of an award or thereafter, upon termination of employment or service during the
applicable restriction period, restricted shares that are at the time subject to restrictions shall be forfeited or
repurchased in accordance with the respective award agreements. At the time of grant for restricted share units, the
compensation committee shall specify the date on which the restricted share units shall become fully vested and
nonforfeitable, and may specify such conditions to vesting as it deems appropriate.

Amendment and Termination. With the approval of our board of directors, the compensation committee may
at any time amend, suspend or terminate our 2008 share incentive plan. Amendments to our 2008 share incentive
plan are subject to shareholder approval, to the extent required by law, or by stock exchange rules or regulations.
Any amendment, suspension or termination of our 2008 share incentive plan must not adversely affect in any
material way awards already granted without written consent of the recipient of such awards. Unless terminated
earlier, our 2008 share incentive plan shall continue in effect for a term of ten years from the date of adoption.

C. Board Practices

Board of Directors

Our board of directors has five directors. A director is not required to hold any shares in the company by way of
qualification. A director may vote with respect to any contract, proposed contract or arrangement in which he is
materially interested. A director may exercise all the powers of the company to borrow money, mortgage its
undertakings, property and uncalled capital, and issue debentures or other securities whenever money is borrowed
or as security for any obligation of the company or of any third party. The remuneration to be paid to the directors is
determined by the board of directors. There is no age limit requirement for directors.

Committees of the Board of Directors

We have three committees under the board of directors: an audit committee, a compensation committee and a
corporate governance and nominating committee. We have adopted a charter for each of the three committees.

Audit Committee

Our audit committee consists of Messrs. William Decker, James Ding and Greg Penner, all of whom satisfy the
“independence” requirements of Rule 5605(a)(2) of the NASDAQ Stock Market Rules and Rule 10A-3 under the
Securities Exchange Act of 1934, as amended. Our board of directors has determined that Mr. Decker is an audit
committee financial expert as defined in the instructions to Item 16A of the Form 20-F. The audit committee
oversees our accounting and financial reporting processes and the audits of the financial statements of our company.
The audit committee is responsible for, among other things:

(cid:129) appointing,

retaining and overseeing the work of

the independent auditors,

including resolving

disagreements between the management and the independent auditors relating to financial reporting;

(cid:129) pre-approving all auditing and non-auditing services permitted to be performed by the independent auditors;

(cid:129) reviewing annually the independence and quality control procedures of the independent auditors;

(cid:129) reviewing and approving all proposed related party transactions;

86

(cid:129) discussing the annual audited financial statements with the management;

(cid:129) meeting separately with the independent auditors to discuss critical accounting policies, management letters,
recommendations on internal controls, the auditor’s engagement letter and independence letter and other
material written communications between the independent auditors and the management; and

(cid:129) attending to such other matters that are specifically delegated to our audit committee by our board of

directors from time to time.

In 2010, our audit committee held meetings or passed resolutions by unanimous written consent six times.

Compensation Committee

Our compensation committee consists of Messrs. James Ding and Greg Penner, both of whom satisfy the
“independence” requirements of Rule 5605(a)(2) of the NASDAQ Stock Market Rules. The compensation
committee assists the board in reviewing and approving our compensation structure, including all forms of
compensation relating to our directors and executive officers. Our chief executive officer may not be present at any
committee meeting while his compensation is deliberated. The compensation committee is responsible for, among
other things:

(cid:129) reviewing and approving executive compensation;

(cid:129) reviewing periodically and approving any long-term incentive compensation or equity plans, programs or

similar arrangements, annual bonuses, employee pension and welfare benefit plans;

(cid:129) determining our policy with respect to change of control or “parachute” payments; and

(cid:129) managing and reviewing director and executive officer indemnification and insurance matters.

In 2010, our compensation committee passed resolutions by unanimous written consent four times.

Corporate Governance and Nominating Committee

Our corporate governance and nominating committee consists of Messrs. James Ding and Greg Penner, both of
whom satisfy the “independence” requirements of Rule 5605(a)(2) of the NASDAQ Stock Market Rules. The
corporate governance and nominating committee assists the board of directors in selecting individuals qualified to
become our directors and in determining the composition of the board and its committees. The corporate
governance and nominating committee is responsible for, among other things:

(cid:129) recommending to the board nominees for election or re-election to the board or for appointments to fill any

vacancies;

(cid:129) reviewing annually the performance of each incumbent director in determining whether to recommend such

director for an additional term;

(cid:129) overseeing the board in the board’s annual review of its own performance and the performance of the

management; and

(cid:129) considering, preparing and recommending to the board such policies and procedures with respect to
corporate governance matters as may be required or required to be disclosed under the applicable laws or
otherwise considered to be material.

In 2010, our corporate governance and nominating committee passed resolutions by unanimous written

consent once.

Terms of Directors and Executive Officers

All directors hold office until their successors have been duly elected and qualified. None of our directors is
subject to a fixed term of office. In addition, the service agreements between us and the directors do not provide
benefits upon termination of their services. Director nomination is subject to the approval of our corporate
governance and nominating committee. Our shareholders may remove any director by ordinary resolution and may

87

in like manner appoint another person in his stead. A valid ordinary resolution requires a majority of the votes cast at
a shareholder meeting that is duly constituted and meets the quorum requirement. Officers are elected by and serve
at the discretion of the board of directors.

D. Employees

We had 6,387, 7,353 and 10,887 employees as of December 31, 2008, 2009 and 2010, respectively. As of
December 31, 2010, we had 549 employees in management and administration, 3,645 employees in research and
development, 795 employees in operation and service, and 5,898 employees in sales and marketing. As of
December 31, 2010, we had 6,837 employees in Beijing, 4,014 employees outside Beijing but within China, and
36 employees outside China. We also hire temporary employees and contractors from time to time. Our employees
are not covered by any collective bargaining agreement. We consider our relations with our employees to be
generally good. However, as our operations and employee base further expand, we cannot assure you that we will
always be able to maintain good relations with all of our employees. See “Item 3.D. Key Information — Risk
Factors — Risks Related to Our Business — We may not be able to manage our expanding operations effectively.”

E. Share Ownership

The following table sets forth information with respect to the beneficial ownership of our shares as of

December 31, 2010 by:

(12) Represents 2,621,936 Class A ordinary shares in the form of ADSs held by Baillie Gifford & Co (Scottish
partnership), as reported on Schedule 13G filed by Baillie Gifford & Co (Scottish partnership) on January 25,
2011. The percentage of beneficial ownership was calculated based on the total number of our ordinary shares
outstanding as of December 31, 2010. The address of Baillie Gifford & Co (Scottish partnership) is Calton

Our ordinary shares are divided into Class A ordinary shares and Class B ordinary shares. Holders of Class A
ordinary shares are entitled to one vote per share, while holders of Class B ordinary shares are entitled to 10 votes
per share. We issued Class A ordinary shares represented by our ADSs in our initial public offering in 2005. Holders
of our Class B ordinary shares may choose to convert their Class B ordinary shares into the same number of Class A
ordinary shares at any time. We are not aware of any arrangement that may, at a subsequent date, result in a change
of control of our company. See “Item 3.D. Key Information — Risk Factors — Risks Related to Our ADSs — Our
dual-class ordinary share structure with different voting rights could discourage others from pursuing any change of
control transactions that holders of our Class A ordinary shares and ADSs may view as beneficial.”

As of December 31, 2010, 34,849,672 of our ordinary shares were issued and outstanding. To our knowledge,
approximately 78.7% of our total outstanding ordinary shares were held by six record shareholders in the United
States, including approximately 77.5% held by The Bank of New York Mellon, the depositary of our ADS program.
The number of beneficial owners of our ADSs in the United States is likely to be much larger than the number of
record holders of our ordinary shares in the United States.

Item 8. Financial Information

A. Consolidated Statements and Other Financial Information

We have appended consolidated financial statements filed as part of this annual report.

Legal Proceedings

From time to time, we have been involved in litigation or other disputes regarding, among other things,
copyright and trademark infringement, defamation, unfair competition and labor disputes. Our search results
provide links to materials, and our Baidu Post Bar, Baidu Knows, Baidu Space and other Baidu communities may
contain materials, in which others may allege to own copyrights, trademarks or image rights or which others may
claim to be defamatory or objectionable. We have received notice letters from third parties asserting copyright
infringement, unfair competition, defamation, breach of contract and labor-related claims against us.

As of December 31, 2010, we were involved in 50 cases pending in various PRC courts, including the cases
summarized below. The aggregate amount of compensation sought under these cases is approximately
RMB132.9 million (US$20.1 million).

In March 2008, we received complaints filed by three record companies against us, alleging, among other
things, that we have aided illegal online copying of music by providing links to pirated music. In January 2010, the

90

First Intermediate People’s Court of Beijing, in separately issued rulings, dismissed the complaints filed by the three
record companies. Applying the Protection of the Right of Communication through Information Network, which
was promulgated by the State Council and became effective on July 1, 2006, the court held that the record
companies’ claims lacked factual and legal basis. The plaintiffs have filed appeals with the High People’s Court of
Beijing. In December 2009, the Haidian District People’s Court in Beijing issued a ruling against us in a lawsuit
filed by the Music Copyright Society of China. In the ruling, the court held that our display of certain song lyrics in
response to users’ search requests constituted infringement of the plaintiff’s rights of communication through
information network, and ordered us to pay for the plaintiff’s damages and litigation related expenses. We appealed
the court’s ruling with the First Intermediate People’s Court of Beijing. On July 19, 2010, the First Intermediate
People’s Court of Beijing ruled in the plaintiff’s favor, and upheld the award for the plaintiff. See “Item 3.D. Key
Information — Risk Factors — Risks Related to Our Business — We may face intellectual property infringement
claims and other related claims that could be time-consuming and costly to defend and may result in our inability to
continue providing certain of our existing services.”

In January 2009, we received a complaint filed by a medical company alleging that we had violated the new
PRC Anti-Monopoly Law by abusing our dominant market position to screen out the website of the medical
company. In December 2009, the First Intermediate People’s Court of Beijing issued a ruling dismissing all the
claims made by the plaintiff. In the ruling, the court held, among other things, that the plaintiff’s allegation that we
have abused dominant market position as defined in the Anti-Monopoly Law lacks factual and legal support. The
plaintiff filed an appeal with the High People’s Court of Beijing. On July 9, 2010, the High People’s Court of Beijing
upheld the First Intermediate People’s Court’s ruling in favor of us. The plaintiff has not filed any further appeals.
Because the Anti-Monopoly Law is still new, and there have been very few court rulings and no judicial or
administrative interpretations on certain key concepts used in the law, there is no assurance that a court would reach
the same conclusion in a similar case against us in the future.

In June 2009, a plaintiff filed a lawsuit against us in the U.S. District Court for the Southern District of New
York, alleging that we had infringed its copyrights to certain music works. In December 2009, the court granted our
motion to dismiss the complaint on the grounds of insufficient service of process and lack of personal jurisdiction.
The plaintiff did not appeal the court’s ruling.

Although we cannot predict with certainty the results of pending litigation and claims, we believe that the final
outcome of pending litigation and claims will not have a material adverse effect on our business and results of
operations. Regardless of the outcome, however, any litigation can result in substantial costs and diversion of
management resources and attention.

Dividend Policy

We have never declared or paid any dividends, nor do we have any present plan to pay any cash dividends on
our ordinary shares in the foreseeable future. We currently intend to retain most, if not all, of our available funds and
any future earnings to operate and expand our business.

Our board of directors has complete discretion whether to distribute dividends. Even if our board of directors
decides to pay dividends, the form, frequency and amount of our dividends will depend upon our future operations
and earnings, capital requirements and surplus, financial condition, contractual restrictions and other factors that
our board of directors may deem relevant. If we pay any dividends, we will pay our ADS holders to the same extent
as holders of our ordinary shares, subject to the terms of the deposit agreement, including the fees and expenses
payable thereunder. Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars.

B. Significant Changes

Except as disclosed elsewhere in this annual report, we have not experienced any significant changes since the

date of our audited consolidated financial statements included in this annual report.

Item 9. The Offer and Listing

A. Offering and Listing Details.

Our ADSs have been listed on The NASDAQ Global Market since August 5, 2005. Our ADSs currently trade
on The NASDAQ Global Select Market under the symbol “BIDU.” Prior to May 12, 2010, one ADS represented one
Class A ordinary share. On May 12, 2010, we effected a change of the ADS to Class A ordinary share ratio from 1
ADS representing 1 Class A ordinary share to 10 ADSs representing 1 Class A ordinary share. The ratio change has
the same effect as a 10-for-1 ADS split.

The following table provides the high and low trading prices for our ADSs on the NASDAQ for (1) the years
2006, 2007, 2008, 2009 and 2010, (2) each of the four quarters of 2009 and 2010 and (3) each of the past six months.
For ease of comparison, the ADS prices before May 12, 2010 have been retroactively adjusted to reflect the ADS to
Class A ordinary share ratio change that took effect on May 12, 2010.

B. Memorandum and Articles of Association

The following are summaries of material provisions of our third amended and restated memorandum and
articles of association, as well as the Companies Law (2010 Revision) insofar as they relate to the material terms of
our ordinary shares.

Registered Office and Objects

The Registered Office of our company is at the offices of Maples Corporate Services Limited, PO Box 309,
Ugland House, Grand Cayman, KY1-1104, Cayman Islands or at such other place as our board of directors may
from time to time decide. The objects for which our company is established are unrestricted and we have full power
and authority to carry out any object not prohibited by the Companies Law (2010 Revision), as amended from time
to time, or any other law of the Cayman Islands.

Board of Directors

See “Item 6.C. Board Practices — Board of Directors.”

Ordinary Shares

General. Our ordinary shares are divided into Class A ordinary shares and Class B ordinary shares. Holders
of Class A ordinary shares and Class B ordinary shares have the same rights except for voting and conversion rights.
All of our outstanding ordinary shares are fully paid and non-assessable. Certificates representing the ordinary
shares are issued in registered form. Our shareholders who are nonresidents of the Cayman Islands may freely hold
and vote their shares.

Dividends. The holders of our ordinary shares are entitled to such dividends as may be declared by our board

of directors subject to the Companies Law.

Conversion. Each Class B ordinary share is convertible into one Class A ordinary share at any time by the
holder thereof. Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances.
Upon any transfer of Class B ordinary shares by a holder thereof to any person or entity which is not an affiliate of
such holder (as defined in our articles of incorporation), such Class B ordinary shares shall be automatically and
immediately converted into the equal number of Class A ordinary shares. In addition, if at any time our chairman
and chief executive officer, Robin Yanhong Li, and his affiliates collectively own less than 5% of the total number of
the issued and outstanding Class B ordinary shares, each issued and outstanding Class B ordinary share shall be
automatically and immediately converted into one share of Class A ordinary share, and we shall not issue any
Class B ordinary shares thereafter.

Voting Rights. All of our shareholders have the right to receive notice of shareholders’ meetings and to
attend, speak and vote at such meetings. In respect of matters requiring shareholders’ vote, each Class A ordinary
share is entitled to one vote, and each Class B ordinary share is entitled to 10 votes. A shareholder may participate at
a shareholders’ meeting in person, by proxy or by telephone conference or other communications equipment by
means of which all the shareholders participating in the meeting can communicate with each other. At any

93

shareholders’ meeting, a resolution put to the vote of the meeting shall be decided on a poll conducted by the
chairman of the meeting.

A quorum for a shareholders’ meeting consists of one or more shareholders holding at least one third of the
paid up voting share capital present in person or by proxy or, if a corporation or other non-natural person, by its duly
authorized representative. We shall, if required by the Companies Law, hold a general meeting of shareholders as
our annual general meeting and shall specify the meeting as such in the notices calling it. Our board of directors may
call extraordinary general meetings, and they must on shareholders’ requisition convene an extraordinary general
meeting. A shareholder requisition is a requisition of shareholders holding at the date of deposit of the requisition
not less than a majority of the voting power represented by the issued shares of our company as at that date carries
the right of voting at general meetings of our company. Advance notice of at least five days is required for the
convening of our annual general meeting and other shareholders’ meetings.

An ordinary resolution to be passed by the shareholders requires the affirmative vote of a simple majority of the
votes attaching to the ordinary shares cast in a general meeting, while a special resolution requires the affirmative
vote of no less than two-thirds of the votes cast attaching to the ordinary shares cast in a general meeting. A special
resolution is required for matters such as a change of name. Holders of the ordinary shares may effect certain
changes by ordinary resolution, including consolidating and dividing all or any of our share capital into shares of
larger amount than our existing share capital and canceling any shares.

Transfer of Shares. Subject to the restrictions of our memorandum and articles of association, as applicable,
any of our shareholders may transfer any or all of his or her ordinary shares by an instrument of transfer in the usual
or common form or any other form approved by our board of directors.

Our board of directors may, in their absolute discretion (except with respect to a transfer from a shareholder to
its affiliate(s)), decline to register any transfer of shares without assigning any reason thereof. If our board of
directors refuses to register a transfer they shall notify the transferee within two months of such refusal.
Notwithstanding the foregoing, if a transfer complies with the holder’s transfer obligations and restrictions set
forth under applicable law (including but not limited to U.S. securities law provisions related to insider trading) and
our articles of association, our board of directors shall promptly register such transfer. Further, any director is
authorized to confirm in writing addressed to the registered office to authorize a share transfer and to instruct that
the register of members be updated accordingly, provided that the transfer complies with the holder’s transfer
obligations and restrictions set forth under applicable law and our articles of association and such holder is not the
director who authorizes the transfer or an entity affiliated with such director. Any director is authorized to execute a
share certificate in respect of such shares for and on behalf of our company.

The registration of transfers may be suspended at such time and for such periods as our board of directors may
from time to time determine, provided, however, that the registration of transfers shall not be suspended for more
than 45 days in any year.

Liquidation. On a return of capital on winding up or otherwise (other than on conversion, redemption or
purchase of shares), assets available for distribution among the holders of ordinary shares may be distributed among
the holders of the ordinary shares as determined by the liquidator, subject to sanction of a special resolution of our
company. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be
distributed so that the losses are borne by our shareholders proportionately to the capital paid up, or which ought to
have been paid up, at the commencement of the winding up on the shares held by such shareholders respectively.

Calls on Shares and Forfeiture of Shares. Our board of directors may from time to time make calls upon
shareholders for any amounts unpaid on their shares in a notice served to such shareholders at least 14 days prior to
the specified time and place of payment. The shares that have been called upon and remain unpaid on the specified
time are subject to forfeiture.

Redemption of Shares. Subject to the provisions of the Companies Law and our articles of association, we
may issue shares on terms that are subject to redemption, at our option or at the option of the holders, on such terms
and in such manner as our board of directors may determine.

94

Repurchase of Shares. Subject to the provisions of the Companies Law and our articles of association, our
board of directors may authorize repurchase of our shares in accordance with the manner of purchase specified in
our articles of association without seeking shareholder approval.

Variations of Rights of Shares. All or any of the special rights attached to any class of shares may, subject to
the provisions of the Companies Law, be varied either with the written consent of the holders of a majority of the
issued shares of that class or with the sanction of a special resolution passed at a general meeting of the holders of
the shares of that class.

Inspection of Books and Records. No holders of our ordinary shares who is not a director shall have any
right of inspecting any of our accounts, books or documents except as conferred by the Companies Law or
authorized by the directors or by us in general meeting. However, we will make this annual report, which contains
our audited financial statements, available to shareholders and ADS holders. See “Item 10.H. Additional
Information — Documents on Display.”

Preferred Shares

Our board of directors has the authority, without shareholder approval,

to issue up to a total of
10,000,000 shares of preferred shares in one or more series. Our board of directors may establish the number
of shares to be included in each such series and may set the designations, preferences, powers and other rights of the
shares of a series of preferred shares. While the issuance of preferred shares provides us with flexibility in
connection with possible acquisitions or other corporate purposes, it could, among other things, have the effect of
delaying, deferring or preventing a change of control transaction and could adversely affect the market price of our
ADSs. We have no current plan to issue any preferred shares.

C. Material Contracts

We have not entered into any material contracts other than in the ordinary course of business and other than

those described in “Item 4. Information on the Company” or elsewhere in this annual report on Form 20-F.

D. Exchange Controls

See “Item 4.B. Information on the Company — Business Overview — Regulation — Regulations on Foreign

Exchange.”

E. Taxation

The following summary of the material Cayman Islands, People’s Republic of China and United States federal
income tax consequences of an investment in our ADSs or ordinary shares is based upon laws and relevant
interpretations thereof in effect as of the date of this annual report, all of which are subject to change. This summary
does not deal with all possible tax consequences relating to an investment in our ADSs or ordinary shares, such as
the tax consequences under state, local and other tax laws.

Cayman Islands Taxation

According to Maples and Calder, our Cayman Islands counsel, the Cayman Islands currently levies no taxes on
individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of
inheritance tax or estate duty. There are no other taxes likely to be material to us levied by the Government of the
Cayman Islands except for stamp duties which may be applicable on instruments executed in, or brought within, the
jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties that are applicable to
any payments made to or by our Company. There are no exchange control regulations or currency restrictions in the
Cayman Islands.

People’s Republic of China Taxation

If we are considered a PRC resident enterprise under the EIT Law, our shareholders and ADS holders who are
deemed non-resident enterprises may be subject to the 10% EIT on the dividends payable by us or any gains realized

95

from the transfer of our shares or ADSs, if such income is deemed derived from China, provided that (i) such foreign
enterprise investor has no establishment or premises in China, or (ii) it has establishment or premises in China but its
income derived from China has no real connection with such establishment or premises. Furthermore, if we are
considered a PRC resident enterprise and relevant PRC tax authorities consider the dividends we pay with respect to
our shares or ADSs and the gains realized from the transfer of our shares or ADSs to be income derived from sources
within the PRC, such dividends and gains earned by non-resident individuals may be subject to the 20% PRC
individual income tax.

If we are required under the PRC tax laws to withhold PRC income tax on our dividends payable to our non-
PRC shareholders and ADS holders, or if any gains realized from the transfer of our shares or ADSs by our non-PRC
shareholders and ADS holders are subject to the EIT or the individual income tax, your investment in our shares or
ADSs could be materially and adversely affected.

United States Federal Income Taxation

The following discussion describes certain material United States federal income tax considerations under
present law of the purchase, ownership and disposition of the ADSs or ordinary shares. This summary applies only
to investors that are U.S. Holders (as defined below) and that hold the ADSs or ordinary shares as capital assets and
that have the U.S. dollar as their functional currency. This discussion is based on the tax laws of the United States as
in effect on the date of this Form 20-F and on United States Treasury regulations in effect or, in some cases,
proposed, as of the date of this Form 20-F, as well as judicial and administrative interpretations thereof available on
or before such date. All of the foregoing authorities are subject to change, which change could apply retroactively
and could affect the tax considerations described below.

The following discussion does not deal with the tax consequences to any particular investor or to persons in

special tax situations such as:

(cid:129) banks;

(cid:129) financial institutions;

(cid:129) insurance companies;

(cid:129) broker dealers;

(cid:129) traders that elect to mark to market;

(cid:129) tax-exempt entities;

(cid:129) persons liable for alternative minimum tax;

(cid:129) regulated investment companies;

(cid:129) certain expatriates or former long-term residents of the United States;

(cid:129) governments or agencies or instrumentalities thereof;

(cid:129) persons holding an ADS or ordinary share as part of a straddle, hedging, conversion or integrated

transaction;

(cid:129) persons that actually or constructively own 10% or more of our voting shares;

(cid:129) persons holding ADSs or ordinary shares through partnerships or other pass-through entities; or

(cid:129) persons who acquired ADSs or ordinary shares pursuant to the exercise of any employee share option or

otherwise as consideration.

U.S. Holders are urged to consult their tax advisors about the application of the United States federal tax
rules to their particular circumstances as well as the state and local and foreign tax consequences to them of
the purchase, ownership and disposition of ADSs or ordinary shares.

96

The discussion below of the United States federal income tax consequences will apply if you are a
“U.S. Holder.” You are a “U.S. Holder” if you are the beneficial owner of ADSs or ordinary shares and you
are, for United States federal income tax purposes,

(cid:129) a citizen or individual resident of the United States;

(cid:129) a corporation (or other entity subject to tax as a corporation for United States federal income tax purposes)
that is created or organized in or under the laws of the United States, any State or the District of Columbia;

(cid:129) an estate whose income is subject to United States federal income taxation regardless of its source; or

(cid:129) a trust that (1) is subject to the supervision of a court within the United States and the control of one or more
United States persons or (2) has a valid election in effect under applicable United States Treasury regulations
to be treated as a United States person.

This discussion does not consider the tax treatment of partnerships or other pass-through entities that hold the
ADSs or ordinary shares, or of persons who hold the ADSs or ordinary shares through such entities. If a partnership
(or other entity classified as a partnership for U.S. federal income tax purposes) is the beneficial owner of the ADSs
or ordinary shares, the U.S. federal income tax treatment of a partner in the partnership will generally depend on the
status of the partner and the activities of the partnership.

The discussion below assumes that the representations contained in the deposit agreement are true and that the
obligations in the deposit agreement and any related agreement will be complied with in accordance with their
terms. If you hold ADSs, you will be treated as the holder of the underlying ordinary shares represented by those
ADSs for United States federal income tax purposes.

This discussion does not address any aspect of U.S. federal non-income tax laws, such as gift or estate tax laws,
or state, local or non-U.S. tax laws. We have not sought, and will not seek, a ruling from the Internal Revenue
Service, or the IRS, or an opinion as to any U.S. federal income tax consequence described herein. The IRS may
disagree with the discussion herein, and its determination may be upheld by a court.

Taxation of Dividends and Other Distributions on the ADSs or Ordinary Shares

Subject to the passive foreign investment company rules discussed below, the gross amount of all our
distributions to you with respect to the ADSs or ordinary shares will be included in your gross income as dividend
income on the date of receipt by the depositary, in the case of ADSs, or by you, in the case of ordinary shares, but
only to the extent that the distribution is paid out of our current or accumulated earnings and profits (computed
under United States federal income tax principles). The dividends will not be eligible for the dividends-received
deduction allowed to corporations in respect of dividends received from U.S. corporations.

With respect to non-corporate U.S. Holders (including individual U.S. Holders) for taxable years beginning
before January 1, 2013, dividends may be taxed at the lower applicable capital gains rate (“qualified dividend
income”) provided that (1) the ADSs or ordinary shares are readily tradable on an established securities market in
the United States or we are eligible for the benefit of the income tax treaty between the United States and the PRC,
(2) we are not a passive foreign investment company (as discussed below) for either our taxable year in which the
dividend was paid or the preceding taxable year, (3) certain holding period requirements are met, and (4) such non-
corporate U.S. Holders are not under an obligation to make related payments with respect to positions in
substantially similar or related property. For this purpose, ADSs listed on the Nasdaq Global Market will
generally be considered to be readily tradable on an established securities market in the United States. You
should consult your tax advisor regarding the availability of the lower rate for dividends paid with respect to our
ADSs or ordinary shares.

Dividends will constitute foreign source income for foreign tax credit limitation purposes. If PRC withholding
taxes apply to dividends paid to you with respect to the ADSs or ordinary shares, you may be able to obtain a
reduced rate of PRC withholding taxes under the income tax treaty between the United States and the PRC if certain
requirements are met. In addition, subject to certain conditions and limitations, PRC withholding taxes on dividends
may be treated as foreign taxes eligible for credit against your U.S. federal income tax liability. U.S. Holders should
consult their own tax advisors regarding the creditability of any PRC tax. The limitation on foreign taxes eligible for

97

credit is calculated separately with respect to specific classes of income. For this purpose, dividends distributed by
us with respect to ADSs or ordinary shares will generally constitute “passive category income” but could, in the case
of certain U.S. Holders, constitute “general category income.”

To the extent that the amount of the distribution exceeds our current and accumulated earnings and profits, it
will be treated first as a tax-free return of your tax basis in your ADSs or ordinary shares, and to the extent the
amount of the distribution exceeds your tax basis, the excess will be taxed as capital gain. We do not intend to
calculate our earnings and profits for United States federal income tax purposes. Therefore, a U.S. Holder should
expect that a distribution will be reported as a dividend.

Taxation of Disposition of Shares

Subject to the passive foreign investment company rules discussed below, you will recognize taxable gain or
loss on any sale, exchange or other taxable disposition of an ADS or ordinary share equal to the difference between
the amount realized (in U.S. dollars) for the ADS or ordinary share and your tax basis (in U.S. dollars) in the ADS or
ordinary share. The gain or loss will generally be capital gain or loss. If you are a non-corporate U.S. Holder,
including an individual U.S. Holder, who has held the ADS or ordinary share for more than one year, you will
generally be eligible for reduced tax rates. The deductibility of capital losses is subject to limitations. Any such gain
or loss that you recognize will generally be treated as United States source income or loss (in the case of losses,
subject to certain limitations). However, in the event we are deemed to be a Chinese “resident enterprise” under
PRC tax law, we may be eligible for the benefits of the income tax treaty between the United States and the PRC. In
such event, if PRC tax were to be imposed on any gain from the disposition of the ADSs or ordinary shares, a
U.S. Holder that is eligible for the benefits of the income tax treaty between the United States and the PRC may elect
to treat such gain as PRC source income. U.S. Holders should consult their own tax advisors regarding the
creditability of any PRC tax.

Passive Foreign Investment Company

Based on the market value of our ADSs and ordinary shares, the composition of our assets and income and our
operations, we believe that for our taxable year ended December 31, 2010, we were not a passive foreign investment
company (“PFIC”) for United States federal income tax purposes. However, our PFIC status for the current taxable
year ending December 31, 2011 will not be determinable until its close, and, accordingly, there is no guarantee that
we will not be a PFIC for the current taxable year (or any future taxable year). A non-U.S. corporation is considered
a PFIC for any taxable year if either:

(cid:129) at least 75% of its gross income is passive income (the “income test”), or

(cid:129) at least 50% of the value of its assets (based on an average of the quarterly values of the assets during a
taxable year) is attributable to assets that produce or are held for the production of passive income (the “asset
test”).

We will be treated as owning our proportionate share of the assets and earning our proportionate share of the
income of any other corporation in which we own, directly or indirectly, more than 25% (by value) of the shares.

We must make a separate determination each year as to whether we are a PFIC. As a result, our PFIC status
may change. In particular, because the total value of our assets for purposes of the asset test will generally be
calculated using the market price of our ADSs and ordinary shares, our PFIC status will depend in large part on the
market price of our ADSs and ordinary shares which may fluctuate considerably. Accordingly, fluctuations in the
market price of the ADSs and ordinary shares may result in our being a PFIC for any year. If we are a PFIC for any
year during which you hold ADS or ordinary shares, we will generally continue to be treated as a PFIC for all
succeeding years during which you hold ADS or ordinary shares. However, if we cease to be a PFIC, provided that
you have not made a mark-to-market election, as described below, you may avoid some of the adverse effects of the
PFIC regime by making a deemed sale election with respect to the ADSs or ordinary shares, as applicable.

If we are a PFIC for any taxable year during which you hold ADSs or ordinary shares, you will be subject to
special tax rules with respect to any “excess distribution” that you receive and any gain you realize from a sale or
other disposition (including a pledge) of the ADSs or ordinary shares, unless you make a “mark-to-market” election

98

as discussed below. Distributions you receive in a taxable year that are greater than 125% of the average annual
distributions you received during the shorter of the three preceding taxable years or your holding period for the
ADSs or ordinary shares will be treated as an excess distribution. Under these special tax rules:

(cid:129) the excess distribution or gain will be allocated ratably over your holding period for the ADSs or ordinary

shares,

(cid:129) the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which

we became a PFIC, will be treated as ordinary income, and

(cid:129) the amount allocated to each other taxable year will be subject to the highest tax rate in effect for that taxable
year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting
tax attributable to each such taxable year.

The tax liability for amounts allocated to years prior to the year of disposition or “excess distribution” cannot
be offset by any net operating losses for such years, and gains (but not losses) realized on the sale of the ADSs or
ordinary shares cannot be treated as capital, even if you hold the ADSs or ordinary shares as capital assets.

Alternatively, a U.S. Holder of “marketable stock” (as defined below) in a PFIC may make a mark-to-market
election for such stock of a PFIC to elect out of the tax treatment discussed in the two preceding paragraphs. If you
make a valid mark-to-market election for the ADSs or ordinary shares, you will include in income each year an
amount equal to the excess, if any, of the fair market value of the ADSs or ordinary shares as of the close of your
taxable year over your adjusted basis in such ADSs or ordinary shares. You are allowed a deduction for the excess, if
any, of the adjusted basis of the ADSs or ordinary shares over their fair market value as of the close of the taxable
year. Such deductions, however, are allowable only to the extent of any net mark-to-market gains on the ADSs or
ordinary shares included in your income for prior taxable years. Amounts included in your income under a
mark-to-market election, as well as gain on the actual sale or other disposition of the ADSs or ordinary shares, are
treated as ordinary income. Ordinary loss treatment also applies to the deductible portion of any mark-to-market
loss on the ADSs or ordinary shares, as well as to any loss realized on the actual sale or disposition of the ADSs or
ordinary shares, to the extent that the amount of such loss does not exceed the net mark-to-market gains previously
included for such ADSs or ordinary shares. Your basis in the ADSs or ordinary shares will be adjusted to reflect any
such income or loss amounts. If you make such a mark-to-market election, tax rules that apply to distributions by
corporations which are not PFICs would apply to distributions by us (except that the lower applicable capital gains
rate would not apply).

The mark-to-market election is available only for “marketable stock” which is stock that is traded in other than
de minimis quantities on at least 15 days during each calendar quarter (“regularly traded”) on a qualified exchange
or other market, as defined in applicable Treasury regulations. We expect that the ADSs will continue to be listed on
the Nasdaq National Market, which is a qualified exchange for these purposes, and, consequently, assuming that the
ADSs are regularly traded, if you are a holder of ADSs, it is expected that the mark-to-market election would be
available to you were we to become a PFIC.

Alternatively, a U.S. Holder may avoid the PFIC tax consequences described above in respect to its ADSs and
ordinary shares by making a timely “qualified electing fund,” or QEF, election. In order to comply with the
requirements of a QEF election, a U.S. Holder must receive certain information from us. We, however, do not intend
to provide such information.

If you hold ADSs or ordinary shares in any year in which we are a PFIC, you will be required to file Internal
Revenue Service Form 8621 regarding distributions received on the ADSs or ordinary shares and any gain realized
on the disposition of the ADSs or ordinary shares.

You are urged to consult your tax advisor regarding the application of the PFIC rules to your investment in

ADSs or ordinary shares.

Information Reporting and Backup Withholding

Dividend payments with respect to ADSs or ordinary shares and proceeds from the sale, exchange or
redemption of ADSs or ordinary shares may be subject to information reporting to the IRS and possible U.S. backup

99

withholding at a current rate of 28%. Backup withholding will not apply, however, to a U.S. Holder that furnishes a
correct taxpayer identification number and makes any other required certification or that is otherwise exempt from
backup withholding. U.S. Holders that are required to establish their exempt status generally must provide such
certification on Internal Revenue Service Form W-9. U.S. Holders should consult their tax advisors regarding the
application of the U.S. information reporting and backup withholding rules.

Pursuant to the Hiring Incentives to Restore Employment Act enacted on March 18, 2010, in tax years
beginning after the date of enactment, an individual U.S. Holder and certain entities may be required to submit to the
IRS certain information with respect to his or her beneficial ownership of the ADSs or ordinary shares, if such ADSs
or ordinary shares are not held on his or her behalf by a U.S. financial institution. This new law also imposes
penalties if an individual U.S. Holder is required to submit such information to the IRS and fails to do so.

Backup withholding is not an additional tax. Amounts withheld as backup withholding can be credited against
your U.S. federal income tax liability, and you may obtain a refund of any excess amounts withheld under the
backup withholding rules by timely filing the appropriate claim for refund with the Internal Revenue Service and
furnishing any required information in a timely manner.

We previously filed with the SEC our registration statement on Form F-1, as amended and prospectus under the

Securities Act of 1933, with respect to our ordinary shares.

We are subject to the periodic reporting and other informational requirements of the Securities Exchange Act
of 1934, as amended, or the Exchange Act. Under the Exchange Act, we are required to file reports and other
information with the SEC. Specifically, we are required to file annually a Form 20-F: (1) within six months after the
end of each fiscal year, which is December 31, for fiscal years ending before December 15, 2011; and (2) within four
months after the end of each fiscal year for fiscal years ending on or after December 15, 2011. Copies of reports and
other information, when so filed, may be inspected without charge and may be obtained at prescribed rates at the
public reference facilities maintained by the Securities and Exchange Commission at 100 F Street, N.E.,
Room 1580, Washington, D.C. 20549. The public may obtain information regarding the Washington, D.C.
Public Reference Room by calling the Commission at 1-800-SEC-0330. The SEC also maintains a website at
www.sec.gov that contains reports, proxy and information statements, and other information regarding registrants
that make electronic filings with the SEC using its EDGAR system. As a foreign private issuer, we are exempt from
the rules under the Exchange Act prescribing the furnishing and content of quarterly reports and proxy statements,
and officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery
provisions contained in Section 16 of the Exchange Act.

We will furnish The Bank of New York Mellon, the depositary of our ADSs, with our annual reports, which
will include a review of operations and annual audited consolidated financial statements prepared in conformity
with U.S. GAAP, and all notices of shareholders’ meetings and other reports and communications that are made
generally available to our shareholders. The depositary will make such notices, reports and communications
available to holders of ADSs and, upon our request, will mail to all record holders of ADSs the information
contained in any notice of a shareholders’ meeting received by the depositary from us.

In accordance with NASDAQ Stock Market Rule 5250(d), we will post this annual report on Form 20-F on our
website at http://ir.baidu.com. In addition, we will provide hardcopies of our annual report free of charge to
shareholders and ADS holders upon request.

Item 11. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

Our exposure to interest rate risk primarily relates to excess cash invested in short-term fixed income
instruments with original maturities of less than a year. Investments in both fixed rate and floating rate interest
earning instruments carry a degree of interest rate risk. Fixed rate securities may have their fair market value
adversely impacted due to a rise in interest rates, while floating rate securities may produce less income than
expected if interest rates fall. Due in part to these factors, our future investment income may fall short of
expectations due to changes in interest rates, or we may suffer losses in principal if we have to sell securities which
have declined in market value due to changes in interest rates. We have not been, and do not expect to be, exposed to
material interest rate risks, and therefore have not used any derivative financial instruments to manage our interest
risk exposure.

We had RMB376.5 million (US$57.0 million) short-term investments as of December 31, 2010, with a
weighted average duration of approximately 0.1 year. A hypothetical one percentage point (100 basis-point)
increase in interest rates would have resulted in a decrease of approximately RMB0.4 million (US$0.1 million) in
the fair value of our fixed-income investments at December 31, 2010.

Foreign Exchange Risk

Most of our revenues and costs are denominated in RMB, while a significant portion of our cash and cash
equivalents and short-term financial assets are denominated in U.S. dollars and held by the Cayman holding
company. Our exposure to foreign exchange risk primarily relates to those financial assets denominated in
U.S. dollars. Any significant revaluation of RMB against the U.S. dollar may materially affect our revenues,
earnings and financial position, and the value of, and any dividends payable on, our ADS in U.S. dollars. See
“Item 3.D. Key Information — Risk Factors — Risks Related to Doing Business in China — Fluctuation in the
value of the RMB may have a material adverse effect on your investment.” In addition, we commenced operation in
Japan in late 2007. To the extent we need to make capital injections into our Japan operation by converting
U.S. dollars into Japanese Yen, we will be exposed to the fluctuations in the exchange rate between the U.S. dollar
and the Japanese Yen. We have not hedged exposures denominated in foreign currencies using any derivative
financial instruments.

The RMB appreciated by 3.31% against the U.S. dollar in 2010. A hypothetical 10% decrease in the exchange
rate of the U.S. dollar against the RMB would have resulted in a decrease of RMB32.1 million (US$4.9 million) in
the value of our U.S. dollar-denominated financial assets at December 31, 2010.

D. American Depositary Shares

Fees and Charges Our ADS holders May Have to Pay

The Bank of New York Mellon, the depositary of our ADS program, collects its fees for delivery and surrender
of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from
intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those
fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary
may collect its annual fee for depositary services by deductions from cash distributions or by directly billing
investors or by charging the book-entry system accounts of participants acting for them. The depositary may
generally refuse to provide fee-attracting services until its fees for those services are paid.

Persons depositing or
withdrawing shares must pay:
US$5.00 (or less) per 1,000 ADSs (or portion of
1,000 ADSs)

US$0.02 (or less) per ADS
A fee equivalent to the fee that would be payable if
securities distributed had been shares and the shares
had been deposited for issuance of ADSs
US$0.02 (or less) per ADS per calendar year (if the
depositary has not collected any cash distribution fee
during that year)
Expenses of the depositary

Registration or transfer fees

For:
(cid:129) Issuance of ADSs, including issuances resulting

Fees and Other Payments Made by the Depositary to Us

The depositary has agreed to reimburse us annually for our expenses incurred in connection with investor
relationship programs and any other program related to our ADS facility and the travel expense of our key personnel
in connection with such programs. The depositary has also agreed to provide additional payments to us based on the
applicable performance indicators relating to our ADS facility. There are limits on the amount of expenses for
which the depositary will reimburse us, but the amount of reimbursement available to us is not necessarily tied to the
amount of fees the depositary collects from investors. For the year ended December 31, 2010, we have received
US$3.5 million (subject to applicable withholding tax) reimbursement from the depositary for our expenses
incurred in connection with investor relationship programs related to the ADS facility and the travel expense of our
key personnel in connection with such programs.

Item 15. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, has
performed an evaluation of the effectiveness of our disclosure controls and procedures (as defined in
Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this report, as required by
Rule 13a-15(b) under the Exchange Act.

Based upon that evaluation, our management has concluded that, as of December 31, 2010, our disclosure
controls and procedures were effective in ensuring that the information required to be disclosed by us in the reports
that we file and furnish under the Exchange Act was recorded, processed, summarized and reported, within the time
periods specified in the SEC’s rules and forms, and that the information required to be disclosed by us in the reports
that we file or submit under the Exchange Act is accumulated and communicated to our management, including our
chief executive officer and chief financial officer, to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial
reporting, as defined in Rule 13a-15(f) under the Exchange Act. Our management evaluated the effectiveness of our
internal control over financial reporting, as required by Rule 13a-15(c) of the Exchange Act, based on criteria
established in the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission. Based on this evaluation, our management has concluded that our
internal control over financial reporting was effective as of December 31, 2010.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. In addition, projections of any evaluation of effectiveness of our internal control over financial
reporting to future periods are subject to the risk that controls may become inadequate because of changes in
conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Our independent registered public accounting firm, Ernst & Young Hua Ming, has audited the effectiveness of
our internal control over financial reporting as of December 31, 2010, as stated in its report, which appears on
page F-2 of this annual report on Form 20-F.

Changes in Internal Control over Financial Reporting

There were no changes in our internal controls over financial reporting that occurred during the period covered
by this annual report on Form 20-F that have materially affected, or are reasonably likely to materially affect, our
internal control over financial reporting.

Item 16A. Audit Committee Financial Expert

Our board of directors has determined that Mr. William Decker, an independent director (under the standards
set forth in NASDAQ Stock Market Rule 5605(a)(2) and Rule 10A-3 under the Exchange Act) and member of our
audit committee, is an audit committee financial expert.

Item 16B. Code of Ethics

Our board of directors adopted a code of business conduct and ethics that applies to our directors, officers,
employees and advisors in July 2005. We have posted a copy of our code of business conduct and ethics on our
website at http://ir.baidu.com.

(1) “Audit fees” means the aggregate fees billed in each of the fiscal years listed for professional services rendered
by our principal auditors for the audit of our annual financial statements. In 2009 and 2010, the audit refers to
integrated audit, including financial audit and audit pursuant to Section 404 of the Sarbanes-Oxley Act of 2002.

(2) “Tax fees” means the aggregate fees billed in each of the fiscal years listed for professional services rendered by
our principal auditors for tax compliance, tax advice, and tax planning. In 2009 and 2010, the tax fees refer to
fees paid to our principal auditors to review the compliance of our tax documentation.

All audit and non-audit services provided by our independent auditors must be pre-approved by our audit
committee. Our audit committee has adopted a combination of two approaches in pre-approving proposed services:
general pre-approval and specific pre-approval. With general approval, proposed services are pre-approved without
consideration of specific case-by-case services; with specific approval, proposed services require the specific pre-
approval of the audit committee. Unless a type of service has received general pre-approval, it will require specific
pre-approval by our audit committee. Any proposed services exceeding pre-approved cost levels or budgeted
amounts will also require specific pre-approval by our audit committee.

All requests or applications for services to be provided by our independent auditors that do not require specific
approval by our audit committee will be submitted to our chief financial officer and must include a detailed
description of the services to be rendered. The chief financial officer will determine whether such services are
included within the list of services that have received the general pre-approval of the audit committee. The audit
committee will be informed on a timely basis of any such services. Requests or applications to provide services that
require specific approval by our audit committee will be submitted to the audit committee by both our independent
auditors and our chief financial officer and must include a joint statement as to whether, in their view, the request or
application is consistent with the SEC’s rules on auditor independence.

Item 16D. Exemptions from the Listing Standards for Audit Committees

Not applicable.

Item 16E. Purchases of Equity Securities by the Issuer and Affiliated Purchasers

None.

Item 16F. Change in Registrant’s Certifying Accountant

Not applicable.

Item 16G. Corporate Governance

NASDAQ Stock Market Rule 5620 requires each issuer to hold an annual meeting of shareholders no later than
one year after the end of the issuer’s fiscal year-end. However, NASDAQ Stock Market Rule 5615(a)(3) permits
foreign private issuers like us to follow “home country practice” in certain corporate governance matters. Maples
and Calder, our Cayman Islands counsel, has provided a letter to the NASDAQ Stock Market certifying that under
Cayman Islands law, we are not required to hold annual shareholder meetings every year. We follow home country
practice with respect to annual meetings and did not hold an annual meeting of shareholders in 2010. We may,
however, hold annual shareholder meetings in the future if there are significant issues that require shareholders’
approvals.

Other than the annual meeting practice described above, there are no significant differences between our
corporate governance practices and those followed by U.S. domestic companies under NASDAQ Stock Market
Rules.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Baidu, Inc.

We have audited the accompanying consolidated balance sheets of Baidu, Inc. (the “Company”) as of
December 31, 2010 and 2009, and the related consolidated statements of income, shareholders’ equity, and cash
flows for each of the three years in the period ended December 31, 2010. These financial statements are the
responsibility of the Company’s management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the
consolidated financial position of Baidu, Inc. as of December 31, 2010 and 2009, and the consolidated results
of its operations and its cash flows for each of the three years in the period ended December 31, 2010, in conformity
with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), Baidu, Inc.’s internal control over financial reporting as of December 31, 2010, based on criteria
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the
Treadway Commission and our report dated March 29, 2011 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Baidu, Inc.

We have audited Baidu, Inc.’s internal control over financial reporting as of December 31, 2010, based on
criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (the COSO criteria). Baidu, Inc.’s management is responsible for
maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal
control over financial reporting included in the accompanying Management’s Report on Internal Control over
Financial 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 require that we plan and perform the audit to obtain reasonable assurance about
whether effective internal control over financial reporting was maintained in all material respects. Our audit
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk, and performing such other procedures 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 financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles. A company’s internal 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 are recorded as necessary to permit preparation of financial statements in accordance
with generally accepted accounting principles, and that receipts and expenditures of the company are being made
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s
assets that could have a 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 any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

In our opinion, Baidu, Inc. maintained, in all material respects, effective internal control over financial

reporting as of December 31, 2010, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the accompanying consolidated balance sheets of Baidu, Inc. as of December 31, 2010 and 2009,
and the related consolidated statements of income, shareholders’ equity, and cash flows for each of the three years in
the period ended December 31, 2010 of Baidu, Inc., and our report dated March 29, 2011, expressed an unqualified
opinion thereon.

F-8

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

scalable web application software and provides related services, as well as provides human resource related services
including employment agency services. The Group’s principal geographic market is in the PRC and Japan. The
Company does not conduct any substantive operations of its own but conducts its primary business operations
through its wholly-owned subsidiaries and VIEs in the PRC.

PRC laws and regulations prohibit or restrict foreign ownership of Internet content and advertising businesses.
To comply with these foreign ownership restrictions, the Group operates its websites and primarily provides online
advertising services in the PRC through VIEs, the PRC legal entities that were established by the individuals
authorized by the Group. The paid-in capital of the VIEs was funded by the Group through loans extended to the
authorized individuals. The Group has entered into certain exclusive agreements with the VIEs through Baidu
Online, which obligate Baidu Online to absorb a majority of the risk of loss from the VIEs’ activities and entitles
Baidu Online to receive a majority of their residual returns. In addition, the Group has entered into certain
agreements with the authorized individuals through Baidu Online, including loan agreements for the paid-in capital
of the VIEs, option agreements to acquire the equity interests in the VIEs when permitted by the PRC laws, and
share pledge agreements for the equity interests in the VIEs held by the authorized individuals.

Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between the
Company and VIEs through certain agreements with the authorized individuals through Baidu Online, including
loan agreements for the paid-in capital of the VIEs, option agreements to acquire the equity interests in the VIEs
when permitted by the PRC laws, and share pledge agreements for the equity interests in the VIEs held by the
authorized individuals. The equity holders of VIEs effectively assigned all of their voting rights underlying their
equity interest in VIEs to Baidu Online. In addition, through the other aforementioned agreements, the Company
demonstrates its ability and intention to continue to exercise the ability to absorb substantially all of the profits and
all of the expected losses of VIEs. The VIEs are subject to operating risks, which determine the variability of the
Company’s interest in those entities. Based on these contractual arrangements, the Company consolidates the VIEs
as required by Accounting Standards Codification (“ASC”) subtopic 810-10 (“ASC 810-10”), Consolidation:
Overall, because the Company holds all the variable interests of VIEs through Baidu Online, which is the primary
beneficiary of the VIEs.

The carrying amount of the total assets of VIEs was RMB1.19 billion (US$180.92 million) as of December 31,
2010 and there was no pledge or collateralization of their assets. The amount of the net assets of VIEs, which are
restricted under PRC laws and regulations (Note 13), was RMB341.10 million (US$51.68 million) as of
December 31, 2010.

Basis of Accounting

The consolidated financial statements have been prepared in accordance with United States generally accepted

accounting principles (“U.S. GAAP”).

Principles of Consolidation

The consolidated financial statements include the financial statements of the Company, its subsidiaries and
VIEs in which the Company holds all the variable interests of VIEs through Baidu Online. All inter-company
transactions and balances between the Company, its subsidiaries and VIEs are eliminated upon consolidation. The
Company has included the results of operations of acquired businesses from the respective dates of acquisition.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the
United States requires management to make estimates and assumptions that affect the reported amounts of assets
and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the
reported amounts of revenues and expenses during the period. Management evaluates estimates, including those

F-9

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

related to the accounts receivable allowances, fair values of options to purchase the Company’s ordinary shares, fair
values of certain equity investments, and deferred tax valuation allowance, among others. Management bases the
estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of
which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could
differ from these estimates.

Comparative Information

Certain items in prior years’ consolidated financial statements have been reclassified to conform to the current
year’s presentation in accordance with the requirement under eXtensible Business Reporting Language (“XBRL”)
to facilitate comparison.

Currency Translation for Financial Statements Presentation

Translations of amounts from RMB into US$ for the convenience of the reader have been calculated at the
exchange rate of RMB6.6000 per US$1.00 on December 30, 2010 as published on the website of the Federal
Reserve Board. No representation is made that the RMB amounts could have been, or could be, converted into
U.S. dollars at such rate.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Foreign Currency

The Company’s functional currency is the US$. The Company’s subsidiaries and VIEs determine their
functional currencies based on the criteria of ASC subtopic 830-10 (“ASC 830-10”), Foreign Currency Matters:
Overall, and have determined their functional currencies to be their respective local currency. The Company uses
the RMB as its reporting currency. The Company uses the average exchange rate for the year and the exchange rate
at the balance sheet date to translate its operating results and financial position, respectively. Any translation gains
(losses) are recorded in accumulated other comprehensive income (loss) as a component of shareholders’ equity.
Transactions denominated in foreign currencies are translated into the functional currency at the exchange rates
prevailing on the transaction dates. Assets and liabilities denominated in foreign currencies are translated into the
functional currency at the exchange rates prevailing at the balance sheet date. Exchange gains and losses are
included in the consolidated statements of income as a component of other income.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents are stated at cost, which approximates fair value, and primarily consist of cash and
investments in interest bearing demand deposit accounts, time deposits, highly liquid investments and money
market funds. All highly liquid investments with original maturities of three months or less from the date of
purchase are classified as cash equivalents.

Restricted Cash

Restricted cash consists of the cash balances deposited by the customers of the Company’s e-commerce

platform.

In 2008, the Company introduced an e-commerce platform and an online payment platform which enables
e-commerce merchants and customers to send and receive payments online. Cash balances deposited by the
customers of the Company’s e-commerce platform are considered restricted because they cannot be used for the
operations of the Group or any other purpose not designated by customers. When customers fund their accounts in

F-10

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

the e-commerce platform using their bank accounts, the deposited balance is included in the Company’s bank
account until customers either use the cash to settle their online transactions or withdraw the cash.

Investments

Short-Term Investments

All highly liquid investments with original maturities of greater than three months, but less than 12 months, are
classified as short-term investments which are stated at their approximate fair value. The Company accounts for
short-term investments in accordance with ASC subtopic 320-10 (“ASC 320-10”), Investments — Debt and Equity
Securities: Overall. The Company classifies the short-term investments in debt and equity securities as
“held-to-maturity”, “trading” or “available-for-sale”, whose classification determines the respective accounting
methods stipulated by ASC 320-10. Dividend and interest income, including amortization of the premium and
discount arising at acquisition, for all categories of investments in securities are included in earnings. Any realized
gains or losses on the sale of the short-term investments are determined on a specific identification method, and such
gains and losses are reflected in the consolidated statements of income.

The securities that the Company has positive intent and ability to hold to maturity are classified as
held-to-maturity securities and stated at amortized cost. For individual securities classified as held-to-maturity
securities, the Company evaluates whether a decline in fair value below the amortized cost basis is other than
temporary in accordance with the Company’s policy and ASC 320-10. If the Company concludes that it does not
intend or is not required to sell an impaired debt security before the recovery of its amortized cost basis, the
impairment is considered temporary and the held-to-maturity securities continue to be recognized at the amortized
costs. When the Company intends to sell an impaired debt security 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 is deemed to have occurred.
In these instances, the other-than-temporary impairment loss is recognized in the consolidated statements of income
equal to the entire excess of the debt security’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 Company does 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 cost basis,
the Company must determine whether or not it will recover its amortized cost basis. If the Company concludes that
it will not, an other-than-temporary impairment exists and that portion of the credit loss is recognized in the
consolidated statements of income, while the portion of loss related to all other factors is recognized in other
comprehensive income.

The securities that are bought and held principally for the purpose of selling them in the near term are classified

as trading securities. Unrealized holding 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 investment is reported at fair value, with unrealized gains and losses recorded in accumulated
other comprehensive income in shareholders’ equity. Realized gains or losses are charged to earnings during the
period in which the gain or loss is realized. An impairment loss on the available-for-sale debt securities would be
recognized in the consolidated statements of income when the decline in value is determined to be
other-than-temporary.

Long-term Investments

The Company’s long-term investments consist of cost method investments, equity method investments and

available-for-sale securities.

In accordance with ASC subtopic 325-20 (“ASC 325-20”), Investments-Other: Cost Method Investments, for
investments in an investee over which the Company does not have significant influence, the Company carries the
investment at cost and only adjusts for other-than-temporary declines in fair value and distributions of earnings. The

F-11

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

management regularly evaluates the impairment of the cost method investments based on performance and financial
position of the investee as well as other evidence of market value. 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 financing needs. An impairment loss is recognized in the consolidated statements of income equal to
the excess of the investment’s cost over 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 cost basis of investment.

Investments in entities in which the Company can exercise significant influence but does not own a majority
equity interest or control are accounted for using the equity method of accounting in accordance with ASC subtopic
323-10 (“ASC 323-10”), Investments-Equity Method and Joint Ventures: Overall. Under the equity method, the
Company initially records its investment at cost and adjusts the carrying amount of the investment to recognize the
Company’s proportionate share of each equity investee’s net income or loss into consolidated statements of income
after the date of acquisition. The difference between the cost of the equity investee and the amount of the underlying
equity in the net assets of the equity investee is recognized as equity method goodwill included in equity method
investment on the consolidated balance sheets. The Company evaluates the equity method investments for
impairment under ASC 323-10. An impairment loss on the equity method investments is recognized in the
consolidated statements of income when the decline in value is determined to be other-than-temporary.

The Company’s long-term investments in available-for-sale securities are the investments which are neither
classified as cost method investments nor equity method investments. In accordance with ASC 320-10,
Investments — Debt and Equity Securities: Overall, available-for-sale securities are reported at fair value, with
unrealized gains and losses recorded in accumulated other comprehensive income in shareholders’ equity. Realized
gains or losses are charged to earnings during the period in which the gain or loss is realized.

Fair Value Measurements of Financial Instruments

Financial

instruments include cash and cash equivalents, short-term investments, accounts receivable,
accounts payable and accrued liabilities, customer advances and deposits, deferred revenue, deferred income
and loans payable. The carrying amounts of these financial instruments except for loans payable approximate fair
value because of their generally short maturities. The carrying amount of loans payable approximates its fair value
due to the fact that the related interest rates are reset each year based on prevailing market interest rates.

Research, Development, and Computer Software

Capitalization of Software Developed for Internal Use

The Company has capitalized certain internal use software development costs in accordance with ASC
subtopic 350-40 (“ASC 350-40”), Intangibles-Goodwill and Other: Internal-Use Software, amounting to
RMB19.49 million, RMB12.59 million and RMB10.38 million (US$1.57 million) for the years ended
December 31, 2008, 2009 and 2010, respectively. The Company capitalizes certain costs relating to software
acquired, developed, or modified solely to meet the Company’s internal requirements and for which there are no
substantive plans to market the software. These costs mainly include payroll and payroll-related costs for
employees who are directly associated with and who devote time to the internal-use software projects during
the application development stage. Capitalized internal-use software costs are included in fixed assets, net. The
amortization expense for capitalized software costs amounted to RMB3.44 million, RMB9.77 million and
RMB8.86 million (US$1.34 million) for the years ended December 31, 2008, 2009 and 2010, respectively. The
unamortized amount of capitalized internal use software development costs was RMB26.16 million and
RMB15.28 million (US$2.32 million) as of December 31, 2009 and 2010, respectively.

F-12

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

Research and Development Expenses

Research and development expenses consist primarily of personnel-related costs. The Company has expensed
substantially all development costs included in the research and development of products and new functionality
added to the existing products as incurred, except for certain internal-use software and certain core technologies
with alternative future uses.

Fixed Assets

Fixed assets are stated at cost less accumulated depreciation. Depreciation or amortization is recorded on a
straight-line basis over the shorter of the estimated useful lives of the assets or the term of the related lease, as
follows:

Office building . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — 45 years
. . . . . . — 15 years
Office building related facility, machinery and equipment
Computer equipment . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — 3 or 5 years
Internal use software development costs . . . . . . . . . . . . . . . . . . . — 3 years
Office equipment . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — 3 or 5 years
Vehicles . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — 5 years
Leasehold improvements . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — over the shorter of lease
terms or estimated useful
lives of the assets

Fixed assets have no estimated residual value except for the office building and its related facility, machinery

and equipment, which have an estimated residual value of 4% of the cost.

Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterments
that extend the useful life of fixed assets are capitalized as additions to the related assets. Retirements, sales and
disposals of assets are recorded by removing the cost and accumulated depreciation from the asset and accumulated
depreciation accounts with any resulting gain or loss reflected in the consolidated statements of income.

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 are capitalized as construction in progress. Construction in progress is transferred to
specific fixed assets items and depreciation of these assets commences when they are ready for their intended use.

Goodwill and Intangible Assets

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets acquired in
a business combination. The Company assesses goodwill for impairment in accordance with ASC subtopic 350-20
(“ASC 350-20”), Intangibles — Goodwill and Other: Goodwill, which requires that goodwill be tested for
impairment at the reporting unit level at least annually and more frequently upon the occurrence of certain
events, as defined by ASC 350-20. Baidu’s chief operating decision maker only reviews the Company’s discrete
financials at its consolidated level and there are no segment managers who are held accountable by the Company’s
chief operating officer or anyone else, for operations, operating results, and planning for levels or components
below the consolidated level. Accordingly, consistent with the management’s operational perspective, the Company
determines that it has only one reporting unit. Goodwill was tested for impairment in the annual impairment tests on
December 31 in each year using the two-step process required by ASC 350-20. First, the Company reviewed the
carrying amount of the reporting unit compared to the “fair value” of the reporting unit based on quoted market
prices of the ordinary shares. If the fair value of the reporting unit exceeds the carrying value of the reporting unit,
goodwill is not impaired and the Company is not required to perform further testing. If the carrying value of the

F-13

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

reporting unit exceeds the fair value of the reporting unit, then the Company must perform the second step of the
impairment test in order to determine the implied fair value of the reporting unit’s goodwill. That is, the Company
would then prepare the discounted cash flow analyses. Such analyses are based on cash flow assumptions that are
consistent with the plans and estimates being used to manage the business. An excess carrying value compared to
fair value would indicate that goodwill may be impaired. Finally, if the Company determined that goodwill may be
impaired, the implied fair value of the goodwill, as defined by ASC 350-20, would be compared to its carrying
amount to determine the impairment loss, if any. There has been no impairment of goodwill in any of the years
presented.

Intangible Assets

Intangible assets with finite lives are carried at cost less accumulated amortization. The land use right is
amortized using a straight-line method over the shorter of its estimated economic life or the term of related land use
right contract. All other intangible assets with finite lives are amortized using the straight-line method over the
estimated economic life.

Intangible assets have weighted average useful lives from the date of purchase as follows:

Domain names . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — 5.0 years
Customer relationships . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — 4.9 years
Non-competition agreements . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — 3.9 years
Software . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — 5.9 years
Contract-based assets . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — 2.3 years
Trademark . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — 9.6 years
Land use right . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — 50 years

Intangible assets with an indefinite useful life are not amortized. There have been no impairment charges on

the Company’s intangible assets with finite useful lives in any of the years presented.

If the intangible assets that are not being amortized are subsequently determined to have a finite useful life, the
assets will be tested for impairment in accordance with ASC subtopic 350-30 (“ASC 350-30”), Intangibles-
Goodwill and Other: General Intangibles Other than Goodwill, and then amortized prospectively over their
estimated remaining useful lives and accounted for in the same manner as other intangible assets that are subject to
amortization. Intangible assets with indefinite useful lives are tested for impairment annually or more frequently if
events or changes in circumstances indicate that they might be impaired. There have been no impairment charges on
the Company’s intangible assets with indefinite useful lives in any of the years presented.

Impairment of Long-Lived Assets Other Than Goodwill

The Company evaluates long-lived assets, such as fixed assets and purchased or internally developed
intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate the
carrying value of an asset may not be recoverable in accordance with ASC subtopic 360-10 (“ASC 360-10”),
Property, Plant and Equipment: Overall. When such events occur, the Company assesses the recoverability of the
assets group based on the undiscounted future cash flow the assets group is expected to generate and recognizes an
impairment loss when estimated undiscounted future cash flow expected to result from the use of the assets group
plus net proceeds expected from disposition of the assets group, if any, is less than the carrying value of the assets
group. If the Company identifies an impairment, the Company reduces the carrying amount of the assets group to its
estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable
market values. The Company uses estimates and judgments in its impairment tests and if different estimates or
judgments had been utilized, the timing or the amount of any impairment charges could be different. Asset groups to
be disposed of would be reported at the lower of the carrying amount or fair value less costs to sell, and no longer

F-14

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

depreciated. The assets and liabilities of a disposal group classified as held for sale would be presented separately in
the appropriate asset and liability sections of the balance sheet.

Accounts Receivable

Accounts receivable are recognized and carried at original invoiced amount less an allowance for any potential
uncollectible amounts. An estimate for doubtful debts is made when collection of the full amount is no longer
probable. Bad debts are written off as incurred. The Company generally does not require collateral from its
customers.

The Company maintains allowances for doubtful accounts for estimated losses resulting from the failure of
customers to make payments on time. The Company reviews the accounts receivable on a periodic basis and makes
general and specific allowances when there is doubt as to the collectibility of individual balances. In evaluating the
collectibility of individual receivable balances, the Company considers many factors, including the age of the
balance, the customer’s historical payment history, its current credit-worthiness and current economic trends.

Revenue Recognition

The Company recognizes revenue based on the following principles:

Online marketing services

(1) Auction-based pay-for-performance service

The Company’s auction-based pay-for-performance (“P4P”) platform enables a customer to place its website
link and related description on the Company’s search result list. The customers make bids on keywords based on
how much they are willing to pay for each click to their listings in the search results listed on the Company’s website
and the relevance between the keywords and the customer’s businesses. Internet users’ search of the keyword will
trigger the display of the listings. The ranking of the customer’s listing depends on both the bidding price and the
listing’s relevance to the keyword searched. Customer pays the Company only when a user clicks on one of its
website links. Revenue is recognized when a user clicks on one of the customer-sponsored website links, as there is
persuasive evidence of an arrangement, the fee is fixed or determinable and collection is reasonably assured, as
prescribed by ASC subtopic 605-10 (“ASC 605-10”), Revenue Recognition: Overall.

For certain P4P customers engaged through direct sales, the Company may provide certain value-added
consultative support services to help its customers to better utilize its P4P online marketing system. Fees for such
services are recognized as revenue on a pro-rata basis over the contracted service period.

(2) Other performance-based online marketing services

To the extent the Company provides online marketing services based on performance criteria other than click-
throughs, such as the number of telephone calls brought to its customers, the number of users registered with its
customers, or the number of minimum click-throughs, revenue is recognized when the specified performance
criteria are met together with satisfaction of other applicable revenue recognition criteria as prescribed by
ASC 605-10.

(3) Time-based online advertising services

For time-based online advertising services such as text

links, banners, or other forms of graphical
advertisements, the Company recognizes revenue, in accordance with ASC 605-10, on a pro-rata basis over the
contractual term commencing on the date the customer’s advertisement is displayed in a specified webpage. For
certain time-based contractual agreements, the Company may also provide certain performance guarantees, in
which cases revenue is recognized at the later of the completion of the time commitment or performance guarantee.

(4) Online marketing services involving Baidu Union

Baidu Union is the program through which the Company expands distribution of its customers’ sponsored links
or advertisements by leveraging traffic of the Baidu Union members’ internet properties. The Company makes
payments to Baidu Union members for acquisition of traffic. The Company recognizes gross revenue for the amount
of fees it receives from its customers. Payments made to Baidu Union members are included in cost of revenues as
traffic acquisition costs.

(5) Barter transactions

The Company engages in barter transactions from time to time and in such situations follows the guidance set
forth in ASC subtopic 845-10 (“ASC 845-10”), Nonmonetary Transactions: Overall. While nonmonetary
transactions are generally recorded at fair value, if such value is not determinable within reasonable limits, the
transaction is recognized based on the carrying value of the product or services provided. The amount of revenues
recognized for barter transactions was insignificant for each of the periods presented.

In addition, the Company recognized revenues for barter transactions involving advertising in accordance with
ASC subtopic 605-20 (“ASC 605-20”), Revenue recognition: Services. However, neither the amount recognized nor
the volume of such transactions qualified for income recognition was material for any of the periods presented.

In certain instances, the Company may be granted equity instruments in exchange for services. In accordance
with ASC subtopic 505-50 (“ASC 505-50”), Equity: Equity-based Payments to Non-Employees, if the Company
provides services in exchange for equity instruments, the Company measures the fair value of those equity
instruments for revenue recognition purposes as of the earlier of either of the following dates:

(cid:129) The date the parties come to a mutual understanding of the terms of the equity-based compensation
arrangement and a commitment for performance by the Company to earn the equity instruments is reached;

(cid:129) The date at which the Company’s performance necessary to earn the equity instruments is completed.

If, as of the measurement date, the fair value of the equity instruments received is not determinable within
reasonable limits, the transaction is recognized based on the fair value of the services provided. If the fair value of
both the equity instruments received and the services provided cannot be determined, no revenue is recognized for
the services provided and the equity instrument received is recorded at zero carrying value. The amount of revenues
recognized for such transactions was insignificant in each of the years presented.

(6) Other revenue recognition related policies

If a sales arrangement involves multiple deliverables, and the arrangement is divided into separate units of
accounting in accordance with ASC subtopic 605-25 (“ASC 605-25”), Revenue recognition: Multiple-Element
Arrangements, the total revenue on such arrangement is allocated to the individual deliverables based on their
relative fair values. If sufficient vendor-specific objective evidence of fair value does not exist for the allocation of
revenue, the fee for the entire arrangement is recognized ratably over the term of the arrangement or upon the
delivery of the last deliverable, when other revenue recognition criteria have been met.

The Company delivers some of its online marketing services to end customers through engaging third party
distributors. In this context, the Company may provide cash incentives to distributors. The cash incentives are
accounted for as reduction of revenue in accordance with ASC subtopic 605-50 (“ASC 605-50”), Revenue
recognition: Customer Payments and Incentives.

The Company provides sales incentives to customers to entitle customers to receive reductions in the price of
the online marketing services by meeting certain cumulative consumption requirements. The Company accounts for
these award credits granted to members in conjunction with a current sale of products or services as a multiple-
element arrangement by analogizing to ASC 605-25. The consideration allocated to the award credits, as deferred
revenue is based on an assumption that the customer will purchase the minimum amount of future service necessary

F-16

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

to obtain the maximum award credits available. The deferred revenue is recognized as revenue proportionately as
the future services are delivered to the customer or when the loyalty points expire.

Cash received in advance from customers is recorded as customer advances and deposits. The unused cash
balances remaining in customers’ accounts are included as a liability of the Company. Deferred revenue is recorded
when services are provided before the other revenue recognition criteria set forth in ASC 605-10 are fulfilled.

The Company operates an online game platform, on which registered users could access games provided by
online game developers. The rights and obligations of each party to the arrangement indicate that the Company is
acting as an agent whereas the online game developer is the principal as a result of being the primary obligor in the
arrangement. The Company recognizes the shared revenue, on a net basis, based on the ratios pre-determined with
the online game developers when all the revenue recognition criteria set forth in ASC 605-10 are met, which is
generally when the user purchases virtual currencies issued by the game developers through the Company’s
payment channel. The amount of revenues recognized was not significant in each of the years presented.

Cost of Revenues

Cost of revenues consists primarily of business taxes and surcharges, traffic acquisition costs, bandwidth costs,

depreciation, payroll and related costs of operations.

The Company incurs business taxes and surcharges in connection with the provision of online marketing
services, technical and consultative service fees charged by Baidu Online to VIEs and other taxable services in the
PRC. According to ASC subtopic 605-45 (“ASC 605-45”), Revenue Recognition: Principal Agent Considerations,
the Company includes the business tax and surcharges incurred on its online marketing revenues in cost of revenues.
The business tax and surcharges in cost of revenues for the years ended December 31, 2008, 2009 and 2010 were
RMB200.09 million, RMB275.92 million and RMB504.85 million (US$76.49 million), respectively. Traffic
acquisition costs represent the amounts paid or payable to Baidu Union members who direct search queries to the
Company’s websites or distribute the Company’s customers’ paid links through their properties. These payments
are primarily based on revenue sharing arrangements under which the Company pays its Baidu Union members a
percentage of the fees it earns from its online marketing customers.

Advertising Expenses

Advertising expenses, primarily advertisements through various forms of media, are included in “Selling,
general and administrative expense” in the consolidated statements of income and are expensed when incurred.
Advertising expenses for the years ended December 31, 2008, 2009 and 2010 were RMB29.22 million,
RMB77.80 million and RMB74.76 million (US$11.33 million), respectively.

Other Income, net

Other income, net consists primarily of interest income, government subsidies, impairment of long-term
investments and non-operating expenses. Interest income is mainly generated from bank deposits and other interest-
earning financial assets and is recognized on an accrual basis. Other income, net primarily consists of financial
subsidies received from provincial and local governments for operating a business in their jurisdictions and
compliance with specific policies promoted by the local governments. During the years ended December 31, 2008,
2009 and 2010,
the Group received financial subsidies of RMB22.72 million, RMB42.50 million and
RMB49.14 million (US$7.45 million), respectively, from various local PRC government authorities. There are
no defined rules and regulations to govern the criteria necessary for companies to receive such benefits, and the
amount of financial subsidy is determined at the discretion of the relevant government authorities. Such amounts are
recorded as other income when received and there are no further conditions to be met before recognition.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

Leases

Leases have been classified as either capital or operating leases. Leases that transfer substantially all the
benefits and risks incidental 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 the lease. All other leases are accounted for as operating leases
wherein rental payments are expensed as incurred. The Company had no capital leases for the years ended
December 31, 2008, 2009 and 2010.

Income Taxes

The Company recognizes income taxes under the liability method. Deferred income taxes are recognized for
differences between the financial reporting and tax bases of assets and liabilities at enacted tax rates in effect for the
years in which the differences are expected to reverse. The Company records a valuation allowance against the
amount of deferred tax assets that it determines is not more likely than not being realized. The effect on deferred
taxes of a change in tax rates is recognized in income in the period that includes the enactment date.

The Company adopted the provisions of ASC subtopic 740-10 (“ASC 740-10”), Income Taxes: Overall, on
January 1, 2007. ASC 740-10 clarified the accounting for uncertainty in income taxes by prescribing the recognition
threshold a tax position is required to meet before being recognized in the financial statements. The Company has
elected to classify interest and penalties related to an uncertain tax position (if and when required) as part of income
tax expense in the consolidated statements of income. As of and for the years ended December 31, 2008, 2009 and
2010, no unrecognized tax benefits or interest and penalties associated with uncertainty in income taxes have been
recognized.

Share-based Compensation

The Company adopted ASC subtopic 718-10 (“ASC 718-10”), Compensation-Stock Compensation: Overall,
using the modified prospective transition approach from January 1, 2006. Pursuant to ASC 718-10, the Company
recognized share-based compensation expense over the requisite service periods for any share-based awards
granted after January 1, 2006 based on the fair values of all share-based awards on the dates of grant.

The Company has elected to recognize share-based compensation after the date of adoption of ASC 718-10
using the straight-line method for all share-based awards issued. Forfeitures have been estimated based on historical
experience and periodically reviewed. Cancellation of an award accompanied by the concurrent grant of a
replacement award is accounted for as a modification of the terms of the cancelled award (“modification
awards”). The compensation costs associated with the modification awards are recognized if either the original
vesting condition or the new vesting condition has been achieved. Such compensation costs cannot be less than the
grant-date fair value of the original award. The incremental compensation cost is measured as the excess of the fair
value of the replacement award over the fair value of the cancelled award at the cancellation date. Therefore, in
relation to the modification awards, the Company recognizes share-based compensation over the vesting periods of
the new options, which comprises, (1) the amortization of the incremental portion of share-based compensation
over the remaining vesting term and (2) any unrecognized compensation cost of original award, using either the
original term or the new term, whichever is higher for each reporting period.

The Company accounts for share awards issued to non-employees in accordance with the provisions of ASC
subtopic 505-50 (“ASC 505-50”), Equity: Equity-based Payments to Non-Employees. Under ASC 505-50, the
Company uses the Black-Scholes option pricing model method to measure the value of options granted to non-
employees at each vesting date to determine the appropriate charge to share-based compensation. ASC 718-10 also
requires share-based compensation to be presented in the same manner as cash compensation rather than as a
separate line item.

BAIDU, INC.

Earnings Per Share (“EPS”)

The Company computes earnings per Class A and Class B ordinary shares in accordance with ASC subtopic
260-10 (“ASC 260-10”), Earnings Per Share: Overall, using the two class method. Under the provisions of
ASC 260-10, basic net income per share is computed using the weighted average number of ordinary shares
outstanding during the period except that it does not include unvested ordinary shares subject to repurchase or
cancellation. Diluted net income per share is computed using the weighted average number of ordinary shares and,
if dilutive, potential ordinary shares outstanding during the period. Potentially dilutive securities have been
excluded from the computation of diluted net income per share if their inclusion is anti-dilutive. Potential ordinary
shares consist of the incremental ordinary shares issuable upon the exercise of stock options, restricted shares
subject to forfeiture, and contracts that may be settled in the Company’s stock or cash. The dilutive effect of
outstanding stock options and restricted shares is reflected in diluted earnings per share by application of the
treasury stock method. The computation of the diluted net income per share of Class A ordinary shares assumes the
conversion of Class B ordinary shares, while the diluted net income per share of Class B ordinary shares does not
assume the conversion of those shares.

The liquidation and dividend rights of the holders of the Company’s Class A and Class B ordinary shares are
identical, except with respect to voting. As a result, and in accordance with ASC subtopic 260-10 (“ASC 260-10”),
Earnings Per Share: Overall, the undistributed earnings for each year are allocated based on the contractual
participation rights of the Class A and Class B ordinary shares as if the earnings for the year had been distributed. As
the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis.
Further, as the conversion of Class B ordinary shares is assumed in the computation of the diluted net income per
share of Class A ordinary shares, the undistributed earnings are equal to net income for that computation.

For the purposes of calculating the Company’s basic and diluted earnings per Class A and Class B ordinary
shares, the ordinary shares relating to the options that were exercised are assumed to have been outstanding from the
date of exercise of such options.

Concentration of Risks

Concentration of credit risk

Financial instruments that potentially subject the Company to significant concentration of credit risk primarily
consist of cash and cash equivalents, restricted cash, short-term investments and accounts receivable. The Company
has RMB8.20 billion (US$1.24 billion) in cash and cash equivalents, restricted cash and short-term investments.
The Company has approximately RMB8.06 billion (US$1.22 billion) in cash, bank deposits and money market
funds in the PRC, which constitute about 98.29% of total cash and cash equivalents and short-term investments. In
the event of bankruptcy of one of the financial institutions in which the Company has deposits or investments, it may
be unlikely to claim its deposits or investments back in full.

Accounts receivable are typically unsecured and derived from revenue earned from customers and agents in
China, which are exposed to credit risk. The risk is mitigated by credit evaluations the Company performs on its
customers and its ongoing monitoring process of outstanding balances. The Company maintains reserves for
estimated credit losses and these losses have generally been within its expectations.

Business and economic risks

The Company participates in a dynamic high technology industry and believes that changes in any of the
following areas could have a material adverse effect on the Company’s future financial position, results of
operations or cash flows: changes in the overall demand for services and products; changes in business offerings;
competitive pressures due to new entrants; advances and new trends in new technologies and industry standards;
changes in bandwidth suppliers; changes in certain strategic relationships or customer relationships; regulatory

F-19

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

considerations; copyright regulations; and risks associated with the Company’s ability to attract and retain
employees necessary to support its growth.

No customer or any Baidu Union member generated greater than 10% of total revenues in any of the periods

presented.

The Company’s operations could be adversely affected by significant political, economic and social

uncertainties in the PRC.

Currency convertibility risk

Substantially all of the Company’s businesses are transacted in RMB, which is not freely convertible into
foreign currencies. All foreign exchange transactions take place either through the People’s Bank of China or other
banks authorized to buy and sell foreign currencies at the exchange rates quoted by the People’s Bank of China.
Approval of foreign currency payments by the People’s Bank of China or other regulatory institutions requires
submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts.

Foreign currency exchange rate risk

The Company’s exposure to foreign currency exchange rate risk primarily relates to cash and cash equivalents
and short-term investments denominated in the U.S. dollar. The functional currency of the Company is US$, and the
reporting currency is RMB. Since July 21, 2005, the RMB has been permitted to fluctuate within a narrow and
managed band against a basket of certain foreign currencies. On June 19, 2010, the People’s Bank of China
announced the end of the RMB’s de facto peg to US$, a policy which was instituted in late 2008 in the face of the
global financial crisis, to further reform the RMB exchange rate regime and to enhance the RMB’s exchange rate
flexibility. The exchange rate floating bands will remain the same as previously announced in the inter-bank foreign
exchange market. The depreciation of the US$ against RMB was approximately 3.31% in 2010. Any significant
revaluation of RMB may materially and adversely affect the Company’s cash flows, revenues, earnings and
financial position, and the value of, and any dividends payable on, the ADS in U.S. dollars. As a result, an
appreciation of RMB against the U.S. dollar would result in foreign currency translation losses when translating the
net assets of the Company from the U.S. dollar into RMB.

The functional currency of the subsidiaries in Japan is Japanese Yen (“JPY”), and the reporting currency is
RMB. During 2010, JPY appreciated by approximately 10.23% against RMB. The appreciation of JPY against
RMB results in foreign currency translation gains when translating the net assets into RMB.

For the years ended December 31, 2008, 2009 and 2010, the net foreign currency translation loss resulting from
the translation from the respective functional currencies to the RMB reporting currency recorded in the Company’s
other comprehensive loss was RMB27.60 million, RMB3.96 million and RMB3.87 million (US$0.59 million),
respectively.

Recent Accounting Pronouncements

In October 2009, the FASB issued ASU No. 2009-13 (“ASU 2009-13”), Multiple-Deliverable Revenue
Arrangements. ASU 2009-13 amends ASC sub-topic 605-25 (“ASC 605-25”), Revenue Recognition: Multiple-
Element Arrangements, regarding revenue arrangements with multiple deliverables. This standard addresses how to
determine whether an arrangement involving multiple deliverables contains more than one unit of accounting, and
how the arrangement consideration should be allocated among the separate units of accounting. This standard
establishes a selling price hierarchy for determining the selling price of a deliverable, which is based on: (a) vendor-
specific objective evidence; (b) third-party evidence; or (c) estimated selling price. This standard also eliminates the
residual method of allocation and requires that arrangement consideration be allocated at the inception of the
arrangement to all deliverables using the relative selling price method. In addition, this standard significantly
expands required disclosures related to a vendor’s multiple-deliverable revenue arrangements. This standard is

F-20

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

effective for fiscal years beginning after June 15, 2010 and to be applied retrospectively or prospectively for new or
materially modified arrangements. In addition, early adoption is permitted. The Company will adopt ASU 2009-13
beginning January 1, 2011 and the Company is in the process of assessing the impact of the adoption of the standard
on its consolidated financial statements.

In April 2010, the FASB issued ASU No. 2010-13 (“ASU 2010-13”), Compensation-Stock Compensation
(“ASC 718”): Effect of Denominating the Exercise Price of a Share-Based Payment Award in the Currency of the
Market in Which the Underlying Equity Security Trades. The objective of this standard is to address the
classification of an employee share-based payment award with an exercise price dominated in the currency of
a market in which the underlying equity security trades. ASC 718 provides guidance on the classification of a share-
based payment award as either equity or liability. A share-based payment award that contains a condition that is not
a market, performance, or service condition is required to be classified as a liability. ASU 2010-13 provide
amendments to ASC 718 to clarify that an employee share-based payment award with an exercise price
denominated in the currency of a market in which a substantial portion of the entity’s equity securities trades
should not be considered to contain a condition that is not a market, performance, or service condition. Therefore,
an entity would not classify such an award as a liability if it otherwise qualifies as equity. Then amendments in this
standard are effective for fiscal years, and interim periods within those fiscal years, beginning on or after
December 31, 2010. Early application is permitted. The Company does not expect the adoption of ASU
2010-13 will have a material impact on its consolidated financial statements.

In December 2010, the FASB issued ASU No. 2010-28 (“ASU 2010-28”), Intangibles — Goodwill and Other
(“ASC 350”): When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative
Carrying Amounts. The objective of this standard is to address questions about entities with reporting units with
zero or negative carrying amounts because some entities concluded that Step 1 of the test is passed in those
circumstances because the fair value of their reporting unit will generally be greater than zero. The amendments in
this standard modify Step 1 of the goodwill impairment test for reporting units with zero or negative carrying
amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is
more likely than not that a goodwill impairment exists. This standard is effective for fiscal years, and interim periods
within those years, beginning after December 15, 2010. Early adoption is not permitted. The Company does not
expect the adoption of ASU 2010-28 will have a material impact on its consolidated financial statements.

In December 2010, the FASB issued ASU No. 2010-29 (“ASU 2010-29”), Disclosure of Supplementary Pro
Forma Information for Business Combinations (“ASC 805”). The objective of this standard is to address diversity in
practice about the interpretation of the pro forma revenue and earnings disclosure requirements for business
combinations. This standard specifies that if a public entity presents comparative financial statements, the entity
should disclose revenue and earnings of the combined entity as though the business combination(s) that occurred
during the current year had occurred as of the beginning of the comparable prior annual reporting period only. This
standard also expands the supplemental pro forma disclosures under ASC 805 to include a description of the nature
and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination
included in the reported pro forma revenue and earnings. This standard is effective prospectively for business
combinations for which the acquisition date is on or after the beginning of the first annual reporting period
beginning on or after December 15, 2010. Early adoption is permitted. The Company does not expect the adoption
of ASU 2010-29 will have a material impact on its consolidated financial statements.

Long-term investments

The Company’s long-term investments consist of cost method investments, equity method investments and

available-for-sale securities.

Long-term available-for-sale securities

The Company’s long-term investments in available-for-sale securities are investments which are neither

classified as cost method investments nor equity method investments.

In May 2010, the Company acquired 4,942,784 series A-1 convertible redeemable preferred shares of
6DXchange Inc. with a total cash consideration of US$3.79 million. The Company holds 11.60% of equity
interests of 6DXchange on an as-converted basis. In accordance with ASC 320-10, investments in securities which
are redeemable at the option of the investor are considered debt securities. The investment in 6DXchange Inc. was
classified as available-for-sale debt securities because it was not classified as either held-to-maturity or trading
securities as the convertible redeemable preferred shares have no stated maturity date and the Company does not
have the intent to sell it in the near term. As the Company does not expect to sell or redeem it within one year and has
the intent to hold it for long-term returns, the investment is classified as long-term available-for-sale securities.

As of December 31, 2010, the fair value of long-term investments in available-for sale securities approximates

the cost of the investment of US$3.79 million. For further information, see Note 18.

F-22

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

Cost method investments

The Company’s carrying amount of cost method investments was RMB12.29 million and RMB204.35 million
(US$30.96 million) as of December 31, 2009 and 2010, respectively. The increase is primarily due to the investment
in the ordinary shares of a privately-held, PRC-based home furnishing E-commerce company in 2010, in which the
Company does not have significant influence. The impairment charges on cost method investments were
RMB7.99 million, nil and nil for the years ended December 31, 2008, 2009 and 2010, respectively.

Equity method investments

In July 2009, Beijing Perusal, together with Paibo Online (Beijing) Technology Co., Ltd. (“Paibo”), a
subsidiary of Beijing News, set up a joint venture, Beijing Paibo Times Technology Co., Ltd. (“Paibo Times”), to
operate a community website and provide information of interest to Beijing local residents. The registered capital of
Paibo Times is RMB5.34 million (US$0.81 million). The Company holds 42.12% equity interest in Paibo Times
and accounts for the investment under the equity method.

In February 2010, the Company, Providence Equity Partners (“Providence”), and Dragon Ventures Limited
(“Dragon”) signed an agreement, pursuant to which Providence and Dragon agreed to acquire US$50.00 million in
convertible redeemable preferred shares and US$1.00 million in convertible preferred shares, respectively, of
Qiyi.com, Inc., a Cayman Islands company established by the Company. Qiyi.com, Inc., and entities under its
control, develop and operate an advertising supported online video business. The Company accounts for the
investment in Qiyi.com, Inc. under the equity method despite holding 100% of its common shares due to certain
substantive participating rights provided to the convertible redeemable preferred shareholder.

On January 27, 2010, the Company signed an agreement with Rakuten, Inc. (“Rakuten”), an e-commerce
website in Japan, to establish a joint venture, RakuBai Limited, to build a B2B2C online shopping mall for PRC
Internet users. B2B2C refers to an online marketplace that links and provides value-added services to both business
to business and business to consumer. On February 12, 2010, RakuBai Limited was incorporated in Hong Kong. The
registered capital of RakuBai Limited is US$20.0 million. The Company holds 49% equity interest in RakuBai
Limited and accounts for the investment under the equity method.

On August 25, 2010, Baidu Netcom, together with Chongqing Yubao Culture Communication Co., Ltd.
(“Yubao”), Chongqing Service News Office (“Service News”) and a third party individual, established Chongqing
Rongdu Technology Co., Ltd. (“Chongqing Rongdu”) to operate a community website and provide daily
information of interest
residents. The registered capital of Chongqing Rongdu is
RMB2.50 million (USD$0.38 million). Baidu Netcom, Yubao, Service News and the third party individual
hold 40%, 30%, 15% and 15% of the JV’s equity interest, respectively. The Company accounts for its investment in
Chongqing Rongdu under the equity method.

to Chongqing local

On December 22, 2010, Henan Ruizhiqi Information Technology Co., Ltd. (“Henan Ruizhiqi”), a third party
company, transferred its 40% of the equity interest in Henan Feidian Network Technology Co., Ltd. (“Henan
Feidian”) to Baidu Netcom at the nominal amount of RMB1.00 (USD$0.15). Henan Feidian operates a community
website and provides daily information of interest to Henan local residents. The registered capital of Henan Feidian
is RMB2.00 million (US$0.30 million). Baidu Netcom, Henan Ruizhiqi, Henan Business News and a third party
individual hold 40%, 10%, 35% and 15% of Henan Feidian’s equity interest, respectively. The Company accounts
for its investment in Henan Feidian under the equity method. Henan Feidian had limited operation as of
December 31, 2010.

There was no impairment loss recognized for the years ended December 31, 2008, 2009 and 2010.

INCOME TAXES

The Company is incorporated in the Cayman Islands and conducts its primary business operations through the
subsidiaries and VIEs in the PRC and Japan. It also has intermediate holding companies in the British Virgin Islands
(“BVI”) and Hong Kong. Under the current laws of the Cayman Islands and BVI, the Company is not subject to tax
on income or capital gains. Additionally, upon payments of dividends by the Company to its shareholders, no

F-27

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

Cayman Islands and BVI withholding tax will be imposed. Under the Hong Kong tax laws, Baidu Hong Kong is
exempted from income tax on its foreign-derived income and there are no withholding taxes in Hong Kong on
remittance of dividends.

China

Under the current EIT Law which has been effective since 2008, domestic enterprises and Foreign Investment
Enterprises (the “FIE”) are subject to a unified 25% enterprise income tax rate, except for certain entities that
enjoyed the tax holidays.

An enterprise recognized as a qualified “High and New Technology Enterprise” (“HNTE”) after 2008 is
granted the preferential EIT rate of 15%. If an enterprise, which was recognized as a “HNTE” before 2008, is also
verified as a HNTE after 2008, it is entitled to its remaining tax holiday granted before 2008 and a preferential EIT
rate of 15% upon expiration of the tax holiday thereafter. In accordance with tax circular Guoshuihan [2010]
No. 157, a qualified HNTE which is in the transitional period of the preferential reduction of tax rates may choose to
enjoy a subsequent 50% reduction on the transitional tax rate, or a preferential EIT rate of 15% without further 50%
reduction.

A qualified “Software Enterprise” is entitled to 2-year exemption and subsequent 50% tax rate reduction for
3 years. If the applicable preferential EIT rate for a ‘‘ Software Enterprise” before 2008 is 15%, it enjoys gradual
increase in tax rate from 2008 to 2012, specifically, 18% in 2008, 20% in 2009, 22% in 2010, 24% in 2011, and 25%
in 2012 according to Guofa [2007] No. 39. Thus, if an enterprise was recognized as a qualified “Software
Enterprise” before 2008 and still retains this qualification after 2008, the tax exemptions and deductions enjoyed by
the qualified “Software Enterprise” are based on the applicable tax rates.

Baidu Online, recognized as a qualified “HNTE” after 2008, has enjoyed the preferential EIT rate of 15% from

2008.

Baidu Times, a qualified “HNTE” before 2008, was granted prior to the effectiveness of the current EIT Law,
tax holidays for several years, that is, a 3-year tax exemption from 2006 to 2008, and a subsequent 50% tax
reduction on the transitional tax rate for 2 years from 2009 to 2010, namely, 10% in 2009 and 11% in 2010.

Baidu China, was recognized as a qualified “Software Enterprise” before 2008 and still retains this
qualification after 2008, and thus is entitled to 2-year exemption from 2006 to 2007 and subsequent 50% tax
rate reduction for 3 years from 2008 to 2010 at 9% in 2008, 10% in 2009, and 11% in 2010.

Under the current EIT Law, dividends paid by a FIE to any of its foreign non-resident enterprise investors are
subject to a 10% withholding tax. Thus, the dividends, if and when payable by Baidu Online to Baidu BVI, would be
subject to 10% withholding tax. A lower tax rate will be applied if such foreign non-resident enterprise investor’s
jurisdiction of incorporation has signed a tax treaty or arrangement for the avoidance of double taxation and the
prevention of fiscal evasion with respect to taxes on income with China. There is such a tax arrangement between
PRC and Hong Kong. Thus, the dividends, if and when payable by Baidu Times and Baidu China to Baidu HK,
would be subject to 5% withholding tax rather than statutory rate of 10% provided that Baidu HK meets the
requirements stipulated by relevant PRC tax regulations. Furthermore, pursuant to the applicable circular and
interpretations of the current EIT Law, dividends from earnings created prior to 2008 but distributed after 2008 are
not subject to withholding income tax.

Moreover, the current EIT Law treats enterprises established outside of China with “effective management and
control” located in China as PRC resident enterprises for tax purposes. The term “effective management and
control” is generally defined as exercising overall management and control over the business, personnel,
accounting, properties, etc. of an enterprise. The Company, if considered a PRC resident enterprise for tax
purposes, would be subject to the PRC Enterprise Income Tax at the rate of 25% on its worldwide income for the

period after January 1, 2008. As of December 31, 2010, the Company has not accrued for PRC tax on such basis.
The Company will continue to monitor its tax status.

Japan

Baidu Japan with a paid-in capital in excess of JPY100.00 million is subject to national income tax of 30%.
Baidu Japan is also subject to inhabitants tax, assessed by both prefectures and municipalities. Inhabitants tax is
computed as a percentage of national income tax. The per capita tax is based on the Company’s capitalization and
the number of employees. In addition, Baidu Japan is subject to a corporate enterprise tax on a pro forma basis based
on the amount of taxable profit subject to the corporate tax, added-value components, (e.g. labor costs, net interest
and rental payments, income/loss for current year) and a capital component. Baidu Japan has been in a cumulative
loss position since its inception.

The Company had minimal operations in jurisdictions other than the PRC. Income (loss) before income taxes

The Company does not believe that sufficient positive evidence exists to conclude that the recoverability of
Baidu Japan’s net deferred tax assets is more likely than not to be realized. Consequently, the Company has
provided full valuation allowances on the related net deferred tax assets.

As of December 31, 2010, the Company had net operating losses of approximately RMB461.00 million
(US$69.85 million) from Baidu Japan, Baidu HK and PRC entities, which can be carried forward to offset future net

BAIDU, INC.

profit for income tax purposes. The Japan net operating loss will expire beginning 2015; the PRC net operating loss
will expire beginning 2014; and the HK net operating loss can be carried forward without an expiration date.

The Company has evaluated its income tax uncertainty under ASC 740-10. ASC 740-10 clarifies the
accounting for uncertainty in income taxes by prescribing the recognition threshold a tax position is required
to meet before being recognized in the financial statements. The Company has elected to classify interest and
penalties related to an uncertain tax position, if and when required, as part of income tax expense in the consolidated
statements of operations. As of December 31, 2010, there is no significant tax uncertainty impact on the Company’s
financial position and result of operations.

The Company did not provide for deferred income taxes and foreign withholding taxes on the undistributed
earnings of foreign subsidiaries as of December 31, 2009 and 2010 on the basis of its intent to permanently reinvest
foreign subsidiaries’ earnings. If these foreign earnings were to be repatriated in the future, the related tax liability
may be reduced by any foreign income taxes previously paid on these earnings. Determination of the amount of
unrecognized deferred tax liability related to these earnings is not practicable. In the case of its VIEs, undistributed
earnings were insignificant as of each of the balance sheet dates.

In general, the PRC and Japanese tax authorities have up to five and seven years respectively to conduct
examinations of the Company’s tax filings. Accordingly, the PRC subsidiaries’ tax years 2007-2010 and the
Japanese subsidiary’s tax years 2007-2010 remain open to examination by the respective taxing jurisdictions.

10. LOANS PAYABLE, NONCURRENT

On October 27, 2010, Baidu Netcom borrowed a loan from the Export-Import Bank of China to finance some
of its government-sponsored research projects, at the annual interest rate of 5.60%, with respect to which the
government will provide a cash subsidy at the amount that approximates the interest of the loan. The commitment of
the unsecured bank loan amounts to RMB140.00 million (US$21.21 million) and can be borrowed from time to time
within 3 years. As of December 31, 2010, Baidu Netcom borrowed RMB86.00 million (US$13.03 million) under
the commitment. The loan will be repaid according to the following schedule from July 30, 2012. Baidu Netcom has
the right to repay and may terminate the loan upon a notice in advance.

11. EMPLOYEE DEFINED CONTRIBUTION PLAN

Full time employees of the Group in the PRC participate in a government mandated multi-employer defined
contribution plan pursuant to which certain pension benefits, medical care, unemployment insurance, employee
housing fund and other welfare benefits are provided to employees. Chinese labor regulations require that the Group
make contributions to the government for these benefits based on certain percentages of the employees’ salaries.
The Company has no legal obligation for the benefits beyond the contributions. The total amounts for such
employee benefits, which were expensed as incurred, were RMB98.18 million, RMB141.84 million and
RMB218.88 million (US$33.16 million) for the years ended December 31, 2008, 2009 and 2010, respectively.

12. COMMITMENTS AND CONTINGENCIES

Capital commitments

The Company’s capital commitments relate primarily to expenditures on computer equipment and the
consideration in relation to a business combination that will be closed in 2011. Total capital commitments
contracted but not yet reflected in the financial statements amounted to RMB168.40 million (US$25.52 million) at
December 31, 2010. All of these capital commitments are to be fulfilled within the next year.

Operating lease commitments

The Company leases facilities in the PRC under non-cancelable operating leases expiring on different dates.
Payments under operating leases are expensed on a straight-line basis over the periods of the respective leases. Total
rental expense under all operating leases was RMB68.86 million, RMB84.43 million and RMB76.87 million
(US$11.65 million) for the years ended December 31, 2008, 2009 and 2010, respectively.

Guarantees

The Company accounts for guarantees in accordance with ASC subtopic 460-10 (“ASC 460-10”), Guarantees:
Overall. Accordingly, the Company evaluates its guarantees to determine whether (a) the guarantee is specifically
excluded from the scope of ASC 460-10, (b) the guarantee is subject to ASC 460-10 disclosure requirements only,
but not subject to the initial recognition and measurement provisions, or (c) the guarantee is required to be recorded
in the financial statements at fair value.

The corporate by-laws require that the Company indemnify its officers and directors, as well as those who act
as directors and officers of other entities at the Company’s request, against expenses, judgments, fines, settlements
and other amounts actually and reasonably incurred in connection with any proceedings arising out of their services
to the Company. In addition, the Company has entered into separate indemnification agreements with each director
and each executive officer of the Company that provide for indemnification of these directors and officers under
similar circumstances and under additional circumstances. The indemnification obligations are more fully
described in the by-laws and the indemnification agreements. The Company purchases standard directors and
officers insurance to cover claims or a portion of the claims made against its directors and officers. Since a
maximum obligation is not explicitly stated in the Company’s by-laws or in the indemnification agreements and
will depend on the facts and circumstances that arise out of any future claims, the overall maximum amount of the
obligations cannot be reasonably estimated.

Historically, the Company has not been required to make payments related to these obligations, and the fair

value for these obligations is zero in the consolidated balance sheets as of December 31, 2009 and 2010.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

Baidu Online has unconditionally guaranteed the repayment of RMB-denominated bank loans from Export-
Import Bank of China and related interest and fees of Baidu Netcom. The guarantees continue until the loans,
including accrued interest and fees, have been repaid in full. These guarantees expire in 2012. The maximum
exposure to the Company under this commitment is RMB140.00 million (US$21.21 million) as of December 31,
2010 and is limited to the sum of unpaid principal and interest, as well as other related expenses.

Litigation

Baidu Netcom, Baidu China, Baidu Online and Baidu Times were involved in certain cases pending in various
PRC courts and arbitration as of December 31, 2010. These cases include copyright infringement cases, unfair
competition cases, and defamation cases, among others. Adverse results in these lawsuits may include awards of
damages and may also result in, or even compel, a change in the Company’s business practices, which could result
in a loss of revenue or otherwise harm the business of the Company.

As of December 31, 2010, the plaintiffs claimed compensation of RMB132.95 million (US$20.14 million).
Although the results of litigation and claims cannot be predicted with certainty, the Company does not expect the
outcome of the matters discussed above will result in a material adverse effect on its business, consolidated financial
position, results of operations or cash flows.

13. SHAREHOLDERS’ EQUITY

Ordinary shares

Upon completion of the Company’s initial public offering (“IPO”) in August 2005, 16,648,877 Class B
Ordinary shares were issued upon conversion of all convertible preferred shares. In addition, immediately following
the closing of the IPO, the Memorandum and Articles of Association were amended and restated such that the
authorized share capital consisted of 870,400,000 ordinary shares at a par value of US$0.00005 per share, of which
825,000,000 shares were designated as Class A ordinary shares, 35,400,000 as Class B ordinary shares, and
10,000,000 shares designated as preferred shares. The rights of the holders of Class A and Class B ordinary shares
are identical, except with respect to voting and conversion rights. Each share of Class A ordinary shares is entitled to
one vote per share and is not convertible into Class B ordinary shares under any circumstances. Each share of
Class B ordinary shares is entitled to ten votes per share and is convertible into one Class A ordinary share at any
time by the holder thereof. Upon any transfer of Class B ordinary shares by the holder thereof to any person or entity
that is not an affiliate of such holder, such Class B ordinary shares would be automatically converted into an equal
number of Class A ordinary shares. There were 122,856, 419,654 and 650,000 Class B ordinary shares transferred to
Class A ordinary shares in 2008, 2009 and 2010, respectively.

As of December 31, 2010 there were 27,045,340 and 7,804,332 Class A and Class B ordinary shares
outstanding, respectively. As of December 31, 2009 and 2010, there were no preferred shares issued and
outstanding.

Comprehensive Income

Comprehensive income is defined as the change in equity of the Company during a period from transactions
and other events and circumstances excluding transactions resulting from investments by owners and distributions
to owners. Comprehensive income is reported in the consolidated statements of shareholders’ equity. Accumulated
other comprehensive income (loss) of the Company consists of foreign currency translation adjustments.

Retained earnings

In accordance with the Regulations on Enterprises with Foreign Investment of China and their articles of
association, the Company’s PRC subsidiaries, being foreign invested enterprises established in China, are required
to make appropriations to certain statutory reserves, namely a general reserve fund, an enterprise expansion fund, a

F-33

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

staff welfare fund and a bonus fund, all of which are appropriated from net profit as reported in their PRC statutory
accounts. Each of the Company’s subsidiaries is required to allocate at least 10% of its after-tax profits to a general
reserve fund until such fund has reached 50% of its respective registered capital. Appropriations to the enterprise
expansion fund and staff welfare and bonus funds are at the discretion of the board of directors of the Company’s
subsidiaries.

In accordance with the China Company Laws, the Company’s VIEs must make appropriations from their after-
tax profits as reported in their PRC statutory accounts to non-distributable reserve funds, namely a statutory surplus
fund, a statutory public welfare fund and a discretionary surplus fund. Each of the Company’s VIEs is required to
allocate at least 10% of its after-tax profits to the statutory surplus fund until such fund has reached 50% of its
respective registered capital. Appropriation to the statutory public welfare fund is 5% to 10% of the after-tax profits
as reported in the PRC statutory accounts. Effective from January 1, 2006, under the revised China Company Laws,
appropriation to the statutory public welfare fund is no longer mandatory. Appropriations to the discretionary
surplus fund are made at the discretion of the Company’s VIEs.

General reserve and statutory surplus funds are restricted to set-off against losses, expansion of production and
operation and increasing registered capital of the respective company. Staff welfare and bonus fund and statutory
public welfare funds are restricted to capital expenditures for the collective welfare of employees. The reserves are
not allowed to be transferred to the Company in terms of cash dividends, loans or advances, nor are they allowed for
distribution except under liquidation.

15. SHARE-BASED AWARDS PLAN

Incentive Compensation Plans

In January 2000, the Company adopted the 2000 Option Plan (the “2000 Plan”). The 2000 Plan provided for
the granting of share options and restricted ordinary shares to employees and consultants of the Company. All the
options granted to Company employees and consultants under the 2000 Plan were nonqualified share options
(“NSO”). The Company reserved 5,040,000 ordinary shares for issuance under the 2000 Plan. Under the 2000 Plan,
which has expired during 2010, options granted generally vest 25% after the first year of service and ratably each
month over the remaining 36-month period.

In December 2008, the Company amended the 2000 Plan by adding a new section regarding adjustment of
exercise price. The exercise price per share subject to an option might be amended or adjusted in the absolute
discretion of the 2000 Plan administrator, which was the Board of Directors, and the determination of which should
be final, binding and conclusive. A downward adjustment of the exercise prices should be effective without the
approval of the Company’s shareholders or the approval of the affected grantees.

In December 2008, the Company adopted a share incentive plan (the “2008 Plan”). The 2008 Plan provides for
the granting of share incentives, which include incentive share option (“ISO”), restricted shares and any other form
of award pursuant to the 2008 Plan, to members of the board, employees and consultants of the Company. However,
the Company may grant ISOs only to its employees. The Company has reserved 3,428,777 ordinary shares for
issuance under the 2008 Plan, which will expire in the year 2018. The vesting schedule, time and condition to
exercise options will be determined by the compensation committee. The term of the options may not exceed ten
years from the date of the grant, except that five years is the maximum term of an ISO granted to an employee who
holds more than 10% of the voting power of the Company’s share capital.

Under the 2008 Plan, the exercise price per share subject to an option may be amended or adjusted at the
discretion of the compensation committee, the determination of which shall be final, binding and conclusive. To the
extent not prohibited by applicable laws or exchange rules, a downward adjustment of the exercise prices shall be
effective without the approval of the Company’s shareholders or the approval of the affected grantees. If the
Company grants an ISO to an employee who, at the time of that grant, owns shares representing more than 10% of
the voting power of all classes of the Company’s share capital, the exercise price cannot be less than 110% of the fair
market value of the Company’s ordinary shares on the date of that grant.

Starting from February 15, 2006, the Company has granted restricted Class A ordinary shares (“Restricted
Shares”) of the Company. Terms for Restricted Shares are the same as share options except that Restricted Shares do
not require exercise and have a two to four years vesting term.

The aggregate intrinsic value in the table above represents the difference between the Company’s closing stock

price on the last trading day in 2010 and the exercise price.

Total intrinsic value of options exercised for the three years ended December 31, 2008, 2009 and 2010 was

RMB465.25 million, RMB340.13 million and RMB263.97 million (US$40.00 million), respectively.

As of December 31, 2010, there was RMB51.32 million (US$7.78 million) unrecognized share-based
compensation cost related to share options. That deferred cost is expected to be recognized over a weighted-
average vesting period of 2.90 years. To the extent the actual forfeiture rate is different from original estimate, actual
share-based compensation costs related to these awards may be different from the expectation.

On February 11, 2009, the Company cancelled options previously granted to certain executives with the
exercise price significantly higher than the fair market value at that time, and concurrently re-granted the same
number of options at the then current fair market value. The vesting of the replacement option starts from the date of
grant, and all other terms remain the same as the original option. The cancellation and re-grant was intended to
provide incentives for these executives. In accordance with ASC 718-10, the Company accounted for the
cancellation of an award accompanied by the concurrent grant of a replacement award as a modification of the
terms of the cancelled award. Therefore, incremental compensation cost was measured as the excess of the fair
value of the replacement award over the fair value of the cancelled award at the cancellation date. The incremental
cost resulting from the cancellation and replacement was US$0.60 million. The cost is being amortized on a
straight-line basis over the vesting term of four years of the replacement option.

BAIDU, INC.

As of December 31, 2010, there was RMB162.53 million (US$24.63 million) unrecognized share-based
compensation cost related to restricted shares. That deferred cost will be recognized over a weighted-average
vesting period of 2.66 years. To the extent the actual forfeiture rate is different from the original estimate, actual
share-based compensation costs related to these awards may be different from the expectation.

The fair value of each option award was estimated on the date of grant using the Black-Scholes Method
valuation model. The volatility assumption was estimated based on implied volatility and historical volatility of the
Company’s share price applying the guidance provided by ASC subtopic 718-10 (“ASC 718-10”), Compensation-
Stock Compensation: Overall. The Company considered the comparable data in 2008 because the Company had
limited relevant historical information to support the expected volatility assumption as the Company has been a
public company only since August 2005. The Company begins to estimate the volatility assumption solely based on
its historical information since 2009. Assumptions about the expected term were based on the vesting and
contractual terms and employee demographics. The risk-free rate for periods within the contractual life of the
option is based on the U.S. Treasury yield curve in effect at the time of grant.

The following table presents the assumptions used to estimate the fair values of the share options granted in the

periods presented:

In addition, the Company recognizes share-based compensation expense net of an estimated forfeiture rate and
therefore only recognizes compensation cost for those shares expected to vest over the service period of the award.
The estimation of the forfeiture rate is based primarily upon historical experience of employee turnover. To the
extent the Company revises this estimate in the future, the share-based payments could be materially impacted in
the year of revision, as well as in following years. During the year ended December 31, 2010, the estimated
forfeiture rate decreased for the employee group primarily due to changes in historical employee turnover rates.

The exercise price of options granted during the years 2008, 2009, and 2010 equaled the market price of the
ordinary shares on the grant date. The weighted-average grant-date fair value of options granted during the years
2008, 2009, and 2010 was US$136.97, US$94.10, and US$279.69, respectively.

The total fair value of shares vested during the years ended December 31, 2008, 2009 and 2010 was

RMB37.57 million, RMB201.83 million, RMB237.71 million (US$36.02 million), respectively.

Total compensation cost recognized is as follows:

18. FAIR VALUE MEASUREMENT

ASC subtopic 820-10 (“ASC 820-10”), Fair Value Measurements and Disclosures: Overall, establishes a

three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in

active markets

Level 2 — Include other inputs that are directly or indirectly observable in the marketplace

Level 3 — Unobservable inputs which are supported by little or no market activity

ASC 820-10 describes three main approaches to measuring the fair value of assets and liabilities: (1) market
approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant

F-39

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

information generated from market transactions involving identical or comparable assets or liabilities. The income
approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is
based on the value indicated by current market expectations about those future amounts. The cost approach is based
on the amount that would currently be required to replace an asset.

Assets and liabilities measured at fair value on a recurring basis

In accordance with ASC 820-10, the Company measures cash equivalents and debt and equity securities,
including held-to-maturity, trading and available-for-sale securities, at fair value. Cash equivalents are valued using
quoted market prices. The Company’s held-to-maturity securities, including fixed-rate investments and adjustable-
rate investments, are stated at amortized cost with the fair value determined based on the discounted cash flow
model using the discount curve of market interest rates. The Company’s short-term available-for-sale securities
were recorded at fair value based on quoted market prices. The Company’s long-term available-for-sale securities
were initially recognized at the market price. The fair value on December 31, 2010 was determined by using the
income approach based on inputs that are unobservable in the market.

In May 2010, the Company acquired a long-term investment in 6DXchange Inc., which is classified as an
available-for-sale security. As there was no readily determinable fair value for the investment in 6DXchange Inc.,
the Company estimated its fair value as of December 31, 2010 using an income approach by considering cash flow
forecasts, discount rate, actual and projected operational performance and certain market data related to the
business of 6DXchange Inc. As of December 31, 2010, the fair value of long-term investments in available-for sale
securities approximates the cost of the investment of US$3.79 million. There has been no impairment charge of this
long-term available-for-sale security during the year ended December 31, 2010.

Assets and liabilities measured at fair value on a nonrecurring basis

The Company measures certain financial assets, including equity method investments and cost method
investments, at fair value on a nonrecurring basis only if an impairment charge were to be recognized. The
Company’s non-financial assets, such as intangible assets, goodwill and fixed assets, would be measured at fair
value only if they were determined to be other-than-temporarily impaired.

For the year ended December 31, 2010, the Company recognized an impairment loss on fixed assets, with a
charge to earnings, based on the fair value measurement (Level 3) on a non-recurring basis. The fair value was
determined using a discounted cash flow model under income approach based on future revenues and operating
costs, using internal projections. The impairment charge amounted to RMB12.40 million (US$1.88 million) for the
year ended December 31, 2010, which resulted from reduced use of certain capitalized internal-use software due to
changes in operations.

19. SUBSEQUENT EVENTS
