SELECTED FINANCIAL DATA

We prepared our consolidated financial statements included in this annual report in accordance with International Financial Reporting
Standards as issued by the International Accounting Standards Board (IFRS).

We present our financial statements in Mexican
pesos. This annual report contains translations of various peso amounts into U.S. dollars at specified rates solely for your convenience. You should not construe these translations as representations that the peso amounts actually represent the U.S.
dollar amounts or could be converted into U.S. dollars at the rate indicated. Unless otherwise indicated, we have translated U.S. dollar amounts from pesos at the exchange rate of Ps.13.0765 to U.S.$1.00, which was the rate reported by Banco de
México for December 31, 2013, as published in the Official Gazette of the Federation (Diario Oficial de la Federación, or Official Gazette).

In June 2011, we effected a two for one stock split. Unless otherwise noted, all share and per share data in this annual report have been
adjusted to reflect the stock split for all periods presented. The selected financial information should be read in conjunction with, and is qualified in its entirety by reference to, our audited consolidated financial statements. We have not
included earnings or dividends on a per American Depositary Share (ADS) basis. Each L Share ADS represents 20 L Shares and each A Share ADS represents 20 A Shares.

RISK FACTORS

Risks Relating to Our Operations

Competition in the telecommunications industry is intense and could adversely affect the revenues and profitability of our operations

Our businesses face substantial competition. We expect that competition will intensify in the future as a result of the entry of
new competitors, the development of new technologies, products and services and convergence. We also expect consolidation in the telecommunications industry, as companies respond to the need for cost reduction and additional spectrum. This trend may
result in larger competitors with greater financial, technical, promotional and other resources to compete with our businesses.

Among
other things, our competitors could:



| |  |  | provide increased handset subsidies;
| | - |  | ------------------------------------



| |  |  | offer higher commissions to retailers;
| | - |  | --------------------------------------



| |  |  | provide free airtime or other services (such as internet access);
| | - |  | -----------------------------------------------------------------



| |  |  | offer services at lower costs through double, triple and quadruple play packages or other pricing strategies;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | expand their networks faster; or
| | - |  | --------------------------------



| |  |  | develop and deploy improved technologies faster.
| | - |  | ------------------------------------------------

Competition can lead us to increase
advertising and promotional spending and to reduce prices for services and handsets. These developments may lead to smaller operating margins, greater choices for customers, possible consumer confusion and increasing movement of customers among
competitors, which may make it difficult for us to retain or add new customers. The cost of adding new customers may also continue to increase, reducing profitability even if customer growth continues.

Our ability to compete successfully will depend on our land coverage, the quality of our network and service, our rates, customer service,
effective marketing, our success in selling double, triple and quadruple play packages and our ability to anticipate and respond to various competitive factors affecting the telecommunications industry, including new services and technologies,
changes in consumer preferences, demographic trends, economic conditions and discount pricing strategies by competitors. If we are unable to respond to competition and compensate for declining prices by adding new customers, increasing usage and
offering new services, our revenues and profitability could decline.

New Legal Framework for the Regulation of Telecommunications
Services in Mexico

Mexico is currently developing a new legal framework for the regulation of telecommunications and broadcasting
services, based on a package of constitutional amendments enacted in June 2013. The new Federal Telecommunications Institute(Instituto Federal de Telecomunicaciones, or the IFT) issued a resolution in March 2014, determining that
our operating subsidiaries in Mexico are part of an economic interest group that is a preponderant economic agent in the Mexican telecommunications sector, and imposing certain asymmetric regulations on our Mexican fixed-line
and wireless businesses. A bill that proposes implementing legislation for the June 2013 constitutional amendments is currently under consideration in the Mexican Congress and is likely to be adopted in the near future. The long-term effects of the
IFT measures and the proposed legislation could be adverse to our interests in significant respects and could materially adversely affect our business and results of operations. We are contesting the IFTs preponderant economic agent
determination and the imposition of asymmetric regulations, but the existing measures are in effect while our challenge is pending, and failure to comply with the new legal framework may result in material fines as well as restrictions on our
operations and our ability to enter into new markets, such as broadcasting and Pay TV.

##### Table of Contents

Governmental or regulatory actions could adversely affect our operations

Our operations are subject to extensive government regulation and can be adversely affected by changes in law, regulation or regulatory policy.
The licensing, construction, operation, sale, resale and interconnection arrangements of telecommunications systems in Latin America and elsewhere are regulated to varying degrees by government or regulatory authorities. Any of these authorities
having jurisdiction over our businesses could adopt or change regulations or take other actions that could adversely affect our operations. In particular, the regulation of prices that operators may charge for their services could have a material
adverse effect by reducing our profit margins.

See Regulation under Item 4, Legal Proceedings under
Item 8 and Note 17 to our audited consolidated financial statements included in this annual report.

In addition, changes in
political administrations could lead to the adoption of policies concerning competition and taxation of communications services. For example, Mexico is developing a new legal framework that aims to promote competition and investment in the
telecommunications sector by imposing asymmetric regulation upon economic agents deemed preponderant. Furthermore, in the countries in which we operate outside of Mexico, we could face policies such as preferences for local over foreign
ownership of communications licenses and assets or for government over private ownership, which could make it more cumbersome or impossible for us to continue to develop our businesses. Restrictions such as those described above could result in our
incurring losses of revenues and require capital investments, all of which could materially adversely affect our businesses and results of operations.

Our failure to meet or maintain quality of service goals and standards could result in fines

The terms of the concessions under which our subsidiaries operate require them to meet certain service quality goals, including, for example,
minimum call completion rates, maximum busy circuits rates, operator availability and responsiveness to repair requests. Failure to meet service quality obligations in the past has resulted in the imposition of fines by regulatory entities. Our
ability to comply with these obligations in the future may be affected by factors beyond our control and, accordingly, we cannot assure that we will be able to comply with them.

Dominant carrier regulations could adversely affect our business by limiting our ability to pursue competitive and profitable strategies

Our regulators are authorized to impose specific requirements as to rates (including mobile termination rates), service quality
and information on operators that are determined to have substantial market power in a specific market. We cannot predict what steps regulatory authorities might take in response to determinations regarding substantial market power in the countries
in which we operate. However, adverse determinations against our subsidiaries could result in material fines, penalties or restrictions on our operations. We may also face additional regulatory restrictions and scrutiny as a result of our provision
of combined services.

We believe that if dominant carrier regulations are imposed on our business in the future, they will likely reduce
our flexibility to adopt competitive market policies and impose specific tariff requirements or other special regulations on us, such as additional requirements regarding disclosure of information or quality of service. For example, Mexico is
currently developing a new legal framework for the regulation of the telecommunications sector that imposes asymmetric measures on preponderant economic agents. Any such new regulation could have a material adverse effect on our operations.

We will have to acquire additional radio spectrum capacity and upgrade our existing networks in order to expand our customer base and
maintain the quality of our wireless services

Licensed radio spectrum is essential to our growth and the quality of our wireless
services, not only for our global system for mobile communications (GSM), universal mobile telecommunications systems (UMTS) and long term evolution (LTE) networks, but also for the deployment of new generation
networks to offer



6



---

##### Table of Contents

improved data and value-added services. We obtain most of our radio spectrum through auctions conducted by governments of the countries in which we operate. Participation in spectrum auctions in
most of these countries requires prior government authorization, and we may be subject to caps on our ability to acquire additional spectrum. Our inability to acquire additional radio spectrum capacity could affect our ability to compete
successfully because it could result in, among other things, a decrease in the quality of our network and service and in our ability to meet the demands of our customers.

In the event we are unable to acquire additional radio spectrum capacity, we can increase the density of our network by building more cell and
switch sites, but such measures are costly and would be subject to local restrictions and approvals, and they would not meet our needs as effectively.

In addition, the continual maintenance and upgrading of our wireless networks is critical to expanding our coverage, increasing our capacity
to absorb higher bandwidth usage and adapting to new technologies, as well as offering more specialized services to our customers.

Our concessions and licenses are for fixed terms, and conditions may be imposed on their renewal

Our concessions and licenses have specified terms, ranging typically from 5 to 20 years, and are generally subject to renewal upon payment of a
fee, but renewal is not assured. For example, we currently face upcoming renewals in both Chile and Colombia. The loss of, or failure to renew, any one concession could have a material adverse effect on our business and results of operations. Our
ability to renew concessions and the terms of renewal are subject to a number of factors beyond our control, including the prevalent regulatory and political environment at the time of renewal. Fees are typically established at the time of renewal.
As a condition for renewal, we may be required to agree to new and stricter terms and service requirements. If our concessions are not renewed, we are required to transfer the assets covered by the concession to the government, generally at fair
market value, although certain jurisdictions provide for other valuation methodologies.

In addition, the regulatory regimes and laws of
the jurisdictions in which we operate permit the government to revoke our concessions under certain circumstances. In Mexico, for example, the Federal Law on Telecommunications gives the government the right to expropriate our concessions or to take
over the management of our networks, facilities and personnel in cases of imminent danger to national security, internal peace or the national economy, natural disasters and public unrest.

We continue to look for acquisition opportunities, and any future acquisitions and related financing could have a material effect on our
business, results of operations and financial condition

We continue to look for investment opportunities in telecommunications and
related companies worldwide, including in markets where we are already present, and we often have several possible acquisitions under consideration. Any future acquisitions and related financing could have a material effect on our business, results
of operations and financial condition, but we cannot provide assurance that we will complete any of them. In addition, we may incur significant costs and expenses as we integrate these companies in our systems, controls and networks.

We are subject to significant litigation

Some of our subsidiaries are subject to significant litigation that, if determined adversely to our interests, may have a material adverse
effect on our business, results of operations, financial condition or prospects. Our significant litigation is described in Regulation under Item 4, Legal Proceedings under Item 8 and in Note 17 to our audited
consolidated financial statements included in this annual report.

We are contesting significant tax assessments

We and some of our subsidiaries have been notified of tax assessments for significant amounts by the tax authorities of the countries in
which we operate, especially in Mexico and Brazil. The tax assessments



7



---

##### Table of Contents

relate to, among other things, alleged improper deductions and underpayments. We are contesting these tax assessments in several administrative and legal proceedings, and our challenges are at
various stages. If determined adversely to us, these proceedings may have a material adverse effect on our business, results of operations, financial condition or prospects. In addition, in some jurisdictions challenges to tax assessments require
the posting of a bond or security for the contested amount, which may reduce our flexibility in operating our business. Our significant tax assessments are described in Note 17 to our audited consolidated financial statements included in this annual
report.

A system failure could cause delays or interruptions of service, which could have an adverse effect on our operations

We need to continue to provide our subscribers with a reliable service over our network. Some of the risks to our network and
infrastructure include the following:



| |  |  | physical damage to access lines and fixed networks;
| | - |  | ---------------------------------------------------



| |  |  | power surges or outages;
| | - |  | ------------------------



| |  |  | natural disasters;
| | - |  | ------------------



| |  |  | malicious actions, such as theft or misuse of customer data;
| | - |  | ------------------------------------------------------------



| |  |  | limitations on the use of our radio bases;
| | - |  | ------------------------------------------



| |  |  | software defects;
| | - |  | -----------------



| |  |  | human error; and
| | - |  | ----------------



| |  |  | disruptions beyond our control.
| | - |  | -------------------------------

In Brazil, for example, our satellite operations may be
affected if we experience a delay in launching new satellites to replace those currently in use when they reach the end of their operational lives. Such delay may occur because of, among other reasons, construction delays, unavailability of launch
vehicles and/or launch failures.

We have instituted measures to reduce these risks. However, there is no assurance that any measures we
implement will be effective in preventing system failures under all circumstances. System failures may cause interruptions in services or reduced capacity for our customers, either of which may have an adverse effect on our operations due to, for
example, increased expenses, potential legal liability, loss of existing and potential subscribers, reduced user traffic, decreased revenues and reputational harm.

Cyber attacks or other breaches of network or information technology security could have an adverse effect on our business

Cyber attacks or other breaches of network or information technology security may cause equipment failures or disruptions to our operations.
Our inability to operate our fixed line or wireless networks as a result of such events, even for a limited period of time, may result in significant expenses or loss of market share to other communications providers. In addition, the potential
liabilities associated with these events could exceed the insurance coverage we maintain. Cyber attacks, which include the use of malware, computer viruses and other means for disruption or unauthorized access on companies, have increased in
frequency, scope and potential harm in recent years. The preventive actions we take to reduce the risk of cyber incidents and protect our information technology and networks may be insufficient to repel a major cyber attack in the future. The costs
associated with a major cyber attack on us could include incentives offered to existing customers and business partners to retain their business, increased expenditures on cyber security measures, lost revenues from business interruption, litigation
and damage to our reputation. In addition, if we fail to prevent the theft of valuable information such as financial data and sensitive information about us, or if we fail to protect the privacy of customer and employee confidential data

against breaches of network or information technology security, it could result in damage to our reputation, which could adversely impact customer and investor confidence. Any of these
occurrences could result in a material adverse effect on our results of operations and financial condition.

If our churn rate
increases, our business could be negatively affected

The cost of acquiring a new subscriber is much higher than the cost of
maintaining an existing subscriber. Accordingly, subscriber deactivations, or churn, could have a material negative impact on our operating income, even if we are able to obtain one new subscriber for each lost subscriber. A substantial
majority of our subscribers are prepaid, and we do not have long-term contracts with them. Our weighted monthly average churn rate on a consolidated basis was 3.6% for the year ended December 31, 2012 and 3.6% for the year ended
December 31, 2013. If we experience an increase in our churn rate, our ability to achieve revenue growth could be materially impaired. In addition, a decline in general economic conditions could lead to an increase in churn, particularly among
our prepaid subscribers.

We rely on key suppliers and vendors to provide equipment that we need to operate our business

We rely upon various key suppliers and vendors, including Apple, Nokia, Sony (formerly known as Sony-Ericsson), Motorola, LG,
Samsung, Huawei, Alcatel-Lucent, Nokia Solutions and Networks (formerly known as Nokia Siemens Networks), Ericsson, ZTE and Blackberry to provide us with handsets, network equipment or services, which we need to expand and operate our business. If
these suppliers or vendors fail to provide equipment or service to us on a timely basis, we could experience disruptions, which could have an adverse effect on our revenues and results of operations. In addition, we might be unable to satisfy the
requirements contained in our concessions.

Our ability to pay dividends and repay debt depends on our subsidiaries ability to
transfer income and dividends to us

We are a holding company with no significant assets other than the shares of our subsidiaries
and our holdings of cash and cash equivalents. Our ability to pay dividends and repay debt depends on the continued transfer to us of dividends and other income from our subsidiaries. The ability of our subsidiaries to pay dividends and make other
transfers to us may be limited by various regulatory, contractual and legal constraints that affect them.

We may fail to realize

opportunities, revenue benefits, cost savings and other benefits we anticipated to result from our acquisitions and significant investments may not be achieved as expected, or may be delayed. For example, we may be unable to fully implement our
business plans and strategies for the combined businesses due to regulatory limitations, and we may face regulatory restrictions in our provision of combined services in some of the countries in which we operate. To the extent that we incur higher
integration costs or achieve lower revenue benefits or fewer cost savings than expected, or if we are required to recognize impairments of acquired assets, investments or goodwill, our results of operations and financial condition may suffer.

Risks Relating to the Telecommunications Industry Generally

Changes in the telecommunications industry could affect our future financial performance

The telecommunications industry continues to experience significant changes as new technologies are developed that offer subscribers an array
of choices for their communications needs. These changes include, among others, regulatory changes, evolving industry standards, ongoing improvements in the capacity and quality of digital technology, shorter development cycles for new products, and
changes in end-user needs and

preferences. In Mexico and in the other countries in which we conduct business, there is uncertainty as to the pace and extent of growth in subscriber demand, and as to the extent to which prices
for airtime, broadband access, Pay TV and fixed line rental may continue to decline. Our ability to compete in the delivery of high-quality internet and broadband services is particularly important, given the increasing contribution of revenues from
data services to our overall growth. If we are unable to meet future advances in competing technologies on a timely basis or at an acceptable cost, we could lose subscribers to our competitors. In general, the development of new services in our
industry requires us to anticipate and respond to the varied and continually changing demands of our subscribers. It also requires significant capital expenditure, including investment in the continual maintenance and upgrading of our networks, in
order to expand coverage, increase our capacity to absorb higher bandwidth usage and adapt to new technologies. We may not be able to accurately predict technological trends or the success of new services in the market. In addition, there could be
legal or regulatory restraints to our introduction of new services. If these services fail to gain acceptance in the marketplace, or if costs associated with implementation and completion of the introduction of these services materially increase,
our ability to retain and attract subscribers could be adversely affected. This is true across many of the services we provide, including wireless and cable technology.

The intellectual property rights utilized by us, our suppliers or service providers may infringe on intellectual property rights owned
by others

Some of our products and services use intellectual property that we own or license from others. We also provide content
services we receive from content producers and distributors, such as ring tones, text games, video games, video, including TV programs and movies, wallpapers or screensavers, and we outsource services to service providers, including billing and
customer care functions, that incorporate or utilize intellectual property. We and some of our suppliers, content distributors and service providers have received, and may receive in the future, assertions and claims from third parties that the
content, products or software utilized by us or our suppliers, content producers and distributors and service providers infringe on the patents or other intellectual property rights of these third parties. These claims could require us or an
infringing supplier, content distributor or service provider to cease engaging in certain activities, including selling, offering and providing the relevant products and services. Such claims and assertions also could subject us to costly litigation
and significant liabilities for damages or royalty payments, or require us to cease certain activities or to cease selling certain products and services.

Concerns about health risks relating to the use of wireless handsets and base stations may adversely affect our business

Portable communications devices have been alleged to pose health risks, including cancer, due to radio frequency emissions. Lawsuits have been
filed in the United States against certain participants in the wireless industry alleging various adverse health consequences as a result of wireless phone usage, and our subsidiaries may be subject to similar litigation in the future. Research and
studies are ongoing, and there can be no assurance that further research and studies will not demonstrate a link between radio frequency emissions and health concerns. Any negative findings in these studies could adversely affect the use of wireless
technology and, as a result, our future financial performance.

Developments in the telecommunications sector have resulted, and may
result, in substantial write-downs of the carrying value of certain of our assets

We review on an annual basis, or more frequently
where the circumstances require, the carrying value of each of our assets, subsidiaries, and investments in associates to assess whether those carrying values can be supported by the future discounted cash flows expected to be derived from such
assets. Whenever we consider that due to changes in the economic, regulatory, business or political environment, our goodwill, investments in associates, intangible assets or fixed assets may be impaired, we consider the necessity of performing
certain valuation tests, which may result in impairment charges. The recognition of impairments of tangible, intangible and financial assets could adversely affect our results of operations. See Impairment of Long-Lived Assets under
Item 5.

Risks Relating to Our Controlling Shareholders, Capital Structure and Transactions with Affiliates

Members of one family may be deemed to control us

Based on reports of beneficial ownership of our shares filed with the SEC, Carlos Slim Helú, together with his sons and daughters
(together, the Slim Family), including his two sons who are co-chairs of our Board of Directors, Patrick Slim Domit and Carlos Slim Domit, may be deemed to control us. The Slim Family may be able to elect a majority of the members of our
Board of Directors and to determine the outcome of other actions requiring a vote of our shareholders, except in very limited cases that require a vote of the holders of L Shares. The interests of the Slim Family may diverge from the interests of
our other investors.

We have significant transactions with affiliates

We engage in different transactions with certain subsidiaries of Grupo Carso, S.A.B. de C.V. and Grupo Financiero Inbursa, S.A.B. de C.V.,
which may be deemed for certain purposes to be under common control with América Móvil, as well as with subsidiaries of our shareholder AT&T, Inc. Many of these transactions occur in the ordinary course of business. Transactions
with affiliates may create the potential for conflicts of interest.

We also make investments together with related parties, sell our
investments to related parties and buy investments from related parties. For more information about our transactions with affiliates see Related Party Transactions under Item 7.

Our bylaws restrict transfers of shares in some circumstances

Our bylaws provide that any acquisition or transfer of more than 10% of our capital stock by any person or group of persons acting together
requires the approval of our Board of Directors. You may not acquire or transfer more than 10% of our capital stock without the approval of our Board of Directors.

The protections afforded to minority shareholders in Mexico are different from those in the United States

Under Mexican law, the protections afforded to minority shareholders are different from those in the United States. In particular, the law
concerning fiduciary duties of directors is not as fully developed as in other jurisdictions, there is no procedure for class actions, and there are different procedural requirements for bringing shareholder lawsuits. As a result, in practice it may
be more difficult for minority shareholders of América Móvil to enforce their rights against us or our directors or controlling shareholder than it would be for shareholders of a company incorporated in another jurisdiction, such as
the United States.

Holders of L Shares and L Share ADSs have limited voting rights

Our bylaws provide that holders of L Shares are not permitted to vote except on such limited matters as, among others, the
transformation or merger of América Móvil or the cancellation of registration of the L Shares with the National Securities Registry (Registro Nacional de Valores or RNV) maintained by CNBV or any stock exchange
on which they are listed. If you hold L Shares or L Share ADSs, you will not be able to vote on most matters, including the declaration of dividends that are subject to a shareholder vote in accordance with our bylaws.

Holders of ADSs are not entitled to attend shareholders meetings, and they may only vote through the depositary

Under our bylaws, a shareholder is required to deposit its shares with a custodian in order to attend a shareholders meeting. A holder of
ADSs will not be able to meet this requirement, and accordingly is not entitled to attend shareholders meetings. A holder of ADSs is entitled to instruct the depositary as to how to vote the shares represented by ADSs, in accordance with
procedures provided for in the deposit agreements, but a holder of ADSs will not be able to vote its shares directly at a shareholders meeting or to appoint a proxy to do so.

##### Table of Contents

Mexican law and our bylaws restrict the ability of non-Mexican shareholders to invoke the
protection of their governments with respect to their rights as shareholders

As required by Mexican law, our bylaws provide that
non-Mexican shareholders shall be considered as Mexicans with respect to their ownership interests in América Móvil and shall be deemed to have agreed not to invoke the protection of their governments under certain circumstances. Under
this provision, a non-Mexican shareholder is deemed to have agreed not to invoke the protection of his own government by asking such government to interpose a diplomatic claim against the Mexican government with respect to the shareholders
rights as a shareholder, but is not deemed to have waived any other rights it may have, including any rights under the U.S. securities laws, with respect to its investment in América Móvil. If you invoke such governmental protection in
violation of this provision, your shares could be forfeited to the Mexican government.

Our bylaws may only be enforced in Mexico

Our bylaws provide that legal actions relating to the execution, interpretation or performance of the bylaws may be brought only
in Mexican courts. As a result, it may be difficult for non-Mexican shareholders to enforce their shareholder rights pursuant to the bylaws.

It may be difficult to enforce civil liabilities against us or our directors, officers and controlling persons

América Móvil is a sociedad anónima bursátil de capital variable organized under the laws of Mexico,
with its principal place of business (domicilio social) in Mexico City, and most of our directors, officers and controlling persons reside outside the United States. In addition, all or a substantial portion of our assets and their assets are
located outside of the United States. As a result, it may be difficult for investors to effect service of process within the United States on such persons or to enforce judgments against them, including in any action based on civil liabilities under
the U.S. federal securities laws. There is doubt as to the enforceability against such persons in Mexico, whether in original actions or in actions to enforce judgments of U.S. courts, of liabilities based solely on the U.S. federal securities
laws.

You may not be entitled to participate in future preemptive rights offerings

Under Mexican law, if we issue new shares for cash as part of certain capital increases, we must grant our shareholders the right to purchase a
sufficient number of shares to maintain their existing ownership percentage in América Móvil. Rights to purchase shares in these circumstances are known as preemptive rights. Our shareholders do not have preemptive rights in certain
circumstances such as mergers, convertible debentures, public offers and placement of repurchased shares. We may not be legally permitted to allow holders of ADSs or holders of L Shares or A Shares in the United States to exercise any
preemptive rights in any future capital increase unless we file a registration statement with the SEC with respect to that future issuance of shares. At the time of any future capital increase, we will evaluate the costs and potential liabilities
associated with filing a registration statement with the SEC and any other factors that we consider important to determine whether we will file such a registration statement.

We cannot assure you that we will file a registration statement with the SEC to allow holders of ADSs or U.S. holders of L Shares or
A Shares to participate in a preemptive rights offering. As a result, the equity interest of such holders in América Móvil may be diluted proportionately. In addition, under current Mexican law, it is not practicable for the
depositary to sell preemptive rights and distribute the proceeds from such sales to ADS holders.

Risks Relating to Developments in Mexico and Other
Countries

Latin American and Caribbean economic, political and social conditions may adversely affect our business

Our financial performance may be significantly affected by general economic, political and social conditions in the markets where we operate,
particularly in Mexico, Brazil, Colombia and Central America. Many countries in



12



---

##### Table of Contents

Latin America and the Caribbean, including Mexico, Brazil and Argentina have suffered significant economic, political and social crises in the past, and these events may occur again in the
future. We cannot predict whether changes in political administrations will result in changes in governmental policy and whether such changes will affect our business. Factors related to economic, political and social conditions that could affect
our performance include:



| |  |  | significant governmental influence over local economies;
| | - |  | --------------------------------------------------------



| |  |  | substantial fluctuations in economic growth;
| | - |  | --------------------------------------------



| |  |  | high levels of inflation;
| | - |  | -------------------------



| |  |  | changes in currency values;
| | - |  | ---------------------------



| |  |  | exchange controls or restrictions on expatriation of earnings;
| | - |  | --------------------------------------------------------------



| |  |  | high domestic interest rates;
| | - |  | -----------------------------



| |  |  | price controls;
| | - |  | ---------------



| |  |  | changes in governmental economic or tax policies;
| | - |  | -------------------------------------------------



| |  |  | imposition of trade barriers;
| | - |  | -----------------------------



| |  |  | unexpected changes in regulation; and
| | - |  | -------------------------------------



| |  |  | overall political, social and economic instability.
| | - |  | ---------------------------------------------------

Adverse economic, political and social
conditions in Latin America may inhibit demand for telecommunication services and create uncertainty regarding our operating environment or may affect our ability to renew our licenses and concessions, to maintain or increase our market share or
profitability and may have an adverse impact on future acquisition efforts, which could have a material adverse effect on our company.

Our business may be especially affected by conditions in Mexico and Brazil, our two principal markets. For example, our results of operations
were adversely affected by weak economic conditions in Mexico and Brazil in 2013, and may be so affected again in 2014.

Changes in
exchange rates could adversely affect our financial condition and results of operations

We are affected by fluctuations in the
value of the currencies in which we conduct operations compared to the currencies in which our indebtedness is denominated. Such changes result in exchange losses or gains on our net indebtedness and accounts payable. In 2012, changes in currency
exchange rates led us to report net foreign exchange gains of Ps.7,395 million. In 2013, we reported net foreign exchange losses of Ps.19.6 billion. In addition, currency fluctuations between the Mexican peso and the currencies of our non-Mexican
subsidiaries affect our results as reported in Mexican pesos. Currency fluctuations are expected to continue to affect our financial income and expense.

Major devaluation or depreciation of the currencies in which we conduct operations could cause governments to impose exchange controls
that would interfere with or limit our ability to transfer funds between us and our subsidiaries.

Major devaluation or
depreciation of any such currencies may also result in disruption of the international foreign exchange markets and may limit our ability to transfer or to convert such currencies into U.S. dollars and other currencies for the purpose of making
timely payments of interest and principal on our indebtedness. For example, although the Mexican government does not currently restrict, and for many years has not restricted, the right or ability of Mexican or foreign persons or entities to convert
pesos into U.S. dollars or to transfer other currencies out of Mexico, it could, however, institute restrictive exchange rate policies in the future. Similarly, the Brazilian government may impose temporary restrictions on the conversion of
Brazilian reais into foreign



13

##### Table of Contents

currencies and on the remittance to foreign investors of proceeds from investments in Brazil whenever there is a serious imbalance in Brazils balance of payments or a reason to foresee a
serious imbalance. The Argentine peso has experienced significant devaluation over the past several years and the government has adopted various rules and regulations since late 2011 that established new restrictive controls on capital flows into
the country. These enhanced exchange controls have practically closed the foreign exchange market to retail transactions, and the Argentine peso/U.S. dollar exchange rate in the unofficial market substantially differs from the official foreign
exchange rate. The Argentine government could impose further exchange controls or restrictions on the movement of capital and take other measures in the future in response to capital flight or a significant depreciation of the Argentine peso.

Developments in other countries may affect the market price of our securities and adversely affect our ability to raise additional
financing

The market value of securities of Mexican companies is, to varying degrees, affected by economic and market conditions
in other countries, including the United States, the European Union and emerging market countries. Although economic conditions in such countries may differ significantly from economic conditions in Mexico, investors reactions to developments
in any of these other countries may have an adverse effect on the market value of securities of Mexican issuers. Crises in the United States, the European Union and emerging market countries may diminish investor interest in securities of Mexican
issuers. This could materially and adversely affect the market price of our securities, and could also make it more difficult for us to access the capital markets and finance our operations in the future on acceptable terms or at all.

History and Corporate Information

América Móvil, S.A.B. de C.V. is a sociedad anónima bursátil de capital variable organized under the laws of
Mexico. We were established in September 2000 when Telmex, a fixed-line Mexican telecommunications operator, privatized in 1990 and spun off to us its mobile operations in Mexico and other countries. We have made significant acquisitions throughout
Latin America and the Caribbean, and we have also expanded our businesses organically. During 2010, we acquired control of Telmex and Telmex Internacional, S.A.B. de C.V. (currently, Telmex Internacional, S.A. de C.V., or Telmex
Internacional) in a series of public tender offers. We continue to look for other investment opportunities in telecommunication companies worldwide, including in markets where we are already present, and we often have several possible
acquisitions under consideration.

Our principal executive offices are located at Lago Zurich 245, Plaza Carso, Edificio Telcel, Colonia
Ampliación Granada, Delegación Miguel Hidalgo, 11529, México D.F., México. Our telephone number at this location is (5255) 2581-4449.

Recent Developments

Mexican
Telecommunications Reforms

In late 2012, Mexico began a process of significantly changing the legal framework for the regulation
of telecommunications and broadcasting services. These reforms are aimed at enhancing and promoting investment in the telecommunications and broadcasting sectors in Mexico, in order to increase penetration, promote universal coverage, reduce prices
and provide the whole population with access to quality services and content.

##### Table of Contents

The first legal step in the reforms was a package of constitutional amendments that became
effective in June 2013. Among other things, the constitutional amendments established a new Federal Telecommunications Institute (Instituto Federal de Telecomunicaciones, or the IFT), established specialized courts for
telecommunications and broadcasting matters, and identified criteria for declaring a preponderant economic agent in each of the telecommunications and broadcasting sectors and certain asymmetric measures that may be imposed to protect
competition and consumers. The ultimate effects of the amendments on us and our competitors will depend on implementing legislation and regulatory actions.

On March 7, 2014, the IFT issued a resolution declaring that we and our operating subsidiaries Telcel, Telmex and Telnor, along with
certain other companies that have common shareholders with us, comprise an economic interest group that is a preponderant economic agent in the telecommunications market. In the same resolution, the IFT also imposed certain
specific asymmetric measures on us and our operating subsidiaries, many of which could have material and adverse effects on our operations in Mexico and our financial results. The IFTs preponderant economic agent determination and the
asymmetric measures it imposed on us are summarized under RegulationMexicoAsymmetric Regulation of the Preponderant Economic Agent.

We have filed, in the specialized telecommunications courts created by the constitutional amendments, a challenge (juicio de amparo) to
the IFTs preponderant economic agent determination and the imposition of asymmetric measures. We are unable to predict the likelihood of our success in that challenge, or the timing of any final result, and the courts will not suspend the
IFTs asymmetric measures while our challenge is pending.

On March 24, 2014, the Mexican President submitted a bill to Congress
proposing implementing legislation for the June 2013 constitutional amendments. When enacted, the legislation will establish the new Federal Law on Telecommunications and Broadcasting (Ley Federal de Telecomunicaciones y
Radiodifusión). The currently available public version of the bill would phase out long-distance charges for fixed-line and mobile services in Mexico, in the case of fixed-line services over a one-year period, and in the case of mobile
services over a period determined by the IFT. In addition, the bill proposes new measures that would apply to an entity determined to be the preponderant economic agent in the telecommunications sector, including:



| |  |  | setting fixed and mobile interconnection rates at zero until the IFT determines there is effective competition in the telecommunications sector;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | requiring all rates to be approved by the IFT before going into effect, and imposing specific rate requirements; and
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | conditioning our ability to provide broadcasting or Pay TV services on, among other things, two years of compliance with the IFTs asymmetric measures and the new federal law, and the payment of any new concession
fees.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We expect that the implementing legislation will be adopted in 2014, but we cannot predict the content of the final legislation.
Additional measures proposed by the bill are summarized under RegulationMexico.

Telekom Austria

On April 23, 2014, we announced that we had entered into a shareholders agreement (the TKA Shareholders Agreement) with
Telekom Austrias largest shareholder, Österreichische Industrieholding AG (or OIAG), an entity controlled by the Republic of Austria. Together, we and OIAG own more than 50% of the voting shares of Telekom Austria. The TKA
Shareholders Agreement has a term of ten years, subject to termination if, among other things, either partys participation in Telekom Austria falls below 10%. The effectiveness of the TKA Shareholders Agreement and the launching of
TKA Offer (as defined below) are subject to certain regulatory approvals in Austria, and certain merger control authorizations in Austria and in the other Central and Eastern European countries in which Telekom Austria currently operates.

##### Table of Contents

The TKA Shareholders Agreement provides for nominations to Telekom Austrias
supervisory board and management board (together, the TKA Boards) and for the coordinated exercise of voting on the TKA Boards and at shareholders meetings, subject, in both cases, to certain specific veto rights in favor of OIAG
that are summarized below. Under these provisions, we will have the right to appoint the majority of the members of each of the TKA Boards. Resolutions by both of the TKA Boards are adopted by a simple majority.

As long as OIAG holds more than 25% of Telekom Austrias share capital, OIAG will have veto rights with respect to certain matters,
including capital increases that would result in OIAGs shareholding falling to 25% or below, appointment of Telekom Austrias statutory auditors, relocation of Telekom Austrias corporate headquarters outside of Austria, related
party transactions, sale of core businesses and amendments to the corporate name of Telekom Austria. Certain of these veto rights will remain in effect even if OIAGs shareholding falls to 25% or below.

As a result of signing the TKA Shareholders Agreement, we are required by Austrian law to offer to purchase all of the outstanding
shares of Telekom Austria not held by us, OIAG or Telekom Austria (the TKA Offer). We expect to launch the TKA Offer during May or June 2014 at a price of 7.15 per share, subject to obtaining regulatory approvals. The total
purchase price for us, if all the outstanding shares subject to the TKA Offer are tendered, would be approximately 1.4 billion.

Also under the terms of the TKA Shareholders Agreement, we and OIAG have agreed to vote in favor of a capital increase for Telekom
Austria of 1.0 billion. We have also agreed to participate in the capital increase, pro-rata to our then current participation in Telekom Austria, and OIAG has agreed to participate as necessary in order for it to maintain ownership of
more than 25% of Telekom Austria. The capital increase is subject to the closing of the TKA Offer.

AMX-1 Submarine Cable System

In July 2014, we expect to begin commercial operation of América Móvil 1 (the AMX-1 System), a 17,500 km
submarine cable system initially deployed with 40 Gigabit per second (40G) transmission and specifically designed for 100 Gigabit per second (100G) transmission. The cable runs from the United States to Central America and Brazil and
enables us to provide international connectivity to all our subsidiaries in those areas. The AMX-1 System connects seven countries via eleven landing points. The higher transmission speeds we will be able to achieve as a result of the new system
should substantially improve our customers communications experiences, providing opportunities for creation and innovation.

Acquisition of Start Wireless Group

On January 16, 2014, our subsidiary TracFone acquired substantially all of the assets of Start Wireless Group, Inc. (Start
Wireless), which operates under the Page Plus brand. Start Wireless is a mobile virtual network operator in the United States, and provides services to approximately 1.4 million customers and offers, among other services, prepaid voice
plans, messaging and data.

Services and Products

Voice Services and Products

Telcel offers wireless voice and data services under a variety of service plans to meet the needs of different user segments. The plans are
either postpaid, where the customer is billed monthly for the previous month, or prepaid, where the customer pays in advance for a specified volume of use over a specified period. Although prepaid customers typically generate
lower levels of usage and are often unwilling to make a fixed financial commitment or do not have the credit profile to purchase postpaid plans, we believe the prepaid market represents a large and growing market in Mexico because, compared to the
average postpaid plan, prepaid plans involve higher average per minute airtime charges, lower customer acquisition costs and billing expenses, and no payment risk.

Rates for postpaid plans have not increased since April 1999 and rates for prepaid plans have not increased since 2002. Rates for both types
of plans are affected by the Mexican economic and regulatory environment. In addition, in recent periods Telcel has offered certain discounts and promotions that reduce the effective rates that its postpaid and prepaid customers pay.

Telcel offers international roaming services to its subscribers through the networks of cellular service providers with which Telcel has
entered into international roaming agreements around the world. In Mexico, Telcel also provides GSM and 3G roaming services to customers of Telcels international roaming partners.

In connection with the provision of its voice services, Telcel earns mobile termination revenues from calls to any of its subscribers that
originate with another service provider. Telcel charges the service provider from



20

##### Table of Contents

whose network the call originates a mobile termination charge for the time Telcels network is used in connection with the call. Similarly, Telcel must pay mobile termination fees in respect
of calls made by its subscribers to customers of other service providers. There has been extensive controversy, and legal and administrative proceedings, concerning the terms of these interconnection agreements in Mexico, and in the future, Telcel
may not be able to charge other service providers for mobile termination charges. See Recent Developments, RegulationMexico and RegulationMexicoMexican Regulatory ProceedingsMobile Termination
Rates under this Item 4 and Note 17 to our audited consolidated financial statements included in this annual report.

Value-Added Services

Telcel offers value-added services, including data, messaging, mobile entertainment and enterprise mobility services.

Data Services

Through its GSM/EDGE, 3G and 4G LTE networks, Telcel offers mobile internet connectivity for feature phones, smartphones, tablets and laptops,
including data transmission, e-mail services, instant messaging, content streaming, interactive applications and other internet services. Telcel also offers data services through roaming service agreements.

Handsets and Accessories

Telcel offers a variety of products as complements to its wireless services, including handsets, smartphones, broadband cards, tablets and

Marketing

Telcel develops
customer and brand awareness through its marketing and promotion efforts and high-quality customer care. Telcel builds upon the strength of its well-recognized brand name to increase consumer awareness and customer loyalty, employing continuous
advertising efforts through print, radio, television, digital media, sponsorship of sports events and other outdoor advertising campaigns. Telcel promotes social responsibility through programs such as its alliances with the World Wildlife Fund and
the (RED) campaign. In addition, Telcel has a loyalty rewards program, Círculo Azul, that offers postpaid customers points that can be redeemed for handsets and other goods or services provided by third parties.

In 2013, our marketing efforts were mainly focused on highlighting that we have one of the best 3G networks in the world, while also
promoting our 4G LTE network in the main cities of Mexico.

Sales and Distribution

Telcel markets its wireless services and products primarily through exclusive distributors located throughout Mexico, who sell Telcels
services and products, including handsets, postpaid plans and prepaid cards, and receive commissions through approximately 21,533 points of sale. In addition, Telcels company-owned retail



21

##### Table of Contents

stores offer one-stop shopping for a variety of wireless services and products. Walk-in customers can subscribe for postpaid plans, purchase prepaid cards and purchase handsets and accessories.
As of December 31, 2013, Telcel owned and operated 346 customer sales and service centers throughout Mexico and will continue to open new sales and service centers as necessary in order to offer its products directly to subscribers in more
effective ways. In addition, Telcel has a dedicated corporate sales group to service the needs of its large corporate and other high-usage customers. In the year ended December 31, 2013, approximately 30% of Telcels sales of handsets were
generated by cellular distributors, 22% from sales in company-owned stores and 48% from direct sales to corporate accounts.

Billing and Collection

Telcel bills its postpaid customers through monthly invoices, which detail itemized charges. Customers may pay their bills through
pre-authorized debit or credit charges, in person at banks and at Telcels and other designated retail stores and electronically through the internet websites of Telcel and of banks.

If a postpaid customers payment is overdue, service may be suspended temporarily until full payment for all outstanding charges is
received. If the subscribers payment is more than 60 days past due, service may be discontinued permanently. Accounts that are more than 90 days past due are considered doubtful accounts.

A prepaid customer who purchases airtime credit has between 7 to 60 days, depending on the amount purchased, to use the airtime. After 30 or
60 days, the customer can no longer use that airtime for outgoing calls unless the customer purchases additional airtime credit.

Customer Service

Telcel places a high priority on providing its customers with quality customer care and support, with approximately 65.6% of
Telcels employees dedicated to customer service. Customers may call a toll-free telephone number, go to one of the customer sales and service centers located throughout Mexico or access Telcels website to make inquiries.

Our Networks and Technology

Telcels wireless networks, which cover approximately 94.5% of the Mexican population, use digital technologies in the 850 MHz frequency
spectrum, 1900 MHz frequency spectrum and the 1.7/2.1 GHz frequency spectrum. As of December 31, 2013, Telcel has networks using:



| |  |  | GSM technology in the 1900 and 850 MHz frequency spectrums;
| | - |  | -----------------------------------------------------------



| |  |  | enhanced data rates for GSM evolution (EDGE) technologies in the 1900 and 850 MHz frequency spectrum;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | 3G UMTS/HSPA technologies in the 850 and 1900 MHz frequency spectrum; and
| | - |  | -------------------------------------------------------------------------



| |  |  | 4G LTE technology in the 1.7/2.1 GHz frequency spectrum.
| | - |  | --------------------------------------------------------

GSM/EDGE network

Currently, Telcels GSM network offers service in all nine regions in Mexico, having built and installed a GSM network in the 1900 MHz
spectrum in those regions. In addition, Telcel has continued with the expansion of its GSM network by using the 850 MHz and 1900 MHz spectrum since 2006. As of December 31, 2013, Telcels GSM subscriber base represented approximately 67.2%
of Telcels total subscribers.

In addition, Telcel upgraded the GSM network with EDGE technology in 2005. It has implemented EDGE
technology in all localities with GSM coverage (approximately 202,000 localities), including all the major cities and roads in Mexico.

##### Table of Contents

3G network

Telcel operates a UMTS 3G network in Mexico using the existing 850 MHz spectrum using HSPA, a mobile telephony communications protocol that
allows networks based on UMTS to have higher data transfer speeds and capacity. In addition, Telcel continues to expand its 3G network by using the 1900 MHz spectrum band. As of December 31, 2013, Telcels UMTS/HSPA network covered
approximately 132,672 localities, including all of Mexicos principal cities. Telcel plans to continue expanding its 3G coverage in Mexico throughout 2014 to urban as well as rural areas. As of December 31, 2013, Telcels UMTS/HSPA
subscriber base represented approximately 31.4% of Telcels total subscribers. We expect to improve our network coverage in cities and areas with high data usage through the ongoing deployment of HSPA+ protocol.

4G network

In
2010, Telcel obtained additional spectrum in the 1.7/2.1 GHz spectrum for each of the nine regions of Mexico. In November 2012, Telcel began offering 4G services using a LTE technology based network in Mexicos nine major cities and expanded
its coverage to other large and medium cities through 2013. Telcel plans to continue expanding its coverage through 2014. LTE allows us to offer higher bitrates in mobile data services and is the leading 4G technology across the globe. As of
December 31, 2013, Telcels LTE subscriber base represented approximately 1.4% of Telcels total subscribers.

Competition

Telcel faces competition from other wireless providers using the 850 MHz spectrum and from providers with Personal Communications Service
(PCS) licenses that provide wireless service on the 1900 MHz spectrum. Telcels principal competitors in Mexico are Iusacell S.A. de C.V. and Telefónica S.A. Telcel also competes with Comunicaciones Nextel de México,
S.A. de C.V. in certain regions.

The effects of competition on Telcel depend, in part, on the business strategies of its competitors, on
regulatory developments and on the general economic and business climate in Mexico, including demand growth, interest rates, inflation and exchange rates. The effects could include loss of market share and pressure to reduce rates. See
RegulationMexico under this Item 4.

Voice Services and Products

Telmex offers a variety of fixed-line voice services and products, including local-service, domestic and international long-distance service
and public telephony services, under a variety of plans to meet the needs of different market segments.

Telmex charges for fixed-line
local telephone service include (a) installation charges, (b) monthly line-rental charges, (c) local-service calls, (d) digital services and (e) charges for other services, such as the transfer and reconnection of a line to
another address. Residential customers pay a fixed charge per local call in excess of a monthly allowance of 100 local calls, and commercial customers pay for every local call. The concession Telmex holds to operate a public network for basic
telephone services allows but does not require Telmex to base its charges on the duration of each call. Telmex does not currently charge by duration of calls in any region, except in the case of prepaid services.

Telmexs rates for domestic long-distance service are based on call duration and type of service (direct-dial or operator-assisted) and
apply once customers exceed the number of minutes included in their service packages. Under the 2014 telecommunications legislation, Telmex must phase out domestic long-distance charges over a three-year period ending in 2017.

Charges for international long-distance calls are based on call duration, type of service (direct-dial or operator-assisted) and the
destination of the call. These charges apply once customers exceed the number of

minutes included in their plan. Customers can choose from a variety of discount rate plans. Telmex has not increased its rates since 2001 for local telephone service and since 1999 for domestic
long-distance service and international long-distance calls, continuing its trend of offering lower rates in real terms every year. In addition, Telmex provides interconnection services pursuant to which (a) long-distance, local and
mobile-phone carriers operating in Mexico establish points of interconnection between their networks and Telmexs network and (b) Telmex carries calls between the points of interconnection and its customers. When a customer of another
carrier calls a local-service customer of Telmex, Telmex completes the call by carrying the call from the point of interconnection to the particular customer, and when a local-service customer of Telmex who has preselected a competing long-distance
carrier makes a long-distance call, Telmex carries the call from the customer to the point of interconnection with that other long-distance carriers network. As a result of Mexicos bill and keep system, under which local
carriers and cable television providers do not pay interconnection fees to other local carriers, Telmex does not receive an interconnection fee from these calls.

Data Services and Products

Telmexs data service business is comprised of internet access service and corporate network services. Telmexs broadband service,
which it provides under the Infinitum brand, allows its customers to use its high-capacity connectivity services with applications such as video-conferencing, file transfer and e-mail. Infinitum operates over
Asymmetric Digital Subscriber Line technology.

Corporate network services consist of voice, video and data-transmission between two or
more end points using private circuits. Telmexs principal products for corporate networks are Ladaenlaces (Ladalinks) and multi-service virtual private networks (VPNs), which allows Telmex to
provide different levels of service applications. Telmex also provides specialized assistance and technical support for these applications, as well as network-outsourcing services that include maintenance, support and integration of communication
networks and information systems.

Other Services and Products

Consistent with Telmexs strategy of increasing the value of its fixed-line service, it has focused on customers needs, and offers
packages of telecommunications services that include internet access and a customized mix of local calls, minutes for domestic calls, international long-distance calls and calls to wireless phones.

In addition, Telmex provides various telecommunications and telecommunications-related products and services that include sales of computers,
telecommunications equipment and accessories, public phone services and billing and collection services to third parties. Telmex offers billing and collection services through its phone bills to other companies.

Telmex currently provides billing and collection services to companies such as Medicall Home, Socio Águila, Teletón,
Telecomunicaciones de México and Dish México S. de R.L. de C.V. (Dish México). In November 2008, Telmex entered into several agreements with Dish México and its affiliates, which operate a DTH Pay TV system in
Mexico, pursuant to which Telmex is currently providing customary services, including billing and collection, among others.

Sales and Distribution

Telmex uses its network of Telmex stores (Tiendas Telmex) to offer its products and services throughout Mexico. In
addition to functioning as customer-service centers, Telmexs stores offer a wide range of computer and telecommunications equipment and accessories, which may be purchased outright or through installment payment plans.

Telmex bills its customers through monthly invoices, which detail itemized charges. Customers may pay their bills through pre-authorized debit

Our Networks and Technology

Telmexs local and long-distance fiber optic network consists of approximately 181,300 kilometers that connect all major cities in Mexico.
In addition, Telmexs local and long-distance fiber optic network connects Mexico, through submarine cables, with multiple other countries.

Competition

Telmex faces competition
from other holders of long-distance and local-service licenses, Pay TV operators that provide telephone and internet service and wireless telecommunications providers. Telmexs main competitors in Mexico are Alestra S. de R.L. de C.V., Axtel

Brasil prepaid customer who purchases a card has between 10 and 300 days from the date of activation of the card to use the airtime, depending on the amount added. After such time, the customer can no longer use that airtime for outgoing calls
unless the customer activates a new card.

Fixed-line Operations

Embratel directly bills a portion of its customers for their fixed-line telecommunications and related services, including collect-calling and
standard voice services. However, due to the risk of bad debts resulting from direct billing, Embratel has taken a number of measures designed to reduce such risk, including implementing co-billing arrangements with other local operators that allow
them to bill their local customers for Embratels long-distance fees, using call centers, implementing an automated collections system, employing an anti-fraud system, using third-party collection firms and implementing a customer data system
that allows for faster updating of information, flexibility in customer account structure, quality improvement and improved payment of taxes across the different Brazilian states.

Net Serviços bills its customers through monthly invoices that detail itemized charges and services, including monthly subscription
fees, broadband and Pay TV services and Embratels fixed-line voice services, as incurred by customers, in addition to applicable taxes. Accounts that are more than 30 days past due are considered disconnected, at which time Net Serviços
blocks the accounts signal. If the customer remains in arrears, Net Serviços proceeds to collect any equipment, such as set-top boxes, that may be located in the customers location. In addition, Net Serviços focuses on
customer service to reduce bad-debt expenses. In recent years, that strategy has proved successful, as bad debt as a percentage of sales constituted only 0.7% in 2011, 1.3% in 2012 and 1.4% in 2013.

Our Networks and Technology

Wireless Networks

Claro Brasil owns and operates wireless networks using GSM, 3G and LTE technologies. As of December 31, 2013, Claro Brasils GSM
network, which Claro Brasil continues to roll out, covered more than 3,646 cities and 91.6% of Brazils population. In addition, Claro Brasils 3G network, which was the first in Brazil and which Claro Brasil continues to roll out, covers
1,372 cities and 72.6% of Brazils population. Claro Brasils LTE network, which was the first in Brazil and which Claro Brasil continues to roll out, covers 60 cities and 29.9% of Brazils population.

Fixed-line Networks

Embratel owns the largest long-distance network in Latin America and the largest data-transmission network in Brazil. Embratels
long-distance and data-transmission networks use fiber optic, digital microwave, satellite and copper wireline technologies. Embratels networks use a 100% digital switching system for voice and data services and the latest generation Internet
Protocol (IP) routers to support IP-based services, internet access and VPNs, through Multiprotocol Label Switching technology. Embratels internet backbone is the largest in Latin America with 1,100 Gbps capacity distributed
through 2,921 points of presence and 59 routing centers, and its network also connects to the international internet backbone. Embratel also has approximately 63,346 kilometers of cable in a mesh network that has three or more outlets with a
capacity of 7.1 TbPs. Embratel has local metropolitan digital fiber networks with approximately 15,500 kilometers of cable in the major Brazilian cities and is attaching fiber extensions to commercial buildings connected to metropolitan rings,
providing high quality direct connections. Embratels submarine cable network reaches all continents through nine different cable systems in which it has various ownership interests. Embratels networks have also been modified to use Net
Serviçoss coaxial cable networks to provide telephony services to Net Serviçoss broadband customers through NET Fone. In December 2009, Net Serviços granted Embratel an indefeasible right to use its HFC network to
provide local fixed-telephone service.

To supplement its network, Embratel uses long-distance microwave systems, in areas where
installation of fiber cables is difficult, with a total range of 16,254 kilometers and seven satellites to provide services to remote locations within the country and it leases satellite capacity from international satellite systems and submarine
capacity in other private cable systems. Embratel also offers local telephony services to its Claro Fixo residential customers using CDMA wireless technology.

Net Serviços has an advanced network that uses coaxial and fiber optic technologies that allows it to provide a wide range of services
and products at bandwidth capacities of 450 MHz, 550 MHz and 750 MHz or above. Net Serviçoss network also helps it reduce piracy by enabling Net Serviços to scramble its signal in any of the homes through which the
network passes. Net Serviços also believes that its network is equipped to respond to future customer preferences, as it has bi-directional technology for almost all homes passed. The network also has in place the architecture necessary to
provide pay-per-view and video-on-demand services in additional regions once it becomes commercially viable to do so. As of December 31, 2013, Net Serviçoss network had over 109,484 kilometers of cable and passed approximately
18.8 million homes in 164 localities.

Satellite Network

Embratel and Star One have the most extensive satellite system in Latin America with a fleet covering the entire territory of South America and
Mexico, as well as part of Central America and part of Florida. Star One currently has seven satellites in full operation (i.e., in geostationary orbit), including one it owns jointly with SES. These satellites currently operate in the C-band and/or
Ku-band frequencies. Star One also operates two satellite control centers that are certified by the International Organization for Standardization.

Embratel and Star One have a program to replace satellites that are nearing or have reached the end of their contractual lives, thereby
ensuring the continuity and quality of their services. Pursuant to that program, Star One

successfully launched the C-3 satellite in November 2012 to replace the B-3 satellite. The C-3 satellite brought new Ku-band capacity over Brazilian territory and the Andean Region. In addition,
Star One entered into a contract with Space System/Loral, in January 2012 and July 2013, for the in-orbit delivery of two new satellites: (i) the Star One C4 satellite, to be launched in 2014, will provide Ku-band capacity; and (ii) the
Star One D1 satellite, to be launched in 2016, will provide C, Ku and Ka-band capacity. The Star One C4 satellite is primarily intended to supply capacity for DTH services for Claro TV throughout Brazil and in other DTH operations in South America.
The Star One D1 satellite will replace the B-4 satellite to expand Ku-band capacity in Brazil and South America as well as to initiate businesses by using the new Ka-band technology.

REGULATION

Mexico

Applicable Legislation

For the past two decades, the general legal framework for the regulation of telecommunications services in Mexico was governed by
the 1995 Federal Telecommunications Law (Ley Federal de Telecomunicaciones), which supplemented the General Communications Law (Ley de Vías Generales de Comunicación) enacted in the early 20th century, and by regulations adopted under both statutes.

Mexico is currently
developing a new legal framework for the regulation of telecommunications and broadcasting services, based on a package of constitutional amendments passed in June 2013. Among other things, the 2013 constitutional amendments:



| |  |  | established the IFT, an independent regulatory body with broad powers that replaced the Federal Telecommunications Commission (Comisión Federal de Telecomunicaciones, or Cofetel) as the primary
regulator of telecommunications companies and services;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | established specialized courts for telecommunications and broadcasting matters, and limited judicial powers to suspend regulatory measures while judicial reviews are pending; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | identified criteria for determining whether there is a preponderant economic agent in each of the telecommunications and broadcasting sectors, and certain asymmetric measures that may be imposed based on
such a determination to protect competition and consumers.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The June 2013 constitutional amendments contemplate implementing
legislation, and a bill for that purpose is currently under consideration in the Mexican Congress. We expect that the implementing legislation will be adopted in 2014, but we cannot predict the content of the final legislation. When the legislation
is enacted, it will establish a Federal Law on Telecommunications and Broadcasting (Ley Federal de Telecomunicaciones y Radiodifusión) to replace the existing statutory framework. In the discussion below, we refer to the implementing
legislation currently under consideration as the 2014 legislation.

We expect that the effects of the 2013 constitutional amendments and
the 2014 legislation on our business and operations in Mexico will be material, but the impact will depend in part on how they are implemented by further regulations and by other actions of the IFT. The long-term effects will also depend on how we
and our competitors adapt to the new regulatory framework, how customers behave in response, and how the telecommunications and media markets develop. It would be premature to predict the long-term effects of the emerging regulatory framework, but
they could be adverse to our interests in significant respects.

Principal Regulatory Authorities

The IFT is an autonomous authority that regulates telecommunications and broadcasting. It is headed by seven commissioners appointed by the
President, and ratified by the Senate, from among candidates nominated by an evaluation committee.

The IFT has authority over the
application of legislation specific to telecommunications and broadcasting, and also over competition legislation as it applies to those sectors. It succeeded to powers that were exercised before the 2013 constitutional amendments by the Ministry of
Communications and Transport (Secretaría de Comunicaciones y Transportes, or SCT), acting through Cofetel, and with respect to competition laws, the Federal Competition Commission (Comisión Federal de
Competencia).

##### Table of Contents

The Mexican government has certain powers in its relations with concessionaires, including the
right to take over the management of an operators networks, facilities and personnel in cases of imminent danger to national security, public order or the national economy, natural disasters and public unrest as well as to ensure continuity of
public services. Except in the event of war, the Mexican government must indemnify the title holder for damages and losses.

Telecommunications operators are also subject to regulation by the Federal Consumer Bureau (Procuraduría Federal del Consumidor,
or Profeco) under the Federal Consumer Protection Law (Ley Federal de Protección al Consumidor). This law regulates publicity, the quality of services and information required to be provided to consumers and provides a
mechanism to address consumer complaints. It also permits class actions for consumer claims. Profeco has the authority to impose fines, which can be significant.

Mobile Rates

Wireless services concessionaires generally are free to establish prices they charge customers for telecommunications services. Mobile rates
are not subject to a price cap or any other form of price regulation. The interconnection rates concessionaires charge other operators are also generally established by agreement between the parties, and if the parties cannot agree, may be imposed
by the IFT subject to certain guidelines, cost models and criteria. The establishment of interconnection rates has resulted in disputes between operators and with the IFT.

Notwithstanding the generally applicable regime, under the 2013 constitutional amendments, as well as related regulations, an operator that is
determined by the IFT to be a preponderant economic agent may not freely determine either interconnection rates or final tariffs. Under these provisions, Telcel is subject to additional requirements that will affect our ability to freely determine
the rates for telecommunications services. See Asymmetric Regulation of the Preponderant Economic Agent under this Item  4. The IFT is also authorized to impose specific rate requirements on any operator that is determined by
the IFT to have substantial market power under the Federal Antitrust Law. See Mexican Regulatory Proceedings under this Item 4.

Fixed Line Rates

Under Telmexs concession, Telmexs rates for basic telephone services in any period, including installation, monthly rent, measured
local-service and long-distance service, are subject to a ceiling on the price of a basket of such services, weighted to reflect the volume of each service provided by Telmex during the preceding period. Every four years, Telmex files a
model before both IFT, and the SCT, with its projections of units of operation for basic services, costs and prices. There is also a price floor based on Telmexs average long-run incremental cost. Within this aggregate price range, Telmex is
free to determine the structure of its own rates. Telmex must get permission from the IFT before its rates can take effect.

The price cap
varies directly with the Mexican National Consumer Price Index, allowing Telmex to raise nominal rates to keep pace with inflation (minus a productivity factor set for the telecommunications industry), subject to consultation with the IFT.
Telmex has not raised its nominal rates since March 2001, for local service, and since March 1999 for long-distance service. Under the concession, the price cap is also adjusted downward periodically to pass on the benefits of Telmexs
increased productivity to its customers. The IFT sets a periodic adjustment for every four-year period to permit Telmex to maintain an internal rate of return equal to its weighted average cost of capital. For services extending beyond basic
telephone service, Telmex is free to set its rates. These services include data transmission, directory services and services based on digital technology, such as caller ID, call waiting, speed dialing, automatic redialing, voice mail, as well as
three-way conference and call transfer.

During 2011, Cofetel notified Telmex of three resolutions mandating reductions to the
interconnection rates that Telmex charges to other telecommunications providers. Specifically, Cofetels resolutions reduced rates for 2011 by 65% for interconnection fees and 94% for transport of long-distance traffic (resale), when compared
to

##### Table of Contents

2010. Telmex has filed petitions to challenge these resolutions before Cofetel and resolution of these petitions is pending. In April 2013, Cofetel issued a resolution mandating a further
reduction in the 2012 interconnection fees.

Telmexs freedom under its concession to determine its rates is substantially
affected by the regulatory actions taken under the 2013 constitutional amendments. See Asymmetric Regulation of the Preponderant Economic Agent.

Concessions

Under
the applicable legislation, an operator of public telecommunications networks, such as Telcel or Telmex, must operate under a concession. The authority that grants concessions was previously the SCT and is currently the IFT. Concessions may only be
granted to a Mexican citizen or corporation and may not be transferred or assigned without the approval of the IFT.

There are two types
of concessions, as described below.



| |  |  | Network concessions. The 2013 constitutional amendments contemplate unified concessions (concesión única), each of which allows the holder to provide all types of telecommunications and
broadcasting services. Unified concessions were introduced to foster the convergence of networks that do not use frequencies of radio-electric spectrum. The constitutional amendments also provide for a transitory regime under which existing
concessions can be migrated to the new, unified concession regime. Telmex, and its subsidiary Telnor, hold network concessions granted under the pre-2014 regime to provide specified types of services. Their ability to migrate to the new regime, and
consequently to provide additional services, is subject to conditions, as described under Migration of Concessions below. Our competitors with a unified concession will be able to provide any and all telecommunications and
broadcasting services. A unified concession has a term of up to 30 years, extendable for up to an equal term.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Spectrum concessions. Telcel holds multiple concessions to provide wireless services that utilize frequencies of radio-electric spectrum. Each of these generally has a term of up to 20 years and may be extended
for additional 20-year terms.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

A public telecommunications concessionaire is required by law to establish an open-network
architecture that permits interconnection and interoperability.

Termination of Concessions

The Federal Telecommunications Law provides that at the expiration of a concession, the Mexican government has a right of first refusal to
acquire the assets used directly in the exploitation of the concession.

The General Communications Law provides that upon the expiration
of the Telmex concession the Mexican government is entitled to purchase its telecommunications assets at a price determined on the basis of an appraisal by a public official. Related telecommunications regulations provide that, upon expiration of
the concession, the Mexican government has a right of first refusal to acquire Telmexs telecommunications assets. However, the General Communications Law also provides that in certain cases, upon expiration of the concession, Telmexs
telecommunications assets will revert to the Mexican government free of charge. There is substantial doubt as to how these provisions of the General Communications Law and the telecommunications regulations would be applied and, accordingly, there
can be no assurance that upon expiration of the concession, Telmexs telecommunications assets will not revert to the Mexican government free of charge.

Migration of Concessions

The 2013 constitutional amendments provide for a unified concession under which an operator may provide any service of telecommunications or
broadcasting and for migration to the unified concession system. When Telmex can migrate to the new, unified concession regime, it may be able to provide Pay TV or broadcasting services.



47

##### Table of Contents

However, migration is subject to additional conditions for a predominant economic agent. Under
these provisions, before Telmex can migrate its current concession to a unified concession, certain specific requirements must be met, including: (i) payment of any new concession fee to be determined by the Ministry of Finance
(Secretaría de Hacienda y Crédito Público), (ii) compliance, with current requirements under the concession, the 2013 constitutional amendments, the measures imposed by the IFT on the preponderant economic agent and
any new obligations provided by law, and (iii) such other requirements, terms and conditions as the IFT may establish. Consequently Telmex may not be able to provide Pay TV or broadcasting services in the near term.

Telcel Concessions

Telcel operates under several different concessions covering particular frequencies and regions, holding an average of 72.8 MHz of capacity in
Mexicos nine regions in the 850 MHz, 1900 MHz and 1.7/2.1 GHz spectrum. The following tables summarize Telcels concessions.

In addition to the 850 MHz, 1900 MHz and 1.7/2.1 GHz concessions detailed in the tables above, in December
2002, the SCT granted Telcel a concession to install and operate a telecommunications network to provide national and international long-distance services, as well as data-transmission services. The concession was granted for an initial term of 15
years, and it is subject to extension for an additional 15-year period.

Renewal

The eight Band B concessions covering regions outside the Mexico City area were renewed in 2010 and 2011, with certain additional conditions
imposed on Telcel. Telcel challenged the imposition of some of these conditions in a proceeding that does not affect the validity of the renewals, and a final resolution of such challenge is still pending. All of these concessions are subject to
renewal for additional 15-year terms.

On April 20, 2010, Telcel requested the renewal of the Band B concession covering the Mexico
City area (Region 9) that will expire in October 2015, and that renewal request is still pending. The Band D concessions will expire in 2018, the Band A concessions in 2019, the Band F concessions in 2025 and the nationwide 1.7/2.1
GHz concession in 2030. All of these concessions are subject to renewal for equal terms.

Concession Fees

In addition to the upfront payment applicable to all of the 1900 MHz (F Band) concessions, 1.7/2.1 GHz (B2, C and D Bands) concessions and 850
MHz concessions (Regions 1 to 8), owners of concessions granted or renewed on or after January 1, 2003 are also required to pay annual fees (derechos) for the use and exploitation of radio spectrum bands. The amounts payable are set
forth by the Federal Annual Fees Law (Ley Federal de Derechos) and vary depending on the relevant region and radio spectrum band. Currently, Telcel is not required

##### Table of Contents

to pay these fees for its Bands A and D 1900 MHz concessions since they were awarded prior to 2003, but it is required to pay them for additional 10 MHz of capacity in the 1900 MHz spectrum
(Band F) acquired in 2005. The renewal of the Band B concessions in 2010 and 2011 required Telcel to pay an aggregate upfront fee of Ps.74.8 million, as well as to make payments of annual fees (derechos) during the term of the
concessions. The grant of the nationwide 1.7/2.1 GHz concession for a 20-year term, which occurred in October 2010, required an upfront payment of Ps.3,793 million.

Service Quality Requirements

The concessions set forth extensive requirements for the quality and continuity of Telcels services, including, in some cases, maximum
rates of incomplete and dropped calls and connection time. In 2011, Cofetel issued a new Fundamental Technical Plan for Quality of Local Mobile Services (Plan Técnico Fundamental de Calidad del Servicio Local Móvil, the
2011 Technical Plan). The 2011 Technical Plan is applicable to all mobile operators, including Telcel. The 2011 Technical Plan imposes additional service quality requirements for voice, SMS and internet services to those set forth in our
concessions, and includes a methodology based on site measurements that may be publicly available and potential fines for non-compliance with voice-quality requirements. We believe we are in compliance with the service quality requirements of our
concessions and of the 2011 Technical Plan. Nonetheless, Telcel has been notified that the SCT has commenced a number of proceedings seeking to impose penalties on Telcel on the basis of alleged non-compliance with the service quality requirements
of the previous technical plan, as well as some proceedings from alleged service quality non-compliance during network failures. Telcel is challenging the allegations and penalties in proceedings that are still pending.

Telmex Concessions

Telmexs concession was granted in 1976 and amended in August 1990. Currently set to expire in 2026, Telmexs concession may be
extended for an additional 15-year term subject to additional requirements that the IFT may impose. Thereafter, it may be renewed for successive 30-year terms. Telmexs subsidiary, Teléfonos del Noroeste, S.A. de C.V.
(Telnor), holds a separate concession in a region located in two states in northwestern Mexico that will expire in 2026 and may be extended for an additional 15-year term thereafter. The material terms of the Telnor concession are
similar to those of the Telmex concession.

In addition, Telmex currently holds concessions for the use of frequencies to provide wireless
local access and point-to-point and point-to-multipoint transmission. Telmex obtained these concessions from Cofetel through a competitive bidding process for a term of up to 20 years that may be extended for additional 20-year terms.

Asymmetric Regulation of the Preponderant Economic Agent

Determination

The 2013
constitutional amendments provide for the IFT to determine whether there is a preponderant economic agent in the telecommunications sector and, if so, authorize the IFT to impose a special regulatory regime on the preponderant economic
agent. The special regime is referred to as asymmetric regulation, because it applies to one market participant and not to the others.

The 2013 constitutional amendments provided a deadline for the determination and for the imposition of asymmetric regulation, but they also
contemplated that both would occur after the adoption of implementing legislation. In March 2014, the IFT determined that an economic interest group consisting of us and our operating subsidiaries Telcel, Telmex and Telnor, as well as
Grupo Carso, S.A.B. de C.V. and Grupo Financiero Inbursa, S.A.B. de C.V., constitutes the preponderant economic agent in the telecommunications sector. The 2013 constitutional amendments provide that a determination of preponderance can
be based on number of customers, traffic or network capacity, and the IFTs determination was based on a finding that we serve more than half of the customers in Mexico as measured by the IFT on a national basis.



49



---

##### Table of Contents

The IFT also imposed extensive asymmetric regulations on our Mexican fixed-line and wireless
businesses, as summarized below. Certain of these measures took effect in April 2014. We have begun judicial proceedings to challenge the determination of preponderant economic agent and the related measures, but under the 2013 constitutional
amendments no interim relief from the regulations is available pending judicial consideration of our challenges.

Specific Measures

Based on its determination that we and our Mexican operating subsidiaries constitute a preponderant economic agent in the
telecommunications sector, the IFT imposed extensive specific asymmetric measures, which it considered necessary to avoid effects on competition and telecommunications markets. Some of the most important measures are summarized below.



| |  |  | Interconnection. The interconnection rates we charge to other operators are set by the IFT at rates below those charged by the other operators. The IFT also adopted a model interconnection agreement
(convenio marco de interconexión). In March 2014, the IFT imposed on Telcel the interconnection rate it must charge to all other operators for traffic to Telcels network from April 6, 2014 to December 31, 2014. The rate
charged was reduced from Ps.0.3490 to Ps.0.2045 per minute.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Access to Infrastructure. Several measures relate to the ability of other operators to use our network infrastructure.
| | - |  | ----------------------------------------------------------------------------------------------------------------------

Sharing of Infrastructure. We must provide other operators access to use our passive infrastructure, including towers,
sites, ducts and rights of way. Access rates are to be negotiated with the operators or, if agreement cannot be reached, determined by the IFT using a long-run average incremental costs methodology.

Local Loop Unbundling. We must offer other operators access to elements of our local network separately. Access rates
will be determined by the IFT using a methodology of long run average incremental costs. We have until June 30, 2014 to submit to the IFT our proposed offer of unbundled access, and by November 30 of each year we must publish the offer. We
must also agree on an unbundling agreement with any other operator.

Leasing of Dedicated Links. We must lease
dedicated links to other operators. The rates are to be negotiated with the operators or, if agreement cannot be reached, determined by the IFT using a retail minus methodology, except for dedicated-link leasing for interconnection
services where the IFT will use a long-run average incremental costs methodology.

Mobile Virtual Network
Operators. We must provide mobile virtual network operators access to services we provide to our customers, at rates to be negotiated with the operators or, if agreement cannot be reached, determined by the IFT using retail minus
methodology.



| |  |  | Roaming. We must provide roaming services at a national level to the other mobile operators, and if agreement cannot be reached, the IFT will determine the rate using a long-run average incremental costs
methodology. Rates for wholesale roaming services will be negotiated with the other operators or, if agreement cannot be reached, determined by the IFT using a long-run average incremental costs methodology.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Elimination of Domestic Roaming Charges. We may no longer charge our customers roaming charges within Mexico.
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | Certain Obligations on the Provision of Retail Services. Certain rates for the provision of telecommunications services to our subscribers are subject to rate control or authorization by the IFT, using
methodologies related to maximum prices and replicability tests that are currently under analysis by us and the IFT. Also, we are subject to various obligations relating to the sale of services and products, including the obligation to offer
individually all services that are offered under a bundle scheme, limitations on exclusivity for handsets and tablets, and the obligation to unlock handsets.

Termination of Asymmetric Regulation

The specific measures of asymmetric regulation can be terminated if the IFT declares that effective competition conditions exist in the
telecommunications sector or if we cease to be considered a preponderant economic agent. The measures will be reviewed for this purpose every two years.

Mexican Regulatory Proceedings

We are subject to certain regulatory proceedings, as described below, but we expect them to be superseded in part by the 2013 constitutional
amendments, measures issued by the IFT and implementing legislation that we expect will be adopted in 2014.

Telcel Antitrust
InvestigationsSubstantial Market Power

Telcel is the target of two substantial market power investigations initiated by Cofeco.
The investigations are now being conducted by the IFT, which under the 2013 constitutional amendments is exclusively responsible for enforcing competition legislation with respect to telecommunications and broadcasting. In the first investigation,
Cofeco determined that Telcel had substantial market power over the mobile termination switched services it provides to other concessionaries through its network. The second investigation determined that Telcel had substantial market power in the
nationwide market for voice and data services. Telcel filed challenges (juicios de amparo) to both determinations. Resolution of both challenges is pending.

These determinations, if upheld, would allow the IFT to impose against Telcel specific requirements as to rates, quality of service and
information, though it has not yet done so. If it does, we expect to challenge the IFTs rulings.

Telcel Antitrust
LitigationsMonopolistic Practices

In April 2011, following a regulatory inquiry initiated in 2006, Cofeco notified our
subsidiary Telcel of a resolution imposing a fine of Ps.11,989 million for alleged relative monopolistic practices (prácticas monopólicas relativas) that also, allegedly, constituted a repeat offense
(reincidencia). Under applicable Mexican law, Cofeco would have been able to impose a penalty for a repeat offense equivalent to the highest of twice the fine applicable to a first-time offense, or 8.0% of the offenders annual revenues
for its previous fiscal year.

In May 2012, Cofeco revoked the fine. As a condition to the revocation of the fine, Telcel must comply with
the following undertakings that it proposed to Cofeco in March 2012: (i) the gradual reduction of the mobile termination rate Telcel charges for termination of voice traffic in its network to reach Ps.0.3094 in 2014; (ii) use of the second
as the applicable unit for measuring interconnection rates; (iii) publication of the reference interconnection terms (oferta pública de interconexión) applicable to its network; (iv) termination of all pending disputes
related to the 2011 termination rate (Ps.0.3912) determined by Cofetel with those operators that agree to enter into an agreement based on the reference interconnection terms; (v) maintenance, as part of Telcels

commercial offerings, of plans or promotions under which some of the minutes included in the plan or promotion can be used by the Telcel customer to call any fixed or mobile network at the same
rate (without differentiating on-net and off-net); and (vi) an access to information agreement under which Cofeco can monitor compliance with Telcels undertakings.

The IFT is now responsible for monitoring Telcels compliance with respect to the undertakings listed above and in the event of any
breach, may impose a fine of up to 8.0% of Telcels annual revenues. Six other operators challenged the revocation of the fine, and four of those proceedings have now been resolved on terms favorable to Telcel. See Legal Proceedings
under Item 8 and Note 17 to our audited consolidated financial statements included in this annual report. As a result of the changes to the legal regime governing Mexican telecommunications services, the mobile termination rates Telcel will
charge during 2014 will be lower than those agreed upon with Cofeco.

Telmex Antitrust InvestigationsSubstantial Market Power

Beginning in 2007, Cofeco initiated four investigations to evaluate whether Telmex and its subsidiary Telnor have substantial power in
certain markets. Cofeco issued final resolutions concluding that Telmex and Telnor have substantial power in all four of the relevant markets investigated. Telmex and Telnor submitted petitions for reconsideration (recursos de
reconsideración) to Cofeco challenging their findings. Cofeco denied the petitions for reconsideration. Telmex and Telnor then filed challenges (juicios de amparo indirecto) to Cofecos denial of the petitions for
reconsideration. Of these challenges, two are still pending, but two of Telnors challenges have been denied, effectively upholding Cofecos findings. With respect to the matters for which the challenges were denied, Cofetel can impose
specific tariff requirements or other special regulations, such as additional requirements regarding disclosure of information or quality of service. Consequently, in April 2012, Cofetel published an agreement in the Official Gazette, establishing
requirements regarding tariffs, quality of service, and information for dedicated-link leasing. Telmex believes it could have an adverse impact on its revenues and results of operations. Telmex and Telnor have filed a petition for relief against
that resolution, and that petition is still pending. See Note 17 to our audited consolidated financial statements included in this annual report.

Mobile Termination Rates

Under the calling party pays system, when the customer of one operator (local or long-distance) places a call to a customer of another
operator, the first operator pays the second a fee, which is referred to as an interconnection fee or mobile termination rate. Under Mexican law, interconnection fees are negotiated between operators. There has been extensive controversy in Mexico
concerning the mobile termination rates payable to mobile operators since 2005, and the new legal framework imposes specified interconnection rates on Telcel. See Mobile Rates under this Item 4 and Note 17 to our audited
consolidated financial statements included in this annual report.

February 2009 Interconnection and Interoperability Plan

In February 2009, Cofetel published a Fundamental Technical Plan of Interconnection and Inter-operability (the 2009 Plan) that
addresses the technical, economic and legal conditions of interconnection and establishes additional obligations on telephone services providers, including Telcel, Telmex and Telnor. With respect to mobile termination fees, the 2009 Plan establishes
a process for developing an economic model over a relatively brief period and then applying the economic model to set fees, which could override the existing fee agreements among service providers. Telcel believes that the implementation of the 2009
Plan will result in asymmetric and discriminatory treatment for those service providers that Cofeco (and under the new legal framework, the IFT) has determined are dominant. It will also subject these service providers to specific technical and
legal requirements and different economic, technical and legal conditions than the other service providers, such as the

disaggregation of network components. Accordingly, Telcel, Telmex and Telnor have challenged the 2009 Plan, and their challenges are pending as of the date of this annual report. We are unable to
predict the competitive and financial effects that might result if those challenges are resolved against us and the 2009 Plan is implemented, though they could materially reduce our revenues in future periods.

Consolidation of Local-service Areas

In 2005, Cofetel issued guidelines regarding the consolidation of local-service areas. Following a legal challenge by Telmex, the guidelines
were withdrawn in June 2012. On July 1, 2013, Cofetel issued a resolution that would decrease the number of local-service areas, which would result in a reduction in our revenues from long-distance calls. Additionally, we would have to invest
in adapting our technology to the changes in fixed-number dialing that the guidelines contemplate. As a result of the new legal framework, after a three-year period ending in 2017, local-service areas will be eliminated and all calls within Mexico
will be considered local calls.

IFT DeterminationPreponderant Economic Agent

On March 6, 2014, the IFT issued a resolution declaring that we and certain of our subsidiaries and affiliates comprise an economic
interest group, declaring that this group constitutes a Preponderant Economic Agent and imposing specific asymmetric regulations. On March 31, 2014, we and our operating subsidiaries, Telcel and Telmex, each filed a challenge (juicio de
amparo) against the IFTs resolution, which are still pending. The new legal framework prevents us from obtaining a temporary judicial suspension of the asymmetric regulations. See Asymmetric Regulation of the Preponderant
Economic Agent under this Item 4.

Brazil

Legislation and Main Regulatory Authorities

The Brazilian Telecommunications Law (Lei Geral das Telecomunicações Brasileiras) provides a framework for
telecommunications regulation. The primary telecommunications regulator in Brazil is Anatel, which has the authority to grant concessions and licenses for all telecommunications services, except broadcasting, and to propose and issue regulations
that are legally binding on telecommunications services providers.

The principal tax imposed on telecommunications services is a state
level value-added tax (Imposto Sobre Ciculação de Mercodorias e Serviços), which Brazilian states impose on gross revenue derived from telecommunications services, and which varies from state to state, but averages 27%
nationwide.

Rates

Anatel regulates rates for telecommunications services. In general, PCS license-holders are authorized to increase basic plan rates only
annually and to adjust for inflation (less a factor determined by Anatel based on the productivity of each operator during the year). Embratels concession for both domestic and international long-distance services allows it to set its own
rates freely as in accordance with an annual rate-adjustment mechanism established by Anatel. In December 2012, Embratel obtained Anatels approval to set international long-distance rates freely as it deems appropriate, provided it gives
Anatel and the public advance notice. Data transmission rates are not regulated.

General Regulatory Plan

The General Regulatory Plan (Plano Geral de Atualização da Regulamentação, or PGR), issued in
October 2008, serves as the framework to develop public telecommunications policies for a period of ten years. The PGR includes Anatels plans to regulate MVNOs practices, expand broadband services to rural and low-income areas, implement
rules related to fixed-line incumbents infrastructure usage within the next two years and revise the rules related to the size of the areas where service is considered to be local.

Under the PGR, in 2012 Anatel auctioned 4G spectrum frequencies with coverage obligations that aim to expand broadband access to rural and
low-income areas. In this auction, Claro was awarded one of the two available nationwide licenses with a higher capacity (20+20 MHz in the 2.5 GHz band) that will allow it to provide faster data speeds. In additional to the national spectrum block,
Claro also acquired 19 regional complementary blocks (10+10 MHz).

New Pay TV Legal Framework

In September 2011, the Brazilian Congress approved a new legal framework applicable to all Pay TV operators in Brazil. The new framework, among
other things, allows new entrants into the Pay TV market, including telephone companies; permits existing Pay TV operators to migrate to the new regulatory regime even in cases where their current license contracts are still in full force and
effect; establishes that no license renewal requests, transfer of control requests, or changes in corporate structure requests will be granted unless existing Pay TV operators convert their old licenses to new licenses governed by the new legal
framework; establishes Brazilian content quotas; and requires operators to provide free access to certain local and municipal channels. Anatel issued the main regulations regarding the new legal framework in March 2012. All licenses have national
coverage and operators are not permitted to have multiple Pay TV licenses.

Concessions (Authorizations)

Our Brazilian wireless subsidiaries hold licenses to provide services under the PCS regime in the 450 MHz, 850 MHz, 900 MHz, 1,800 MHz, 1,900
MHz, 2,100 MHz and 2,500 MHz spectrum bands. Our subsidiaries expect to continue to acquire spectrum as Anatel conducts additional auctions.

into eight Pay TV (SeAC) licenses, which allow Net Serviços to provide services in over 160 cities. These licenses impose certain technical, financial and legal requirements and have no expiration date. In 2014, Net Serviços intends to
waive seven of such licenses and provide its services through a single nationwide license.

Claro Brasil is required to pay a biannual fee equal to 2.0% of net revenue, except for the final year of the 15-year term of its
authorizations, in which the fee equals 1.0% of net revenue.

Embratel is required to pay a fee every two years during the term of its
domestic and international long-distance concessions equal to 2.0% of the revenues from switched fixed telephone services, net of taxes and social contributions, for the year preceding the payment.

Wireless Interconnection Fees

Mobile termination rates in Brazil are negotiated by operators, subject to the condition that wireless operators offer to all other fixed-line
and wireless operators the best rates offered to any fixed-line operator. Our Brazilian subsidiaries have not always been able to reach agreements on the mobile termination rates with certain operators and some of these operators have sought the
intervention of Anatel or the Economic Defense Department. We expect that mobile termination rates will continue to be the subject of litigation and administrative proceedings. We cannot predict when or how these matters will be resolved. The
competitive and financial effects of any adverse resolution of these proceedings could be complex and difficult to predict, but if the rates set as a result of these proceedings are different from the ones Claro Brasil has agreed to with most
operators, Claro Brasil may suffer a financial impact.

In 2005, Anatel defined a series of cost-based methods for determining
interconnection fees charged by operators belonging to an economic group with significant market power. Anatel has proposed that an economic group with more than 20% of market share shall be considered to have significant market power for this
purpose. Under this proposal, Claro Brasil would be an economic group with significant market power.

In November 2012, Anatel published
Resolution N. 600, approving the General Plan of Competition (Plano Geral de Metas da Competição or PGMC), which establishes that mobile termination rates must be reduced: (i) to 75% of the 2013 rates by 2014;
and (ii) to 50% of the 2013 rates by 2015. In 2016, mobile termination rates

will be determined based on a cost model, which is intended to be submitted during 2014. If Claro Brasil is deemed to constitute an economic group with significant market power and if PGMC comes
into force as described, Claro Brasil may suffer a financial impact.

During the first quarter of 2012, in order to decrease the
interconnection fees while PGMC comes into force, Anatel issued a transitory regulation that imposes a reduction of interconnection fees. Although the financial effect on Embratel is unclear, such regulation had a negative impact on Claro Brasil.

Fixed Line Interconnection Fees

Fixed line operators may freely negotiate interconnection rates, subject to a price cap established by Anatel. However, if an operator offers
an interconnection fee below the price cap to another operator, it must offer the same price to any other operator that requests it.

Competition Regulation

The PGMC published by Anatel sets forth competition goals for all main telecommunications services. Their key objective is to lower prices in
the wholesale markets and to ensure equal treatment among competitors. In December 2012, Anatel held public consultations regarding reference prices for such regulated markets and resolved that wholesale contracts within these markets shall be
overseen by a third-party company hired by all the main operators. Anatel approved both Claro Brasils and Embratels wholesale public offerings (roaming, infrastructure, leased lines, mobile interconnection fees, internet network
interconnection and internet links).

Quality of Service Regulation

Telecommunications providers are subject to quality targets under their concessions and the Quality of Service Regulation (Regulamento de
Gestão da Qualidade or RGQ), issued in December 2012. Under this regulation, which came into force 120 days after its publication, the number of quality indicators fell from 37 to 21 for operators with more than
50 thousand accesses, thereby promoting the regulatory asymmetry already used in the regulation of broadband quality.

Noncompliance
with the targets set by the RGQ and other quality of service regulations may result in the imposition of penalties by Anatel. As such, in July 2012, Anatel suspended Brazilian mobile phone providers TIM, Claro and Oi from selling new telephone lines
in some states throughout the country, due to high rates of customer complaints. In each state, the company with the highest number of complaints was prohibited from conducting sales. Claro was prohibited from conducting sales in São Paulo,
Santa Catarina and Sergipe from July 2012 through August 2012.

As a result, operators were requested to present to Anatel an investment
plan that tackled issues of customer service and quality. Claros plan is being monitored by Anatel and non-compliance may result in further suspensions or other actions.

In October 2011, Anatel published quality of service regulations for PCS and SCM, which included new quality standards for broadband services.
In addition, it requires that an independent third party designated by all broadband service providersfixed and wirelessreview these new standards. During 2012, operators hired a third-party company whose measurements started to be
submitted during 2013.

Reversible Assets

Embratels concessions provide that the concessionaires assets, such as equipment, infrastructure and any other property or rights
essential for the provision of services and considered as reversible, cannot be disconnected, replaced or sold without prior regulatory approval. Upon expiration of these concessions, such assets may be reverted to the Brazilian government in
exchange for some compensation for the investments made in those assets.

Colombia

The ICT Ministry (Ministerio de Tecnologías de la Información y las Comunicaciones) and the Communications Regulatory
Commission (CRC) are responsible for overseeing and regulating the telecommunications sector, including wireless operations. In addition, the main audiovisual regulatory authority in Colombia with respect to Pay TV is the National
Television Authority (Autoridad Nacional de Televisión, or ANTV). The ICT Ministry supervises and audits the performance of our fixed and mobile voice and data services and the performance of legal, contractual and
regulatory obligations. The activities of Comcel and Telmex Colombia are also supervised by the Colombian Superintendency of Industry and Commerce (Superintendencia de Industria y Comercio), which enforces antitrust rules and protects
consumer rights.

In September 2011, the CRC opened an administrative action to impose new regulatory measures on Comcel because of its
dominant position in the outgoing mobile services market. On December 31, 2012, the CRC issued Regulation 4050/2012, which seeks to correct an alleged market failure, and imposed the following measures on Comcel: (i) asymmetric access
charges for call termination on Comcels network, whereby we must offer lower rates to our competitors than the rates we pay them; and (ii) restrictions on the rates we charge our users for calls outside our network (off-net calls), which
must not exceed the rates we charge for calls within our network (on-net calls). Asymmetric access charges are expected to end by January 1, 2015, while the restrictions on off-net rates are expected to be temporary, subject to review or
elimination by the CRC.

In October 2012, the ANTV issued Resolution No. 0179, establishing a unified licensing system and allowing
existing cable operators to apply for a unified license to provide Pay TV services on a neutral technology basis, and on October 7, 2013, an addendum was signed authorizing the Company to provide Pay TV services under the DTH method.

On March 11, 2013, the ICT Ministry issued Resolution No. 449, outlining the bidding process for its 4G licenses. Comcel was
excluded from bidding for the 1.7/2.1 GHz (AWS) spectrum band, but was allowed to bid for the 1.9 GHz and the 2.5 GHz spectrum bands. The 4G license auctioned to Comcel in the 2.5 GHz band was issued on July 26, 2013.

Under the terms of Comcels concessions to provide wireless telecommunications services in Colombia, it is required to make quarterly
royalty payments based on its revenues to the ICT Ministry. In October 2012, a draft bill restricting any one wireless provider from controlling more than 30% of the wireless market was proposed in the Colombian Congress, though the initiative was
not approved.

On November 28, 2013, Comcel qualified under the provisions of Law 1341 of 2009 related to the general authorization
for the provision of mobile services, and applied for inclusion in the register of ICT Ministry networks and services administrated by the ICT Ministry.

In February 2014, the Colombian Constitutional Court issued judgment C-555 of 2013, regarding the obligation of telecommunications providers
to return to the State assets related to their concessions upon the expiration of such concessions. The Constitutional Court ruled that Laws 422 of 1998 and 1341 of 2009 are constitutional and repealed the obligation to return such assets to the
State, stating that mobile operators would only be required to return the assets for concessions that were assigned prior to 1998. Additionally, the Constitutional Court indicated that the providers may be compensated for the return of assets. The
ICT Ministry will establish the applicable methodology to be followed for any such compensation.

In March 2014, the ICT Ministry
issued Resolution No. 598, which granted Comcel the renewal of its permits for the use of the radio spectrum required to provide mobile services and microwave links for an additional ten-year period.

Southern Cone

Argentina

The main
telecommunications regulatory authorities in Argentina are the Communications Ministry (Secretaría de Comunicaciones) and the National Communications Commission (Comisión Nacional de Comunicaciones), both of which are
under the authority of the Ministry of Federal Planning, Public Investment and Services of the National Government.

AMX Argentina holds
licenses covering the entire Argentine territory. These licenses contain coverage, reporting and service requirements, but do not have a fixed expiration date. The Communications Ministry is in charge of supervising the telecommunications industry
in Argentina and is authorized to foreclose and sell the shares of a licensee in case of specified breaches of the terms of a license.

During 2010, the Communications Ministry issued Resolution 98/2010 setting rules for the implementation of mobile number portability, which
began in March 2012. In November 2013, the Communications Ministry updated and modified the portability procedure through Resolution 21/2013.

Pursuant to Decree 558/08 all telecommunications providers, including AMX Argentina and Telmex Argentina, must contribute 1% of their monthly
revenues, determined after certain deductions, to the Universal Fund (Fondo Fiduciario del Servicio Universal) to finance the provision of telecommunication services in underserved areas and to underserved persons.

In July 2013, the Communications Ministry through Resolution 5/2013 established a Quality Regulation of Telecommunications Services standard,
under which providers must ensure better quality of service in terms of both accessibility to the network and dropped calls. The final document was issued by the National Communications Commission in November 2013.

In December 2013, the Communications Ministry issued Resolution 26/2013 which established the second as the unit of measure for
charges of mobile communications.

Chile

The General Telecommunications Law of 1982, as amended, established the legal framework for the provision of telecommunications services in
Chile. The law established the rules for granting concessions and permits to provide telecommunications services and for the regulation of rates and interconnection. The main regulatory agency of the telecommunications sector is the Chilean
Transportation and Communications Ministry (Ministerio de Transportes y Telecomunicaciones), which acts primarily through the Undersecretary of Telecommunications.

Claro Chile holds a concession covering the entire Chilean territory. The concession was granted in June 1997 and covers a thirty-year period. The concession imposes coverage, reporting and service quality requirements. The Chilean Transportation and Communications Ministry is authorized to foreclose any concessionaire in the event of
specified breaches of the terms of the concession.

In May 2006, Claro Chile acquired from Telefónica Móviles a concession
for the use of 25 MHz within the 850 MHz frequency that permits Claro Chile to increase the wireless services it provides. The term of this concession is for a 25-year period for the Metropolitan area and Region V and for an indefinite period for
the rest of Chile. In 2011, Claro Chile was granted a concession for the use of 40 MHz within the 2600 MHz frequency and in 2014 is expected to be granted a license in the 700 MHz frequency for a thirty-year period.

One of our subsidiaries has the right to use licenses to provide local fixed and wireless service
through 50 MHz of the 3.4 to 3.6 GHz frequency band throughout the country. In addition, some subsidiaries in Chile provide domestic and international long-distance service, data services, internet access, pay television services and value-added
services.

Paraguay

The National Telecommunications Commission of Paraguay (Comisión Nacional de Telecomunicaciones de Paraguay) is in charge of
supervising the telecommunications industry in Paraguay. It is authorized to cancel licenses in case of specified breaches of the terms of a license.

AMX Paraguay holds a nationwide PCS license to operate in the 1900 MHz frequency spectrum for a five-year term starting on January 26,
2009, which was renewed in April 2014 for an additional five-year period. AMX Paraguay also holds a nationwide internet access and data transmission license, which was renewed through 2017. In November 2010, AMX Paraguay received a license for a
five-year term to provide DTH services and in August 2011, AMX Paraguay received a license to provide cable TV services for a ten-year term. The licenses are renewable, subject to regulatory approval, and contain coverage, reporting and service
requirements. In December 2010, the National Telecommunications Commission of Paraguay approved the regulation for number portability, which was implemented during the fourth quarter of 2012.

Uruguay

The
Regulatory Unit of Communications Services (Unidad Reguladorada de Servicios de Comunicaciónes) and the National Administration of Telecommunications (Administración Nacional de Telecomunicaciones) are in charge
of supervising the telecommunications industry in Uruguay. In June 2004, we acquired a twenty-year license to operate three broadband PCS frequencies in Uruguay.

On February 4, 2013, Flimay was notified by the Court of Administrative Disputes (TCA) that its license for the provision of
DTH had become effective. In May 2013, administrative authorities revoked the aforementioned license. Flimay lodged an appeal against such administrative resolution that is still pending.

In March 2013, the Government called for a public bidding process for the frequencies in the 1900 MHz and 1700/2100 MHz radio spectrum. As a
result of this bidding process, AMX Wireless Uruguay was granted the use of 20 MHz of spectrum in the 1,900 MHz band and 20 MHz in the 1,700-2,100 MHz band.

In 2008, Conecel renewed its concessions to operate 25 MHz on the 850MHz radio spectrum and 10
MHz on the 1900 MHz (Sub Band E-E) radio spectrum. This included a concession for PCS services that expires in August 2023. The renewal of the PCS concession allows us to provide 3G services and contains stricter quality-of-service requirements for,
among other things, the number of successful call completions, average delivery time of SMS services, average time an operator takes to deal with all aspects of a customer call, geographic coverage and service conditions. In 2011, Conecel renewed
its license to provide internet value-added services, which expires in 2021. In 2002, Conecel obtained a license to provide carrier services, which expires in 2017.

In 2013, Conecel, through DTH, obtained a license to operate Pay TV services throughout Ecuador except for the Galapagos Islands. The license
expires in 2023.

Ecuador Telecom holds a concession to offer wireless and fixed-line voice, public telephony and domestic and
international long-distance carrier services, as well as a license to use the 3.5 GHz frequency band that expires in August 2017 and a Pay TV license that expires in 2018.

In February 2014, following a regulatory claim filed in 2012 by the state-owned operator, the Superintendency of Control of Market Power
(Superintendencia de Control del Poder del Mercado or SCPM) imposed a fine on Conecel of Ps.1,809 million (US$138.4 million), for alleged monopolistic practices related to five locations in which the state-owned operator argues
that Conecel has exclusive rights to deploy its network, preventing others from doing so. In March 2014, Conecel challenged the fine and posted a guarantee for 50% of its value. Through a judicial order issued during that same month, the competent
court allowed Conecels lawsuit and suspended the effects of the contested fine. In addition, our subsidiaries in Ecuador face other processes before the local regulatory authorities.

Peru

The main
telecommunications regulatory authorities in Peru are the Supervising Agency of Private Investment in Telecommunications (Organismo Supervisor de Inversión Privada en TelecomunicacionesOSIPTEL) and the Ministry of Transportation
and Communications (Ministerio de Transportes y Comunicaciones).

América Móvil Perú holds nationwide
concessions to provide mobile, PCS, fixed-line, local carrier, domestic and international long-distance, Pay TV services (through DTH and HFC technologies), public telephony and value-added services (including internet access) covering all regions
in Peru. The concessions were awarded between May 1999 and June 2008, operating 25 MHz on the 850 MHz band, 35 MHz on the 1900 MHz band, 50 MHz on the 3.5 GHz band, 10 MHz on the 450 MHz band and 56 MHz on the 10.5 GHz band.

Each of the concessions was awarded by the Ministry of Transportation and Communications, and covers a 20-year period. The concessions contain
coverage, reporting, service requirements and spectral efficiency goals. The Ministry of Transportation and Communications is authorized to cancel any of the concessions in case of specified breaches of its terms.

Mobile number portability was implemented in January 2010. During 2013, transfer requests from other wireless operators to América
Móvil Perú represented 52.5% of total portability requests.

Introduction

Segments

We have
operations in 18 countries, which are grouped for financial reporting purposes in nine segments. Our operations in Mexico are presented in two segmentsMexico Wireless, which comprises principally Telcel, and Mexico Fixed, which consists of
Telmex and its subsidiaries providing fixed-line services. Our headquarters operations are allocated to the Mexico Wireless segment. Segment information is presented in Note 21 to our audited consolidated financial statements.

Factors that drive financial performance differ for our different geographical segments, depending on subscriber acquisition costs, the
competitive situation, the regulatory environment, economic factors, interconnection rates and many other factors. Accordingly, our results of operations in each period reflect a combination of different effects on the different segments.

Constant Currency Presentation

Our financial statements are presented in Mexican pesos, but our operations outside Mexico account for a significant portion of our revenues.
Currency variations between the Mexican peso and the currencies of our non-Mexican subsidiaries, especially the Brazilian real, affect our results of operations as reported in Mexican pesos. In the following discussion regarding our operating
revenues, we include a discussion of the change in the different components of our revenues between periods at constant exchange rates, i.e., using the same exchange rate to translate the local-currency results of our non-Mexican operations for both
periods. We believe that this additional information helps investors better understand the performance of our non-Mexican operations and their contribution to our consolidated results.

Effects of Exchange Rates

Our results of operations are affected by changes in currency exchange rates. As discussed above, currency variations between the Mexican peso
and the currencies of our non-Mexican subsidiaries, especially the Brazilian real, affect our results of operations as reported in Mexican pesos. In 2013, the Mexican peso was generally stronger against our other operating currencies than in 2012,
which tended to reduce the reported amounts attributable to our non-Mexican operations.

We also recognize exchange gain and loss
attributable to changes in the value of our operating currencies, particularly the Mexican peso and Brazilian real, against the currencies in which our indebtedness and accounts payable are denominatedespecially the U.S. dollar. Appreciation
of our operating currencies generally results in foreign exchange gains, while depreciation of these currencies generally results in foreign exchange losses. Changes in exchange rates also affect the fair value of derivative financial instruments
that we use to manage our currency-risk exposures, which are generally not accounted for as hedging. In 2013, the Mexican peso and especially the Brazilian real weakened against the currencies of our indebtedness, and we recorded net foreign
exchange losses of Ps.19.6 billion and net fair value gains on derivatives of Ps.5.9 billion. In 2012, we recorded net foreign exchange gains of Ps.7.4 billion and net fair value losses on derivatives of Ps.5.3 billion. See Note 11 to our audited
consolidated financial statements.

Effects of Regulation

We operate in a regulated industry. Our results of operations and financial condition have been, and will continue to be, affected by
regulatory actions and changes. In recent periods, for example, regulators have imposed or sought to impose decreases in, or the elimination of, interconnection rates, and we expect further decreases in Mexico, Brazil, Chile, Peru, Ecuador and
Colombia. Lower interconnection revenues have often been offset by increased traffic resulting from lower effective prices to customers, but this may change. Significant regulatory developments are presented in more detail in Recent
Developments and Regulation under Item 4, and Risk Factors under Item 3.

##### Table of Contents

Composition of Operating Revenues

During 2013, our total operating revenues consisted of: mobile voice revenues (33.7% of total operating revenue), fixed voice revenues (14.2%
of total operating revenue), mobile data revenues (20.3% of total operating revenue), fixed data revenues (10.8% of total operating revenue), Pay TV revenues (7.7% of total operating revenue) and other services (13.2% of total operating revenue).
Other services include revenues from selling handsets and other equipment, as well as other miscellaneous revenue.

Revenues from wireless
and fixed voice services primarily include monthly subscription charges, airtime charges, charges for local and long-distance calls, and interconnection charges billed to other service providers for calls completed on our network. Revenues from
monthly subscription charges are driven mainly by the number of subscribers and the pricing of subscription packages. The primary driver of usage charges (airtime and interconnection charges) is traffic, which, in turn, is driven by the number of
customers and by their average usage. Postpaid wireless customers generally have an allotment of airtime each month for which they are not required to pay usage charges.

Revenues from wireless and fixed data services primarily include revenues from value-added services, corporate networks, data services and
internet access service. Revenues from corporate networks mainly consist of revenues from installing and leasing dedicated private lines, revenues from VPN services and revenues from the sale of value-added services to these customers.

Pay TV revenue consists primarily of subscription charges, charges for additional programming and advertising revenue.

Other services include sales revenues from selling handsets and other equipment and revenues from other businesses, such as yellow pages,
call-center services and publishing. Most of our new subscribers purchase a handset, and although we also sell new handsets to existing customers, changes in sales revenues are driven primarily by the number of new customers. The pricing of handsets
is not geared primarily towards making a profit from handset sales because it also takes into account the service revenues that are expected to result when the handset is used.

Revenues are recognized at the time services are provided. Billed revenues for service not yet rendered are recognized as deferred revenues.
Revenues from sales of prepaid services are deferred and recognized as airtime is used or when it expires, and they are included under mobile voice services.

Seasonality of our Business

Our business is subject to a certain degree of seasonality, characterized by a higher number of new customers during the fourth quarter of each
year. We believe this seasonality is mainly driven by the Christmas shopping season. Revenue also tends to decrease during the months of August and September, when family expenses shift towards school supplies and child care.

Mexican Tax Reform

In 2013, Mexico adopted a major package of tax reform measures that changed the tax regime applicable to us and our Mexican subsidiaries
beginning January 1, 2014. The changes applicable to us are extensive, and in some respects they may require us to pay more taxes than under prior law. The most significant impact is related to certain payments made to our employees that will
no longer be deductible for tax purposes, and will result in additional taxes that we estimate at approximately Ps.1.3 billion pesos for 2014. Although we are still evaluating the effects of the reforms, we do not currently expect the overall impact
of the tax reform on our financial performance to be material.

Use of Certain Operating Measures

In analyzing our financial performance, we use certain operating measures that are not included in our financial statements. These measures may
not be comparable with similarly titled measures and disclosures by other companies. The principal such measures are:

ARPUaverage revenues per user. This measure analyzes revenues from wireless data and voice services. We calculate ARPU for a given
period by dividing service revenues for such period on a local-currency basis by the simple average number of wireless subscribers for such period. The result is then presented in Mexican pesos, and comparability from one year to the next is
therefore affected by changes in exchange rates. The figure includes both prepaid and postpaid customers.

MOUsaverage
minutes of use per user. This measure analyzes usage of wireless services. We calculate MOUs by dividing total wireless traffic in a given period by the simple average number of wireless subscribers for such period.

ChurnThis measure analyzes the rate at which customers disconnect from our services (wireless, fixed or Pay TV). We calculate
churn rate as the total number of customer disconnections for a period divided by total subscribers at the beginning of such period. For wireless customers, postpaid subscribers are considered disconnected at the expiration of their contracts or
earlier if they voluntarily discontinue service or following a specified period after they become delinquent, and prepaid customers are considered disconnected following a specified period after they cease using our service, so long as they have not
activated a calling card or received traffic.

Market shareWe calculate our subscriber market share by dividing our own
subscriber figures into the total market subscriber figures periodically reported by the regulatory authorities in the markets in which we operate. We understand that these regulatory authorities compile total market subscriber figures based on
subscriber figures provided to them by market participants, and we do not independently verify these figures.

General Trends Affecting Operating
Results

Our results of operations in 2013 reflected several continuing long-term trends including:



| |  |  | intense competition, with growing subscriber acquisition costs and generally declining customer prices;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | growing demand for data services over both fixed and wireless networks;
| | - |  | -----------------------------------------------------------------------



| |  |  | declining demand for fixed voice services;
| | - |  | ------------------------------------------



| |  |  | declining interconnection rates; and
| | - |  | ------------------------------------



| |  |  | growing operating costs reflecting, among other things, higher cost of content for Pay TV and data services, costs of providing customer care, and costs of operating ever larger and more complex networks.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These trends are broadly characteristic of our businesses in all regions in recent years, and they have affected comparable
telecommunications providers as well. In addition, our Pay TV businesses have also continued to grow in all the regions where we provide Pay TV services.

Several other significant factors affected 2013 performance. In particular, our revenues from wireless voice services were adversely affected
by weak economic conditions in Mexico. In addition, the contribution of our Brazilian businesses to our operating results was adversely affected by the depreciation of the Brazilian currency against the Mexican peso. Exchange-rate movements also
affected our reported financing costs, as they do every year.

Operating revenues increased by 1.4% in 2013. At constant exchange rates, total operating revenues for 2013 increased by 7.9% over 2012. The
principal factors in the increase included increases in revenues from our Pay TV and mobile and fixed data services, slightly offset by a decrease in revenues from our fixed-line voice operations.

Mobile VoiceMobile voice revenues decreased by 7.7% in 2013. At constant exchange rates, mobile voice revenues for 2013 decreased
by 1.7% from 2012. The principal factor in the decrease was lower revenues from mobile voice services, principally in Mexico, Brazil and Colombia.

Fixed VoiceFixed voice revenues decreased by 9.7% in 2013. At constant exchange rates, total fixed voice revenues for 2013
decreased by 4.5% from 2012. The principal factors in the decrease were increased penetration of wireless technology, a decrease in long-distance traffic and lower interconnection rates, principally in Mexico, Brazil and Colombia.

Mobile DataMobile data revenues increased by 17.0% in 2013. At constant exchange rates, mobile data revenues for 2013 increased
by 23.4% from 2012. The principal factors in the increase were increased use of services such as media and content downloading, web browsing and machine-to-machine services as well as content downloading on handsets, tablets and notebooks.

Fixed DataFixed data revenues increased by 1.7% in 2013. At constant exchange rates, fixed data revenues for 2013 increased by
8.8% over 2012. The principal factors in the increase were residential broadband services growth, including growth of corporate data services such as cloud, dedicated lines and leasing.

Pay TVPay TV revenues increased by 7.6% in 2013. At constant exchange rates, total Pay TV revenues for 2013 increased by 21.0%.
The principal factors in the increase were increases in the use of our services as a result of the introduction of new plans and channel packages, particularly in Brazil, and subscriber growth in our operations in Brazil, Colombia, Peru, the
Dominican Republic and Ecuador.

Other ServicesRevenues from other services increased by 18.5% in 2013. At constant exchange
rates, revenues from other services for 2013 increased by 23.0% over 2012. The increase primarily reflects the sale of smartphones.

Operating Costs and Expenses

Cost of sales and servicesCost of sales and services increased by 5.0% in 2013, representing 45.6% of operating revenues in 2013,
compared to 44.0% of operating revenues in 2012. At constant exchange rates, cost of sales and services increased by 11.9% over 2012.

Cost of sales was Ps.122.0 billion in 2013 and Ps.110.5 billion in 2012 and primarily reflects the cost of handsets, accessories and
computers sold to customers. Costs of handsets, accessories and computers increased by 10.4% in 2013. This increase primarily reflects the purchase of increasing quantities of smartphones for sale to customers in all countries in which we operate,
which increased the subsidies we provide in order to acquire and retain subscribers.

Cost of services was Ps.236.3 billion in 2013 and
Ps.230.7 billion in 2012. Cost of services increased 2.5% in 2013. At constant exchange rates, cost of services for 2013 increased by 10.2% over 2012. This increase was principally due to growth of our network, including the deployment of 4G and LTE
networks, and increased customers throughout our businesses, as well as higher concession fees.

Commercial, administrative and generalCommercial, administrative and general
expenses increased by 1.0% in 2013, representing 21.3% of operating revenues in 2013 and 21.4% in 2012. At constant exchange rates, commercial, administrative and general expenses for 2013 increased by 8.1% over 2012. The increase in commercial,
administrative and general expenses in 2013 principally reflects subscriber acquisition costs in the wireless and Pay TV businesses, including those related to advertising campaigns in Brazil, Mexico and Colombia; higher customer-service costs
related to increases in the number of physical and telephone customer-service centers, to permit us to provide better customer care and quality of service and increased seasonal promotions; and telemarketing costs, such as temporary hiring of
employees and production of marketing materials, which received less supplier support than in the prior year.

Telcel and Telmex, like
other Mexican companies, are required by law to pay their employees, in addition to their agreed compensation and benefits, profit sharing in an aggregate amount equal to 10.0% of each entitys taxable income. Our subsidiaries in Ecuador and
Peru are also required to pay employee profit sharing at a rate of 15.0% and 10.0%, respectively, of taxable income. We account for these amounts under commercial, administrative and general expenses.

Depreciation and amortizationDepreciation and amortization decreased by 2.0% or Ps.2.0 billion in 2013. At constant exchange
rates, depreciation and amortization for 2013 increased by 5.3% over 2012, principally as a result of capital expenditures made in recent years. As a percentage of revenues, depreciation and amortization decreased from 13.4% in 2012 to 12.9% in
2013.

Operating Income

Operating income decreased by 4.3% in 2013. Operating margin (operating income as a percentage of operating revenues) was 19.6% in 2013 and
20.8% in 2012. The decrease in our operating margin in 2013 is due principally to higher costs for subscriber acquisition, network maintenance and customer service, as well as to the growth of lower margin businesses such as Pay TV and TracFone.

Non-Operating Items

Interest incomeInterest income increased by 8.1% in 2013. The total increase of Ps.0.5 billion in interest income is principally
due to higher cash balances.

Interest expenseInterest expense increased by 21.8% in 2013. The total increase of Ps.5.4
billion in interest expense is principally due to a higher average level of indebtedness.

Foreign exchange gain (loss),
netForeign exchange gain (loss), net represented a loss of Ps.19.6 billion in 2013, compared to a gain of Ps.7.4 billion in 2012. The net foreign exchange loss was primarily attributable to the appreciation of currencies in which our
indebtedness is denominated, particularly the euro and the U.S. dollar, as well as the effect on intercompany debt of the depreciation of the Brazilian real against the peso.

Valuation of derivatives and other financial items, netThe net change in valuation of derivatives and other financial items
represented a loss of Ps.5.2 billion in 2013, compared to a loss of Ps.12.5 billion in 2012. The loss is principally due to other financial expenses including commissions on financial services and interest cost of labor obligations. See Note 16(d)
to our audited consolidated financial statements included in this annual report.

Equity interest in net income of associated
companiesOur share of the net income of associated companies accounted for under the equity method was of Ps.0.04 billion in 2013 and Ps.0.8 billion in 2012. Our results from equity method investees for 2013 primarily reflect our interests
in KPN and Telekom Austria, which were acquired in 2012 and 2013.

Income TaxOur effective rates of provisions for corporate income tax as a percentage
of pretax income were 28.8% in 2013 and 33.4% in 2012. Our effective tax rate differs from the Mexican statutory rate of 30%, and decreased in 2013, primarily because of losses from the sale and restructuring of financial assets. See note 20 to our
consolidated financial statements.

Net Income

We had net income of Ps.75.0 billion in 2013 and Ps.91.6 billion in 2012. The decrease in net income in 2013 principally reflects higher
financing costs as a result of foreign exchange losses.

Consolidated Results of Operations for 2012 and 2011

Investment in Net Serviços

As of December 31, 2013, we owned, directly and indirectly through our Brazilian subsidiaries, 92.2% of the total equity of Net
Serviços, which provides Pay TV services in Brazil. We began consolidating Net Serviços from January 1, 2012, and, accordingly, the data presented in this annual report consolidate the results of Net Serviços as of and for
the years ended December 31, 2012 and 2013. Prior to January 1, 2012, we accounted for Net Serviços using the equity method. The consolidation of Net Serviços affects the comparability of our results for 2012 to our results
for 2011.

Operating Revenues

Operating revenues increased by 12.3% in 2012. At constant exchange rates and excluding the effects of the consolidation of Net
Serviços, total operating revenues for 2012 increased by 6.3% over 2011. The principal factors in the increase included increases in revenues from our Pay TV, wireless voice, and wireless and fixed data services, slightly offset by a decrease
in revenues from our fixed-line voice operations.

Mobile VoiceMobile voice revenues increased by 1.8% in 2012. At constant
exchange rates, mobile voice revenues for 2012 increased by 1.1% over 2011. The principal factors in the increase were an increase in traffic and the introduction of plans with more monthly airtime, partially offset by reductions in interconnection
rates charged to other telecommunications providers and reductions in rates charged to customers, principally in Mexico and Brazil.

Fixed VoiceFixed voice revenues decreased by 11.1% in 2012. At constant exchange rates and excluding the effects of the
consolidation of Net Serviços, total fixed voice revenues for 2012 decreased by 8.1% over 2011. The principal factors in the decrease were a decrease in long-distance traffic and lower interconnection rates, principally in Mexico and Brazil.

Mobile DataMobile data revenues increased by 33.5% in 2012. At constant exchange rates, mobile data revenues for 2012
increased by 32.9% from 2011. The principal factors in the increase were increased use of services such as SMS messaging, web browsing and machine-to-machine services, as well as content downloading on handsets, tablets and notebooks.

Fixed DataFixed data revenues increased by 16.1% in 2012. At constant exchange rates and excluding the effects of the
consolidation of Net Serviços, fixed data revenues for 2012 increased by 4.7% over 2011. The principal factors in the increase were residential subscriber and broadband services growth, including growth of corporate data services.

Pay TVPay TV revenues more than tripled in 2012 primarily because of the consolidation of Net Serviços. At constant
exchange rates and excluding the effects of the consolidation of Net Serviços, total Pay TV revenues for 2012 increased by 37.2% over 2011, principally due to an increase in the use of our services as a result of the introduction of new
plans, particularly in Brazil, and subscriber growth in our operations in Brazil, Colombia, Peru, the Dominican Republic and Ecuador.

Other ServicesRevenues from other services increased by 12.8% in 2012. At constant
exchange rates and excluding the effects of the consolidation of Net Serviços, revenues from other services for 2012 increased by 13.1% over 2011. The principal factor in the increase was the increase in the number of handsets, accessories
and computers sold as a result of the acquisition of new customers.

Operating Costs and Expenses

Cost of sales and servicesCost of sales and services increased by 17.8% in 2012, representing 44.0% of operating revenues in 2012,
compared to 42.0% of operating revenues in 2011. At constant exchange rates and excluding the effects resulting from the consolidation of Net Serviços, cost of sales and services increased by 11.5% over 2011.

Cost of sales was Ps.110.5 billion in 2012 and Ps.95.1 billion in 2011 and primarily represents the cost of handsets, accessories and
computers sold to customers. Costs of handsets, accessories and computers increased by 16.2% in 2012. This increase primarily reflects the effect of new plans offered to customers that include more expensive equipment, such as smartphones, which
requires larger subsidies.

Cost of services was Ps.231.0 billion in 2012 and Ps.195.0 billion in 2011. The 29.8% increase in 2012 was
principally due to the consolidation of Net Serviços commencing in January 2012, increased content charges as a result of the growth in our Pay TV business, increased costs to support the growth in our mobile data business and higher royalty
payments, as well as higher network maintenance and expansion, real estate leasing, electricity and labor costs. At constant exchange rates and excluding the effects of the consolidation of Net Serviços, cost of services for 2012 increased by
9.8% over 2011.

Commercial, administrative and generalCommercial, administrative and general expenses increased by 13.8% in
2012, representing 21.4% of operating revenues in 2012 and 21.1% in 2011. At constant exchange rates and excluding the effects resulting from the consolidation of Net Serviços, commercial, administrative and general expenses for 2012
increased by 5.6% over 2011. The increase in commercial, administrative and general expenses in 2012 principally reflects higher advertising and labor costs; subscriber acquisition costs in the wireless and Pay TV businesses, including those related
to advertising campaigns in Brazil, Mexico and Colombia; higher customer-service costs related to increases in the number of physical and telephone customer-service centers to permit us to provide better customer care and quality of service and
increased seasonal promotions; and telemarketing costs, such as temporary hiring of employees and production of marketing materials, which received less supplier support than in the prior year.

Telcel and Telmex, like other Mexican companies, are required by law to pay their employees, in addition to their agreed compensation and
benefits, profit sharing in an aggregate amount equal to 10.0% of each entitys taxable income. Our subsidiaries in Ecuador and Peru are also required to pay employee profit sharing at a rate of 15.0% and 10.0%, respectively, of taxable income.
We account for these amounts under commercial, administrative and general expenses.

Depreciation and
amortizationDepreciation and amortization increased by 10.2% or Ps.9.6 billion in 2012. At constant exchange rates and excluding the effects resulting from the consolidation of Net Serviços, depreciation and amortization for 2012
increased by 6.6% over 2011. As a percentage of revenues, depreciation and amortization decreased from 13.6% in 2011 to 13.4% in 2012.

Operating Income

Operating income increased by 2.2% in 2012, principally reflecting the consolidation of Net Serviços. Operating margin (operating income
as a percentage of operating revenues) was 20.8% in 2012 and 22.8% in 2011. The decrease in our operating margin in 2012 is due principally to higher costs for subscriber acquisition, network maintenance and customer service, as well as to the
growth of lower margin businesses such as Pay TV and TracFone.

##### Table of Contents

Non-Operating Items

Interest incomeInterest income decreased by 15.7% in 2012. The total decrease of Ps.1.1 billion in interest income is principally
due to lower cash balances, as a result of the use of cash to purchase minority interests in subsidiaries and investments in associates.

Interest expenseInterest expense increased by 19.8% in 2012. The total increase of Ps.4.1 billion in interest expense is
principally due to a higher average level of indebtedness.

Foreign exchange gain (loss), netForeign exchange gain (loss),
net represented a gain of Ps.7.4 billion in 2012, compared to a loss of Ps.22.4 billion in 2011. The net foreign exchange gain was primarily attributable to the appreciation at year-end of approximately 7.0% of the Mexican peso against the U.S.
dollar, which is the currency in which the majority of our indebtedness is denominated.

Valuation of derivatives and other financial
items, netThe net change in valuation of derivatives and other financial items represented a loss of Ps.12.5 billion in 2012, compared to a gain of Ps.4.7 billion in 2011. The loss is principally due to the effects of exchange rate
movements on derivative financial instruments we use to hedge our exchange rate exposure and, in particular, to the appreciation of the Mexican peso against the U.S. dollar in 2012.

Equity interest in net income of associated companiesOur share of the net income of associated companies accounted for under the
equity method was of Ps.0.8 billion in 2012 and Ps.1.9 billion in 2011. Our results from equity method investees for 2012 primarily reflect our interests in KPN and Telekom Austria, which we acquired in 2012. Our results from equity method investees
in 2011 primarily reflect our interest in Net Serviços, which became a consolidated subsidiary in 2012.

Income TaxOur
effective rates of provisions for corporate income tax as a percentage of pretax income were 33.4% in 2012 and 31.1% in 2011. Our effective tax rate differs from the Mexican statutory rate of 30.0%, principally because (a) in Mexico, for tax
purposes we recognize a taxable gain attributable to the effects of inflation on our financial liabilities and (b) our operations outside Mexico are taxed separately in each jurisdiction, at varying rates. The increase in the effective tax rate
in 2012 was due to a higher level of taxable inflationary effects and to a higher share of taxable income at certain non-Mexican subsidiaries. See note 20 to our consolidated financial statements.

Net Income

We had
net income of Ps.91.6 billion in 2012 and Ps.88.2 billion in 2011. The increase in net income in 2012 principally reflects lower financing costs as a result of foreign exchange gains.

Segment Results of Operations

We discuss
below the operating results of each operating segment. Note 21 to our audited consolidated financial statements describes how we translate the financial statements of our non-Mexican subsidiaries. Exchange rate changes between the Mexican peso and
the currencies in which our subsidiaries do business affect our reported results in Mexican pesos and the comparability of reported results between periods.

Interperiod Segment Comparisons

The following discussion addresses the financial performance of each of our operating segments, first by comparing results for 2013 and 2012,
and then by comparing results for 2012 and 2011. In the period-to-period comparisons for each segment, we include percentage changes in operating revenues, percentage changes in operating income and operating margin (operating income as a percentage
of operating revenues), in each case calculated based on the segment financial information presented in Note 21 to our audited financial statements, which is prepared in accordance with IFRS. Each geographical segment includes all income, cost and
expense eliminations that occurred between subsidiaries within the geographical segment. The Mexico Wireless segment also includes corporate income, costs and expenses.

Comparisons in the following discussion are calculated using figures in Mexican pesos. We also include percentage changes in adjusted segment
operating revenues, percentage changes in adjusted segment operating income, and adjusted operating margin (adjusted operating income as a percentage of adjusted operating revenues). The adjustments eliminate (a) certain intersegment
transactions, (b) for our non-Mexican segments, effects of exchange rate changes, and (c) for the Mexican Wireless segment only, revenues and costs of group corporate activities and other businesses that are allocated to the Mexico
Wireless segment.

2013 Compared to 2012

Mexico Wireless

Segment
operating revenues increased by 5.2% in 2013. Adjusted revenues increased 3.9% in 2013. This increase was primarily driven by an increase in value-added services revenues. Wireless voice revenues decreased by 8.4% in 2013, reflecting primarily
larger discounts and promotions for prepaid customers and weaker economic conditions. Wireless data revenues increased by 12.5% in 2013, principally due to increased demand for value-added services.

In 2013, the number of prepaid wireless subscribers increased by 3.8%, and the number of postpaid wireless subscribers increased by 9.1%,
resulting in an increase in the total number of wireless subscribers in Mexico of 4.5% to approximately 73.5 million as of December 31, 2013, which represented a net addition of 3.1 million wireless subscribers.

Average MOUs per subscriber increased by 3.0% in 2013. ARPU decreased by 5.1% in 2013. During 2013, we lowered the price of some of our
services in Mexico through new commercial plans and promotions, which contributed to the increase in subscribers (primarily prepaid subscribers, who received double the airtime they

purchased under various promotional packages) and MOUs. Reductions in interconnection tariffs and a decline in long-distance traffic resulted in lower interconnection revenues in 2013. The
wireless churn rate for our Mexican Wireless operations was 3.7% during 2012 and 3.8% in 2013.

Segment operating income decreased by 3.9%
in 2013. Adjusted operating income decreased by 2.4% in 2013. Segment operating margin (operating income as a percentage of operating revenues) was 40.8% in 2013 and 44.6% in 2012. Adjusted operating margin for this segment was 43.7% in 2013 and
46.5% in 2012. The decrease in operating margin in 2013 was due principally to higher equipment costs (larger subsidies), as well as customer services, network maintenance and value-added services costs (including payments to content providers).

Mexico Fixed

Segment operating revenues decreased by 0.1% in 2013. This decrease was principally due to decreases in voice revenues, partially offset by an
increase in fixed data revenues. Fixed voice revenues decreased by 7.0% in 2013, reflecting significant reductions in local and long-distance prices and subscribers. Revenues from broadband and corporate network services increased by 3.7% in 2013,
principally due to the phasing out of introductory promotional packages from earlier periods, and an increase in the broadband subscriber base.

In 2013, the number of fixed voice RGUs in Mexico decreased by 4.8%, and the number of broadband RGUs in Mexico increased by 4.8%, resulting
in a decrease in total RGUs in Mexico of 1.2% to approximately 22.5 million as of December 31, 2013. In 2013, long-distance minutes increased by 5.2% and interconnection minutes increased by 7.4%, resulting in an increase in total minutes
in Mexico of 6.4%. The fixed voice churn rate increased slightly from 1.1% in 2012 to 1.4% in 2013. The broadband churn rate decreased slightly from 1.4% in 2012 to 1.2% in 2013.

Segment operating income decreased by 3.9% in 2013. Adjusted segment operating income decreased by 8.6%. Segment operating margin was 18.9% in
2013 and 19.7% in 2012. Adjusted operating margin for this segment was 19.1% in 2013 and 20.5% in 2012. The decrease in 2013 was due principally to higher broadband and fixed line maintenance and energy costs, which were necessary to increase
capacity, increases in our pension obligations to former employees and increased personnel costs as a consequence of an employee salary increase during 2013.

Segment operating
revenues decreased by 4.7% in 2013. Adjusted segment operating revenues increased by 8.1% in 2013. Wireless data revenues increased 19.2% in 2013 and fixed data revenues increased 11.4%, as a result of greater use of value-added services such as SMS
messaging and web browsing. Pay TV revenues increased by 21.9% in 2013 as a result of subscriber growth driven by new commercial packages offered by Embratel. Wireless and fixed voice revenues decreased by 4.8% and 3.2%, respectively, in 2013.
Revenues decreased the most for wireless and fixed long-distance services, which primarily reflects promotions implemented during 2013.

In 2013, the number of prepaid wireless subscribers increased by 4.2%, and the number of postpaid wireless subscribers increased by 9.6%,
resulting in an increase in the total number of wireless subscribers in our Brazil segment of 5.3% to approximately 68.7 million as of December 31, 2013. In 2013, the number of fixed voice RGUs increased by 8.8%, the number of broadband

and 6.0% in 2012. Adjusted segment operating margin was 4.2% in 2013 and 5.1% in 2012. Adjusted segment operating income and operating margin in 2013 were affected by subscriber acquisition costs, higher costs for customer service, call centers and
energy, and advertising, higher rent and marketing costs associated with the integration of our various Brazilian brands.

Colombia

Segment operating revenues increased 1.1% in 2013. Adjusted operating revenues increased by 8.3%. Fixed and wireless data services
increased by 17.2% and 20.0%, respectively, in 2013, as a result of new promotional packages focused on SMS texting and web browsing. Fixed voice revenues increased by 18.9% and wireless voice revenues decreased 2.1% in 2013. Pay TV revenues
increased by 9.4% in 2013.

Average MOUs per subscriber decreased by 4.3% in 2013. ARPU decreased by 0.7% in 2013. The decreases in
average MOUs and ARPU in 2013 reflected primarily a decrease in traffic, partially resulting from fundamental changes in our commercial conditions, linked to regulatory measures. Mobile data use did not increase sufficiently to offset these
declines.

Segment operating income decreased by 6.0% in 2013. Adjusted segment operating income increased by 4.6%. Segment operating
margin was 28.8% in 2013 and 30.9% in 2012. Adjusted segment operating margin was 31.7% in 2013 and 32.9% in 2012. The decrease in segment operating margin in 2013 was principally due to higher subscriber acquisition costs, primarily as a result of
handset subsidies offered to new customers.

Southern ConeArgentina, Chile, Paraguay and Uruguay

Segment operating revenues decreased by 0.8% in 2013, reflecting a decrease of 2.6% in Argentina, Paraguay and Uruguay and an increase of 4.0%
in Chile. Adjusted segment operating revenues increased by 15.9%, reflecting an adjusted operating revenue increase of 20.8% in Argentina, Paraguay and Uruguay and 9.2% in Chile. The decrease in segment operating revenue in Argentina, Paraguay and
Uruguay is primarily related to the devaluation of the Argentine peso. The increase in segment operating revenue in Chile was driven primarily by higher usage of all services, principally data services. For this segment, we analyze results in
Argentina, Paraguay and Uruguay in terms of the Argentine peso because Argentina accounts for the major portion of the operations in these three countries.

Average MOUs per subscriber decreased by 1.3% in 2013, primarily due to the phasing out of promotional packages from earlier periods for both
prepaid and postpaid services. ARPU decreased by 9.6% in Argentina, Paraguay and Uruguay and decreased by 3.6% in Chile. ARPU was negatively affected by changes in exchange rates, and at constant exchange rates would have been positive for

CaribbeanDominican Republic and Puerto Rico

Segment operating revenues decreased by 7.0% in 2013. Adjusted segment operating revenues decreased by 4.8%. We analyze segment results in U.S.
dollars because it is the functional currency in our operations in Puerto Rico and the currency in the Dominican Republic is relatively stable against the U.S. dollar.

Average MOUs per subscriber decreased by 7.3% in 2013, primarily due to reduced usage of voice services. ARPU decreased by 8.5% in 2013. This
decrease in ARPU was primarily attributable to declining prices and average voice usage, and a more competitive market for voice services.

Segment operating income increased by 55.3% in 2013. Adjusted segment operating income increased by 43.5% in 2013. Segment operating margin
was 17.6% in 2013 and 10.5% in 2012. Adjusted segment operating margin was 17.2% in 2013 and 11.4% in 2012. The increases in adjusted segment operating income and operating margin in 2013 were driven primarily by a reduction in labor obligation
costs in Puerto Rico.

2012 Compared to 2011

Mexico Wireless

Segment
operating revenues increased by 8.6% in 2012. Adjusted revenues increased 8.4% in 2012. This increase was primarily driven by an increase in data revenues. Wireless voice revenues decreased by 2.0% in 2012, reflecting primarily larger discounts and
promotions for prepaid customers. Wireless data revenues increased by 30.4% in 2012, principally due to increased demand for these services.

In 2012, the number of prepaid wireless subscribers increased by 6.1%, and the number of postpaid wireless subscribers increased by 15.4%,
resulting in an increase in the total number of wireless subscribers in Mexico of 7.1% to approximately 70.4 million as of December 31, 2012, which represented a net addition of 4.7 million wireless subscribers.

Average MOUs per subscriber increased by 18.8% in 2012. ARPU increased by 6.0% in 2012. During 2012, we lowered the price of some of our
services in Mexico through new commercial plans and promotions, which contributed to the increase in subscribers (primarily prepaid subscribers), MOUs and ARPU. Reductions in interconnection tariffs and a decline in long-distance traffic resulted in
lower interconnection revenues in 2012. The wireless churn rate for our Mexican Wireless operations remained at 3.7% during 2012, the same rate as in 2011.

Segment operating income increased by 7.8% in 2012. Adjusted operating income increased by 5.2% in 2012. Segment operating margin (operating
income as a percentage of operating revenues) was 44.6% in 2012 and 44.9% in 2011. Adjusted operating margin for this segment was 46.3% in 2012 and 47.7% in 2011. The decrease in operating margin in 2012 is due principally to higher equipment costs
(larger subsidies), network maintenance, value-added services costs (payments to content providers), leases and spectrum fees.

Mexico
Fixed

Segment operating revenues decreased by 5.5% in 2012. This decrease is principally due to decreases in voice revenues, partially
offset by an increase in data revenues. Fixed voice revenues decreased by 9.3% in 2012, reflecting significant reductions in local and long-distance traffic mainly as a result of new promotions on calls to wireless devices. Revenues from broadband
and corporate network services decreased by 2.2% in 2012, principally due to the loss of corporate and residential subscribers, and special promotions offered to our subscribers.

In 2012, the number of fixed voice RGUs in Mexico decreased by 4.0%, and the number of broadband RGUs in Mexico increased by 6.9%, resulting
in a decrease in total RGUs in Mexico of 0.2% to approximately 22.7 million as of December 31, 2012. In 2012, long-distance minutes increased by 21.4% and interconnection

minutes increased by 1.4%, resulting in an increase in total minutes in Mexico of 9.8%. The fixed voice churn rate decreased slightly from 1.2% in 2011 to 1.1% in 2012. The broadband churn rate
was 1.4% during 2012, the same rate as in 2011.

Segment operating income decreased by 22.7% in 2012. Adjusted segment operating income
decreased by 27.9%. Segment operating margin was 19.7% in 2012 and 24.0% in 2011. Adjusted operating margin for this segment was 18.9% in 2012 and 24.8% in 2011. The decrease in 2012 is due principally to higher broadband maintenance and energy
costs, increases in our pension obligations to former employees and increased personnel costs as a consequence of an employee salary increase during 2012.

Brazil

In January 2012,
we acquired control of a majority of the voting equity of Net Serviços. We began consolidating Net Serviços from January 1, 2012. Prior to January 1, 2012, we accounted for Net Serviços using the equity method. The
consolidation of Net Serviços affects the comparability of our results for 2012 to our results 2011 and 2010.

Including the
effects of the Net Serviços consolidation, segment operating revenues increased by 18.1% in 2012. Adjusted operating revenues increased by 4.7% in 2012. At constant exchange rates and excluding the effects of the consolidation of Net
Serviços, segment operating revenues for 2012 increased by 1.9% over 2011. This increase is due principally to increases in wireless data and Pay TV revenues. Wireless data revenues increased 19.1% in 2012 and fixed data revenues increased
3.5%, as a result of greater use of value-added services such as SMS messaging and web browsing. Pay TV revenues increased by 60.9% in 2012 as a result of subscriber growth driven by new commercial packages of Embratel. Wireless and fixed voice
revenues decreased by 6.7% and 5.2% in 2012. Revenues decreased the most for wireless and fixed long-distance services, which primarily reflects promotions implemented during 2012.

In 2012, the number of prepaid wireless subscribers increased by 9.3%, and the number of postpaid wireless subscribers increased by 3.2%,

RGUs increased by 23.4% and the number of pay TV RGUs increased by 28.5%, resulting in an increase in total RGUs in our Brazil segment of 21.2% to approximately 28.6 million as of December 31, 2012.

Average MOUs per subscriber increased by 15.0% in 2012. The increase in average MOUs during 2012 reflects increased traffic, on net and from
other providers, in our network, which was partly due to new commercial plans and promotional packages. ARPU decreased by 20.7% in 2012. This decrease during 2012 reflects a decrease in monthly airtime and interconnection rates that was not offset
by increased data usage.

Segment operating income increased by 40.0% in 2012. Segment operating margin was 6.0% in 2012 and 5.1% in 2011.
Adjusted segment operating margin was 4.6% in 2012 and 5.9% in 2011. Adjusted segment operating income and operating margin in 2012 were affected by subscriber acquisition costs, higher costs for customer service, call centers and energy, higher
rent and marketing costs associated with the integration of our various Brazilian brands.

Colombia

Segment operating revenues increased 20.2% in 2012. Adjusted operating revenues increased by 10.9%. This increase reflected principally
increases in fixed and wireless data revenues and fixed voice. Fixed and wireless data services increased by 31.9% in 2012, as a result of new promotional packages focused on SMS texting and web browsing. Fixed and wireless voice revenues increased
by 4.9% in 2012. Pay TV revenues increased by 8.5% in 2012.

Central AmericaGuatemala, El Salvador, Honduras, Nicaragua, Panama and Costa Rica

Segment operating revenues increased 17.8% in 2012. Adjusted segment operating revenues increased by 9.7% in 2012. These increases
were driven primarily by increases in wireless data, broadband and pay TV services, offset by decreases in fixed voice services. For this purpose, we analyze segment results in U.S. dollars because it is the functional currency in our operations in
El Salvador (our headquarters for this segment) and Panama and the currencies in Costa Rica, Guatemala, Honduras and Nicaragua are relatively stable against the U.S. dollar.

Average MOUs per subscriber increased by 10.1% in 2012, primarily due to new commercial plans for voice and data services. ARPU increased by
6.8%. This increase was primarily attributable to increased usage of our services, and more specifically, of data services in Guatemala, El Salvador, Nicaragua and Honduras and of voice services in Honduras, partly offset by decreased usage of voice
services in Guatemala, El Salvador and Nicaragua.

Segment operating margin was (15.2)% in 2012 and (0.3)% in 2011. Adjusted segment
operating margin was (14.9)% in 2012 and 0.5% in 2011. Segment operating margin in 2012 was affected by higher depreciation, partially resulting from the depreciation of plant and equipment of Digicel Honduras, which we acquired in November 2011.

United States

Segment operating revenues increased by 32.8% in 2012. Adjusted segment operating revenues increased by 25.7% in 2012. This increase is due
principally to customer base increases, and the growth of the Straight Talk and SafeLink promotional plans, which continue to grow but not at the same pace as in 2011. Wireless data services increased by 77% during 2012 and now represent 34.5% of
service revenues. In 2012, the number of wireless subscribers, all of which are prepaid subscribers, increased by 13.3% to approximately 2.6 million as of December 31, 2012.

Average MOUs per subscriber increased by 20.9% in 2012. ARPU increased by 18.4% in 2012. The increase in average MOUs and ARPU is primarily

Liquidity and Capital Resources

Funding Requirements

We generate substantial cash flows from our operations. On a consolidated basis, operating activities provided Ps.187.8 billion in 2013
and Ps.206.6 billion in 2012. Our cash and cash equivalents amounted to Ps.48.2 billion at December 31, 2013 compared to Ps.45.5 billion at December 31, 2012. We believe our working capital is sufficient for our present requirements.
We use the cash that we generate from our operations and from borrowings primarily for the following purposes:



| |  |  | We make substantial capital expenditures to continue expanding and improving our networks in each country in which we operate. Our capital expenditures on plant, property and equipment and acquisition or renewal of
licenses were Ps.121.8 billion in 2013 and Ps.130.9 billion in 2012. The amount we spend on acquisitions and licenses varies significantly from year to year, depending on acquisition opportunities, concession renewal schedules and needs for more
spectrum. We have budgeted capital expenditures for 2014 to be approximately U.S.$8.3 billion (Ps.107.0 billion).
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In some years, we make substantial expenditures on acquisitions. In April 2013, KPN launched a rights offering to raise up to 3 billion, and we participated in proportion to our investment at the time.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We must pay interest on our indebtedness and repay principal when due. As of December 31, 2013, we had Ps.25.8 billion of principal and amortization due in 2014.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We pay regular dividends. We paid Ps.15.7 billion in dividends in 2013 and Ps.15.4 billion in 2012. Our shareholders have approved the payment of a Ps.0.24 dividend per share in two installments in 2014.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We regularly repurchase our own shares. We spent (including commissions and value-added taxes) Ps.70.7 billion repurchasing our own shares in the open market in 2013 and Ps.17.8 billion in 2012. Our shareholders have
authorized additional repurchases, and as of March 31, 2014, we have spent Ps.12.3 billion repurchasing our shares in the open market in 2014, but whether we will continue to do so will depend on our operating cash flow and on various other
considerations, including market prices and our other capital requirements.

We continue to seek investment opportunities in telecommunications and related companies
worldwide, including in markets where we are already present, and we often have several possible acquisitions under consideration. We can give no assurance as to the extent, timing or cost of such investments. We may pursue opportunities in Latin
America or in other areas in the world. Some of the assets that we acquire may require significant funding for capital expenditures.

Borrowings

In
addition to cash flows generated from operations, we rely on a combination of borrowings in the Mexican and international capital markets, borrowings from international banks and equipment financing. As of December 31, 2013, our total
consolidated indebtedness was Ps.490.3 billion, compared to Ps.417.7 billion as of December 31, 2012. Our net debt (total debt minus cash and cash equivalents) at December 31, 2013 was Ps.442.2 billion, an increase of 19.0% as
compared to December 31, 2012.

Without taking into account the effects of derivative financial instruments that we use to manage our
interest rate and currency risk, approximately 84.2% of our indebtedness at December 31, 2013 was denominated in currencies other than Mexican pesos (approximately 51.9% of such non-Mexican peso debt in U.S. dollars and 48.1% in other
currencies), and approximately 5.9% of our consolidated debt obligations bore interest at floating rates. After the effects of derivative transactions, approximately 14.0% of our total debt as of December 31, 2013 was denominated in U.S.
dollars and we had no exposure to floating rates.

The weighted average cost of all our third-party debt at December 31, 2013
(excluding commissions and reimbursement of certain lenders for Mexican taxes withheld) was approximately 4.8% per annum.

Our major
categories of indebtedness at December 31, 2013 are summarized in the table below.

Additional information about certain categories of our indebtedness is provided below:



| |  |  | Mexican peso-denominated international notes. Our 9.0% senior notes due January 2016 and our 8.46% senior notes due 2036 are denominated in Mexican pesos, but all amounts in respect of the notes are payable in
U.S. dollars, unless a holder of notes elects to receive payment in Mexican pesos in accordance with certain specified procedures.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Mexican peso-denominated domestic notes. Our domestic senior notes (certificados bursátiles) sold in the Mexican capital markets have varying maturities, ranging from 2014 through 2037. Some bear
interest at fixed rates, and others at variable rates based on TIIE (a Mexican interbank rate).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Global peso note program. Since November 2012, we have issued peso-denominated notes that can be distributed and traded on a seamless basis in Mexico and internationally. The notes are registered with both
the U.S. Securities and Exchange Commission and the Mexican Banking and Securities Commission. We sold Ps.15 billion of notes under the program in November 2012 and a further Ps.7.5 billion in March 2013. We intend to use the program to raise a
total of Ps.100 billion over five years to increase the share of Mexican pesos in our overall funding.

| |  |  | Dollar-denominated international notes. We have outstanding debt securities in the international markets denominated in U.S. dollars. In September 2013, we issued U.S. dollar denominated notes that bear interest
at a variable rate equal to three-month LIBOR plus a spread. This series matures in 2016.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Hybrid Notes. In September 2013, we issued three series of Capital Securities maturing in 2073: two series denominated in euros and totaling 1,450 million, and one series denominated in pounds
sterling in the amount of £550 million. The Capital Securities are deeply subordinated, and when they were issued the principal rating agencies stated that they would treat only half of the principal amount as indebtedness for purposes of
evaluating our leverage (an analysis referred to as 50% equity credit). The Capital Securities are subject to redemption at our option at varying dates beginning in 2018 or 2023 for the euro-denominated series and beginning in 2020 for the
sterling-denominated series.

| |  |  | Colombian peso-denominated notes. Comcel has issued notes in the Colombian capital markets denominated in Colombian pesos. The notes outstanding as of December 31, 2013 bear interest at 7.59%, and
matures in 2016.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Bank loans. At December 31, 2013, we had approximately Ps.5,095 million outstanding under a number of bank facilities bearing interest at fixed rates. In May 2011, we entered into two revolving
syndicated facilitiesone for U.S.$2 billion and one for the Euro equivalent of U.S.$2 billion. The Euro equivalent revolving syndicated facility was amended in July 2013 to increase the amount available to U.S.$2.1 billion. Loans under the
facilities bear interest at variable rates based on LIBOR and EURIBOR. The syndicated facilities include covenants that limit our ability to incur secured debt, to effect a merger as a result of which the surviving entity would not be América
Móvil or Telcel, to sell substantially all of our assets or to sell control of Telcel. The facilities do not allow us to impose any restrictions on the ability of Telcel to pay dividends or make distributions to us. In addition, the bank
facilities require us to maintain a consolidated ratio of debt to EBITDA not greater than 4.0 to 1.0 and a consolidated ratio of EBITDA to interest expense not less than 2.5 to 1.0. As of the date of this annual report, we are in compliance with
these covenants.

| |  |  | Equipment financing facilities with support from export development agencies. We have a number of equipment financing facilities, under which export development agencies provide support for financing to
purchase exports from their respective countries. These facilities are medium- to long-term, with periodic amortization. Some facilities bear interest at a fixed rate while others bear interest at a spread over LIBOR. They are extended to us or to
operating subsidiaries, in some cases with the guarantee of Telcel.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Some of the public securities issued by América
Móvil in international and Mexican capital markets, and amounts due under our syndicated loan facility and export credit facilities, are guaranteed by Telcel. As of December 31, 2013, we had, on an unconsolidated basis, unsecured and
unsubordinated indebtedness of approximately Ps. 439.8 billion (U.S.$33.6 billion) excluding guarantees of subsidiaries indebtedness. As of December 31, 2013, our subsidiaries had indebtedness (excluding guarantees of indebtedness of us
and our other subsidiaries) of approximately Ps. 50.6 billion (U.S.$3.9 billion).

Risk Management

We regularly assess our interest rate and currency exchange exposures in order to determine how to manage the risk associated with these
exposures. We have indebtedness denominated in currencies, principally the U.S. dollar, other than the currency of our operating environment. We use cross-currency swaps and forwards to adjust the resulting exchange rate exposures. We do not use
derivatives to hedge the exchange rate exposures that arise from having operations in different countries.

We also use interest rate
swaps from time to time to adjust our exposure to variable interest rates or to reduce our costs of financing. Our practices vary from time to time depending on our judgment of the level of

risk, expectations as to exchange or interest rate movements and the costs of using derivative financial instruments. We may stop using derivative financial instruments or modify our practices at
any time.

As of December 31, 2013, we had derivatives positions with an aggregate net fair value of Ps.5.1 billion, which are
described in Note 11 to our audited consolidated financial statements.

Off-Balance Sheet Arrangements

As of December 31, 2013, we had no off-balance sheet arrangements that require disclosure under applicable SEC regulations.

Use of Estimates in Certain Accounting Policies

In preparing our financial statements, we make estimates concerning a variety of matters. Some of these matters are highly uncertain, and our
estimates involve judgments we make based on the information available to us. In the discussion below, we have identified several of these matters for which our financial presentation would be materially affected if either (1) we used different
estimates that we could reasonably have used or (2) in the future we change our estimates in response to changes that are reasonably likely to occur.

The discussion addresses only those estimates that we consider most important based on the degree of uncertainty and the likelihood of a
material impact if we used a different estimate. There are many other areas in which we use estimates about uncertain matters, but the reasonably likely effect of changed or different estimates is not material to our financial presentation.

Fair Value of Financial Assets and Liabilities

We have substantial financial assets and liabilities that we recognize at their fair value, which is an estimate of the amount at which the
instrument could be exchanged in a current transaction between willing parties. The methodologies and assumptions we use to estimate an instruments fair value depend on the type of instrument and include (i) recognizing cash and cash
equivalents and trade receivables and trade payables and other current liabilities at close to their carrying amount, (ii) recognizing quoted instruments at their price quotations on the reporting date, (iii) recognizing unquoted
instruments, such as loans from banks and obligations under financial leases, by discounting future cash flows using rates for similar instruments and (iv) applying various valuation techniques, such as present value calculations, to derivative
instruments. Using different methodologies or assumptions to estimate the fair value of our financial assets and liabilities could materially impact our reported financial results.

Estimated useful lives of plant, property and equipment

We estimate the useful lives of particular classes of plant, property and equipment in order to determine the amount of depreciation expense to
be recorded in each period. Depreciation expense is a significant element of our costs and expenses, amounting in 2013 to Ps.94.9 billion, or 15.0% of our operating costs and expenses. See Note 8 to our consolidated financial statements.

We currently depreciate most of our telephone plant and equipment based on an estimated useful life determined upon the expected particular
conditions of operations and maintenance in each of the countries in which we operate. The estimates are based on our historical experience with similar assets, anticipated technological changes and other factors, taking into account the practices
of other telecommunications companies. We review estimated useful lives each year to determine whether they should be changed, and at times, we have changed them for particular classes of assets. We may shorten the estimated useful life of an asset
class in response to technological changes, changes in the market or other developments. This results in increased depreciation expense.

Impairment of Long-Lived Assets

We have large amounts of long-lived assets, including property, plant and equipment, intangible assets, investments in associates and goodwill,
on our balance sheet. Under IFRS, we are required to test long-lived assets for impairment when circumstances indicate a potential impairment or, in some cases, at least on an annual basis. The impairment analysis for long-lived assets requires us
to estimate the recovery value of the asset, which is the greater of its fair value (minus any disposal costs) and its value in use. To estimate the fair value of a long-lived asset, we typically take into account recent market transactions or, if
no such transactions can be identified, we use a valuation model that requires the making of certain assumptions and estimates. Similarly, to estimate the value in use of long-lived assets, we typically make various assumptions about the future
prospects for the business to which the asset relates, consider market factors specific to that business and estimate discounted future cash flows to be generated by that business. Based on this impairment analysis, including all assumptions and
estimates related thereto, as well as guidance provided by IFRS relating to the impairment of long-lived assets, we determine whether we need to take an impairment charge to reduce the carrying value of the asset as stated on our balance sheet.
Assumptions and estimates about future values and remaining useful lives are complex and often subjective. They can be affected by a variety of factors, including external factors, such as industry and economic trends, and internal factors, such as
changes in our business strategy and our internal forecasts. Different assumptions and estimates could materially impact our reported financial results. More conservative assumptions of the anticipated future benefits from these businesses could
result in impairment charges, which would decrease net income and result in lower asset values on our balance sheet. Conversely, less conservative assumptions could result in smaller or no impairment charges, higher net income and higher asset
values. See Note 2 l) to our audited consolidated financial statements.

Among the long-lived assets we test for impairment are our equity
investments in KPN and Telekom Austria. Under IFRS, an impairment is recognized as the difference between the carrying value of the investment and the greater of its fair value and its value in use. For each investment, the carrying value exceeded
fair value at December 31, 2012 and at December 31, 2013. In each case, we determined that we would recover the carrying value of the investment through its future value in use, so no impairment was recognized. See Note 10 to our audited
consolidated financial statements.

Deferred Taxes

We are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves the
jurisdiction-by-jurisdiction estimation of actual current tax exposure and the assessment of temporary differences resulting from the differing treatment of certain items, such as accruals and amortization, for tax and financial reporting purposes,
as well as net operating loss carry-forwards and other tax credits. These items result in deferred tax assets and liabilities, which are included in our consolidated balance sheets. We must assess in the course of our tax planning procedures the
fiscal year of the reversal of our deferred tax assets and liabilities, and if there will be future taxable profits in those periods to support the recognition of the deferred tax assets. Significant management judgment is required in determining
our provisions for income taxes, deferred tax assets and liabilities. The analysis is based on estimates of taxable income in the jurisdictions in which the group operates and the period over which the deferred tax assets and liabilities will be
recoverable or settled. If actual results differ from these estimates, or we adjust these estimates in future periods, our financial position and results of operations may be materially affected.

We record deferred tax assets based on the amount that we believe is more likely than not to be realized. In assessing the future realization
of deferred tax assets, we consider future taxable income and ongoing tax planning strategies. In the event that our estimates of projected future taxable income and benefits from tax planning strategies are lowered, or changes in current tax
regulations are enacted that would impose restrictions on the timing or extent of our ability to utilize the tax benefits of net operating loss carry-forwards in the future, an adjustment to the recorded amount of deferred tax assets would be made,
with a related charge to income.

Accruals

Accruals are recorded when, at the end of the period, we have a present obligation as a result of past events, whose settlement requires an
outflow of resources that is considered probable and can be measured reliably. This obligation may be legal or constructive, arising from, but not limited to, regulation, contracts, common practice or public commitments, which have created a valid
expectation for third parties that we will assume certain responsibilities. The amount recorded is the best estimation performed by our management in respect of the expenditure that will be required to settle the obligations, considering all the
information available at the date of our financial statements, including the opinion of external experts, such as legal advisors or consultants. Accruals are adjusted to account for changes in circumstances for ongoing matters and the establishment
of additional accruals for new matters.

If we are unable to reliably measure the obligation, no accrual is recorded and information is
then presented in the notes to our consolidated financial statements. Because of the inherent uncertainties in this estimation, actual expenditures may be different from the originally estimated amount recognized.

Labor Obligations

We recognize liabilities on our balance sheet and expenses in our income statement to reflect our obligations related to our post-retirement
seniority premiums, pension and retirement plans in the countries in which we operate and offer defined contribution and benefit pension plans. The amounts we recognize are determined on an actuarial basis that involves many estimates and accounts
for post-retirement and termination benefits in accordance with IFRS.

We use estimates in four specific areas that have a significant
effect on these amounts: (a) the rate of return we assume our labor obligation plans will achieve on their investments, (b) the rate of increase in salaries that we assume we will observe in future years, (c) the discount rates that
we use to calculate the present value of our future obligations and (d) the expected rate of inflation. The assumptions we have applied are identified in Note 12 to our audited consolidated financial statements. These estimates are
determined based on actuarial studies performed by independent experts using the projected unit-credit method. The latest actuarial computation was prepared as of December 31, 2013.

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts for estimated losses resulting from the failure of customers, distributors and cellular
operators to make required payments. We base these estimates on the individual conditions of each of the markets in which we operate that may impact the collectability of accounts. In particular, in making these estimates we take into account
(i) with respect to accounts with customers, the number of days since the calls were made, (ii) with respect to accounts with distributors, the number of days invoices are overdue and (iii) with respect to accounts with cellular
operators, both the number of days since the calls were made and any disputes with respect to such calls. The amount of loss, if any, that we actually experience with respect to these accounts may differ from the amount of the allowance maintained
in connection with them.

MANAGEMENT

Directors

Our Board of Directors has broad authority to manage our company. Our bylaws provide for the Board of Directors to consist of between
five and twenty-one directors and allow for the election of an equal number of alternate directors. Directors need not be shareholders. A majority of our directors and a majority of the alternate directors must be Mexican citizens and elected by
Mexican shareholders. A majority of the holders of the AA Shares and A Shares voting together elect a majority of the directors and alternate directors, provided that any holder or group of holders of at least 10% of the total AA Shares and A Shares
is entitled to name one director and an alternate director. Two directors and two alternate directors, if any, are elected by a majority vote of the holders of L Shares. Each alternate director may attend meetings of the Board of Directors and vote
in the absence of a corresponding director. Directors and alternate directors are elected or reelected at each annual general meeting of shareholders and each annual ordinary special meeting of holders of L Shares, and each serves until a successor
is elected and takes office. In accordance with the Mexican Securities Market Law (Ley del Mercado de Valores), the determination as to the independence of our directors is made by our shareholders, though the CNBV may challenge this
determination. Pursuant to our bylaws and the Mexican Securities Market Law, at least 25% of our directors must be independent. In order to have a quorum for a meeting of the Board of Directors, a majority of those present must be Mexican
nationals.

All of the current members of the Board of Directors, the Executive Committee, the Audit and Corporate Practices
Committee, and the Operations in Puerto Rico and the United States of America Committee were reelected, and the Corporate Secretary and the Corporate Pro-Secretary were reappointed at the annual general shareholders meeting held on
April 28, 2014, with fourteen directors elected by the AA Shares and A Shares voting together and two directors elected by the L Shares. One alternate director was reelected.

Our bylaws provide that the members of the Board of Directors are elected for a term of one year. Pursuant to Mexican law, members of the
Board continue in their positions after the expiration of their terms for up to an additional thirty-day period if new members are not elected. Furthermore, in certain circumstances provided under the Mexican Securities Law, the Board of Directors
may elect temporary directors who then may be elected or substituted at the shareholders meetings. The names and positions of the members of the Board elected and reelected at the annual general shareholders meeting held on
April 28, 2014, their year of birth, and information concerning their committee membership and principal business activities outside América Móvil are as follows:

third party (i) gives AT&TI the right to sell the same portion of its AA Shares to such third-party in connection with the sale of such AA Shares of the Family Trust and (ii) gives the Family Trust the right to require AT&TI to
sell the same portion of its AA Shares to such third party as the Family Trust is selling to such third party. These rights do not apply to the conversion of AA Shares to L Shares, as permitted by our bylaws, or the subsequent transfer of L Shares.
The agreement also gives AT&TI the right to nominate two candidates to our Board of Directors and to appoint one member to our Executive Committee.

As of March 31, 2014, 20.3% of the outstanding L Shares were represented by L Share ADSs, each representing the right to receive 20 L
Shares, and 99.3% of the L Share ADSs were held by 9,612 registered holders with addresses in the United States. As of such date, 32.5% of the A Shares were held in the form of A Share ADSs, each representing the right to receive 20 A Shares, and
99.6% of the A Share ADSs were held by 4,194 registered holders with addresses in the United States. Each A Share may be exchanged at the option of the holder for one L Share.

We have no information concerning holders with registered addresses in the United States that hold:

RELATED PARTY TRANSACTIONS

We receive consulting services from AT&T, which is one of our major shareholders, pursuant to a management services agreement and
amendments covering successive periods. The most recent amendment covered 2013, and we expect to agree on an amendment covering 2014. We paid U.S.$10 million in 2013 and U.S.$10 million in 2012, respectively, to AT&T in compensation for its
services. We also have agreements with AT&TI and its affiliates that provide for the completion of calls in our respective countries of operation, and our subsidiary TracFone purchases airtime from AT&T.

Our subsidiaries purchase materials or services from a variety of companies that may be deemed for certain purposes to be under common control
with us, including Grupo Carso and Grupo Financiero Inbursa and their respective subsidiaries. These services include insurance and banking services provided by Grupo Financiero Inbursa and its subsidiaries. In addition, we sell products in Mexico
through the Sanborns and Sears store chains. Some of our subsidiaries also purchase network construction services and materials from subsidiaries of Grupo Carso. Our subsidiaries purchase these materials and services on terms no less favorable than
they could obtain from unaffiliated parties, and would have access to other sources if our related parties ceased to provide them on competitive terms.

In November 2010, we entered into a revolving credit agreement with Banco Inbursa, S.A., Institución de Banca Múltiple, Grupo
Financiero Inbursa, which may be deemed for certain purposes to be under common control with us. The agreement provides a line of credit to us or our subsidiaries for up to U.S.$400 million, of which no drawings are outstanding.

In March 2014, we purchased shares representing 3.1% of the outstanding shares of Telekom Austria from Inmobiliaria Carso and Control
Empresarial de Capitales, S.A. de C.V, which may be deemed for certain purposes to be under common control with us.

In April 2014, our shareholders approved a dividend of Ps.0.24 per share, payable in two equal installments in
July and November 2014. The declaration, amount and payment of dividends by América Móvil is determined by majority vote of the holders of AA Shares and A Shares, generally on the recommendation of the Board of Directors, and depends
on our results of operations, financial condition, cash requirements, future prospects and other factors considered relevant by the holders of AA Shares and A Shares.

Our bylaws provide that holders of AA Shares, A Shares and L Shares participate equally on a per-share basis in dividend payments and other
distributions, subject to certain preferential dividend rights of holders of L Shares. See BylawsDividend Rights and BylawsPreferential Rights of L Shares under Item 10.

BYLAWS

Set forth below is a brief summary of certain significant provisions in our bylaws and Mexican law. This description does not purport to be
complete and is qualified by reference to our bylaws, which have been filed as an exhibit to this annual report. For a description of the provisions of our bylaws relating to our Board of Directors, Executive and Audit and Corporate Practices
Committees and External Auditor, see Directors, Senior Management and Employees under Item 6.

Organization and Register

América Móvil is a sociedad anónima bursátil de capital variable organized in Mexico under the
Mexican General Corporations Law and the Mexican Securities Market Law. It was registered in the Public Registry of Commerce of Mexico City on October 13, 2000 under the number 263,770.

Corporate Purpose

Our main corporate
purpose, as set out in Article Three of our bylaws, is to promote, incorporate, organize, exploit, acquire and participate in the capital stock or assets of all types of civil or commercial companies, partnerships and industrial, commercial, service
or other entities, whether domestic or foreign, and to participate in the management or liquidation thereof.

Share Capital

Our capital stock comprises AA Shares, without par value, A Shares, without par value and L Shares, without par value. All of the outstanding
shares are fully paid and non-assessable.

AA Shares and A Shares have full voting rights. Holders of L Shares may vote only in
limited circumstances as described under Voting Rights under this Item 10. The rights of holders of all series of capital stock are identical except for the voting rights and the limitations on non-Mexican ownership of AA Shares.
The AA Shares, which must always represent at least 51% of the combined AA Shares and A Shares, may be owned only by holders that qualify as Mexican investors as defined in the Foreign Investment Law (Ley de Inversión Extranjera) and
our bylaws. See Limitations on Share Ownership under this Item 10.

Each AA Share or A Share may be
exchanged at the option of the holder for one L Share, provided that the AA Shares may never represent less than 20% of our outstanding capital stock or less than 51% of our combined AA Shares and A Shares.

On April 27, 2011, our shareholders approved a two-for-one stock split which became effective in June 2011.

Voting Rights

Each AA Share and A Share
entitles the holder thereof to one vote at any meeting of our shareholders. Each L Share entitles the holder to one vote at any meeting at which holders of L Shares are entitled to vote. Holders of L Shares are entitled to vote to elect only two
members of the Board of Directors and the corresponding alternate directors, as well as on the following matters:



| |  |  | the transformation of América Móvil from one type of company to another;
| | - |  | ------------------------------------------------------------------------



| |  |  | any merger of América Móvil;
| | - |  | ----------------------------



| |  |  | the extension of our authorized corporate life;
| | - |  | -----------------------------------------------



103

##### Table of Contents

| |  |  | our voluntary dissolution;
| | - |  | --------------------------



| |  |  | any change in our corporate purpose;
| | - |  | ------------------------------------



| |  |  | any transaction that represents 20% or more of the Companys consolidated assets;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | any change in our state of incorporation;
| | - |  | -----------------------------------------



| |  |  | removal of our shares from listing on the Mexican Stock Exchange or any foreign stock exchange; and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | any action that would prejudice the rights of holders of L Shares.
| | - |  | ------------------------------------------------------------------

A resolution on any of the
specified matters requires the affirmative vote of both a majority of all outstanding shares and a majority of the AA Shares and the A Shares voting together.

Under Mexican law, holders of shares of any series are also entitled to vote as a class on any action that would prejudice the rights of
holders of shares of such series, and a holder of shares of such series would be entitled to judicial relief against any such action taken without such a vote. There are no other procedures for determining whether a proposed shareholder action
requires a class vote, and Mexican law does not provide extensive guidance on the criteria to be applied in making such a determination.

Shareholders Meetings

General
shareholders meetings may be ordinary meetings or extraordinary meetings. Extraordinary general meetings are those called to consider certain matters specified in Article 182 of the Mexican General Corporations Law, including, principally,
amendments of the bylaws, liquidation, merger and transformation from one type of company to another, as well as to consider the removal of our shares from listing on the Mexican Stock Exchange or any foreign stock exchange. General meetings called
to consider all other matters are ordinary meetings. The two directors elected by the holders of L Shares are elected at a special meeting of holders of L Shares. All other matters on which holders of L Shares are entitled to vote would be
considered at an extraordinary general meeting.

A special meeting of the holders of L Shares must be held each year for the election or
reelection of directors. An ordinary general meeting of the holders of AA Shares and A Shares must be held each year to consider the approval of the financial statements for the preceding fiscal year, to elect or reelect directors and to determine
the allocation of the profits of the preceding year. Transactions that represent 20% or more of our consolidated assets in any fiscal year must be approved by an ordinary general shareholder meeting of all shareholders, including holders of L
Shares.

The quorum for an ordinary general meeting of the AA Shares and A Shares is 50% of such shares, and action may be taken by a
majority of the shares present. If a quorum is not available, a second meeting may be called at which action may be taken by a majority of the AA Shares and A Shares present, regardless of the number of such shares. Special meetings of holders of L
Shares are governed by the same rules applicable to ordinary general meetings of holders of AA Shares and A Shares. The quorum for an extraordinary general meeting at which holders of L Shares may not vote is 75% of the AA Shares and A Shares, and
the quorum for an extraordinary general meeting at which holders of L Shares are entitled to vote is 75% of the outstanding capital stock. If a quorum is not available in either case, a second meeting may be called and action may be taken, provided
a majority of the shares entitled to vote is present. Whether on first or second call, actions at an extraordinary general meeting may be taken by a majority vote of the AA Shares and A Shares outstanding and, on matters which holders of L Shares
are entitled to vote, a majority vote of all the capital stock.

##### Table of Contents

Holders of 20% of our outstanding capital stock may have any shareholder action set aside by
filing a complaint with a court of law within 15 days after the close of the meeting at which such action was taken and showing that the challenged action violates Mexican law or our bylaws. In addition, any holder of our capital stock may bring an
action at any time within five years challenging any shareholder action. Relief under these provisions is only available to holders:



| |  |  | who were entitled to vote on, or whose rights as shareholders were adversely affected by, the challenged shareholder action; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | whose shares were not represented when the action was taken or, if represented, were voted against it.
| | - |  | ------------------------------------------------------------------------------------------------------

Shareholders meetings may be called by the Board of Directors, its chairman, its corporate secretary, the Chairman of the Audit and
Corporate Practices Committee or a court. The Chairman of the Board of Directors or the Chairman of the Audit and Corporate Practices Committee may be required to call a meeting of shareholders by the holders of 10% of the outstanding capital stock.
Notice of meetings must be published in the Official Gazette or a newspaper of general circulation in Mexico City at least 15 days prior to the meeting.

Under our bylaws, a shareholder is required to deposit its shares with a custodian in order to attend a shareholders meeting. A holder
of ADSs will not be able to meet this requirement, and accordingly is not entitled to attend shareholders meetings. A holder of ADSs is entitled to instruct the depositary as to how to vote the shares represented by ADSs, in accordance with
procedures provided for in the deposit agreements, but a holder of ADSs will not be able to vote its shares directly at a shareholders meeting or to appoint a proxy to do so.

Dividend Rights

At the annual ordinary
general meeting of holders of AA Shares and A Shares, the Board of Directors submits our financial statements for the previous fiscal year, together with a report thereon by the Board, to the holders of AA Shares and A Shares for approval. The
holders of AA Shares and A Shares, once they have approved the financial statements, determine the allocation of our net profits for the preceding year. They are required by law to allocate 5% of such net profits to a legal reserve, which is not
thereafter available for distribution except as a stock dividend, until the amount of the legal reserve equals 20% of our capital stock. The remainder of net profits is available for distribution.

All shares outstanding at the time a dividend or other distribution is declared are entitled to participate in such dividend or other
distribution, subject to certain preferential rights of the L Shares. See Preferential Rights of L Shares under this Item 10.

Preferential Rights of L Shares

Holders
of L Shares are entitled to receive a cumulative preferred annual dividend of 0.00042 pesos per share before any dividends are payable in respect of any other class of América Móvil capital stock. If we pay dividends with respect to
any fiscal year in addition to the L Share preferred dividend, such dividends must be allocated:



| |  |  | first, to the payment of dividends with respect to the A Share and AA Shares, in an equal amount per share, up to the amount of the L Share preferred dividend, and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | second, to the payment of dividends with respect to all classes of América Móvil shares such that the dividend per share is equal.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------

Upon our liquidation, holders of L Shares will be entitled to a liquidation preference equal to:



| |  |  | accrued but unpaid L Share preferred dividends, plus
| | - |  | ----------------------------------------------------



| |  |  | 0.00833 pesos per share (representing the capital attributable to such shares as set forth in our bylaws) before any distribution is made in respect of our other capital stock in accordance with Article 113 of the
Mexican General Corporations Law.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



105



---

##### Table of Contents

Following payment in full of any such amount, holders of AA Shares and A Shares are entitled to
receive, if available, an amount per share equal to the liquidation preference paid per L Share. Following payment in full of the foregoing amounts, all shareholders share equally, on a per-share basis, in any remaining amounts payable in respect of
our capital stock.

Limitation on Capital Increases

Our bylaws require that any capital increase be represented by new shares of each series in proportion to the number of shares of each series
outstanding.

Preemptive Rights

In
the event of a capital increase, except in certain circumstances such as mergers, convertible debentures, public offers and placement of repurchased shares, a holder of existing shares of a given series has a preferential right to subscribe for a
sufficient number of shares of the same series to maintain the holders existing proportionate holdings of shares of that series. Preemptive rights must be exercised within the next 15 calendar days following the publication of notice of the
capital increase in the Official Gazette and a newspaper of general circulation in Mexico City. Under Mexican law, preemptive rights cannot be traded separately from the corresponding shares that give rise to such rights. As a result, there is no
trading market for the rights in connection with a capital increase. Holders of ADSs may exercise preemptive rights only through the depositary. We are not required to take steps that may be necessary to make this possible.

Limitations on Share Ownership

Our
bylaws provide that at least 20% of our capital stock must consist of AA Shares. Our bylaws also provide that A Shares and L Shares together cannot represent more than 80% of our capital stock. AA Shares can only be held or acquired by:



| |  |  | Mexican citizens;
| | - |  | -----------------



| |  |  | Mexican corporations whose capital stock is held completely by Mexican citizens;
| | - |  | --------------------------------------------------------------------------------



| |  |  | Mexican corporations in which at least 51% of the capital stock may only be held or acquired by (i) Mexican citizens or (ii) Mexican corporations;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Mexican credit and insurance companies;
| | - |  | ---------------------------------------



| |  |  | Mexican investment companies operating under the Investment Companies Law (Ley de Sociedades de Inversión) and Mexican institutional investors as defined in the Mexican Securities Market Law; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Trusts expressly permitted to acquire AA Shares in accordance with Mexican law and in which (i) the majority of the trustees rights are held by Mexican citizens, corporations whose capital stock is held by
Mexican citizens in its majority, and Mexican credit, insurance and investment companies, or (ii) the AA Shares controlled by the trust represent a minority of the outstanding AA Shares and are voted in the same manner as the majority of the
outstanding AA Shares.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If foreign governments or states acquire our AA Shares, such shares would immediately be rendered
without effect or value.

Non-Mexican investors cannot hold AA Shares except through trusts that effectively neutralize their votes.
AT&T, Inc., one of our shareholders, holds its AA Shares through a trust that has been approved by relevant authorities in Mexico for this purpose.

Our bylaws were amended in 2010 to add a provision called a foreign exclusion clause. Under the foreign exclusion clause, ownership of
América Móvil shares is restricted to holders that qualify as Mexican investors

##### Table of Contents

under Mexican law. The foreign exclusion clause does not apply to the L Shares, and under transitional provisions adopted by the shareholders it does not limit foreign ownership of A Shares
outstanding as of the date of the shareholders meeting approving the amendment.

Restrictions on Certain Transactions

Our bylaws provide that any transfer of more than 10% of the combined A Shares and AA Shares, effected in one or more transactions by any
person or group of persons acting in concert, requires prior approval by our Board of Directors. If the Board of Directors denies such approval, however, Mexican law and our bylaws require it to designate an alternate transferee, who must pay market
price for the shares as quoted on the Mexican Stock Exchange.

Restrictions on Deregistration in Mexico

Our shares are registered with the RNV maintained by the CNBV, as required under the Mexican Securities Market Law and regulations issued by
the CNBV.

If we wish to cancel our registration, or if it is cancelled by the CNBV, we are required to conduct a public offer to purchase
all the outstanding shares prior to such cancellation. Such offer shall be addressed exclusively to those persons other than the members of the controlling group of shareholders, who were shareholders or holders of other securities representing such
shares (i) as of the date set forth by the CNBV, if the registration is cancelled by resolution thereof, or (ii) as of the date of the resolution adopted by the general extraordinary shareholders meeting, if the registration is cancelled
voluntarily.

Our bylaws provide that if, after the public offer is concluded, there are still outstanding shares held by the general
public, América Móvil will be required to create a trust for a period of six months, into which we will be required to contribute funds in an amount sufficient to purchase, at the same price as the offer price, the number of
outstanding shares held by the general public that did not consent to the offer.

Unless the CNBV authorizes otherwise, upon the prior
approval of the Board of Directors, which must take into account the opinion of the audit and corporate practices committee, the offer price will be the higher of: (i) the average of the closing price during the previous 30 days on which the
shares may have been quoted, or (ii) the book value of the shares in accordance with the most recent quarterly report submitted to the CNBV and to the Mexican Stock Exchange.

The voluntary cancellation of the registration shall be subject to (i) the prior authorization of the CNBV, and (ii) the
authorization of not less than 95% of the outstanding capital stock in a general extraordinary shareholders meeting.

Tender Offer Requirement

Our bylaws provide that any purchasers or group of purchasers that obtain or increase a significant participation (i.e.,
30% or more) in our capital stock, without conducting a previous public offer in accordance with the applicable rules issued by the CNBV, would not have the right to exercise the corporate rights of their shares, and that we will not register such
shares in the share registry book.

Other Provisions

Variable capital. We are permitted to issue shares constituting fixed capital and shares constituting variable capital. All of
our outstanding shares of capital stock constitute fixed capital. The issuance of variable capital shares, unlike the issuance of fixed capital shares, does not require an amendment of the bylaws, although it does require a majority vote of the AA
Shares and the A Shares.

##### Table of Contents

Forfeiture of shares. As required by Mexican law, our bylaws provide that any
non-Mexican person who at the time of incorporation or at any time thereafter acquires an interest or participation in our capital shall be considered, by virtue thereof, as Mexican in respect thereof and shall be deemed to have agreed not to invoke
the protection of his own government, under penalty, in case of breach of such agreement, of forfeiture to the nation of such interest or participation. Under this provision a non-Mexican shareholder is deemed to have agreed not to invoke the
protection of his own government by asking such government to interpose a diplomatic claim against the Mexican government with respect to the shareholders rights as a shareholder, but is not deemed to have waived any other rights it may have,
including any rights under the U.S. securities laws, with respect to its investment in América Móvil. If the shareholder invokes such governmental protection in violation of this agreement, its shares could be forfeited to the Mexican
government. Mexican law requires that such a provision be included in the bylaws of all Mexican corporations unless such bylaws prohibit ownership of shares by non-Mexican persons.

Exclusive jurisdiction. Our bylaws provide that legal actions relating to the execution, interpretation or performance of the bylaws
shall be brought only in Mexican courts.

Duration. América Móvils existence under the bylaws continues
indefinitely.

Purchase of our own shares. According to the bylaws, we may repurchase our shares on the Mexican Stock Exchange at
any time at the then prevailing market price. Any such repurchase must conform to guidelines established by the Board of Directors, and the amount available to repurchase shares must be approved by the general ordinary shareholders meeting.
The economic and voting rights corresponding to repurchased shares may not be exercised during the period in which we own such shares, and such shares are not deemed to be outstanding for purposes of calculating any quorum or vote at any
shareholders meeting during such period.

Conflict of interest. A shareholder that votes on a business transaction in which
its interest conflicts with América Móvils may be liable for damages, but only if the transaction would not have been approved without its vote.

Appraisal rights. Whenever shareholders approve a change of corporate purposes, change of nationality of the corporation or
transformation from one type of company to another, any shareholder entitled to vote on such change that has voted against it may withdraw from América Móvil and receive the book value attributable to its shares, provided it exercises
its right within 15 days following the adjournment of the meeting at which the change was approved.

Rights of Shareholders

The protections afforded to minority shareholders under Mexican law are different from those in the United States and many other
jurisdictions. The substantive law concerning fiduciary duties of directors has not been the subject of extensive judicial interpretation in Mexico, unlike many states in the United States where duties of care and loyalty elaborated by judicial
decisions help to shape the rights of minority shareholders. Mexican civil procedure does not contemplate class actions, which permit shareholders in U.S. courts to bring actions on behalf of other shareholders. Shareholders cannot challenge
corporate action taken at a shareholders meeting unless they meet certain procedural requirements, as described above under Shareholders Meetings.

As a result of these factors, in practice it may be more difficult for our minority shareholders to enforce rights against us or our directors
or controlling shareholders than it would be for shareholders of a U.S. company.

In addition, under the U.S. securities laws, as a
foreign private issuer we are exempt from certain rules that apply to domestic U.S. issuers with equity securities registered under the Exchange Act, including the proxy solicitation rules and the rules requiring disclosure of share ownership by
directors, officers and certain shareholders. We are also exempt from the corporate governance requirements of the NYSE and NASDAQ,

##### Table of Contents

except that since July 2005 we are subject to the requirements concerning audit committees and independent directors adopted pursuant to the Sarbanes-Oxley Act of 2002. For a comparison of our
corporate governance policies and the corporate governance requirements of the NYSE and NASDAQ, see Item 16G.

Enforceability of Civil Liabilities

América Móvil is organized under the laws of Mexico, and most of our directors, officers and controlling persons reside
outside the United States. In addition, all or a substantial portion of our assets and their assets are located in Mexico. As a result, it may be difficult for investors to effect service of process within the United States on such persons. It may
also be difficult to enforce against them, either inside or outside the United States, judgments obtained against them in U.S. courts, or to enforce in U.S. courts judgments obtained against them in courts in jurisdictions outside the United States,
in any action based on civil liabilities under the U.S. federal securities laws. There is doubt as to the enforceability against such persons in Mexico, whether in original actions or in actions to enforce judgments of U.S. courts, of liabilities
based solely on the U.S. federal securities laws.

CERTAIN CONTRACTS

A number of our subsidiaries and affiliates hold concessions and licenses granted by regulatory authorities in the countries in which they
operate. See Regulation under Item 4.

EXCHANGE CONTROLS

Mexico has had a free market for foreign exchange since 1991, and the government has allowed the peso to float freely against the U.S. dollar
since December 1994. There can be no assurance that the government will maintain its current foreign exchange policies. See Exchange Rates under Item 3.

TAXATION

The following summary contains a description of certain Mexican federal and U.S. federal income tax consequences of the acquisition, ownership
and disposition of L Shares, A Shares, L Share ADSs or A Share ADSs, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a decision to purchase, hold or sell shares or ADSs.

The Convention for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion and the Protocols thereto between the United States
and Mexico entered into force on January 1, 1994 and has been amended by an additional protocol that entered into force on July 3, 2003 (together, the Tax Treaty). The United States and Mexico have also entered into an
agreement concerning the exchange of information with respect to tax matters.

This discussion does not constitute, and should not be
considered as, legal or tax advice to holders. The discussion is for general information purposes only and is based upon the federal tax laws of Mexico (including the Mexican Income Tax Law and the Mexican Federal Tax Code) and the United States as
in effect on the date of this annual report (including the Tax Treaty), which are subject to change, and such changes may have retroactive effect. Holders of shares or ADSs should consult their own tax advisors as to the Mexican, U.S. or other tax
consequences of the purchase, ownership and disposition of shares or ADSs, including, in particular, the effect of any foreign, state or local tax laws.

Mexican Tax Considerations

The following is a general summary of the principal consequences under the Mexican Income Tax Law (Ley del Impuesto sobre la Renta, or
the Mexican Income Tax Law) and rules and regulations thereunder, as currently in effect, of an investment in shares or ADSs by a holder that is not a resident of Mexico and that will not hold shares or ADSs or a beneficial interest
therein in connection with the conduct of a trade or business through a permanent establishment in Mexico (a nonresident holder).

For purposes of Mexican taxation, the definition of residence is highly technical and residence arises in several situations. Generally, an
individual is a resident of Mexico if he or she has established his or her home or center of vital interests in Mexico, and a corporation is considered a resident if it has its place of effective management in Mexico. However, any determination of
residence should take into account the particular situation of each person or legal entity.

If a legal entity or an individual is deemed
to have a permanent establishment in Mexico for Mexican tax purposes, all income attributable to that permanent establishment will be subject to Mexican income taxes, in accordance with applicable tax laws.

This summary does not purport to be a comprehensive description of all the Mexican tax considerations that may be relevant to a decision to
purchase, own or dispose of the shares. In particular, this summary (A) does not describe any tax consequences arising under the laws of any state, locality, municipality or taxing jurisdiction other than certain federal laws of Mexico and
(B) does not address all of the Mexican tax consequences that may be applicable to specific holders of the shares, including a holder:

(i) whose shares were not acquired through the Mexican Stock Exchange or other markets authorized by the Ministry of Finance
and Public Credit (Secretaría de Hacienda y Crédito Público) or the Mexican Federal Tax Code;

(ii) of shares or ADSs that controls the Company;

(iii) that holds 10% or more of our shares;

(iv) that is part of a group of persons for purposes of Mexican law that controls the Company (or holds 10% or more of our
shares);

(v) that is resident of Mexico or is a corporation resident in a tax haven (as defined by the Mexican Income Tax
Law); or

(vi) whose shares are sold outside the Mexican Stock Exchange or outside non-restricted open market transactions.

Tax Treaties

Provisions of the Tax Treaty that may affect the taxation of certain U.S. holders (as defined below) are summarized below.

The Mexican Income Tax Law has established procedural requirements for a nonresident holder to be entitled to benefits under any of the tax
treaties to which Mexico is a party, including on dispositions and dividends. These procedural requirements include among others the obligation to (i) prove tax treaty residence, (ii) file tax calculations made by an authorized certified
public accountant or an informational tax statement, as the case may be, and (iii) appoint representatives in Mexico for taxation purposes. Parties related to the issuer may be subject to additional procedural requirements.

Payment of Dividends

Dividends, either in cash or in kind, paid with respect to the L Shares, A Shares, L Share ADSs or A Share ADSs will generally be subject to a
10% Mexican withholding tax (provided that no Mexican withholding tax



110



---

##### Table of Contents

will apply to distributions of net taxable profits generated before 2014). Nonresident holders could be subject to a lower tax rate, to the extent that they are eligible for benefits under an
income tax treaty to which Mexico is a party.

Taxation of Dispositions

Under current Mexican law and regulations, the tax rate on income realized by a nonresident holder from a disposition of shares through the
Mexican Stock Exchange is generally 10%, which is applied to the net gain realized on the disposition. The aforementioned tax is payable through withholding made by intermediaries. However, such withholding should not apply to the extent that a
nonresident holder is eligible for benefits under an income tax treaty to which Mexico is a party, regardless whether the treaty in question provides relief by its terms for capital gains tax, and without any other further formalities. In order to
benefit from this exemption, however, a record owner must provide sufficient evidence to the relevant intermediaries to certify the holders residence in a country with which Mexico has entered into an income tax treaty.

New withholding tax rules were imposed by the new Mexican tax regulations applicable as of 2014. Although practices under such provisions are
still developing we believe that:



| |  |  | disposition of ADSs (as opposed to directly held shares) should not be subject to any Mexican withholding tax if the transactions are carried out through other securities exchanges or markets approved by the Ministry of
Finance and Public Credit, or other securities exchanges or markets with ample securities trading that are located in countries with which Mexico has entered into an income tax treaty, such as the NYSE, NASDAQ and Latibex; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the sale or other transfer or disposition of shares not carried out through the Mexican Stock Exchange and not held in the form of ADSs will be subject to a 25.0% tax rate in Mexico, which is applicable to the gross
proceeds realized from the sale. Alternatively, a nonresident holder may, subject to certain requirements, elect to pay taxes on the gains realized from the sale of shares on a net basis at a rate of 35.0%.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Pursuant to the Tax Treaty, gains realized by a U.S. resident which is eligible to receive benefits pursuant to the Tax Treaty from the sale
or other disposition of shares or ADSs, even if the sale or disposition is not carried out under the circumstances described in the preceding paragraphs, will not be subject to Mexican income tax, provided that the gains are not attributable to a
permanent establishment or a fixed base in Mexico, and further provided that such U.S. holder owned less than 25% of the shares representing our capital stock (including ADSs), directly or indirectly, during the 12-month period preceding such
disposition. U.S. residents should consult their own tax advisors as to their possible eligibility under the Tax Treaty.

Gains and gross
proceeds realized by other nonresident holders that are eligible to receive benefits pursuant to other income tax treaties to which Mexico is a party may be exempt from Mexican income tax in whole or in part. Non-U.S. holders should consult their
own tax advisors as to their possible eligibility under such treaties.

Other Mexican Taxes

A nonresident holder generally will not be liable for estate, inheritance or similar taxes with respect to its holdings of shares or ADSs;
provided, however, that gratuitous transfers of shares or ADSs may in certain circumstances result in imposition of a Mexican tax upon the recipient. There are no Mexican stamp, issue registration or similar taxes payable by a nonresident holder
with respect to shares or ADSs.

U.S. Federal Income Tax Considerations

The following is a summary of certain U.S. federal income tax consequences to U.S. holders (as defined below) of the acquisition, ownership and
disposition of shares or ADSs. The summary does not purport to be a



111



---

##### Table of Contents

comprehensive description of all of the tax consequences of the acquisition, ownership or disposition of shares or ADSs. The summary applies only to U.S. holders that will hold their shares or
ADSs as capital assets and does not apply to special classes of U.S. holders such as dealers in securities or currencies, holders with a functional currency other than the U.S. dollar, holders of 10% or more of our voting shares (whether held
directly or through ADSs or both), tax-exempt organizations, banks, insurance companies, or other financial institutions, holders liable for the alternative minimum tax, securities traders electing to account for their investment in their shares or
ADSs on a mark-to-market basis, entities that are treated for U.S. federal income tax purposes as partnerships or other pass-through entities or equity holders therein, and persons holding their shares or ADSs in a hedging transaction or as part of
a straddle or conversion transaction.

For purposes of this discussion, a U.S. holder is a holder of shares or ADSs that is:



| |  |  | a citizen or resident of the United States of America,
| | - |  | ------------------------------------------------------



| |  |  | a corporation (or other entity taxable as a corporation) organized under the laws of the United States of America or any state thereof, or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | otherwise subject to U.S. federal income taxation on a net income basis with respect to the shares or ADSs.
| | - |  | -----------------------------------------------------------------------------------------------------------

Each U.S. holder should consult such holders own tax advisor concerning the overall tax consequences to it of the ownership or
disposition of shares or ADSs that may arise under foreign, state and local laws.

Treatment of ADSs

In general, a U.S. holder of ADSs will be treated as the owner of the shares represented by those ADSs for U.S. federal income tax purposes.
Deposits or withdrawals of shares by U.S. holders in exchange for ADSs will not result in the realization of gain or loss for U.S. federal income tax purposes. U.S. holders that withdraw any shares should consult their own tax advisors regarding the
treatment of any foreign currency gain or loss on any pesos received in respect of such shares.

Taxation of Distributions

In general, a U.S. holder will treat the gross amount of distributions we pay, without reduction for Mexican withholding tax, as
dividend income for U.S. federal income tax purposes to the extent of our current and accumulated earnings and profits. Because we do not expect to maintain calculations of our earnings and profits under U.S. federal income tax principles, it is
expected that distributions paid to U.S. holders generally will be reported as dividends. In general, the gross amount of any dividends will be includible in the gross income of a U.S. holder as ordinary income on the day on which the dividends are
received by the U.S. holder, in the case of shares, or by the depositary, in the case of ADSs. Dividends will be paid in pesos and will be includible in the income of a U.S. holder in a U.S. dollar amount calculated by reference to the exchange rate
in effect on the date that they are received by the U.S. holder, in the case of shares, or by the depositary, in the case of ADSs (regardless of whether such pesos are in fact converted into U.S. dollars on such date). If such dividends are
converted into U.S. dollars on the date of such receipt, a U.S. holder generally should not be required to recognize foreign currency gain or loss in respect of the dividends. U.S. holders should consult their own tax advisors regarding the
treatment of foreign currency gain or loss, if any, on any pesos received by a U.S. holder or depositary that are converted into U.S. dollars on a date subsequent to receipt. Dividends paid by us will not be eligible for the dividends-received
deduction allowed to corporations under the U.S. Internal Revenue Code of 1986, as amended (the Code).

The amount of Mexican
tax withheld generally will give rise to a foreign tax credit or deduction for U.S. federal income tax purposes. Dividends generally will constitute passive category income for purposes of the



112



---

##### Table of Contents

foreign tax credit (or in the case of certain U.S. holders, general category income). The foreign tax credit rules are complex. U.S. holders should consult their own tax advisors with
respect to the implications of those rules for their investments in our shares or ADSs.

Subject to certain exceptions for short-term and
hedged positions, the U.S. dollar amount of dividends received by an individual with respect to the shares or ADSs will be subject to taxation at reduced rates if the dividends are qualified dividends. Dividends paid on the shares or
ADSs will be treated as qualified dividends if (i) (A) the shares or ADSs are readily tradable on an established securities market in the United States, or (B) we are eligible for the benefits of a comprehensive tax treaty with the
United States which the U.S. Treasury determines is satisfactory for purposes of this provision and which includes an exchange of information program, and (ii) we were not, in the year prior to the year in which the dividend was paid, and are
not, in the year in which the dividend is paid, a passive foreign investment company (PFIC). The ADSs are listed on the NYSE and the NASDAQ, and will qualify as readily tradable on an established securities market in the United
States so long as they are so listed. In addition, the U.S. Treasury has determined that the Tax Treaty meets the requirements for reduced rates of taxation, and we believe we are eligible for the benefits of the Tax Treaty. Based on our audited
consolidated financial statements and relevant market and shareholder data, we believe that we were not treated as a PFIC for U.S. federal income tax purposes with respect to the 2012 or 2013 taxable year. In addition, based on our audited
consolidated financial statements and our current expectations regarding the value and nature of our assets, the sources and nature of our income, and relevant market and shareholder data, we do not anticipate becoming a PFIC for our 2014 taxable
year. Holders of shares or ADSs should consult their own tax advisors regarding the availability of the reduced dividend tax rate in the light of their own particular circumstances.

Distributions of additional shares or ADSs to U.S. holders with respect to their shares or ADSs that are made as part of a pro rata
distribution to all of our shareholders generally will not be subject to U.S. federal income tax.

Taxation of Dispositions

A U.S. holder generally will recognize capital gain or loss on the sale or other disposition of the shares or ADSs in an amount
equal to the difference between the U.S. holders basis in such shares or ADSs (in U.S. dollars) and the amount realized on the disposition (in U.S. dollars, determined at the spot rate on the date of disposition if the amount realized is
denominated in a foreign currency). Gain or loss recognized by a U.S. holder on such sale or other disposition generally will be long-term capital gain or loss if, at the time of disposition, the shares or ADSs have been held for more than one year.
Long-term capital gain recognized by a U.S. holder that is an individual is taxable at reduced rates. The deductibility of a capital loss is subject to limitations.

Gain, if any, realized by a U.S. holder on the sale or other disposition of the shares or ADSs generally will be treated as U.S. source income
for U.S. foreign tax credit purposes. Consequently, if a Mexican withholding tax is imposed on the sale or disposition of the shares, a U.S. holder that does not receive significant foreign source income from other sources may not be able to derive
effective U.S. foreign tax credit benefits in respect of such Mexican taxes. U.S. holders should consult their own tax advisors regarding the application of the foreign tax credit rules to their investment in, and disposition of, the shares or ADSs.

Information Reporting and Backup Withholding

Dividends on, and proceeds from the sale or other disposition of, the shares or ADSs paid to a U.S. holder generally may be subject to the
information reporting requirements of the Code and may be subject to backup withholding unless the holder:



| |  |  | establishes that it is a corporation or other exempt holder, or
| | - |  | ---------------------------------------------------------------



| |  |  | provides an accurate taxpayer identification number on a properly completed Internal Revenue Service Form W-9 and certifies that no loss of exemption from backup withholding has occurred.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



113



---

##### Table of Contents

The amount of any backup withholding from a payment to a holder will be allowed as a credit
against the U.S. holders U.S. federal income tax liability and may entitle such holder to a refund, provided that certain required information is timely furnished to the Internal Revenue Service.

U.S. Tax Consequences for Non-U.S. holders

Distributions. A holder of shares or ADSs that is, with respect to the United States, a foreign corporation or a non-resident
alien individual (a non-U.S. holder) generally will not be subject to U.S. federal income or withholding tax on dividends received on shares or ADSs, unless such income is effectively connected with the conduct by the holder of a U.S.
trade or business.

Dispositions. A non-U.S. holder of shares or ADSs will not be subject to U.S. federal income or withholding tax
on gain realized on the sale of shares or ADSs, unless:



| |  |  | such gain is effectively connected with the conduct by the holder of a U.S. trade or business, or
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | in the case of gain realized by an individual holder, the holder is present in the United States for 183 days or more in the taxable year of the sale and certain other conditions are met.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Information Reporting and Backup Withholding.Although non-U.S. holders generally are exempt from backup withholding, a non-U.S. holder
may be required to comply with certification and identification procedures in order to establish its exemption from information reporting and backup withholding.

American Depositary Shares

The Bank of New York Mellon (the Depositary) serves as the depositary for our ADSs. ADS holders are required to pay various fees to
the Depositary, and the Depositary may refuse to provide any service for which a fee is assessed until the applicable fee has been paid.

ADS holders are required to pay the Depositary amounts in respect of expenses incurred by the Depositary or its agents on behalf of ADS
holders, including expenses arising from (i) taxes or other governmental charges, (ii) registration fees payable to us that may be applicable to the transfer of shares upon deposits to or withdrawals from the ADS program, (iii) cable,
telex, and facsimile transmission, (iv) conversion of foreign currency into U.S. dollars, or (v) servicing of the ADSs or the shares underlying ADSs. The Depositary may decide in its sole discretion to seek payment by either billing
holders or by deducting the fee from one or more cash dividends or other cash distributions.

ADS holders are also required to pay
additional fees for certain services provided by the Depositary, as set forth in the table below.



|                                                                                                                |  |

Payments by the Depositary

The Depositary reimburses us for certain expenses we incur in connection with the ADR program, subject to a ceiling agreed between us and the
Depositary from time to time. These reimbursable expenses currently include legal and accounting fees, listing fees, investor relations expenses and fees payable to service providers for the distribution of material to ADR holders. During the year
ended December 31, 2013, the Depositary paid US$5.0 million to us for reimbursable expenses.

|Item 15. | Controls and Procedures
|-------- | -----------------------

(a) Disclosure controls and procedures. We carried out
an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of
December 31, 2013. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures.
Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our
disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the
time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required
disclosure.

(b) 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 such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Under the supervision and with the participation of our management, including our Board
of Directors, Chief Executive Officer, Chief Financial Officer and other personnel, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal ControlIntegrated Framework
(1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Our 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 IFRS. Our internal control over financial reporting includes
those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with IFRS, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (iii) provide
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on our 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.

Based on our evaluation under the framework in Internal ControlIntegrated Framework, our management concluded that our internal control
over financial reporting was effective as of December 31, 2013.

Mancera, S.C., a member practice of Ernst & Young Global
Limited, an independent registered public accounting firm, our independent auditor, issued an attestation report on our internal control over financial reporting on April 28, 2014.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON INTERNAL CONTROL OVER FINANCIAL
REPORTING

The Board of Directors and Shareholders of

América Móvil, S.A.B. de C.V.

We
have audited América Móvil, S.A.B. de C.V. and subsidiaries internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control  Integrated Framework issued by the Committee
of Sponsoring Organizations of the Treadway Commission (the 1992 Framework) (the COSO criteria). América Móvil, S.A.B. de C.V. and subsidiaries 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 Annual 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 International Financial Reporting Standards, as issued by the International Accounting Standards Board. 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 International Financial Reporting Standards, as issued by the International Accounting Standards Board, 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, América Móvil,
S.A.B. de C.V. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated
statements of financial position of América Móvil, S.A.B. de C.V. and subsidiaries as of December 31, 2012 and 2013, and the related consolidated statements of comprehensive income, changes in equity and cash flows for each of the
three years in the period ended December 31, 2013, and our report dated April 28, 2014, expressed an unqualified opinion thereon.

Our corporate governance practices are governed by our bylaws,
the Mexican Securities Market Law and the regulations issued by the CNBV. We also comply with the Mexican Code of Best Corporate Practices (Código de Mejores Prácticas Corporativas), which was created in January 2001 by a group
of Mexican business leaders and was endorsed by both the CNBV and the Mexican Stock Exchange.

The table below discloses the significant
differences between our corporate governance practices and those required for U.S. Companies under the NYSE and NASDAQ listing standards.

be identified in a listed companys proxy statement (or annual report on Form 10-K or 20-F if the issuer does not file a proxy statement). Controlled companies are exempt from this requirement. A controlled company is one in which
more than 50% of the voting power for the election of directors is held by an individual, group or another company, rather than the public. Rules 5605(b)(1), 5615(c)(1) and (c)(2).
 As a controlled company, we would be exempt from this requirement if we were a
U.S. issuer. |  | Director Independence.Pursuant to the Mexican Securities Market Law, our shareholders are required to appoint a board
of directors of no more than 21 members, 25% of whom must be independent. Certain persons are per se non-independent, including insiders, control persons, major suppliers and any relatives of such persons. In accordance with the Mexican
Securities Market Law, our shareholders meeting is required to make a determination as to the independence of our directors, though such determination may be challenged by the CNBV.
 There is no exemption from the independence requirement for controlled
companies.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of

América
Móvil, S.A.B. de C.V.

We have audited the accompanying consolidated statements of financial position of América
Móvil, S.A.B. de C.V. and subsidiaries as of December 31, 2012 and 2013 and the related consolidated statements of comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31,
2013. 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 América Móvil, S.A.B. de C.V. and subsidiaries as of December 31, 2012 and 2013, and the consolidated results of their operations and their cash flows for each of the three years in the period
ended December 31, 2013, in conformity with International Financial Reporting Standards, as issued by the International Accounting Standards Board.

As discussed in Note 3, the Company retrospectively adopted International Accounting Standard 19, Employee Benefits (Revised) in 2013, which
included the disclosure of the January 1, 2012 consolidated statement of financial position.

We also have audited, in accordance
with the standards of the Public Company Accounting Oversight Board (United States), América Móvil, S.A.B. de C.V. and subsidiaries internal control over financial reporting as of December 31, 2013, based on criteria
established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 Framework) and our report dated April 28, 2014, expressed an unqualified opinion thereon.

2. Basis of Preparation of
the Consolidated Financial Statements and Summary of Significant Accounting Policies and Practices

a) Basis of preparation

The accompanying financial statements for all the periods presented have been prepared in conformity with International Financial Reporting
Standards , as issued by the International Accounting Standards Board (IASB) (hereafter referred to as IFRS), in force at December 31, 2013.

The consolidated financial statements have been prepared on the historical cost basis except for the derivative financial instruments and the
trust assets of post-employment and other employee benefit plans.

The preparation of these financial statements under IFRS requires the
use of critical estimates and assumptions that affect the amounts reported for certain assets and liabilities, as well as certain income and expenses. It also requires that management exercise judgment in the application of the Companys
accounting policies. Actual results could differ from these estimates and assumptions.

The financial statements provide comparative
information in respect of the previous period. In addition, América Móvil presents an additional statement of financial position at the beginning of the earliest period presented when there is a retrospective application of an
accounting policy, a retrospective restatement, or a reclassification of items in financial statements. An additional statement of financial position as at January 1, 2012 is presented in these financial statements for disclosure purposes due
to the retrospective application of IAS 19R, as explained in Note 3.

The Mexican peso is the functional currency and the reporting
currency of the parent Company in Mexico.

b) Business combination, consolidation and basis of translation of financial statements of foreign
subsidiaries

i) Business combination

Subsidiaries:

The consolidated financial
statements include the accounts of América Móvil, S.A.B. de C.V. and those of the subsidiaries over which the Company exercises control. The financial statements for the subsidiaries were prepared for the same period as the Company,
applying consistent accounting policies. All of the companies operate in the telecommunications field or provide services to companies relating to this activity.

The investments in associated companies in which the Company exercises significant influence are accounted for using the equity method,
whereby América Móvil recognizes its share in the net profit (losses) and equity of the associate.

The results of
operations of the subsidiaries and associates were included in the Companys consolidated financial statements beginning as of the month following their acquisition.

Non-controlling interests represent the portion of profits or losses and net assets not held by the Company. Non-controlling interests are
presented separately in the consolidated statement of comprehensive income and in equity in the consolidated statements of financial position separately from América Móvils own equity.

Acquisition-related cost is accounted as an expense in the consolidated statements of comprehensive income as they are incurred.

Goodwill is initially measured as the excess of the aggregate of the fair value of the consideration transferred plus any non-controlling
interest in the acquiree over the net value of the identifiable assets acquired and liabilities assumed as of the acquisition date.

If
the consideration paid is less than the fair value of the net assets of the acquired company, (in the case of a bargain purchase), the difference is recognized in the consolidated statements of comprehensive income.

ii) Consolidation and equity method

The
consolidated financial statements include the accounts of América Móvil, S.A.B. de C.V. and those of the subsidiaries over which the Company exercises control. Control is achieved when the Company is exposed, or has rights, to variable
returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Company controls an investee if and only if the Company has:



| | a) | Power over the investee (i.e. existing rights that give it the current ability to direct the relevant activities of the investee).
| | -- | ----------------------------------------------------------------------------------------------------------------------------------



| | b) | Exposure, or rights, to variable returns from its involvement with the investee, and
| | -- | ------------------------------------------------------------------------------------



| | c) | The ability to use its power over the investee to affect its returns.
| | -- | ---------------------------------------------------------------------

When the Company has
less than a majority of the voting or similar rights of an investee, the Company considers all relevant facts and circumstances in assessing whether it has power over an investee, including:



| | (i) | The contractual arrangement with the other vote holders of the investee
| | --- | -----------------------------------------------------------------------



| | (ii) | Rights arising from other contractual arrangements
| | ---- | --------------------------------------------------



| | (iii) | The Companys voting rights and potential voting rights.
| | ----- | --------------------------------------------------------



F-10

##### Table of Contents

The Company re-assesses whether or not it controls an investee if facts and circumstances
indicate that there are changes to one or more of the three elements of control. Consolidation of a subsidiary begins when the Company obtains control over the subsidiary and ceases when the Company loses control of the subsidiary. Assets,
liabilities, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated statements of comprehensive income from the date the Company gains control until the date the Company ceases to control the
subsidiary.

Profit or loss and each component of other comprehensive income (OCI) are attributed to the equity holders of the
parent of the Company and to the non-controlling interests. When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with the Companys accounting policies. All intercompany
balances and transactions are eliminated in the consolidated financial statements.

A change in the ownership interest of a subsidiary,
without a loss of control, is accounted for as an equity transaction. If the Company loses control over a subsidiary, it:



| | (i) | Derecognizes the assets (including goodwill) and liabilities of the subsidiary
| | --- | ------------------------------------------------------------------------------



| | (ii) | Derecognizes the carrying amount of any non-controlling interests
| | ---- | -----------------------------------------------------------------



| | (iii) | Derecognizes the cumulative translation differences recorded in equity
| | ----- | ----------------------------------------------------------------------



| | (iv) | Recognizes the fair value of the consideration received
| | ---- | -------------------------------------------------------



| | (v) | Recognizes the fair value of any investment retained
| | --- | ----------------------------------------------------



| | (vi) | Recognizes any surplus or deficit in profit or loss
| | ---- | ---------------------------------------------------



| | (vii) | Reclassifies the parents share of components previously recognized in OCI to profit or loss or retained earnings, as appropriate, as would be required if the Company had directly disposed of the related assets or
liabilities.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The financial statements for the subsidiaries were prepared for the same period as the holding company,
applying consistent accounting policies. All of the companies operate in the telecommunications field or provide services to companies relating to this activity.

Non-controlling interests refers to certain subsidiaries in which the Company does not hold 100% of the shares.

Non-controlling interests represent the portion of profits or losses and net assets not held by the Company. Non-controlling interests are
presented separately in the consolidated statements of comprehensive income and in equity in the consolidated statements of financial position separately from América Móvils own equity.

Acquisitions of non-controlling interests are accounted for as equity transactions. The difference between the book value and the subscription
price for acquired shares under common control are accounted for as an equity transaction within retained earnings.

Associates:

Associates are entities over which the Company has significant influence without having control. According to IAS 28, Investments in
Associates, significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies. Significant influence typically exists when an investor
holds from 20% to 50% of the voting power of an investee.

Investments in associates are accounted for using the equity method and are
initially recognized at cost. The Companys investment in associates includes goodwill identified on acquisition, net of any accumulated impairment losses.

##### Table of Contents

The Companys participation in the profits or losses of the associate after acquisition is
recognized in the consolidated statements of comprehensive income and its share of other comprehensive income after acquisition is recognized directly in other comprehensive income.

The Company assesses at each reporting date whether there is objective evidence that its investment in associates is impaired. If so, the
Company calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value.

The
Companys equity interest in the most significant subsidiaries and associated companies at December 31, 2012 and 2013 is as follows:



|                                                                              |  |                    |  |                               |       |   |      |  |       |

The financial information is consolidated, as appropriate, after the financial statements have been converted to IFRS in the respective local
currency and translated into the reporting currency.

##### Table of Contents

Since none of the subsidiaries operate in a hyperinflationary economic environment and the local
currency is their functional currency, the translation of their financial statements prepared under IFRS and denominated in their respective local currencies, are translated as follows:



| |  |  | all monetary assets and liabilities are translated at the prevailing exchange rate at the period closing;
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | all non-monetary assets and liabilities are translated at the prevailing exchange rate in effect at the period closing;
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | equity accounts are translated at the prevailing exchange rate at the time the capital contributions were made and the profits were generated;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | revenues, costs and expenses are translated at the average exchange rate during the applicable period;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | the difference resulting from the translation process is recognized in equity in the caption Effect of translation;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | the consolidated statements of cash flows are translated using the weighted-average exchange rate for the applicable period, and the resulting difference is shown in the consolidated statement of cash flows under the
heading Adjustment to cash flows due to exchange rate fluctuations.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The difference resulting from the
translation process is recognized in equity in the caption Effect of translation. At December 31, 2012 and 2013, the cumulative translation loss was Ps.(7,220,700) and Ps.(33,706,043), respectively.

c) Revenue recognition

Revenues are
recognized at the time the related service is rendered, provided that the revenue may be reliably measured, it is probable that the entity will receive the economic benefits associated with the transaction, the degree of completion of the
transaction may be reliably measured and there is high a certainty of collectability.

For the postpaid plans, the amount billed to
clients combines a fixed tariff for a specific quantity of services, plus the rates use above of the specified quantities (minutes in each plan). Expenses related to these services are recognized when the services are rendered.

The Company divides its main services into six types, as presented in the consolidated comprehensive income statements, as follows:



| |  |  | Mobile voice
| | - |  | ------------



| |  |  | Mobile data
| | - |  | -----------



| |  |  | Fixed voice
| | - |  | -----------



| |  |  | Fixed data
| | - |  | ----------



| |  |  | Paid TV
| | - |  | -------



| |  |  | Other related services
| | - |  | ----------------------

To recognize the multi-elements or multiple services at their fair
value, the Company has established the necessary indicators and metrics that allow it to assign to each type of element its fair value. In multi-element plans, these indicators are based on the price offered in each package, considering the number
of offered minutes and the data plans offered to subscribers.

Voice services



| |  | Monthly rent in post-paid plans is billed based on the associated plan and package rates, corresponding to when the services are provided. Revenues billed for services to be rendered in the future are initially recorded
as deferred revenues.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  | Revenues from local services are derived from charges for line installations, monthly rent for services and monthly charges for metered services based on the number of minutes used. These revenues depend on the number
of lines in service, the number of newly installed lines and the volume of minutes.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Revenues for interconnection services, which represent calls from other carriers entering the Companys mobile and fixed line networks (incoming interconnection services), are recognized at the time the service is
provided. Such services are invoiced based on rates previously agreed with other carriers.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Long-distance revenues originate from airtime or minutes used in making calls to a region or coverage area outside of the area where the customers service is activated. These revenues are recognized at the time
the service is provided.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Revenues from roaming charges are related to airtime charged to customers for making or receiving calls when visiting a local service area, country or region outside the local service area where the customers
service is activated. The related revenues are recognized at the time the service is provided based on the rates established and agreed upon by our subsidiaries with other domestic and international mobile carriers. See Note 23 on new regulation.
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Data



| |  | Value added services and other services include voice services and data transmission services (such as two-way and written messages, call information, ring tones and emergency services, among others). Revenues from such
services are recognized at the time they are provided or when the services are downloaded.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Revenues from internet services and the sale of point-to-point and point-to-multipoint links are recognized on the date of installation, which is similar to the date when the respective traffic begins.
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Revenues from corporate networks are obtained mainly from private lines and from providing virtual private network services. These revenues are recognized at the time the respective traffic begins.
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Pay television



| |  | Revenues from pay TV include payments for package deals, pay-per-view and advertising, all of which are recognized at the time the services are provided.
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------

Other related services

Equipment, accessories and
computers sale



| |  | Sales of mobile phone equipment and computers, which are made to authorized distributors and the general public, are recognized as revenue at the time the products are delivered and accepted by the customer and the
recovery of the amounts is probable. The distributors and general public do not have the right to return the products.
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The
majority of equipment sales are performed though distributors, though not exclusively, as a portion of equipment sales is performed through client service centers.

Marketing revenues



| |  | Advertising revenues earned through the publication of telephone directory are recognized over the life of the directories.
|- |  | ---------------------------------------------------------------------------------------------------------------------------

Transmission rights

Transmission rights
include exclusive rights for the transmission of the Winter Olympic Games and the Rio de Janeiro Olympics of 2016. The related costs and expenses (amortization of its investment) are recognized when the associated revenue is recognized.

##### Table of Contents

Points programs

Points programs are recognized as a reduction to revenues, since they effectively represent a decrease in the price of mobile services and
equipment. Upon redemption of points the deferred income is cancelled and the cost of equipment is expensed.

Commissions to distributors

Distribution agreements have three types of commissions related to postpaid plans.

Loyalty and activation commissions are accrued monthly as an expense based on statistical information about customer retention, sales volume
and the number of new customers obtained by each distributor. Retention commissions are paid when customers continue for a specified period. Volume commissions are paid at the time the distributor reaches prescribed ranges of activated clients.

In all three cases the fees are recognized within commercial, administrative and general expenses, as these fees are not reflected in the
price of services and products.

d) Cost of mobile equipment and computers

The cost of mobile equipment and computers is recognized at the time the related revenue is recognized. The costs relating to the sale of such
equipment are recognized in cost of sales and services.

e) Cost of services

These costs include the cost of call terminations in the networks of other carriers, the costs to link the fixed and mobile networks, payments
for long-distance services, rental costs for the use of infrastructure (links, ports and measured service), as well as message exchanges between carriers. Such costs are recognized at the time the service is received by the fixed or mobile carriers.
These costs also include last-mile costs and line installation costs, which are also recognized at the time the services are received.

Last mile installation costs and decoder-related charges are capitalized at the time of installation and depreciated over the average useful
life as the customer remains active in the Company.

f) Cash and cash equivalents

Cash and cash equivalents consist of bank deposits and highly liquid investments with maturities of less than three months. These investments
are stated at cost plus accrued interest, which is similar to their market value.

g) Allowance for bad debts

The Company periodically recognizes a provision for doubtful accounts based mainly on its past experience, the aging of its accounts
receivable, the delays in resolving its disputes with other carriers, and the market segments of its customers (governments, businesses and mass market).

Collection policies and procedures vary depending on the credit history of the customer, the credit granted, and the age of the unpaid calls
among other reasons.

The evaluation of collection risk of accounts receivables with related parties is performed annually based on an
examination of each related partys financial situation and the markets in which they operate.

h) Inventories

Inventories, which are mainly composed of cellular equipment, accessories, tablets and other devices, are initially recognized at historical
cost and are valued using the average cost method, without exceeding their net realizable value.



F-16



---

##### Table of Contents

The estimate of the realizable value of inventories on-hand is based on their age and turnover.

The difference between the sales price to the end user and the subsidized cost of equipment is recognized as an expense in the cost
of sales and service in the consolidated statements of comprehensive income, at the time of delivery.

i) Business combinations and goodwill

Business combinations are accounted for using the acquisition method, which in accordance with IFRS 3, Business
acquisitions, consists in general terms as follows:



| | i) | identify the acquirer
| | -- | ---------------------



| | ii) | determine the acquisition date
| | --- | ------------------------------



| | iii) | value the acquired identifiable assets and assumed liabilities
| | ---- | --------------------------------------------------------------



| | iv) | recognize the goodwill or a bargain purchase gain
| | --- | -------------------------------------------------

For acquired subsidiaries, goodwill
represents the difference between the purchase price and the fair value of the net assets acquired at the acquisition date. For acquired associates, the investment in associates includes goodwill identified on the acquisition date, net of any
impairment loss.

Goodwill is reviewed annually to determine its recoverability, or more often if circumstances indicate that the carrying
value of the goodwill might not be fully recoverable.

The possible loss of value in goodwill is determined by analyzing the recovery
value of the cash generating unit (or the group thereof) to which the goodwill is associated at the time it originated. If this recovery value is lower than the carrying value, an impairment loss is charged to results of operations.

For the years ended December 31, 2011, 2012 and 2013, no impairment losses were recognized for the goodwill shown in the Companys
consolidated statements of financial position.

j) Property, plant and equipment

Property, plant and equipment are recorded at acquisition cost, net of accumulated depreciation. Depreciation is computed on the cost of the
assets using the straight line method, based on the estimated useful lives of the related assets, beginning the month after they become available for use.

The Company periodically assesses the residual values, useful lives and depreciation methods associated with its property, plant and
equipment. If necessary, the effects of any changes in accounting estimates is recognized prospectively, at the closing of each period, in accordance with IAS 8, Accounting Policies, Changes in Accounting Estimates and Errors.

Borrowing costs that are incurred for general financing for construction in progress for periods exceeding six months are capitalized as
part of the cost of the asset. During 2011, 2012 and 2013 the borrowing costs that were capitalized amounted to Ps.3,845,609, Ps.3,152,811 and Ps.3,002,576, respectively.

Inventories for the operation of telephone plant are valued using the average cost method, without exceeding their net realizable value.

The valuations of inventories for the operation of telephone plant considered obsolete, defective or slow-moving, are reduced to their
estimated net realizable value. The estimate of the recovery value of inventories is based on their age and turnover.

##### Table of Contents

In addition to the purchase price and costs directly attributable to preparing an asset in terms
of its physical location and condition for use as intended by management, when required, the cost also includes the estimated costs for the dismantling and removal of the asset, and for restoration of the site where it is located. See Note 13b).

For property, plant and equipment made up of several components with different useful lives, the major individual components are
depreciated over their individual useful lives. Maintenance costs and repairs are expensed as incurred.

The net book value of property,
plant and equipment is removed from the statements of financial position at the time the asset is sold or when no future economic benefits are expected from its use or sale. Any gains or losses on the sale of property, plant and equipment represent
the difference between net proceeds of the sale, if any, and the net book value of the item at the time of sale. These gains or losses are recognized as either other operating income or operating expenses upon sale.

Annual depreciation rates are as follows:



|                                             |  |  |        |  
|-------------------------------------------- |  |  | ------ | -
|Telephone plant in operation:                |  |  |        |  
|Monitoring equipment and network performance |  |  | 20%-33 | %
|Base stations                                |  |  | 20     | %
|Switching and telephone exchanges            |  |  | 20     | %
|Towers, antennas and engineering works       |  |  | 10     | %
|Measuring equipment                          |  |  | 17     | %
|Buildings                                    |  |  | 3.33   | %
|Other assets                                 |  |  | 10%-33 | %

The carrying value of property, plant and equipment is reviewed whenever there are indicators of impairment in
such assets. Whenever an assets recovery value, which is the greater of the assets selling price and its value in use (the present value of future cash flows), is less than the assets net carrying value, the difference is
recognized as an impairment loss.

During the years ended December 31, 2011, 2012 and 2013, no impairment losses were recognized.

k) Licenses, trademarks and rights of use

i)
Licenses are recorded at acquisition cost, net of accumulated amortization.

Licenses to operate wireless telecommunications networks are
accounted for at cost or at fair value at their acquisition date.

The licenses that in accordance with government requirements are
categorized as automatically renewable, for a nominal cost and with substantially consistent terms, are considered by the Company as intangible assets with an indefinite useful life. Accordingly, they are not amortized. Licenses are amortized when
the Company does not have a basis to conclude that they have indefinite lives. Licenses are amortized using the straight-line method over a period ranging from 5 to 20 years, which represents the usage period of the assets. The payments to the
governments are recognized in the cost of service and equipment.

ii) Trademarks

Trademarks are recorded at their fair value at the valuation date when acquired, as determined by independent appraisers, and are amortized
using the straight-line method over a period ranging from 1 to 10 years.



F-18



---

##### Table of Contents

iii) Rights of use

Rights of use are recognized according to the amount paid for the right to carry traffic and are amortized over the period in which they are
granted.

The carrying value of the Companys licenses and trademarks with indefinite useful lives and with finite useful lives is
reviewed annually and whenever there are indicators of impairment in the value of such assets. When an assets recoverable amount, which is the higher of the assets fair value less disposal costs and its value in use (the present value of
future cash flows), is less than the assets carrying value, the difference is recognized as an impairment loss.

During the years
ended December 31, 2011, 2012 and 2013, no impairment losses were recognized.

l) Impairment in the value of long-lived assets

The Company has a policy in place for evaluating the existence of indicators of impairment in the carrying value of long-lived assets,
investments in associates, goodwill and intangible assets. When there are such indicators, or in the case of assets whose nature requires an annual impairment analysis (goodwill and intangible assets with indefinite useful lives), the Company
estimates the recoverable amount of the asset, which is the higher of its fair value, less disposal costs, and its value in use. Value in use is determined by discounting estimated future cash flows, applying a discount rate after taxes that
reflects the time value of money and taking into consideration the specific risks associated with the asset. When the recoverable amount of an asset is below its carrying value, impairment is considered to exist. In this case, the carrying value of
the asset is reduced to the assets recoverable amount, recognizing the loss in results of operations for the respective period. Depreciation and/or amortization expense of future periods is adjusted based on the new carrying value determined
for the asset over the assets remaining useful life. Impairment is computed individually for each asset. Recoverable amount is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of
those from other assets or group of assets.

In the estimation of impairments, the Company uses the strategic plans established for the
separate cash-generating units to which the assets are assigned. Such strategic plans generally cover a period from three to five years. For longer periods, beginning in the fifth year, projections are based on such strategic plans while applying a
constant or declining expected growth rate.

Key assumptions used in value in use calculations

The forecasts were performed by the Companys management in real terms (net of inflation) and in pesos with acquisition value as of
December 31, 2013.

In developing information for financial forecasts, premises and assumptions have been included that any other
market participant in similar conditions would consider.

Local synergies have not been taken into consideration that any other market
participant would not have taken into consideration to prepare similar forecasted financial information.

The assumptions used to develop
the financial forecasts were validated by the Companys Chief Executive Officer and the Chief Financial Officer for each of the cash-generating units (CGUs), taking into consideration the following:



| |  |  | Current subscribers and expected growth
| | - |  | ---------------------------------------



| |  |  | Type of subscribers (prepaid, postpaid, fixed line, multiple services)
| | - |  | ----------------------------------------------------------------------



| |  |  | Market situation and penetration expectations
| | - |  | ---------------------------------------------



| |  |  | New products and services
| | - |  | -------------------------

| |  |  | Investments in maintenance of the current assets

| |  |  | Investments in technology for expanding the current assets
| | - |  | ----------------------------------------------------------



| |  |  | Market consolidation and synergies
| | - |  | ----------------------------------

The foregoing forecasts could differ from the results
obtained over time; however, América Móvil prepares its estimates based on the current situation of each of the CGUs.

The
recoverable amounts are based on value in use. The value in use of CGUs is determined based on the method of discounted cash flows. The key assumptions used in projecting cash flows are: Adjusted EBITDA (which the Company defines as operating income
excluding currency fluctuations plus depreciation and amortization), capital expenditure (CAPEX) / margin on revenue, the change in working capital and the weighted average cost of capital (WACC) used to discount the
projected flows.

To determine the discount rate, América Móvil uses the WACC as determined for each of the cash generating
units in real terms and as described in following paragraphs.

The estimated discount rates to perform the IAS 36 Impairment of
assets, impairment test for each CGU consider market participants assumptions. Market participants were selected taking into consideration the size, operations and characteristics of the business that are similar to those of
América Móvil.

The discount rates represent the current market assessment of the risks specific to each CGU, taking into
consideration the time value of money and individual risks of the underlying assets that have not been incorporated in the cash flow estimates. The discount rate calculation is based on the specific circumstances of the Company and its operating
segments and is derived from its WACC. The WACC takes into account both debt and equity. The cost of equity is derived from the expected return on investment by América Móvils investors. The cost of debt is based on the interest
bearing borrowings América Móvil is obliged to service. Segment-specific risk is incorporated by applying individual beta factors.

The beta factors are evaluated annually based on publicly available market data.

Market participant assumptions are important because, not only do they include industry data for growth rates, management also assesses how
the CGUs position, relative to its competitors, might change over the forecasted period.

m) Leases

The determination of whether
an agreement is, or contains, a lease is based on the substance of the agreement and requires an evaluation of whether performance of the agreement is dependent on the use of a specific asset and whether the agreement transfers the right of use of
the asset to the Company.



|- | Operating leases
|- | ----------------

Leases under which the lessor retains a significant portion of the
risks and benefits inherent to the ownership of the leased asset are considered operating leases. Payments made under operating lease agreements are charged to results of operations on a straight-line basis over the rental period.



F-21

##### Table of Contents

|- | Finance leases
|- | --------------

Lease agreements that transfer substantially all the risks and benefits
of ownership of the leased assets to the Company are accounted for as finance leases. Accordingly, upon commencement of the lease, the asset, which is classified based on its nature, and associated debt are recorded at the lower of the fair value of
the leased asset or the present value of the lease payments. Finance lease payments are apportioned between the reduction of lease liability and the finance cost so that a constant interest rate is determined on the outstanding liability balance.
Finance costs are charged to results of operations over the life of the agreement.

n) Financial assets and liabilities

Financial assets

Financial assets are
categorized, at initial recognition, as (i) financial assets at fair value through profit or loss, (ii) loans and receivables, (iii) held-to-maturity investments, (iv) available-for-sale financial assets, or as
(v) derivatives designated as hedging instruments in an effective hedge, as appropriate.



|- | Initial recognition and measurement
|- | -----------------------------------

Financial assets are initially recognized at fair
value, plus directly attributable transactions costs, except for financial assets designated upon initial recognition at fair value through profit or loss.



|- | Subsequent measurement
|- | ----------------------

The subsequent measurement of assets depends on their
categorization as either financial assets and liabilities measured at fair value through profit and loss, loans and receivables, held to maturity or available for sale financial assets, or derivatives designated as hedging instruments in an
effective hedge.

Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss include financial assets held for trading and financial assets designated upon initial
recognition at fair value through profit or loss as held for trading if they are acquired for the purpose of selling or repurchasing in the short term. Derivatives, including separated embedded derivatives are also classified as held for trading
unless they are designated as effective hedging instruments as defined in IAS 39. Financial assets at fair value through profit or loss are recorded in the consolidated statement of financial position at fair value with net changes in fair value in
the consolidated statements of comprehensive income in the line of valuation of derivatives, interest cost from labor obligations and other financial items.

Held-to-maturity investments

Held-to-maturity investments are those that the Company has the intent and ability to hold to maturity and are recorded at cost which includes
transaction costs and premiums or discounts related to investment that are amortized over the life of the investment based on its outstanding balance, less any impairment. Interest and dividends on investments classified as held-to-maturity are
included within the interest income.

Available-for-sale financial assets

Available-for-sale financial assets are recorded at fair value, with gains and losses, net of tax, reported in other comprehensive income.
Interest and dividends on investments classified as available-for-sale are included in interest income. The fair value of investments is readily available based on market value. The currency effects of securities available for sale are recognized in
the consolidated statement of comprehensive income in the period in which they occur.

Loans and receivables

Loans and receivables are non-derivative financial instruments with fixed or determinable payments that are not quoted in an active markets.
Loans and receivables with a relevant period (including accounts receivable to



F-22



---

##### Table of Contents

subscribers, distributors and other receivables) are measured at amortized cost using the effective interest method, less any impairment. Interest income is recognized by applying the effective
interest rate, except for accounts receivable from subscribers, distributors and others in the short term, where the recognition of interest would be immaterial.

This category generally applies to accounts receivable from subscribers, distributors and other receivables. For more information on
receivables, refer to Note 5.



|- | Derecognition
|- | -------------

A financial asset (or, where applicable, a part of a financial asset or
part of a group of similar financial assets) is primarily derecognized (i.e. removed from the groups consolidated statement of financial position) when: the rights to receive cash flows from the asset have expired, or the Company has
transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a pass-through arrangement; and either (i) the Company has
transferred substantially all the risks and rewards of the asset, or (ii) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates
if and to what extent it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize
the transferred asset to the extent of the Companys continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights
and obligations that the Company has retained.



|- | Impairment of financial assets
|- | ------------------------------

The Company assesses, at each reporting date, whether
there is any objective evidence that a financial asset or a group of financial assets is impaired. A financial asset or a group of financial assets is deemed to be impaired if, and only if, there is objective evidence of impairment as a result of
one or more events that has occurred after the initial recognition of the asset (an incurred loss event) and that loss event has an impact on the estimated future cash flows of the financial asset or the group of financial assets that can be
reliably estimated. Evidence of impairment may include indications that the debtors or a group of debtors is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will
enter bankruptcy or other financial reorganization and when observable data indicating that there is a measurable decrease in the estimated future cash flows, such as changes in arrears or economic conditions that correlate with defaults.



|Financial | assets carried at amortized cost
|--------- | --------------------------------

For financial assets carried at amortized cost, the
Company first assesses whether objective evidence of impairment exists individually for financial assets that are individually significant, or collectively for financial assets that are not individually significant. If the Company determines that no
objective evidence of impairment exists for an individually assessed financial asset, whether significant or not, it includes the asset in a group of financial assets with similar credit risk characteristics and collectively assesses them for
impairment. Assets that are individually assessed for impairment and for which an impairment loss is, or continues to be, recognized are not included in a collective assessment of impairment.

Financial liabilities

Financial
liabilities are classified into the following categories based on the nature of the financial instruments contracted or issued: (i) financial liabilities measured at fair value, and (ii) financial liabilities



F-23



---

##### Table of Contents

measured at their amortized cost. The Companys financial liabilities include accounts payable to suppliers, deferred revenues, other accounts payable, loans and derivative financial
instruments. Derivative financial instruments are measured at fair value; short- and long-term debt and accounts payable, are accounted for as financial liabilities measured at amortized cost.



|- | Initial recognition
|- | -------------------

All financial liabilities are recognized initially at fair value
and, in the case of loans and borrowings and payables, net of directly attributable transaction costs.



|- | Subsequent measurement
|- | ----------------------

The measurement of financial liabilities depends on their
classification, as described below:



|- | Financial liabilities at fair value through profit or loss
|- | ----------------------------------------------------------

Financial liabilities at
fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition at fair value through profit or loss.

Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category
includes derivative financial instruments entered into by the Company that are not designated as hedging instruments in hedge relationships as defined by IAS 39, Financial Instruments: Recognition and Measurement. Separated
embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments.

Gains or losses
on financial liabilities held for trading are recognized in the consolidated statement of comprehensive income.

Financial liabilities
designated upon initial recognition at fair value through profit or loss are designated at the initial date of recognition, and only if the criteria in IAS 39 are satisfied. América Móvil has not designated any financial liabilities as
fair value liabilities through profit or loss.

Loans and borrowings

After initial recognition, interest bearing loans and borrowings are subsequently measured at amortized cost using the effective interest rate
method. Gains and losses are recognized in the consolidated statement of comprehensive income when the liabilities are derecognized as well as through the effective interest rate (EIR) amortization process.

Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the
EIR. The EIR amortization is included in finance costs in the consolidated statement of comprehensive income.

This category generally
applies to interest-bearing loans and borrowings. For more information refer to Note 16.



|- | Derecognition
|- | -------------

A financial liability is derecognized when the obligation under the
liability is discharged or cancelled, or expires.



F-24



---

##### Table of Contents

When an existing financial liability is replaced by another from the same lender on substantially
different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective
carrying amounts is recognized in the statement of profit or loss.



|- | Offsetting of financial instruments
|- | -----------------------------------

Financial assets and financial liabilities are
offset and the net amount is presented in the consolidated statements of financial position if, and only if there is:



| | (i) | a currently a legally enforceable right to offset the recognized amounts, and
| | --- | -----------------------------------------------------------------------------



| | (ii) | the intention to either settle them on a net basis, or to realize the assets and settle the liabilities simultaneously.
| | ---- | -----------------------------------------------------------------------------------------------------------------------



|- | Fair value of financial instruments
|- | -----------------------------------

At each financial statement reporting date, the
fair value of financial instruments traded in active markets is determined based on market prices, or prices quoted by brokers (purchase price for asset positions and sales price for liability positions), without any deduction for transaction costs.

For financial instruments that are not traded in an active market, the fair value is determined using appropriate valuation techniques.
Such techniques may include using recent arms length market transactions, references to the current fair value of another financial instrument that is substantially similar, a discounted cash flow analysis or other valuation models.

Note 14 provides an analysis of the fair values of the Companys financial instruments.

o) Transactions in foreign currency

Transactions in foreign currency are recorded at the prevailing exchange rate at the time of the related transactions. Foreign currency
denominated assets and liabilities are translated at the prevailing exchange rate at the financial statement reporting date. Exchange differences determined from the transaction date to the time foreign currency denominated assets and liabilities
are settled or translated at the financial statement reporting date are charged or credited to the results of operations.

The exchange
rates used for the translation of foreign currencies against the Mexican peso are as follows:

|(1) | Official exchange rate published by the Argentine Central Bank. The Argentine peso has experienced significant devaluation over the past several years and the government has adopted various rules and regulations since
late 2011 that established new restrictive controls on capital flows into the country. These enhanced exchange controls have practically closed the foreign exchange market to retail transactions. It is widely reported that the Argentine peso/U.S.
dollar exchange rate in the unofficial market substantially differs from the official foreign exchange rate. The Argentine government could impose further exchange controls or restrictions on the movement of capital and take other measures in the
future in response to capital flight or a significant depreciation of the Argentine peso.

|(2) | Includes United States, Ecuador, El Salvador, Puerto Rico and Panama.
|--- | ---------------------------------------------------------------------

p) Accounts payable, accrued
liabilities and provisions

Liabilities are recognized whenever (i) the Company has current obligations (legal or assumed)
resulting from a past event, (ii) when it is probable the obligation will give rise to a future cash disbursement for its settlement, and (iii) the amount of the obligation can be reasonably estimated.

When the effect of the time value of money is significant, the amount of the liability is determined as the present value of the expected
disbursements to settle the obligation. The discount rate is determined on a pre-tax basis and reflects current market conditions at the financial statement reporting date and, where appropriate, the risks specific to the liability. Where
discounting is used, an increase in the liability is recognized as finance expense.

Contingent liabilities are recognized only when it is
probable they will give rise to a future cash disbursement for their settlement. Also, contingencies are only recognized when they will generate a loss.

q) Employee benefits

The Company has
defined benefit pension plans in place for its subsidiaries Radiomóvil Dipsa, S.A. de C.V., Telecomunicaciones de Puerto Rico, S.A., Teléfonos de México and Embratel. Embratel also has medical plans and defined contribution
plans. The Company recognizes the costs of these plans based upon independent actuarial computations, which are determined using the projected unit credit method. The latest actuarial computation was prepared as of December 31, 2013.

Mexico

The Mexican subsidiaries have the
obligation to pay seniority premiums to personnel based on the Mexican Federal labor law, which also establishes the obligation to make certain payments to personnel who cease to provide services under certain circumstances.

The costs of pensions, seniority premiums and severance benefits are recognized based on calculations by independent actuaries using the
projected unit credit method using financial hypotheses, net of inflation.

Puerto Rico

In Puerto Rico, the Company has noncontributing pension plans for full-time employees, which are tax qualified as they meet the Employee
Retirement Income Security Act of 1974 requirements.

The pension benefit is composed of two elements:

(i) An employee receives an annuity at retirement if the employee meets the rule of 85 (age at retirement plus accumulated years of service).
The annuity is calculated by applying a percentage multiplied by the number of years of service to the last three years of salary.



F-26



---

##### Table of Contents

(ii) The second element is a lump-sum benefit based on years of service equivalent to
approximately nine to twelve months of salary. Health care and life insurance benefits are also provided to retirees under a separate plan (post-retirement benefits).

Ecuador

The subsidiary Consorcio
Ecuatoriano de Telecomunicaciones, S.A. has a pension plan, where the Company purchases an annuity for the employee and is paid by the employee by means of individual funding. The Company purchases a deferred annuity from an insurance company for
which the Company pays an annual premium. This plan is classified as a defined benefit plan. The cost of the plan for the period is disclosed in Note 12.

Other subsidiaries

For the rest of the
Companys subsidiaries, there are no defined benefit plans or compulsory defined contribution structures. However, the foreign subsidiaries make contributions to national pension, social security and severance plans in accordance with the
percentages and rates established by the applicable payroll and labor laws of each country. Such contributions are made to the entities designated by the country and are recorded as direct labor benefits in the results of operations as they are
incurred.

Re-measurements of defined benefit plans, comprising of actuarial gains and losses, the effect of the asset ceiling, excluding
net interest and the return on plan assets (excluding net interest), are recognized immediately in the statements of financial position with a corresponding debit or credit to retained earnings through OCI in the period in which they occur.
Re-measurements are not reclassified to profit or loss in subsequent periods.

Past service costs are recognized in profit or loss on the
earlier of:



| | (i) | The date of the plan amendment or curtailment, and
| | --- | --------------------------------------------------



| | (ii) | The date that the Company recognizes restructuring-related costs
| | ---- | ----------------------------------------------------------------

Net interest on liability
for defined benefits is calculated by applying the discount rate to the net defined benefit liability or asset and it is recognized in the valuation of derivatives, interest cost from labor obligations and other financial items in the
consolidated comprehensive income statement. The Company recognizes the changes in the net defined benefit obligation under cost of sales and services and Commercial, administrative and general expenses in the consolidated
statements of comprehensive income.

Paid absences

The Company recognizes a provision for the costs of paid absences, such as vacation time, based on the accrual method.

r) Employee profit sharing

Employee
profit sharing is paid by certain subsidiaries of the Company to its eligible employees. In Mexico, the employee profit sharing is computed at the rate of 10% of the individual company taxable income, except for depreciation of historical rather
than restated values, and foreign exchange gains and losses, which are not included until the asset is disposed of or the liability is due and other effects of inflation are also excluded. Current year employee profit sharing is presented as an
operating expense in the consolidated statements of comprehensive income.

s) Income taxes

Current income tax is presented as a short-term liability, net of prepayments made during the year.

Deferred income tax is determined using the liability method based on the temporary differences between the tax values of the assets and
liabilities and their book values at the financial statement reporting date.



F-27



---

##### Table of Contents

Deferred tax assets and liabilities are measured using the tax rates that are expected to be in
effect in the period when the asset will materialize or the liability will be settled, based on the enacted tax rates (and tax legislation) that have been enacted or substantially enacted at the financial statement reporting date. The value of
deferred tax assets is reviewed by the Company at each financial statement reporting date and is reduced to the extent that it is more likely than not that the Company will not have sufficient future tax profits to allow for the realization of all
or a part of its deferred tax assets. Unrecognized deferred tax assets are revalued at each financial statement reporting date and are recognized when it is more likely than not that there will be sufficient future tax profits to allow for the
realization of these assets.

Deferred taxes relating to items recognized outside profit or loss are also recognized outside of profit and
loss. These deferred taxes are recognized together with the underlying transaction in other comprehensive income.

Deferred tax
consequences on unremitted foreign earnings are accounted for as temporary differences, except to the extent that the Company is able to control the timing of the reversal of the temporary difference, and it is probable that the temporary difference
will not reverse in the foreseeable future. Taxes paid on remitted foreign earnings are able to be offset against Mexican taxes, thus to the extent that a remittance is to be made, the deferred tax would be limited to the incremental difference
between the Mexican tax rate and the rate of the remitting country. As of December 31, 2012 and 2013, the Company has not provided for any deferred taxes related to unremitted foreign earnings.

The Company offsets tax assets and liabilities if and only if it has a legally enforceable right to set off current tax assets and current tax
liabilities and the deferred tax assets and deferred tax liabilities relate to income taxes levied by the same tax authority.

t) Sales tax

Revenues, expenses and assets are recognized net of the amount of sales tax, except:



| |  |  | When the sales tax incurred on a purchase of assets or services is not recoverable from the taxation authority, in which case, the sales tax is recognized as part of the cost of acquisition of the asset or as part of
the expense item, as applicable.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Receivables and payables that are stated with the amount of sales tax included.
| | - |  | -------------------------------------------------------------------------------

The net
amount of sales tax recoverable from, or payable to, the taxation authority is included as part of receivables or payables in the statements of financial position.

u) Advertising

Advertising expenses are
expensed as incurred. For the years ended December 31, 2011, 2012 and 2013, advertising expenses were Ps.17,867,455, Ps.22,652,826 and Ps.19,699,228, respectively, and are recorded in the consolidated statements of comprehensive income in the
line Commercial, administrative and general expenses.

v) Earnings per share

Basic and diluted earnings per share are determined by dividing net income for the year by the weighted-average number of shares outstanding
during the year (the common control component of the shares are reflected for all periods presented). In determining the weighted average number of shares issued and outstanding, shares repurchased by the Company have been excluded.

w) Financial risks

The main risks
associated with the Companys financial instruments are: (i) liquidity risk, (ii) market risk (foreign currency exchange risk and interest rate risk) (iii) credit risk and counterparty risk. The Board of Directors approves the
policies submitted by management to mitigate these risks.

##### Table of Contents

(i) Liquidity risk

Liquidity risk is the risk that the Company may not meet its financial obligations associated with financial instruments when they are due. The
Companys financial obligations and commitments are included in Notes 16 and 17.

(ii) Market risk

The Company is exposed to market risks from changes in interest rates and fluctuations in exchange rates of foreign currencies. The
Companys debt is denominated in foreign currencies, mainly in US dollars, other than its functional currency. In order to reduce the risks related to fluctuations in the exchange rate of foreign currencies, the Company uses derivative
financial instruments such as cross-currency swaps and forwards to adjust exposures resulting from foreign exchange currency. The Company does not use derivatives to hedge the exchange risk arising from having operations in different countries.

Additionally, the Company occasionally uses interest rate swaps to adjust its exposure to the variability of the interest rates or to reduce
its financing costs. The Companys practices vary from time to time depending on its judgments about the level of risk, expectations of change in the movements of interest rates and the costs of using derivatives. The Company may terminate or
modify a derivative financial instrument at any time. See Note 11 for disclosure of the fair value of derivatives as of December 31, 2012 and 2013.

(iii) Credit risk

Credit risk represents the
loss that could be recognized in case the counterparties fail to fully comply with the contractual obligations.

The financial instruments
that potentially represent concentrations of credit risk are cash and short-term deposits, trade accounts receivable and financial instruments related to debt and derivatives. The Companys policy is designed in order to limit its exposure to
any one financial institution; therefore, the Companys financial instruments are contracted with several different financial institutions located in different geographic regions.

The credit risk in accounts receivable is diversified because the Company has a broad customer base that is geographically dispersed. The
Company continuously evaluates the credit conditions of its customers and does not require collateral to guarantee collection of its accounts receivable. The Company monitors on a monthly basis its collection cycle to avoid deterioration of its
results of operations.

A portion of the Companys cash surplus is invested in short-term deposits with financial institutions with
high credit ratings.

(iv) Sensitivity analysis for market risks

The Company uses sensitivity analyses to measure the potential losses based on a theoretical increase of 100 basis points in interest rates and
a 10% fluctuation in exchange rates:

a) Exchange rate fluctuations

Should the Companys debt at December 31, 2013 of Ps.490,319,844 suffer a 10% increase in exchange rates, the debt would increase by
Ps.48,566,612 (resulting in total debt of Ps.538,886,456), while the Companys net interest expense would increase by Ps.2,113,199 as a consequence of the base for interest being higher in Mexican pesos.

b) Interest rates

In the event
that the Companys agreed-upon interest rates at December 31, 2013 increased by 100 basis points, the increase in net interest expense would be Ps.4,506,326.

##### Table of Contents

(v) Concentration of risk

The Company depends on several key suppliers and sellers. During the years ended December 31, 2011, 2012 and 2013, approximately 58%, 55%
and 64%, respectively, of the total cost of the cellular equipment of América Móvil represent purchases made from three suppliers, and approximately 29%, 20% and 21%, respectively, of the telephony plant equipment was purchased from
two suppliers. If any of these suppliers were to cease to provide equipment and services to the Company, or to provide them in a timely manner and at a reasonable cost, the Companys business and results of operations might be adversely
affected.

(vi) Administration of capital

The Company manages its capital to ensure that its subsidiaries continue as going concerns while maximizing the return to stakeholders through
the optimization of their balances and debt capital to maintain the lowest cost of capital available. The Company manages its capital structure and makes adjustments according to economic conditions. To maintain its capital structure the Company may
adjust the dividend payment to shareholders or buy back shares, for which the company holds a reserve. In addition, the Company creates a legal reserve, as required by law. See Note 19.

x) Derivative financial instruments

The
Company is exposed to interest rate and foreign currency risks, which it tries to mitigate through a controlled risk management program that includes the use of derivative financial instruments. The Company principally uses cross-currency swaps and,
if necessary, foreign currency forwards to offset the short-term risk of exchange rate fluctuations. For purposes of reducing the risks from changes in interest rates, the Company utilizes interest rate swaps through which it pays or receives the
net amount resulting from paying or receiving a fixed rate, and from receiving or paying cash based on a variable rate, on notional amounts denominated mainly in Mexican pesos, U.S. dollars, Japanese yen, Swiss francs, Euros and Sterling pounds. At
December 31, 2011, 2012 and 2013, some of the Companys derivative financial instruments have been designated, and have qualified, as cash flow hedges.

The policy of the Company in this regard comprises: (i) the formal documentation of all transactions between the hedging instruments and
hedged positions, (ii) risk management objectives, and (iii) the strategy for executing hedging transactions. This documentation also includes the relationship between the cash flows of the derivatives with those of the Companys
assets and liabilities recognized in the consolidated statement of financial position.

The effectiveness of the Companys
derivatives is evaluated prior to their designation as hedges, as well as during the hedging period, which is performed at least quarterly based on recognized statistical techniques. Whenever it is determined that a derivative is not highly
effective as a hedge or that the derivative ceases to be a highly effective hedge, the Company ceases to apply hedge accounting for the derivative on a prospective basis.

Derivative financial instruments are recognized in the consolidated statement of financial position at fair value, which is obtained from the
financial institutions with which the agreements are entered into, and it is the Companys policy to compare such fair value to the valuation provided by an independent pricing provider retained by the Company. The effective portion of gains or
losses on the cash flow derivatives is recognized in equity under the heading Effect for fair value of derivatives, and the ineffective portion is charged to results of operations for the period. Changes in the fair value of derivatives
that do not qualify as hedging instruments are recognized immediately in results.

The change in fair value recognized in results of
operations corresponding to derivatives that qualify as hedges is presented in the same caption of the consolidated statements of comprehensive income as the gain or loss of the hedged item (interests and foreign exchange rate).

y) Presentation of consolidated statement of comprehensive income

The costs and expenses shown in América Móvils consolidated statement of comprehensive income are presented in combined
manner (based on both their function and nature), which allows for a better understanding of the components of the Companys operating income. This classification allows for a comparison to the telecommunications industry.

The Companys presents operating income in its consolidated statements of comprehensive income, since it is a key indicator of the
Companys performance. Operating income includes operating revenues, operating costs and expenses.

z) Operating segments

Segment information is presented based on information used by management in its decision-making processes. Segment information is presented
based on the geographic areas in which the Company operates.

The management of América Móvil is responsible for making
decisions regarding the resources to be allocated to the Companys different segments, as well as evaluating the performance of each segment.

Inter-segment revenues are eliminated upon consolidation and reflected in the eliminations column.

None of the segments records revenue from transactions with a single external customer amounting to at least 10% or more of the Companys
revenues.

z.1) Convenience translation

At December 31, 2013, amounts in U.S. dollars have been included in the financial statements solely for the convenience of the reader and
have been translated to Mexican pesos at December 31, 2013 at an exchange rate of Ps.13.0765 pesos per U.S. dollar, which was the exchange rate at that date. Such translation should not be construed as a representation that the Mexican peso can
be converted to U.S. dollars at the exchange rate in effect on December 31, 2013 or any other exchange rate.

z.2) Judgments, estimates and
significant accounting assumptions

In preparing its consolidated financial statements, América Móvil makes estimates
concerning a variety of matters. Some of these matters are highly uncertain, and its estimates involve judgments it makes based on the information available to it. In the discussion below, América Móvil has identified several of these
matters for which its financial statements would be materially affected if either (1) América Móvil used different estimates that it could reasonably have used or (2) in the future América Móvil changes its
estimates in response to changes that are reasonably likely to occur.

The following discussion addresses only those estimates that
América Móvil considers most important based on the degree of uncertainty and the likelihood of a material impact if it used a different estimate. There are many other areas in which América Móvil uses estimates about
uncertain matters, but the reasonably likely effect of changed or different estimates is not material to the financial presentation.

Fair Value of
Financial Assets and Liabilities

América Móvil has substantial financial assets and liabilities that it recognizes at
their fair value, which is an estimate of the amount at which the instrument could be exchanged in a current transaction between willing parties. The methodologies and assumptions América Móvil uses to estimate an instruments
fair value depend on the type of instrument and include (i) recognizing cash and cash equivalents and trade receivables and trade payables and other current liabilities at close to their carrying amount, (ii) recognizing quoted instruments
at their price quotations on the reporting date, (iii) recognizing unquoted instruments, such as loans from banks and obligations under financial leases, by discounting future cash flows using rates for similar instruments and



F-31

##### Table of Contents

(iv) applying various valuation techniques, such as present value calculations, to derivative instruments. Using different methodologies or assumptions to estimate the fair value of
AMXs financial assets and liabilities could materially impact the reported financial results. See Note 14.

Estimated Useful Lives of Plant,
Property and Equipment

América Móvil estimates the useful lives of particular classes of plant, property and equipment
in order to determine the amount of depreciation expense to be recorded in each period. América Móvil currently depreciates most of its telephone plant and equipment based on an estimated useful life determined upon the expected
particular conditions of operations and maintenance in each of the countries in which it operates. The estimates are based on AMXs historical experience with similar assets, anticipated technological changes and other factors, taking into
account the practices of other telecommunications companies. América Móvil reviews estimated useful lives each year to determine whether they should be changed, and at times, it changes them for particular classes of assets.
América Móvil may shorten the estimated useful life of an asset class in response to technological changes, changes in the market or other developments. This results in increased depreciation expense. See Notes 2j and Note 8.

Impairment of Long-Lived Assets

América Móvil has large amounts of long-lived assets, including property, plant and equipment, intangible assets, investments in
affiliates and goodwill, on its balance sheet. América Móvil is required to test long-lived assets for impairment when circumstances indicate a potential impairment or, in some cases, at least on an annual basis. The impairment
analysis for long-lived assets requires the Company to estimate the recovery value of the asset, which is the higher of its fair value (minus any disposal costs) and its value in use. To estimate the fair value of a long-lived asset, América
Móvil typically takes into account recent market transactions or, if no such transactions can be identified, América Móvil uses a valuation model that requires the making of certain assumptions and estimates. Similarly, to
estimate the value in use of long-lived assets, América Móvil typically makes various assumptions about the future prospects for the business to which the asset relates, consider market factors specific to that business and estimate
future cash flows to be generated by that business. Based on this impairment analysis, including all assumptions and estimates related thereto, as well as guidance provided by IFRS relating to the impairment of long-lived assets, América
Móvil determines whether it needs to take an impairment charge to reduce the net carrying value of the asset as stated on its balance sheet. Assumptions and estimates about future values and remaining useful lives are complex and often
subjective. They can be affected by a variety of factors, including external factors, such as industry and economic trends, and internal factors, such as changes in the Companys business strategy and its internal forecasts. Different
assumptions and estimates could materially impact the Companys reported financial results. More conservative assumptions of the anticipated future benefits from these businesses could result in impairment charges, which would decrease net
income and result in lower asset values on the balance sheet. Conversely, less conservative assumptions could result in smaller or no impairment charges, higher net income and higher asset values. The key assumptions used to determine the
recoverable amount for the Companys CGUs, are further explained in Notes 2 l and Note 9 and Note 10.

Deferred Taxes

América Móvil is required to estimate its income taxes in each of the jurisdictions in which it operates. This process involves
the jurisdiction-by-jurisdiction estimation of actual current tax exposure and the assessment of temporary differences resulting from the differing treatment of certain items, such as accruals and amortization, for tax and financial reporting
purposes, as well as net operating loss carry-forwards and other tax credits. These items result in deferred tax assets and liabilities, which are included in the América Móvils consolidated statement of financial position.
América Móvil assess in the course of its tax planning procedures the fiscal year of the reversal of its deferred tax assets and liabilities, and if there will be future taxable profits in those periods to support the recognition of
the deferred tax assets. Significant management judgment is required in determining



F-32



---

##### Table of Contents

the Companys provisions for income taxes, deferred tax assets and liabilities. The analysis is based on estimates of taxable income in the jurisdictions in which América Móvil
operates and the period over which the deferred tax assets and liabilities will be recoverable or settled. If actual results differ from these estimates, or América Móvil adjusts these estimates in future periods, its financial
position and results of operations may be materially affected.

América Móvil records deferred tax assets based on the
amount that it believes is probable to be realized. In assessing the future realization of deferred tax assets, the Company considers future taxable income and ongoing tax planning strategies. In the event that the estimates of projected future
taxable income and benefits from tax planning strategies are lowered, or changes in current tax regulations are enacted that would impose restrictions on the timing or extent of the ability to utilize the tax benefits of net operating loss
carry-forwards in the future, an adjustment to the recorded amount of deferred tax assets would be made, with a related charge to income. See Note 20.

Accruals

Accruals are recorded when, at
the end of the period, the Company has a present obligation as a result of past events, whose settlement requires an outflow of resources that is considered probable and can be measured reliably. This obligation may be legal or constructive, arising
from, but not limited to, regulation, contracts, common practice or public commitments, which have created a valid expectation for third parties that the Company will assume certain responsibilities. The amount recorded is the best estimation
performed by the Companys management in respect of the expenditure that will be required to settle the obligations, considering all the information available at the date of the financial statements, including the opinion of external experts,
such as legal advisors or consultants. Accruals are adjusted to account for changes in circumstances for ongoing matters and the establishment of additional accruals for new matters.

If América Móvil is unable to reliably measure the obligation, no accrual is recorded and information is then presented in the
notes to its consolidated financial statements. Because of the inherent uncertainties in this estimation, actual expenditures may be different from the originally estimated amount recognized. See Note 13.

América Móvil is subject to various claims and contingencies related to tax, labor and legal proceedings as described in Note
17.

Labor Obligations

América Móvil recognizes liabilities on its balance sheet and expenses in its comprehensive income statement to reflect its
obligations related to its post-retirement seniority premiums, pension and retirement plans in the countries in which it operates and offer defined contribution and benefit pension plans. The amounts the Company recognizes are determined on an
actuarial basis that involves many estimates and accounts for post-retirement and termination benefits in accordance with IFRS.

América Móvil uses estimates in four specific areas that have a significant effect on these amounts: (a) the rate of return
América Móvil assumes its pension plan will achieve on its investments, (b) the rate of increase in salaries that the Company assumes it will observe in future years, (c) the discount rates that the Company uses to calculate
the present value of its future obligations and (d) the expected rate of inflation. The assumptions América Móvil has applied are further disclosed in Note 12. These estimates are determined based on actuarial studies
performed by independent experts using the projected unit-credit method.

Allowance for Doubtful Accounts

América Móvil maintains an allowance for doubtful accounts for estimated losses resulting from the failure of its customers,
distributors and cellular operators to make required payments. The Company bases these



F-33



---

##### Table of Contents

estimates on the individual conditions of each of the markets in which it operates that may impact the collectability of accounts. In particular, in making these estimates the Company takes into
account (i) with respect to accounts with customers, the number of days since the calls were made, (ii) with respect to accounts with distributors, the number of days invoices are overdue and (iii) with respect to accounts with
cellular operators, both the number of days since the calls were made and any disputes with respect to such calls. The amount of loss, if any, that América Móvil actually experiences with respect to these accounts may differ from the
amount of the allowance maintained in connection with them. See Note 5.

3. New standards, interpretations and amendments thereof

During 2013, the Company applied, for the first time, certain new IFRS amendments that required retrospective application (restatement) of the
previously reported financial statements. Most specifically, the Company adopted IAS 1 and IAS 19 (Revised 2011), both as quantified below. Several other new standards and amendments were also applied for the first time in 2013. However, the
adoption of those IFRS standards and amendments did not have a significant impact on the financial statements of América Móvil.

The nature and the impact of each new standard/amendment are described below.

IAS 1 Presentation of Items of other comprehensive Income Amendments to IAS 1

The amendments to IAS 1 introduce a grouping of items presented in other comprehensive income (OCI). Items that could be
reclassified (or recycled) to profit or loss at a future point in time (e.g., net gain on hedge of net investment, effect of translation, net movement on cash flow hedges and net loss or gain on available-for-sale financial assets) now have to be
presented separately from items that will never be reclassified (e.g., remeasurement of actuarial gains and losses on defined benefit plans). The amendment affected presentation only and had no impact on América Móvils financial
position or results of operations. Refer to the consolidated statement of other comprehensive income for a quantification of this new segregation for the periods presented herein.

IAS 1 Clarification of the requirement for comparative information (Amendment)

The amendment to IAS 1 clarifies the difference between voluntary additional comparative information and the minimum required comparative
information. An entity must include comparative information in the related notes to the financial statements when it voluntarily provides comparative information beyond the minimum required comparative period. The additional voluntarily comparative
information does not need to be presented in a complete set of financial statements.

An opening statement of financial position (known as
the third balance sheet) must be presented when an entity applies an accounting policy retrospectively, makes retrospective restatements, or reclassifies items in its financial statements, provided any of those changes has a material
effect on the statement of financial position at the beginning of the preceding period. The opening consolidated statement of financial position of the earliest comparative period presented (January 1, 2012) and the comparative figures have been
accordingly restated. The amendment clarifies that a third balance sheet does not have to be accompanied by comparative information in the related notes.

IAS 19, Employee Benefits (Revised)

IAS 19R includes a number of amendments to the accounting for defined benefit plans, including actuarial gains and losses that are now
recognized in OCI and permanently excluded from profit and loss. Expected returns on plan assets are no longer recognized in profit or loss; instead, there is a requirement to recognize interest on the net defined benefit liability (asset) in profit
or loss, calculated using the discount rate used to measure the defined benefit obligation and; Unvested past service costs are now recognized in profit or loss at the earlier of when the amendment occurs or when the related restructuring or
termination costs are recognized. Other amendments include new disclosures, such as, quantitative sensitivity disclosures.

These
modifications were effective beginning January 1, 2013, with retrospective application to January 1, 2011 resulting in the restatement of both the December 31, 2012 consolidated statement of financial position, and the previously
reported consolidated statement of comprehensive income for the years 2012 and 2011.

Changes in the defined benefit obligation and plan
assets are divided in three components:



| | (i) | Current service cost,
| | --- | ---------------------



| | (ii) | Net interest of net (assets) liabilities of defined benefits, (finance cost over the net obligation for defined benefits and expected return on the plan assets), and
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | Actuarial gains and losses (remeasurements) of the net (assets) liabilities for defined benefits.
| | ----- | -------------------------------------------------------------------------------------------------

The net interest of net (assets) liabilities is calculated using a rate of return for high quality corporate bonds for the Companys
Puerto Rico operations, using a rate of return for Mexican Government bonds for the Companys Mexican operations, and using a rate of return for Brazilian Government bonds for the Companys Brazilian operations. The modifications require
that interest on plan assets is calculated with the discount rate used to measure the obligation, which may be less than the rate previously used to calculate the expected return on plan assets.

In the case of AMX, the transition to IAS 19R had an impact on the pension asset and employee benefits as is explained in the table below:

The adoption of IAS 19R had no impact on previously reported amounts of cash flows from operating, financing or investing
activities

IFRS 10 Consolidated Financial Statements and IAS 27 Separate Financial Statements

IFRS 10 establishes a single control model that applies to all entities including special purpose entities. IFRS 10 replaces the parts of
previously existing IAS 27, Consolidated and Separate Financial Statements that dealt with consolidated financial statements and SIC-12, ConsolidationSpecial Purpose Entities. IFRS 10 changes the
definition of control such that an investor controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. To meet
the definition of control in IFRS 10, all three criteria must be met, including: (a) an investor has power over an investee; (b) the investor has exposure, or rights, to variable returns from its involvement with the investee; and
(c) the investor has the ability to use its power over the investee to affect the amount of the investors returns. IFRS 10 was adopted on January 1, 2013 and in accordance with the transitional provisions the Company reassessed the
control conclusion for its investees as at January 1, 2013 and it had no impact on the Companys consolidated financial statements.

IFRS 11
Joint Arrangements and IAS 28 Investment in Associates and Joint Ventures

IFRS 11 replaces IAS 31, Interests in Joint Ventures and
SIC-13 Jointly-controlled EntitiesNon-monetary Contributions by Ventures. IFRS 11 removes the option to account for jointly controlled entities (JCEs) using proportionate consolidation. Instead, JCEs that meet the
definition of a joint venture under IFRS 11 must be accounted for using the equity method.

IFRS 11 was effective for annual periods
beginning on or after January 1, 2013. The Company reassessed its involvement in its joint arrangements and concluded that the adoption of this standard had no impact on the Companys consolidated financial statements.

IFRS 12 Disclosure of Interests in Other Entities

IFRS 12 sets out the requirements for disclosures relating to an entitys interests in subsidiaries, joint arrangements, associates and
structured entities. The requirements in IFRS 12 are more comprehensive than the previously existing disclosure requirements for subsidiaries. For example, additional disclosures are required when a subsidiary is controlled with less than a majority
of voting rights. While the Company has subsidiaries with material non-controlling interests, there are no unconsolidated structured entities. The Company has provided the applicable disclosures in Note 10.

IFRS 13 Fair Value Measurement

IFRS 13 establishes a single source of guidance under IFRS for all fair value measurements. IFRS 13 does not change when an entity is required
to use fair value, but rather provides guidance on how to measure fair value under IFRS when fair value is required or permitted. The application of IFRS 13 has not materially impacted the fair value measurements carried out by the Company.

IFRS 13 also requires specific disclosures on fair values, some of which replace existing disclosure requirements in other standards,
including IFRS 7, Financial Instruments: Disclosures. Some of these disclosures are specifically required for financial instruments by IAS 34.16A(j), thereby affecting the financial statements. The Company has provided the
applicable disclosures in Note 14.

Standards issued but not yet effective and annual improvements

The Company has not early adopted any other IFRS interpretation or amendment that has been issued but is not yet effective.

The standards and interpretations that are issued, but not yet effective, up to the date of issuance of the Companys financial
statements are disclosed below. The Company intends to adopt these standards, if applicable, when they become effective.

IFRS 9 Financial Instruments

IFRS 9, as issued, reflects the first phase of the IASBs work on the replacement of IAS 39 and applies to classification and
measurement of financial assets and financial liabilities as defined in IAS 39. The standard was initially effective for annual periods beginning on or after January 1, 2013, but amendments to IFRS 9 Mandatory Effective Date and Transition
Disclosures, issued in December 2011, moved the mandatory effective date to January 1, 2015. In subsequent phases, the IASB will address hedge accounting and impairment of financial assets. The adoption of the first phase of IFRS 9 will have an
effect on the classification and measurement of the Companys financial assets, but will not have an impact on the classification and measurements of the Companys financial liabilities. The Company will quantify the effect in conjunction
with the other phases, when the final standard including all phases is issued.

IAS 32 Offsetting Financial Assets and Financial
LiabilitiesAmendments to IAS 32

These amendments clarify the meaning of currently has a legally enforceable right to
set-off and the criteria for non-simultaneous settlement mechanisms of clearing houses to qualify for offsetting. These are effective for annual periods beginning on or after January 1, 2014. The Company has yet to quantify the impact of
these amendments.

IFRIC Interpretation 21 Levies (IFRIC 21)

IFRIC 21 clarifies that an entity recognizes a liability for a levy when the activity that triggers payment, as identified by the relevant
legislation, occurs. For a levy that is triggered upon reaching a minimum threshold, the interpretation clarifies that no liability should be anticipated before the specified minimum threshold is reached. IFRIC 21 is effective for annual periods
beginning on or after January 1, 2014. The Company has yet to quantify the impact of this standard on its financial statements.

IAS 39 Novation
of Derivatives and Continuation of Hedge AccountingAmendments to IAS 39

These amendments provide relief from discontinuing hedge
accounting when novation of a derivative designated as a hedging instrument meets certain criteria. These amendments are effective for annual periods beginning on or after January 1, 2014. The Company has not novated its derivatives during
2013. However, these amendments would be considered for future novations.

IAS 36 Recoverable Amount Disclosures for Non-Financial AssetsAmendments to IAS 36

These amendments require disclosure of the recoverable amounts of the assets or CGUs for which an impairment loss has been recognized or
reversed during the period. The amendments are effective retrospectively for annual periods beginning on or after January 1, 2014. The Company has not recognized or reversed any impairment loss on non-financial assets during the periods
presented in these financial statements.

Annual Improvements to IFRSs2010-2012 Cycle and 2011-2013 Cycle

On December 12, 2013, the IASB issued two cycles of Annual Improvements to IFRSsCycles 2010-2012 and 2011-2013that contain 11
changes to nine standards: IFRS 1 First-time Adoption of International Financial Reporting Standards; IFRS 2 Share-based Payment; IFRS 3 Business Combinations; IFRS 8 Operating Segments; IFRS 13 Fair Value Measurement; IAS 16 Property, Plant and
Equipment; IAS 24 Related Party Disclosures; IAS 38 Intangible Assets; and IAS 40 Investment Property. One of the amendments to IFRS 13 and the amendment to IFRS 1 only affect the Basis for Conclusions for the respective standards and, therefore,
are effective immediately. The other amendments are effective from July 1, 2014 either prospectively or retrospectively. The Company has yet to quantify the impact these annual improvements will have on its financial statements.

2011 Acquisitions

i) During the first quarter of 2011, the Company won a public bid to provide mobile telecommunications services on a nationwide level in Costa
Rica. The concession obtained by its subsidiary grants the Company the right to use and exploit the 70Mhz frequency range for a term of 15 years. The upfront amount paid was Ps.926,000 and no further payments need to be made.

ii) As part of the business combination of Digicel Group Limited described in Note 10, América Móvil recognized a license for an

2012 Acquisitions

i) In January 2012, Telmex Colombia acquired a new TV license for a period of 8 years, expiring in 2020. The amount paid was Ps.253,927.

ii) As part of the business combination of Net Serviços de Comunicação, S.A, the Company recognized a license for an
amount of Ps.12,414,914. Given recent changes in the telecommunications law, licenses in Brazil can be renewed indefinitely at nominal cost. Thus, these licenses are considered as indefinite life intangible and are not amortized.

the following states of Brazil: Acre, Rondonia, Tacantins, Bahia, Paraná, Santa Catarina, Rio de Janeiro, Espíritu Santo, Sao Paulo, Amazonas, Maranha, Roraima, Amapá and Pará. Such licenses expire in October 2027.

Also Claro Brazil acquired licenses related to 4G (fourth generation) services, or broadband of 2,500 MHz to provide 4G services in Brazilian
territory, except for the Brazilian state of Amazonas. Such licenses expire between June 2014 and October 2027.

Additionally, the

2013 Acquisitions

b) The following is a description of the major acquisitions of investments in associates and subsidiaries
during the years ended December 31, 2011, 2012 and 2013:

Acquisitions 2011

i) Net Serviços de Comunicação, S.A. (NET)

In 2011, the Company accounted for its holdings in NET using the equity method of accounting given that it did not exercise voting control over
NET. During 2012, given a change in the Brazilian telecommunications laws, the Company was able to exercise an option whereby it obtained control and began consolidating NET starting January 1, 2012.

In 2010, Embratel purchased 155,415,666 preferred shares, no par value, of NET through a public offer. A sufficient number of preferred shares
were tendered into the offer to give rise to a shareholder put right at the offer price adjusted for inflation through settlement of the put. The period for exercising the shareholder put right expired on January 13, 2011. A total of 49,847,863
preferred shares, equivalent to 21.81% of outstanding preferred shares as of October 13, 2010, were tendered during the shareholder put right period, bringing the final number of preferred shares tendered into the offer to 193,701,299. The
total purchase price of all preferred shares acquired pursuant to the tender offer was approximately R$4.3 billion (Ps.31,525,000 at the exchange rate as of January 13, 2011) paid in cash.

At December 31, 2011, América Móvil through Embrapar and Embratel had a shareholding (direct and indirect) of 87.5% in NET.

The following tables show condensed consolidated financial information for NET for the year ended December 31, 2011:

ii) Star One S.A.

In July 2011, Embratel acquired a 20% interest in Star One S.A. (Star One) from GE Satellite Holdings LLC and its affiliates for a
total purchase price of Ps.2,716,164 (US$235,000). Star One is a Brazilian company that provides satellite services in Brazil. Prior to that date, Embratel owned the remaining 80% interest in Star One. Accordingly, since July 2011 Embratel owns 100%
of the shares.

iii) Digicel Group Limited

In November 2011, América Móvil acquired 100% of Digicel Group Limited and its affiliates (Digicel) operations
in Honduras and sold its operations in Jamaica to Digicel. The net amount paid was Ps.4,733,385. As part of the acquisition, the identified licenses in the cellular industry were Ps.1,149,112.

Acquisitions 2012

i) Acquisition of Control
over NET

On January 26, 2012, the National Telecommunications Agency of Brazil expressed its consent to the transfer of control
of NET. This authorization then allowed Embrapar to exercise a call option on the shares held by GB Empreendimentos e Participaçoes SA (GB), a company that previously controlled NET, which until that time was controlled by Globo
Cominicação e Particpaçoes S.A. (Globo). Once this option was exercised, Embrapar and its subsidiary Embratel would have voting control of NET. The ability to exercise the option resulted in the Company effectively
controlling NET.

On March 5, 2012 Embrapar exercised the option and purchased ordinary shares of GB. The acquired shares represented
5.5% of the ordinary shares and Embrapar reached 54.54% in the voting capital of GB. As a result of this transaction, América Móvil held an equity interest (directly and indirectly) in NET of 88.0%.

América Móvil obtained control of NET, in accordance with IFRS 3, Business combinations, and recognized the fair value of
NETs assets acquired, liabilities assumed and its non-controlling interest. As part of the business combination, América Móvil derecognized its equity method investment in NET. The difference between the carrying value and the
acquisition date fair value of the equity method investment in NET that was derecognized was not material and accordingly, no gain or loss was recognized.

NETs operating results were consolidated in the statement of comprehensive income beginning January 1, 2012.

The amounts of revenue and net profit of NET recorded in the Companys 2012 and consolidated

ii) KoninKlijke KPN N.V.
(KPN).

On May 29, 2012, AMOV Europa B.V. (AMOV), a wholly-owned subsidiary of América
Móvil, commenced a partial tender offer in cash to all holders of ordinary shares of Koninklijke KPN N.V. (KPN). KPN is the leading telecommunications service provider in the Netherlands, which offers fixed-line and wireless
telecommunications services, internet and Pay TV to consumers, and end-to-end telecommunications services to business customers. AMOV offered to purchase up to the number of shares that would result in AMOV and América Móvil holding
393,283,000 shares (representing a total of up to approximately 27.7% of all outstanding shares of KPN). The offer expired on June 27, 2012, and more than a sufficient number of shares needed for us to reach the maximum ownership amount of
27.7% of the outstanding shares was tendered. Upon closing of the tender offer, the total aggregate cost of the Companys investment in KPN was approximately 3,047 million (Ps.52,200,000).

During April 2013, KPN launched a rights offering to raise up to 3,000 billion of equity. Pursuant to the Companys agreement with
KPN, the Company subscribed for new shares in the rights offering in proportion to the Companys previous ownership of KPN shares. Upon settlement of the offering on May 17, 2013, the Company paid 895.8 million (Ps.14,200,000)
and owned a total of 1,267,677,000 shares of KPN, continuing to represent 29.7% of the outstanding shares of KPN.

In August and November
2013, the Company received dividends for an amount of Ps.88,461 and Ps.123,932, respectively.

In November 2013, the Company sold shares
of KPN representing 2.38% of KPNs outstanding shares for an amount of Ps. 4.3 billion. At December 31, 2012 and 2013, the Company held 29.77% and 27.39% of the outstanding shares of KPN.

Since April 2013, the Company has had two representatives on KPNs Supervisory Board of a total of at least five and no more than nine
members. On August 9, 2013, the Company announced its intention to make a tender offer in cash for all of KPNs ordinary shares that it does not already own (the Intended KPN Offer) at a price of 2.40 per share. On
August 29, 2013, the KPN Preference Shares B Foundation (Stichting Preferente Aandelen B KPN or the KPN Foundation), an independent legal entity with the statutory goal of protecting KPNs interests (which includes the
interests of stakeholders, such as customers, shareholders and employees), exercised a call option in respect of securities of KPN. As a result, the KPN Foundation holds preferred shares of KPN representing 50% of the voting shares less one share,
making América Móvils goal of acquiring more than 50% of the voting rights for KPN unachievable. On October 16, 2013, the Company announced that the Company would not launch the Intended KPN Offer.

América Móvils interest in KPN is accounted for using the equity method in
the consolidated financial statements because although the voting rights of the Company were reduced to 14.9%, its economic interests remained at 29.77% and the Company kept its two seats on the Supervisory Board which is greater than 20% of Board
representation, which is ultimately responsible for all decision-making. Summarized financial information of the associate, based on its IFRS financial information (adjusted for the Companys basis in such investee) is set out below:

As discussed in Note 2 b) ii), the Companys policy is to evaluate at each reporting date whether there
is any objective evidence that an investment in an associate is impaired. If there is a potential impairment, the Company calculates the amount of impairment loss as the difference between the recoverable amount of the associate and its carrying
value, and recognizes the impairment loss in its share of profit or loss of the associate in the consolidated statement of comprehensive income.

The Company owned 422,559,000 and 1,169,797,301 shares of KPN, with a carrying value of Ps.55,007,474 and Ps 69,232,297 as of
December 31, 2012 and 2013, respectively. KPNs shares are traded on the Amsterdam Stock Exchange, and the closing price for such shares was 3.53 and 2.34 per share at December 31, 2012 and 2013, respectively,
equating to a Level 1 fair value of the Companys investment in KPN of Ps.22,600,000 and Ps.49,255,640 at December 31, 2012 and 2013 exchange rates. As of December 31, 2012

and 2013, the carrying value of the investment in KPN was Ps.28,000,000 and Ps.19,976,657, respectively, in excess of its Level 1 fair value. The Level 1 fair value of KPN was Ps.17,048,815 as of
April 25, 2014. Under IAS 39, either a significant or a prolonged decline of the Level 1 fair value of an equity security below its carrying value is objective evidence of impairment. Impairment is then recognized as the difference between the
carrying value of the equity investment and the greater of its Level 1 fair value and the underlying equity investments value in use.

The Company has performed a value-in-use computation for its equity method investment in KPN as of December 31, 2013. The value-in-use
computation was based in-part on KPNs actual financial results for 2013 and financial projections for the years 2014 to 2016. Beyond the three-year period of the KPN projections, free-cash flow was projected by the Company at 0.5% real growth
rate to perpetuity (2.5% nominal, including projected inflation). The Company applied a discount rate of 7.2% (nominal) (5.8% in 2012) to the projected free cash flows of KPN, which is the estimated weighted average cost of capital. Based on the
computation performed, a value in use of the Companys 27.70% (29.7% in 2012) ownership interest of Ps.139.3 billion (Ps 55.9 billion in 2012) was estimated as of December 31, 2013, thus no impairment charge was required in the
Companys 2013 consolidated financial statements.

iii) Telekom Austria AG (Telekom Austria)

On June 15, 2012, the Company agreed to acquire approximately 21% of the outstanding shares of Telekom Austria AG (Telekom
Austria) from Marathon Zwei Beteiligungs GmbH, a wholly-owned subsidiary of RPR Privatstiftung, a private trust established by Mr. Ronny Pecik. Under the agreement, the Company acquired 5% of the outstanding shares of Telekom Austria, and
the right to acquire additional shares. On September 25, 2012, the Company exercised this right and acquired approximately 16% of the outstanding shares of Telekom Austria, after receiving the required regulatory approvals. As of
September 30, 2012, the Company held 22.76% of the outstanding shares of Telekom Austria. The total aggregate costs of the Companys investment in Telekom Austria is approximately 954 million (Ps.15,977,000). Telekom Austria
provides telecommunications services in Austria, Belarus, Bulgaria, Croatia, Liechtenstein, Macedonia, Serbia and Slovenia.

América Móvils interest in Telekom Austria is accounted for using the equity method in the consolidated financial
statements. Summarized financial information of the associated company, based on its IFRS financial information (adjusted for the Companys basis in such investee) is set out below:

The Company owned 104,875,874 shares of Telekom Austria, with a carrying value of Ps.16,752,724 and
Ps.17,649,976 as of December 31, 2012 and 2013, respectively, which equates to a carrying value of Ps.159.4 per share and Ps.98.91 respectively. Telekom Austria shares are traded on the Vienna Stock Exchange; however, the Company purchased its

The Company has performed a value-in-use computation for its equity method investment in Telekom Austria as of December 31, 2013 and
2012. The value-in-use computation was based in-part on Telekom Austrias actual financial results for 2013 and financial projections for the years 2014 to 2016. Beyond the three-year period of the Telekom Austria projections, free-cash flow
was projected by the Company at 1.0% real growth rate to perpetuity. The Company applied a discount rate of 6.9% (nominal) to the projected free cash flows of Telekom Austria, which is the estimated weighted average cost of capital. Based on the
computation performed, a value in use of the Companys 22.33% ownership interest of Ps.20.0 billion was estimated as of December 31, 2013, respectively, thus no impairment charge was required in the Companys 2013 consolidated
financial statements. In addition see Note 23 for subsequent events after December 31, 2013.

11. Derivative Financial Instruments

To mitigate the risk of future increases in interest rates for the servicing of its debt, the Company has entered into interest-rate swap
contracts in over-the-counter transactions carried out with financial institutions from which the Company has obtained the related loans. No collateral is given as security in connection with these transactions. The weighted-average interest rate of
the total debt is 3.5%.

An analysis of the derivative financial instruments contracted by the Company at December 31, 2012 and 2013
is as follows:

DCP

Embratel makes contributions to the DCP through Embratel Social Security FundTelos. Contributions are computed based on the salaries of
the employees, who decide on the percentage of their contributions to the plan (between 3% and 12% of their salaries). Embratel contributes the same percentage as the employee, capped at 8% of the participants balance. All employees are
eligible to participate in this plan.

The unfunded liability represents Embratels obligation for those participants that migrated
from the DBP to the DCP. This liability is being paid over a term of 20 years as of January 1, 1999. Unpaid balances are adjusted monthly based on the yield of the asset portfolio at that date and is increased based on the General Price Index
of Brazil plus 6 percentage points per year. At December 31, 2013, the balance of the DCP liability was Ps.213,770 (Ps.272,882, at December 31, 2012).

As of December 31, 2013, 2012 and 2011, the cost of labor were Ps.2,233, Ps.(1,713) and Ps.2,827, respectively.

Pensions and seniority premiums

Telmex
has an employee pension and seniority premium plan that covers most of its employees. Pensions and seniority premiums are determined based on the salary of employees in their final year of service, the number of years worked at Telmex and their age
at retirement.

Telmex has established an irrevocable trust fund and makes annual contributions to that fund, which are considered
deductible for purposes of income tax and employee profit sharing. The most important information related to labor obligations is as follows:

Fair value hierarchy

The Companys valuation techniques used to determine and disclose the fair value of its financial instruments are based on the following
hierarchy:

Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2: Variables other than quoted prices in Level 1 that are observable for the asset or liability, either directly (prices) or indirectly
(derived from prices); and

Level 3: Variables used for the asset or liability that are not based on any observable market data
(non-observable variables).

Fair value of derivatives financial instruments are valued using valuation techniques with observable market
inputs. To determine its Level 2 fair value, the Company applies valuation techniques including forward pricing and swaps models, using present value calculations. The models incorporate various inputs including credit quality of counterparties,
foreign exchange spot and forward rates and interest rate curves. Fair value of Level 2 debt has been determined using a model based on present value calculations incorporating the credit quality of AMX.

For the years ended December 31, 2012 and 2013, no transfers were made between Level 1 and Level 2 fair value measurement hierarchies.

Except for the fixed-rate senior notes, interest rates on the Companys debt are subject to variances in international
and local rates. The Companys weighted-average cost of borrowed funds at December 31, 2012 and 2013 was approximately 5.0% and 4.8%, respectively.

Such rate does not include commissions or the reimbursements for Mexican tax withholdings, typically a tax rate of 4.9%, that the Company must
make to international lenders. In general, fees on financing transactions add ten basis points to financing costs.

An analysis of the
Companys short-term debt at December 31, 2012 and 2013 is as follows:

During 2013, América Móvil issued 3 new notes for US$750,000 due 2016 with a coupon
of Libor +100 basis points, another 750,000 due 2023 with a coupon of 3.2590%, and £300,000 due 2033 with a coupon of 4.9480%. Likewise, in March 2013 AMX reopened the program of peso-denominated notes to raise Ps.7,500,000. Since
November 2012, we have issued peso-denominated notes that can be distributed and traded on a seamless basis in Mexico and internationally. The notes are registered with both the U.S. Securities and Exchange Commission and the Mexican Banking and
Securities Commission (CNBV). We sold Ps.15,000,000 of notes under the program in November 2012. We intend to use the program to raise a total of Ps.100,000,000 over five years to increase the share of Mexican pesos in our overall
funding.

Additionally, on September 6, 2013, América Móvil issued three hybrid notes due 2073 in three tranches. One
is for 900,000 and carries a coupon of 5.125% and has a first call option on September 6, 2018, and two others for 550,000 and £550,000 pay a 6.375% coupon and have a first call option on September 6, 2023 and
September 6, 2020, respectively.

It is important to mention that these notes are unsecured and deeply subordinated obligations and
rank junior to all our existing and/or future unsubordinated and ordinary subordinated indebtedness and senior to all existing and future classes of shares that comprises our equity. The aforementioned notes are effectively subordinated to all
existing and/or future liabilities of our subsidiaries.

(ii) Lines of credit granted or guaranteed by export credit agencies

The Company has medium- and long-term financing programs for the purchase of equipment, with certain institutions, to promote exports and
provide financial support to purchase export equipment from their respective countries. The outstanding balance under these plans at December 31, 2012 and 2013 is approximately Ps.6,212,915 and Ps.4,575,477, respectively.

The Company has a line of credit with Banco Inbursa, S.A. (related party) as explained in Note 18d.

(iii) Domestic Senior Notes (Certificados Bursatiles)

At December 31, 2012 and 2013, debt under domestic notes aggregates to Ps.46,841,688 and Ps.37,461,105, respectively. Some bear interest at
fixed rates, and others at variable rates based on TIIE (a Mexican interbank rate).

(iv) Lines of Credit

At December 31, 2012 and 2013, debt under Lines of Credit aggregates to Ps.3,717,659 and Ps.5,094,799, respectively.

In May 2011, the Company entered into two revolving syndicated facilities  one for U.S.$2,000,000 and one for the Euro equivalent of
2,000,000. Loans under the facility bear interest at variable rates based on LIBOR and EURIBOR.

Early payment of debt

In 2012 and 2013, the Company made advance payments against its debt with third parties of approximately Ps.23,000,000 and Ps.19,000,000,
respectively.

Restrictions (TELMEX)

A portion of the debt is subject to certain restrictions with respect to maintaining certain financial ratios, as well as restrictions on
selling a significant portion of groups of assets, among others. At December 31, 2013, the Company was in compliance with all these requirements.

A portion of the debt is also subject to early maturity or repurchase at the option of the
holders in the event of a change in control of the Company, as so defined in each instrument. The definition of change in control varies from instrument to instrument; however, no change in control shall be considered to have occurred as long as
Carso Global Telecom or its current shareholders continue to hold the majority of the Companys voting shares.

In conformity with its credit agreements, the Company is obligated to comply with certain financial and operating commitments. Such covenants
limit, in certain cases, the ability of the Company or the guarantor to: pledge assets, carry out certain types of mergers, sell all or substantially all of its assets, and sell control of Telcel.

Such covenants do not restrict the ability of AMXs subsidiaries to pay dividends or other payment distributions to AMX. The more
restrictive financial covenants require the Company to maintain a consolidated ratio of debt to EBITDA (earnings before interest, tax, depreciation and amortization) that does not exceed 4 to 1, and a consolidated ratio of EBITDA to interest paid
that is not below 2.5 to 1 (in accordance with the clauses included in the credit agreements). Telmex Internacional is subject to financial covenants of maintaining a ratio of debt to EBITDA that does not exceed 3.5 to 1, and a consolidated ratio of
EBITDA to interest paid that is not below 3 to 1 (in accordance with the clauses included in the applicable credit agreements).

Several
of the financing instruments of the Company are subject to early extinguishment or re-purchase, at the option of the debt holder in the case that a change in control occurs.

As of December 31, 2012 and 2013, the Company complied with all the conditions established in our debt agreements.

At December 31, 2013, approximately 49% of América Móvils total outstanding consolidated debt is guaranteed by
Telcel.

17. Commitments and Contingencies

a) Leases

At December 31, 2012 and
2013, the Company has entered into several lease agreements with related parties and third parties for the buildings where its offices are located (as a lessee), as well as with the owners of premises where the Company has installed radio bases. The

Telcel

COFECOMonopolistic practices investigations

Radiomovil Dipsa, S.A. de C.V. (Telcel), is the target of two investigations into alleged monopolistic practices originally
commenced by the Federal Antitrust Commission (Comisión Federal de Competencia, or COFECO). One concerns alleged actions by Telcel and certain of its distributors in relation to the purchase and sale of cellular
phones from and to third parties. COFECO determined that Telcel engaged in anti-competitive behavior, and the agency imposed fines totaling Ps.3.3 million and ordered that Telcel cease the alleged monopolistic practices immediately. Telcel has
challenged COFECOs findings and fines in the courts. No final ruling has been issued. The Company has not established a provision in the accompanying financial statements for loss arising from these contingencies.

The second investigation concerns alleged monopolistic practices in the mobile termination (interconnection) market. In April 2011, COFECO
imposed a fine of Ps.11,989 million against Telcel for alleged monopolistic practices that according to COFECO also constituted a repeat offense. In May 2011, Telcel challenged the fine through an administrative appeal (recurso de
reconsideración), before COFECO and proposed a series of undertakings to COFECO related to the alleged monopolistic practices. In May 2012, COFECO revoked the fine. As a condition to the revocation of the fine, Telcel agreed to comply
with the undertakings that it proposed to COFECO. As a result of a constitutional amendment enacted in 2013, the Federal Telecommunications Institute (Instituto Federal de Telecomunicaciones or IFT), is responsible for
monitoring Telcels compliance with respect to such undertakings. Six mobile operators challenged the revocation of the fine through an appeal for relief (juicio de amparo), and four of such proceedings have now been resolved on terms
favorable to Telcel.

As part of the undertakings agreed upon with COFECO, Telcel issued terms of reference governing interconnection with
its network, including mobile termination rates for the period from 2011 to 2014. Such terms are available for all operators terminating calls in Telcels network. As a result of changes to the legal regime governing Mexican telecommunications
services, the mobile termination rates Telcel will charge during 2014 will be different than those agreed upon with COFECO.

##### Table of Contents

The IFT will oversee compliance by Telcel with the agreed undertakings and, upon any breach by
Telcel, the IFT may impose a fine of up to 8% of Telcels annual revenues. Telcel is in full compliance with the agreed undertakings.

Mobile
termination rates

Mobile termination rates for the years 2005 through 2010 between Telcel and affiliated operators Axtel and Avantel
were the subject of a number of legal proceedings. The Supreme Court of Justice (Suprema Corte de Justicia de la Nación) addressed these disputes in a series of rulings during 2012 and early 2013, which generally (i) determined
that the Mexican Ministry of Communications and Transportation (Secretaría de Comunicaciones y Transportes or SCT), does not have authority to resolve disputes over mobile termination rates,
(ii) confirmed that the Federal Telecommunications Commission (Comisión Federal de Telecomunicaciones, or COFETEL), has authority to determine mobile termination rates based on its own cost models,
(iii) for certain periods (2005-2007), confirmed the rates established by COFETEL, and (iv) for other periods (2008-2010), required COFETEL to reissue resolutions determining mobile termination rates between the parties. Such resolutions
are still pending.

Several mobile operators began proceedings with COFETEL (desacuerdos de interconexión), to establish
applicable mobile termination rates and other interconnection conditions for the years 2011 to 2013. COFETEL determined rates for 2011, but not for 2012 and 2013. As a result of changes to the Mexican telecommunications laws, the IFT is now
responsible for determining rates for 2012 and 2013. Such resolutions are still pending.

On March 26, 2014, the IFT issued a
resolution imposing on Telcel a specified interconnection rate it must charge to all operators for traffic to Telcels network for the period commencing on April 6 and ending on December 31, 2014. The rate was reduced from Ps.0.3490
to Ps.0.2045. Telcel has filed an appeal for relief (juicio de amparo), against the IFTs resolution.

Reduction in mobile
termination rates and any potential disparity between the mobile termination rates made available by Telcel to other operators and the rates to be established by the IFT for the years 2012 to 2013 may give rise to contractual claims among Telcel and
other operators for reimbursement or payment, as the case may be, of amounts paid or owed between Telcel and such operators. The Company expects that these mobile termination rates will continue to be the subject of litigation and administrative
proceedings. The Company cannot predict when or how these matters will be resolved. The competitive and financial effects of any resolution could be complex and difficult to predict.

The Company has established provisions in the accompanying financial statements for the losses AMX considers probable and estimable for
approximately Ps.2,500 million, but the Company cannot estimate the amount of possible loss.

Short Message Services (SMS)Rates

On March 26, 2014, the IFT issued a resolution imposing on Telcel a specified SMS termination rate it must charge to all mobile operators
for the period commencing on April 6 and ending on December 31, 2014. The rate was reduced from Ps.0.1537 to Ps.0.0391. Telcel has filed an appeal for relief (juicio de amparo), against the IFTs resolution.

Short Message Services (SMS)Royalties

The Mexican Tax Administration Service (Servicio de Administración Tributariaor SAT), notified Telcel of tax
assessments totaling Ps.320 million alleging nonpayment of royalties for revenues generated by short message services during 2004 and 2005. The SAT is alleging that Telcel owes such amounts because short message services constitute concessioned
services. AMX has challenged the assessments on the grounds that short message services are value-added services that are not concessioned services. In other proceedings,

##### Table of Contents

COFETEL and more recently its successor, the IFT, have ruled that short text messages are subject to the interconnection regulatory regime and that such services do not constitute value-added
services and are therefore concessioned services. AMX has established a provision in the accompanying financial statements for the loss arising from these contingencies that the Company considers probable.

Trademarks Tax Assessments

In
2006 and 2007, the SAT notified Telcel and the Company of assessments related to the deduction in 2003 of certain trademark payments, which the SAT asserted should have been taken over the course of several years and not in a single year. These
claims were settled in 2013.

In December 2007, the SAT notified Telcel of an assessment of Ps.453.6 million (Ps.243.6 million plus
adjustments, fines and late fees), in connection with a deduction of certain advertising expenses in 2004. SAT took the position that the payments of advertising expenses were not deductible because Telcel also paid royalties relating to the same
trademarks. In July 2011, SAT notified the Company of an assessment of Ps.773.0 million (Ps.292 million plus adjustments, fines and late fees), related to the same payments described in the December 2007 assessment above. Under the
consolidation regime applicable in Mexico at the time, Telcel was permitted to take up to 40% of the deduction, while the parent company was permitted to take the remaining 60%. This July 2011 assessment relates to the Companys portion of the
deduction. These claims were settled in 2013.

Class Actions

The Federal Consumer Bureau (Procuraduría Federal del Consumidor, or Profeco), filed an action similar to a
class action in Mexican courts on behalf of customers who filed complaints before it, alleging deficiencies in the quality of Telcels network in 2010 and breach of customer agreements. If the action is resolved in favor of Profeco,
Telcels customers would be entitled to compensation for damages.

Beginning in 2012, Mexican Law provides for class actions seeking
compensation. These class actions may arise from antitrust, consumer, data and privacy protection issues, as well as administrative, criminal and environmental violations, and may be filed by the competent authorities or the affected groups.

Five class actions have been initiated against Telcel (i) three are related to quality of service and were filed by consumers;
(ii) one also filed by consumers is related to quality of service, but in addition compares wireless voice, data and broadband international rates claiming that rates offered by Telcel are higher than international comparable rates; and
(iii) one was filed by Profeco and relates to a network technical malfunction that occurred in January 2013.

The Company currently
does not have enough information to determine whether these class actions could have an adverse effect on our business and results of operations if they are resolved against us. Consequently, Telcel has not established a provision in the
accompanying financial statements for loss arising from these contingencies.

Carso Global Telecom

In November 2010, the SAT notified Carso Global Telecom, S.A. de C.V. (CGT), of an assessment of Ps.3,392 million related to
the change in the scope of fiscal consolidation in 2005. SAT alleges that this change generated a reduction in the participation of CGT in its subsidiaries, resulting in increased income taxes. CGT has challenged this assessment in federal tax
courts, and this challenge is still pending. AMX has not established a provision in the accompanying financial statements for loss arising from this contingency.

Sercotel

In August 2011, SAT
notified Sercotel, S.A. de C.V. (Sercotel), of an assessment of Ps.6,308 million related to withholding taxes, interest payments and certain income that SAT contends should have been reported

##### Table of Contents

at Sercotel in 2005. Sercotel paid Ps.118 million related to withholding taxes and interest payments and challenged the portion of the assessment related to the income reporting in an
administrative appeal with the tax authority. In 2013, Sercotel obtained a partial favorable resolution, and the SAT reduced the amount of the assessment considerably. In May 2013, Sercotel invoked the benefits derived from a tax
amnesty program(programa de amnistía fiscal)offered by SAT and settled the claim.

In March 2012, SAT notified Sercotel
and the Company of a fine of approximately Ps.1,400 million because of the SATs objection to the allegedly improper tax implications of the transfer of certain accounts receivable from one of the Companys subsidiaries to Sercotel. AMX
challenged the fine by filing an administrative appeal with the tax authority which is still pending. The Company also expects SAT will issue tax assessments of Ps.2,750 million relating to the same matter.

In December 2012, SAT notified Sercotel of an assessment of Ps.4,824 million related to income that SAT contends should have been reported at
Sercotel in 2006. Sercotel challenged the assessment related to the taxability in an administrative appeal with the tax authority. In 2013, Sercotel obtained a partial favorable resolution, and the SAT reduced the amount of the assessment
considerably. In May 2013, Sercotel invoked the benefits derived from a tax amnesty program(programa de amnistía fiscal)offered by the SAT and settled the claim.

The Company has not established a provision in the accompanying financial statements for loss arising from these contingencies.

Telmex

COFECO/IFTMonopolistic practices
investigations

Teléfonos de México, S.A.B. de C.V. (Telmex) and Teléfonos del Noroeste,
S.A. de C.V. (Telnor), are the target of three investigations into alleged monopolistic practices originally commenced by COFECO. In the first two investigations, it was determined that Telmex and Telnor engaged in monopolistic
practices in the fixed-network interconnection services market. Telmex and Telnor have filed legal proceedings (including an appeal for relief (juicio de amparo), against these rulings and their cases are pending resolution. In the third
investigation, in February 2013 COFECO determined that Telmex and Telnor engaged in monopolistic practices in the wholesale market for dedicated-link leasing (local and domestic long-distance). Telmex and Telnor challenged that resolution and their
cases are still pending.

AMX cannot predict when or how these investigations will be resolved. The competitive and financial effects of
any final findings by the IFT could be complex and difficult to predict. They may include monetary fines or additional regulations or restrictions that may limit our flexibility and our ability to adopt competitive market policies, any of which
could materially reduce Telmex and Telnors revenues in future periods.

AMX has not established a provision in the accompanying
financial statements for loss arising from these contingencies.

Proceedings Concerning Telmexs Relationship with Dish México

As previously disclosed, in November 2008, Telmex entered into several agreements with Dish México, S. de R.L. de C.V.
(Dish México), and its affiliates, which operate a DTH Pay TV system in Mexico, pursuant to which Telmex is currently providing billing and collection services, among others. Subject to obtaining specific government
authorizations, Telmex could invest directly in a joint venture with Dish México.

AMX and Telmex have been subject to
investigations in the past related to these arrangements. Recently, they have received new inquiries from governmental authorities on this subject including inquiries from the IFT and the Mexican National Banking and Securities Commission
(Comisión Nacional Bancaria y de Valores orCNBV). Although the Company cannot predict the outcome of these inquiries, AMX is confident that our

##### Table of Contents

actions in connection with our relationship with this customer have been appropriate in all respects, because the arrangements were limited to providing services, providing financial support (in
the form of leasing equipment and committing to locate fallback financing) and agreeing to purchase and sale options that could result in Telmex investing in the customer if specified regulatory conditions were met, including the approval from the
relevant competent authorities. The Company does not believe these arrangements have at any time been material to our results, our financial condition or our compliance with our regulatory obligations.

However, the 2013 constitutional amendments prohibit a preponderant economic agent from obtaining direct or indirect benefit from the free of
charge mandatory must offer, must carry rules for cable television providers. In March 2014, the IFT determined that Telmex is part of an economic group that is a preponderant economic agent, and consequently Telmex may not benefit from
these rules. We will ensure that Telmex does not benefit from any application of the must offer, must carry rules.

AMX has
not established a provision in the accompanying financial statements for loss arising from these contingencies.

Brazil

Claro Brasil and Americel

Anatel Inflation-Related
Adjustments

The Brazilian National Telecommunications Agency (Agência Nacional de Telecomunicações or
Anatel), challenged the calculation of inflation-related adjustments due under the agreements it had with Tess, S.A. (Tess), and ATL-Telecom Leste, S.A. (ATL), two of our Brazilian
subsidiaries that were merged with and into Claro Brasil, S.A. (Claro Brasil), which assumed their rights and obligations.

Under the agreements with Anatel, 40% of the concession price was due upon execution and 60% was due in three equal annual installments
(subject to inflation-related adjustments and interest), beginning in 1999. The companies made all payments, but Anatel challenged the companies calculation of the inflation-related adjustments related to the payment corresponding to 60% of
the concession price, alleging that such calculation resulted in a shortfall, and requesting additional payment. The amount of this shortfall and the method used to calculate monetary correction are subject to judicial disputes.

The companies filed declaratory and consignment actions seeking resolution of the disputes. The court of first instance ruled against
ATLs declaratory suit in October 2001 and ATLs consignment action in September 2002. Subsequently, ATL filed appeals, which are still pending. Similarly, the court of first instance ruled against Tess consignment action in June
2003 and against Tess filing for declaratory action in February 2009. Tess also filed an appeal, which is still pending.

In
December 2008, Anatel charged Tess approximately Ps.1,501 million (approximately R$269 million). Tess obtained an injunction from the Federal Court of Appeals suspending payment until the pending appeal is resolved. Similarly, in March 2009, Anatel
charged ATL approximately Ps.1,066 million (approximately R$191 million). ATL also obtained an injunction from the Federal Court of Appeals suspending payment until the pending appeal is resolved. In April 2013, the appeal filed by ATL with
respect to the declaratory suit was denied, and Claro Brasil filed a new appeal.

The Company calculated the amount of the shortfall based
on a specific method and certain assumptions. If other methods or assumptions are used, the amount of damages may increase. In December 2013, Anatel calculated monetary correction in a total amount of Ps.8,317 million (approximately R$1,490
million).

The Company has established a provision of Ps.3,215 million (approximately R$576 million), in the accompanying financial
statements for loss arising from these contingencies, which AMX considers probable.

Consumer Protection Lawsuit (DPDC)

In July 2009, the Brazilian Federal and State Prosecutor Office, along with the Consumer Protection and Defense Agency and other Brazilian
consumer protection agencies, initiated a lawsuit against Claro Brasil alleging that it has violated certain regulations governing the provision of telecommunications services. The amount claimed by the plaintiffs is Ps.1,675 million
(approximately R$300 million). In September 2013, the relevant court ruled against Claro Brasil, and awarded the plaintiff Ps.167 million (approximately R$30 million). The plaintiffs and Claro Brasil challenged the ruling and those challenges are
still pending.

The Company has not established a provision in the accompanying financial statements to cover loss arising from this
contingency, which the Company does not consider probable.

Tax assessments against Americel and Claro Brasil (PIS/COFINS)

In December 2005, the Brazilian Federal Revenue Service issued tax assessments against Claro Brasil and Americel in respect of PIS (Programa
de Integração Social) and COFINS (Contribuição para o Financiamento da Seguridade Social) taxes (which are levied on gross revenue), for 2000 through 2005. In addition, in March 2006, the Brazilian Federal
Revenue Service issued tax assessments against ATL related to certain tax deductions taken by ATL in connection with its PIS and COFINS obligations. As discussed above, Claro Brasil is the corporate successor to ATL.

In January 2011, the Brazilian Federal Revenue Service issued tax assessments against Claro Brasil regarding allegedly improper offsetting of
certain tax deductions claimed by Claro Brasil in connection with its PIS and COFINS obligations. The total amount of these tax assessments, which Americel and Claro Brasil are contesting in pending challenges, was Ps.7,898 million (approximately
R$1,415 million), including fines and interest as of December 31, 2013. The Company has established a provision of Ps.48 million (approximately R$8.6 million), in the accompanying financial statements for the loss arising from these
contingencies that AMX considers probable.

Separately, Claro Brasil and Americel have commenced lawsuits against the Brazilian Federal
Revenue Service seeking a ruling on constitutional grounds that they may exclude state value added tax (ICMS) payments and interconnection fees from the base used to calculate PIS and COFINS tax obligations. Pending a final ruling and pursuant to
applicable Brazilian procedure, the Company paid tax based on its position in the lawsuit, and established a provision for the disputed amounts. The total amount in dispute was approximately Ps.9,054 million (approximately R$1,622 million).

ICMS Tax Credits

The Brazilian
Federal Revenue Service has issued multiple tax assessments against Claro Brasil and Americel alleging that they improperly claimed certain tax credits under the state value added tax (Imposto sobre Operações relativas à
Circulação de Mercadorias e sobre Prestações de Serviços de Transporte Interestadual e Intermunicipal e de Comunicação or ICMS) regime in each Brazilian state. The Company is
contesting all of these tax assessments in multiple separate proceedings, first at the administrative level and then in the judicial courts, and these proceedings are at various stages. AMX has received rulings in some of these cases, including some
that are unfavorable, which the Company has appealed. The total amount of the tax assessments is approximately Ps.15,417 million (approximately R$2,762 million), including fines and interest as of December 31, 2013. The Company has established
a provision of Ps.977 million (approximately R$175 million), in the accompanying financial statements for the loss arising from these contingencies that the Company considers probable.

countries against some of its Brazilian tax obligations. During 2011, Claro Brasil terminated its challenge with respect to Ps.1,379 million (approximately R$247 million), in tax assessments and
paid those amounts to the Brazilian Federal Revenue Service, to preserve the right to offset the foreign tax withheld related to such tax assessments against its Brazilian tax obligations in future years. The total amount of the tax assessments that
Claro Brasil is contesting as of December 31, 2013 is approximately Ps.614 million (approximately R$110 million). The Company has not made a provision in the accompanying financial statements to cover loss arising from this contingency.

Americel have filed an injunction challenging a federal law that created the Brazilian Communication Company (Empresa Brasileira de Comunicação or EBC) that is to be partially funded by mobile operators. If
Claro Brasil and Americel are unsuccessful in their challenge, the total amount they would be required to contribute to EBC through December 31, 2013 is approximately Ps.2,406 million (approximately R$431 million). AMX has made a judicial
deposit in this amount. The Company has established a provision of Ps.2,406 million (approximately R$431 million), in the accompanying financial statements for loss arising from this contingency, which AMX considers probable.

FUST and FUNTTEL Funding

Anatel
has issued tax assessments against Claro Brasil and Americel totaling Ps.5,805 million (approximately R$1,040 million), relating to alleged underpayment of their funding obligations for the Telecommunications System Universalization Fund (Fundo
de Universalização dos Serviços de Telecomunicações or FUST) and the Telecom Technologic Development Fund (Fundo para o Desenvolvimento Tecnológico das
Telecomunicações or FUNTTEL) from 2006 to 2010. The assessments claim that interconnection and activation fee revenues should not have been excluded from the basis used to calculate funding obligations. Claro
Brasil and Americel have challenged the tax assessments, and the challenges are still pending. The Company has not made a provision in the accompanying financial statements to cover loss arising from this contingency.

TFIInstallation Inspection Fee

Anatel charged Claro Brasil and Americel the amount of Ps.8,032 million (approximately R$1,439 million) as of December 31, 2013, related
to the installation inspection fee (Taxa de Fiscalização de Instalação or TFI) allegedly due for the renewal of radio base stations and handsets. Claro Brasil and Americel have challenged the
amount charged, arguing that there was no new equipment installation that could lead to this charge, and the challenges are still pending. AMX has not established a provision in the accompanying financial statements and does not consider any loss to
be probable.

Other tax contingencies

Claro Brasil and Americel have other on-going tax litigations in the total amount of Ps.1,189 million (approximately R$213 million) as of

Net

ICMS

In 2011 and 2013, Net
Serviços de Comunicação S.A. (Net) was assessed by the Secretary of the Treasury of the State of Sao Paulo for the loss of the tax benefit of reducing the ICMS base it is entitled to, alleging that Net did not
include revenues from the rental of equipment in the ICMS base. The amount of this assessment as of December 31, 2013 was Ps.2,026 (approximately R$363 million). The tax authority claims that from (i) January 2008 to November 2009; and
(ii) January 2010 to December 2011, Net should have paid the ICMS on pay TV



F-81

##### Table of Contents

services revenues at a rate of 25% instead of the rate of 10% actually applied by Net. In the tax authoritys view, Net lost the rate reduction benefit allowed by ICMS Agreement No.57/99
because Net did not include locação de equipamento (rental of equipment) in its revenues. Net based its calculation on the interpretation of the Brazilian Superior Court that the rental of equipment should not
be confused with a subscription TV service, and therefore cannot be taxed by ICMS and, consequently, Net should not lose the tax benefit, as alleged by the tax authority. However, there is no specific precedent (at either the administrative or
judicial levels) on the issue, and it is not possible to predict the outcome of this matter. The Company has established a provision in the accompanying financial statements.

In 2008 and 2010, Net Brasília Ltda. (Net Brasília), a Net subsidiary, received tax assessment notices from
the State Internal Revenue of the Distrito Federal in the amounts of Ps.1,149 million (approximately R$155.4 million and R$50.5 million), respectively, as of December, 2013, relating to the ICMS tax. The tax authority claims that during the period
from January 2003 to June 2009 Net Brasília should have paid the ICMS on Pay TV services revenues at a rate of 25% instead of the rate of 10% actually applied by Net Brasília. In the tax authoritys view, the rate reduction
benefit allowed by ICMS Agreement No. 57/99 expired on December 31, 2001. The Company has not established a provision in the accompanying financial statements to cover loss arising from these contingencies.

Net Rio Ltda. (Net Rio), a Net subsidiary, received a tax assessment notice from the State Tax Authority of the State of
Rio de Janeiro in the updated amount of Ps.1,367 million (approximately R$245 million) relating to the ICMS tax. The tax authority alleged that as a result of delays in the payment of its ICMS tax during the period from November and December 2001.
Thus, Net Rio lost its rate reduction benefit until September 2002. Net Rio has recorded liabilities related to the period from November and December 2001 in the amount of Ps.210 million (approximately R$37.6 million). Based on analysis performed by
legal counsel after an unfavorable decision from the lower court Net Rio made an additional provision to the period from January to September 2002 in the amount of Ps.1,150 million (approximately R$206 million), as of December, 2013.

CSLL/IRPJ

In 2009, Net São
Paulo Ltda., a Net subsidiary, received a tax assessment issued by the Brazilian Internal Revenue Service questioning part of the expenses considered as deductible in its calculation of IRPJ and CSLL from 2004 to 2008, amounting to Ps.3,053 million
(approximately R$547 million). In October 2010, a first instance decision reduced this amount to Ps.2,071 million (approximately R$371 million). As of December 31, 2013, the total amount dispute is Ps.2,657 million (approximately R$476
million). Net has determined that a loss is possible but not probable and accordingly AMX has not established a provision in the accompanying financial statements.

In 2012 and 2013, Net received a tax assessment in the amount of Ps.770 million (approximately R$138 million) issued by the Brazilian Internal
Revenue Service. The tax assessment questioned part of the expenses considered as deductible in our calculation of income tax and social contribution bases for the period between 2007 and 2008 related to its subsidiaries Net Belo Horizonte Ltda, Net
Rio and Net Brasília. Net has determined that a loss is possible but not probable and accordingly AMX has not established a provision in the accompanying financial statements.

Imposto sobre Operações Financeiras (IOF)

Net and its controlled companies have centralized cash management and cash transfers made under a current intercompany account. Management
determined that such transfers are not subject to financial transaction tax IOF charges. However, the Federal Revenue Service may deem such transfers to be inter-company loans. In the event such transfers are deemed to be inter-company loans, AMX
may be subject to IOF, on the amount of the loans. IOF applies to loans between non-financial entities at a maximum rate of 1.5% per year where the principal amount and the term for repayment is fixed, and at a daily rate of 0.0041% on the
outstanding balance,

without limit on the total amount of tax payable, if the principal amount of the loan is not fixed. In view of certain adverse court decisions as to the applicability of this law, the Company has
established a provision of Ps.569 million (approximately R$102 million) as of December 31, 2013.

Other civil and labor contingencies

Ecuador

Conecel

Tax Assessments

During 2008, the
Ecuadorian Revenue Services (SRI), notified Conecel of tax assessments in the amount of Ps.1,804 million (approximately US$138 million) (not including interest and penalties), relating to special consumption (ICE), value-added,
income and withholding taxes for the years 2003 to 2006. In March 2008, Conecel paid SRI Ps.183 million (approximately US$14 million), for these tax assessments (including fines) and filed challenges with the SRI with respect to Ps.1,661 million
(approximately US$127 million). In December 2008, SRI notified Conecel of a resolution that denied the challenges and in January 2009, Conecel filed a lawsuit before a Tax Court in Guayaquil challenging the tax assessments and providing a bank
guarantee of Ps.170 million (approximately US$13 million), which represented 10% of the contested amount. The Tax Court issued its final resolution in March 2012. The Tax Courts resolution was favorable with respect to Ps.314 million (US$24
million), of the disputed amount. The Company has appealed the unfavorable portion of the resolution before the National Court of Justice (Corte Nacional de Justicia), and in July 2013, Conecel made a partial withdrawal of its appeal and as a
result made a payment to SRI for an amount of Ps.1,216 million (approximately US$93 million considering the payment of the accrued interest). A resolution for the remaining portion of the tax assessment (approximately Ps.709 million (US$54.2
million)) is still subject to the Courts decision.

In addition, in 2011 and 2012, SRI notified Conecel of tax assessments in the
amount of Ps.1,556 million (approximately US$119 million), relating to income taxes for the 2007, 2008 and 2009 fiscal years. Conecel filed lawsuits before a Tax Court in Guayaquil challenging the tax assessments and such lawsuits are still pending.

The Company has established a provision of Ps.392 million (approximately US$30 million) in the accompanying financial statements for the
loss arising from these contingencies that AMX considers probable.

Fine imposed by the SCPM

In February 2014, following a regulatory claim filed in 2012 by the state-owned operator, Superintendency of Control of Market Power
(Superintendencia de Control del Poder del Mercadoor SCPM), imposed a fine on Conecel of Ps.1,809 million (US$138.4 million), for alleged monopolistic practices related to five locations which the state-owned operator
argues that Conecel has exclusive rights to deploy its network preventing others

from doing so. In March 2014, Conecel challenged the fine and posted a guarantee for 50% of its value. Through a judicial order issued during the same month, the competent court admitted

g) On April 22, 2013, the Companys shareholders approved, among other resolutions, the
(i) payment of a cash dividend of $0.22 pesos per share to each of the shares of its capital stock series AA, A and L, payable in two equal installments of $0.11 pesos; and (ii) increase in the amount of
funds available for the acquisition of the Companys own shares by Ps.40 billion pursuant to Article 56 of the Mexican Securities Market Law.

Retained earnings and other reserves distributed as dividends and the effects derived from capital reductions, are subject to income tax at
the rate at the date of distribution, except for the restated stockholder contributions or distributions made from the net taxed profit account (Cuenta de Utilidad Fiscal Neta Consolidada or CUFIN).

The dividends paid in excess of the account are subject to income tax on a grossed-current base rate. Since 2003, this tax may be credited
against income tax for the year in which the dividends are paid and the following two years against the income tax and estimated payments. The payment of dividends described above comes from the balance of the Companys CUFIN.

Legal reserve

According to the Mexican
General Mercantile Corporation Law, companies must appropriate from the net profit of each year at least 5% to increase the legal reserve until it reaches 20% of capital stock at par value. This reserve may not be distributed to stockholders during
the existence of the Company. At December 31, 2012 and 2013, the legal reserve amounted to Ps.358,440.

Restrictions on Certain Transactions

The Companys bylaws provide that any transfer of more than 10% of the combined A Shares and AA Shares, effected in one or more
transactions by any person or group of persons acting in concert, requires prior approval by our Board of Directors. If the Board of Directors denies such approval, however, Mexican law and the Company bylaws require it to designate an alternate
transferee, who must pay market price for the shares as quoted on the Mexican Stock Exchange.

Payment of Dividends

Dividends, either in cash or in kind, paid with respect to the L Shares, A Shares, L Share ADSs or A Share ADSs will generally be subject to a
10% Mexican withholding tax (provided that no Mexican withholding tax will apply to distributions of net taxable profits generated before 2014). Nonresident holders could be subject to a lower tax rate, to the extent that they are eligible for
benefits under an income tax treaty to which Mexico is a party.

20. Income Tax and Asset Tax

I) Mexico

América Móvil, S.A.B. de
C.V. was the controlling company in the tax consolidation in accordance with prevailing corporate and tax law through December 31, 2013, and as authorized by the tax authorities in 2002.

##### Table of Contents

From 2002 to 2013, the Company determined its income tax for each year on a consolidated basis,
which in simple terms consisted of including the taxable income or tax loss of each subsidiary in AMXs tax results as the controlling company, in proportion to a given percentage of América Móvils equity interest in each
subsidiary.

As a result of the 2014 Tax Reform, on December 11, 2013 a new Law on Income Tax was issued, and the Law of the Business
Flat Tax was eliminated.

Tax Consolidation

In 2010, Mexicos tax consolidation regime was significantly amended to establish a maximum deferral period for current year income tax of
five years while requiring previously applied tax consolidation benefits to be reversed (commonly referred to as recaptured) and remitted to the tax authorities in installments over the sixth to tenth years subsequent to the year in
which the benefits were taken.

Therefore, in 2010, the Company calculated the income tax it had deferred through 2004, while in 2011,
2012 and 2013, it calculated its income tax corresponding to 2005, 2006 and 2007, respectively. Similarly, these taxes must be remitted in 5 annual installments.

Tax consolidation benefits resulted from:



| | i) | Tax losses applied in the tax consolidation that would not have otherwise been carried forward individually by the entity that generated them; and
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------



| | ii) | Other items (apart from tax losses) that give rise to tax consolidation benefits, including losses on sales of shares not deducted individually by the entity that generated them; special consolidation items related to
transactions carried out between consolidating entities; and dividends declared by consolidated subsidiaries as of 1999 that were not paid from the balance of their CUFIN or the Net reinvested taxed profits account (CUFINRE).
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The individual CUFIN and CUFINRE balances of the groups entities can result in taxable profits in conformity with the Mexican Income Tax
Law (MITL). These amounts are referred to as CUFIN differences.

The deconsolidation effects with respect to tax losses that
were carried forward under the consolidation regime amounted to Ps.3,279,356, which is being paid by AMX in the amounts and terms set forth in the law.

Optional Regime

The new Income Tax Law
establishes the optional regime for corporate groups to defer the remittance of the deferred income tax of the groups subsidiaries, under the terms and conditions established in Articles 59 to 71 of the MITL. In addition to the above, the
Company meets the requirements for adopting this regime under Article 60 of the MITL, and accordingly, the Company filed its notice of incorporation into the optional regime under the terms and conditions published by the tax authority on
February 17, 2014. Also, in conformity with rule 1.3.22.8 of the Miscellaneous Tax Rules, the Company has declared its intention to the option contained in such rule, which allows companies with unused tax losses at December 31, 2013 to
carry forward these losses under the new regime.

Corporate tax rate

The income tax rate applicable in Mexico for 2010, 2011 and 2012 was 30%.

On December 7, 2009, a tax reform was approved that increased the corporate income tax rate from 28% to 30% for the years from 2010 to
2012 and was scheduled to be decreased to 29% in 2013 and 28% in 2014 and thereafter. However, the Mexican Federal Internal Revenue Act enacted in December 2012 established that the corporate income tax rate will remain at 30% in 2013 and that the
income tax rate reduction to 29% will take effect in 2014 and to 28% in 2015 and thereafter. The effect of the change in the corporate income tax rate on

deferred taxes as of December 31, 2012 resulted in an amount charged to deferred tax expense of Ps.155,599 in 2012. Furthermore, for fiscal year 2013, the Mexican Federal Internal Revenue
Act, enacted in December 2013, established that the corporate income tax rate is 30%. The effect on the change in the tax rate was Ps.138,849.

The deferred tax assets are in tax jurisdictions in which the Company considers that, based on financial
projections of its cash flows, results of operations and synergies between subsidiaries, the Company will generate taxable income in subsequent periods.

The Company does not recognize a deferred tax liability related to the undistributed earnings of its subsidiaries, because it currently does
not expect these earnings to be taxable or to be repatriated in the near future. The Companys policy has been to distribute the profits when it has paid the corresponding taxes in its home jurisdiction and the tax can be accredited in Mexico.

At December 31, 2012 and 2013, the balance of the contributed capital account (CUCA) is Ps.387,806,147 and
Ps.417,052,837, respectively, and the CUFIN balance is Ps.379,500,778 and Ps.415,327,853, respectively.

II) Foreign Subsidiaries

a) Results of operations

The foreign
subsidiaries determine their taxes on profits based on their individual taxable income, in accordance with the specific tax regimes of each country. The combined income before taxes and the combined provision for taxes of such subsidiaries in 2011,
2012 and 2013 are as follows:

b) The tax loss carryforwards in the different countries in which the Company operates have the
following terms and characteristics:

i) The Company has accumulated approximately B$7,057 million in net operating loss carry-forwards
(NOLs) in its various Brazilian subsidiaries, equating to approximately Ps.38,879,043 as of December 31, 2013. Through December 31, 2013, the Companys Brazilian operations are concentrated in its subsidiaries Claro,
Embratel and Net, each having varying levels of NOLs. In Brazil there is no expiration of the NOLs. However, the NOL amount in each year may not exceed 30% of the taxable income for such year. Consequently, in the year in which taxable
income is generated, the effective tax rate is 25% rather than the 34% corporate tax rate.

In Brazil, deferred tax assets are recognized
for tax losses to the extent that the realization of the related tax benefit through future taxable profits is probable, as well as for other temporary items. The benefit in income taxes expense for the years ended December 31, 2011, 2012 and
2013, attributable to the change in estimate over the recoverability of the tax loss carryforwards, was Ps.0, Ps.1,200,520 and Ps.2,321,679, respectively, and is shown as a credit in deferred income tax.

Through December 31, 2013, the aforementioned Brazilian subsidiaries did not file tax returns on a consolidated basis, although the
Company has initiated strategies to merge the entities in the near term so as to recover the NOLs currently recorded. The Company believes that it is more likely than not that it will recognize the benefit of unreserved NOLs in future
periods, primarily through continuing merged operations, tax planning strategies and other sources of taxable income.

ii) In Chile, tax
loss carryforwards have no expiration date and the corporate tax rate in that country is 17%. Consequently, at the time tax losses are realized, taxpayers obtain a benefit of only 17% of the amount of the loss generated.

iii) In Mexico the tax loss carryforwards expire in ten years on a stand-alone basis.

21. Segments

América Móvil
operates in different countries. As mentioned in Note 1, the Company has operations in Mexico, Guatemala, Nicaragua, Ecuador, El Salvador, Costa Rica, Brazil, Argentina, Colombia, United States, Honduras, Chile, Peru, Paraguay, Uruguay, Dominican
Republic, Puerto Rico and Panama. The accounting policies for the segments are the same as those described in Note 2.

The CEO, who is the
Chief Operating Decision Maker (CODM), analyzes the financial and operating information by geographical segment, except for Mexico, which shows América Móvil (Corporate and Telcel) and Telmex as two segments. All
significant operating segments that represent (i) more than 10% of consolidated revenues, (ii) more than the absolute amount of the reported 10% of profits or loss and (iii) more than 10% of consolidated assets, are presented
separately.

23. Subsequent Events

a) On January 16, 2014, the Company, through its subsidiary Tracfone Wireless Inc., acquired the assets of Start Wireless Group, Inc. (known
commercially as Page Plus), a mobile virtual network operator located in the U.S. Page Plus provides services to approximately 1.4 million subscribers and offers prepaid plans for voice, SMS and data services. The amount paid for these
assets was approximately US$120,000.

b) On March 7, 2014 the Company received a resolution issued by the Federal Telecommunications
Institute (Instituto Federal de Telecomunicaciones, or IFT) which determined that an economic interest group comprised of AMX and its operating subsidiaries, including Radiomóvil Dipsa, S.A de C.V. (Telcel) and
Teléfonos de México, S.A.B. de C.V. (Telmex), as well as Grupo Carso, S.A.B. de C.V. and Grupo Financiero Inbursa, S.A.B. de C.V., constitutes the preponderant economic agent in the telecommunications market, and which
imposed certain asymmetrical regulations, among which are the following:



| | (i) | Interconnection: Regulation of interconnection, including the imposition of (a) asymmetric rates to be determined by the IFT; and (b) an interconnection framework agreement (convenio marco de interconexión);
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | Sharing of Infrastructure: Regulation of other operators access to and use of the Companys passive infrastructure, including towers, sites, ducts and rights of way, at rates to be negotiated amongst the
operators and, where agreement cannot be reached, to be determined by the IFT using a long-run average incremental costs methodology;
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | Local Loop Unbundling: Regulation of local loop unbundling, including the imposition of rates to be determined by the IFT using a long-run average incremental cost methodology;
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | Leasing of Dedicated Links: Regulation of dedicated-link leasing for interconnection services and local, domestic and international long distance services, at rates to be negotiated amongst the operators and, where
agreement cannot be reached, to be determined by the IFT using a retail minus methodology, except for dedicated-link leasing for interconnection services, where a long-run average incremental costs methodology will be used for determining the
applicable rates;
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) | Roaming: Regulation of the provision of wholesale roaming services, at rates to be negotiated amongst the operators and, where agreement cannot be reached, to be determined by the IFT using a long-run average
incremental costs methodology;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (vi) | Elimination of National Roaming Charges: The elimination of national roaming charges to the Companys subscribers;
| | ---- | ------------------------------------------------------------------------------------------------------------------



| | (vii) | Mobile Virtual Operators: Regulation of mobile virtual network operators access to services provided by the Company to its subscribers, at rates to be negotiated amongst the operators and, where agreement cannot
be reached, to be determined by the IFT using a retail minus methodology;
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (viii) | Certain Obligations on the Provision of Retail Services: Certain rates for the provision of telecommunications services to the Companys subscribers shall be subject to rate control and/or authorization by the IFT,
using a series of methodologies related to maximum prices and replicability tests that are currently under analysis. The measures also impose a series of obligations relating to the sale of services and products, including the obligation to offer
individually all services that are offered under a bundle scheme; limited exclusivity on handsets and tablets; and the obligation to unlock handsets;
| | ------ | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ix) | Content: Regulation of content, including the prohibition on acquiring transmission rights for any territory within Mexico on an exclusive basis with respect to relevant content (contenidos audiovisuales relevantes), as
determined from time to time by the IFT, including without limitation national soccer play-offs (liguilla), FIFA world cup soccer finals and any other event where large audiences are expected at a national or regional level; and
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (x) | Information and Quality of Service Obligations: Several obligations related to information and quality of service, including the publication of a series of reference terms (ofertas públicas de referencia) for
wholesale and interconnection services that are subject to the asymmetric regulations imposed by the IFT, and rules regarding accounting separation.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | The resolution issued by the IFT is currently being analyzed by AMX and its subsidiaries from an economic, technical, regulatory, operating and business perspective in order to be able to evaluate its effects.
| |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

c) On March 18, 2014, the Company reported that its Board of Directors decided to submit a proposal to the shareholders
during the ordinary shareholders meeting expected to be held on April 28, 2014 to (i) pay a cash dividend of Ps.0.24 from the consolidated CUFIN account, payable in two installments, to the holders of the Companys series AA,
A and L shares that were outstanding at the dividend payment date (including the preferential dividend corresponding to L series shares), subject to subsequent share repurchase or reissue adjustments, among other
corporate events that could vary the number of outstanding shares at the payment date of the dividend; and (ii) allocate Ps.30,000,000 for share repurchases in conformity with Article 56 of the Mexican Securities Trading Act.

d) On March 28, 2014 the IFT issued a resolution, whereby AMXs rates will be determined asymmetrically for interconnection, termination
and transit services, with respect to mobile and fixed services provided by Telcel and Telmex, as applicable, beginning April 6, 2014 through December 31, 2014.

This resolution was issued by the IFT following a prior resolution in which the Institute determined that an economic interest group comprised
of AMX and its operating subsidiaries, including Telmex and Telcel, as well as Grupo Carso, S.A.B. de C.V. and Grupo Financiero Inbursa, S.A.B. de C.V., constitutes the dominant operator in the telecommunications sector, and in which the IFT imposed
specific asymmetric measures.

The asymmetrical rates that apply to Telmexs services during the period from April 6, 2014 to
December 31, 2014 are as follows:



| |  |  | Interconnection within the same regional node: Ps.0.02015 per minute
| | - |  | --------------------------------------------------------------------



| |  |  | Interconnection between regional nodes that depend on a national node: Ps.0.02258 per minute
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | Interconnection between regional nodes that depend on different national nodes: Ps.0.02340 per minute
| | - |  | -----------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | Traffic within the same regional node: Ps.0.00864 per minute
| | - |  | ------------------------------------------------------------



| |  |  | Transit between regional nodes that depend on a national node: Ps.0.01108 per minute
| | - |  | ------------------------------------------------------------------------------------



| |  |  | Transit between regional nodes which depend on different national nodes: Ps.0.01190 per minute
| | - |  | ----------------------------------------------------------------------------------------------

The asymmetrical rates that apply to Telcels termination services (for voice and SMS) during the period from April 6, 2014 to December
31, 2014 are as follows:



| |  |  | Termination for mobile users under calling party pays arrangements: Ps.0.2045
| | - |  | -------------------------------------------------------------------------------



| |  |  | Termination rate for short messages (SMS) sent by mobile users: Ps.0.0391
| | - |  | -------------------------------------------------------------------------

This resolution was
issued by the IFT in its capacity as an independent Constitutional body after a bill was submitted to Congress to establish the new Federal Law on Telecommunications and Broadcasting, and the resolution represents a substantial reduction in
interconnection, termination and transit rates compared to other operators in Mexico. Management believes fees referred to in the resolution are comparatively lower than those prevailing for the same services in most countries in the world.

e) In April 2014, the Company filed a challenge (juicio de amparo) to the decision issued by the IFT, through which it determined that an
economic interest group comprised of AMX and its operating subsidiaries, including Telmex and Telcel, as well as Grupo Carso, S.A.B. de C.V. and Grupo Financiero Inbursa, S.A.B. de C.V., constitutes the dominant operator in the telecommunications
sector, and through which the IFT imposed specific asymmetric measures. AMX operating subsidiaries Telmex and Telcel also filed challenges to the resolution.

f) In March 2014, the Company purchased shares representing 3.1% of the outstanding shares of Telekom Austria from Inmobiliaria Carso and
Control Empresarial de Capitales, S.A. de C.V, which may be deemed for certain purposes to be under common control with the Company. As a result, as of March 31, 2014 the Company directly or indirectly owns 26.8% of Telekom Austrias
outstanding shares.

g) On April 23, 2014, the Company entered into a shareholders agreement (the Shareholders
Agreement) with Telekom Austrias largest shareholder, Österreichische Industrieholding AG (ÖIAG). The Shareholders Agreement is subject to certain regulatory approvals. As a result of signing the Shareholders
Agreement, the Company is required by Austrian law to purchase all the outstanding shares of Telekom Austria not held by the Company, ÖIAG or Telekom Austria (the TA Offer). Under the terms of the Shareholders Agreement, the Company and
ÖIAG have agreed to vote in favor of, and contribute to, a capital increase for Telekom Austria of 1 billion. The capital increase is subject to the closing of the TA Offer.

24. Supplemental Guarantor Information
