#### Risks Relating to Brazil
***The Brazilian government has exercised, and continues to exercise, significant influence over the Brazilian economy. This influence, as well as Brazilian political and economic conditions, could adversely affect us and the trading price of our common shares and ADSs.***

The Brazilian federal government frequently exercises significant influence over the Brazilian economy and occasionally makes significant changes in policy and regulations. The Brazilian government's actions to control inflation and other policies and regulations have often involved, among other measures, changes in interest rates, changes in tax policies, wage and price controls, foreign exchange controls, currency devaluations, capital controls and limits on imports. Our financial condition, as well as our business and results of operations and the market price of our common shares and ADSs, may be adversely affected by changes in government policies, especially those related to our sector, such as changes in telephone fees and competitive conditions, as well as general economic factors, including:

● exchange rates and currency fluctuations;

● exchange controls and restrictions on remittances abroad, (including with regards to the payment of dividends) such as those imposed in 1989 and early 1990;

● growth or downturn of the Brazilian economy;

● inflation;

● energy policy;

● interest rates and monetary policies;

● liquidity of domestic capital and lending markets;

● fiscal policies and changes in tax laws;

● economic, political or social instability;

● the policies adopted or to be adopted by the new administration in Brazil following the 2022 presidential elections;

● labor and social security policies, laws and regulations; and

● other political, diplomatic, social and economic developments in or affecting Brazil.

Uncertainty over whether the Brazilian federal government will implement changes to the policies, regulations or standards affecting these or other factors in the future may affect economic performance, which may have an adverse effect on us and the trading price of our common shares and ADSs. Past economic and political instability has led to a negative perception of the Brazilian economy and higher volatility in the Brazilian securities markets, which has adversely affected us and the trading price of our common shares and ADSs.

These issues may be exacerbated by the results of the Brazilian presidential election held in October 2022, in which the former President Luiz Inácio Lula da Silva (from 2003 to 2010) was reelected. There is uncertainty as to which policies will be adopted by the new government. We cannot assure you that the new government will maintain policies designed to promote macroeconomic stability, fiscal discipline and domestic and foreign investments, and failure on the part of the new government to do so may adversely impact

[**Table of Contents**](#TOC)

Brazil's economy, the prices of securities issued by Brazilian issuers such as us and ultimately our business, financial condition and results of operations.

#### Political instability may materially adversely affect the Brazilian economy, our business, and the market price of our common shares and ADSs.
Brazil's political environment has historically influenced and continues to influence the performance of Brazil's economy, as well as investor and general public confidence, resulting in economic slowdowns and an increase in the volatility of securities issued by Brazilian companies.

The President of Brazil has the power to determine policies and issue government measures relating to the Brazilian economy and, as a result, affect the operations and financial performance of companies, including us. We cannot predict what policies the President of Brazil will establish or whether such policies or changes in existing policies will have an adverse effect on the Brazilian economy or our business, results of operations, financial condition and the market price of our common shares and ADSs.

In addition, any difficulties the Brazilian government may face establishing a majority in Congress could result in a government impasse, political unrest and mass demonstrations and/or strikes that could materially adversely affect our operations. Uncertainties about the implementation of changes in monetary, tax and social security laws and policies, may contribute to economic instability. These uncertainties and any new measures may increase volatility in the Brazilian securities market.

Finally, Brazil has experienced significant political turmoil in recent years, including the impeachment of Dilma Rousseff, the former president (who was removed from office in August 2016), investigations of her successor, Michel Temer (who left office in January 2019), as part of the ongoing "Lava Jato" investigations, investigations of the current president, Jair Bolsonaro, by the STF for alleged unlawful conduct, several requests for impeachment filed against the former president in relation to his management of the response to the COVID-19 pandemic, and a highly polarized election in 2022.

#### Inflation and government efforts to curb inflation may contribute to economic uncertainty in Brazil, adversely affecting our business and results of operations.
In the past, Brazil has recorded high inflation rates, which, combined with other measures taken by the Brazilian government to fight inflation and speculation on what measures would be taken, has materially adversely affected the Brazilian economy. The measures taken by the Brazilian government to control inflation have included maintaining strict monetary policies and high interest rates, which restricted the availability of credit and reduced economic growth. The COPOM often adjusts interest rates in Brazil during periods of economic uncertainty in order to achieve the inflation targets established by the Brazilian government. Inflation, the Brazilian government's efforts to curb inflation and speculation regarding any future measures, has had material adverse effects on the Brazilian economy and contributed to economic uncertainty in Brazil, which increases volatility in the Brazilian capital markets and may materially adversely affect our business and results of operations.

Periods of higher inflation coupled with higher interest rates and other measures to combat inflation may lead to reduced demand for our products. Inflation is also likely to increase some of our costs and expenses, which we may not be able to fully pass on to customers and could adversely affect our operating margins and operating income. In addition, inflation affects our financial liquidity and financial capital resources primarily by exposing us to variations in our floating-rate loans. Rising interest rates may also impact the costs of our fundraising and indebtedness, increasing our financial expenses. Such an increase could adversely affect our ability to pay our obligations to the extent it reduces cash on hand.

According to the IPCA index, Brazilian inflation rates were 10.1%, 4.5%, 4.3% and 3.7% in 2021, 2020, 2019, and 2018, respectively. In 2022, the inflation rate, as measured by the IPCA, decreased to 5.8%, reflecting tax cuts on fuel, electric energy, and telecom prices, some dissipation of global supply chain pressures and monetary policy tightening.

As a result of still inflationary pressures and macroeconomic instability, the Brazilian government has historically adopted monetary policies that resulted in high interest rates in Brazil. The Central Bank determines the basic interest rates generally available to the Brazilian banking system, based on the expansion or contraction of the Brazilian economy, inflation rates and other economic indicators. Throughout 2022, the COPOM increased the Selic rate from 9.25% to 13.75%, indicating that the basic interest rate will be maintained at this level for a sufficiently long period to ensure the inflation convergence to the targets. Brazil may continue to

[**Table of Contents**](#TOC)

experience high levels of inflation in the future and inflationary pressures may lead to the Brazilian government's intervening in the economy and introducing policies that could harm our business and the price of our common shares and ADSs.

Currently, fixed broadband and mobile service providers, including us, use the IGP-DI to adjust their prices and television and cable service providers use the IGP-M. The IGP-DI and IGP-M are inflation indexes developed by the FGV, a private organization. Since 2006, telephone fees for fixed-line services have been indexed to the IST, as adjusted by a productivity factor, or X Factor, which is defined by ANATEL Resolution No. 507/2008.

The IST is an index composed of other domestic price indexes (including the IPCA, IGP-DI and IGP-M, among others) that is intended to reflect the telecommunications industry's operating costs. As a result, this index serves to reduce potential discrepancies between our industry's revenue and costs, and thus reduce the apparent adverse effects of inflation on our operations. The productivity factor, pursuant to which ANATEL is authorized to adjust fee rates, is calculated based on a compensation index established by ANATEL to incentivize operational efficiency and to share related gains in earnings from fixed-line services with customers through fee rate adjustments. The IST is calculated based on a 12-month period average. This may cause increases in our revenues above or below our costs (including salaries), with potentially adverse impacts on our profitability.

**Inflation and government measures to combat inflation, along with speculation about governmental measures, have had significant negative effects on the Brazilian economy in the recent past, including heightened volatility in the Brazilian securities market. These policies may be incapable of preventing increases in the inflation rate. In the event of an increase in inflation, we may not be able to adjust the prices we charge our customers to offset the effects of inflation on our cost structure, which may adversely affect us.**

***Fluctuations in exchange rates may adversely affect our ability to meet liabilities denominated or linked to foreign currencies or reduce our income in foreign currency, and may have a material adverse effect on the market value of our common shares and ADSs.***

The Brazilian currency has been historically volatile and has been devalued frequently over the past three decades. Throughout this period, the Brazilian government has implemented various economic plans and used various exchange rate policies, including sudden devaluations, periodic mini-devaluations (during which the frequency of adjustments has ranged from daily to monthly), exchange controls, dual exchange rate markets and a floating exchange rate system. Although long-term depreciation of the real is generally linked to the rate of inflation in Brazil, depreciation of the real occurring over shorter periods has resulted in significant variations in the exchange rate between the *real*, the U.S. dollar and other currencies. The exchange rate between the U.S. dollar and the Brazilian *real* has experienced significant fluctuations in recent years. In 2017, the *real* depreciated 1.5% against the U.S. dollar, followed by another depreciation of 17.1% in 2018, 4.0% in 2019, 22.4% in 2020 and 7.4% in 2021. The *real*/U.S. dollar exchange rate reported by the Central Bank was R$5.286 per US$1.00 as of December 31, 2022, which reflected a 5.1% appreciation in the real against the U.S. dollar during 2022, reflecting the positive trade balance result and better-than-expected activity performance. As of January 09, 2023, the *real*/U.S. dollar exchange rate reported by the Central Bank was R$5.258 per US$1.00. There can be no assurance that the *real* will not again depreciate against the U.S. dollar or other currencies in the future.

As of December 31, 2022, 5.6% of our total indebtedness of R$19.3 billion was denominated in foreign currency. Approximately 9.5% of our operating costs and expenses are payable or linked to payment by us in U.S. dollars or Euros. By contrast, 99.9% of our revenue is generated in reais, except income derived from hedging transactions, international long-distance interconnection fees and services to customers outside of Brazil.

To the extent that the value of the *real* decreases relative to the U.S. dollar or the Euro, our commitments payable or linked to payment by us in foreign currencies become more expensive. Although our accounts receivable denominated in foreign currencies would also appreciate, the net effect could adversely affect our revenue and expenses. In addition, the IST inflation index does not adequately reflect the true effect of exchange rate fluctuations. Thus, our revenue, when translated to U.S. dollars, does not adequately reflect the true effect of exchange rate fluctuations, which may affect our results of operations.

We use derivative instruments to limit our exposure to exchange rate risk. Since September 1999, we have hedged all of our foreign currency-denominated bank debt using swaps and other derivative instruments. Since May 2010, the company began using net balance coverage, which is the hedging of net positions in foreign exchange exposures, or assets (issued invoices) minus liabilities (received invoices) for foreign exchange exposures, substantially reducing our risk to fluctuations in exchange rates. We could still continue to face exchange rate exposure with respect to our planned capital expenditures however, as a small part of our planned

[**Table of Contents**](#TOC)

capital expenditures are denominated or indexed in foreign currencies (mostly U.S. dollars). We systematically monitor the amounts and time of exposure to exchange rate fluctuations and may hedge positions when deemed appropriate.

***Political, economic and social developments and the perception of risk in other developed and emerging countries may adversely affect the Brazilian economy, our business, and the market price of Brazilian securities, including our common shares and ADSs.***

The market for securities issued by Brazilian companies may be influenced, to varying degrees, by economic conditions in both developing and developed economies. The reaction of investors to developments in other countries may have an adverse impact on the market value of securities of Brazilian companies. The prices of shares traded on the B3, for example, have historically been sensitive to fluctuations in interest rates in the United States, as well as variations of the main U.S. stock exchanges. Additionally, crises in other emerging countries or the economic policies of other countries may reduce investor demand for securities of Brazilian companies, including our common shares and ADSs. Any of the foregoing developments may adversely affect the market value of our common shares and ADSs and hinder our ability to access the capital markets and finance our operations in the future on acceptable terms and costs, or at all.

To the extent that economic problems in emerging market countries or elsewhere adversely affect Brazil, our business and the market value of our common shares and ADSs could be adversely affected. Furthermore, we cannot assure you that, in the event of adverse developments in emerging market economies, the international capital markets will remain open to Brazilian companies or that the resulting interest rates in such markets will be advantageous to us. Decreased foreign investment in Brazil may negatively affect growth and liquidity in the Brazilian economy, which in turn may have a negative impact on our business. Disruption or volatility in the global financial markets could further increase negative effects on the financial and economic environment in Brazil, which could have a material adverse effect on us.

#### Any further downgrading of Brazil's credit rating could reduce the trading price of our common shares and ADSs.
We may be harmed by investors' perceptions of risks related to Brazil's sovereign debt credit rating. Rating agencies regularly evaluate Brazil and its sovereign ratings, which are based on a number of factors including macroeconomic trends, fiscal and budgetary conditions, indebtedness metrics and the perspective of changes in any of these factors.

Brazil was downgraded to non-investment grade status by S&P in September 2015, by Fitch Ratings in December 2015, by Moody's in February 2016 . Brazil was further downgraded by S&P in February 2016 and January 2018 and by Fitch in May 2016 and February 2018. Brazil's sovereign rating is currently rated by the three major risk rating agencies as follows: BB- by S&P and Fitch Ratings and Ba2 by Moody's.

Brazil's sovereign credit rating is currently rated below investment grade by the three main credit rating agencies. Consequently, the prices of securities issued by Brazilian companies have been negatively affected. A reversal of the current recovery of the Brazilian economic activity, instability in the political environment, changes in fiscal austerity guidelines, among other factors, could lead to a revision of the agencies' outlooks, which could be followed by further ratings downgrades. Any further downgrade of Brazil's sovereign credit ratings could heighten investors' perception of risk and, as a result, cause the market price of our common shares and ADSs to decline.

#### Risks Relating to the Brazilian Telecommunications Industry and Us
***Information technology is key to our business and we could be subject to cybersecurity risks.***

The risks derived from cybersecurity are among our most relevant risks. Despite advances in the modernization of the network and the replacement of legacy systems, we operate in an environment increasingly prone to cyber-threats. Therefore, it is necessary to continue to identify and remedy any technical vulnerabilities and weaknesses in our operating processes, as well as to strengthen our capabilities to detect and react to incidents. This includes the need to strengthen security controls in the supply chain (for example, by focusing on the security measures adopted by our partners and other third parties), as well as to ensure the security of the services in the cloud.

Telecommunications companies worldwide face continuously increasing cybersecurity threats as businesses have become increasingly more digital and dependent on telecommunications and computer networks and cloud computing technologies.

[**Table of Contents**](#TOC)

Cybersecurity threats may include gaining unauthorized access to our systems or propagating computer viruses or malicious software to misappropriate sensitive information like customer data, corrupt our data or disrupt our operations. Unauthorized access may also be gained through traditional means such as the theft of laptop computers, data devices and mobile phones. Further, our employees or other persons may have unauthorized or authorized access to our systems and leak data and/or take actions that affect our networks or otherwise adversely affect us or our ability to adequately process internal information.

We manage these risks through a number of technical and organizational measures, which are part of our digital security strategy, including, access control measures, backup systems, log review of critical systems, vulnerabilities checks, network segregation measures and protective systems such as firewalls, intrusion prevention systems, virus scanners and other physical and logical security measures. However, the application of these measures cannot guarantee the mitigation of all risks.

For more information, see "Item 4. Information on the Company—B. Business Overview—Technology—Network Security."

***We are dependent on key personnel and the ability to hire and retain additional personnel.***

We believe that our success will depend on the continued services of our senior management team and other key personnel. Our management team is comprised of highly qualified professionals, with extensive experience in the telecommunications industry. The loss of the services of any of our senior management team or other key employees could adversely affect our business, financial condition and results of operations. We also depend on the ability of our senior management and key personnel to work effectively as a team.

Our future success also depends on our ability to identify, attract, hire, train, retain and motivate highly skilled technical, managerial, sales and marketing personnel. Competition for such personnel is intense, and we cannot guarantee that we will successfully attract, assimilate or retain a sufficient number of qualified personnel. Failure to retain and attract the necessary technical, managerial, sales and marketing and administrative personnel could adversely affect our business, financial condition and results of operations.

***We are subject to liabilities relating to third party contractors, which may have a material adverse effect on our business and results of operations.***

We are exposed to contingent liabilities resulting from our contracting structure, which includes third-party service providers. Such potential liabilities may involve labor claims by third-party providers that are treated as direct employees as well as joint liability claims relating to wage or overtime pay complaints and workplace injury claims. If a significant portion of these contingent liabilities is decided against us and for which we have not made adequate provisions, our financial condition and results of operation may be adversely affected.

Furthermore, if the contracting of third party service are considered to involve the main activities of the company, it may be characterized as direct employment, which would significantly increase our costs and as a result, we may be subject to administrative proceedings by the relevant labor regulators and may be required to pay fines to the third-party service providers.

***Consolidation in the telecommunications market may increase competition in the near future and may change Brazilian market dynamics.***

Mergers and acquisitions may change market dynamics, create competitive pressures, force small competitors to find partners and impact our financial condition; and may require us to adjust our operations, marketing strategies (including promotions), and product portfolio.

The entry of a new market participant with significant financial resources or potential changes in strategy by existing telecommunications service providers can change the competitive environment in the Brazilian market. We may be unable to keep pace with these changes, which could affect our ability to compete effectively and have a material adverse effect on our business, financial condition and results of operations.

Additional joint ventures, mergers and acquisitions among telecommunications service providers are possible in the future. If such consolidation occurs, it may result in increased competition within our market. We may be unable to adequately respond to pricing pressures resulting from consolidation in our market, adversely affecting our business, financial condition and results of

[**Table of Contents**](#TOC)

operations. We may also consider engaging in merger or acquisition activity in response to changes in the competitive environment, which could divert resources away from other aspects of our business.

***We face significant competition in the Brazilian market.***

The relative competitive stability in the Brazilian telecommunications sector observed in 2021 was maintained in 2022. Telecommunications operators continued to focus on improving their base of accesses by attracting customers to higher-value products. On the mobile side of the business, market participants mostly sought to sell hybrid plans (*planos controle*) and pure postpaid plans to consumers to increase overall ARPUs and profitability. On the fixed-line side of the business, we have seen competition both from large and small players to capture customers for fiber connectivity or upgrades for higher internet speeds, mostly driven by increased demand caused by the COVID-19 pandemic and the increased supply of high-quality broadband given the expansion in the rollout of fiber optic networks. In addition, customers are demanding higher quality services and greater mobile data availability, which require higher investments in the development, modernization, expansion and continuous improvement of the quality of our services and the experience of our customers.

As a result, we have continued faced significant competition, mainly driven by the following factors: (1) commercial and pricing pressures from new portfolios launched by competitors; (2) increased 4G, 4.5G and fiber optic network coverage and improved service quality by our competitors; and (3) low-cost alternative services, such as voice and text services provided over IPs, and IPTV/VoD services, which may affect our competitive position in the market. We continuously monitor market conditions to anticipate future competitive challenges and opportunities and analyze how to address them. Nevertheless, our operational results, market position, competitiveness in the market and margins may be adversely affected if we are unable to keep the same pace as our competitors.

#### Our business, operations and results have been, and may continue to be, adversely impacted by the effects of the COVID-19 pandemic.
Since December 2019, SARS-CoV-2, a novel strain of coronavirus referred to as COVID-19, has spread throughout the world. On January 31, 2020, the WHO announced that COVID-19 was a global health emergency and on March 3, 2020, the World Health Organization categorized COVID-19 as a pandemic. The COVID-19 pandemic has resulted in numerous deaths and the imposition of local, municipal and national governmental "shelter-in-place" and other public health measures, border closures and other travel restrictions, causing unprecedented economic disruption in much of the world. In Brazil, states and municipalities, including those in which we operate, adopted directives set by the Brazilian Ministry of Health (Ministério da Saúde), and implemented measures to control the propagation of the disease, such as travel restrictions and measures to encourage social distancing, which resulted in the shutdown of restaurants, hotels, shopping centers, places of public congregation, parks and other public spaces. Uncertainty about the effectiveness of vaccines and the emergence of new strains or mutations of the virus that render vaccination ineffective or inefficient can make it difficult or impossible for the government to contain the pandemic, which could contribute to the implementation of new restrictions, thereby negatively affecting our business and operations.

Since the beginning of the COVID-19 pandemic, the Brazilian government determined that the telecom sector is an essential service, which allowed us to continue our field maintenance activities without violating restrictions on movement that were generally imposed to address the pandemic. However, in accordance with recommendations from authorities, we transitioned a substantial majority of our employees to hybrid or work-from-home.

In Brazil generally and in particular regions where we have a significant employee presence, facilities or critical operations, the outbreak of COVID-19 impacted our ability to manage day-to-day operations and service our customers and resulted in, among other things, loss of revenue, although we have also experienced a decrease in our costs of operations due to lower variable costs such as sales commissioning, call centers, billing and advertising. Moreover, we implemented corporate and personal travel restrictions for employees and vendors, canceled events and enabled work-from-home for many employees by equipping them to safely support customers remotely. We also implemented additional safety measures for our retail stores and field operations teams. Additionally, at certain points of the pandemic, we were required to temporarily close or reduce operations at some of our retail locations, facilities and customer call centers, although these locations have been since reopened, oftentimes with reduced hours of operation or customer capacity limitations, as stay-at-home orders began to ease in São Paulo and other Brazilian cities. Although stay-at-home orders have eased in the primary markets in which we operate, we may be required to temporarily close or reduce operations at more of or all of our retail locations, facilities or call centers again if there is a resurgence of COVID-19 or its variants in the markets in which we operate. The foregoing effects, and other effects of COVID-19, may continue for an unknown period of time.

[**Table of Contents**](#TOC)

Our business has been, and may continue to be, negatively impacted by the effects of, or precautions taken to avoid exposure to, COVID-19, such as reduced travel or recommendations or mandates from governmental authorities to avoid large gatherings or to self-quarantine, and by the resulting disruptions to economic conditions and financial markets. Such impacts include, but are not limited to:

● Reduced sales of certain of our products and services, such as handset sales and upsells made through our retail stores and upsells through our call centers and other channels, as a result of public health measures;

● Reduced availability of certain equipment in the supply chain due to increased demand;

● Disruptions to our third-party providers, including those who provide many of our information technology, call center functions, certain accounting functions and other critical vendor services;

● Reduced workforces caused by, among other things, the temporary inability of the workforce to work due to illness, quarantine, or government mandates, or temporary unwillingness to work due to health concerns;

● Reduced customer demand or customer payment of accounts receivables as a result of adverse economic conditions resulting from the COVID-19 pandemic; and

● Increases in provisions for bad debt as a result of increased unemployment and the inability of certain customers to pay bills and late fees as a result of disruptions caused by the COVID-19 pandemic.

Potential future impacts include, but are not limited to:

● Service disruptions or reduced bandwidth for copper-based broadband customers due to significant short-term increases in bandwidth usage due to individuals working from home and/or significantly higher expenses attributable to infrastructure investments required to meet such higher network utilization trends;

● Imposition of governmental requirements preventing our termination services as a result of non-payment, thus encouraging customer defaults on invoices, resulting in a decline in our cash flows from operations and an increase in our expected losses on trade receivables;

● Increased supply chain risks such as increased scrutiny or embargoing of goods produced in infected areas;

● Increased health insurance and labor-related costs arising from illness, quarantine and the implementation of social distancing and work-from-home measures;

● Reduced employee productivity and a negative impact on the execution of our business plans and operations as employees must balance working remotely from home with personal responsibilities, such as child care and education;

● Increased risk of phishing and other cybersecurity attacks, and increased risk of unauthorized dissemination of sensitive personal information or proprietary or confidential information about us, our customers or other third parties as a result of employees or third-party vendors' employees working remotely; and

● In the event of continued restrictions on certain activities, or a natural disaster, power outage, connectivity issue or other event that impacts our employees' ability to work remotely, it may be difficult or, in certain cases, impossible, for us to continue to support our customers' needs and respond to inquiries through call center operations or to perform necessary or routine repairs, maintenance and installation activities, which could adversely affect our operations and sales.

The foregoing impacts, and other impacts of COVID-19 discussed elsewhere in these risk factors, are broadly consistent with those generally affecting the economic, financial, regulatory and political conditions in Brazil and elsewhere in the world, and are generally applicable to the industries and markets in which the Company and its subsidiaries operate. These impacts could materially increase our costs, negatively impact our consumer and business sales and damage the Company's financial condition, results of operations, cash flows and liquidity position, possibly to a significant degree.

Federal, state and municipal governments in Brazil may announce further restrictions on the general population and we cannot predict what effect this will have on our operations and sales in the long term. We cannot predict the duration of the pandemic, the

[**Table of Contents**](#TOC)

effectiveness of governmental or other measures taken to attempt to curb the pandemic, or the duration of any such measures. In addition, following the pandemic and the termination of any such governmental restrictions, the needs and preferences of our customers may have been altered. The continuation or a future resurgence of the pandemic could precipitate or aggravate the other risk factors that we face, which in turn could further materially and adversely affect our business, financial condition, liquidity, results of operations and profitability, including in ways that are not currently known to us or that we do not currently consider to present significant risks. We will continue to actively monitor the situation and may take further actions that alter our business operations as may be required by federal, state or local authorities, or that we determine are in the best interests of our employees, clients, suppliers and shareholders.

For more information about specific measures that we have adopted and potential impacts on our business operations, see "Item 4. Information on the Company—A. History and Development of the Company—Recent Developments—COVID-19 Pandemic" and "Item 5. Operating and Financial Review and Prospects— A. Operating Results—Overview—Effects of the COVID-19 Pandemic."

***Extensive government regulation of the telecommunications industry and our concession agreements may limit, in some cases, our flexibility in responding to market conditions, competition and changes in our cost structure or impact our fees.***

Our business is subject to extensive regulation, including any regulatory changes that may occur during the terms of our concession agreements and our authorizations to provide telecommunication services in Brazil. ANATEL, the main telecommunications industry regulator in the country, regulates, among other things:

● industry policies and regulations;

● licensing (including licensing of spectrum and bidding processes);

● fees and tariffs;

● competition incentives and restrictions (including our ability to grow by acquiring other telecommunications businesses);

● service, technical and quality standards;

● consumer rights;

● penalties and other sanctions;

● interconnection and settlement arrangements; and

● universal service obligations.

The Brazilian telecommunications regulatory framework is continuously evolving. The interpretation and enforcement of regulations, the assessment of compliance with regulations and the flexibility of regulatory authorities are all marked by uncertainty. We operate under authorizations and a concession from the Brazilian government, and our ability to maintain these authorizations and concessions is a precondition to our success. However, because of the changing nature of our regulatory framework, we cannot provide assurances that ANATEL will not adversely modify the terms of our authorizations and/or licenses. According to our operating authorizations and licenses, we must meet specific requirements and maintain minimum quality, coverage and service standards. Our failure to comply with such requirements may result in the imposition of fines, penalties and/or other regulatory responses, including the termination of our operating authorizations and concession. Any partial or total termination of any of our operating authorizations and licenses or our concession would have a material adverse effect on our business, financial condition, revenues, results of operations and prospects.

In recent years, ANATEL has been reviewing and introducing regulatory changes, especially regarding asymmetric competition measures and interconnection fees charged among local providers of telecommunications services. Asymmetric competition measures can include regulations intended to rebalance markets in which a market participant has distinct market power over other competitors. The adoption of disproportionately asymmetric measures could have a material adverse effect on our business, financial condition, revenues, results of operations and prospects.

With respect to interconnection fees, these are an important part of our revenue and cost bases. Such fees are charged by telecommunications service providers to each other in order to allow interconnected use of each other's networks. To the extent that

[**Table of Contents**](#TOC)

changes to the rules governing interconnection fees reduce the amount of fees we can receive, or our ability to collect such fees, our businesses, financial conditions, revenues, results of operations and prospects could be materially adversely affected.

Therefore, our business, results of operations, revenues and financial conditions could be negatively affected by the actions of the Brazilian authorities, including, in particular, the following:

● the introduction of new or stricter operational and/or service requirements;

● the granting of operating licenses in our areas;

● limitations on interconnection fees we may charge to other telecommunications service providers;

● imposition of significant fines or penalties regarding failures to comply with regulatory obligations;

● delays in the granting of, or the failure to grant, approvals for rate increases; and

● antitrust limitations imposed by ANATEL and CADE.

#### Our concession may be revised by the Brazilian government under certain circumstances.
We operate our fixed-line business in the state of São Paulo under a concession granted by the Brazilian government. According to the terms of this concession, we are obligated to meet certain universal service requirements and to maintain minimum quality and service standards. For example, ANATEL requires that we satisfy certain conditions with respect to, among other things, the expansion of our network to: (i) provide public pay-phone services under specific conditions, despite significant reductions in requirements by Decree No. 9,619/2018; (ii) provide private individual telephone service for locations with a population of over 300 persons, upon request by any consumer; and (iii) meet certain service quality targets (as reviewed by Resolution No. 717/2019, which remains under implementation). Our ability to satisfy these terms and conditions may be affected by factors beyond our control, and our failure to comply with the requirements of this concession may result in the imposition of fines of up to R$50 million per incident and/or other government sanctions, including the imposition of a preemptive ban on marketing our services or the termination of our concession. The partial or total termination of our concession or other authorizations would have a material adverse effect on our financial condition and results of operations.

Furthermore, our concession agreements provide that all assets owned by us, and which are indispensable to the provision of the services described in such agreements, are considered "reversible assets" (*bens reversíveis*) and are deemed to be part of the concession assets, subject to reimbursement or amortization as compensation for these assets. In 2021, with the publication of ANATEL Resolution No. 744, or the Public STFC Services Continuity Regulation (*Regulamento de Continuidade da Prestação do Serviço Telefônico Fixo Comutado Destinado ao Uso do Público em Geral* (*STFC*) em Regime Público), or the Continuity Regulation, ANATEL established that, upon the end of an STFC concession contract, reversible assets used for several services, including our public regime STFC services, would be subject to a right-of-use assignment, under fair and reasonable economic conditions, by us and the new service provider or the Brazilian government. In turn, the possession of reversible assets that are effectively and exclusively used to ensure the continuity of public regime STFC services would be reverted to the granting governmental authority if the service continues to be provided (either by the Brazilian government or by the new concessionaire service provider). In this way, the Concessionaire's assets, at the end of the concession contract on December 31, 2025, will not be susceptible to the reversal of its ownership to the Union. The assignment of the use of shared assets and the possession of exclusive assets of the STFC is now defined by means of specific contracts already provided for in the operational manual of the RCON, approved by Decision No. 269/2021/COUN/SCO. Pursuant to the administrative proceeding TC nº. 003.342/2022-0, in progress at the Federal Court of Accounts, a technical report stated that the RCON should be reviewed and such understanding shall still be submitted to the court's ruling. Moreover, according to ANATEL's interpretations of current regulations, reversible assets will not be available to creditors in the event of insolvency, bankruptcy or similar events, although there are differing interpretations, even among government agencies, and ongoing discussions regarding the treatment of reversible assets as a result of the passage of Law No. 13,879/2019, or the New General Telecommunications Law, on October 4, 2019. See "—A review of our concession agreements and/or the new telecommunications regulatory framework in Brazil could have a materially adverse effect on our operations."

[**Table of Contents**](#TOC)

#### A review of our concession agreements and/or the new telecommunications regulatory framework in Brazil could have a materially adverse effect on our operations.
The expiration date of our fixed-line concession agreements in São Paulo is December 31, 2025. These agreements contain a provision permitting ANATEL to review the concession agreements every five years and include revisions to terms and conditions that relate to network expansion, modernization and quality of service targets in response to changes in technology, competition in the marketplace and domestic and international economic conditions.

On June 24, 2014, ANATEL opened a public review and comment period for the revision of the terms of fixed-line concession agreements with respect to the 2016-2020 period. However, when the agency released the new version of the agreements in June 2017, operators disagreed with the inclusion by ANATEL of certain provisions and decided against executing new agreements with the agency. As a result, the agreements with respect to the 2011-2015 period remain in force. In January 2021, although new concession contracts had not yet been signed, the Brazilian government published Decree No. 10,610/2021, or PGMU V, which approves the revision of PGMU targets. PGMU V establishes that the remaining balance of the previous PGMUs must be used in the construction of backbone networks with optic fiber technology.These targets have been criticized by several of the local operators.

In addition, on October 4, 2019, the New General Telecommunications Law was enacted. This law revises the telecommunications regulatory framework by amending the General Telecommunication Law and significantly impacts this industry. The law permits fixed-line concession operators to migrate from a concession regime (in which the underlying assets must be reverted to the government at the end of the concession) to an authorization regime. ANATEL will be responsible for estimating the gains obtained by operators as a result of migrating from one regime to the other. According to the New General Telecommunications Law, on July 5, 2022, ANATEL presented a methodology with an estimate of the economic value associated with the adaptation of the concession instrument for authorization, to be validated by the Federal Court of Accounts, which after the vote of the rapporteur minister for the legality of the methodology presented by ANATEL, is under analysis by another minister, and should resume to the court's agenda in March. After the final decision by the Federal Court of Accounts about the methodology applied, ANATEL will indicate the final amount to the adaptation of the concession instrument for authorization. This final amount, after confirmation and acceptance by Telefónica, will be converted into investment projects not yet defined by ANATEL. For more information about the New General Telecommunications Law, see "Item 4. Information on the Company—B. Business Overview—Regulation of the Brazilian Telecommunications Industry—Other regulatory matters—Updated regulatory framework."

Any additional changes to laws, rules or regulations could have a material adverse effect on our operations and financial condition. Changes to our concession agreements or further changes to the current regulatory framework may entail the imposition of new requirements, including obligations to make specific investments and/or capital expenditures. ANATEL may also impose new service targets on us with values that we are not able to predict.

#### Our current radiofrequency licenses may not be renewed for additional periods.
Generally, current spectrum authorizations are valid for 15 years. Although the New General Telecommunications Law admits successive spectrum renewals, we cannot guarantee that our existing licenses will be renewed. According to the New General Telecommunications Law and Decree No. 10,402/2020, ANATEL may set specific conditions for such renewals, such as mandatory "refarming" processes in certain spectrum bands, or refuse renewal requests altogether. A refarming process can reduce the amount of spectrum available to each operator, depending on the configuration of the new blocks.

**Our current 850 MHz authorizations will expire between 2023 and 2028. If legal and regulatory requirements are met, ANATEL has agreed to the current authorizations for the use of radio frequencies in bands A and B, on a primary basis, until November 29, 2028. However, the specific conditions for renewal, including those related to economic valuation criteria and related obligations, were challenged by the affected service providers, including us. After ANATEL rejected complaints presented by the providers, a final disposition of the matter is still pending and will require a decision by the Brazilian Federal Court of Accounts (*Tribunal de Contas da União*), or the TCU.**

Furthermore, since our licenses for the 900 MHz and 1,800 MHz band will expire in 2023, their renewal has been requested and a final decision by ANATEL is still pending. For instance, in August 2022, ANATEL approved the renewal of 900 MHz and 1,800 MHz licenses held by TIM until 2032.

[**Table of Contents**](#TOC)

**Nevertheless, if there is no such renewal for the licenses previously mentioned, we would have to compete for new licenses in a spectrum auction. In addition, the coverage of our mobile services would be significantly affected by a loss of or failure to renew spectrum licenses. Further, in certain regions, our services may become unavailable, particularly in the event of a failure to renew or obtain all licenses for such regions. In the event of any of the foregoing circumstances, our business, financial condition, revenues, results of operations and prospects could be materially adversely affected.**

#### We are exposed to risks in relation to compliance with anti-corruption laws and regulations and economic sanctions programs.
We are required to comply with anti-corruption laws and regulations in Brazil and in jurisdictions where our securities are traded. In particular, we are subject, in Brazil, to Law No. 12,846/2013, and in the United States, to the U.S. Foreign Corrupt Practices Act of 1977. Additionally, our operations may be subject to, or otherwise affected by, economic sanctions programs and other forms of trade restrictions (hereinafter referred to as sanctions), including those administered by the United States, including the U.S. Treasury Department's Office of Foreign Assets Control.

**Although we have internal policies and procedures designed to ensure compliance with such anti-corruption laws and sanctions regulations (to the extent applicable), there can be no assurance that such policies and procedures will be sufficient or that our employees, directors, officers, partners, agents and service providers will not take individual actions in violation of our policies and procedures (or, otherwise in violation of the relevant anti-corruption and sanctions laws and regulations) for which we, our subsidiaries or such employees, directors, officers, partners, agents and service providers may be ultimately responsible. Violations of such laws and regulations could lead to sanctions, reputational harm, or other legal consequences that could have a material adverse effect on our business, results of operations and financial condition.**

#### We depend on key suppliers to obtain the necessary equipment and services for our business.
We depend on certain key suppliers of equipment and services, especially telecommunications network equipment and handsets, for the execution and development of our business. These suppliers may delay delivery, alter prices and limit supply as a result of problems related to their own businesses, over which we have no control. If these suppliers are not able to deliver equipment and services regularly, we may face problems with the continuity of our business activities, which may have an adverse effect on our business and results of operations.

***Certain key inputs are subject to risks related to importation, and we acquire other key inputs from a limited number of domestic suppliers, which may further limit our ability to acquire such inputs in a timely and cost-effective manner.***

The high growth in data markets in general and broadband in particular may result in a limited supply of equipment essential for the provision of such services, such as data transmission equipment and modems. The restrictions on the number of manufacturers imposed by the Brazilian government for certain inputs, mainly data transmission equipment and modems, and the geographical locations of non-Brazilian manufacturers of these inputs, pose certain risks, including:

● vulnerability to currency fluctuations in cases where inputs are imported and paid for with U.S. dollars, Euros or other non-Brazilian currency;

● difficulties in managing inventory due to an inability to accurately forecast the domestic availability of certain inputs; and

● the imposition of customs or other duties on key inputs that are imported.

If any of these risks materialize, they may result in our inability to provide services to our customers in a timely manner or may affect the prices of our services, which may have an adverse effect on our business, financial condition and results of operations.

***We make investments based on demand forecasts that may become inaccurate due to economic volatility and may result in revenues that are lower than expected.***

We make certain investments, such as the procurement of materials and the development of physical sites, based on our forecasts of the amount of demand that customers will have for our services at a later date (generally several months later). However, any major changes in the Brazilian economic scenario may affect this demand and therefore our forecasts may turn out to be inaccurate. For example, economic crises may restrict credit to the population, and uncertainties relating to employment may result in a delay in the

[**Table of Contents**](#TOC)

decision to acquire new products or services (such as broadband or Pay TV). As a result, it is possible that we may make larger investments based on demand forecasts that were necessary given actual demand at the relevant time, which may directly affect our cash flow.

Furthermore, improvements in economic conditions may have the opposite effect. For example, an increase in demand not accompanied by our investment in improved infrastructure may result in a possible loss of opportunity to increase our revenue or result in the degradation of the quality of our services.

***The transactions contemplated by the Oi Agreement may not be consummated, and if they are consummated, we may be unable to successfully integrate the assets and operations contemplated thereunder or to realize expected benefits.***

Our ability to consummate the transactions contemplated by the Oi Agreement is subject to certain factors outside our control, such as various closing conditions. These include customary closing conditions in addition to others that, despite being usually applicable to this type of transaction, are beyond our control, such as the requirement to obtain approvals from certain governmental regulatory authorities, including from CADE and ANATEL. Although we have obtained approval of the transactions from CADE and ANATEL as of the date of this annual report, our ability to consummate the transactions contemplated by the Oi Agreement is also subject to other factors that are beyond our control, such as the possibility of litigation that may arise relating to the regulatory approvals process or the Oi Agreement transactions generally. See "Item 4.Information on the Company—A. History and Development of the Company—Historical Background—Acquisition of UPI Mobile Assets of the Oi Group."

**In addition, achieving the targeted synergies of the Oi Agreement, such as operating and long-term strategic cost-savings, will depend in part upon whether we can integrate the assets and operations contemplated thereunder in an efficient and effective manner. We may not be able to accomplish this integration process smoothly or successfully. We and the Oi Group operate numerous systems, including those involving clients, spectrum, infrastructure, management information, accounting and finance, sales, billing, and regulatory compliance. Moreover, the integration of the assets and operations will require significant managerial resources, which may distract management's attention from day-to-day operations. Potential employee uncertainty and lack of focus during the integration process may also disrupt our business and result in undesired employee attrition. Our management's failure to successfully integrate the assets and operations contemplated by the Oi Agreement with our business could have a material adverse effect on our business, results of operations and financial condition. Our failure to realize the full extent, or any, of the anticipated benefits and synergies of the acquisition of assets and operations under the Oi Agreement, as well as any delays in the integration process, could have an adverse effect on our business, results of operations and financial condition.**

***We face risks associated with litigation.***

We are party to a number of lawsuits and other proceedings. An adverse outcome in, or any settlement of, these or other lawsuits could result in significant costs to us. In addition, our senior management may be required to devote substantial time to these lawsuits, which they could otherwise devote to our business. See "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal Proceedings."

#### Our results of operations may be negatively affected by changes to STFC or SMP rules.
We receive payments for the interconnection of calls in our fixed-line and mobile networks. Interconnection fees were set by ANATEL in December 2018 and February 2020 for STFC and SMP networks, respectively. See "Item 4. Information on the Company—B. Business Overview—Rates, Taxes and Billing—Interconnection fees." However, we cannot assure you that new mobile service plans will not be suspended by ANATEL, that current fixed-line or mobile interconnection fees remain the same, or that future negotiations on fixed-line or mobile interconnection rates will result in favorable terms or rates. If current fixed-line or mobile interconnection fees are canceled, or if fixed-line or mobile interconnection fees in the future are less favorable to us, our business, financial condition, revenues, results of operations and prospects may be adversely affected.

[**Table of Contents**](#TOC)

#### ANATEL has the authority to issue new regulations affecting many of our areas of operations.
ANATEL has the authority to issue new regulations affecting many of our areas of operations. Such new regulations could have an adverse effect on our operating results because: (1) ANATEL could significantly reduce the interconnection fees we are able to charge, thereby reducing our revenues (see "—Our results of operations may be negatively affected by changes to STFC or SMP rules"); (2) ANATEL may allow more favorable conditions for economic groups without significant market power; (3) the granting of new licenses may increase competition in our area from other operators, which could adversely affect our prices and/or market share, thereby reducing our revenues; (4) ANATEL may require that revenue received for the usage of the SMP network must be included in the calculation of renewing licenses costs; and (5) ANATEL's general plan of updating the regulations targets several areas of vital importance for our business (including both our fixed-line telephone and mobile businesses), which may cause either an increase in operating costs, an increase in competitive pressure, or a decrease in our revenues, among other adverse effects.

**For a detailed description of the regulations issued by ANATEL and their impact on our business, see "Item 4. Information on the Company—B. Business Overview—Regulation of the Brazilian Telecommunications Industry."**

***The industry in which we conduct our business is continually changing and evolving technologically, which demands adequate changes in the regulatory environment.***

The telecommunications industry is subject to rapid and significant technological changes. Our future success depends on our ability to anticipate and adapt in a timely manner to technological changes. We expect that new products and technologies will emerge and that existing products and technologies will be further developed.

The advent of new products and technologies could have a variety of consequences. These new products and technologies may reduce the price of our services by providing lower-cost alternatives and the creation of new digital services, such as the example of OTT service providers that provide voice and messaging services over IP. Also, new products and technologies may become superior to, and render obsolete, the products and services we offer and the technologies we use, thus requiring our constant investment in new technology and innovation.

**Such new technologies will demand changes in the regulatory environment, challenging both governmental agencies and telecommunication companies. Companies that provide OTT services, which have characteristics similar to telecommunications services, are currently not subject to the same rules as the telecommunications operators. This gap can bring additional challenges to the telecommunications industry, as current developments in the regulatory framework for OTTs are inconsistent and still unclear.**

***We are subject to certain risks related to conditions and obligations imposed by ANATEL for the use of the spectrum needed for the 4G and 5G services we offer.***

In 2012, we acquired 40MHz on the 2.5GHz to 2.69GHz frequencies for the amount of R$1.05 billion. In order to meet the coverage requirements, we had the obligation of implementing 4G coverage in 1,094 cities by December 31, 2017. The remaining coverage commitments in cities with less than 30,000 inhabitants could be fulfilled with other frequency bands until December 31, 2019. Verification of compliance with these targets is controlled by ANATEL and, regarding the cities with less than 30,000 inhabitants, is in progress.

Regarding the 700MHz spectrum, ANATEL has allocated the band for the provision of fixed, mobile and broadband services. On September 30, 2014, we acquired 20 MHz (10+10 MHz) with nationwide coverage, for R$1.92 billion, at the minimum price, plus R$904 million for the band cleaning (migration of broadcasters that currently occupy the band) and interference management. According to the auction rules, the winning bidders were responsible for financing and managing the band cleaning process (Analog TV switch off) which was implemented through a legal entity specifically incorporated for this purpose, as set forth in the bidding process and applicable regulations (EAD). Since June 2019, all Brazilian municipalities are ready to activate LTE coverage in the 700 MHz band.

[**Table of Contents**](#TOC)

In November 2021, ANATEL held the largest spectrum auction in its history, which included 4G and, for the first time, 5G blocks, with 700 MHz, 2.3 GHz, 3.5 GHz and 26 GHz lots. On that occasion, we acquired 3.5 GHz and 26 GHz national licenses (100 MHz and 600 MHz bandwidths, respectively). We also won regional 2.3 GHz licenses, with 50 MHz bandwidth in the southeast region of Brazil (except São Paulo state and PGO Sector 3) and 40 MHz bandwidth in São Paulo state and in the north and mid-west regions of Brazil (except PGO Sectors 22 and 25). These acquired licenses, which we purchased for a total of R$4.45 billion, of which R$0.9 billion is related to licenses and the remaining amount related to the obligation described below. The licenses ensure we have the required spectrum to provide 5G services, and are valid for 20 years (renewable under the then-existing legal conditions at the expiration of this term).

ANATEL also set forth obligations to be fulfilled by the winners of the 5G spectrum auction. For the 2.3 GHz and 3.5 GHz spectrum bands, these obligations include coverage commitments, the deployment of fiber optic backbone networks in locations with little or no connectivity infrastructure, the implementation of the Integrated and Sustainable Amazon Program (*Plano Amazônia de Integração e Sustentabilidade*), and devising a project for a private communications network reserved for the Brazilian federal government, as well as the funding activities related to the migration of satellite TV services from the C-band to the Ku-band. Winners of the 26 GHz spectrum bands, in turn, will have to invest in connectivity projects aimed at selected public schools throughout Brazil.

The targets established by ANATEL for the fast-paced implementation of networks could be impacted by (1) our ability to obtain licenses for the construction of new sites at the speed necessary to achieve the coverage targets, (2) the capacity of our suppliers to deliver the equipment necessary for this expansion, which may increase the price of such equipment, and (3) lack of qualified resources to meet the expected implementation pace.

**If we are not able to meet targets and obligations set forth in the bid documents, ANATEL may execute our bank guarantees, we may be subject to fines and/or have our licenses to operate these frequencies revoked, negatively affecting our business and results of operations. Additionally, the inefficient use of any frequency may lead to the loss of the usage license. Furthermore, ANATEL may also impose new targets, conditions and/or obligations on us that we are not able to predict (see "—A review of our concession agreements and/or the new telecommunications regulatory framework in Brazil could have a materially adverse effect on our operations"). Any of the above factors could have a material adverse effect on our operations and financial condition.**

#### Our sales could be suspended as a result of issues with the quality of our services.
**ANATEL and other judicial and administrative agencies have the authority to suspend our sales in an attempt to improve the overall quality of telecommunications services. Sales suspensions are generally applied to the services for which there have been complaints by consumers and the consumer protection agencies. When applied, the suspension is temporary and usually lifted once the company presents an action plan for improvement. In July 2012, ANATEL suspended mobile service sales by our competitors, Oi, Claro and TIM, as a result of a considerable increase in consumer complaints. The suspensions lasted about 20 days and ANATEL requested that all telecommunications companies, including us, present an action and investment plan to improve the mobile network. Although our action plan was approved by ANATEL in September 2012, if a similar increase in customer complaints occurs in the future we may face suspension of one or more of our services until a new plan can be presented to and approved by ANATEL, which may materially affect our business and results of operations.**

***We are subject to the risk of noncompliance with data privacy and protection laws, which may lead to sanctions, including financial penalties.***

In 2018, the President of Brazil approved Brazilian Law No. 13,709/2018, named the General Personal Data Protection Law (*Lei Geral de Proteção de Dados*), or the LGPD, which came into force on September 18, 2020, a comprehensive data protection law establishing the general principles and obligations that apply across multiple economic sectors and contractual relationships. Certain aspects of the LGPD will be subject to further regulation by the National Data Protection Authority (*Autoridade Nacional de Proteção de Dados*, or the ANPD, in accordance with the ANPD's Ordinances No. 11/2021 and 35/2022.

[**Table of Contents**](#TOC)

The LGPD establishes detailed rules for the collection, use, processing and storage of personal data in all economic sectors, regardless of whether data is collected in a digital or physical environment. In general, our services and processes depend on personal data. The way in which we collect, store and manage this data must comply with the provisions of the LGPD. In addition, the administrative sanctions provided for in the LGPD (arts. 52, 53 and 54), came into force on August 1, 2021, pursuant to Law No. 14,010/2020. Sanctioning is expected to follow ANPD Regulation No. 1/2021, which was approved following public notice and comment by the ANPD's board of directors. In the event of a violation of the LGPD, we may be subject to (1) legal notices and the required adoption of corrective measures, (2) fines of up to 2% of our or our economic group's revenues up to a limit of R$50.0 million per infraction, (3) publication of the infraction following confirmation of its occurrence, (4) the blocking and erasing of personal data involved in the infraction, (5) partial or complete suspension of the infringing processing activities for up to one year and (6) partial or complete prohibition to engage in processing activities.

We may be held liable for material, punitive, individual or collective damages to the data subjects due to the processing of their personal data and could be held individually or jointly liable for material, punitive, individual or collective damages caused by us, our subsidiaries, service providers that may process personal data on our behalf or our affiliates due to non-compliance with the obligations set forth by the LGPD and other laws and regulations in force that address data protection, which may adversely affect our reputation and results and, consequently, the value of our shares.

Failure or insufficiency to adopt efficient measures to protect personal data or failure to maintain compliance with the LGPD may lead to the application of fines, obligation to disclose relevant incidents to the market, obligation to eliminate personal data from relevant databases and suspension of access to our databases and prohibition of our activities related to the processing of compromised data. We also may be subject to sanctions not related to the supervision of the ANPD, since consumer protection authorities and the Public Prosecutor's Office have already been active in pursuing data privacy violations even before the LGPD became effective. Accordingly, failure to protect personal data processed by us or any failure to implement adequate data protection measures in response to applicable legislation may subject us to additional costs such as the payment of fines and indemnities, implementation of adjustment measures, and loss of business, in addition of civil sanctions, which may adversely affect our reputation and results.

**In addition, the application of administrative sanctions under other laws dealing with privacy and data protection issues might be possible, such as the Consumer Protection Code and the Brazilian Civil Rights Framework for the Internet. These administrative sanctions may be imposed by other public authorities, such as the Public Prosecutors' Offices, the National Consumer Secretariat and consumer protection agencies. We may also be subject to liability in the civil sphere for violation of these laws. Sanctions imposed against us by these authorities may also adversely affect our reputation and results and, consequently, the value of our ADSs and common shares.**

***Internet regulation in Brazil is still limited and several legal issues related to the Internet are uncertain.***

In 2014, Brazil enacted a law, which we refer to as the Brazilian Civil Rights Framework for the Internet (*Marco Civil da Internet*), setting forth principles, guarantees, rights and duties for the use of the Internet in Brazil, including provisions about internet service provider liability, internet user privacy and internet neutrality. In May 2016, further regulations were passed in connection with the referred law. The administrative penalties imposed by the Brazilian Civil Rights Framework for the Internet include notification, fines (up to 10% of the revenues in Brazil of the relevant entity's economic group in the preceding fiscal year) and suspension or prohibition from engaging in data processing activities. The Brazilian Civil Rights Framework for the Internet also determines joint and several liability between foreign parent companies and local Brazilian subsidiaries for the payment of fines that may be imposed for breach of its provisions. Administrative penalties may be applied cumulatively. Daily fines may be imposed in judicial proceedings, as a way to compel compliance with a Brazilian court order. If for any reason a company fails to comply with the court order, the fine can reach significant amounts. We may be subject to liability under these laws and regulations should we fail to adequately comply with the Brazilian Civil Rights Framework.

However, unlike in the United States, little case law exists around the Brazilian Civil Rights Framework for the internet and existing jurisprudence has not been consistent. Legal uncertainty arising from the limited guidance provided by current laws in force allows for different judges or courts to decide very similar claims in different ways and establish contradictory jurisprudence. This legal uncertainty allows for rulings against us and could set adverse precedents, which individually or in the aggregate could seriously harm our business, results of operations and financial condition. In addition, legal uncertainty may harm our customers' perception and use of our service.

***Some of our debt agreements contain covenants, key performance indicators, and targets; as such, any default or failure to reach such targets under such debt agreements may have a material adverse effect on our financial condition and cash flows.***

Some of our existing debt agreements contain restrictions and covenants and require the maintenance or satisfaction of specified financial metrics and tests. Failure to comply with or fulfill any of these restrictions, covenants, financial metrics or financial tests could result in a default under these agreements, which would have a material adverse effect on our financial condition.

***We are subject to environmental laws and regulations. Failure to comply with governmental laws and regulations could subject us to penalties that could have an adverse effect on our business and reputation.***

Our operations and properties are subject to a variety of environmental laws and regulations governing, among other subjects, environmental licensing and registries, protection of flora and fauna, air emissions, waste management and remediation of contaminated areas. Our failure to comply with present and future requirements, or to identify and manage new or existing environmental liabilities, could cause us to incur substantial costs, including investigation and remediation costs, indemnification, compensation, conduct adjustments, fines, suspension of activities and other penalties, investments to upgrade our facilities or change our processes, as well as damages to the company´s reputation. The identification of presently unidentified environmental issues, change in evaluation criteria by regulatory agencies, enactment of more restrictive laws and regulations or other unanticipated events may arise in the future and result in material environmental liabilities and related costs. The occurrence of any of the foregoing could have a material adverse effect on our business, results of operations, assets and financial condition.

***Man-made or natural disasters, including extreme weather conditions due to climate change (high temperatures, floods, thunderstorms) or other unexpected events could adversely affect networks, systems, infrastructure and service continuity.***

Our operations may be suspended or interrupted for an indeterminate period in case of adverse events, such as a result of damages to our transmission bases, natural disasters, climate change or other environmental events or natural or man-made disasters, including fire, explosion, storms, geopolitical disruptions, civil unrest or health crises (such as the COVID-19 pandemic) or any other unexpected events.

Climate change poses a number of potential risks for telecommunications operators like us, from both a physical and regulatory perspective. Global climate change may exacerbate the severity and frequency of natural disasters. The rising intensity and frequency of occurrence of storms, heatwaves and wildfires could increase the damage to our infrastructure and failures of our wireline and wireless networks caused by such natural disasters. Should severe natural disasters occur in quick succession, we may not have sufficient resources to repair and restore our infrastructure in a timely and cost-effective manner. The increase in the likelihood of our infrastructure being damaged by natural disasters could have a material adverse impact on our operations.

Rising mean temperatures could increase our operating costs due mostly to the increase in refrigeration needs of network equipment. High temperatures also can affect the telecommunication equipment producing failures, write-offs and early retirement and therefore increase the risk of service disruption; therefore, cooling is essential.

An increase in energy costs is one of our main climate-related risks (transitional risk). The Telecom sector is not especially dependent on fossil fuels but is very dependent on electricity consumption for its networks, so an increase in electricity prices due to a shortage of natural resources could have a significant impact on our energy-related operating expenses.

If we are unable to mitigate or prevent any such damage in the event of a natural or man-made disaster and any other unexpected events, the suspension or interruption of our operations could have an adverse effect on the continuity of our operations, our financial results and compliance with applicable regulations. To manage these risks, we promote energy efficiency programs, renewable energy plans and distributed energy generation, in addition to having a dedicated business continuity department guided by the Global Business Continuity Regulation, which prescribes guidelines on the preventive management of risks, and which supports the resilience of our operations against potential interruptions.

#### Companies operating in the telecommunication industry, including us, may be harmed by restrictions regarding the deployment and maintenance of network infrastructure.
Currently, hundreds of municipal laws in Brazil limit the installation of new antennas for mobile service. This scenario has been a barrier to the expansion of mobile networks. Those laws are meant to regulate issues related to zoning and the alleged effects of the

[**Table of Contents**](#TOC)

radiation and radio frequencies of the antennas. Despite the existence of a federal law enacted in 2015, that addresses this issue by establishing new guidelines to create a consolidated plan for the installation of antennas, as long as the municipal laws remain unchanged, the risk of non-compliance with regulations and of having services of limited quality in certain areas continues to exist.

Additional antenna installation is also limited because of concerns that radio frequency emissions from base stations may cause health problems and other environmental impacts. These concerns could have an adverse effect on the wireless communications industry and, possibly, expose wireless providers, including us, to litigation. Based on information from the WHO we are not aware of any evidence in the latest medical research that conclusively establishes any relationship between radio frequency emissions of base stations and health concerns. Perceived risks may, however, delay the expansion of our network if we experience problems in finding new sites, which in turn may delay expansion and affect the quality of our services. For instance, in May 2009, Law No. 11,934/2009 was enacted, which limits the exposure for fields with frequencies of up to 300 GHz. The new law uses the exposure limits determined by the International Commission on Non-Ionizing Radiation Protection and recommended by the WHO and restricts the installation of new antennas.

New laws and regulations may also create additional restrictions on our transmission infrastructure, which in turn, could have an adverse effect on our business. Health concerns regarding the effects of radio frequency emissions may also discourage the use of mobile telephones and may result in the adoption of new measures by governments or any other regulatory interventions, any of which could materially and adversely affect our business, results of operations and financial condition.

***Changes in taxes and other assessments may adversely affect us and our shareholders.***

The legislatures and tax authorities in the tax jurisdictions in which we operate regularly enact reforms to the tax and other assessment regimes to which we and our customers are subject. Such reforms include changes in tax rates and, occasionally, enactment of temporary taxes, the proceeds of which are earmarked for designated governmental purposes. In addition, the interpretation of tax laws by courts and taxation authorities is constantly evolving. In Brazil, the tax system is highly complex and the interpretation of the tax laws and regulations is commonly controversial. The effects of these changes and any other changes that result from the enactment of additional tax reforms or changes to the manner in which current tax laws are applied cannot be quantified and there can be no assurance that any such reforms or changes would not have an adverse effect upon our business.

The Brazilian government regularly implements changes to tax regimes that may increase the tax burden on us, our subsidiaries and jointly-controlled entities and their respective customers. These changes include modifications in the rate of assessments and the enactment of new or temporary taxes, the proceeds of which are earmarked for designated governmental purposes.

In addition, the new administration proposed during the presidential campaign to revoke the income tax exemption over the distribution of dividends, which, if promulgated, would increase tax expenses associated with any dividends or distributions, which could impact our ability to pay dividends and receive future dividends from our subsidiaries. Any purported tax reform, if proposed and implemented, may also significantly impact our business. Any future changes in tax policy or laws may adversely affect our business, financial condition and results of operations.

***The ongoing war between Russia and Ukraine may have a material adverse effect on the global and Brazilian economies as well as on us.***

The ongoing war between Russia and Ukraine has provoked strong reactions from the United States, the UK, the EU and various other countries around the world, including from the members of NATO. Following Russia's invasion of Ukraine beginning on February 24, 2022, the United States, the UK, the EU and other countries announced broad economic sanctions against Russia, including financial measures such as freezing Russia's central bank assets and limiting its ability to access its U.S. dollar reserves. The United States, the EU and the UK have also banned people and businesses from dealings with the Russian central bank, its finance ministry and its wealth fund. Selected Russian banks have also been removed from the Swift messaging system, which enables the smooth transfer of money across borders. Other sanctions by the UK include major Russian banks being excluded from the UK financial system, stopping them from accessing sterling and clearing payments, major Russian companies and the state being stopped from raising finance or borrowing money on the UK markets, and the establishment of limits on deposits Russians can make at UK banks. The United States, the EU and the UK adopted personal measures, such as sanctions on individuals with close ties to Mr. Putin, and placed visa restrictions on several oligarchs, as well as their family members and close associates, and freezing of assets.

[**Table of Contents**](#TOC)

While the precise effect of the ongoing war and these sanctions on the Russian and global economies remains uncertain, they have already resulted in significant volatility in financial markets, depreciation of the Russian ruble and the Ukrainian hryvnia against the U.S. dollar and other major currencies, as well as an increase in energy and commodity prices globally. Should the conflict continue to increase, markets may face continued volatility as well as economic and security consequences including, but not limited to, supply shortages of different kinds, further increases in prices of commodities, including piped natural gas, oil and agricultural goods, among others.

There remains considerable uncertainty as to the outcome of the war and its impact on the global economy, financial markets and the prices and supply of commodities and other products and services globally. The potential consequences of the war for us include, without limitation:

● The U.S. dollar may appreciate sharply which could increase the price of goods and services on which we depend for which we are required to pay in U.S. dollars, as well as increase the pressure on our margins and prices generally.

● Given that Russia and Ukraine are among the largest grain exporters in the world, a continuation of the conflict could result in increased inflation in Brazil and in measures by the Brazilian government and the Brazilian Central Bank to contain inflation, such as raising the basic interest rate, which could materially impact the cost of debt and third-party capital for our financing and investing activities.

● Inflation resulting from the ongoing COVID-19 crisis has been compounded by the conflict between Russia and Ukraine. Inflation makes it more difficult for us to conduct our financial planning, and increases the capital needed to fund our activities and our credit risk exposure. Measures by the Brazilian government and the Brazilian Central Bank to contain inflation, such as raising the basic interest rate, could materially impact the cost of debt and third-party capital for our financing and investing activities.

● A recession of the Brazilian and/or global economies as a result of the aforementioned developments could also have a material adverse effect on our business.

In addition, this conflict can exacerbate supply chain disruption, which was borne out of the COVID-19 pandemic and contributed to inflationary pressures throughout the world, leading to higher interest rates and financing issues.

Other potential consequences include, but are not limited to, growth in the number of popular uprisings in the region, increased political discontent, especially in the regions most affected by the conflict or economic sanctions, increased cyberterrorism activities and attacks, an exodus from regions close to the areas of conflict and an increase in the number of refugees fleeing across Europe, among other unforeseen social and humanitarian effects.

The effects of the war between Russia and Ukraine are ongoing, and its continuation or escalation could precipitate or aggravate the other risk factors identified in this annual report on Form 20-F, which in turn could further materially and adversely affect our business, financial condition, liquidity, results of operations and profitability, including in ways not currently known or considered by us to present material risks.

While as of the date of this annual report there have not been any material impacts from the ongoing war between Russia and Ukraine on our business, we are continuously monitoring the developments to assess any potential future impacts that may arise as a result of the ongoing war. The adverse effects—global or localized—of the ongoing war between Russia and Ukraine, and/or economic sanctions and import and/or export controls to be imposed by the United States, the UK, the EU or others, and their adverse effects on the wider global economy and market conditions could have a material adverse effect on our business, financial condition and results of operations.

#### Risks Relating to the Common Shares and the ADSs

#### Holders of our ADSs may face difficulties in serving process on or enforcing judgments against us and other persons.
We are organized under the laws of Brazil, and all of our executive officers and our independent public accountants reside or are based in Brazil. Also, four of our 12 board members reside or are based in Brazil. Substantially all of our assets are located in Brazil. As a result, it may not be possible for holders of the ADSs to effect service of process upon us or these other persons within the United States or other jurisdictions outside Brazil or to enforce any judgments obtained in the United States or other jurisdictions outside Brazil against us or such other persons. Because judgments of U.S. courts for civil liabilities based upon the U.S. federal securities laws may only be enforced in Brazil if certain conditions are met, holders may face greater difficulties in protecting their interests due to actions by us, our board members or executive officers than would shareholders of a U.S. corporation.

#### Holders of our ADSs are not entitled to directly attend shareholders' meetings and may only vote through the depositary.
Under Brazilian law, only shareholders registered as such in our corporate books may attend shareholders' meetings. All common shares underlying our ADSs are registered in the name of the depositary. A holder of ADSs, accordingly, is not entitled to directly attend shareholders' meetings. Holders of our ADSs may exercise their limited voting rights with respect to our common shares represented by the ADSs indirectly, and only in accordance with the deposit agreement relating to the ADSs. There are practical limitations on the ability of ADS holders to exercise their voting rights due to the additional steps involved in communicating with ADS holders. For example, we are required to publish a notice of our shareholders' meetings in certain newspapers in Brazil. Holders of our shares can exercise their right to vote at a shareholders' meeting by attending the meeting in person or voting by proxy. By contrast, holders of our ADSs will receive notice of a shareholders' meeting by mail from the ADR depositary following our notice to the ADR depositary requesting the ADR depositary to do so. To exercise their voting rights, ADS holders must instruct the ADR depositary on a timely basis. This voting process will take longer for ADS holders than for direct holders of our shares.

We cannot assure you that holders will receive the voting materials in time to ensure that such holders can instruct the depositary to vote the shares underlying their respective ADSs. In addition, the depositary and its agents are not responsible for failing to carry out holder's voting instructions or for the manner of carrying out your voting instructions. This means that holders may not be able to exercise their right to vote and may have no recourse if our shares held by such holders are not voted as requested.

***Holders of our ADSs or common shares might be unable to exercise preemptive rights with respect to the common shares unless there is a current registration statement in effect which covers those rights or unless an exemption from registration applies.***

Under Brazilian law, if we issue new shares for cash as part of a capital increase, we generally must grant our shareholders the right to purchase a sufficient number of shares to maintain their existing ownership percentage. Rights to purchase shares in these circumstances are known as preemptive rights. Holders of our ADSs or common shares in the United States will not be able to exercise any preemptive rights unless a registration statement under the U.S. Securities Act of 1933, as amended, or the Securities Act, is effective with respect to that future issuance of shares, or an exemption from the registration requirements of the Securities Act is available. We are not obligated to file a registration statement. Unless we file a registration statement or an exemption from registration applies, holders of our ADSs may receive only the net proceeds from the sale of their preemptive rights by the depositary, or if the preemptive rights cannot be sold, they will lapse and they will not receive any value for them. For more information on the exercise of these rights, see "Item 10. Additional Information—B. Memorandum and Articles of Association—Description of our Bylaws—Preemptive Rights."

#### An exchange of ADSs for common shares risks the loss of certain foreign currency remittance and Brazilian tax advantages.
Beginning on March 30, 2015, the different forms of foreign portfolio investments in Brazil, including investments via depositary receipts, have been regulated by CMN Resolution No. 4,373/2014, or Resolution No. 4,373, which revoked the former rule that had been in effect for the preceding 15 years (CMN Resolution No. 2,689/2000), and by Law No. 4,131/1962. Law No. 4,131/1962 was recently significantly amended by Law No. 14,286/2021, which became effective on December 31, 2022. However, relevant aspects of Law No. 14,286/2021, such as those pertaining to foreign portfolio investments in Brazil, remain subject to regulation by the Brazilian Central Bank, such that, as of the date of this annual report, we are unable to foresee the effects it will have on the Company.

**Resolution No. 4,373 regulates the issuance of depositary receipts in foreign markets in respect of shares of Brazilian issuers. Pursuant to this regulation, the ADSs benefit from a certificate of foreign capital registration, which permits Citibank N.A., as** 

[**Table of Contents**](#TOC)

**depositary, to convert dividends and other distributions with respect to common shares into foreign currency and to remit these proceeds abroad. Holders of ADSs who exchange their ADSs for common shares will then be entitled to rely on the depositary's certificate of foreign capital registration for five business days from the date of exchange. Thereafter, if acting as an individual investor, they will not be able to remit non-Brazilian currency abroad unless they obtain their own certificate of foreign capital registration, constituting a Brazilian financial institution as representative, or unless they qualify under Resolution No. 4,373, which entitles certain investors to buy and sell shares on Brazilian stock exchanges without obtaining separate certificates of registration. Further rules may be issued by CVM and by the Central Bank to regulate foreign investments in ADSs, including with regard to the exchange of ADSs for common shares and the remittance of funds arising from the sale of these common shares.**

**If holders of ADSs do not qualify under Resolution No. 4,373, they will generally be subject to less favorable tax treatment with respect to our common shares. There can be no assurance that the depositary's certificate of registration or any certificate of foreign capital registration obtained by holders of ADSs will not be affected by future legislative or regulatory changes, or that additional Brazilian law restrictions applicable to their investment in the ADSs may not be imposed in the future. Considering, however, that one of the premises of Law No. 14,286/21 is to grant equal treatment to foreign capital entering Brazil and to Brazilian capital, the scenario regarding foreign investment should be made simpler than the rules currently in force.**

***Holders of our common shares will be subject to, and holders of our ADSs could be subject to, Brazilian income tax on capital gains from sales of common shares or ADSs.***

Law No. 10,833/2003, or Law No. 10,833, provides that gains on the disposition of assets located in Brazil by nonresidents of Brazil, whether to other nonresidents or to Brazilian residents, will be subject to Brazilian taxation. The common shares are expected to be treated as assets located in Brazil for purposes of the law, and gains on the disposition of common shares, even by nonresidents of Brazil, are expected to be subject to Brazilian taxation.

Based on the fact that the ADSs are issued and registered abroad, we believe that gains on the disposition of ADSs made outside of Brazil by nonresidents of Brazil to another non-Brazilian resident would not be subject to Brazilian taxation, since they would not fall within the definition of assets located in Brazil for purposes of Law No. 10,833. However, considering the generic and unclear scope of Law No. 10,833 and the absence of judicial/administrative court rulings in respect thereto, we cannot be assured that such an interpretation of this law will prevail in the courts of Brazil.

In case of any assessment by the Brazilian tax authorities, the gains arising from the disposal of ADSs made are subject to capital gain tax in Brazil at (i) progressive rates ranging from 15% to 22.5%, or (ii) 25%, if the non-Brazilian holder is located in a tax haven jurisdiction. See "Item 10. Additional Information—E. Taxation—Brazilian Tax Considerations."

#### Certain Factors Relating to our Controlling Shareholder

#### Our controlling shareholder has power over the direction of our business.
Telefónica, our controlling shareholder, and its affiliates currently own, directly and indirectly, approximately 74.20% of our total capital stock. See "Item 7. Major Shareholders and Related Party Transactions—A. Major Shareholders" and "Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions." As a result of their share ownership, Telefónica and its affiliates can decide most of the matters that require shareholder approval.

#### Item 4. Information on the Company
&nbsp;&nbsp;&nbsp;&nbsp;A. **History and Development of the Company** 

#### General
We were incorporated on May 22, 1998, as a corporation (*sociedade anônima*) organized under the laws of the Federative Republic of Brazil, as a result of the restructuring and privatization of Telecomunicações Brasileiras S.A. and its operating subsidiaries, or Telebrás, which monopolized the provision of public telecommunications services in virtually all areas of Brazil prior to 1998. We were incorporated under the name Telesp Participações S.A. and after subsequent reorganizations, we were named Telecomunicações de São Paulo S.A. – TELESP. After our merger with Vivo Participações in October 2011, we changed our corporate name to Telefônica Brasil S.A.

[**Table of Contents**](#TOC)

On September 18, 2014, we entered into a stock purchase agreement with Vivendi S.A. to acquire all of the shares of GVT Participações S.A., or GVT, the controlling shareholder of Global Village Telecom S.A., or Operating GVT, which was approved by our board of directors on the same date. Pursuant to Brazilian law, the transaction required approval by both ANATEL and CADE. On December 22, 2014, ANATEL approved the transaction and imposed certain obligations, that included (1) the maintenance of current GVT services and plans within the same geographic scope in which GVT previously operated, requiring, in addition, that the successor company expand its operations to at least ten new municipalities within three years beginning on January 26, 2015; and (2) the waiver of the STFC license held by GVT within 18 months of ANATEL's decisions, since the same economic group cannot hold more than one STFC license in the same geographic area. Telefônica has satisfied both obligations. On March 25, 2015, CADE provisionally approved the GVT acquisition, subject to a series of obligations imposed to prevent any undesired concentration effects of the merger. Such obligations require that we:

● Maintain, for at least three years, the current geographical coverage for STFC, SCM and SeAC services;

● Maintain, for at least three years, the current average broadband speed for GVT's customers on a nationwide basis. The reference as of December 2014 is 15.1 Mbps;

● Maintain, for at least three years, the current average broadband speed for GVT's customers in São Paulo. The reference as of December 2014 is 18.25 Mbps; and

● Do not exchange, directly or indirectly, classified information, strategic or competitively sensitive information with any other company or between management and representative responsible for subsidiaries of Vivendi group, the Telefónica group and the Telecom Italia group related to its operations in the Brazilian market.

In November 2015, ANATEL consented to our corporate reorganization involving Telefônica Brasil S.A., GVT Participações S.A. and its subsidiaries. The approval was subject to certain conditions such as the end of overlap licenses of STFC, SCM and SeAC within 18 months and the obligation to present a list of all assets from the companies incorporated in our STFC (Sector 31, Region III) concession area, confirming the absence of reversible assets burdened judicially (by means of a negative certificate), or in case of attachment, present the appropriate requests for replacement. On March 14, 2016, the corporate reorganization was approved by our board of directors and was completed on April 1, 2016, after the approval by an extraordinary shareholders meeting of the relevant companies.

On July 3, 2017, Telefônica Data S.A., or TData, a wholly-owned subsidiary of the Company, acquired all the shares of capital stock of Terra Networks Brasil S.A ., or Terra, from SP Telecomunicações Participações Ltda., or SP Telecom, one of the controlling shareholders of the Company. The purpose of the Terra Networks Transaction is to expand and integrate our offering of digital services, in order to provide additional value to our customer base and TData's. Effective as from December 1, 2018, TData was merged into the Company as part of a corporate restructuring. See "—Historical Background—Restructuring Involving TData" for more information.

In March 2020, the Company expressed interest in acquiring, jointly with TIM S.A. and Claro S.A., part of the UPI mobile assets of Oi S.A., an acquisition that would reach its closing on April 20, 2022. On that date, all the shares of Garliava RJ Infraestrutura e Redes de Telecomunicações S.A., a special purpose company, to which the mobile assets of Oi Group assigned to the Company had been contributed, in accordance with the segregation plan stated in the Oi Agreement.

We are registered with the CVM as a publicly held company and our stock is traded on the B3 under the ticker "VIVT3". We are also registered with the SEC in the United States and our ADSs are traded on the NYSE under the ticker "VIV" (formerly "TSP"). Our headquarters are located at Avenida Engenheiro Luis Carlos Berrini, 1376, 04571-936, São Paulo, SP, Brazil. Our telephone number is 55-11-3430-3687 and our website is www.telefonica.com.br/ir. The information on our website is not a part of this annual report on Form 20-F.

**As of December 31, 2022, we had 1,663,556,731 outstanding common shares (excluding treasury shares), with no par value per share. Our shareholders' equity amounted to R$68.5 billion as presented in our audited financial statements prepared in accordance with IFRS.**

#### Historical Background

#### Corporate Restructuring Involving the Company and Vivo Participações
On July 28, 2010, our parent company, Telefónica, reached an initial agreement with Portugal Telecom for the acquisition of 50% of the share capital of Brasilcel, N.V., or Brasilcel. As a result of this transaction, Telefónica held 100% of Brasilcel's share capital. At the time, Brasilcel held approximately 60% of Vivo Participações' share capital. On December 21, 2010, Brasilcel was incorporated into Telefónica.

Due to the acquisition of control of Vivo Participações, on February 16, 2011, Telefónica, through its subsidiary SP Telecomunicações Ltda., or SP Telecom, launched a public offer for the common shares of Vivo Participações (its only voting shares) held by minority shareholders. As a result of the public offer, on March 18, 2011, SP Telecom acquired 10,634,722 common shares of Vivo Participações, representing 2.66% of its shares, resulting in the Telefónica group's participation of 62.1% of Vivo Participações.

On December 27, 2010, the boards of Directors of Vivo Participações and Telefônica Brasil approved the terms and conditions of a corporate restructuring, which provided for the merger of the shares issued by Vivo Participações in Telefônica Brasil. The corporate restructuring was approved by ANATEL on March 24, 2011, and on April 27, 2011, the shareholders of Vivo Participações and Telefônica Brasil approved the merger of the shares issued by Vivo Participações in Telefónica. On June 14, 2011, the board of directors of both companies approved a second corporate restructuring, in which Vivo Participações became our wholly-owned subsidiary. The terms and conditions of the second corporate restructuring were unanimously approved by the shareholders of both companies on October 3, 2011. Vivo Participações was incorporated into us, and the holders of Vivo Participações' merged shares received new shares of the company.

Due to the merger of Vivo Participações into us, our capital was increased by R$31.2 billion, reflecting the economic value of the shares issued as a result of the merger. The merger did not change the identity of the controlling shareholders of the companies.

In addition, as a result of this merger, on July 6, 2011, Vivo Participações submitted a statement to the SEC to cancel the registration of its American Depositary Shares, or ADS, program, since all its ADSs were converted into ADSs of Telefônica Brasil. The SEC approved the deregistration on July 7, 2011.

A third stage of the corporate restructuring was approved by ANATEL on August 16, 2011. On October 3, 2011, our shareholders approved the merger of Vivo Participações in the USA and Telefônica Brasil absorbed the assets of Vivo Participações, extinguishing Vivo Participações, which simplified and further rationalized our cost structures. On the same date, we changed our telecommunications name from São Paulo S.A. – TELESP to Telefônica Brasil S.A., to reflect our national operations. On October 18, 2011, ANATEL approved the transfer of the authorization for the provision of SMP services in the state of Minas Gerais from Vivo Participações to Vivo.

**As a result of this name change, the ticker symbols for our shares were also changed from October 6, 2011 (including), from TLPP3, for common shares, and TLPP4, for preferred shares, to VIVT3 and VIVT4, respectively, with the subsequent change of our trading name to TELEF BRASIL. Our ticker symbol for ADRs on the NYSE was changed to VIV, from TSP.**

#### Acquisition of GVT
On September 18, 2014, we signed a share purchase agreement with Vivendi and some of its subsidiaries, or collectively, Vivendi, and with GVTPar, Telefónica, S.A. and GVT Operacional, under which we agreed to buy all shares of GVTPar, the controlling shareholder of GVT. This acquisition was approved by our board of directors on September 18, 2014.

As consideration for the acquisition, we agreed to pay a portion of the price in cash and a portion in cash, in the form of our common and preferred shares, as follows: (1) €4,663,000,000 to be paid in cash on the closing date, as adjusted under the terms of the share purchase agreement, and (2) our common and preferred shares in the amount of 12% of our total capital after the capital increase contemplated in the share purchase agreement and the merger of GVTPar shares in us. The full consideration was paid upon completion of (A) a capital increase, the proceeds of which were used to pay the cash consideration described in (1) above, and (B) the merger of GVTPar shares in us.

On December 22, 2014, ANATEL approved the transaction and imposed certain obligations, which we believe did not compromise the terms of the acquisition of GVT or its value. On March 25, 2015, CADE's administrative court approved the

[**Table of Contents**](#TOC)

transaction on the basis of certain confidential commitments offered by us and Vivendi S.A. Commitments include the execution of two merger control agreements: the first between CADE and the second between CADE and Vivendi S.A.

On March 25, 2015, our board of directors approved the public offering of shares, including shares in the form of ADSs, in accordance with a capital increase of R$15,812,000,038.03, by issuing 121,711,240 common shares, at the price of R$38.47 and 236,803,588 preferred shares, at the price of R$47.00, as well as 6,282,660 preferred shares according to the exercise of the excessive allotment option. On May 28, 2015, our shareholders approved the ratification of the Share Purchase Agreement and Other Agreements, signed by the Company, as Buyer, and Vivendi S.A. and its subsidiaries, Société d'Investissements et de Gestion 108 SAS and Société d'Investissements et de Gestion 72 S.A., as Sellers, for which all shares issued by GVTPar, a shareholder of Global Village Telecom S.A., were acquired by us.

Therefore, as provided for in the share purchase agreement, we paid a portion of GVT's spot acquisition price with cash, receiving shares of GVTPar and GVT Operator, and another portion in shares, to FrHolding108 as a result of the merger of GVTPar's shares in us, representing 12% of our share capital after the merger.

On June 24, 2015, the transaction for the exchange of shares between Telefónica and Société d'Investissements et de Gestion 108 SAS, a company controlled by Vivendi S.A. was completed, through which FrHolding108 transferred to Telefónica 76,656,559 shares representing 4.5% of our share capital, including 68,597,306 common shares representing 12% of this class of shares and 8,059,253 preferred shares representing 0.72% of this class of shares, in exchange for 1,110,000,000 shares representing 8.2% of the common shares of Telecom Italia, S.p.A., previously held by Telco TE, S.p.A., a subsidiary of Telefónica.

On July 29, 2015, Vivendi S.A. sold 67.9 million preferred shares, representing 4% of our share capital. On the same day, Telefónica S.A. announced that it had signed an agreement with Vivendi's subsidiary, Société d'Investissements et de Gestion 108 SAS, through which Telefónica undertook to deliver 46.0 million of its treasury shares, representing 0.95% of its share capital, in exchange for 58.4 million preferred shares of Telefônica Brasil, S.A., (received by Société d'Investissements et de Gestion 108 SAS. in the context of the acquisition of GVT Participações, S.A.). On September 16, 2015, the stock exchange was completed. Consequently, Telefónica S.A.'s interest in the Company increased 5.2% in relation to the total preferred shares of the Company and 3.5% in relation to the company's total capital. On the other hand, SIG108's shareholding in the Company was reduced by the same proportion. Therefore, as of that date, SIG108 has no interest in the Company.

On March 14, 2016, our board of directors approved a corporate restructuring to simplify our organizational structure. In the previous corporate structure, GVT Participações S.A. ("GVTPart") was 100% owned by Telefônica Brasil. On the date of the merger, GVT was divided and its net assets were transferred in part to GVTPart and partly to POP. GVT's share of equity related to assets, rights and obligations related to telecommunications activities was transferred to GVTPart and other installments, related to assets, rights and obligations related to other non-telecommunications activities, were transferred to POP. GVTPart was later merged into Telefônica Brasil:

**The corporate restructuring did not result in an increase in capital or a change in the company's shareholders' participation and was ratified by an extraordinary general meeting on April 1, 2016.**

#### Acquisition of Telefônica Transporte e Logística Ltda. by TData
**On October 28, 2015, TData, as a buyer, and Telefónica Gestión de Servicios Compartidos España S.A., as a seller, signed a Share Purchase agreement that resulted in the acquisition of Telefónica Transporte e Logística Ltda., a Brazilian-based company that provides logistics services.**

Terra is a provider of digital services (own and third-party services of value added ("VAS") and carrier billing, as well as mobile channels for sales and relationships) and advertising. The goal of Transaction Terra Networks was to expand and integrate our digital services offering in order to provide additional value to our customer base and TData's, as well as to provide TData's service offering to Earth's customer base and subscribers. In addition, Transaction Terra Networks aimed to expand TData's advertising business as a result of Terra's national operations and expertise.

#### Restructuring Involving TData
On October 30, 2018, our board of directors approved the terms and conditions of the merger in the Company of its wholly-owned subsidiary TData, as well as the proposal to convene the Company's extraordinary general meeting for November 30, 2018, to resolve the merger. The merger aimed to standardize the provision of services, as well as simplify the company's organizational and corporate structure, being approved by the Company's Extraordinary Shareholders' Meeting on November 30, 2018, not resulting in an increase in capital or change in the Company's shareholders' equity.

#### Launch of Vivo Money Credit Rights Investment Fund (FIDC)
**In August 2020, in relation to the launch of our Vivo Money service, we structured the Money Credit Rights Live Investment Fund, which was created in the form of a closed company for an indefinite period.

#### Restructuring involving the sale of shares of Telefônica Cibersegurança e Tecnologia do Brasil Ltda. to Telefónica Cybersecurity Tech, S.L.
On November 1, 2020, our board of directors approved the execution of a quotas purchase and sale agreement, or the CyberCo Transaction, pursuant to which we sold a 100% equity interest in our subsidiary Telefônica Cibersegurança e Tecnologia do Brasil Ltda., or CyberCo Brasil, to Telefónica Cybersecurity Tech, S.L., or TTech, an indirect subsidiary of Telefónica, for the total amount of R$116.4 million, supported by an appraisal report commissioned by us.

***Investment by Telefónica Infra, S.L.U. and Caisse de Dépôt et Placement du Québec in FiBrasil Infraestrutura e Fibra Ótica S.A.***

On July 2, 2021, we executed certain agreements, or the FiBrasil Transaction, with Caisse de Dépôt et Placement du Québec, or CDPQ, a global investment group, and Telefónica Infra, S.L.U., or TEF Infra, a wholly-owned Spanish subsidiary of Telefónica, for the construction, development and operation of a neutral and independent optical fiber wholesale network in the Brazilian market, through FiBrasil Infraestrutura e Fibra Ótica S.A., or FiBrasil. The operation represents a total investment by CDPQ of up to R$1.8 billion (including payments to us and contributions to FiBrasil) in exchange for a 50% equity interest in FiBrasil's share capital. TEF Infra acquired a 25% equity interest for the same price, while we hold the remaining 25% interest. CDPQ has committed to make additional contributions of approximately R$750 million, of which R$205 million were paid on closing of the FiBrasil Transaction. These contributions, as well as debt that has been raised (such as FiBrasil's R$550 million debentures issuance on September 25, 2021) or that may potentially be raised by FiBrasil, are expected to finance the totality of its business plan.

FiBrasil is the leading company in the fiber wholesale market in Brazil. It began its operations with approximately 1.6 million FTTH homes passed, and a plan to reach around 5.5 million homes in four years, focusing on mid-sized cities outside the State of São Paulo. As FiBrasil's anchor client, we will accelerate its growth strategy in the fiber market by expanding its coverage from the current 16.3 million FTTH homes passed to 24 million homes with this technology by the end of 2024, enhancing the cross-selling of services to its customers, maximizing the return on invested capital. In 2021, the FiBrasil Transaction resulted in a positive impact in our cash flow, before taxes, of R$225 million.

Both the share purchase agreement and the shareholders' agreement have terms and conditions that are common to this type of transaction.

As a preliminary step in the implementation of the TC&T Transaction, certain assets, contracts and employees have been transferred from us and TIS to CloudCo Brasil, all strictly related to cloud computing activities. The TC&T Transaction will enable us, in partnership with TC&CT, to develop a Brazilian company dedicated to cloud computing solutions and services for the business-to-business segment, or B2B segment, which would improve our market position and product offerings and enable us to capture significant growth opportunities in this sector. Additionally, the TC&T Transaction also ensures that we continue to manage relationships with end customers, as we have also entered into an agreement whereby we will act as CloudCo Brasil's exclusive sales channel.

***Acquisition of UPI Mobile Assets of the Oi Group***

On April 20, 2022, the closing of the transaction related to the Purchase Agreement for Acquisition of UPI Mobile Assets of Oi Group took place, and we acquired, on such date, all the shares of Garliava RJ Infraestrutura e Redes de Telecomunicações S.A. ("Garliava"), a special purpose company, to which the mobile assets of Oi Group assigned to us had been contributed, in accordance with the segregation plan stated in the Oi Agreement.

Thus we acquired Garliava's shares for an approximate amount of R$5,373 million, having paid, on such day, the amount of R$4,885 million. The remaining amount, equivalent to 10% of the payment made on that date, was withheld and its release is currently subject to certain ongoing discussions regarding price adjustments, as provided for in the Oi Agreement.

The mobile assets of Oi Group finally assigned to us were the following:

● *Infrastructure:* agreements for the use of approximately 2,700 mobile access sites, or approximately 19% of the UPI Mobile Assets' total sites.

All commitments assumed were duly submitted to ANATEL and CADE during 2022.

#### Recent Developments

#### COVID-19 Pandemic
The COVID-19 pandemic has created significant volatility, uncertainty, and economic disruption. We continue to closely monitor the evolution of the COVID-19 pandemic in Brazil and globally, in order to take preventive measures to minimize the spread of the virus, ensure the continuity of operations and safeguard the health and safety of our personnel. Based on the information available as of the date of this annual report, we present below a summary of the main effects of the COVID-19 pandemic on our business and results of operations:

● Our stores faced little to no restrictions in their operations in 2022, as the number of COVID-19 cases fell and vaccination rates rose in Brazil, removing limitations we had during 2020 and 2021;

● The impact on revenues was also of little relevance, not only because of the macroeconomic recovery, but also due to the increased perceived relevance of connectivity, which became of absolute essentiality, yielding increased data consumption and higher sensitivity to network quality. Accordingly, our mobile accesses increased by 14.1 million, also helped by the acquisition of Oi Móvel's assets, reaching an all-time high of 98.0 million, while our FTTH additions in the period reached 874 thousand, taking our FTTH subscriber base to 5.5 million for the year ended December 31, 2022;

● Costs related to sales, such as sales commissioning and advertising, continue to be positively impacted by the increased digitalization initiatives and automation of customer care; and

● Due to the aforementioned increased demand for telecommunication services, efficient financial management and despite the macroeconomic downturn, our level of bad debts fell by 8.4%.

&nbsp;&nbsp;&nbsp;&nbsp;B. **Business Overview** 

We are the leading mobile telecommunications company in Brazil (with a 38.9% market share as of December 31, 2022, based on accesses), with a particularly strong position in postpaid mobile services (41.9% market share as of December 31, 2022, based on accesses). As of December 31, 2022, we reached 17.7% of total market share in FTTH (fiber-to-the-home) accesses in Brazil.

Our Vivo brand, under which we market our mobile services, is among the most recognized brands in Brazil. The quality of our services and the strength of our brand recognition enable us to, on average, achieve higher prices relative to our competition and, as a result, generally earn higher margins. As of December 31, 2022, our average revenue per mobile user, or ARPU, of R$26.3 represented a premium relative to the market average. We offer our clients a complete portfolio of products, including mobile and fixed-line voice, mobile data, fixed broadband, ultra-fast broadband, or UBB (based on our Fiber to the Home, or FTTH and Fiber to the Curb, or FTTC infrastructure), Pay TV, information technology and digital services (such as entertainment, cloud, security and financial services). We also have one of the most extensive distribution networks in the sector, where our clients can obtain certain services, such as purchasing credit for prepaid phones.

**We seek to continue to increase our operating margins by focusing on developing and growing our product offerings so that they comprise an integrated portfolio of higher-margin services.**

We were the

[**Table of Contents**](#TOC)

first telecommunications company to be granted the authorization to develop local, intraregional, interregional and international services throughout Brazil, including outside our concession area.

#### Mobile services
According to data regarding market share published by ANATEL in December 2022, we are the leading provider of mobile telecommunications services in Brazil in terms of accesses.

Our mobile portfolio includes voice and broadband internet access through 3G, 4G, 4.5G and 5G (the latter of which is in the process of implementation), as well as value-added services (such as *Atma, VivaE, Vida V, Vivo HomeFix, Vivo BTFIT*, Go Read, Ubook, Hube Jornais, NBA and NFL), prepaid plans with data sharing features, family plans, voice mail and voice mail speech-to-text translation, caller identification, voice minutes in unlimited bundles to mobile and fixed phones, ringtones, and innovative services such as multi-media backup, cloud-based services to save texts, entertainment and music apps, advertising platforms, among others.

We also offer wireless roaming services through agreements with local mobile service providers throughout Brazil and other countries, allowing our subscribers to make and receive calls while outside of our concession areas. We provide reciprocal roaming rights to the customers of the mobile service providers with which we have such agreements.

#### Data services
We provide fixed broadband through fiber (FTTH – fiber-to-the-home and FTTC – fiber-to-the-curb) and xDSL technologies, with speeds ranging from 1 Mbps to 1 Gbps.

Through the GVT acquisition in 2015, we were able to further expand our data services by providing high-speed broadband to high-income customers across our target markets. GVT provided services that were complementary to our own, with limited overlap with the services we already provided. Such complementary services included fiber broadband to locations in the state of São Paulo (outside of the city of São Paulo, where we already have a large presence) and nationwide.

In 2022, we covered 100% of the municipalities in our concession area in the state of São Paulo and hundreds of others throughout Brazil, reaching more than 6.5 million fixed broadband customers in total, and we expanded our national fiber network to reach approximately 28.6 million homes, of which 23.3 million alone consisted of FTTH technology.

In mobile broadband, we use a variety of technologies to provide wireless internet services to our customers. Our 3G network is currently available nationwide. In addition, we offer HSPA+ technology, which is commercially known as 3G Plus. This technology allows customers with compatible terminals (including handsets) to reach up to three times the speed of traditional 3G. As of December 31, 2022, we covered 4,895 municipalities with our 3G network, reaching 97.1% of Brazil's population. We also offer 4G LTE technology, which, by the end of 2022, was available in 4,634 municipalities, reaching 95.5% of Brazil's population, 4.5G LTE through carrier aggregation in 3,342 municipalities, reaching 87.2% of the Brazilian population, and also 5G technology, present in 27 municipalities, equivalent of 23.9% of the Brazilian population.

In November 2021, ANATEL held the largest spectrum auction in its history, which included 4G and, for the first time, 5G blocks, with 700 MHz, 2.3 GHz, 3.5 GHz and 26 GHz lots. On that occasion, we acquired 3.5 GHz and 26 GHz national licenses (100 MHz and 600 MHz bandwidths, respectively). We also won regional 2.3 GHz licenses, with 50 MHz bandwidth in the southeast region of Brazil (except São Paulo state and PGO Sector 3) and 40 MHz bandwidth in São Paulo state and in the north and mid-west regions of Brazil (except PGO Sectors 22 and 25). These acquired licenses, which we purchased for a total of R$4.45 billion, of which R$0.93 billion is related to licenses and the remaining amount related to the obligations ANATEL set forth. The licenses ensure we have the required spectrum to provide 5G services, and are valid for 20 years (renewable under the then-existing legal conditions at the expiration of this term).

#### Pay TV services
**We began offering subscription-based television services, or Pay TV services, via DTH ("direct to home," a special type of service that uses satellites for the direct distribution of television and audio signals to subscribers) on August 12, 2007. By the end of 2022, we discontinued the DTH operations, disconnecting all customers. From 2023 onwards, we will only provide Pay TV services** 

[**Table of Contents**](#TOC)

**by means of IPTV (a type of service that offers video broadcast through the IPs) technologies. As of December 31, 2022, we had 1.0 million Pay TV customers, including 0.9 million IPTV customers.**

#### Network services
Our network management technology ensures comprehensive management and supervision of all our network processes and network performance for our clients. Our network management center monitors the critical network operational parameters of the countrywide transmission backbone, IP networks, mobile and fixed packet/circuit core networks, value-added services/multimedia platform and global services, radio access network, infrastructure and online services performance, as well fixed access network across the country, broadband networks, network interconnection, portability and IPTV/DTH. The center is able to identify abnormalities in both our network (fixed and mobile) and in third-party networks including networks of other operators and other corporate clients, using failure, signaling, quality and service monitoring systems. Our network management center is integrated with maintenance and operations teams that maintain and operate mobile and fixed network elements, as well as infrastructure and transmission, in addition to the radio network elements and computing bases, service platforms and communications backbones.

Our network provides for continuity of service to our customers in the event of network interruptions. We have developed contingency plans for potential catastrophes in our switchboard centers, power supply interruptions and security breaches.

We continuously aim to consolidate our network and increase its offerings, to deliver the best possible service to our customers and to meet their expectations. Currently, our monitoring process has been supported by automated systems (Robotic Process Automation, or RPA) which increases the effectiveness of incident correlation, recovery and management. This advancement gives our team more efficiency and speed in detecting and solving problems in our networks. Some of the improvements we have made in recent years include advancements in the migration of time-division multiplex switches to next-generation network switches, which offer new digital services to our clients and reduce our maintenance costs, including improvements in levels of security, power supply, battery and air conditioning infrastructure. The most significant implementation of fixed network technology has been a project to exchange optical cabinets, used for offering voice and data services for Multi-Service Access Nodes, which allows us to offer broadband service to many clients who did not previously have this service.

**In addition, we are widely applying advanced virtualization solutions (net functions virtualization, or NFV) to support the next generation of mobile networks, known as fifth-generation or 5G, which is operating and prepared to address future market and customer expectations by providing massive device connectivity (through IoT technology), very low latency, and higher data transfer rates.**

#### Network and facilities
We provide services referred to as industrial exploration of dedicated line (*Exploração Industrial de Linha Dedicada*, or EILD) pursuant to our concession agreement and our authorization agreements. The EILD consists of the rental of dedicated circuits and clear channel protocols for the provision of services to third parties.

In addition, we are able to offer a complete portfolio of wholesale products, including L2L, IP, Ethernet and MPLS. All of these products are used to meet the demands of other network operators and regional internet providers. The circuits are requested with different service level agreements, and we are required to provide the facilities with contingency routes, sites and equipment to improve the service against points of failure.

Our network consists of an access layer that connects our clients through our copper or optical networks, which are connected to voice and data centers. These centers are interconnected locally or remotely through transmission equipment connected predominantly with fiber optics and occasionally through a microwave network, which together form a network layer that enables connectivity between the various platforms as well as interconnection with other carriers. Our network strategy is based on the expansion of the fiber optic access network to allow greater coverage and broadband services for our customers, as well as to develop an integrated multiservice network and multimedia applications. As a telecommunication service provider, we do not manufacture equipment for the construction of our networks and facilities. We buy the equipment from qualified suppliers in Brazil and abroad and through such equipment, we implement our networks and facilities through which we supply our services.

[**Table of Contents**](#TOC)

#### Wholesale services (including interconnection)
We have continuously adapted and expanded our network topology aiming to develop new business opportunities throughout Brazil by offering services to other telecommunications companies. The result has been a significant increase in the number of providers that use our wholesale services.

As part of our wholesale services, we provide interconnection services to users of other network providers. We earn revenue from any call that originates from another mobile or fixed-line service provider network connecting to one of our customers. We charge the service provider from whose network the call originates an interconnection fee for every minute that our network is used in connection with the call. See "—Operating Agreements—Interconnection Agreements."

At the end of 2022, we had 693 local and long-distance interconnection agreements with Telefonica Brasil (fixed and mobile operation) and 265 agreements for the provision of local and long-distance traffic.

An interconnection is a link between compatible telecommunications networks that enables a fixed or mobile service user of one network can adequately communicate with the users of a network from another provider.

All providers of telecommunication services (fixed or mobile) are required to provide interconnection upon request to any other telecommunication collective service provider. The conditions for interconnection agreements may be freely negotiated among the parties. The agreements are required to be formalized by contract, whose effectiveness depends on ANATEL's approval. If any given agreement is contrary to the principles of free competition or conflicts with other regulations, ANATEL may reject it. If the parties cannot reach an agreement on the terms of interconnection, including the interconnection fee, ANATEL may determine those terms and conditions by arbitration.

#### Digital services (including value-added services)
*Overview*

In 2022, we reinforced our purpose of "digitalize to bring closer" (*digitalizar para aproximar*).

We continued to improve the experience of our products and digital services, with even more precise offers and exclusive conditions for our clients.

According to Omdia, we are the third Telecom company in the world in terms of the number of relevant partnerships in digital services. This shows our commitment to improving our value proposition, adding high quality services to the portfolio and creative collaborations with companies that are a reference in the digital and entertainment world.

The value proposition of the traditional plans with digital services, such as Netflix, Amazon Prime, Globoplay, and several others in Vivo Selfie Plans, are great strengths. Selfie Plans include a subscription to one of the services, with an additional data package and many other benefits of the postpaid plans.

We have also implemented similar bundles in Fixed Broadband, delivering to the public the entertainment value proposition associated with our fast connection in Fiber (FTTH). In this model, we have launched options combining FTTH with Netflix, Disney, Amazon Prime and Globoplay.

To the entry-level Post Paid plans, we added two new products in 2022: Controle + Tidal, an opportunity to increase the perception of the value proposition with a relevant player in the music spectrum, and Controle + Dotz, a plan that allows clients to accumulate points and exchange for products, trips, and other benefits in a high-rated loyalty program in Brazil.

In 2022, several stand-alone offers were also launched in our portfolio, besides new strategic players, giving our customers the choice to subscribe to these services by paying directly with Vivo's bill:

● Globoplay + Canais Ao Vivo: Gives access to the best premium Pay TV channels, like Multishow, GNT, SporTV, GloboNews, and many others, besides movies, series, soap operas, and other on-demand content.

[**Table of Contents**](#TOC)

● Discovery+: One of the most important networks on the planet, offering more than 30 thousand episodes of new and very well-known shows.

● Vivo Play App: A new option for customers to access a vast entertainment content offer, live and on-demand, anytime, anywhere and on any device. The product works through an app, with traditional Pay TV channels and access to thousands of on-demand content, without the requirement of a Set-top box to be fully functional. There are two packages, "Initial," with 42 live channels, and "Extended," with 87 channels.

During 2022, we continued to develop and increase communication with our clients, with a distinguished strategy for each one of our services, allied with specific promotions (price and period) that allows growth in sales throughout the year. The standalone products reached a +42% YoY customer base in 2022.

Also, the Vivo App has one of the most important roles in the expansion and visibility of Digital Services. Vivo App is responsible for overall 62% of all the sales of the standalone offers of the most relevant players, like Amazon Prime, Disney+, Globoplay, Spotify, HBO Max, and others.

With Vivo App, digital services gained more exposition with several new spaces to communicate the offers, with banners, recommended apps positions and premium positions to communicate special conditions.

Besides all launches and achievements, we also continued to increase the visibility and communication of exclusive promotional subscriptions through our loyalty program, Vivo Valoriza. In this program, eligible Vivo customers can redeem special prices and conditions from several digital services.

*Financial services*

Financial services are highly strategic for us, as it reinforces our position as a digital service hub, offering our customers far more than telecommunications services. Therefore, in October 2020, we launched our personal credit service for our customers, called Vivo Money. After 2 years of tests, 2022 was the year for consolidating Vivo Money as an important line of business. Currently, it grants credit to customers ranging from R$500 to R$50,000, offering competitive rates, starting at 0.99% per month up to 36 installments – always taking into consideration the individual customer's credit behavior. Vivo Money also has a device financing service, on a strategy to create synergy with our core businesses.

Our financial service portfolio goes beyond credit and consolidates solutions for our customers. Vivo Pay, our digital bank account, is another important landmark for our financial services strategy.

Launched in 2021, Vivo Pay is the digital account free of charges and available to all our customers. It supports financial inclusion in Brazil by offering, among other functionalities, a prepaid card free of charges for online shopping. Also, users can pay bills and transfer money to any bank account in Brazil through PIX, the Brazilian instant payment system, enabling instantaneous and cost-free money transfers and payments at any time or day of the week.

In Vivo Pay, customers can also ask for Vivo Itaú Card – the credit card that Vivo has in partnership with Banco Itaú. In this new version, launched in 2022, it brings benefits such as 10% cashback for all Vivo purchases, in addition to offering up to 24 installments without interest in Vivo's stores.

Another feature included in Vivo Pay, is Vivo Seguro Celular – the mobile insurance product partnered with Zurich – is offered to every customer to protect their Smartphones, with a digital and seamless journey. Also with Zurich, new insurance plans were launched for protecting electronic devices like laptops, smartwatches and tablets – confirming the well-established partnership and the high potential for improving services to all our customers.

*Corporate innovation*

In 2022, we continue to grow in the digitalization process and build new technological products and services. As the largest company in the sector in terms of client base, the innovation process and creating value through our key assets becomes essential to stay in the top and seek new avenues of growth in an already consolidated and traditional market such as telecommunication.

[**Table of Contents**](#TOC)

Based on our digital product knowledge and our main assets such as customer base, brand, billing capabilities, we strategically selected some key segments of the Brazilian market to invest and create new businesses. As a robust company, we have a competitive edge to reach specific audiences. More than that, having millions of customers, it is important to understand their needs and offer new products that are suitable and personalized for the clients and, at the same time, can contribute to complementing the telecom offers. More than launching, several products were restructured, and others are in a growth phase.

● In the health space, we re-launched Vida V, a complete ecosystem spanning thousands of doctors, clinics and labs at very aggressive price ranges, creating an affordable alternative for health insurance. The business has presented important growth rates in the first 5 months and already has thousands of subscribers.

● In Education, we created a joint-venture with one of the largest education company in Brazil: Ânima Educacional and launched VivaE. It is a 100% online course platform that prepares people for the job market and helps them to improve their lives. The APP and the contents were developed from scratch, in a personalized and exclusive way. The APP is available throughout Brazil and in 2023 the goal is to scale and get more clients.

● Smart Home: New positioning of the value proposition of services based on relevant pillars of the customer journey (Smart Home consultancy, installation, device configuration and specialized support) complementing "Tem Tudo Na Vivo" positioning in the sale of smart devices. Service launch with an on-site technician for installation, configuration and creation of automation in the city of São Paulo capital and metropolitan region. Actions on the highly-rated TV Show "Pantanal" and on Vivo channels boosted the growth of Vivo Guru with remote support service, ending the year at approximately 38 thousand customers.

● In the mindfulness vertical the key decision was to rebrand Vivo's product to "Atma" with the objective of positioning the brand more independently and reducing the barrier for customers from other Telcos. Aligned with the new brand, we launched a new app, a better experience, and a different strategic position. This resulted in an average 15 p.p. increase in monthly active users (MAU). Also, during 2022 there were important strategic actions, such as adding new features and music, reinforcing our value proposition, and contractual optimizations with the main stakeholders which helped improve our profitability. Atma had its first big media appearance in the TV Show "Pantanal", with product placement actions, TV and Spotify's spots, digital media and communication with our clients. All these actions allowed Atma to grow significantly in 2022, closing the year with over 1.5 million downloads, more than 300 thousand active users and excellent evaluations on the app stores (4.5 in Apple Store and 4.2 in Google Play).

In addition to internal development and partnerships, we continue to invest heavily in our innovation processes, culture and search for good business with startups that can add value to our ecosystem.

In 2019, we launched our corporate open innovation program, Vivo Discover, and continues to stimulate innovation through a mindset change of the employees and new business development. The main program that increases our innovation culture, the Vivo Shaper, started in 2022 the fourth class with 30 executives end consultants that go through a six-month course on key methodologies and topics about the innovation process, startups culture, and how to develop a new business with the startups for revenue generation.

In recognition of the ecosystem and the market, we have received several awards:

● Valor Inovação Brasil: TOP1 Telecom

● 100 Open Corps: TOP1 Telecom and 6th place in the general ranking

● Época 360: TOP1 innovative telecom of Brazil

● Empresas Mais Estado de SP: TOP1 Telecom and 14th place in the general ranking

● Telesíntese: TOP3 communication and infrastructure providers – Vivo Ventures

● ABVCAP: TOP 2 CVC – Vivo Ventures

● Grow+ Innovation Awards: TOP1 Open Innovation Corp – BNDES Garagem

[**Table of Contents**](#TOC)

● The Bakery: TOP20 best companies for the Brazilian startup ecosystem

At Wayra, our innovation hub and corporate venture capital, we had a year of achievements. We had the entry of Gabriela Toribio, in the position of Managing Director of Wayra Brasil and Vivo Ventures, to lead the team aimed at bringing startups and Vivo closer together to generate business opportunities together, to continue boosting the entrepreneurial ecosystem with contracts and financial contributions.

In April 2022, we launched a new CVC (Corporate Venture Capital) fund, Vivo Ventures, with the objective to invest in startups in verticals such as Smart Home, Marketplace, Health, Finance and Education, which are key to positioning our company as a digital hub. The fund of R$320 million will focus on A and B round startups, with a 5-year investment window. Both vehicles (early-stage and growth) are managed by Wayra and will work to make the most of opportunities for Vivo and the Telefónica group.

#### Corporate services
We offer our corporate clients comprehensive telecommunications solutions and IT support designed to address specific needs and requirements of companies operating in all types of industries (retail, manufacturing, services, financial institutions, government, etc.).

Our clients are assisted by our highly qualified professionals who are capable of meeting the specific needs of each company with voice, data, broadband and computer services solutions, including hardware and software (for example, anti-virus software). We work to consistently achieve greater quality and efficiency in our services and increase our level of competitiveness in the market.

#### Sale of devices and accessories
We sell 5G NR, LTE and WCDMA devices such as smartphones, broadband USB modems and devices that are certified to be compatible with our network and service, including eSIM devices. We also sell a high range of connected and non-connected gadgets offering our customers quality and technological products.

We have special offers on smartphones, USB modems and other data devices for customers of bundled packages.

Our current device suppliers are Samsung, Apple, Motorola, Usina de Vendas (Oppo), Positivo (Infinix), Multi (Nokia and Multi), ZTE and Flex (WNC and Blucastle) and our gadgets suppliers are Samsung, Apple, Harman (JBL), Lenovo, Allied (Google, Logitech Xbox and TPLink), Timbro (Amazon), Customic, Alfacomex (Geonav), Positivo, Intelbras, Multi (DJI and Multi), DPC (Motorola), Tellescom (Askey) and Coravin.

Devices and gadgets sales continued to grow in 2022, in line with our strategy to gain market share in this important market, through portfolio and distribution expansion, and also strong communication and brand awareness initiatives built on our "You can find everything at Vivo" campaign (in Portuguese, Tem Tudo na Vivo), a call to action emphasizing that Vivo can provide everything customers need, and also through our sales channels, which focused on attracting high-value customers to our physical and online stores. By the end of the year, we launched our own accessories brand, Ovvi, focused on design and quality, trying to add even more market value.

#### Rates, Taxes and Billing

#### Rates
We generate revenue from (i) activation and monthly subscription charges, (ii) usage charges, which include measured service charges, (iii) interconnection fees that we charge to other telecommunications service providers, and (iv) other additional services. Rates for all telecommunications services are subject to extensive regulation by ANATEL. We set forth below the different methods used for calculating our rates.

[**Table of Contents**](#TOC)

*Local rates*

Our concession agreement sets forth three mandatory plans for local fixed-line service and allows us to design alternative pricing plans. Customers have a choice between the three plans that we are required to offer, or any other alternative plan that we may choose to offer. ANATEL must be notified of the offering and implementation of any alternative plans. The three mandatory plans are:

● Local Basic Plan *(Plano Básico Local)*: for clients that mostly make short-duration calls (up to three minutes) during regular hours;

● Mandatory Alternative Service Plan (*Plano Alternativo de Serviços de Oferta Obrigatória*): for clients that mostly make long-duration calls (over three minutes) during regular hours and/or that use dial-up service to access the internet; and

● Special Class Individual Access (*Acesso Individual Classe Especial*): a plan created specifically for families enrolled in governmental assistance programs.

The following table outlines the basic billing requirements and gross rates for the Local Basic Plan and the Mandatory Alternative Service Plan as of the date of this annual report:

---

| | | |
|:---|:---|:---|
| <br>**Characteristics of Plan** | <br>**Local Basic Plan** | **Mandatory**<br>**Alternative**<br>**Service Plan** |
| Monthly Basic Assignment |  |  |
| &nbsp;&nbsp;Residential Allowance (minutes included in the residential assignment) | 200 minutes | 400 minutes |
| &nbsp;&nbsp;Commercial Assignment Allowance (minutes included in the commercial assignment) | 150 minutes | 360 minutes |
| Local Call Charges |  |  |
| &nbsp;&nbsp;*Regular Hours* |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Completing the call (minutes deducted from the allotment) |  | 4 minutes |
| &nbsp;&nbsp;&nbsp;&nbsp;Completing the call (after the Sector 31 terms of allotment) |  | R$0.24023 |
| &nbsp;&nbsp;&nbsp;&nbsp;Local minutes (charges in excess of the Sector 31 allotment) | R$0.11804 | R$0.04786 |
| &nbsp;&nbsp;&nbsp;&nbsp;Minimum call length billing | 3 seconds | 3 seconds |
| *Reduced Hours* |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Charge per answered call (minutes deducted from allotment) | 2 minutes | 2 minutes |
| &nbsp;&nbsp;&nbsp;&nbsp;Charge per answered call (after the allotted Sector 31 duration) | R$0.24023 | R$0.24023 |

---

As of the date of this annual report, the subscription to the Special Class Individual Access plan costs R$11.34 per month for 90 minutes of local, fixed-line calls per month. Any additional fixed-line or mobile calls may be made only if the customer purchases prepaid credits. The prices of mobile and long-distance calls are determined pursuant to a standard plan.

Our concession agreement also sets forth criteria for annual fee adjustments for all of our plans for local fixed-line service. We derive a substantial portion of our revenues from services subject to these price adjustments. Prices are adjusted by an annual price readjustment index applied by ANATEL to our local and long-distance fees that reflects the inflation index for the period and a productivity factor, which is calculated based on a compensation index set by ANATEL to share earnings from fixed-line services with their users. Currently, the inflation index used by ANATEL is the IST, which reflects variations in the costs and expenses of telecom companies. ANATEL has consistently complied with the fee range set by our concession agreements.

*Long-distance rates*

Rates for domestic, long-distance calls are based on the time of day, the day of the week, and the duration and distance of the call, and may also vary depending on whether special services, including operator assistance, are used. We have several options for domestic, long-distance calling plans for consumers using our carrier dial code (15). Customers of any local or long-distance operator may use dial code 15 when dialing long-distance to benefit from our rates. In March 2020, ANATEL approved Resolution No. 724, which established a standard for the implementation and monitoring of tariff freedom in the STFC, for use by the general public in the national, long-distance mode. Since then, we have been free to set domestic long-distance fees at market rates.

We also offer international long-distance rates, which are also available to all users using dial code 15. International, long-distance calling charges are based on the time of day, the day of the week, the duration and the destination of the call, and may also

[**Table of Contents**](#TOC)

vary depending on whether special services are used, including operator assistance. Our rates for international services are not subject to regulation and are not required to follow the annual rate adjustments described above for other services. We are free to negotiate our fees for international calls based on the international telecommunications market, in which our main competitor is Claro (through its Embratel business).

With respect to long-distance calls, we have developed alternative rate plans for residential and corporate customers.

*Mobile services rates*

Rates for our Local Basic Plan and certain roaming charges incurred in connection with alternative service plans are subject to annual adjustments pursuant to our authorizations. Current rates, which are revised annually, can be readjusted for the following year at most by the rate of inflation as measured by the IGP-DI index. The maximum rate applies to all service plans, but mobile operators are allowed to freely set the maximum rates for alternative service plans (other than with respect to certain roaming charges).

The initial price cap we agreed upon with ANATEL in our authorizations was based on previously existing or bidding prices, and has been adjusted annually based on a formula contained in our authorizations. As of the date of this annual report, the most recent adjustment was approved in May 2022, which set fees at R$0.22222 for regular hours and R$0.15555 for reduced hours.

#### Interconnection fees
We are paid interconnection fees by any fixed-line or mobile service provider that either originates or terminates a call within our network. We also pay interconnection fees to other service providers when we use their network to place or receive a call. The interconnection fee is a flat fee charged per minute of use that directly affects fixed-line mobile services rates. Since 2005, interconnection agreements are freely negotiated among the service providers, subject to a price cap and to compliance with the regulations established by ANATEL, which include not only the interconnection basic costs including commercial, technical and legal aspects, but also the traffic capacity and interconnection infrastructure that must be made available to requesting parties. If a service provider offers to any party an interconnection fee below the price cap, it must offer the same fee to any other requesting party on a non-discriminatory basis. If the parties cannot reach an agreement on the terms of interconnection, including the interconnection fee, ANATEL can establish the terms of the interconnection.

For additional information about interconnection fees, see "—Regulation of the Brazilian Telecommunications Industry—Interconnection fees."

#### Data services rates
We receive revenue from charges for data transmission, which includes our fixed broadband, dedicated analog and digital lines for privately leased circuits to corporations and other services. Data transmission rates are not regulated by ANATEL, except for EILD (wholesale links up to 34 Mbps) and High Capacity Data Transport (wholesale links above 34 Mbps). Multimedia services operators can freely set the rates for alternative service plans.

#### TV rates
Pay TV rates are not regulated. Service providers are allowed to freely set the rates for alternative service plans.

#### Taxes
The cost of telecommunication services to each customer includes a variety of taxes. The main tax is a state value-added tax, the Imposto sobre Circulação de Mercadorias e Serviços, or ICMS, which the Brazilian states impose at rates ranging from 4% to 22% on certain revenues from the sale of goods and services, including telecommunication services. Telecommunication services have recently been classified as essential by Supplementary Law No. 194/2022. As such, the ICMS rates on telecommunication services cannot exceed the general ICMS rates foreseen by each State's local regulations. Most States respect this new legislation and currently tax telecommunications services according to the general ICMS rate, but there are some specific States that do not respect the law. Other taxes include: (1) Federal Social Contributions (Contribuição para o Programa de Integração Social), or PIS, and Social Security Financing Contributions (Contribuição para o Financiamento da Seguridade Social), or COFINS; (2) FUST contributions; (3) FUNTTEL contributions; and (4) FISTEL contributions".

***Billing***

For postpaid customers, we send each contract customer a monthly bill covering all of the services provided during the previous monthly period. Pursuant to Brazilian law, telephone service providers are required to offer their customers the choice of at least six different monthly payment dates. For prepaid customers, billing is available online.

We have a billing and collection system with respect to local, national and international long-distance voice, subscriptions, broadband, data, IT services, outsourcing, television and third-party services. For invoice payments, we have agreements with various banks. These agreements include options for customers to select their preferred payment type: direct debit, PIX, payment to a bank, Internet and other collection agencies (including lottery-playing facilities, drugstores and supermarkets). We aim to avoid losses in the implementation of new processes and the roll-out of new products through the monitoring of billing, collection and recovery controls.

These practices are closely monitored by our revenue assurance team, which measures every risk of revenue loss detected along the billing and collection chain. These risks are managed to minimize revenue losses.

*Co-billing*

In accordance with Brazilian telecommunications regulations, we use a billing method called "co-billing" for both fixed and mobile services. This method allows billing from other phone service providers to be included within our own invoice. Our customers can receive and subsequently pay all of their bills (including the fees for the use of services of another telephone service provider) on our invoice. To allow for this method of billing, we provide billing and collection services to other phone service companies. We have co-billing agreements with national and international long-distance phone service providers. Similarly, we use the same method of co-billing to bill our services to customers of other fixed and mobile providers. This service is charged to the long-distance operator, by means of a call record described in the invoice.

*Value-added services*

Value-added services such as entertainment, information and online interactivity services are available to mobile prepaid as well as postpaid customers through agreements with content suppliers. These agreements are based on a revenue-sharing model.

*Third-party services*

We incorporate third-party services in our billing, collection and transfer process. These services are later passed on to the third-party contractor.

*Collection*

Our collection policies with respect to customers in default follow ANATEL regulations, as well as those of Serviços de Telecomunicações, or RACO, and the Foundation for Consumer Protection and Defense (*Fundação de Proteção e Defesa do Consumidor*), or PROCON. For mobile, fixed and Pay TV customers, as a general rule, if payment is more than 15 days overdue, service can be partially suspended by blocking out-going calls that generate costs to the customer. If payment is more than 30 days overdue after this partial suspension, the service can be fully suspended, disabling all services (outgoing and incoming calls), until payment is received. We offer an installment payment plan for clients with overdue balances. However, if accounts are not paid after 30 days following the total suspension, the contract can be canceled and reported to credit protection agencies.

The collection process for customers in default involves several steps, from an internal interactive voice response, SMS contact, email contact, followed by a late payment notice, and finally reporting customer information to an external credit bureau. Concurrently with our internal process, delinquent customers are also contacted by collection agencies. Customer risk profile, overdue debt and other quality issues are used to increase strategy efficiency and maximize debt recovery efforts. As of January 2018, bad debt provisions were adjusted due to changes brought by IFRS 9, including new criteria that follow an expected credit loss model, adopting a percentage of risk for each debt payment profile until the moment of effective loss (100%). The percentages were calculated according to the historical behavior of delinquency for each segment. In accordance with Brazilian regulations, bad debt write-offs are permitted for late payments of zero to R$5,000 if they are over 180 days late or R$5,001 to R$30,000 if they are over 365 days late. Late payments of over R$30,001 that are open for more than 365 days require a lawsuit to be initiated. This rule is applied for outstanding debt through October 8, 2014; after this period, the amount ranges for bad debt write-offs change as follows: zero to

[**Table of Contents**](#TOC)

R$15,000 if they are over 180 days late or R$15,001 to R$100,000 if they are over 365 days late. Lawsuits are required for debts over R$100,000 open for more than 365 days.

Provisions for doubtful accounts in the year ended December 31, 2022 were 1.9% of the total gross revenue.

**Our Markets of Operation**

Our concession agreement allows us to operate in the state of São Paulo, except for a small region that is still subject to an earlier concession. In addition, we offer fixed telephone, data and Pay TV services throughout Brazil pursuant to licenses and authorization. We operate mobile voice and broadband services throughout Brazil, under the mobile service (SMP) authorization.

#### Marketing and Sales
***Overview***

Our commercial distribution network (marketed under the Vivo brand), as of December 31, 2022, consisted of 246 own sales outlets throughout Brazil. In addition, we also have approximately 1,541 sales outlets run by authorized dealers (including exclusive dealers and retail channels), maintaining a solid capillarity strategy that contributed to our leadership position in the Brazilian telecommunications market.

As of December 31, 2022, we had approximately 322,326 points of sale where prepaid mobile service customers could purchase credits using the Distribution or Online channels. Prepaid phones can be credited remotely or by purchasing cards containing credits. Credits may also be purchased through credit and debit cards, call centers, Vivo PDV (M2M using a cell phone for transferring the credit), personal recharge (using the phone itself to recharge credits), as well as certain certified internet websites.

We bring our solutions to our customers through the following physical sales channels:

● **Vivo stores**: we continue to focus on the transformation of the traditional PoS (Point of Sale) into the PDX (Point of Experience), reaching eight iconic stores, two Stores-in-Store and 409 Plus Stores (a concept created to serve small and medium cities) as of December 31, 2022. By advancing on infrastructure, systems, customer service, micromanagement and capillarity improvements we believe we continue to provide an efficient, profitable and enchanting service. Even after the easing of the restrictions of the pandemic in 2022, we maintained our *Vivo* em Casa program, a tool where anyone can contact our store´s sales force, strengthening the digitalization of our stores.

● **Exclusive dealers**: this channel is made up of companies selected and certified to provide our complete product portfolio. These dealers make up an extensive distribution network across the country. Although the channel offers the entire product portfolio, its focus is on postpaid and Fiber products. We are also constantly updating and improving these stores to provide a better customer shopping experience, to ensure a consistent experience as in our flagship stores. In 2022, these resellers increased our store reach by more than 60 points of sale, which meant we were present in Brazil through 1,541 stores as of December 31, 2022.

● **Retail channel**: our retail channel sells postpaid and prepaid products and recharge services that are marketed by our partners' own sales teams. This channel maintains a strong partnership relationship with retailers through our sales incentive program (tying compensation to sale performance). In 2022, despite challenging market circumstances, we sustained a relevant volume in prepaid products, maintaining a substantial part of our capillarity through commercial and operational efficiency actions.

● **Distribution channel**: the broadest and most complex sales channel across our markets, this channel allows our prepaid customers to purchase data and voice credits. In order to be as close as possible to potential and existing customers, this channel comprises authorized agents, lottery stores, post offices, bank branches and small retailers, such as pharmacies, newspaper stands, bookstores, stationery shops, bakeries, gas stations, bars and restaurants. The channel is currently responsible for the majority of our prepaid sales (90%) and mobile recharges (65%). In 2022, we consolidated the prepaid market share leadership, which was achieved in the previous year with a 35% share, even after Oi´s mobile operation was split between Vivo, Claro and Tim. We grew our position in micromanagement including specific sales force payments with granularity at the POS level.

● **Door-to-door sales**: this channel continues to be strengthened with the growth of the Fiber network across the country, expanding the sales force, focusing on quality and now seeking to total our customers. It is our main fiber sales channel, representing almost 31% of all fiber sales in the B2C segment. The fiber market requires important local knowledge for greater sales penetration and that is why a hunter channel such as door-to-door sales is so important for this segment.

● **Outbound telesales**: characterized by the lack of geographical limitations, our outbound telesales channel can reach existing and potential customers across the whole country, offering our full product portfolio, from prepaid to postpaid products, as well as fixed voice, broadband and TV bundles, this channel has focused on increasing the client base by identifying new clients and offering suitable plans to our existing clients according to their consumption profile. This channel contributed to more than 200,000 unit sales per month.

#### Customer experience
In 2022, our purpose, "Digitalize to Bring Closer" was even stronger, with Vivo being more present, more potent and more plural. Our mission to digitalize transforms the world and its people through what we do best, connecting the people of our country. Digitalizing brings us closer and brings our clients closer to what matters the most to them, like digital health services, education, financial inclusion and entertainment. In this context, we have evolved to be even more present in our clients' lives.

We amplified our investments in connectivity and started the 5G technology revolution, we expanded even more the best fiber ultra-broadband connectivity and transformed our digital services' ecosystem, adding value to our clients' lives in the most diverse themes, such as health with Vida-V, financial services with the Vivo Money and Vivo Pay platforms, and entertainment with Vivo Play. In each contact point or need of our clients, we have guaranteed differentiated treatment and full support, from solving simpler themes through digital channels or with individualized and personalized customer service to solving complex issues.

In 2022, we also advanced in our methodology to perfect end-to-end experiences, differentiated, personalized and 100% thought out in our customers. To do so the business units have been structured into multidisciplinary Squads in agile models to understand the customers' needs and redefine simplified processes and custom-made to each profile. Our employees' work, together with our mission and the Vivo DNA, have assured us another outstanding year, recognized by the market and its consumers and yielding us over 20 national and international awards. We were recognized by specialized juries like the "DNA Solves" program, which was elected the best CX program in the category "Resolution Negotiations" worldwide in the global Customer Centricity World Series Awards. Our CX program was also recognized by the International CX Awards (ICXA) in the category "Best Culture Centricity Awards". We were also recognized by the public, with the "Folha Top of Mind" award, where we were recognized in 3 categories. And the Vivo DNA moves on stronger and rooted in the day-to-day of our employees through a collaborative culture and disseminated through programs like "Vivo DNA in action", where, in a super task force with our channels, we made two special editions opened to employees of all levels, executive or not, in regions of Brazil, in this program, where the employees could live the experience of being in the front lines, understanding and helping our clients on this end. In 2022 alone, there were 458 experiences and over 360 opportunities mapped and sent to business units to solve them. Our Ombudsman, which has the mission of winning back clients to a high level of satisfaction perception was also recognized by engagement awards.

In 2023, we will continue with our commitment to digitalize to bring closer and give enchanting experiences to the over 100 million accesses that chose us to provide connectivity and its digital services.

#### Technology
***Voice and data networks***

To offer a greater variety of integrated services, we incorporated several new technologies into our voice and data networks. In 2022, we have already consolidated our network virtualization program towards cloudification, having some data centers installed and operating. This allows us to fully offer services based on new technologies, such as 5G, which network functions are cloud-native. In 2022, we launched our first 5G standalone network offering 5G services for our clients.

For mobile voice services, we are moving forward to our digitalization process using VoLTE (Voice LTE) and investing more and more in such technology which has a lot of benefits when compared with voice in 3G/2G networks, such as voice in HD, fast call setup, multi-device services, etc. At the same time, we have already concluded our planning in order to offer VoNR (Voice over 5GSA) in the short-term.

For our fixed-line voice network, we offer VoFTTH (Voice over FTTH) services, SIP trunking and SIP interconnections, and have been increasing our network by launching in new cities while working on energy efficiency, site demobilization, voice digitization plans, and synergies between fixed-line and mobile networks, among other initiatives. To support VoIP growth, we are in the process of consolidating and growing our Unified IMS core, deploying some Session Border Controllers (SBC) on our access edge and peering edge. All these initiatives have made it possible savings in terms of energy consumption, labor and maintenance costs.

For our data core, we launched 5G Standalone and non-standalone architecture, continue to expand our mobile network geographically including 5G architecture, by expanding to new locations through additional points-of-presence and offering the best experience for our customers. Expanding Private Networks (LTE private) and data services IoT (LTE-M and Nb-IoT).

[**Table of Contents**](#TOC)

As more services migrate to IP, our IP backbone has become a strategic asset to support customer demands and increase revenues. The migration of sensitive and demanding services such as voice and television to IP has also increased the demand for higher quality broadband networks and is further bolstered by products such as cloud services and VoD. At the same time, the expansion of fiber optics to customer homes and the launch of our 5G services (carrier aggregation) increases bandwidth demands over networks. As a result, three main drivers have surfaced as critical to business: availability, performance and cost-effectiveness.

As more bandwidth is offered to customers, the need to bridge the gap between revenues and investment to cope with greater traffic becomes increasingly clear. The next step toward network simplification entails a deeper-level evolution, which was initiated in 2018 through the exchange of existing routers for new routers with a higher capacity, which enabled the consolidation of specialized routers, thereby reducing network layers, bringing services and content nearer to customers and, ultimately, transforming our backbone into a multiservice network. This new design acknowledges service evolution, as voice, messages and circuits become data packets, which reduces the need for growing capacity in multiple steps. We believe that in the coming years, layer simplification could allow us to bring content even further to the edge, improving costs and quality at the same time.

The foregoing actions are expected to optimize investment in an aggressive traffic increase context and lay the groundwork to deliver the next step in data services quality. Even though bandwidth has been the main technical advantage for several years, latency will take over as the main broadband selling point. To reduce network latency means delivering more responsive services and obtaining higher customer satisfaction. To achieve this result, we believe service should be decentralized and delivered closer to the edge of the network and to customers, which we have taken steps toward by expanding the use of caching solutions throughout the network, making content locally available to our customers, and reducing traffic costs while strongly improving the user experience without increasing access investments. We further optimized costs by sharing access networks with other Brazilian operators, in which IP backbones played a key role in connecting and transporting traffic among different operator's networks, reducing the need for mobile site expansion. Finally, as Internet address numbers in Brazil were exhausted in 2014 and our own resources are reaching critical levels, we have seen strong growth in the next version of the IP, or IPv6. We completed our IPv6 project in 2017, which is important to guarantee full connectivity to our clients, and support sales as we strive to keep expanding our customer base.

In projects related to the Local Area Network (LAN), we provide local connectivity to all platforms and servers that provide fixed or mobile telecommunications services in Telecom Data Centers. The local network works as access to all data network services connecting them to the IP backbone.

We continue to evolve the standard Ethernet local area network (LAN) framework to the TRILL protocol (RFC 6326). The use of this protocol makes it possible to increase the resilience of the environment, allowing for a considerable reduction in failures that may sometimes affect the service provided to the end customer. We are also implementing the concept of decentralization in Data Centers Telecom with Top of Rack (TOR) and End-of-Row (EOR) switches, allowing cost savings with structured cabling, reducing energy, space and cooling. To keep up with the growth of the network, in 2022 we increased the capacity of the sites, providing more port capacity in nine existing sites and implementing one new site.

We also continued to structure our CDN (Content Delivery Network) to improve the customer experience with our services, using the cache solution to reduce bandwidth consumption on the IP backbone, storing content locally from partners such as Google, Netflix, Akamai, Facebook, Globo and Tik Tok. This allows us to optimize network resources and improve service quality. For this network structure, we use stand-alone switches. In 2022, we increased capacity on nine existing sites due to increased data traffic.

In a structure of stand-alone switches similar to Caches, we implemented these switches to meet the demand for DNS servers in five sites.

***Network security***

In a digital world where telecommunication networks are becoming highly complex, the security of networks is an indispensable factor for the success of our customers and their business. The governance, risk management and compliance of our network is aligned with the group's business and is based on the CIS Controls framework which its structurization project has begun in 2022 towards its consolidation. We also continued to work in 2022 to detect threats and protect our network with new technologies such as: Security Analytics tool, Threat Intelligence and Firewall API tools, and increasing the number of team members with high-level skills against a variety of attacks, thus, reducing the risk of compromising our services.

[**Table of Contents**](#TOC)

In addition, to identify our vulnerabilities before an attacker, we perform cyber war games and tabletop simulations with our blue, purple and red teams to increase our cyber resilience and defensive skills. The game simulates a cyberattack, in which the red team is responsible for finding breaches in our systems; the blue team, for protecting them, while the purple team sets the rules and environmental conditions for the game.

***TV services***

We offer IPTV services through our FTTH network using an open platform, which was created to revolutionize the way we deliver IPTV services. Our open platform consists of Pay TV with video broadcasting offered through an IP. Our several global partners have developed modules in partnership with us to connect to our existing global video platform. Our local team customized the middleware for set-top-box to create a standardized version that brings better time-to-market for new developments and product releases, as well as future convergence between IPTV and OTT platforms. Several components were integrated to create a new ecosystem for IPTV, such as instant channel change, retransmission, and applications to provide a better user experience. Additional services such as pay-per-view and VoD are also available.

We deliver IPTV service to over 350 cities throughout Brazil as of December 31, 2022, and have sustained our growth from previous years by expanding the coverage of IPTV to new cities. We have created additional points-of-presence, increased the offering of local channels, and increased the quality of IPTV services delivered to remote locations. We have continued to expand the list of third-party integrations, offering our customers a smooth experience with streaming services such as Netflix, Amazon Prime Video, YouTube, YouTube Kids, Disney+ and Star+. In addition, in 2022 we launched an IPTV service based on OTT streaming, which includes up to 87 linear channels and access to our VoD catalog. Our IPTV interface was further redesigned to improve customer experience, as more channels are offered to customers and our CDN platform growth ensures our ability to offer additional VoD titles and OTT services. In our development plan, we expect to upgrade to the most advanced technology available, with a focus on integrating our services with the Internet and increasing the number of multimedia transmission services, with an emphasis on FTTH (GPON), NGN, DWDM, ROADM and IPTV.

In 2022, we terminated our DTH operation, shutting down the last transponders we had with satellite service providers. We have promoted an extensive communication plan throughout the year, offering customers the choice to migrate to our IPTV service or the OTT, depending on technical availability at each location. It was an important milestone in our evolution roadmap, allowing us to focus exclusively on the evolution of our IP-based TV portfolio.

#### 5G Acquisition
In December 2021, we acquired through auction, the following radio frequency sub-bands: 2.300 MHz to 2.390 MHz, 3.300 MHz to 3.700 MHz and 24.3 GHz to 27.5 GHz, which in turn will allow us to increase the capacity of our network in denser urban areas. With the acquisition of these frequencies, we guarantee 5G services provision, reducing significantly latency, enabling greater connectivity and higher download and upload speeds (10x faster than 4G network).

These 5G features have enabled the development and improvement of services such as: IoT, games, autonomous vehicles, virtual reality (VR), industry automation and agribusiness.

#### Acquisition of part of OI UPI Mobile assets
We acquired part of OI's UPI mobile assets, with approximately 12.5 million customers, 43MHz spectrum in 1.800 MHz, 2.100 MHz e 900 MHz frequencies, with Nationwide coverage, contracts for the use of 2,700 sites of mobile access, in Southeast (state of São Paulo), South (Paraná), Northeast (Pernambuco, Alagoas, Paraíba, Rio Grande do Norte, Ceará and Piauí) and North (Maranhão) regions, reinforcing the capacity and capillarity of our network.

***Mobile coverage***

In 2022, we continued to expand the capacity and coverage of our mobile networks to absorb continuous growth in voice and data traffic. We seek to set ourselves apart from our competitors by significantly growing our 4G and 5G coverage. As of December 31, 2022, our mobile network covered 5,034 municipalities in Brazil using different technologies such as 5G, LTE Advanced Pro, LTE, WCDMA and GSM/EDGE digital technologies, or 90.4% of the total municipalities in Brazil and 97.8% of the Brazilian population. We have the biggest LTE Advanced Pro (commercially known as 4.5G) coverage in Brazil (with 3,342 municipalities and 82%

[**Table of Contents**](#TOC)

population covered). In the same period, we have covered all 27 state capitals of Brazil with 5G SA and NSA; these cities together represent 24% of the Brazilian population.

Following the schedule of the GAISPI executive committee, from Jun 2022 to October 2022, Vivo activated the 5G network over the TDD 3500MHz spectrum in all 27 capitals of Brazil, where the clients with suitable terminals are already using this new mobile network, enjoying its benefits as Enhanced Mobile Broadband services.

Since 2015, we began to develop network sharing in 4G 2,600 MHz coverage with Oi and TIM. As of December 31, 2022, after the sale of Oi and project review, we covered 126 Brazilian municipalities using shared radio base stations and 223 municipalities using TIM´s network through RAN sharing. In 2017, we also began to develop 3G network sharing with Claro and, as of December 31, 2022, we covered 235 Brazilian cities using shared radio base stations and 139 cities using Claro's network through RAN Sharing. In 2018, we further began to develop 3G network sharing with TIM, and, as of December 31, 2022, we covered 17 Brazilian cities with shared radio base stations and 27 cities using TIM's network through RAN sharing. In 2019, we began to develop network sharing in 4G 700 MHz with TIM (as a proof of concept), and, as of December 31, 2022, we covered 10 Brazilian cities with shared radio base stations and 9 cities using TIM's infrastructure through RAN sharing. In 2019, we entered into a network sharing agreement with TIM for 2G, 3G and 4G technologies, which sought to expand our network and create synergies. As of December 31, 2022, we covered 363 Brazilian cities with shared 3G/4G radio base stations and 350 cities using TIM's infrastructure through RAN sharing. Also in 2022, 3G/4G Single Grid was deployed in the urban area of 50 cities by Vivo and 53 cities by TIM. RAN network sharing allows us to fulfill the ANATEL obligations that were imposed on us as part of our spectrum acquisitions, and reduces network deployment and maintenance costs to provide additional coverage at lower costs.

#### Fraud detection and prevention
During 2022, we continued our work in combating the two main types of fraud, as follows:

● *Subscription fraud*: is a type of fraud that occurs when the issuance of one or more accesses are granted without the consent of the real "holder" of identification documents with the main objective of evading payment. In 2022, we registered a reduction of 16% in losses related to subscriptions, from R$70.5 million in 2021 to R$59.2 million in 2022. The main initiatives for this reduction were the expansion of the security layers (Biometrics, Devices Behavioral Analysis, among others), as well as the constant improvement of rules and revision of detection and prevention procedures.

● *Identity Fraud*: also known as "social engineering," an identity fraud takes place through call centers, our own stores or our resellers, where a caller that has access to information belonging to our existing clients' contacts our call centers and makes unauthorized changes and activations. We had a reduction of 72% of cases in 2022, going from 2,268 cases in 2021 to 634 cases in 2022. Said reduction is related to many improvement processes in access management, CRMs and Biometrics in all service channels of the company. Restriction of access for the chip exchange in non-face-to-face channels (i.e., Call Centers) submitting the client to go through this process only in a presential channel, through biometric authentication of the client.

#### Operating Agreements

#### Interconnection agreements
The terms of our interconnection agreements include provisions with respect to the number of connection and signaling points. See "—Regulation of the Brazilian Telecommunications Industry—Interconnection Fees" and "Item 4. Information on the Company—B. Business Overview—Rates, Taxes and Billing—Interconnection fees." We believe that we have adequate interconnection agreements with fixed-line operators necessary to provide our services and that we have all the necessary interconnection agreements with long-distance carriers.

#### Roaming agreements
We provide international GSM roaming in over 200 destinations worldwide by means of over 500 roaming agreements with local service providers.

[**Table of Contents**](#TOC)

We have a roaming agreement with MTN Irancell. During 2022, we recorded US$559.37 in roaming revenues and US$0 (zero) of expenses payable to MTN Irancell under this agreement. See "—C. Organizational Structure—Disclosure Pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act" for further information.

#### Network sharing agreement
In December 2019, Telefônica Brasil and TIM had entered into two network sharing agreements regarding electronic equipment and mobile sites on 2G, 3G and 4G networks, in order to (i) decommission outdated technology; (ii) 4G coverage expansion; and (iii) gain spectrum and cost-efficiency. Both agreements were approved by ANATEL and CADE.

In December 2020, Telefônica Brasil and Claro S.A entered into a network sharing agreement in which the parties had agreed to share 81 of our mobile sites with Claro. The agreement was approved by ANATEL and CADE.

The approval of the aforementioned agreements, however, does not exempt the providers from fulfilling their obligations, nor from the coverage of the entire area. In the case such agreements are terminated before the expected deadline, each provider must meet its coverage commitments with its own network, under the penalty of extinction of the use of radio frequencies' authorizations.

See also "—Mobile coverage" above for further information on our network sharing.

#### Competition
Competition in the fixed and mobile markets continued to be intense in 2021. Faced with the high demand for connectivity, Brazilian telecoms have focused on modernization and innovation as levers to remain competitive in the market. The leading companies have been directing efforts and investments toward the digital transformation of business operations, aiming to improve the balance between customer growth and loyalty, revenue growth and margins. For these reasons, the major operators accelerated the 4.5G coverage, rolled out fiber and continued to include value-added services in the offers in order to differentiate their mobile and fixed portfolios. In addition, telecommunication companies began to leverage their customer base, billing and other key assets to engage in other revenue streams, alone or in partnerships with companies from other sectors. The initiatives remain in their initial steps and range from financial services, to healthcare, education and B2B solutions.

The Brazilian consumer market is increasingly knowledgeable and demanding, expecting not only the best service delivery, as well as the best cost-benefit. Therefore, operators have prioritized the expansion and digitalization of company-customer interactions.

In the mobile market, we continued to lead in market share, with a 38.9% share according to information from ANATEL as of December 31, 2022. This year, the competition remained intense in 4G and 4.5G network coverage expansion and subscribers' growth.

We lead the mobile market in 15 states: Alagoas, Amazonas, Amapá, Ceará, Espírito Santo, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Pará, Paraíba, Pernambuco, Rio Grande do Sul, Roraima, São Paulo and Sergipe. Claro Brasil or Claro is a mobile operator controlled by the Mexican company America Móvil Group, and leads mobile service in nine states: Acre, Bahia, Distrito Federal, Goiás, Maranhão, Piauí, Rio de Janeiro, Rondônia and Tocantins. TIM, a Brazilian telephone company and a subsidiary of Telecom Italia, leads the mobile market in three states: Paraná, Rio Grande do Norte and Santa Catarina (according to ANATEL as of December 2022).

On the fixed services front, the wireline and pay-TV services reported net disconnections, according to ANATEL. In broadband, the market continued to expand mainly in ultra-broadband and fiber accesses. Our main competitors in fixed telecommunications services are Claro (which includes its Claro and Embratel services) and Oi, which is stronger in the fixed-line services outside the State of São Paulo. TIM (a subsidiary of Telecom Italia) has been offering its fixed broadband network TIM Live in 40 cities. SKY, which is currently controlled by the Argentine conglomerate Werthein, has pay TV and broadband services (4G LTE TDD). In addition, we have competition from thousands of regional service providers throughout Brazil.

**Environment, Social and Governance**

By promoting digitalization, we bring people, businesses, and society together, contributing to transforming lives and companies. This objective is translated through our purpose 'Digitalize to Bring Closer', supported by strategic pillars, among them

[**Table of Contents**](#TOC)

#VivoSustentável, which includes actions to the well-being of society, promoting positive impacts from digitalization. To ensure and track this commitment, we have the Responsible Business Plan (RBP), a strategic instrument approved annually by the Board of Directors which establishes medium and long-term initiatives and goals based on six pillars that contribute to the Sustainable Development Goals/2030 Agenda.

This strategy is deployed through internal structures that ensure its perpetuity and dissemination across the organization, such as specific committees for ESG agendas with senior management: (a) Quality and Sustainability Committee (local and global) with the participation of independent members of the Board of Directors and (b) Sustainability Committee, with direct reporting to the CEO and the Executive Directors. In 2022, it was approved the new composition of our Board of Directors, achieving advances in terms of independent members (83.3% of the total members) and diversity (33.3% of the members are women).

To further strengthen the theme in the organization, ESG commitments are included in variable compensation. Since 2019, 20% of short-term executive and employee compensation are linked to NPS, reputation, GHG emissions and women in leadership targets. In 2022, a New Long-Term Incentive Plan was announced, which includes phantom shares of the Company in executive compensation, with climate change indicators among the evaluation criteria. Demonstrating how sustainability correlates with our business strategy and long-term vision, we issued R$3.5 billion in Sustainability-Linked Bonds (SLBs), a debt instrument linked to the achievement of ESG goals. The assumed goals relate to internal actions aimed at promoting diversity and a low-carbon economy.

On Climate Change, our performance is based on three pillars:

● *Mitigate impact:* we have an energy efficiency program to reduce our energy consumption; 100% of the electricity supply comes from renewable sources and currently, we are investing in Distributed Generation Projects, with more than 85 plants planned. We are also Carbon Neutral, offsetting direct emissions, and continue to reduce our own emissions. In the value chain, through its Carbon in the Supply Chain Program, CO2-intensive suppliers are engaged to reduce their emissions. The Telefónica global target, validated by Science Based Targets initiative (SBTi), is to reduce value chain emissions by 56% by 2030 and achieve net zero emissions by 2040.

● *Leverage Opportunities:* technology is crucial in the transition to a greener society. For this, we provide solutions that have the potential to decarbonize various value chains. In the B2B segment, we offer P&S with the Eco Smart seal, verified by a third party, which allows companies to know the environmental benefits that the solution can generate in their operation.

● *Adapt to Risks:* climate change risks are included in our overall risk assessment. Periodically, a qualitative and quantitative evaluation is performed, considering the physical and transition risks in short, medium and long term. 100% of the operations nationwide are evaluated.

For the disposal of electronic waste, since 2006, we offer to our customers and non-customers collection points where they can do the correct disposal through Recicle Com a Vivo Program, which has already collected more than 5 million items. We also raise awareness of society, with actions in various channels, such as prime-time TV commercials, social media and schools. With Vivo Renova Program, customers receive discounts for exchanging their cell phones upon delivery of the used device, which can be resold (increasing its useful life) or disposed of properly. In the fixed business (broadband, voice and TV), customers can schedule home collection or return to the store of used modems or decoders to be refurbished and reused or recycled. In addition to actions at the end of the product's life cycle, the company also provides the Eco Rating seal, which evaluates the cell phones' environmental performance, providing information for the consumers' sustainable purchasing and encouraging manufacturers to improve their products.

Aware of the benefits of digitalization, we invest around R$8 billion per year in strengthening our mobile network and expanding our fiber network. Digitalization also has the potential to promote social development and inclusion, accelerating the penetration of essential services. In this context, we have solutions in health (Vida V), education (VivaE), banking and access to credit (Vivo Pay and Vivo Money). Digitalization is part of the Fundação Telefônica Vivo purpose, which benefits more than 2 million people per year and has as one of its areas of focus the development of digital skills with public school teachers and students.

We have the Vivo Diversity Program, with an exclusive committee led by the CEO and actions to expand the inclusion and representativeness of four main groups: gender, race, LGBTI+ community and people with disabilities. In 2022, our internship and trainee program allocated 50% of positions to black people. We are committed to the targets: (1) ≥30% of blacks in leadership positions by 2027; (2) ≥40% of black people in the workforce by 2027; (3) 40% of women in executive leadership positions by 2027.

[**Table of Contents**](#TOC)

To achieve these goals, we have affinity committees and groups, exclusive mentoring programs, specific recruitment and selection practices, in addition to training actions for managers and employees.

In 2022, we updated our code of ethics, called Responsible Business Principles, which defines the basic values to act with integrity, transparency and commitment. These values are strengthened through the Compliance Program, called #VivoDeAcordo, with actions aimed at all employees. The ethical agenda is also expressed in our commitment to protecting our customers' data with high standards of privacy and security. The customers can access more information about the treatment of data, exercise of rights and details about our management practices through the Privacy Center website. Furthermore, the digital security strategy is monitored by senior management through: (a) a dedicated management structure with a Chief Security Officer (CSO) and a Chief Information Security Officer (CISO), (b) a Digital Security Risks Executive Committee, and (c) the periodic review of the digital security strategy by a Board of Directors' independent director.

We have implemented significant standards and certifications: ISO 26000 (Social Responsibility); ISO 27001 (Information Security) for the GVUL (vulnerability management) and MDR (Managed Detection and Response) process of the digital security program (Vivo Segura); DSC 10000 (Compliance); ISO 14001 (Environmental); ISO 45001 (Occupational Health and Safety) and ISO 50001 (Energy). Emphasizing its commitment to sustainable development, we also adhered to the 2030 Ambition of the UN Global Compact Network Brazil, an initiative aimed at expanding the engagement of companies in the implementation of the Sustainable Development Goals (SDGs).

we are placed in the main sustainability assessments, such as: (1) Among the 10 most sustainable companies in the sector in S&P's ESG Global ranking (ninth position) and second consecutive year in The S&P Sustainability Yearbook; (2) Present on the 'A List' of CDP Climate Change; (3) Top 5 in the Corporate Sustainability Index – ISE B3 (second position) and listed on other ESG indices from B3: ICO2 (Carbon Management), IGPTW (People Management) and S&P/B3 ESG Brazil; (4) Second consecutive year on the Bloomberg Gender-Equality Index (GEI); (5) TOP 10 in the ranking 'Best Companies to Work by Great Place to Work Brasil 2022'. In addition, the company is part of ESG indices of the S&P, FTSE4Good and MSCI.

Our ESG strategy, including main environmental, social and governance actions and programs, can be found in its Annual Sustainability Report, available on: https://ri.telefonica.com.br/en/esg/sustainability-reports. The information on our website is not a part of this annual report on Form 20-F.

#### Regulation of the Brazilian Telecommunications Industry
Our business, including the services we provide and the rates we charge, is materially affected by comprehensive regulation under the General Telecommunications Law and various administrative rules thereunder. We operate under authorization agreements for voice, mobile, data and Pay TV services in all Brazilian states, except for voice services in São Paulo state, where we operate under a concession agreement that enables us to provide specified services and subjects us to certain obligations, according to the PGMU and the RCON.

ANATEL is the regulatory agency established by the General Telecommunications Law and is administratively and financially independent from the Brazilian government. Any proposed regulation by ANATEL is subject to a period of public comment and, occasionally, public hearings, and its decisions may be challenged in Brazilian courts.

#### Concessions and authorizations
In accordance with the General Telecommunications Law, concessions are licenses to provide telecommunications services granted under the public regime, while authorizations are licenses to provide telecommunications services granted under the private regime.

Both concessions and authorizations licenses are subject to several obligations regarding, for instance, quality of service, as well as network expansion and modernization. Nonetheless, companies that provide services under the public regime, known as the concessionaires, are subject to additional obligations as to continuity and universality of service.

[**Table of Contents**](#TOC)

A concession may only be granted pursuant to a public bidding process. As a result, regulatory provisions are included in the relevant concession agreements and the concessionaire is subject to public service principles of continuity, changeability and equal treatment of customers. In addition, ANATEL is authorized to direct and control the provision of services, to apply penalties and to declare the expiration of the concession and the return of the possession of the reversible assets from the concessionaire to the government authority upon termination of the concession. Another distinctive feature of public concessions is the right of the concessionaire to maintain economic and financial standards, which are calculated based on the rules set forth in our concession agreement and was designed based on a price cap model.

On October 4, 2019, the New General Telecommunications Law was enacted. This law revises the telecommunications regulatory framework and represents a significant impact on this industry. For more information about the New General Telecommunications Law, see "—Other regulatory matters—Updated regulatory framework".

The companies that operate concessions under the public regime are Telefônica Brasil, Oi, Algar, Sercomtel and Claro (Claro for domestic and international long-distance service). These companies provide fixed-line telecommunications services in Brazil that include local and long-distance services (domestic and international). All other telecommunications service providers, including the other companies authorized to provide fixed-line services in our concession region, operate pursuant to authorizations under the private regime. Companies that provide services under the private regime, known as authorized companies, are not subject to the same requirements regarding continuity or universality of service; however, they may be subject to certain network expansion and quality of service requirements that are obligations set forth in their authorizations. Authorizations are granted for an indeterminate period. Under an authorization, the government does not provide a guarantee to the authorized company of a financial-economic equilibrium (*equilíbrio econômico-financeiro*), as is the case under concessions. Fixed voice authorization license holders are entitled to freely compete with the concessionaires in their respective areas without any limitation.

An authorization is a license granted by ANATEL under the private regime, which may or may not be granted pursuant to a public bidding process, to the extent that the authorized company complies with the objective and subjective conditions deemed necessary for the rendering of the relevant type of telecommunication service in the private regime.

The General Telecommunications Law delegates to ANATEL the power to authorize private regime companies to provide local and intraregional long-distance services in each of the three fixed-line regions and to provide intraregional, interregional and international long-distance services throughout Brazil. ANATEL has already granted authorizations for companies to operate in Region III, our concession region. ANATEL has also granted other authorizations for companies to operate in other fixed-line regions and authorizations to provide intraregional, interregional and international long-distance services throughout Brazil competing with Claro, which operates under a long-distance fixed-line concession.

Concessionaires, including us, can also offer other telecommunications services in the private regime, which primarily include broadband, data transmission services, mobile services and Pay TV.

#### Obligations of telecommunications companies
Pursuant to the concessions and authorizations, we and other telecommunications service providers are subject to obligations concerning quality of service, network expansion and modernization. Telecommunication concessionaires are also subject to a set of special restrictions regarding the services they may offer, which are listed in the General Grants Plan (*Plano Geral de Outorgas* – PGO), and special obligations regarding network expansion and modernization contained in the PGMU.

In January 2017, ANATEL held a public consultation relating to the new rules of the PGO containing an exclusive chapter aimed at verifying the migration of fixed telephony concessions for authorizations, in accordance with the new legal framework discussed in the Congress at that time. However, the changes in the General Telecommunication Law were approved only in October 2019. Despite ANATEL's efforts in 2017, a series of regulations to create the conditions proposed under the new Law must be prepared and revised.

Any breach of telecommunications legislation or of any obligation set forth in concessions and authorizations may result in a fine of up to R$50 million per infraction.

[**Table of Contents**](#TOC)

Our operations are regulated as follows:

● Fixed line voice services (local and long-distance) under concession agreement in the state of São Paulo and under authorization agreement in the rest of the Brazilian territory. The concession was granted in 1998 by the Brazilian Government and renewed in December 2005 for an additional period of 20 years. It authorizes us to provide fixed-line telecommunications services in the state of São Paulo, except for a small area (Sector 33) and to place and manage public telephones in our concession area. We also provide fixed-wireless services throughout our concession area, for which the authorization was granted in 2001 by the Brazilian Government for the whole Brazilian territory;

● Mobile voice and mobile broadband services, in all 26 states and the Federal District, under the personal mobile service (*Serviço Móvel Pessoal - SMP*) authorizations;

● Fixed broadband and Multimedia communication services, such as audio, data, voice and other sounds, images, texts and other information throughout Brazil. We operate under a nationwide SCM authorization, valid for an indefinite term;

● Pay TV services, throughout all regions of Brazil under the conditioned public service (*Serviço de Acesso Condicionado*), or SeAC authorization. We operate a SeAC authorization, which is valid for an indefinite term;

● Private Limited Services – SLP, which accounts for the provision of telecommunication services in the private regime, intended for network building and specific groups of users defined by the provider and which covers multiple applications, including data, video, audio, voice and text communication; and

● Wholesale services, such as interconnection, governed by the interconnection agreements discussed under "—Operating Agreements—Interconnection Agreements," industrial dedicated line (*Exploração Industrial de Linha Dedicada – EILD*), which are regulated by ANATEL Resolution No. 590, dated May 15, 2012 and Mobile Virtual Network Operator, or MVNO agreements described under "—Operating Agreements—MVNO Agreements". Most wholesale services are also regulated by the PGMC.

We set forth below details of the concession, authorizations, licenses and regulations that regulate our operations.

*Quality regulations in Brazil*

In December 2019, ANATEL approved the new RQUAL, which changes the way the agency will monitor the performance of telecommunications operators. In addition to promoting quality indicators increasingly associated with consumer experience and widespread dissemination of results, the concept of responsive regulation was introduced, encouraging advanced corrective actions to problems, rather than solely imposing fines when goals are not met. Providers will be evaluated for certain quality requirements and will receive annual "seals" from "A" to "E" in each Brazilian municipality. If the provider has quality deterioration in a municipality compared to the previous label and is in the last two positions (seals D or E), customers may terminate their contracts without paying penalties (if the service was contracted at the time the provider's quality seal was superior). Seals will be awarded annually with quality measurements per municipality and state, as well as Brazil as a whole, based on three indicators: quality of service index, perceived quality index and user complaint index.

An independent entity, funded by the providers, will measure the quality of services, but ANATEL will be able to contract complementary measures. In addition to this entity, the regulation amended the consumer rights regulations, creating the obligation to establish an ombudsman, directly linked to the company's presidency. The full implementation of this new regulation will not take place until 2022. ANATEL has set a deadline of 18 months for its implementation group to develop an operational manual, making the first measurements, and for the publication of a reference values document, or DVR. As the DVR was approved on December 2, 2021, measurements begun on March 2022, and seals are expected to be issued in early 2023

RQUAL already revoked most of the existing indicators in the old quality regulations. The reimbursement criteria in the services regulations were also revoked, and, as of February 2022, only the RQUAL provisions are in force.

[**Table of Contents**](#TOC)

#### Fixed-line services
*Our concession agreement*

We are authorized to provide fixed-line services to render local and domestic long-distance calls originating in Region III, which comprises the state of São Paulo, except for Sector 33, established in the PGO. The current concession agreement that is valid until December 31, 2025 was reviewed in 2006 and 2011. According to Resolution No. 678/2017, a new revision should have been until December 31, 2020, which has not yet occurred. Until then, our 2011 contract remains valid.

Other regulations have been adopted to revise certain aspects of our concession. On June 30, 2011, ANATEL determined the new basis for calculation of the biannual concession fees. Every two years, during the new 20-year period of our concession, we are required to pay a renewal fee, which amounts to 2% of the total revenue in the previous year, calculated based on the revenues and social contribution of fixed-line basic and alternative plans. The most recent payment of this biennial fee was made in April 2019, based on 2018 revenue. The next payment is therefore scheduled for 2021 based on 2020 revenue. See Note 1 to our Consolidated Financial Statements.

In addition, the Brazilian government published Decree No. 7,512/2011 which enacted PGMU III. It set forth new targets for public pay phones (*Telefone de Uso Público*) availability in rural and low-income areas and targets related to low-income fixed-line services (*Acesso Individual Classe Especial – AICE*).

On June 27, 2014, ANATEL held a public consultation for the PGMU. Since there was no mutual agreement between ANATEL and operators for the signature of the 2015 concession agreement contracts, the new version of the PGMU was also delayed. In December 2018, although the new concession contracts have not yet been signed, the Brazilian government published Decree No. 9,619/2018, which approves the revision of the PGMU targets. The new plan replaces some obligations, mainly related to public telephony, for obligations related to the 4G mobile network. These targets have been criticized by several local operators.

In addition, in December 2018, ANATEL began a notice and comment period on the last PGMU revision for the period between 2021 and 2025 (PGMU V). The public consultation was concluded and ANATEL's board of directors approved the new revision on November 26, 2020. The main change in comparison to PGMU IV concerns the goals that must be met to replace the reduction in the number of payphones required. ANATEL proposed to replace 4G targets, established in the previous plan, with the construction of a backhaul in municipalities that do not have an optical fiber connection yet. These targets were approved by the Brazilian Ministry of Communications (*Ministério das Comunicações*) in January 2021 through Decree No. 10,610/2021. Additionally, ANATEL published Resolution No. 754/2022, containing the revised PGMU Regulation.

Our concession agreements provide that all assets owned by us, and which are indispensable to the provision of the services described in such agreements, are considered "reversible assets" (*bens reversíveis*) and are deemed to be part of the concession assets, subject to reimbursement or amortization as compensation for these assets. In 2021, with the publication of Resolution No. 744, ANATEL established that, upon the end of an STFC concession contract, reversible assets used for several services, including our public regime STFC services, would be subject to a right-of-use assignment, under fair and reasonable economic conditions, by us and the new service provider or the Brazilian government. In turn, the possession of reversible assets that are effectively and exclusively used to ensure the continuity of public regime STFC would be reverted to the granting governmental authority if the service continues to be provided (either by the Brazilian government or by the new concessionaire service provider). As such, at the end of our concession contract on December 31, 2025, our concession-related assets will not be transferred to the Brazilian government, but will be subject to specific network and infrastructure sharing agreements as provided in the operational manual for the Continuity Regulation, which itself was approved by Decision No. 269/2021/COUN/SCO. Nevertheless, it is important to emphasize that in the scope of administrative proceeding TC nº. 003.342/2022-0, in progress at the Federal Court of Accounts, a technical report stated that the RCON should be reviewed, such understanding shall still be submitted to the court's ruling.

For information about regulations affecting rates we can charge under our concession agreements, see "—Rates, Taxes and Billing."

*Obligations on concessionaires to provide fixed-line service under the public regime*

We and the other concessionaires are subject to the General Universal Service Targets Plan (*Plano Geral de Metas de Universalização – PGMU*), which requires that concessionaires undertake certain network expansion activities with respect to fixed-

[**Table of Contents**](#TOC)

line services. The timing for network expansion is revised by ANATEL from time to time. If any given concessionaire does not fulfill its obligations under the PGMU, ANATEL may impose various monetary penalties and such concessionaire may lose its license if ANATEL determines that it will be unable to provide basic services under the Plan.

*Fixed line service under the private regime*

In 2002, we began providing local and interregional services in Regions I and II and Sector 33 of Region III, and international long-distance services in Regions I, II and III, which constitute regions in Brazil that are outside of our public regime concession area.

#### Mobile services
In October 2016, ANATEL approved new spectrum use regulations, which facilitate access to radio frequencies and generates efficiency in its use, due to the simplification of procedures and necessary documentation. The regulation also alters spectrum pricing (for non-bidding grants), rules for extending use authorization and new rules for frequency use on a secondary basis prior to primary use.

In July 2018, ANATEL approved Resolution No. 695, which establishes new spectrum pricing regulations, with calculation methods and conditions for spectrum reserve prices and renewal costs. This new regulation took effect in May 2019.

In November 2018, ANATEL approved Resolution No. 703, which establishes new spectrum cap regulation. There are two groups of bands with specific limits for a given area:

● Frequencies up to 1 GHz: each operator may hold up to 35% of the bands;

● Frequencies between 1 GHz and 3 GHz: each operator may hold up to 30% of the bands.

These limits can be extended by up to 40%, through competitive constraints that may be imposed by ANATEL. For frequencies above 3.0 GHz, the limits were determined in the specific auction terms as follows:

● 3.5 GHz frequency (between 3.3 and 3.7 GHz): each operator may hold up to 100 MHz of the band;

● 26 GHz frequency (between 24.3 GHz and 27.5 GHz): each operator may hold up to 1 GHz of the band.

*Mobile service licenses (SMP)*

Previously, spectrum authorizations were valid for 15 years and could only be renewed once. Although the recently approved New General Telecommunications Law permits successive spectrum renewals, we cannot guarantee that our existing licenses will be renewed.

According to the New General Telecommunications Law and to Decree No. 10,402/2020, ANATEL may set specific conditions for the renewal of our existing licenses on the grounds of efficient spectrum use, competition issues or public interest. For example, ANATEL can impose a mandatory "refarming" processes in certain spectrum bands or refuse renewal requests altogether. A refarming process can reduce the amount of spectrum available for each operator, depending on the configuration of the new blocks.

Our current 850 MHz authorizations will expire between 2022 and 2028. If legal and regulatory requirements are met, ANATEL has agreed to the current authorizations for the use of radio frequencies in bands A and B, on a primary basis, until November 29, 2028. However, the specific conditions for renewal, including those related to economic valuation criteria and related obligations, were challenged by the affected service providers, including us. After ANATEL rejected complaints presented by the providers, a final disposition of the matter is still pending and will require a decision by the TCU.

Furthermore, since our licenses for the 900 MHz and 1,800 MHz band will expire in 2023, their renewal has been requested and a final decision by ANATEL is still pending. For instance, in August 2022, ANATEL approved the renewal of 900 MHz and 1,800 MHz licenses held by TIM until 2032.

[**Table of Contents**](#TOC)

In addition, on December 8, 2022, ANATEL revoked our 450 MHz spectrum authorization (451-458 MHz and 461-468 MHz) covering the states of Alagoas, Ceará, Minas Gerais, Paraíba, Pernambuco Piauí, Rio Grande do Norte, Sergipe and part of São Paulo. The decision was motivated by the fact that we could not provide evidence of service activation in the 450 MHz band as a result of the unavailability of 450 MHz devices ecosystem and of the waiver clause contained in the tender notice, interpreted by ANATEL as meaning that the waiver would operate automatically in case of non-activation of the frequency within the contractual term. Previously, in September 2022, ANATEL revoked authorizations held by other providers.

Typically, renewed licenses required payment of 2% of net operating revenues earned in the region included in the authorization, every two years for the duration of the extension period. For some licenses, we also must pay 1% of the aforementioned amount in the 15th year. In July 2018, however, ANATEL published Resolution No. 695 with a new Public Spectrum Price Regulation. The Resolution establishes new criteria for license renewal costs. The formula considers factors such as grant time, revenue earned in the region and the amount of spectrum used by the company. Part of the payment can be converted into investment commitments.

Our SMP authorizations include the right to provide mobile services for an unlimited period but restrict the right to use the spectrum according to the schedules listed in the respective radiofrequency authorizations. The table below sets forth our current SMP authorizations, their locations, band and spectrums, date of issuance or renewal and date of expiration:

&nbsp;&nbsp;&nbsp;&nbsp;(2) States of AC, AM, AP, BA, DF, ES, GO, MA, MG, MS, MT, PA, PR, RJ, RO, RR, RS, SC, SE, SP and TO - except PGO Sectors 3, 22, 25, 30 and 33.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Current licenses expire between 2022 and 2028. ANATEL decided to limit their renewal up to 2028, due to a future mandatory refarming process.

&nbsp;&nbsp;&nbsp;&nbsp;(4) States of AC, AM, AP, BA, DF, ES, GO, MA, MG, MS, MT, PA, PR, RJ, RO, RR, RS, SC, SE, TO - except PGO Sectors 20, 22, 25 and 30.

&nbsp;&nbsp;&nbsp;&nbsp;(5) Regional licenses: expiration and renewal dates depend on the region.

&nbsp;&nbsp;&nbsp;&nbsp;(6) 20 MHz is the most common bandwidth, but can rise up to 50 MHz in some regions.

&nbsp;&nbsp;&nbsp;&nbsp;(7) 30 MHz in regions where the 1,900 MHz bandwidth frequency has been migrated to 2,100 MHz.

&nbsp;&nbsp;&nbsp;&nbsp;(8) 50 MHz in the southeast region of Brazil (except the state of SP and PGO Sector 3); 40 MHz in the state of SP, and in the north and mid-west regions of Brazil (except PGO Sectors 22 and 25).

&nbsp;&nbsp;&nbsp;&nbsp;(9) 40 MHz is the most common bandwidth, but can rise up to 60 MHz in some regions.

&nbsp;&nbsp;&nbsp;&nbsp;(10) Band X will expire in 2027 and Band P will expire in 2031.

In 2013, we changed the terms of our authorization regarding Band "L" (1.9 GHz) in certain locations, adapting their blocks of frequencies to 2.1 GHz and aligning them with the Band "J" (3G), which enables more efficient use of the spectrum. In 2018, this alignment process was completed at the national level with respect to the following areas: Northeast region, with the exception of Bahia and Sergipe; Pelotas, Morro Redondo, Capão do Leão and Turuçu, in Rio Grande do Sul; Buriti Alegre, Cachoeira Dourada, Inaciolândia, Itumbiara, Paranaiguara and São Simão, in Goiás; Altinópolis, Aramina, Batatais, Brodowski, Buritizal, Cajuru, Cássia dos Coqueiros, Colômbia, Franca, Guaíra, Guará, Ipuã, Ituverava, Jardinópolis, Miguelópolis, Morro Agudo, Nuporanga, Orlândia, Ribeirão Corrente, Sales de Oliveira, Santa Cruz da Esperança, Santo Antônio da Alegria and São Joaquim da Barra in São Paulo; and

[**Table of Contents**](#TOC)

Paranaíba in Mato Grosso do Sul. This change is foreseen in the bidding document No 001/2007. We do not have Band "L" in the states of Amazonas, Roraima, Amapá, Pará and Maranhão and in the cities of Londrina and Tamarana, Paraná.

In 2012, Telefônica acquired 40MHz on the 2.5GHz to 2.69GHz frequencies for the amount of R$1.05 billion. In order to meet the coverage requirements imposed by ANATEL, we had the obligation of implementing 4G coverage in 1,094 cities by December 31, 2017. The remaining coverage commitments in cities with less than 30,000 inhabitants could be fulfilled with other frequency bands until December 31, 2019. ANATEL is responsible for verifying compliance with such targets and has not yet completed its review of our compliance with our coverage commitments for the year ended December 31, 2019.

Currently, we have made 4G services available in over 3,100 municipalities. Telefônica has deployed and continues to deploy 4G coverage by serving its customers through the use of its own network or by established agreements of RAN-sharing approved by ANATEL.

We also have the obligation to meet voice and data demand in remote rural areas, defined in the bidding process of the 2.6 GHz band. As a commitment, we are required to provide infrastructure and service operating in any frequency band in rural areas in the states of Alagoas, Ceará, Minas Gerais, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, Sergipe, and countryside of São Paulo, for a total of 2,556 municipalities. In these areas, we are also required to provide free broadband to schools located in rural areas.

Regarding the 700MHz spectrum, ANATEL has allocated the band for the provision of fixed, mobile and broadband services. On September 30, 2014, we acquired 20 MHz (10+10 MHz) with nationwide coverage, for R$1.92 billion, at the minimum price, plus R$904 million for the band cleaning (migration of broadcasters that currently occupy the band and interference management). According to the auction rules, the winning bidders are responsible for financing and managing the band cleaning process (Analog TV switch off) which was implemented through a legal entity specifically incorporated for this purpose, as set forth in the bidding process and applicable regulations (EAD).

Since June 2019, all Brazilian municipalities are ready to activate LTE coverage in the 700 MHz band. In November 2020, ANATEL attested that 9 out of 17 obligations have been fulfilled by the operators. According to the Agency, the other obligations would either be concluded in 2020 or were linked to activities that still need to be carried out, however, this situation does not imply any type of noncompliance on the part of the operators in relation to what should have been done.

In December 2015, ANATEL auctioned the remaining spectrum lots in the 1,800 MHz, 1,900 MHz and 2,500 MHz bands, from which Telefônica acquired seven lots of 2.5 GHz frequency band offering a total of R$185.4 million. These lots are associated with six different States, in the capital cities of the States of São Paulo, Rio de Janeiro, Porto Alegre, Florianópolis, and Palmas, and one countryside city of the State of Mato Grosso do Sul. Such frequencies are already being used for the provision of mobile broadband service on 4G.

In November 2021, ANATEL held the largest spectrum auction in its history, which included 4G and, for the first time, 5G blocks, with 700 MHz, 2.3 GHz, 3.5 GHz and 26 GHz lots. On that occasion, we acquired 3.5 GHz and 26 GHz national licenses (100 MHz and 600 MHz bandwidths, respectively). We also won regional 2.3 GHz licenses, with 50 MHz bandwidth in the southeast region of Brazil (except São Paulo state and PGO Sector 3) and 40 MHz bandwidth in São Paulo state and in the north and mid-west regions of Brazil (except PGO Sectors 22 and 25). These acquired licenses, which we purchased for a total of R$4.45 billion, of which R$0.93 billion is related to licenses and the remaining amount related to the obligations ANATEL set forth. The licenses ensure we have the required spectrum to provide 5G services, and are valid for 20 years (renewable under the then-existing legal conditions at the expiration of this term).

#### Multimedia communication service
Our multimedia services include broadband in several technologies, including fiber UBB services.

We have assumed in the past the obligation to provide free Internet access to public schools in the area comprising in our concession area during the term of the concession agreement (until 2025). The number of schools for which we should provide broadband is determined by the school census provided by the National Education Ministry, which is published on a yearly basis or sometimes in longer intervals. Our obligation targets are adjusted according to the latest census released.

[**Table of Contents**](#TOC)

***Pay TV services***

We are authorized to provide Pay TV Services (*Serviço de Acesso Condicionado*), or SeAC, throughout Brazil by means of different technologies (Fiber, DTH and coaxial)*.*

Law No. 12,485/2011 established the most important aspects of this service, including the imposition of minimum national content requirements, carrier obligations and rights and cross-ownership restrictions.

Since 2019, the Brazilian Congress has been discussing bills amending SeAC law. Among the proposals is the review of limitations to cross-control between telecom providers and content producing and programming companies. Regulatory asymmetries between SeaC and OTT services are also under debate.

#### Interconnection fees
In accordance with ANATEL regulations, we must charge fees to the other telecommunications service providers based on the following:

● a fee for the use of our local, fixed-line service network (the TU-RL): we charge local service providers an interconnection fee for every minute used in connection with a call that either originates or terminates within our local network, with the exception of calls between other providers of local, fixed-line service, for which a fee is not charged;

● a fee for the use of our long-distance, fixed-line service network (the TU-RIU): we charge long-distance service providers an interconnection fee on a per-minute basis only when the interconnection access to our long-distance network is in use;

● a fee for the use of the mobile network (the MTR): we charge mobile service providers an interconnection fee on a per-minute basis only when the interconnection access to our mobile network is in use; and

● a fee for the use of leased lines by another service provider (EILD): we also lease transmission lines, certain infrastructure and other equipment to other providers of telecommunications services.

For more information, see "Item 3. Key Information—D. Risk Factors—Risks Relating to the Brazilian Telecommunications Industry and Us—Our results of operations may be negatively affected by changes to STFC or SMP rules."

*Fixed-line services*

In July 2005, ANATEL published new rules on interconnection. The main changes are: (i) an obligation to have a public offering of interconnection for all services, in addition to interconnection fees between providers of fixed-line and mobile telephone services; (ii) an obligation by internet backbone providers to publicly offer interconnections; (iii) the establishment of criteria for the treatment of fraudulent calls; and (iv) a reduction of service times for interconnection requests.

In 2006, we completed the implementation of interconnection with mobile service providers in regions with heavier traffic, ensuring proper billing for such calls. This reduced interconnection costs.

In 2007, ANATEL published a new version of its fixed-line network compensation regulation, which changed the rules used to calculate interconnection fees. Local and long-distance fees, which were hitherto fixed, became variable fees according to the rules for public service fees. A 20% increase was applied to fees for mobile service operators without significant market power in their regions.

On May 7, 2012, ANATEL Resolution No. 588/2012 was published, which set forth the following:

● a maximum of two minutes of interconnection should be paid for the use of the local network on reduced hours;

● a reduction of interconnection fees from domestic and international long-distance calls by 30% of the TU-RL, and a reduction of 25% (until 2012) and 20% (as of 2013) of the TU-RIU;

[**Table of Contents**](#TOC)

● The remuneration between networks will not occur until this traffic imbalance is greater than 75% compared to 25%; and

● The partial Bill & Keep by December 31, 2013 and full Bill & Keep by December 31, 2014.

On July 1, 2014, ANATEL decided to gradually decrease the TU-RL, and the TU-RIU based on a bottom-up cost model by setting maximum rates for fixed interconnection fees for the years 2016 through 2019. In December 2018, ANATEL set the fixed-line interconnection fees ranging for the years 2020 through 2023, as shown in the table below for our STFC sector (Sector 31) *in reais*):

---

| | | | | |
|:---|:---|:---|:---|:---|
| |  | **Interconnection fees for Sector 31** | **Interconnection fees for Sector 31** | **Interconnection fees for Sector 31** |
| <br>**Year** |  | **TU-RL** | **TU-RIU1** | **TU-RIU2** |
| 2020 |  | 0.00134 | 0.00166 | 0.00118 |
| 2021 |  | 0.00117 | 0.00176 | 0.00120 |
| 2022 |  | 0.00104 | 0.00183 | 0.00122 |
| 2023 |  | 0.00096 | 0.00188 | 0.00122 |

---

In December 2016, ANATEL held a public consultation to discuss a new interconnection regulation (*Regulamento Geral de Interconexão*). These rules were eventually enacted in July 2018 through Resolution No. 693. The new rules seek to resolve a large number of disputes in agreements for voice and data traffic among telecom companies. In the case of a default, interconnection services can be cut without ANATEL's prior authorization. In addition, the rule sets forth a list of prohibited practices in interconnection relationships and makes interconnections technology-neutral.

*Mobile service*

In November 2009, ANATEL unified the licenses of all mobile operators, resulting in the consolidation of interconnection fees and reducing the number of fees for the use of the mobile network from two to one. On July 1, 2014, ANATEL decided to gradually decrease the MTR, based on a cost model for the years 2016, 2017, 2018 and 2019. In December 2018, ANATEL established the reference values for the MTR for the years ranging from 2020 until 2023, as shown below per region in the General Authorization Plan (*Plano Geral de Autorizações*), or PGA, in *reais*:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| **Year** |  | **PGA Region I** |  | **PGA Region II** |  | **PGA Region III** |
| 2020 |  | 0.01338 |  | 0.01503 |  | 0.02687 |
| 2021 |  | 0.01380 |  | 0.01527 |  | 0.02814 |
| 2022 |  | 0.01422 |  | 0.01550 |  | 0.02947 |
| 2023 |  | 0.01468 |  | 0.01578 |  | 0.03082 |

---

In addition, on December 2, 2013, Act No. 7,272 was published, which set the MTR reference values for PMS providers and became effective on February 24, 2014. On August 28, 2014, Nct no. 7,310 replaced the reference values previously set out in Act No. 7,272. In addition, the PGMC determined that in the relationship among PMS and non-PMS providers in the mobile network, the interconnection fee should be paid only when the traffic out of a network in a given direction is greater than 80% of the total traffic exchanged until February 23, 2015; and 60% of the total traffic exchanged from February 24, 2015 to February 23, 2016. Since February 24, 2016, the MTR is owed to the mobile service provider when its network is used to originate or terminate calls (full billing). These conditions were further modified by ANATEL in February 2015, after public notice and comment. In July 2018, ANATEL amended the PGMC and modified the rules on interconnection fees to be paid for outbound traffic, as follows:

● From January 1, 2013 to February 23, 2015: 80% / 20%;

● From February 24, 2015 to February 23, 2016: 75% / 25%;

● From February 24, 2016 to February 23, 2017: 65% / 35%;

● From February 24, 2017 to February 23, 2018: 55% / 45%; and

● From February 24, 2018 onwards: 50% / 50%.

[**Table of Contents**](#TOC)

*EILD*

On May 18, 2014, ANATEL approved the proposed standard for setting maximum values of Industrial Dedicated Line (EILD), based on Cost Models. Values for EILD were published through Act No. 6212, which contains a single reference table that is valid from 2016 until 2019. In addition, the general competition plan requires companies with significant market power to present a public offer every six months informing standard commercial conditions, which is subject to approval by ANATEL.

On December 17, 2018, ANATEL approved through Act No. 9,920 a revision of the EILD reference table, valid for 2020 onwards.

*Mobile Virtual Network Operator (MVNO)*

In 2001, ANATEL approved rules for companies to be licensed as MVNOs. In 2016, ANATEL authorized MVNO companies to be affiliates of other certain network operators, and for that reason, we have signed agreements with companies authorized to operate as an MVNO in Brazil. Brazilian MVNO regulations allow two operating models: "authorized" (in which MVNO holds its own SMP authorization but operates under an MNO's network) and "accredited" (in which the company doesn't hold an SMP authorization and acts as an MNO's representative and offers services jointly). In August 2019, ANATEL held a public consultation about regulatory barriers to IoT expansion and proposed changes in MVNO regulations. Furthermore, in November 2020, ANATEL Resolution No. 735/2020 reduced regulatory restrictions on the "accredited" model, and permitted the representation of multiple MNOs and gave more autonomy in the use of network agreements.

#### Internet and related services in Brazil
In Brazil, Internet service providers, or ISPs, are deemed to be suppliers of value-added services and not telecommunications service providers. ANATEL requires SCM operators to act as carriers of third-party internet service providers.

*Civil rights framework for the Internet*

On April 23, 2014, at the opening of NetMundial, former President Dilma Rousseff approved the Civil Rights Framework for the Internet (*Marco Civil da Internet*), which was enacted as Law No. 12,965/2014. The act adopts strict Net Neutrality rules that guarantee equality of treatment for data traffic in the network and preserves the business model of Brazilian broadband offered in packages with different speeds. After three public consultations released by CGI.br (the Brazilian Internet Steering Committee), the Ministry of Justice and ANATEL, the Brazilian government published Decree No. 8,711/2016, which regulates the law. It establishes the regulation for Net Neutrality and mechanisms to protect the data stored by service and application providers, as well as determining the circumstances in which data can be obtained by the public administration. We believe these measures will offer our clients greater protection with respect to how their personal information is used and shared and creates opportunities for new services that make use of aggregated information.

In June 2016, the Brazilian House of Representatives put into consultation a draft of law regarding Personal Data Protection. The original text of this law is based on the European Union's Directives on Data Protection (Directive 95/46/EC), and as such, imposes restrictive rules on the express consent to process personal data, international data transfer, processing of sensitive data, among others. In 2018, the President of Brazil approved the LGPD, which came into force on September 18, 2020, a comprehensive data protection law establishing the general principles and obligations that apply across multiple economic sectors and contractual relationships. Certain aspects of the LGPD will be subject to further regulation by the ANPD, in accordance with the ANPD's Ordinances No. 11/2021 and 35/2022. In addition, the administrative sanctions provided for in the LGPD (arts. 52, 53 and 54), came into force on August 1, 2021, pursuant to Law No. 14,010/2020. Furthermore, following the approval of Decree No. 10,474/2020, which governs the ANPD, all five directors were appointed and officially confirmed by the Brazilian Senate in October 2020.

[**Table of Contents**](#TOC)

In March 2021, the ANPD and the Brazilian National Consumer Secretariat (*Secretaria Nacional do Consumidor*), or SENACON, signed a technical cooperation agreement, or TCA, to facilitate the investigation of security incidents. Under the TCA, SENACON will begin sharing information about consumer complaints related to data protection with the ANPD. However, whether to apply the LGPD to individual cases, or whether to share information about these cases with SENACON, falls upon the ANPD. The TCA is effective for 24 months, subject to renewals at the ANPD and SENACON's discretion. In addition, ANPD signed a second TCA with CADE in June 2021, which seeks to target violations of economic and market rules and to promote a culture of free enterprise in services relating to the protection of personal data. To this end, CADE and the ANPD will exchange information and participate in joint educational activities on procedures and practices to promote competition in personal data protection services. In October 2021, ANPD signed a Memorandum of Understanding with the Spanish Data Protection Authority to promote specific technical cooperation mechanisms that allow the exchange of knowledge and experiences, as well as the identification of best practices in the field of personal data protection.

For additional information on our data protection and data privacy policies and procedures, see "Item 16g. Corporate Governance—Corporate Governance Practices—Data Protection and Privacy Initiatives."

#### Resolutions published

● ANATEL Public Consultation No. 86: Amends the Act containing operational requirements for the use of the frequency band between 3,300 MHz and 3,700 MHz, for harmonious coexistence between 5G systems and radio altimeters.

***Other regulatory matters***

*Regulation for competition*

In December 2016, ANATEL launched a public consultation for a regulation that set price references for wholesale products. The proposal would set the ANATEL cost model as the only source for the valuation of these products. In July 2018, ANATEL approved amendments to the PGMC through Resolution No. 694/2018. The rule creates a new relevant market (high-capacity data transfer) and introduces the concept of retail competitiveness levels for each municipality (ranging from category one, fully competitive, to category four, non-competitive areas where public policies are necessary to enable services). For each relevant market, asymmetric measures may vary according to the competition category assigned to each municipality. In addition, the new PGMC defines small-scale providers (*prestadora de pequeno porte*), or PPP, which ANATEL factors when creating asymmetric rules (in the context of PGMC and possibly in other regulations). Under the definition set by ANATEL, PPP designation applies to any company that does not account for more than 5% of the retail market share in which it operates.

*Productivity factor*

The X Factor is a regulatory instrument used to incentivize operational efficiency gains in the telecommunications sector, so that related gains in earnings are shared with the consumer through annual tariff readjustments. The X Factor's calculation mechanism, including the inputs and products relating to our applicable operations that are included in the calculation, are set by ANATEL. In October 2017, ANATEL approved a new methodology to calculate the X Factor for fixed-line telephone services. The new regulation uses a cost-based model to segregate revenues and costs for services. Under the new formula, although gains for retail broadband services were excluded, the methodology continues to consider the productivity gains of services rendered under the fixed voice authorization. Although this standard represents an evolution in the calculation methodology with the exclusion of gains in retail broadband services, there is still what we regard as an undue inconsistency when factoring in the productivity gains of the fixed voice authorization because the calculation does not distinguish between fixed voice services provided under the public and the private regime. We have voiced our opposition to the method for calculating the X Factor on a number of occasions. Although we have not initiated any formal proceedings with respect to this issue before ANATEL, we have expressed our criticism of this issue during the public consultation phase that preceded formal adoption of the standard, and annually each time we deliver our data to ANATEL for its calculation of our X Factor.

[**Table of Contents**](#TOC)

*Updated regulatory framework*

On October 4, 2019, the New General Telecommunications Law was published. This law revises the General Telecommunications Law and significantly impacts the industry.

The New General Telecommunications Law permits fixed-line concessions operators to migrate from a concession regime (in which the underlying assets must be reverted to the government at the end of the concession) to an authorization regime. ANATEL will be responsible for estimating the gains obtained by operators as a result of migrating from one regime to the other. According to the Law, on July 5, 2022, ANATEL presented a methodology with an estimate of the economic value associated with the adaptation of the concession instrument for authorization, to be validated by the Federal Court of Accounts, which after the vote of the rapporteur minister for the legality of the methodology presented by ANATEL, is under analysis by another minister, and should resume to the court's agenda in March. After the final decision by the Federal Court of Accounts about the methodology applied, ANATEL will indicate the final amount to the adaptation of the concession instrument for authorization. This final amount, after confirmation and acceptance by us, will be converted into investment projects not yet defined by ANATEL.

Furthermore, the New General Telecommunications Law also permits the successive renewal of an authorization to explore a spectrum, so long as ANATEL's requirements and stipulations are met. Under the previous model, each authorization could be renewed only. In addition, New General Telecommunications Law permitted the creation of a secondary spectrum trading market among authorized operators, where trades can be placed directly between them. Similarly, companies holding the rights to explore Brazilian satellite positions can have their permits renewed on an unlimited basis. However, these aspects of the law are still subject to implementation through regulations, which have yet to be passed.

Finally, under the New General Telecommunications Law, the FUST law was revised to clarify that radio and video broadcasting services are not subject to taxation under the FUST.

*Telecommunications Self-Regulation System* 

In March 2020, we and the main telecommunications service providers in Brazil launched a joint initiative aimed at establishing the sector's first comprehensive self-regulation program. The Telecommunications Self-Regulation System (*Sistema de Autorregulação das Telecomunicações*), or the SART, sets common rules and procedures that must be followed by all participating companies in relation to the most relevant topics regarding the relationship between providers and customers, such as telemarketing, offers, billing and customer care.

Although the initiative is still restricted to large operators, the SART will be open to any telecommunications company that wants to participate and commits itself to the principles defined by the program. The main benefit for participating companies are the defined procedures and rules towards improving services, resulting in greater consumer satisfaction and promoting an environment that stimulates a more principle-oriented approach to regulatory issues. However, to avoid conflicts with existing ANATEL regulations, ANATEL's General Regulation on the Rights of Telecommunications Service Consumers (*Regulamento Geral de Direitos do Consumidor de Serviços de Telecomunicações*), currently under revision by ANATEL, will have to be amended in order to make it more principles-oriented and less operational.

The first self-regulatory norm established by SART was the Telemarketing Code of Conduct, which brings self-regulation rules for the relationship between consumers and telecommunication operators, setting forth basic principles that must be followed by the companies, such as the duration and number of calls. Additionally, the Do not Disturb Platform was also created, which has already blocked more than 7 million telephones for telemarketing calls at the customer's request, according to the Telecommunications Providers Association, or CONEXIS.

SART also created the Customer Service Regulation, which sets out rules for meeting consumer demands related to telecommunications products and services, in the various relationship channels available. The Billing Regulation, another initiative coordinated by SART, guides collection actions and establishes commitments on payment methods, debt negotiation, contestation, return of amounts and contractual termination. Finally, the Product Offers Regulation, in turn, bring rules on contracting products and services and their presentation, using simple, direct and easy-to-understand language, focusing on bringing more transparency to information disclosure for consumers. Together, these initiatives emphasize the values of respecting consumer rights, promoting fair competition and encouraging correct, efficient and transparent communication with society in general.

***Roaming Agreements with Iranian Operators***

Some subsidiaries of our controlling shareholder, Telefónica, including us, have entered into roaming agreements with Iranian telecommunication companies. Pursuant to such roaming agreements these subsidiaries' customers are able to roam in the particular Iranian network (outbound roaming) and customers of such Iranian operators are able to roam in the network of Telefónica's relevant subsidiary (inbound roaming). For outbound roaming, these subsidiaries pay the relevant Iranian operator roaming fees for use of its network by Telefónica group customers, and for inbound roaming, the Iranian operator pays the relevant subsidiary roaming fees for use of the respective network by its customers.

Regarding Iran, we have a roaming agreement with MTN Irancell, or Irancell. During 2022, we recorded US$559.37 in roaming revenues and US$0 (zero) of expenses payable to Irancell under this agreement.

Telefónica's subsidiaries, other than our Company (which arrangements are described above), were party to the following roaming agreements with Iranian telecommunication companies in 2021:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) *Telefónica Móviles España S.A.*, or TME *,* Telefónica's Spanish directly wholly-owned subsidiary, has respective roaming agreements with (i) Mobile Telecommunication Company of Iran, or MTCI, (ii) Taliya Mobile, or Taliya, and (iii)

[**Table of Contents**](#TOC)

Telecommunication Kish Co., or TKC. During 2022, TME recorded the following revenues related to these roaming agreements: (i) 56,994 euros from MTCI, (ii) no revenues from Taliya and (iii) no revenues from TKC.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) *Telefónica Germany GmbH & Co. OHG*, or TG, **  Telefónica's German 70.5% indirectly-owned subsidiary, has respective roaming agreements with MTCI and Irancell. During 2022, TG recorded the following revenues related to these roaming agreements: (i) no revenues from MTCI and (ii) 5,685 euros from Irancell.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) *Telefónica UK Ltd*, **  or TUK, Telefónica's former English directly wholly-owned subsidiary, has a roaming agreement with Taliya. TUK ceased to be Telefónica's subsidiary upon the establishment of JV VMED O2 UK on June 1, 2021, to which it was contributed. During 2022, TUK recorded no revenues from Taliya.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) *Pegaso PCS S.A. de C.V.*, or PCS, Telefónica's Mexican directly wholly-owned subsidiary, has a roaming agreement with Irancell. During 2022, PCS recorded 185.30 euros in roaming revenues from Irancell under this agreement.

The net profit recorded by Telefónica's subsidiaries pursuant to these agreements and arrangements did not exceed the related revenues recorded thereunder.

The purpose of all of these agreements is to provide the Telefónica group's customers with coverage in areas where the group does not own networks. For this purpose, Telefónica's subsidiaries intend to continue maintaining those agreements, which are still outstanding.

The Telefónica group does not currently have any forthcoming plans to enter into new roaming arrangements with Iranian telecommunication companies. However, the Telefónica group may consider entering into such arrangements in the future.

&nbsp;&nbsp;&nbsp;&nbsp;D. **Property, Plant and Equipment** 

On December 31, 2022, we had fixed and mobile operations in 2,652 properties, 1,403 of which we own, of which 105 are administrative buildings. Besides that, we have entered into standard leasing agreements to rent the remaining properties, under which 128 administrative areas, five kiosks and 247 retail stores are leased.

Our main physical properties for providing fixed-line telephone services involve the segments of switching (public switching telephone network, or PSTN), transmission (optic and wireless systems), data communication (multiplex devices, IP network), infrastructure (energy systems and air conditioning) and external network (fiber optic and metallic cables), which are distributed in many buildings throughout the state of São Paulo and in the main cities outside the state of São Paulo. Some of these buildings are also used for administrative and commercial operations.

Our main physical property for mobile services consists of transmission equipment, switching equipment, base stations, and other communication devices, such as voicemail, prepaid service, short message service, home location registers, signaling transfer point, packet data switching network and gateways. All switches, cellular sites, administrative buildings, administrative facilities, warehouses and stores are insured against damages for operational risks.

Pursuant to Brazilian legal proceedings, liens have been attached to several properties pending the outcome of various legal proceedings to which we are a party. See "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal Proceedings." In addition, certain of our properties are still pending the applicable licenses and approvals from the local fire departments.

We are constantly making improvements to our facilities and network to meet customer demand and to improve the level of services we offer our clients.

#### Environmental matters
Brazilian federal, state and municipal legislations govern the protection of the environment, the appropriate use of natural resources, fauna and flora preservation and pollution prevention and control. Under these laws, certain environmental licenses must be ensured prior to the construction, installation, expansion and operation of facilities, including those related to radio/cell base stations, antennas, transmission backhaul and backbone networks. In addition to environmental licensing, other environmental regulations may affect our operations, such as, among other matters, regulations related to air emissions, soil and water pollutants, take-back systems,

[**Table of Contents**](#TOC)

recycling and waste management, interference with areas of cultural and historical relevance, environmental protected areas and contamination.

In Brazil, violating environmental rules or regulations may result in civil, administrative or criminal liability. With respect to civil liability, Brazilian environmental laws adopt a standard of strict, unlimited and joint liability in determining the obligation to remediate impacts caused to the environment. In addition, Brazilian courts may pierce the corporate veil when and if it poses an obstacle to the full recovery of environmental damages. In the administrative sphere, a company can be fined up to R$50 million, have its operations suspended, be barred from entering into certain types of government contracts, be required to repair or provide indemnification in respect of any caused environmental liability, lose tax benefits and incentives and be at a competitive disadvantage to match the criteria assessed by global sustainability indexes such as the Dow Jones Sustainability Index and the B3's Corporate Sustainability Index (ISE), among others.

We have a series of procedures in place to protect our networks, our reputation and operations from environmental impacts that goes from operation controls to specific insurance coverage relating to civil and environmental matters. In order to maintain and enhance environmental performance, we have implemented the Solid Waste Management System (Gretel) that allows us to manage the flow of generation, transportation and destination of hazardous and non-hazardous waste, promoting supply chain traceability and circular economy actions. In 51 cities, we have a certified Environmental Management System (EMS) that meets ISO 14,001 requirements since 2016 and goes through an annual audit plan to assess its effectiveness. Several measures are implemented periodically, such as construction to reduce the visual impact of the facilities, modernization of equipment to reduce noise emissions and adaptation of structures in order to contain possible leakages. We also monitor the radiofrequency energy levels transmitted by our antennas, in accordance with current legislation.

The energy consumption of our network infrastructure is very high and to address this challenge we have established a Renewable Energy Plan that allowed us to achieve 100% of renewable electricity by the end of 2018, considering different mixes between the following solutions: distributed generation, free-market (FM) and the purchase of renewable energy certificates with guarantees of origin. In 2022, we achieved 48 Distributed Generation plants in operation in all regions of Brazil. At the end of the project, power generation in this modality will meet 90% of our low-voltage energy consumption, with a total of 85 plants from renewable sources (solar, hydro and biogas).

Since we set our first energy and climate change goals, we have managed to reduce 88% of our GHG emissions (scopes 1 and 2), compared to our emissions as of December 31, 2015, and achieved zero Scope 2 emissions on the market-based approach. In 2020, we became the first telco in Latin America to announce the achievement of carbon neutrality (scopes 1 and 2) by combining renewable energy and carbon credits that generate positive social and environmental impacts while preventing deforestation in parts of the Amazon forest.

In addition to these goals, which are linked to 5% of all of our employees' bonus calculation, we are also looking for ways to reduce our impact beyond our borders. Considering the importance and weight that our suppliers have for us, we structured a program called the Carbon in the Supply Chain Program to engage them in the topic. We invited to part of our suppliers to participate and held a series of meetings and webinars to discuss the topic of climate change. The program's objective is to encourage suppliers to measure and manage their emissions, seeking alternatives to reduce them and innovate via a voluntary commitment, thus contributing to our Scope 3 reduction target.

Environmental transparency is an important step towards a net-zero and positive future for nature. Our commitment to the best governance practices and initiatives that mobilize our decarbonization journey was recognized by CDP (Carbon Disclosure Project). In 2022, we were among the three Brazilian companies that received the maximum score "A" for their leadership in corporate transparency and action on climate change (Climate Change A-List), demonstrating the strength of our environmental commitment.

In 2006, a few years in advance of the Solid Waste National Policy launch (Law No. 12,305/2010), we were the first telecommunications company in Brazil to offer collection points at all of our stores for old mobile phones, accessories and batteries, where customers and other individuals can dispose of their used equipment ensuring proper disposal of these materials. In the fixed-line telecom business, we offer the option of home collection or store return of the equipment in case of disconnection due to default or the end of the contract. These materials undergo triage and can be refurbished to be used again with full technical capacity and layout conditions. These processes ensure that almost all the collected electronic waste is recycled or reused.

#### Item 4A. Unresolved Staff Comments
None.

#### Item 5. Operating and Financial Review and Prospects
**A.**Operating Results

The following discussion should be read in conjunction with our consolidated financial statements and accompanying notes and other information appearing elsewhere in this annual report. We prepared our consolidated financial statements included in this annual report in accordance with IFRS.

**Overview**

Our results of operations are principally affected by the following key factors.

***Effects of the COVID-19 Pandemic***

The COVID-19 pandemic has created significant volatility, uncertainty, and economic disruption. We continue to closely monitor the evolution of the COVID-19 pandemic in Brazil and globally, in order to take preventive measures to minimize the spread of the virus, ensure the continuity of operations and safeguard the health and safety of our personnel. Based on the information available as of the date of this annual report, we present below a summary of the main effects of the COVID-19 pandemic on our business and results of operations:

● Our stores faced little to no restrictions in their operations in 2022, as the number of COVID-19 cases fell and vaccination rates rose in Brazil, removing limitations we had during 2020 and 2021;

● The impact on revenues was also of little relevance, not only because of the macroeconomic recovery, but also due to the increased perceived relevance of connectivity, which became of absolute essentiality, yielding increased data consumption and higher sensitivity to network quality. Accordingly, our mobile accesses increased by 14.1 million, also helped by the acquisition of Oi Móvel's assets, reaching an all-time high of 98.0 million, while our FTTH additions in the period reached 874 thousand, taking our FTTH subscriber base to 5.5 million for the year ended December 31, 2022;

● Costs related to sales, such as sales commissioning and advertising, continue to be positively impacted by the increased digitalization initiatives and automation of customer care; and

● Due to the aforementioned increased demand for telecommunication services, efficient financial management and despite the macroeconomic downturn, our level of bad debts fell by 8.4%.

Our results continued to recover throughout 2022 from the relatively mild impacts of the COVID-19 pandemic experienced in 2020 and 2021. Since the beginning of the governmental restrictive measures, the value of connectivity increased for society as a whole, which was accordingly reflected in our top line and results. We reached an all-time high in the number of accesses, 112 million, with 98 million on mobile (another record) and 14 million on fixed-line services. This represented a significant 14.1 million mobile net additions, with mobile churn stable vs 2021 at 2.8% in 2022, and 874 thousand net additions in FTTH. As a result, our fixed revenues experienced the first yearly growth since 2015, growing 2.1% year-over-year given our fast fiber deployment, which remained at full-speed, and double-digit B2B growth as companies resumed their investments. In 2022, our net revenues reached R$48.0 billion, growing 9.1%, with Mobile Service Revenues expanding 12.1%, adding to the abovementioned growth of fixed-line services.

Given that Vivo is the gateway for the digital space both for B2C and B2B customers, we are focusing our efforts to become a one-stop shop regarding connectivity, offering all goods and services related to the digital space. This impacts our revenue composition, as we continue to expand the sale of handsets and digital services, which have lower margins than telco services. As a

[**Table of Contents**](#TOC)

result, our cost base is shifting accordingly, with costs of services and goods sold growing 10.7%, while costs of operations expanded by 15.2%, on higher personnel expenses.

However, the full impact of the COVID-19 pandemic on our business, financial condition, and results of operations will depend on numerous evolving factors that we may not be able to accurately predict and that will vary by market, including the duration and scope of the pandemic, the impact of the pandemic on economic activity, and actions taken by governments, businesses, and individuals in response. See also "Item 3. Key Information—D. Risk Factors— Risks Relating to the Brazilian Telecommunications Industry and Us—Our business, operations and results have been, and may continue to be, adversely impacted by the effects of the COVID-19 pandemic."

#### Brazilian economic environment
The Brazilian economic activity continued to surprise positively during 2022, surpassing its pre-pandemic level. The end of social distance measures benefited the services sector and labor market, and higher income transfers supported consumption. In this context of stronger demand, consumer inflation remained above its target, despite its relevant slowdown since 2H22. In this sense, the Central Bank kept the monetary policy tightening until August 2022, when started to indicate that the Selic rate will be maintained at the current level of 13.75% for a long period amid increasing inflation expectations and growing fiscal uncertainties due to modifications in the spending cap rule to allow higher public expenditures from 2023. Against this backdrop, local asset prices have become more volatile, also reflecting the uncertain global outlook due to the high inflation, increasing interest rates and economic activity slowdown.

The Brazilian economy experienced a relatively low rate of growth throughout the last decade, amid economic crises. Despite that, according to market data, the Brazilian GDP rose 3.0% in 2022, after a 5.0% increase in 2021. In previous years, according to IBGE, the GDP dropped 3.3% in 2020 due to the Covid-19 pandemic, advancing 1.2% in 2019, 1.8% in 2018 and 1.3% in 2017.

Consumer prices, as measured by the IPCA, increased 5.8% in 2022, once more above the target interval established by the Central Bank of 3.5% +/- 1.5%. In 2021, 2020 and 2019 the IPCA inflation stood at 10.1%, 4.5% and 4.3%, in that order. Inflation, as measured by the IGP-DI, which includes wholesale, retail and home-building prices, rose 5.0% in 2022, compared to 17.7%, 23.1% and 7.7% in 2021, 2020 and 2019, respectively. As the inflation rate measured by IPCA surpassed the target band, the Copom raised the Selic rate from 9.25% as of December 31, 2021 to 13.75% as of December 31, 2022.

Brazil registered a trade balance surplus of US$62.3 billion in 2022, slightly above the positive result of US$61.2 billion registered in 2021. Exports rose 19.3%, posting US$335.0 billion, while imports advanced 24.3%, to US$272.7 billion. Foreign direct investment inflows into Brazil increased to US$77.1 billion in 12 months accumulated until November 2022, compared to US$46.4 billion in 2021. International reserves as of November 30, 2021 were US$331.5 billion, compared to US$362 billion as of December 31, 2020.

The public sector fiscal deficit continued to fall in 2022, mainly due to the public revenues increase reflecting the economic activity growth. The primary fiscal result reached a surplus of 1.8% of the GDP as of November 30, 2022, compared to a positive result of 0.7% of the GDP as of December 31, 2021. As a consequence, gross public debt fell from 80.3% of GDP in 2021 to 74.5% in November 2022. In this context, J.P. Morgan Emerging Markets Bond Index Plus (EMBI + Brazil), which tracks total returns for traded external debt instruments in emerging markets, decreased to 256 basis points by the end of 2022, from 326 and 260 basis points at the end of 2021 and 2020, respectively. The rising uncertainties regarding fiscal and debt sustainability amid higher pressures for more expenditure, spending cap waiver for 2023 and lack of reforms during 2022 implied higher asset price volatility in that period.

The real appreciated against the U.S. dollar in 2021 by 5.12%. The exchange rate as of December 31, 2022 was R$5.286 per US$1.00, from R$5.571 per US$1.00 as of December 31, 2021.

Our business is directly affected by the external environment and the Brazilian economy. Higher volatility of the Brazilian real against the U.S. dollar may affect the purchasing power of Brazilian consumers and cause a negative impact on the ability of our customers to pay for our telecommunications services.

[**Table of Contents**](#TOC)

#### Impact of inflation on our results of operations
Before 2006, the fees we charged our customers were periodically adjusted by ANATEL based on the inflation rates measured by the IGP-DI.

Starting in 2006, telephone fees were indexed to the IST, which is a basket of Brazilian indexes that reflect the telecommunications sector's operating costs. Such indexing reduced inconsistencies between revenue and costs in our industry and therefore reduced the adverse effects of inflation on our business. The IST for the year ended November 30, 2022 was 6.91% according to the most recent ANATEL data.

The table below shows the Brazilian general price inflation (according to the IGP-DI, IPCA and the IST) for 2018 through 2022:

***Market Conditions and Geopolitical Environment***

The general business environment in which we operate was relatively volatile in 2022, a trend we expect to continue in 2023, driven by, among other factors, inflation and global supply chain disruptions resulting primarily from the COVID-19 pandemic, recent geopolitical developments and economic conditions in Brazil. However, we experienced a limited impact from supply chain issues during 2022 compared to 2021, primarily because of a normalization in the provision of smartphones and network equipment by our key vendors in comparison to the prior year.

Regarding inflation, during 2022 our cost base was impacted by inflation when compared to 2021, which mainly affected personnel and third-party services costs. On the other hand, we have generally been able to pass through price increases, mostly in line with inflation, to our customer base, partially offsetting the negative effects.

Although we are not able at this time to predict the extent to which these events may have a material, or any, effect on our financial or operational results in future periods, we could be negatively impacted if economic conditions decline further and remain volatile.

***Geopolitical Developments***

Russia's invasion of Ukraine in February 2022, and the resulting conflict between Russia and Ukraine, led to disruptions in the global markets for various commodities, particularly fuel, certain crop commodities and fertilizers. Many Western countries have adopted sanctions on a number of Russian and/or Belarussian companies and individuals, including persons affiliated with Russian and/or Belarussian government leadership, and have also restricted trade in various commodities, including fertilizers, causing changes in global trade flows as both manufacturers and customers react to the changing regulatory landscape.

While the precise effect of the ongoing war and these sanctions on the Russian and global economies remains uncertain, they have already resulted in significant volatility in financial markets, depreciation of the Russian ruble and the Ukrainian hryvnia against the U.S. dollar and other major currencies, as well as an increase in energy and commodity prices globally. Should the conflict continue to increase, markets may face continued volatility as well as economic and security consequences including, but not limited to, supply shortages of different kinds, further increases in prices of commodities, including piped natural gas, oil and agricultural goods, among others.

While as of the date of this annual report there have not been any material impacts from the ongoing war between Russia and Ukraine on our business, we are continuously monitoring the developments to assess any potential future impacts that may arise as a result of

[**Table of Contents**](#TOC)

the ongoing war. The adverse effects—global or localized—of the ongoing war between Russia and Ukraine, and/or economic sanctions and import and/or export controls to be imposed by the United States, the UK, the EU or others, and their adverse effects on the wider global economy and market conditions could have a material adverse effect on our business, financial condition and results of operations.

**Results of Operations for the Year Ended December 31, 2022, Compared to the Year Ended December 31, 2021**

***Gross operating revenue***

Our gross operating revenue increased by 4.9% to R$67,761.0 million in 2022 from R$64,611.5 million in 2021. Service revenue increased by 4.4% to R$60,845.2 million in 2022 from R$58,263.5 million in 2021, mainly due to the incorporation of Oi Móvel's (Garliava) assets, which drove our Mobile performance up, and to the positive performance of the other services that compose, together with Mobile, our Core revenues, such as FTTH, IPTV and Corporate Data & ICT. Sale of goods revenue increased by 8.9% to R$6,915.9 million in 2022 from R$6,348.1 million in 2021, boosted by the sale of 5G smartphones and by the broad range of accessories being sold in our stores.

&nbsp;&nbsp;&nbsp;&nbsp;(1) These include telephone services, use of interconnection network, data and SVA services, cable TV and other services.

&nbsp;&nbsp;&nbsp;&nbsp;(2) These include sale of goods (handsets, sim cards and accessories) and *Vivo Tech* equipment.

&nbsp;&nbsp;&nbsp;&nbsp;(3) In July 2022, Complementary Law No. 194/2022, which addresses taxes levied in sectors deemed to be essential and indispensable for goods and services, was issued resulting in the reduction of ICMS rate on communications services (Note 20).

***Net operating revenue***

Net operating revenue increased by 9.1% to R$48,041.2 million in 2022 from R$44,032.6 million in 2021, as both the revenues of Services and Goods Sold grew above the inflation rates registered in the period (IPCA of 5.8% in 2022), expanding 8.9% and 11.5% when compared to 2021, respectively. Our Services revenue benefitted, in 2022, from the acquisition of Oi Móvel's (Garliava) assets, which brought us an additional 12.5 million mobile accesses and increased our net operating revenue by R$1,117.2 million, thus adding to the strong performance of our organic mobile business. In addition, our fixed revenues grew on a yearly basis for the first time since 2015. The positive performance was driven by the continued evolution of revenues coming from the sale of FTTH broadband and Corporate Data & ICT. Regarding the revenues from Goods Sold, the performance was mainly impacted by the increased demand for 5G smartphones, as we started to deploy the technology over the Brazilian main cities during 2022, thus leading to higher sales of handsets.

***Cost of sales***

Cost of sales increased by R$2,088.3 million, or 9.2%, to R$27,431.6 million in 2022 from R$24,781.4 million in 2021. The table and descriptions below set forth explanations for these variations:

*Cost of Goods Sold:* Cost of goods sold increased by R$619.0 million, or 19.2%, to R$3,841.1 million in 2022 from R$3,222.0 million in 2021, mainly due to the increased sale of handsets and ICT equipment, that led to an acceleration of the Sale of Goods revenue line.

*Depreciation and Amortization:* Costs related to depreciation and amortization increased by R$620.8 million, or 6.4%, to R$10,309.6 million in 2022 from R$9,688.8 million in 2021, resulting from the investment related to the initial deployment of our 5G network, which also led to higher amortization costs related to the 5G spectrum licenses, and to the increased investment made to expand our 4.5G network and FTTH deployment, as well as to an increase of leasing contracts.

*Outside Services and Other:* Costs related to outside services and other increased by R$807.9 million, or 11.7%, to R$7,733.3 million in 2022 from R$6,914.5 million in 2021, primarily due to costs related to third-party licenses and services, associated with the expansion of our Corporate Data & ICT revenue.

*Interconnection and Network Use:* Costs related to interconnection and network use decreased by R$59.3 million, or 4.9%, to R$1,142.7 million in 2022, from R$1,202.0 million in 2021, primarily as a result of the lower interconnection costs, due to tariff adjustments in the period.

*Rental, Insurance, Condominium and Connection Means:* Costs related to rent, insurance, condominium and connection means increased by R$120.0 million, or 10.1%, to R$1,307.9 million in 2022, from R$1,188.0 million in 2021 due to higher costs related to the rental of passive network infrastructure, such as towers and poles.

*Personnel:* Personnel expenses increased by R$247.2 million, or 28.7%, to R$1,109.1 million in 2022 from R$861.9 million in 2021, driven by the annual wage and benefits readjustments and higher costs with variable compensation, as well as to the acquisition of Vita IT made during the year, that led us to incorporate its staff.

*Taxes, Charges and Contributions:* Taxes, charges and contributions remained relatively stable, increasing R$201.3 million, or 11.8%, to R$1,905.6 million in 2022, from R$1,704.2 million in 2021, primarily due to higher regulatory fees arising from the positive evolution of the mobile customer base.

***Operating (expenses) income***

Operating (expenses) income increased by R$1,705.4 million, or 13.9%, to R$13,987.8 million in 2022, from R$12,282.4 million in 2021. The table and descriptions below set forth explanations for these variations:

---

*Selling Expenses:* Our selling expenses increased by R$245.0 million, or 2.1%, to R$11,839.1 million in 2022 from R$11,594.1 million in 2021, mainly due to the 15.0% increase in personnel-related expenditures, to R$3,060.0 million, resulting from the annual wage and benefits readjustments and higher costs with variable compensation. The increase in personnel fully compensated savings unlocked by the growing digitalization and automation of customer service processes such as back-office, billing and posting, led by the increasing adoption of our digital self-service app Meu Vivo, as well as by the reduction of our provision for doubtful accounts, which decreased 8.4% in 2022 to R$1,315.6 million.

*General and Administrative Expenses:* Our general and administrative expenses increased by R$121.7 million, or 4.7%, to R$2,737.6 million in 2022 from R$2,615.9 million in 2021, mainly due to the 22.3% increase in personnel-related expenditures, to R$719.0 million, resulting from the annual wage and benefits readjustments and higher costs with variable compensation, as well as to greater expenses with systems development, licenses and software, and judicial consultancy firms.

[**Table of Contents**](#TOC)

*Other Operating Income (Expenses),* Net: Other operating income, net decreased by R$1,338.7 million, or 69.5%, to an income of R$588.9 million in 2022 from R$1,927.6 million in 2021, mainly due to the extraordinary positive results registered in 2021 related to a net income of R$416.6 million from the FiBrasil operation and a higher level of tax recoveries versus 2022.

*Financial income (expenses), net*

For the year ended December 31, 2022, financial expense, net reached R$1,766.3 million, an increase of R$639.7 million, from an expense of R$1,126.6 million for the year ended December 31, 2021. The increase was mainly due to higher average indebtedness arising from leasing contracts and debentures issuance, coupled with the impact of a rise in the average SELIC rate in the period.

*Income and social contribution taxes*

We recorded an expense from income and social contribution taxes in the amount of R$773.7 million in 2022, compared to an income of R$269.8 million in 2021, an increase of R$1,043.5 million, mainly due to an extraordinary effect registered in 2021, related to the recognition of a tax credit in the amount of R$1,407.5 million relative to a decision of the Brazilian Federal Supreme Court holding that the levy of IRPJ and CSLL on SELIC rate corrections was unconstitutional. During 2022, our effective rate of income and social contribution taxes reached 16.0%.

**Results of Operations for the Year Ended December 31, 2021, Compared to the Year Ended December 31, 2020**

For a discussion of our results of operations for the year ended December 31, 2021 compared to the year ended December 31, 2020, please see "Item 5. Operating and Financial Review and Prospects—A. Operating Results—Results of Operations for the Year Ended December 31, 2021 Compared to the Year Ended December 31, 2020" of our annual report on Form 20-F for the year ended December 31, 2021.

**B.** Liquidity and Capital Resources

***General***

We fund our operations and capital expenditures primarily from operating cash flows, loans obtained from financial institutions or development banks, and debentures. As of December 31, 2022, we had R$2.3 billion in cash and cash equivalents. We do not have any material unused sources of liquidity.Our principal cash requirements include:

● the servicing of our indebtedness;

● capital expenditures; and

● the payment of dividends.

In 2022, we expended cash on hand to pay the licenses and cash obligations related to the acquisition of 5G spectrum and the consideration due by us under the Oi Agreement upon the consummation of the transactions contemplated thereby.

Our management believes that our sources of liquidity and capital resources, including working capital, are adequate for our present requirements.

***Sources of Funds***

Our cash flow from operations was R$18.9 billion in 2022, an increase of 4.8% over the R$18.1 billion in 2021. The increase in cash flow from operations is primarily due to a rises of taxes to recover, which are mainly a result of certain tax credits and taxes, charges and contributions, partially offset by interest paid on loans, financing, debentures, leases, 5G licenses and liabilities for the acquisition of a company and income tax and social contribution paid.

[**Table of Contents**](#TOC)

For a discussion of our sources of funds for the year ended December 31, 2021 compared to the year ended December 31, 2020, please see "Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Sources of Funds" of our annual report on Form 20-F for the year ended December 31, 2021.

***Uses of Funds***

Our cash flow used in investing activities was R$14.2 billion in 2022, against R$8.1 billion in 2021. The variation in the cash flow used in investment activities is mainly due to payment for acquisition of investments and capital contribution in subsidiary.

Our cash flow used in financing activities recorded an outflow of R$8.9 billion in 2022, compared to an outflow of R$9.3 billion in 2021. The decrease in cash flow used in financing activities of R$0.4 billion in 2022 compared to 2021 was mainly due to lower payment of financing, debentures and leases, partially offset by income from loans and debentures.

For a discussion of our uses of funds for the year ended December 31, 2021 compared to the year ended December 31, 2020, please see "Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Uses of Funds" of our annual report on Form 20-F for the year ended December 31, 2021.

***Indebtedness***

As of December 31, 2022, our total debt was as follows:

| &nbsp;&nbsp;Noncurrent |  |  |  | 13281.9 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Our finance leases are related to towers and rooftops, IT equipment leases, infrastructure rent and other means of transmission.

Interest and principal payments on our indebtedness as of December 31, 2022 due in 2023 and 2024 total R$6,019.9 million and R$3,145.6 million, respectively.

The agreements governing most of our outstanding loans and financing contain certain standard restrictive covenants, including financial covenants. These agreements can provide an acceleration of the full balance of our obligations in the event of default. In general, such agreements are subject to the acceleration of maturity over: (i) the inclusion in the agreement of our shareholders, bylaws or articles of incorporation or of the companies that control us of conditions that lead to restrictions or loss of ability to pay financial obligations arising from these agreements; (ii) a conviction or final judgment against us in relation to child labor, slave labor or environmental crime; or (iii) liquidation, dissolution, insolvency; bankruptcy, judicial or extrajudicial recovery to any creditor or class of creditors.As of December 31, 2022, we were not in default of any of our obligations and therefore none of our liabilities were subject to acceleration.

[**Table of Contents**](#TOC)

***Foreign exchange and interest rate exposure***

We face foreign exchange risk due to our foreign currency-denominated accounts payable (including our capital expenditures, particularly equipment) and receivables in foreign currency. A devaluation of the *real* may increase our cost of debt and certain commitments in a foreign currency. Our revenue is earned in *reais*, and we have no material foreign currency-denominated assets, except income from hedging transactions, interconnection of international long-distance services and services rendered to customers outside Brazil. Equity investments in foreign companies also suffer effects with variations in the exchange rate.

We use derivative instruments to limit our exposure to exchange rate risk. Since September 1999, we have hedged all of our foreign currency-denominated bank debt using swaps and other derivative instruments. Since May 2010, the company began using net balance coverage, which is the hedging of net positions in foreign exchange exposures, or assets (issued invoices) *minus* liabilities (received invoices) for foreign exchange exposures, substantially reducing our risk to fluctuations in exchange rates. We could continue to face exchange rate exposure with respect to our planned capital expenditures, however, as a small part of our planned capital expenditures are denominated or indexed in foreign currencies (mostly U.S. dollars). We systematically monitor the amounts and time of exposure to exchange rate fluctuations and may hedge positions when deemed appropriate.

The largest part of our *reais*-denominated debt originally pays interest as a percentage of the CDI Rate or has been swapped to do so. The CDI Rate is indexed to the average rate of operations transacted among the banks within Brazil. With the CDI Rate being a floating rate, we remain exposed to market risk. This exposure to the CDI Rate is also present in long derivatives positions and financial investments, which are indexed to percentages of the CDI Rate.

For more information, see "Item 11. Quantitative and Qualitative Disclosures about Market Risk."

***Tabular Disclosure of Contractual Obligations***

**Capital Expenditures and Payment of Dividends**

Our principal capital requirements are for capital expenditures and payments of dividends to shareholders. Capital expenditures consisted of additions to property, plant and equipment and additions to intangible assets, including licenses which totaled R$9.7 billion, R$13.2 billion and R$8.0 billion for the years ended December 31, 2022, 2021 and 2020, respectively. These expenditures relate primarily to the expansion of our network.

We may seek financing for part of our capital expenditures and cash management assistance from the Brazilian government, in particular from BNDES, which is the main government financing agent in Brazil, as well as from the local or foreign capital markets or from local and foreign financial institutions. See "Item 4. Information on the Company—A. History and Development of the Company—Capital Expenditures."

Pursuant to our bylaws and Brazilian Corporate Law, we are required to distribute a mandatory minimum dividend of 25% of our "adjusted net income" (as defined below) in respect of each fiscal year to the extent earnings are available for distribution.

Adjusted net income, as determined by Brazilian Corporate Law, is an amount equal to our net income adjusted to reflect allocations to or from (i) legal reserve, (ii) bylaw reserve and (iii) a contingency reserve for anticipated losses, if any.

We may also make additional distributions to the extent that we have profits and reserves available to distribute. All of the above distributions may be made as dividends or as tax-deductible interest on shareholders' equity. Interest on shareholders' equity is tax-deductible payments pursuant to Brazilian Corporate law, that a company may make, in addition to dividends, which the company may treat as financial expenses for tax and social contribution purposes. For more information on the payment of interests on shareholders' equity, see "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Dividends and Dividend Distribution Policy—Dividends and Interest on Shareholders' Equity." We deliberated in favor of the distribution of dividends and interest on shareholders' equity of R$3.5 billion, R$5.8 billion and R$5.4 billion in 2022, 2021 and 2020, respectively.

Our management expects to meet 2023 capital requirements primarily from cash provided from our operations. Net cash provided by operations was R$18.9 billion, R$18.1 billion and R$19.3 billion in 2022, 2021 and 2020, respectively.

Adjustments to net income for purposes of calculating the basis for dividends include allocations to various reserves that effectively reduce the amount available for the payment of dividends. For the fiscal year ended December 31, 2022, in addition to the interim dividend and interest on own capital payments made in 2022, management decided to propose an additional proposed dividend to shareholders in the amount of R$827 million. The proposal to pay dividends will be approved at the shareholders' meeting that will approve the 2022 annual report. See "Item 3. Key Information—D. Risk Factors—Risks Relating to the Common Shares and the ADSs— Holders of our ADSs are not entitled to attend shareholders' meetings and may only vote through the depositary." and "Item 10. Additional Information—B. Memorandum and Articles of Association—Description of Our Bylaws—Voting Rights."

**In January 2020, the IASB issued amendments to IAS 1 in order to specify the requirements for classifying liabilities as current or non-current. The amendments clarify: (i) what a right to postpone settlement means; (ii) that the right to defer must exist on the reporting date; (iii) that this classification is not affected by the likelihood that an entity will exercise its right of postponement; and (iv) that only if a derivative embedded in a convertible liability is itself an equity instrument, the terms of a liability would not affect its classification. Changes are effective for periods beginning January 1, 2023 and must be applied retrospectively.**

#### Amendments to IAS 8: Definition of accounting estimates
**In February 2021, the IASB issued amendments to IAS 8, which introduces the definition of "accounting estimates". The amendments clarify the distinction between changes in accounting estimates and changes in accounting policies and correction of errors. In addition, they clarify how entities use measurement and input techniques to develop accounting estimates. The changes will be effective for periods beginning on or after January 1, 2023 and will apply to changes in accounting policies and estimates that occur on or after the beginning of that period.**

#### Amendments to IAS 1 and IFRS Practice Statement 2: Disclosure of Accounting Policies
**In February 2021, the IASB issued amendments to IAS 1 and IFRS Practice Statement 2 Making Materiality Judgments, which provides guides and examples to help entities apply materiality judgment for the disclosure of accounting policies. The changes are to help entities disclose accounting policies that are more useful by replacing the requirement for disclosure of significant accounting policies for material accounting policies and adding guides to how entities should apply the concept of materiality to make decisions about policy disclosure accounting.**

**The amendments to IAS 1 are applicable for periods beginning on or after January 1, 2023 with earlier adoption permitted. Since the amendments to Practice Statement 2 Making Materiality Judgments provide non-mandatory guidance in applying the material definition to accounting policy information, an adoption date for this amendment is not required.**

**D.** Trend Information

**In 2022, Brazilian macroeconomics presented recovering figures from the pandemic, with the improvement of sanitary conditions still playing an important role in driving consumer growth, also strengthened by developments in the labor market, particularly in tourism and in the service sector.**

**Reliable high-speed connectivity will continue to gain relevance as consumers become more mature in their digital habits and organizations make progress in their digitalization journeys. We expect growth in the number of professionals providing remote services and an increase in devices connected to the internet. In addition, we believe that Brazilian society continues to follow a trend to become more selective with its brands, challenging corporations to adopt an ESG-conscious agenda.**

[**Table of Contents**](#TOC)

**The higher cost of capital caused by rising interest rates has reduced access to capital in the broadband market, especially for small ISPs. The pressure for stronger returns on investment will likely accelerate market consolidation in the short term. On the other hand, the demand for ultra-broadband connectivity will continue to increase, generating space for new business models based on efficiency, such as neutral networks.**

**Brazilian main operators launched 5G in all capital cities and Vivo will continue to work on 5G coverage expansion, bringing the best speed and quality across the country to our customers and investing in 4.5G network capacity whenever needed, keeping a track record of unmatched user experience in mobile.**

**Increased online interactions have created chances for value creation in the digitalization process of traditional sectors like education and health services as well as in continuous developments of more digitalized domains like financial services and media. Furthermore, we believe that more accessible solutions in the business of smart homes and clean energy are also expected to reach more average consumers. Leveraging on new partnerships and counting on the support of open innovation initiatives, Wayra and Vivo Ventures, we will continue our journey towards creating the leading B2C digital ecosystem in Brazil.**

**In B2B, digitization efforts will continue to appear at the top of CEOs agendas, driving demand for better connectivity services and creating more room for Professional & Managed Services in Cloud, Cyber Security, IoT and Big Data.**

**In this context, we believe that we are well positioned to strengthen our leadership and are committed as well to keep serving our fixed and mobile customers with the finest experiences on the market. We expect to maintain the first position in customer satisfaction by continually investing in artificial intelligence and by creating more engaging experiences in our Vivo App.**

**Our strategic pillars #temvivopratudo (*There is a Vivo for everything*), #temtudonavivo (*You can find everything at Vivo*), #DNAvivosomos (*Vivo DNA in everything we are*), #DNAvivofazemos (*Vivo DNA in everything we do*) and #vivosustentabilidade (*Vivo Sustainability*) will allow us to achieve our purpose of advancing digitalization to bring people together (*Digitalizar para Aproximar*).**

**E.** **Critical Accounting Estimates**

The preparation of the financial statements requires the use of certain critical accounting estimates and the exercise of judgment by the Company's Management in applying the Company's accounting policies. These estimates are based on experience, better knowledge, information available at the end of the fiscal year, and other factors, including expectations of future events that are believed to be reasonable in the circumstances. Settlement of transactions involving these estimates may result in values that are different from those recorded in the financial statements due to the criteria inherent in the estimation process. The Company reviews its estimates at least annually.

***Business Combination - Acquisition of part of Oi UPI Mobile Assets***

Pursuant to IFRS 3 (R) - Business Combinations, business acquisitions are accounted for using the acquisition method. The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the fair values of assets transferred and liabilities assumed on the acquisition date from the acquiree's former controlling shareholders and any interests issued in exchange for control of the acquiree. On the date of these consolidated financial statements, the Company had already concluded the report for the allocation of the purchase price (Purchase Price Allocation – PPA), through the analysis of the determination of the fair value of the identifiable assets transferred and the liabilities assumed from Garliava.

The assumptions, critical judgments, methods and hypotheses used by the Company to determine these fair values were as follows:

Licenses

The fair value of the licenses was determined using the discounted cash flow method under the Income Approach, which considers the income-earning capacity of the identified asset or business. The premise for this approach is that the value of an asset or business can be measured as being equivalent to the present value of the net economic benefit (cash receipts minus cash expenses) to be received over its useful life.

[**Table of Contents**](#TOC)

The main assumptions used in the assessment of the licenses were: (i) Revenues: based on the number of existing active customers migrated from Oi to Garliava, as well as the average revenue per user ("ARPU"), considering an estimated loss of annual customers of 9% per year, on average; (ii) Costs and Expenses: were projected in accordance with historical data obtained by the Company and expectations of normalization of the operating margin in the long term. The projections were based on fixed and variable percentages of expenses, adjusting the fixed portion according to inflation and the variable according to revenue; (iii) Oibda Margin: vary between 35.3% in 2022 and 54.5% in 2030. The observed margin gains are due to gains in scale of the operation, improvements in efficiency, operational synergies to be achieved by merging operations of Garliava within the Company; iv) Depreciation: represents an average of 9.2% of net operating revenue; Tax rate: 34%, according to Brazilian tax legislation; and (v) After-tax discount rate: 12.4%.

Customer portfolio

The customer portfolio was valued using the MEEM method ("Multi-period Excess Earnings Method"), which is based on a calculation of discounting cash flows from future economic benefits attributable to the customer base, net of eliminations of the implied contribution obligations. To estimate the remaining useful life of the customer base, an analysis was made of the average duration of customer relationships using a churn rate.

The purpose is to estimate a lifetime curve that predicts future turnover profiles associated with the current customer base. As an approximation for the customer life curve, the so-called "Iowa curves" were considered.

The main assumptions used in assessing the customer portfolio were: (i) Customers: 5 relationships with customers were evaluated, namely: B2C prepaid, B2C postpaid, B2C Control, B2B postpaid and B2B M2M; (ii) Revenue: based on the number of existing customers by type, migrated from Oi to Garliava, as well as the ARPU charged for providing the service. In the revenue projection, an estimate of annual customer loss and ARPU stability were considered; (iii) Churn rate: was calculated based on the historical percentage of customers leaving, ranging from 26.8% to 50.2%; (iv) Costs and expenses: were projected in accordance with historical data obtained by the Company and expectations of normalization of the operating margin in the long term and operating synergies to be realized by the merger of Garliava's operations within the Company. The projections were based on fixed and variable percentages of expenses, adjusting the fixed portion according to inflation and the variable according to revenue, considering an add-back of 97% of marketing expenses, to reflect the exclusion expenses related to obtaining new customers, based on market standards; (v) Tax rate: 34%, pursuant to Brazilian tax legislation; and (v) after-tax discount rate: 12.4%.

Fair Value of Contingent Liabilities

Under IFRS 3(R) Business Combinations, the acquirer recognizes, at the acquisition date, contingent liabilities assumed in a business combination even when it is not probable that an outflow of resources will be required to settle the obligation, provided that it is a present obligation that arises from past events and its fair value can be measured reliably.

***Accounting for long-lived assets***

Property, plant and equipment and intangible assets, other than goodwill, are recorded at acquisition cost. Property, plant and equipment and intangible assets with definite useful lives are depreciated or amortized on a straight-line basis over their estimated useful lives. Intangible assets with indefinite useful lives, including goodwill, are not amortized, but are instead, subject to an impairment test on a yearly basis and whenever there is an indication that such assets may be impaired.

Accounting for long-lived assets and intangible assets involves the use of estimates for determining the fair value at their acquisition dates, particularly for assets acquired in business combinations and for determining the useful lives over which they are to be depreciated or amortized as well as their residual value. Useful lives are assessed annually and changed when necessary to reflect current evaluation on the remaining lives in light of technological change, network investment plans, prospective utilization and physical condition of the assets concerned.

The carrying values and useful lives applied to the principal categories of property, plant and equipment, and intangibles, are disclosed in Notes 13 and 14 to our consolidated financial statements.

***Estimated losses for impairment of accounts receivable***

In determining whether the credit risk of a financial asset has increased significantly since the initial recognition and in estimating the expected credit losses, we consider reasonable and bearable information that is relevant and available. This includes quantitative

[**Table of Contents**](#TOC)

and qualitative information and analysis, based on our historical experience, credit assessment and considering forward-looking information. Although we believe that the assumptions used are reasonable, actual results may be different.

Additional information on estimated losses for impairment of accounts receivable is disclosed in Note 5 to our consolidated financial statements.

***Impairment of nonfinancial assets, including goodwill***

An impairment loss exists when the accounting value of an asset or cash-generating unit exceeds its recoverable amount, which is the higher between the fair value less selling costs and the value in use. The estimated fair value less selling costs is based on the information available from transactions involving the sale of similar assets or the market price less additional costs regarding the disposition of such asset. The value in use is based on the model of discounted cash flow. Cash flows are derived from the budget and do not include activities of reorganization for which the company has not yet been committed or significant future investments that will improve the group of assets of the cash-generating unit subject to the test. The recoverable amount is sensitive to the discount rate used in the method of discounted cash flows as well as to the projected future cash flow and the expected future growth rate used for the purposes of determining terminal value. Furthermore, additional factors, such as technological obsolescence, the suspension of certain services and other circumstantial changes are taken into account.

The carrying value of goodwill and the key assumptions used in performing the annual impairment assessment are disclosed in Note 15 to our consolidated financial statements.

***Provisions for tax, labor, civil and regulatory proceedings***

We record provisions for tax, labor, civil and regulatory claims where an outflow of resources is considered probable and a reasonable estimate can be made of the likely outcome. The assessment of the likelihood of loss includes assessing the available evidence, the hierarchy of laws, the available jurisprudence, the most recent court decisions and its materiality in the legal system as well as the evaluation of the case by external counsels. Provisions are reviewed and adjusted to take into account changes in circumstances such as the applicable prescriptive period, results from tax inspections or additional exposure identified based on newly issued court decisions. A significant change in these circumstances or assumptions could result in a corresponding increase or decrease in the amount of our provisions.

Additional information on provisions for tax, labor, civil and regulatory proceedings is disclosed in Note 20 to our consolidated financial statements.

***Pension and other post-retirement benefit plans***

The cost of defined benefit retirement plans and other post-employment medical care benefits and the present value of pension and other postretirement obligations are determined using actuarial valuation methods. The actuarial valuation methods involve the use of assumptions about discount rates, expected future salary increases, mortality rates, health care costs trend rates and future increases in retirement benefits and pensions. The obligation of a defined benefit is highly sensitive to changes in these assumptions. All assumptions are reviewed at each year-end. The mortality rate is based on mortality tables available in the country. Future increases in wages and retirement benefits and pensions are based on expected future inflation for Brazil. The assumptions reflect the historical experience and our judgment regarding future expectations.

The value of our net pension obligation on December 31, 2022, the key financial assumption used to measure the obligation as well as the sensitivity of our pension liability on December 31, 2022 and of the income statement charge in 2020, 2021 and 2022 to changes in these assumptions, is disclosed in Note 31 to our consolidated financial statements.

***Fair value of financial instruments***

When the fair value of financial assets and liabilities presented on the balance sheet cannot be obtained in active markets, it is determined using valuation techniques, including the method of discounted cash flow. The data obtained for the use of these methods are based as much on the information prevailing in the market as possible. However, when it is not feasible to obtain such information in the market, a certain assumption level is required to establish the fair value. The assumption includes consideration of the data that was used, such as the liquidity risk, credit risk and volatility. Changes in the assumptions regarding these factors could affect the presented fair value of financial instruments.

[**Table of Contents**](#TOC)

Additional information on fair value of financial instruments is disclosed in Note 32 to our consolidated financial statements.

***Taxes***

There may be uncertainties regarding the interpretation of complex tax regulations and the amount and timing of future taxable income. We record provisions based on reasonable estimates for potential disagreement with tax authorities from the jurisdictions in which we operate. The value of these provisions is based on several factors such as experience from previous tax audits and different interpretations of tax regulations by the taxable entity and the competent tax authority in charge. Such differences of interpretation may arise in a wide variety of subjects, depending on the prevailing conditions in the domicile of the company. As a result, we may be required to pay more than our provisions or to recover less than the related judicial assets recognized.

We evaluate the recoverability of deferred tax assets based on estimates of future results. This recoverability ultimately depends on our ability to generate taxable profits over the period in which the temporary difference is deductible. The analysis considers the reversal period of deferred tax liabilities, as well as estimates of profits from operations, based on updated internal projections reflecting the latest trends.

Determining the proper valuation of the tax items depends on several factors, including an estimate of the period and the realization of the deferred tax asset and the expected date of payments of these taxes. The actual flow of receipt and payment of income tax could differ from estimates made by us, as a result of changes in tax laws or of unexpected future transactions that may impact tax balances.

Additional information on taxes is disclosed in Notes 8 and 9 to our consolidated financial statements.

***Revenue recognition***

*Revenue recognition - revenue from unbilled services*

We have billing systems for services with intermediate cut-off dates. Thus, at the end of each month, there are revenues already received by us, but that are not effectively invoiced to our customers. These unbilled revenues are recorded based on estimates, which take into account historical consumption data, the number of days elapsed since the last billing date, among others. Because historical data are used, these estimates are subject to significant uncertainties.

Additional information on revenue recognition is disclosed in Note 25 to our consolidated financial statements.

Decisions of the Fiscal Board are not binding on the Company under Brazilian Corporate Law.

Our management considers relations with our workforce to be very good and we have never experienced a work stoppage for a significant period or that had a material effect on our operations.

***Pension Plans***

We have offered pension plans to our employees since before the privatization, which took place in 1998. In this period, the modality adopted was of plans of defined benefit, which were offered to employees until the year 2000, when we started offering defined contribution plans. These plans were administered exclusively by Fundação Sistel de Seguridade Social until 2005.

In 2005, we created a closed social security entity, called Visão Prev Sociedade de Previdência Complementar, to manage the pension plans of the Telefónica group in Brazil. From 2005 to 2010, management of all plans was transferred from Fundação Sistel to Visão Prev, except for PBS-A Plan (Plano de Benefício Sistel), intended for plan retirees, which continues to be managed by SISTEL.

On September 2013, we began offering the Visão Multi defined contribution plan to our employees. This plan was launched in order to standardize the benefit following the corporate restructuring process of the subsidiaries in Brazil. This is the plan available for new enrollments. In this plan, participants can make basic contributions of 1-2% on their participating salary and an additional 0-5% on the installment of the participating salary that exceeds the maximum (value in December of 2022 was R$4.399,22) and we contribute a percentage between 50% to 125%, depending on the employees' length of service.

Considering our total workforce, 30% of our employees are participants in our private pension plans.

[**Table of Contents**](#TOC)

**E.** Share Ownership

None of our directors or executive officers owns, on an individual basis, 1% or more of our common shares (including ADSs representing common shares) or of our total equity share capital.

***Performance Share Plan ("PSP") and Talent for the Future Share Plan ("TFSP")***

The annual shareholders' meeting of Telefónica S.A. (our indirect controlling shareholder), held on June 8, 2018, approved new long-term incentive plans, the Performance Share Plan ("PSP"), and the Talent for the Future Plan ("TFSP"), for executives of Telefónica S.A. and of other entities within the Telefónica group, including us.

The Plans provide for the possibility, for the executives of the Telefónica group that are invited to participate in it, to receive a certain number of shares of Telefónica after a period of three years, through the prior assignment of a certain number of theoretical shares or units ("Units"), which shall serve as a basis for determining the number of common shares in the capital stock of Telefónica ("Shares") which may be delivered under the Plan as variable compensation, depending on the achievement of the objectives set for each of the cycles in which the Plan is divided. The Plans shall have a total duration of five (5) years, and shall be divided into three (3) independent cycles (the "Cycles"), each with a measurement period of three (3) years, according to the following measurement calendar:

● First Cycle: from January 1, 2018 to December 31, 2020;

● Second Cycle: from January 1, 2019 to December 31, 2021; and

● Third Cycle: from January 1, 2020 to December 31, 2022.

At the end of each cycle, there is an evaluation to determine if the minimum performance conditions were met: Telefónica's total shareholder return ("TSR"), against a comparative set, and free cash flow goals ("FCF").

TSR is regarded as the metric to measure the generation of value to our shareholders in the medium- and long-term, for the purposes of the Plan, as the return on investment taking into account the cumulative change in the value of Telefónica shares and dividends and other similar items received by its shareholders during each cycle. The Weighting corresponding to this objective will be 50% (fifty percent) of the total number of Shares to be delivered to PSP participants.

The FCF is established as the plan's metric to encourage commitment to the sustainable achievement of long-term strategic objectives. This objective must be established and approved each year by our Board of Directors. 50% (fifty percent) of the number of Shares to be delivered under the Plan shall be determined based on the FCF level generated by the Company each year, comparing this with the amount set in the budgets approved by our Board of Directors for each year. In this regard, the partial achievement of this objective shall be calculated annually, and the final FCF shall be an average of the partial achievements calculated each year.

In order to receive Shares under the Plan, participants must meet the following requirements in each of the cycles:

● Maintain, for at least 12 months of the Cycle, an active relationship with the Company or any of our subsidiaries and, at the start date of each Cycle, participate in the plan and comply with the General Conditions (the "Subsidiary" or the "Participating Company").

● Maintain, on the delivery date, an active relationship with a participating company.

● Exceed the minimum levels of achievement of the Plan's objectives.

In case of termination, only if it occurs 12 months after their start date and in accordance with the plan's rules.

The plans in effect on December 31, 2022 were:

[**Table of Contents**](#TOC)

● PSP – Cycle 2020-2022: with 76 executives (including 3 executives nominated by the Bylaws) of Telefônica Brasil having the right to potentially receive 469,757 Telefônica S.A. shares.

● TFSP – Cycle 2020-2022: with 134 executives of Telefônica Brasil having the right to potentially receive 107,600 Telefônica S.A. shares.

Telefónica S.A.'s (our indirect controller) general shareholders' meeting on April 22 and 23, 2021, approved new long-term incentive plans, Performance Share Plan ("PSP") and Talent for the Future Plan ("TFSP"), for Telefónica S.A.'s employees and of other companies within Grupo Telefónica, including the Company.

The Plans consist of the possibility, for the Telefónica Group executives who are invited to participate in it, to receive a certain number of Telefónica shares after a period of three years, through the prior assignment of a certain number of theoretical shares or units ("Units"), which will serve as a basis for determining the number of common shares in Telefónica's capital stock ("Shares") which may be delivered under the Plan as variable compensation, depending on the achievement of the objectives set for each of the cycles in which the Plan is divided. The plans will have a total duration of five years, and will be divided into three independent cycles (the "Cycles"), each with a measurement period of three years, according to the following measurement calendar:

● First Cycle: from January 1, 2021 to December 31, 2023;

● Second Cycle: from January 1, 2022 to December 31, 2024; and

● Third Cycle: from January 1, 2023 to December 31, 2025.

At the end of each cycle, there is an evaluation to determine if the minimum performance conditions were met: Telefónica's total shareholder return ("TSR"), relative to a peer group, free cash flow targets ("FCF") and the neutralization and reduction of CO² emissions.

TSR is regarded as a metric to determine the generation of value to our investors in the medium and long term, for the purposes of the Plan, as the return on the investment taking into account the cumulative change in Telefónica's share value and dividends and other similar items received by the shareholder in that cycle. The Weighting corresponding to this objective will be 50% (fifty percent) of the total number of shares to be delivered to PSP participants.

FCF is established as the plan's metric seeking to incentivize the commitment to the sustainable development of the strategic goals in the long term. This goal must be established and approved annually by our Board of Directors. 40% (forty percent) of the number of shares to be delivered by the Plan will be determined based on the level of FCF generated by the Company each year, comparing it to the value defined in the budgets approved annually by our Board of Directors. In this sense, the partial achievement of this goal will be calculated annually, and FCF's final achievement will be an average of the partial achievements calculated each year.

10% (ten percent) of the number of shares to be delivered by the Plan will be determined according to the level of CO² emissions neutralization ("Emissions Neutralization") reached at the end of the cycle, being necessary to reach a certain level of reduction of emissions of 1+2 ("Emissions Reduction"), in line with the 1.5ºC of the Paris Agreement (SBTi) and with the goal established by the Company of zero net emissions for the year 2025 in its core markets for the 1+2 scopes.

In order to receive Shares under the Plan, participants must meet the following requirements in each of the cycles:

● Maintain, for at least (12) months of the Cycle, an active relationship with the Company or any of our subsidiaries and, at the start date of each Cycle, participate in the plan and comply with the General Conditions (the "Subsidiary" or the "Participating Company").

● Maintain, on the delivery date, an active relationship with a participating company.

● Exceed the minimum levels of achievement of the Plan's objectives.

In case of termination, only if it occurs 12 (twelve) months after their start date and in accordance with the plan rules.

[**Table of Contents**](#TOC)

The plans in effect as of December 31, 2021 were:

● PSP – Cycle 2021-2023: with 83 executives (including 3 executives appointed by our Bylaws) of Telefônica Brasil having the right to potentially receive 1,654,058 Telefônica S.A. shares;

● PSP – Cycle 2022-2024: with 103 executives (including 3 executives appointed by our Bylaws) of Telefônica Brasil having the right to potentially receive 865,821 Telefônica S.A. shares;

● TFSP – Cycle 2021-2023: with 173 executives of Telefônica Brasil having the right to potentially receive 295,000 Telefônica S.A. shares; and

● TFSP – Cycle 2022-2024: with 136 executives of Telefônica Brasil having the right to potentially receive 289,500 Telefônica S.A. shares.

#### Performance Share Plan VIVO ("PSP")
We approved an incentive plan Performance Share Plan ("PSP VIVO") via performance units, with cash settlement ("Plan"). Plan participants will be entitled to the grant of a certain number of representative units of one share issued by us (VIVT3) ("Unit" and "Share"). Each Unit represents the expectation of the right to receive the full amount of one Share, which shall serve as a basis, considering the number of Units received, to determine the value of the incentive to be paid by the Company in cash to the participants.

The delivery of the incentive is conditioned to: (i) keeping an active work relationship at Telefónica group at the date of consolidation of the cycle; and (ii) the achievement of results that represent the fulfilment of the objectives established for the plan.

The level of success is based on comparing the evolution of shareholder remuneration, considering share price and dividends (Total Shareholder Return – TSR) of our share, in relation to the evolution of the TSRs of the companies in the pre-defined Comparison Group, the achievement of our FCF (Free Cash Flow) and the neutralization and reduction of CO² emissions.

The plans in effect as of December 31, 2022 were:

● PSP – Cycle 2022-2024: with 101 executives of Telefônica Brasil having the right to potentially receive 431,607 Company shares.

#### Telefónica Global Incentive Share Purchase Plan: Plan 100
Employees enrolled in the plan can acquire Telefónica shares through monthly contributions of 25 euros to 150 euros (or the equivalent in local currency), deducted from payroll, monthly with a maximum amount of 1,800 euros over a twelve-month period (purchase period).

The six months following the purchase period are the retention period for the purchased shares. At the end of this period, additional shares will be delivered, that is, for each share purchased by the employee, one free share will be granted.

The cycle of this plan is effective from September 1, 2022 to March 31, 2024.

The delivery of shares will occur after the vesting period of the plan, after March 31, 2024, and is conditioned to: (i) remaining in the company during the two-year duration of the program (vesting period), subject to certain special conditions in relation to layoffs; and (ii) the exact number of shares to be delivered at the end of the vesting period depends on the number of shares acquired and held by employees. Thus, employees enrolled in the plan, who remain in the Telefónica Group, who have held the shares acquired for an additional period of six months after the end of the purchase period, will be entitled to receive one free share for each share they have acquired and retained until the end of the vesting period.

To commemorate the 100th anniversary of Telefónica's incorporation (April 19, 2024), in addition to the Additional Shares, each of the participants may receive 100 Telefónica Commemoration Shares ("the Commemoration Shares") free of charge.

#### Item 7. Major Shareholders and Related Party Transactions
**A.** Major Shareholders

In accordance with our bylaws, we have one class of capital stock authorized and outstanding: common shares (*ações ordinárias*), which have full voting rights.

On December 31, 2022, Telefónica owned 37.83% of our common shares and Telefónica LATAM owned 36.31% of our common shares. Since Telefónica LATAM is a wholly-owned subsidiary of Telefónica, Telefónica has effective control over 74.20% of our outstanding common shares. Accordingly, Telefónica can control the election of our board of directors and to determine the direction of our strategic and corporate policies. None of Telefónica or Telefónica LATAM has any special voting rights beyond those ordinarily accompanying the ownership of our common shares.

SP Telecom, a former controlling shareholder of ours, was liquidated and extinguished on October 31, 2022. The shares issued by the Company and held by SP Telecom were delivered to its partners Telefónica and Telefónica LATAM, in the proportion of their respective participation in the social capital of the Society, within the scope of the sharing of shareholders' equity. Therefore, Telefónica received 131,069,752 shares, and Telefónica LATAM received 201,625,838 shares, in each case issued by Telefônica Brasil.

Telefónica's shares are traded on various stock exchanges, including exchanges in Madrid, Barcelona, Bilbao, Valencia, London, New York, Lima and Buenos Aires.

Telefónica is one of the largest telecommunications companies in the world in terms of market capitalization and number of customers. With its strong mobile, fixed and broadband networks and its innovative portfolio of digital solutions, Telefónica is transforming itself into a "Digital Telco", a company that will be even better placed to meet the needs of its customers and capture new revenue growth.

The following tables set forth information relating to the ownership of common shares by Telefónica, Telefónica LATAM, any other shareholders known to us to beneficially own more than 5% of our common shares and our officers and directors, based on 1,676,938,271 common shares outstanding as of December 31, 2022 (excluding treasury shares). We are not aware of any other shareholder that beneficially owns more than 5% of our common shares.

**Legal Proceedings**

We are party to legal proceedings incidental to the normal course of our business. The main categories of such proceedings include:

● other civil suits, including litigation arising out of the breakup of Telebrás, and events preceding the breakup.

Our policy with respect to provisioning for contingencies classifies the various legal proceedings to which we are party as "probable," "possible" and "remote". We and our subsidiaries are parties to labor, tax, civil and regulatory claims and set up a provision for contingencies for which the likelihood of loss was estimated as probable. Our senior management classifies each legal proceeding into one of these three categories (probable, possible and remote) based upon the advice of internal and external counsel and specialized technical advisors in charge of each matter. Due to the level of provisioning and based on its analysis of the individual cases, our management believes that no additional liabilities related to any legal proceedings will have a material effect on our financial condition or results of operations, other than as described below.

There are no material proceedings in which any of our directors, any members of our senior management, or any of our affiliates is either a party adverse to us or to our subsidiaries or has a material interest adverse to us or to our subsidiaries.

***Tax Matters* — *Probable Loss***

The following tax proceedings were pending as of December 31, 2022, and, in the opinion of our management and our legal advisors, the chance of loss in these cases is probable.

***FUST, FUNTTEL and FISTEL Litigation***

*FUST Litigation*

Fixed-line and mobile operators filed suit seeking a writ of mandamus to recognize their right to include interconnection revenue in the FUST base for mobile services. We have challenged such charges and the proceedings are waiting to be tried in the court of appeals. As a result, ANATEL charges us with various infractions to collect tax credits and other revenues that were not obtained from the provision of telecommunication services, on which ANATEL believes FUST is due. As of December 31, 2022, the total amount under discussion in these proceedings R$5,103.0 million. In the opinion of our management and our legal advisors, our chance of loss in the foregoing proceedings is possible, and, consequently, we have not made any provisions in connection with these proceedings.

*FUNTTEL Litigation*

On December 31, 2022, we were a party to administrative and judicial proceedings, which are waiting to be tried at the lower administrative court and the court of appeals. Such proceedings concern the collection of contributions to FUNTTEL on other revenues (not related to telecom services), as well as on income and expenses transferred to other operators (interconnection). As of December 31, 2021, the total amount under discussion in these proceedings R$1,013.4 million. In the opinion of our management and our legal advisors, the chance of loss in the foregoing proceeding is possible, but not probable and, consequently, we have not made any provisions in connection with this proceeding.

*FISTEL Litigation*

Due to the extension of the effective license period to use telephone switches in connection with the use of landline phone carriers, and the extension of the right to use radiofrequency in connection with wireless service (wireless carriers), ANATEL charges us with an installation inspection fee (*taxa de fiscalização e inspeção*), or the TFI. This collection is based on ANATEL's understanding that such extension would represent a taxable event for the TFI. We understand that such collection is inappropriate, and challenged this fee in court. As of December 31, 2022, the total amount under discussion in these proceedings was R$2,122.8 million, without the respective deposit in full. In the opinion of our management and our legal advisors, the chance of loss in the foregoing proceeding is possible and, consequently, we have not made any provisions in connection with this proceeding.

***Labor Litigation***

We are a defendant in several lawsuits filed by former employees and outsourced employees (subsidiary or solidary responsibility), which claim, among others: overtime payments, variable compensation, salary parity, and unhealthy or risk work premiums. We have recorded R$540.2 million in provisions for these proceedings where the risk of loss is deemed probable. We are also defendants in certain other labor claims for which the chance of loss is deemed possible, which totaled an aggregate amount of approximately R$1,490.6 million as of December 31, 2022, and for which we have not recorded provisions.

[**Table of Contents**](#TOC)

***Civil Claims***

We are the defendants in multiple civil claims. We have recorded R$1,192.9 million in provisions in connection with these proceedings as of December 31, 2022 where the risk of loss is deemed probable, including the civil proceedings described below:

● We are defendants in proceedings related to the possible right of individuals who purchased our shares in connection with our network expansion plan after 1996 to receive additional shares from us. These claims are in course through the various levels of the court system and the success rate in each proceeding is classified on a case-by-case basis according to the facts presented in each proceeding. For proceedings in which our chance of loss has been estimated as probable, we recorded provisions in the amount of R$145.9 million as of December 31, 2022 (R$130.2 million as of December 31, 2021).

● We and/or our subsidiaries are defendants in various civil proceedings related to individual consumers' claims in judicial courts, especially relating to our failure to perform our services. As of December 31, 2022, provisioned amounts in connection with these proceedings totaled R$244.7 million (R$367.3 million as of December 31, 2021).

● We and/or our subsidiaries are parties to various civil, non-consumer and consumer proceedings in administrative and judicial courts arising out of the ordinary course of business. As of December 31, 2022, provisioned amounts in connection with these proceedings totaled R$802.4 million (R$438.5 million as of December 31, 2021).

Other several civil claims against us for which the chance of loss is deemed possible totaled approximately R$2,174.3 million as of December 31, 2022 and for which we have not recorded provisions, including:

● The National Federation of Associations of Retirees and Pensioners and Participants in Pension Funds in Telecom (*Federação Nacional das Associações de Aposentados, Pensionistas e Participantes em Fundo de Pensão do Setor de Telecomunicações.*) filed a class action against the Company seeking the annulment of the spin-off of the PBS pension benefit plan (which occurred in 2000 and led to the creation of a specific TELESP–PBS pension benefit plan) and the corresponding allocation of resources resulted from the technical surplus and fiscal contingencies existing at that time. The lower court ruled against the Company. Subsequently, an appellate court held that the state courts lacked jurisdiction to hear the case, and referred the case to the federal courts for retrial. Fenapas presented an agreement signed by the parties. The agreement was ratified by the court, extinguishing the process. We are currently awaiting certification of the final and unappealable decision and filing of the case. Our risk of loss in this proceeding has been estimated as possible based on the opinion of our legal advisors. The amount involved cannot yet be determined until an expert appraisal report is completed.

● The São Paulo Sistel Participants' Association (*Associação dos Participantes do Sistel no Estado de São Paulo*) filed a class action that challenges changes made to the health care plan for the association's retired employees. While an appeal in this proceeding was pending adjudication, the parties entered into a settlement agreement with judicial confirmation.

● We are a party to various other civil claims related to our services. Such claims were filed by individual consumers, civil associations representing consumer rights, or by PROCON, as well as by federal and state public prosecutor offices. We are also party to various other claims in the ordinary course of our business.

*Ownership of Caller ID*

Lune Projetos Especiais Telecomunicação Comércio e Ind. Ltda., or Lune, filed on November 20, 2001 lawsuits against 23 wireless telecommunications operators, including TELESP Celular Participações and its subsidiaries. The lawsuits allege that those operators violated patent No. 9202624-9, related to *Equipamento Controlador de Chamadas Entrantes e do Terminal do Usuário*, or Caller ID, granted to Lune by the Brazilian Institute of Industrial Property (*Instituto Nacional da Propriedade Industrial*) on September 30, 1997. An unfavorable decision was handed down determining that the Company should refrain from selling mobile phones with Caller ID service, subject to a daily fine of R$10,000 in case of noncompliance. Furthermore, according to that decision, the Company must pay indemnification for royalties, to be calculated at settlement. Motions for clarification were opposed by all parties and Lune's motions for clarification were accepted, since an injunctive relief in this stage of the proceedings was deemed applicable. An appeal was filed against a decision that granted a stay of execution until final judgment of an appeal on the merits. This latter appeal was successful and granted the Company the right to a new trial by the lower court. In the second trial, the lawsuit was ruled in our favor. Lune has filed an appeal, which is pending adjudication. Our outside counsel's opinion is that the chance of an

[**Table of Contents**](#TOC)

unfavorable outcome is possible. We are unable to determine at this time the extent of any potential liabilities with respect to this claim.

*Expiration of Prepaid Plan Minutes*

We, together with other Brazilian wireless telecommunications operators, are defendants in lawsuits brought by public prosecutor offices and consumer protection associations challenging the imposition of a deadline for the use of purchased prepaid minutes. The plaintiffs allege that purchased prepaid minutes should not expire after any specified deadline. Conflicting decisions have been issued by the courts about this matter. Although we believe that our criteria for imposing the deadline are in compliance with ANATEL's rules, we believe, based on the opinion of outside counsel, that the likelihood of an unfavorable outcome with respect to these claims is possible.

***Regulatory and Antitrust Litigation***

We are involved in several regulatory and antitrust administrative and legal proceedings. As of December 31, 2022, proceedings with a possible risk of loss amounted to R$5.8 billion. Our material regulatory and antitrust administrative and legal proceedings for which the chance of loss is deemed probable include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) We are a party to administrative proceedings initiated mainly by ANATEL on the grounds of alleged non-compliance with obligations in the sectoral regulations, as well as in lawsuits that discuss, in the great majority, sanctions applied by ANATEL at the administrative level. The main themes of these proceedings are the obligation to pay the onerous fee for the renewal of radio frequencies (the payment, due every two years, relating to the right to use of radio frequencies), our obligations related to non-observance of the rights of consumers of telecommunications services, the achievement of ANATEL's quality indicators, and the achievement of targets contained in the spectrum auction notice for service coverage.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) A dispute arose on which revenues should be considered in the payment of amounts due for the renewal of radio frequencies in relation to the payment of SMP charges. We, together with our legal advisors, concluded that there is a probable loss of approximately R$673 million on the payment of the SMP burden in relation to data revenue, due to the existence of unfavorable decisions at ANATEL and in the courts with an unlikely chance of review. Moreover, we decided to begin collecting such amounts in favor of ANATEL.

Our material regulatory and antitrust administrative and legal proceedings for which the chance of loss is deemed possible include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Administrative and legal proceedings discussing how ANATEL should calculate a payment due every two years relating to the extension of STFC concession agreements and the right of use SMP-related radio frequencies. In ANATEL's view, a 2% charge should be calculated on all of our STFC/SMP revenue. In our view, however, the revenues that are not part of the STFC/SMP service plans, as defined by regulation at the time of signing the authorization terms/concession agreements, should not be taken into account when calculating the fee. As a result of this disagreement, we filed administrative and legal proceedings challenging ANATEL's charges.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) A lawsuit to invalidate ANATEL's March 2018 decision in an administrative proceeding where it charged us with violations of fixed-line telephone regulations. In particular, we were charged with breaching rules on the prior notice required to terminate service to users in default and related refunds. ANATEL imposed a fine of approximately R$199.1 million, which as of December 31, 2022, amounted to approximately R$574.8 million (after interest and monetary adjustments). We have not paid this fine, but have guaranteed its payment through litigation insurance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) An investigation by CADE in connection with a joint bid we submitted with Claro and Oi, through a consortium, for certain services to be rendered to the Empresa Brasileira de Correios e Telégrafos, the Brazilian state postal service. We have presented our defense, in which we allege our joint big was lawful under the applicable laws. The CADE's general body decided that the operators engaged in anti-competitive conduct. After the decision, Telefonica filed a motion for clarification and is now awaiting its judgment.

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Administrative Proceeding started by ANATEL to investigate possible measures regarding the possibility of transfer of economic gains arising from the decision of the Brazilian Supreme Court (STF), which excluded ICMS from the PIS/COFINS calculation base between 2002 and 2017 in the fixed telephone concession plans. In such case, ANATEL's superintendence understood, in connection with the Prosecutor's legal opinion, that such gains are not a result of business efficiency, but from a change in the tax order. The devolution proposal suggested by ANATEL would be through a tariff review for the fixed telephone basic plans and the construction of high capacity backhaul infrastructure for alternative plans, totaling approximately R$1 billion, which we assess, at this time, as a possible chance of loss. The case will be judged by the Board of Directors of ANATEL, from which it may be challenged through an arbitration procedure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) Administrative Proceeding started by Anatel, which dealt with mobile coverage goals, whose fine of R$127 million could be converted into an alternative Obligation ("OdF"), which consists of an alternative means of complying with a fine, by investing in the installation of 4G ERBs in 188 locations, whose installation must take place in 2 and a half years, with maintenance costs equivalent to the period of 1 year. Installation cannot result from RAN Sharing, Swap, network rental, industrial exploitation contracts, or other contractual means. The deployment of such Obligation within the established period will be monitored.

**Dividends and Dividend Distribution Policy**

***Priority and Amount of Dividends***

The Brazilian Corporate Law determines that the shareholders of a company have the right to receive a minimum percentage of the distributable profits (mandatory dividends) comprising dividends and/or interest on shareholders' equity, or distributable amount, of the corporation for each fiscal year. If such amount is not determined in the bylaws of the company, Brazilian Corporate Law specifies the criteria to determine the minimum amount of the dividend. See "Item 10. Additional Information—B. Memorandum and Articles of Association."

According to our bylaws, we are required to distribute as mandatory dividends of each fiscal year ending on December 31, to the extent amounts are available, an aggregate amount equal to at least 25% of adjusted net income.

As per our bylaws, our Board of Directors may declare interim dividends based on (i) the accrued profits recorded in our semiannual financial statements; (ii) the accrued profits recorded in our quarterly financial statements or in our financial statements of shorter periods, provided that the total amounts of dividends paid up every six months does not exceed the total amount within the capital reserve determined per article 182 of Brazilian Corporate Law; and (iii) the amount recorded on the profit account or profit reserve account on our last annual or semiannual financial statements.

Under the Brazilian Corporate Law, a company is allowed to withhold payment of the mandatory dividend in respect of common shares (and also ADSs) if:

● management and the fiscal board report at the shareholders meeting that the distribution would be incompatible with the financial circumstances of the company; and

● the shareholders ratify this decision at the shareholder's meeting.

If that is the case:

● management must forward to the CVM, within five days of the shareholders meeting, an explanation justifying the decision at the shareholders meeting; and

● the profits that were not distributed are to be recorded as a special reserve and, if not absorbed by losses in subsequent fiscal years, are to be paid as dividends as soon as the company's financial situation allows.

For the purposes of the Brazilian Corporate Law, net profits are defined as net income after income tax and social contribution for the fiscal year, net of any accumulated losses from prior fiscal years and any amounts allocated to beneficiary parties', employees' and management's participation in a company's profits and subscription bonuses.

[**Table of Contents**](#TOC)

Under Brazilian Corporate Law, adjusted net income is an amount equal to our net income adjusted to reflect allocations to or from (i) legal reserves, and (ii) contingency reserves for anticipated losses, if any.

At each annual shareholders meeting, the board of directors is required to suggest the allocation of net profits obtained during the preceding fiscal year. Under Brazilian Corporate Law, we are required to maintain a legal reserve, to which 5% of our net profits must be allocated for each fiscal year, until the reserve amounts to 20% of our paid-in capital. Net losses, if any, shall be deducted from accumulated profits, profit reserves and legal reserve, in this order.

Brazilian Corporate Law also provides for an additional allocation of net profits to special accounts, also to be recommended by management and subject to approval by shareholders at the annual shareholders meeting, including the amount of net profits that may be allocated to the contingency reserve for anticipated losses that are deemed probable in future years. Any amount so allocated in a previous year must be either:

● reversed in the fiscal year in which the loss was anticipated, if the loss does not in fact occur; or

● written-off if the anticipated loss occurs.

Net profits may also be allocated to the unrealized income reserve in case the total amount of mandatory dividends exceeds the amount of realized net income. Such allocation should also be suggested by management and subject to approval by shareholders at the shareholders' meeting. For such purpose, realized income is the balance of net profits exceeding the sum of:

● the positive net result of equity adjustment; and

● earnings, revenues or net profits from transactions or the accounting of assets and liabilities at market value, whose financial realization term occurs after the end of the next fiscal year.

The amounts available for distribution are determined on the basis of financial statements prepared in accordance with the accounting practices adopted in Brazil.

***Payment of Dividends***

We are required by law and our bylaws to hold an annual shareholders meeting until April 30 of each year to approve, among other issues, the allocation of net profits earned during the preceding fiscal year and the declaration of dividends by a decision of common shareholders, acting on the recommendation of the executive officers, as approved by the board of directors. The payment of annual dividends is based on the financial statements prepared for each fiscal year ending on December 31. Under the Brazilian Corporate Law, dividends are required to be paid within 60 days following the date the dividend is declared to the shareholders of record on the declaration date, unless a resolution by the shareholders sets forth another date of payment, which must occur before the end of the fiscal year.

A shareholder has a three-year period from the dividend payment date to claim dividends in respect of its shares, after which any unclaimed dividend distributions legally revert to the Company. Because our shares are issued in book-entry form, dividends with respect to any share are credited to the account holding the share and no action is required on part of the shareholder. We are not required to adjust the amount of paid-in capital for inflation.

***Time Limits for Claiming Dividends***

Our shareholders have 3 years to claim dividend distributions made with respect to their shares, as from the date that we distribute the dividends to our shareholders, after which any unclaimed dividend distributions legally revert to us. We are not required to adjust the amount of any distributions for inflation that occurs during the period from the date of declaration to the payment date.

If a shareholder is not a resident of Brazil, he or she must register with the Central Bank to be eligible to receive dividends, sales proceeds or other amounts with respect to his or her shares outside of Brazil. Our common shares underlying ADSs are held in Brazil by a Brazilian custodian, Citibank DTVM S.A., as the agent for the depositary Citibank N.A., which is the registered owner of our shares.

[**Table of Contents**](#TOC)

Payments of cash dividends and distributions, if any, will be made in Brazilian currency to the custodian on behalf of the depositary, which will then convert those proceeds into U.S. dollars and will provide for U.S. dollars to be delivered to the depositary for distribution to holders of ADSs. If the custodian is unable to immediately convert the Brazilian currency received as dividends into U.S. dollars, the amount of U.S. dollars payable to holders of ADSs may be adversely affected by devaluations of the Brazilian currency that occur before dividends are converted and remitted. Dividends in respect of the common shares paid to resident and nonresident shareholders, including holders of ADSs are not currently subject to Brazilian withholding tax.

***Additional Payments on Shareholders' Equity***

Law No. 9,249, as amended December 26, 1995, provides for the distribution to shareholders of interest on shareholders' equity, which may be computed with the amount of dividends to be distributed to shareholders. A company can treat these payments as financial expenses for income tax and social contribution purposes. Currently, this interest is limited to the daily pro rata variation of the TJLP, a long-term nominal interest rate determined by the federal government that includes an inflation factor and cannot exceed the greater of:

● 50% of net income (before deducting income tax and interest on equity) for the period in which the payment is made, or

● 50% of the sum of retained earnings and profit reserves.

Currently, any payment of interest in respect to common shares to shareholders (including the holders of ADSs) is subject to Brazilian withholding tax at a rate of 15%, or 25% in the case of a shareholder domiciled in a tax haven, and these payments may be included, at their net value, as part of any mandatory dividend. If payment of interest on shareholders' equity is made for a beneficiary located outside of Brazil, the IOF tax triggers at a rate of zero. See "Item 10. Additional Information—E. Taxation—Brazilian Tax Considerations—Distributions of Interest on Capital."

We declare and pay dividends and/or interest on shareholders' equity as required by Brazilian Corporate Law and our bylaws. The declaration of annual dividends, including dividends in excess of the mandatory distribution, requires approval by the vote of a majority of the holders of common shares, and depends on many factors. These factors include our results of operations, financial condition, cash requirements, future prospects and other factors deemed relevant by shareholders. Our shareholders have historically acted on these matters based on recommendations by the board of directors.

The following table sets forth the dividends or interest on shareholders' equity paid to holders of our common and preferred shares since 2017 in *reais*:

Not applicable.

**C.** Markets

***Regulation of Brazilian Securities Markets***

The Brazilian securities market is regulated and supervised by the CMN (which has general authority over the stock exchanges and securities markets), as provided for by the Brazilian Securities Exchange Act and Brazilian Corporate Law. The CMN is responsible for supervising the CVM's activities, granting licenses to brokerage firms to govern their incorporation and operation, and regulating foreign investment and exchange transactions, as provided for by the Brazilian Securities Exchange Act and Law No. 4,595 of December 31, 1964, as amended. These laws and regulations provide for, among other things, disclosure requirements to issuers of

[**Table of Contents**](#TOC)

securities listed on stock exchanges, criminal sanctions for insider trading and price manipulation, protection of minority shareholders, the procedures for licensing and supervising brokerage firms and the governance of Brazilian stock exchanges.

Under Brazilian Corporate Law, a company is either publicly held and listed, a *companhia aberta*, or privately held and unlisted, a *companhia fechada*. All listed companies are registered with the CVM and are subject to reporting requirements to periodically disclose information and material facts. A company registered with the CVM is authorized to trade its securities either on the Brazilian exchange markets, including the B3, or in the Brazilian over-the-counter market. Shares of companies listed on the B3 may not simultaneously trade on the Brazilian over-the-counter markets. The over-the-counter market consists of direct trades between persons in which a financial institution registered with the CVM serves as an intermediary. No special application, other than registration with the CVM (and, in case of organized over-the-counter markets, with the relevant over-the-counter market), is necessary for securities of a publicly held company to be traded in this market. To be listed on the B3, a company must apply for registration with the B3 and the CVM.

Trading in securities on the B3 may be suspended under a request from a company in anticipation of a material announcement. Trading in the securities of a particular company may also be suspended under the initiative of the B3 or the CVM, among other reasons, due to the belief that the company has provided inadequate information regarding a material event or has provided inadequate responses to inquiries by the CVM or the B3.

***Trading on the B3***

B3 is a Brazilian publicly held company established in March 2017 when the securities, commodities and futures exchanges activities of BM&FBOVESPA were combined with the activities of CETIP, a provider of financial services for the organized OTC market. B3 is one of the world's largest financial market infrastructure providers by market value. The services it offers range from exchange trading, clearing and other post-trade services to registration of over-the-counter (OTC) transactions and of vehicle and real estate loans.

Trading on the exchange is conducted by authorized members. Trading sessions take place every business day, from 10:00 a.m. to 5:00 p.m., during daylight savings time in the United States, or from 10:00 a.m. to 6:00 p.m., on an electronic trading system called PUMA. Trading is also conducted between 5:30 p.m. and 6:00 p.m., in the period when the trading sessions close at 5:00 p.m., in an after-market system connected to both traditional brokerage firms and brokerage firms operating on the Internet. This after-market trading is subject to regulatory limits on price volatility of securities traded by investors operating on the Internet.

To better control the excess of volatility in market conditions, B3 has adopted a "circuit breaker" system pursuant to which trading sessions may be suspended for a period of 30 minutes or one hour whenever the indices of these stock exchanges fall below the limits of 10% and 15%, respectively, compared to the index at the close of trading of the previous trading day. In the event the stock exchange index falls below the limit of 20% in comparison to the previous trading day, B3 may determine the suspension of trading sessions for a certain period to be defined at its sole discretion.

Although all the outstanding shares of an exchange-listed company may trade on a Brazilian stock exchange, in most cases, less than half of the listed shares are actually available for trading by the public, the remainder being held by small groups of controlling entities or persons that rarely trade their shares. For this reason, data showing the total market capitalization of Brazilian stock exchanges tends to overstate the liquidity of the Brazilian equity securities market.

***Corporate Governance Practices***

We are a *sociedade anônima*, a corporation incorporated under the laws of Brazil, and are subject to the corporate governance provisions set forth within Brazilian Corporate Law. We comply with the regulatory requirements of the Brazilian Corporate Law regarding the independence of our board of directors, the establishment and composition of certain board committees and the adoption and disclosure of corporate governance guidelines.

We comply with several requirements of Brazilian and international laws to promote strong corporate governance, reduce investor uncertainties and enhance disclosure of material and other information.

[**Table of Contents**](#TOC)

With the approval of our board of directors and/or Officers, we implemented several measures over the last few years designed to improve our transparency and disclosure practices. We believe these measures will benefit our shareholders, and current and future investors as well as the marketplace in general. Among the measures we have implemented, we have:

● created a policy for disclosure of material facts or corporate actions and trading of our securities (*Política de Divulgação de Ato ou Fato Relevante e de Negociação de Valores Mobiliários*);

● created a policy for internal controls related to the Communication, Recording and Control of Financial and Accounting Information (*Normativa sobre Registro, Comunicação e Controle de Informação Financeiro-Contábil*);

● established the Quality and Sustainability Committee;

● established the Control and Audit Committee;

● established the Nominations, Compensation and Corporate Governance Committee;

● established the Strategy Committee;

● enacted a procedure to receive and deal with reports of accounting and auditing fraud within the company (*Canal de Denúncias*);

● enacted a policy for prior approval of contracting audit services (*Normativa sobre Aprovação Prévia de Serviços a serem Prestados pelo Auditor Externo*);

● enacted a code of business conduct and ethics (*Princípios de Negócio Responsável*);

● enacted a code of conduct for members of our finance team regulating the conduct of our managers in connection with the registration and control of financial and accounting information and their access to privileged and nonpublic information and data (*Normas de Conduta para Financeiros*);

● enacted a policy regarding communication of information to the securities market (*Normativa sobre Comunicação de Informação aos Mercados*); and

● enacted a policy regarding the prevention and fight against corruption (*Diretrizes de Prevenção e Combate à Corrupção and Política Anticorrupção*).

As determined by the Brazilian Corporate Law, the annual cap for the aggregate compensation of the board of directors and Board of Executive Officers is approved by our shareholders at a shareholders' meeting. The Nominations, Compensation and Corporate Governance Committee provides information and recommendations to the board of directors regarding the criterion for compensation.

Our policy relating to insider trading currently in effect is determined pursuant to our *Política de Divulgação de Ato ou Fato Relevante e de Negociação de Valores Mobiliários* in accordance with corporate law. This document establishes practices for disclosing, using and preserving the confidentiality of relevant acts and/or facts of the Company, and establishes obligations and mechanisms for the disclosure of said facts to the market. The Company, controlling Shareholders, senior management, members of our Board of Directors, Fiscal Board and any other employee exposed to sensitive information are subject to the restrictions imposed by such rules. In addition to the prohibition on the trading of our shares by such individuals when in possession of insider information, the rules establish blackout trading periods for those periods when insider information is available. In addition, the charter sets forth instructions for dealing with conflicts of interest and mandates disclosure of any such situation.

**Code of Business Conduct and Ethics**

Although adoption of a code of ethics is not required by Brazilian Corporate Law, we implemented a code of business conduct and ethics called the Telefónica Responsible Business Principles (*Princípios de Negócio Responsável*), which regulates the conduct of

[**Table of Contents**](#TOC)

our employees in general (including senior financial officers and executive officers) to comply with the requirements of the Sarbanes-Oxley Act and NYSE rules. See "Item 16b. Code of Ethics."

***General***

We are registered with the Board of Trade of São Paulo (*Junta Comercial de São Paulo*), or JUCESP, under No. 35.3.001588-14. We have been duly registered with the CVM under No. 17671 since August 19, 1998. Our headquarters are located in the city of São Paulo, state of São Paulo, Brazil.

At a special meeting of holders of our preferred shares, held on that same date, our preferred shareholders ratified the conversion of all of our preferred shares into common shares. After the conversion of the preferred shares into common shares, which formally occurred after the market closed on November 20, 2020, as approved by our shareholders on October 1, 2020, our subscribed and fully-paid share capital was R$63,571,415,865.09 divided into 1,690,984,923 common shares, all with no par value (including 2,291,147 treasury shares).

***History of Share Capital***

*Public Offering for the Primary Distribution of Common and Preferred Shares*

At a meeting held on March 25, 2015, our board of directors approved unanimously the realization of a public offering for the primary distribution of common and preferred shares issued by the Company, all registered shares, without par value, free and clear of any liens or encumbrances, including in the form of ADSs, represented by ADRs, held simultaneously in Brazil and abroad, through a capital increase of the Company. The capital increase was approved by the board of directors' meeting held on April 27, 2015, amounting to R$15.8 billion, increasing the Company's share capital from R$37.8 billion to R$53.6 billion through the issuance of 121,711,240 common shares, at an issue price of R$38.47 per unit, and 236,803,588 preferred shares, at an issue price of R$47.00 per unit. Common shares, preferred shares and ADSs issued as a result of this capital increase confer to their holders, as of April 28, 2015, the date of disclosure of the global offering announcement of commencement, the same rights assigned respectively to the holders of common shares, preferred shares and ADSs, currently outstanding, under the Company's bylaws and the Brazilian Corporate Law, fully participating in dividends and other distributions declared from the date of publication of the global offering announcement of commencement. The issue price of R$47.00 per preferred share was determined after the completion of the bookbuilding process, in accordance with article 23, paragraph 1, and article 44 of CVM Instruction No. 400/2003, as amended, or Instruction No. 400, and in accordance with the provisions of article 170, paragraph 1, item III, of the Brazilian Corporate Law. The issue price of R$38.47 per common share was determined based on the price per preferred share determined after the completion of the bookbuilding process, applying a discount of 18.14%, which represents the average price discount trading of the common shares issued by the Company in relation to the trading price of the preferred shares issued by the Company in the three months prior to March 26, 2015.

At a meeting held on April 30, 2015, our board of directors approved a second capital increase in connection with the public offering for the primary distribution of shares, due to the exercise, by the Bank of America Merrill Lynch Banco Múltiplo S.A., of the option of over-allotment of shares that was granted by the Company, in accordance with article 24 of Instruction No. 400, to meet the excess demand verified during the Offering. The Company's share capital was increased in the amount of R$295.3 million, through the issuance of 6,282,660 preferred shares at the issue price of R$47.00 per unit, increasing the share capital of the Company to R$53.9 billion, represented by 503,046,911 common shares and 985,019,821 preferred shares.

*GVTPar Merger and Increase in the Company's Share Capital*

On May 28, 2015, our shareholders approved the merger of shares issued by GVTPar by the Company and its implementation, with the conversion of GVTPar in a wholly owned subsidiary of the Company and the resulting increase in the Company's capital in the amount of R$9.7 billion through the issue of 68,597,306 common shares and 134,320,885 preferred shares, all without par value, increasing the share capital of the Company to R$63.6 billion, as it stands at the date of this report.

*Conversion of Our Preferred Shares into Common Shares*

As mentioned above, on October 1, 2020, our shareholders approved, and our preferred shareholders ratified, the conversion of all the preferred shares issued by the Company into common shares, in the proportion of one (1) common share for each one (1) preferred share and its implementation by the Company's officers as well as the relevant changes to the Company's bylaws to reflect the Conversion.

After the concession and the expiration of the term for shareholders to exercise withdrawal rights, we proceeded with the Conversion, and the last trading session for our preferred shares on the B3 and for our ADSs backed by preferred shares on the NYSE was on November 20, 2020. Therefore, as of November 23, 2020, "VIVT3" represents the only ticker symbol for trading of the Company's common shares on the B3, and ADSs backed by our common shares began trading on the NYSE under the ticker symbol "VIV."

[**Table of Contents**](#TOC)

The Conversion was undertaken as part of certain improvements to our Corporate Governance Practices, in order to maximize the generation of value to all our shareholders, conferring to them rights set forth under Brazilian Corporate Law, such as the right to vote and the right to tag along, among others.

***Board of Directors***

Under our bylaws, any matters subject to the approval of our Board of Directors can be approved only by the majority of votes of the present members of our Board of Directors. Under our bylaws, our board of directors may only deliberate if a majority of its members currently in office are present at a duly convened meeting and in the event of a tie, the Chairman of the board of directors shall be the tiebreaker.

*Election of Directors*

The members of our Board of Directors are elected at shareholders' meetings for three-year terms. The tenure of the members of the Board of Directors and of the Board of Executive Officers will be conditioned on such members signing the respective instrument of investiture and complying with applicable legal requirements.

*Qualification of Executive Officers and Directors*

Recent changes to the Brazilian Corporate Law have removed the requirement that executive officers must be residents of Brazil. Now, our executive officers and the members of our Board of Directors are not required to be residents of Brazil; however, their tenure is conditioned on the appointment of a representative who resides in Brazil with powers to, for at least three years after the termination of the term of office, to (i) receive service of process in proceedings initiated against such member based on the corporate legislation; and (ii) receive service of process and subpoenas in administrative proceedings initiated by the CVM when holding a management position in a publicly-held company.

*Fiduciary Duties and Conflicts of Interest*

All members of our board of directors owe fiduciary duties to us and all of our shareholders.

Under the Brazilian Corporate Law and the board of directors' internal rules, if one of our directors has a conflict of interest with our Company in connection with any proposed transaction, such director may not vote on any decision of our board of directors regarding such transaction and must disclose the nature and extent of his conflicting interest for inclusion in the minutes of the applicable meeting. The same rules on conflict of interest rules are applicable to executive officers.

Any transaction in which one of our Directors or Executive Officers may have an interest can only be approved on reasonable and fair terms and conditions that are no more favorable than the terms and conditions prevailing in the market or offered by third parties. If any such transaction does not meet this requirement, then the Brazilian Corporate Law provides that the transaction may be held null and void and the interested director or executive officer must return to us any benefits or other advantages that he obtained from, or as result of, such transaction. Under the Brazilian Corporate Law and upon the request of a shareholder who owns at least 1% (as reduced by CVM Resolution No. 70/2022) of our total share capital, our Directors and Executive Officers must disclose to our shareholders at the Annual Shareholders' Meeting certain transactions and circumstances that may give rise to a conflict of interest. In addition, our Company (through the approval of the majority of our share capital) or shareholders who own 1% (as reduced by CVM Resolution No. 70/2022) or more of our share capital may bring an action for civil liability against any Director and/or Executive Officers for any losses caused to us as a result of a conflict of interest.

***Compensation***

Under our bylaws, our common shareholders approve the annual cap for aggregate compensation payable to our Directors, Executive Officers and members of our Fiscal Board. Subject to this approval, our Board of Directors establishes the distribution of such compensation of its members and of our executive officers.

As per Brazilian Corporate Law, the compensation payable to the members of the fiscal board shall not be less than 10% of the compensation of the company's executive officers, not including other benefits listed in paragraph three of article 162 thereof.

[**Table of Contents**](#TOC)

*Mandatory Retirement*

Neither the Brazilian Corporate Law nor our bylaws establish a mandatory retirement age for our directors or executive officers.

***Share Capital***

Each of our common shares entitles its holder to one vote at our annual and extraordinary shareholders' meetings. Holders of our common shares are not entitled to any preference in respect of our dividends or other distributions or otherwise in case of our liquidation.

***Shareholders' Meetings***

Under the Brazilian Corporate Law, we must hold an annual shareholders' meeting by April 30 of each year in order to:

● approve or reject the financial statements approved by our board of directors, including any recommendation by our Board of Directors for the allocation of net profit and distribution of dividends; and

● elect members of our Board of Directors (upon expiration of their three-year terms) and members of our Fiscal Board (every year), subject to the right of minority common shareholders to elect members of our board of directors and our fiscal board.

In addition to the annual shareholders' meetings, holders of our common shares have the power to determine any matters related to changes in our corporate purposes and to pass any resolutions they deem necessary to protect and enhance our development whenever our interests so require, by means of extraordinary shareholders' meetings.

We convene our shareholders' meetings, including our annual shareholders' meeting, by publishing a notice in a Brazilian major newspaper. On the first call of a shareholders' meeting, the notice must be published no fewer than three (3) times, beginning, the first notice, at least twenty-one (21) calendar days prior to the scheduled meeting date. On the second call of a shareholders' meeting, the notice must be published no fewer than three (3) times, beginning at least eight (8) calendar days prior to the scheduled meeting date. In accordance with our bylaws, for meetings involving deliberations described under article 136 of the Brazilian Corporate Law, the notice must be published at least thirty (30) calendar days prior to the scheduled meeting date and on the second call at least ten (10) calendar days prior to the scheduled meeting date. As recommended by the CVM, for annual shareholders' meetings, we convene our shareholders' meeting thirty (30) calendar days prior to the scheduled meeting date. The notice must contain the meeting's place, date, time, agenda and, in the case of a proposed amendment to our bylaws, a description of the subject matter of the proposed amendment.

Our Board of Directors may convene shareholders' meetings. Under the Brazilian Corporate Law, shareholders' meetings also may be convened by our shareholders as follows:

● by any of our shareholders if, under certain circumstances set forth in the Brazilian Corporate Law, our Directors do not convene a shareholders' meeting required by law within sixty (60) days; and

● by shareholders holding at least 1% (as reduced by CVM Resolution No. 70/2022) of our total share capital if, after a period of eight (8) days, our Directors fail to call a shareholders' meeting that has been requested by such shareholders by means of a duly reasoned request that indicates the subject matter.

In addition, our Fiscal Board may convene an ordinary shareholders' meeting if our Board of Directors does not convene an annual shareholders' meeting within thirty (30) days or an extraordinary shareholders' meeting at any other time to consider any urgent and serious matters.

Each shareholders' meeting is presided over by the president of the Board of Directors, who is responsible for choosing a secretary of the meeting among those present at the meeting. In case of absence of the president of the Board of Directors at the shareholders' meeting, the shareholders may choose, among those present, the president and the secretary of the meeting. A shareholder may be represented at a shareholders' meeting by an attorney-in-fact appointed by the shareholder less than one (1) year before the meeting. The attorney-in-fact must be a shareholder, a member of our Board of Directors, a member of our Board of Executive Officers, a lawyer or a financial institution, and the representation of the condominium members shall be made by the manager of the investment fund. The power of attorney appointing the attorney-in-fact must comply with certain formalities set forth

[**Table of Contents**](#TOC)

under Brazilian law. To be admitted to a shareholders' meeting, a person must produce proof of his or her shareholder status and/or a valid power of attorney (if the shareholder is to be represented by an attorney-in-fact), together with any other requirement provided for in the call notice.

In order to convene a shareholders' meeting, shareholders representing at least 25% (except when the agenda sets forth a matter that requires a higher quorum) of our issued voting share capital must be present on the first call. However, shareholders representing at least two-thirds of our issued voting share capital must be present at a shareholders' meeting called to amend our bylaws. If a quorum is not met, our Board of Directors may issue a second call by publishing a notice as described above at least eight (8) calendar days prior to the scheduled meeting. Except as otherwise provided by law, the quorum requirements do not apply to a meeting held on the second call, and the shareholders' meetings may be convened with the presence of shareholders representing any number of shares (subject to the voting requirements for certain matters described below).

***Remote Voting***

Pursuant to the CVM Resolution No. 81/2022, as amended, the system of Remote Voting is required to be adopted by Brazilian companies for: (i) an Ordinary General Shareholders' Meeting; (ii) whenever an Extraordinary General Shareholders' Meeting is called and occurs on the same date as an Ordinary General Shareholders' Meeting; and (iii) whenever a Shareholders' Meeting is called to elect the members of the fiscal board or of the board of directors, due to the requirements set forth in article 26, paragraph 1, item II of CVM Resolution No. 81/2022 (Remote Voting can be adopted in other situations, at the Company's choice). This system aims to facilitate the participation of the Company's shareholders in its meetings. This resolution provides for the following:

● the creation of a Remote Voting Ballot (*Boletim de Voto a Distância*) through which the shareholders may exercise their right to vote prior to the date in which the shareholders' meeting is held;

● the possibility to include in the Remote Voting Ballot a list of candidates and submit minority shareholders' proposals, for deliberation at the shareholders' meeting, upon satisfaction of certain criteria;

● the deadlines, procedures and means of transmitting the Remote Voting Bulletin; and

● the possibility of holding shareholders' meeting by fully digital means (in which case shareholders may only participate virtually) or partially digital means (in which case shareholders may either participate virtually or attend the meeting in person at the Company's headquarters).

In addition, listed companies are required to adopt certain measures regarding the voting process, including:

● informing the market of the adoption of the cumulative voting process in shareholders' meetings immediately upon receipt of the first valid requirement; and

● disclosing voting maps, as well as any voting statement presented by a shareholder at a meeting;

In accordance with the provisions of applicable laws and regulations, the Company has adopted the Remote Voting System since its Annual Shareholders' Meeting held on April 26, 2017.

We do not have an electronic system for receiving Remote Voting Ballot or remote participation ballots. Exceptionally, we may hold meetings partially or exclusively through a digital format, in accordance with CVM Resolution No. 81/2022. Specific instructions regarding remote voting in shareholders' meetings, which we may decide to hold partially or exclusively through a digital format, will be disclosed in the relevant shareholders' meeting manual, in addition to other channels that we may deem appropriate.

***Voting Rights***

Under the Brazilian Corporate Law and our bylaws, each of our common shares entitles its holder to one vote at our shareholders' meetings. There are no limitations under the Brazilian Corporate Law or our bylaws on the right of non-Brazilian residents or nationals to own shares or vote according to those shares, other than the restrictions applicable to all shareholders.

[**Table of Contents**](#TOC)

*Voting Rights of Common Shares*

Except as otherwise provided by law, resolutions of a shareholders' meeting are passed by a simple majority vote of the holders of our common shares present or represented at the meeting, without taking abstentions into account. Under the Brazilian Corporate Law, the approval of shareholders representing at least half of our voting shares, if a higher quorum is not required by our bylaws, is required for the types of action described below:

● creating preferred shares or disproportionately increasing an existing class of our preferred shares relative to the other classes of our preferred shares, other than to the extent permitted by our bylaws;

● changing a preference, privilege and condition of redemption or amortization of any class of the company`s preferred shares or creating a new class of shares that is more privileged;

● reducing the mandatory dividend;

● merging or consolidating the company with another company;

● participating in a centralized group of companies (grupo de sociedades) as defined under the Brazilian Corporate Law and subject to the conditions set forth in the Brazilian Corporate Law;

● acquisition of all the company's shares by another company, known as an "incorporação de ações" under the Brazilian Corporate Law;

● changing the company's corporate purpose;

● canceling any ongoing liquidation of the company;

● creation of participation certificates;

● spinning-off of all or any part of the company; and

● dissolution of the company.

As per Brazilian Corporate Law, the decisions on the transformation of the company into another form of business entity require the unanimous approval of our shareholders, unless provided for in the company by-laws.

Our Company is required to give effect to shareholders agreements that contain provisions regarding the purchase or sale of our shares, preemptive rights to acquire our shares, the exercise of the right to vote or the power to control our Company, if these agreements are filed with our headquarters. Brazilian Corporate Law requires the president of any Shareholder's or Board of Directors meeting to disregard any vote taken by any of the parties to said agreement that have been duly filed with our Company in violation of the provisions of any such agreement. In the event that a shareholder that is party to a shareholders agreement (or a director appointed by such shareholder) is absent from any shareholders' or Board of Directors' meeting or abstains from voting, the other party or parties to that shareholders agreement have the right to vote the shares of the absent or abstaining shareholder (or on behalf of the absent director) in compliance with that shareholders agreement.

For the effective implementation of the Conversion, a voting agreement was executed on October 1, 2020 by and among the shareholders Telefónica S.A., Telefónica LATAM, SP Telecom, and, as intervening and consenting party, the Company, in order to comply with the provisions of ANATEL regulations. This voting agreement was filed and made available at our Company headquarters, as determined under article 118 of Brazilian Corporate Law (the "Voting Agreement").

However, on October 31, 2022, the Company informed the market and its shareholders that the Voting Agreement lost its purpose and effectiveness as a result of the liquidation and extinction of SP Telecom that took place on that date, given that its purpose consisted of maintaining the exercise of direct control power of the Company by SP Telecom.

[**Table of Contents**](#TOC)

The shares issued by the Company and held by SP Telecom. ("Shares") were delivered to its partners Telefónica S.A. and Telefónica LATAM, in the proportion of their respective participation in the social capital of SP Telecom, within the scope of the sharing of shareholders' equity.

The Company informed the market that the liquidation of SP Telecom, the consequent termination of the Voting Agreement and the aforementioned delivery of SP Telecom's shares did not result in a change in the composition of the Company's control (which was already indirectly held jointly by Telefónica S.A., Telefónica LATAM and SP Telecom, all companies under common control with Telefónica S.A.), its administrative structure or its regular operation.

Under the Brazilian Corporate Law, neither our bylaws nor actions taken at a shareholders' meeting may deprive any of our shareholders of certain specific rights, including:

● the right to participate in the distribution of our profits;

● the right to participate in any remaining residual assets in the event of our liquidation;

● the right to supervise the management of our corporate business subject to the conditions set forth in the Brazilian Corporate Law;

● preemptive rights in the event of an issuance of our shares, debentures convertible into our shares or subscription bonuses, except with respect to a public offering of our securities; and

● the right to withdraw from our Company subject to the conditions set forth in the Brazilian Corporate Law.

*Voting Rights of Minority Shareholders*

Shareholders holding shares representing not less than 5% of our voting shares at our shareholders' meeting have the right to request that we adopt, even if not foreseen in ou bylaws, a cumulative voting procedure to elect the members of the Board of Directors. This procedure must be requested by the required number of shareholders at least 48 hours prior to a shareholders' meeting.

Under the Brazilian Corporate Law, shareholders that are not controlling shareholders, but that together hold common shares representing at least 15% of our voting capital have the right to appoint one member and their alternate to our Board of Directors at our shareholders' meeting. However, CVM has already issued several decisions determining that, in cases where the company has issued only shares with voting rights, such as the Company, the percentage to be considered for the appointment of the member of the Board of Directors by the non-controlling shareholders shall be reduced to 10% of the total of common shares.

In the event that minority holders of common shares elect a director and the cumulative voting procedures described above is also used, our controlling shareholders always retain the right to elect at least one member more than the number of members elected by the other shareholders, regardless of the total number of members of our Board of Directors.

The shareholders seeking to exercise these minority rights (except for the cumulative voting procedure) must prove that they have held their shares for no less than three months preceding the shareholders' meeting at which the director will be appointed. Brazilian Corporate Law provides that any directors appointed by the non-controlling shareholders have the right to veto for cause the selection of our independent registered public accounting firm.

In accordance with the Brazilian Corporate Law, minority shareholders are entitled to elect one member and an alternate to our Fiscal Board in a separate election as long as they jointly represent 10% or more of the voting shares. The other shareholders with the right to vote may elect the remaining members and alternates, who, in any event, must outnumber the directors and alternates elected by minority common shareholders.

[**Table of Contents**](#TOC)

Under the Brazilian Corporate Law, the following actions require the previous approval of or the ratification by the majority of issued and outstanding shares of the affected class within one year from the shareholders' meeting at which the common shareholders approve the action:

● the creation of preferred shares or a disproportionate increase of an existing class of preferred shares relative to the other classes of preferred shares, other than to the extent permitted by our bylaws;

● a change of a priority, preference, right, privilege or condition of redemption or amortization of any class of preferred shares; or

● the creation of a new class of preferred shares that has a priority, preference, right, condition or redemption or amortization superior to an existing class of preferred shares.

This meeting would be called by publication of a notice in two Brazilian newspapers for three days, at least 30 days before the meeting, in accordance with our bylaws.

***Liquidation***

We may be liquidated in accordance with the provisions of Brazilian law. In the event of our extrajudicial liquidation, a shareholders' meeting will determine the manner of our liquidation, appoint our liquidator and our Fiscal Board that will function during the liquidation period.

***Preemptive Rights***

Each shareholder has a general preemptive right to subscribe for shares of the same class in any capital increase, in an amount sufficient to keep the same proportional participation of such shareholder in the total capital of the corporation. A minimum period of thirty (30) days following the publication of the capital increase notice shall be observed by the corporation for the exercise of the preemptive right by the shareholder. The right of participation in capital increases is assignable under Brazilian Corporate Law. In the event of a capital increase that would maintain or increase the proportion of capital represented by common shares, holders of ADSs, or of common shares, would have the preemptive right to subscribe only to our newly issued common shares. In the event of a capital increase that would reduce the proportion of capital represented by common shares, holders of ADSs, or of common shares, would have the preemptive right to subscribe to our newly issued common shares in proportion to their shareholdings and to our newly issued common shares only to the extent necessary to prevent dilution of their interest.

However, holders of our ADSs may not be able to exercise the preemptive rights relating to our common shares underlying their ADSs unless a registration statement under the Securities Act is effective with respect to those rights or an exemption from the registration requirements of the Securities Act is available. We are not obligated to file a registration statement with respect to the shares relating to these preemptive rights or to take any other action to make preemptive rights available to holders of our ADSs, and we may not file any such registration statement.

In addition, a publicly held company whose bylaws allow for capital increases may provide for the issuance of stock, debentures convertible into stock or subscription bonuses without granting any preemptive rights to prior shareholders or by decreasing the term for the shareholders to exercise their preemptive rights, as long as the placement of such securities is made:

● upon a sale on a stock exchange or public subscription;

● through an exchange of shares in a public offering, with the purpose of acquiring control of another company as specified in the Brazilian Corporate Law; or

● for the use of certain tax incentives but only when such placement is made without granting preemptive rights.

***Redemption, Amortization, Tender Offers and Rights of Withdrawal***

Our bylaws or our shareholders at a shareholders' meeting may authorize us to use our profits or reserves to redeem or amortize our shares in accordance with conditions and procedures established for such redemption or amortization. The Brazilian Corporate Law defines "redemption" (*resgate de ações*) as the payment of the value of the shares in order to permanently remove such shares from circulation, with or without a corresponding reduction of our share capital. However, if the same share capital is maintained, the Company shall attribute a new par value for the remaining shares. The Brazilian Corporate Law defines "amortization" (*amortização*) as the distribution to the shareholders, without a corresponding capital reduction, of amounts that they would otherwise receive if we were liquidated. If an amortization distribution has been paid prior to our liquidation, then upon our liquidation, the shareholders who did not receive an amortization distribution will have a preference equal to the amount of the amortization distribution in the distribution of our capital.

The Brazilian Corporate Law authorizes us to redeem shares not held by our controlling shareholders, if, after a tender offer effected as a consequence of a delisting of the Company before the CVM, less than 5% of our outstanding shares remains publicly-held. The redemption price in such case would be the same price paid for our shares in such tender offer.

The Brazilian Corporate Law also require the acquirer of control (in case of a change of control) or the controller (in case of delisting or a substantial reduction in liquidity of our shares) to make a tender offer for the acquisition of the shares held by minority shareholders under certain circumstances described below under "—Mandatory Tender Offers." The shareholder can also withdraw its capital from our Company under certain circumstances described below under "—Rights of Withdrawal."

*Mandatory Tender Offers*

The Brazilian Corporate Law requires the launching of a tender offer at a purchase price equal to the fair value for all outstanding shares in order to cancel (or to convert) the registration of our company as a publicly held company or in case of a substantial reduction in the liquidity of our shares as a result of purchases by our controlling shareholders. If our controlling shareholders enter into a transaction which results in a change of control of our company, the controlling shareholders must include in the documentation of the transaction an obligation of the acquirer to launch a tender offer for the purchase of all our common shares for, at least, 80% of the price per share paid to the controlling shareholders. The tender offer must be submitted to the CVM within 30 days from the date of execution of the definitive documents of sale of the shares.

*Rights of Withdrawal*

The Brazilian Corporate Law provides that, in certain limited circumstances, a dissenting shareholder may withdraw its equity interest from our company and be reimbursed by us for the value of our common shares that it then holds.

This right of withdrawal may be exercised by dissenting shareholders in the event that the holders of shares with voting rights authorize:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) creating preferred shares or disproportionately increasing any existing class of preferred shares relative to the other classes of preferred shares, other than to the extent permitted by our bylaws;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) changing a priority, preference, right, privilege or condition of redemption or amortization of any class of preferred shares or creating a new class of shares that is more privileged;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) reducing the mandatory dividend;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) a change in our corporate purpose;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) merging or consolidating our Company, with another company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) the acquisition of all of our shares by another company, known as an "incorporação de ações" under the Brazilian Corporate Law;

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) participating in a centralized group of companies (grupo de sociedades) as defined under the Brazilian Corporate Law and subject to the conditions set forth in the Brazilian Corporate Law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii)spinning-off of all or any part of our Company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix) the inclusion of an arbitration clause in our bylaws.

In addition, we note that:

● in items (i) and (ii), only the holders of shares of the affected type or class will be entitled to redemption;

● in items (v) to (vii), the holders of shares of a type or class with liquidity and dispersion (as defined in CVM Resolution 78/2022) in the market will not have the right to redemption considering the conditions set forth in the Brazilian Corporate Law; and

● in item (viii), the dissenting shareholders shall only have a right of redemption if the spinning off implies in: (1) a change in the corporate purpose (except if the spun-off assets revert to a company whose main purpose is the same as ours), (2) a reduction of the mandatory dividend, or (3) participation in a group of companies.

Dissenting shareholders are also entitled to withdraw in the event that the entity resulting from a merger or spin-off does not have its shares listed in an exchange or traded in the secondary market within one hundred and twenty (120) days from the shareholders' meeting that approved the relevant merger or spin-off.

Notwithstanding the above, in the event that we are consolidated or merged with another company, become part of a centralized group of companies, or acquire the control of another company for a price in excess of certain limits imposed by the Brazilian Corporate Law, holders of any type or class of our shares or the shares of the resulting entity that have minimal market liquidity and are dispersed among a sufficient number of shareholders will not have the right to withdraw. For this purpose, shares that are part of general indices representative of portfolios of securities traded in Brazil (as defined by CVM Resolution 78/2022) or abroad are considered liquid, and sufficient dispersion will exist if the controlling shareholder, the parent company or other companies under its control hold less than half of the total number of outstanding shares of that type or class.

Only shareholders who own shares on the date of publication of the first notice convening the relevant shareholders' meeting or the press release concerning the relevant transaction is published, whichever is earlier, will be entitled to withdrawal rights.

The redemption of shares arising out of the exercise of any withdrawal rights would be made at the book value per share, determined on the basis of our most recent audited balance sheet approved by our shareholders. If the shareholders' meeting approving the action that gave rise to withdrawal rights occurred more than sixty (60) days after the date of the most recent approved audited balance sheet, a shareholder may demand that its shares be valued on the basis of a balance sheet prepared specifically for this purpose. In this case the company shall pay immediately 80% of the redemption value calculated based on the last balance sheet and, having drawn up the necessary balance sheet, will pay the remaining amount within one hundred and twenty (120) days from the date of the resolution of the shareholders' meeting.

The right of withdrawal lapses thirty (30) days after the date of publication of the minutes of the shareholders' meeting that approved the action that gave rise to withdrawal rights. Within ten days following the expiration of the term to exercise the withdrawal rights mentioned above, the company may call a Shareholders' Meeting to confirm or reconsider any resolution giving rise to withdrawal if we believe that the withdrawal of shares of dissenting shareholders would jeopardize its financial stability.

***Liability of Our Shareholders for Further Capital Calls***

Neither Brazilian law nor our bylaws require any capital calls. Our shareholders' liability for capital calls is limited to the payment of the issue price of any shares subscribed or acquired.

[**Table of Contents**](#TOC)

***Inspection of Corporate Records***

Shareholders that own 1% (as reduced by CVM Resolution 70/2022) or more of our outstanding share capital have the right to inspect our corporate records, including shareholders' lists, corporate minutes, financial records and other documents of our company, if (1) any acts contrary to Brazilian law or the company's bylaws have been committed, or (2) there are grounds to suspect that there are material irregularities in our company. However, in either case, the shareholder that desires to inspect our corporate records must obtain a court order authorizing the inspection.

***Disclosures of Share Ownership***

Brazilian regulations require that (1) each of our controlling shareholders, directly or indirectly, (2) shareholders who have elected members of our Board of Directors or Fiscal Board, and (3) any person or group of persons representing a person that has directly or indirectly acquired or sold a material interest in our shares of any type and class disclose its or their share ownership or divestment to us, and we are responsible for transmitting such information to the CVM and the market. In addition, if a share acquisition results in, or is made with the intention of, change of control or company's management structure, as well as acquisitions that cause the obligation of performing a tender offer, the persons acquiring such number of shares are required to publish a statement containing certain required information about such acquisition in the same channels the Company typically uses.

CVM defines a "material interest" deal as any increase or decrease in share ownership of any class resulting in a change in the *ownership levels* of our shareholders. The ownership levels are set in 5% increments (for example, an acquisition where the total ownership of a shareholder jumps from 9% to 11% should be reported since it made the ownership surpass the 10% level). Ownership levels are calculated adding direct and indirect ownership and derivatives based upon our shares.

Our controlling shareholders, shareholders that appoint members of our Board of Directors or Fiscal Board and members of our Board of Directors, Board of Executive Officers or Fiscal Board must file a statement reporting any change in their holdings of our shares, or of any family member or person included as dependent in their income tax return, or of our controlling shareholders (only if they are considered public companies), with the CVM and the Brazilian stock exchanges on which our securities are traded.

***Form and Transfer***

Our common shares are in book-entry form, registered in the name of each shareholder or its nominee. The transfer of our shares is governed by article 35 of the Brazilian Corporate Law, which provides that a transfer of shares is effected by our transfer agent by an entry made by the transfer agent in its books, upon presentation of valid written share transfer instructions to us by a transferor or its representative. When common shares are acquired or sold on a Brazilian stock exchange, their transfer is effected on the records of our transfer agent by a representative of a brokerage firm or the stock exchange's clearing system. The transfer agent also performs all the services of safe-keeping of our shares. Transfers of our shares by a non-Brazilian investor are made in the same manner and are executed on the investor's behalf by the investor's local agent. If the original investment was registered with the Central Bank pursuant to foreign investment regulations, the non-Brazilian investor is also required to amend, if necessary, through its local agent, the electronic certificate of registration to reflect the new ownership.

The B3 operates a central clearing system. A holder of our shares may choose, at its discretion, to participate in this system, and all shares that such shareholder elects to be put into the clearing system are deposited in custody with the clearing and settlement chamber of the B3 (through a Brazilian institution that is duly authorized to operate by the Central Bank and maintains a clearing account with the clearing and settlement chamber of the B3). Shares subject to the custody of the clearing and settlement chamber of the B3 are noted as such in our registry of shareholders. Each participating shareholder will, in turn, be registered in the register of the clearing and settlement chamber of the B3 and will be treated in the same manner as shareholders registered in our books.

**Dividends**

Brazilian Corporate Law also states that declared dividends must be paid until the end of the fiscal year in which it was declared. Under article 9 of Law 9,249/95 and our bylaws, we also may pay interest attributable to shareholders' equity as an alternative form of dividends upon approval of our board of directors.

[**Table of Contents**](#TOC)

***Payment of Dividends and Interest on Shareholders' Equity***

We may pay the mandatory distributable amount as dividends or as interest attributable to shareholders' equity, which is similar to a dividend but is deductible in calculating our income tax obligations.

The common shares underlying our ADSs are held in Brazil by the depositary, which has registered with the Central Bank as the registered owner of our common shares. Payments of cash dividends and distributions, if any, will be made in Brazilian currency to the depositary. The depositary will then convert such proceeds into U.S. dollars and will cause such U.S. dollars to be distributed to holders of our ADSs. As with other types of remittances from Brazil, the Brazilian government may impose temporary restrictions on remittances to foreign investors of the proceeds of their investments in Brazil, as it did for approximately six months in 1989 and early 1999, and on the conversion of Brazilian currency into foreign currencies, which could hinder or prevent the depositary from converting dividends into U.S. dollars and remitting these U.S. dollars abroad.

In addition, remittances are subject to a Brazilian financial transactions tax, which as of the date of this annual report is zero, but may be subject to change.

For information about taxation on profits, dividends and interest on shareholders' equity, see "Item 10. Additional Information—E. Taxation—Brazilian Tax Considerations—Taxation of Dividends" of this Form 20-F.

*Dividends*

We are required by the Brazilian Corporate Law and by our bylaws to hold an annual shareholders' meeting until April 30 of each year. At our annual shareholders' meeting, our common shareholders may vote to declare an annual dividend. Our payment of annual dividends is based on our audited financial statements prepared for our preceding fiscal year.

Any holder of record of shares at the time that a dividend is declared is entitled to receive dividends. Under the Brazilian Corporate Law, we are generally required to pay dividends within 60 days after declaring them, unless the shareholders' resolution establishes another payment date, which, in any case, must occur prior to the end of the fiscal year in which the dividends were declared.

Our Board of Directors may declare interim dividends based on (i) the accrued profits recorded in our semiannual financial statements; (ii) the accrued profits recorded in our quarterly financial statements or in our financial statements for shorter periods, provided that the total amount of dividends paid up every six months does not exceed the total amount within the capital reserve determined pursuant to article 182 of the Brazilian Corporate Law; and (iii) the amount recorded in the profit and loss account or profit reserve account in our last annual or semiannual financial statements.

All the interim dividends that are distributed shall be considered as part of the mandatory dividends that shall be paid by us.

*Interest on Shareholders' Equity*

Brazilian corporations may make payments to shareholders characterized as interest on shareholders' equity as an alternative form of making dividend distributions. Amounts paid as interest on shareholders' equity (net of applicable withholding tax, as described below) may be deducted from the minimum dividends we are obligated to distribute to our shareholders in accordance with our bylaws and Brazilian Corporate Law. The rate of interest may not be higher than the federal government's TJLP, as determined by the Central Bank from time to time (7.5% per annum for 2016 and for the first quarter of 2017, 7.0% for the remaining quarters of 2017, 6.75%, 6.6%, 6.56% and 6.98% for the four quarters of 2018, and 7.03%, 6.26%, 5.95% and 5.57% for the four quarters of 2019, and 5.09%, 4.94%, 4.91% and 4.55% for the four quarters of 2020, and 4.39%, 4.61%, 4.88% and 5.32% for the four quarters of 2021, and 6,08%, 6,82%, 7,01% and 7,20% for the four quarters of 2022), applied over specific net equity accounts. The total amount distributed as interest on shareholders' equity may not exceed the greater of (i) 50% of net income (before taking the distribution and any deductions for income taxes into account) for the year with respect to which the payment is made and (ii) 50% of retained earnings for the year before that in which the payment is made. Payments of interest on shareholders' equity are decided by the shareholders on the basis of recommendations of our Board of Directors.

Distributions of interest on shareholders' equity paid to Brazilian and non-Brazilian holders of common shares, including payments to the depositary in respect of common shares underlying ADSs, are deductible by us for Brazilian corporate income tax

[**Table of Contents**](#TOC)

purposes. These payments to U.S. holders or other non-Brazilian holders are subject to Brazilian withholding tax at the rate of 15%. If the recipient of the payment is domiciled in a Tax Haven Jurisdiction, as defined by Brazilian law, the rate will be 25%.

*Time Limits for Claiming Dividends*

Our shareholders have three (3) years to claim dividend distributions made with respect to their shares, as from the date that we distribute the dividends to our shareholders, after which any unclaimed dividend distributions legally revert to us. We are not required to adjust the amount of any distributions for inflation that occurs during the period from the date of declaration to the payment date.

**C.** Material Contracts

On June 30, 2011, ANATEL renewed our STFC concession contract and consolidated them into two new contracts (each filed as an Exhibit to this annual report). One of these contracts authorizes the Company to provide local telephone service (to the cities in Sector 31) and the other contract authorizes the Company to provide long-distance telephone service (to and from Sector 31). These concession contracts will expire on December 31, 2025.

We also have an authorization to provide local and long-distance telephone services under the private system (all sectors, except Sector 31, which is the area of concession), granted in 2002, for an unlimited term. We also hold multimedia communication service authorization terms, which are also material contracts. Based on these authorization terms, we may provide broadband services in the state of São Paulo and all over Brazilian territory. The terms were signed on April 17, 2003 and March 19, 2004 for an unlimited term and are still in effect. We also have conditioned access service authorization terms for the provision of Pay TV services. The authorization terms were transferred back to us in 2013, as a result of a corporate restructuring.

As regards mobile services, the PGA divided the country into three regions: Region I: states of Rio de Janeiro, Espírito Santo, Minas Gerais, Amazonas, Roraima, Amapá, Pará, Maranhão, Bahia, Sergipe, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco and Alagoas, Region II: states of Paraná, Santa Catarina, Rio Grande do Sul, Goiás, Tocantins, Mato Grosso do Sul, Mato Grosso, Rondônia, Acre and Federal District and Region III: only the state of São Paulo.

We received authorization terms for the provision of SMP services with national coverage, in all three regions. Licenses for SMP services rant the right to provide mobile services for an unlimited term. However, the use of radiofrequency spectrum is restricted in accordance with specific license conditions, as follows:

● Rio Grande do Sul, excluding the cities of Pelotas, Capão do Leão, Morro Redondo and Turuçu ("A" band) until 2028 (renewed in 2022);

● Rio de Janeiro ("A" band) until 2028 (renewed in 2020);

● Espírito Santo ("A" band) until 2023 (renewed in 2008);

● Bahia ("A" band) and Sergipe ("A" band) until 2023 (renewed in 2008);

● São Paulo ("A" band) until 2023 (renewed in 2008); and until 2024, for the cities of Ribeirão Preto and Guatapará (renewed in 2009);

● Paraná/Santa Catarina ("B" band) until 2028 (renewed in 2013);

● Distrito Federal ("A" band) until 2028 (renewed in 2021);

● Acre ("A" band), Vivo-Rondônia ("A" band), Mato Grosso ("A" band) and Mato Grosso do Sul ("A" band) until 2024 (renewed in 2009);

● Goiás/Tocantins ("A" band) until 2023 (renewed in 2008);

● Amazonas/Roraima/Amapá/Pará/Maranhão ("B" band) until 2028 (renewed in 2014);

[**Table of Contents**](#TOC)

● Minas Gerais ("A" band) until 2023 (renewed in 2008); and

● For the cities in which CTBC Telecom operates in the state of Minas Gerais ("E" band) until 2020 (to be renewed between the period of April 28, 2016 and April 28, 2017).

License renewals for "A" and "B" bands must be requested within 30 months from the expiry date. Currently, according to Decree No. 10,402/2020, which regulates the New General Telecommunications Law, it is possible to renew licenses for successive periods. Nevertheless, some conditions are being discussed with ANATEL, such as the associated renewal valuation. License renewals for the "E" band must be requested between 36 and 48 months in advance of the expiry date.

In December 2007, ANATEL auctioned off nationally 15 blocks in the 1,900 MHz band ("L" band). We won 13 of them throughout Brazil, except in the northern region and the towns of Londrina and Tamarana in the state of Paraná. Nevertheless, the bidding terms set forth the possibility of realigning the "L" band with the "J" band, maintaining the same conditions (including costs and expiry date) of the "J" band. In 2012, Telefônica requested and on August 27, 2013, ANATEL granted the "L" band realignment for the following states:

● Rio Grande do Sul, excluding the cities of Pelotas, Morro Redondo, Capão do Leão e Turuçu;

● Rio de Janeiro;

● Espírito Santo;

● Bahia and Sergipe;

● Telefônica-São Paulo, excluding the cities of Altinópolis, Aramina, Batatais, Brodosqui, Buritizal, Cajuru, Cássia dos Coqueiros, Colômbia, Franca, Guaíra, Guará, Ipuã, Ituverava, Jardinópolis, Miguelópolis, Morro Agudo, Nuporanga, Orlândia, Ribeirão Corrente, Sales de Oliveira, Santa Cruz da Esperança, Santo Antônio da Alegria e São Joaquim da Barra;

● Federal District;

● Telefônica-Acre, Vivo-Rondônia, Vivo-Mato Grosso and Vivo-Mato Grosso do Sul excluding the city of Paranaíba; and

● Telefônica-Goiás/Tocantins.

The complete realignment (including the cities excluded above and the States of Alagoas, Ceará, Paraíba, Piauí, Pernambuco and Rio Grande do Norte) was signed on November 30, 2018.

In April 2008, ANATEL auctioned off 36 blocks in the 2,100 MHz band (3G licenses). We obtained nine in the "J" band throughout Brazil, enabling it to provide nationwide coverage in 3G. The spectrum licenses, along with the related renewal dates, are:

● Rio Grande do Sul (including the cities of Pelotas, Morro Redondo, Capão do Leão e Turuçu) ("J" band) until 2023 (to be renewed between the period of April 30, 2019 and April 30, 2020);

● Rio de Janeiro ("J" band) until 2023 (to be renewed between the period of April 30, 2019 and April 30, 2020);

● Minas Gerais (including the cities where CTBC Telecom operates in the state of Minas Gerais) ("J" band) until 2023 (to be renewed between the period of April 2019 and April 2020).

License renewals for the "J" band and "realigned L" band were requested between 36 and 48 months in advance of the expiry date. Currently, according to Decree 10,402/2020, which regulates Law 13,879/2019, it is possible to renew licenses for successive periods.

In December 2010, ANATEL auctioned off 169 licenses in the 900 MHz, 1,800 MHz and 2,100 MHz frequencies. We acquired 23 blocks, 14 in 1,800 MHz frequency bands "D," "E," "M" and extension bands, and nine in the 900 MHz extension bands. As a result, we have nationwide coverage in the 1,800 MHz frequency band. The 23 blocks are:

● "M" Band (1,800 MHz) in the Federal District and the States of Paraná, Santa Catarina, Rio Grande do Sul, Goiás, Tocantins, Mato Grosso do Sul, Mato Grosso, Rondônia and Acre;

● Extension of the 1,800 MHz band throughout the state of São Paulo;

Our current 850 MHz authorizations will expire between 2023 and 2028. If legal and regulatory requirements are met, ANATEL has agreed to renew the current authorizations for the use of radio frequencies in bands A and B, on a primary basis, until November 29, 2028. However, the specific conditions for renewal, such as those related to economic valuation criteria and related obligations, were challenged by the affected service providers, including us. After ANATEL rejected complaints presented by the providers, a final disposition of the matter is still pending and will require a decision by the Federal Court of Accounts (TCU).

Furthermore, since our licenses for the 900 MHz and 1,800 MHz band will expire in 2023, their renewal has been requested and a final decision by Anatel is still pending. On August 2022, ANATEL approved the renewal of 900 MHz and 1,800 MHz licenses held by TIM until 2032, which indicates they may proceed in a similar way for Telefônica's authorizations.

In April 2012, ANATEL auctioned off 273 licenses in the 450 MHz, and 2,500 MHz frequencies. We secured one block in 2,500 MHz frequency band "X" (20 + 20 MHz) nationwide, together with the right and obligation to use the 450 MHz frequency band in the States of Alagoas (AL), Ceará (CE), Minas Gerais (MG), Paraíba (PB), Pernambuco (PE), Piauí (PI), Rio Grande do Norte (RN) and Sergipe (SE), as well as the areas identified by the National Codes 13, 14, 15, 16, 17, 18 and 19, in the State of São Paulo (SP). Nonetheless, the commitment to use the 450 MHz band may also be fulfilled by the use of any other frequency range Telefônica already holds. See below the relevant expiration and renewal dates:

● Brazil ("X" Band – 2,500 MHz) until 2027 (associated with SMP service) to be renewed on October 18, 2024;

[**Table of Contents**](#TOC)

● Alagoas, Ceará, Minas Gerais, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, Sergipe (450 MHz). Anatel declared the extinction, by resignation, of Telefônica Brasil's concession in the 450 MHz band, according to Analysis No. 114/2022/VA and Judgement No. 391, of 12/21/2022. We have not yet opened a formal notification;

● Telefônica in the areas identified by the National Codes 13, 14, 15, 16, 17, 18 and 19, in the state of São Paulo (SP), until 2027 (associated to SMP, SCM and STFC services) Anatel declared the extinction, by resignation, of Telefônica Brasil's concession in the 450 MHz band, according to Analysis No. 114/2022/VA and Judgement No. 391, of 12/21/2022. We have not yet opened a formal notification; and

● In September 2014, ANATEL auctioned off six blocks in the 700 MHz frequency. We acquired three blocks resulting in nationwide coverage in the 700 MHz frequency band. The spectrum licenses may be renewed in 2029.

In December 2015, ANATEL auctioned off the remaining spectrum lots in the 1,800 MHz, 1,900 MHz, 2,500 MHz and 3,500 MHz bands, Telefônica acquired seven lots of the 2,500 MHz frequency band. These lots are associated to six different States, five of them the capital cities of the States of São Paulo, Rio de Janeiro, Rio Grande do Sul, Santa Catarina, and Tocantins and one city in the State of Mato Grosso do Sul. Such frequencies will be used for the provision of 4G mobile services. The spectrum license may be renewed in 2030.

The licenses above may be renewed successively; (ii) for an additional term of 15 years; and (iii) upon payment of 2% of our net revenues from usage charges in the applicable region in the previous year. The payment is also due every two years during the extension period.

In November 2021, ANATEL held the largest spectrum auction in its history, which included 4G and, for the first time, 5G blocks, with 700 MHz, 2.3 GHz, 3.5 GHz and 26 GHz lots. On that occasion, we acquired 3.5 GHz and 26 GHz national licenses (100 MHz and 600 MHz bandwidths, respectively). We also won regional 2.3 GHz licenses, with 50 MHz bandwidth in the southeast region of Brazil (except São Paulo state and PGO Sector 3) and 40 MHz bandwidth in São Paulo state and in the north and mid-west regions of Brazil (except PGO Sectors 22 and 25). These acquired licenses, which we purchased for a total of R$4.45 billion, of which R$0.93 billion is related to licenses and the remaining amount related to the obligations ANATEL set forth. The licenses ensure we have the required spectrum to provide 5G services, and are valid for 20 years (renewable under the then-existing legal conditions at the expiration of this term).

***Acquisition of UPI Mobile Assets of the Oi Group***

On April 20, 2022, the closing of the transaction related to the Purchase Agreement for Acquisition of UPI Mobile Assets of Oi Group took place, and we acquired, on such date, all the shares of Garliava RJ Infraestrutura e Redes de Telecomunicações S.A. ("Garliava"), a special purpose company, to which the mobile assets of Oi Group assigned to us had been contributed, in accordance with the segregation plan stated in the Oi Agreement.

Thus we acquired Garliava's shares for an approximate amount of R$5,373 million, having paid, on such day, the amount of R$4,885 million. The remaining amount, equivalent to 10% of the payment made on that date, was withheld and its release is currently subject to certain ongoing discussions regarding price adjustments, as provided for in the Oi Agreement.

Likewise, on such date, we: (i) committed to an additional payment of R$110 million of which R$40 million were paid at that date, subject to the fulfillment of certain targets by Oi; (ii) made a payment of approximately R$148 million for certain transition services to be provided by Oi to Garliava; and (iii) entered into a take-or-pay data transmission capacity agreement, with a net present value of R$179 million, to be paid monthly during a period of 10 years.

The mobile assets of Oi Group finally assigned to us were the following:

● *Clients*: approximately 12.5 million clients, or approximately 30% of UPI Mobile Assets' total customer base as of February 2022, which allocation sought to enhance competition among the Brazilian telecom market operators;

● *Spectrum*: 43 MHz as a national weighted average based on population, or approximately 46% of the UPI Mobile Assets' radio frequencies, which allocation strictly conforms to ANATEL spectrum limits; and

[**Table of Contents**](#TOC)

● *Infrastructure*: agreements for the use of approximately 2,700 mobile access sites, or approximately 19% of the UPI Mobile Assets' total sites.

All commitments assumed were duly submitted to ANATEL and CADE during 2022.

On October 3, 2022, we started the arbitration procedure ("Arbitration") against Oi S.A. – In Judicial Recovery ("Seller") due to the manifest breach by the Seller of certain terms of the Share Purchase and Sale Agreement and Other Covenants executed by us, jointly with TIM S.A. and Claro S.A. ("Buyers"), and the Seller, on January 28, 2021, as amended ("SPA"), after the exchange of notices about the Post-Closing Price Adjustment between Buyers and the Seller, upon the competent request of Arbitration filed with the Market Arbitration Chamber, under the terms of the SPA.

On February 1, 2023, Telefônica Brasil's Extraordinary Shareholders' Meeting was held and decided for Garliava's merger into Telefónica Brasil, being the effects of such merger subject to the prior approval from ANATEL and the conclusion of certain systemic operations. Once such conditions are fulfilled, Telefônica Brasil's Board of Directors will convene a new meeting to verify the accomplishment of such conditions and to give effects to the said merger.

**D.** **Exchange Controls**

There are no restrictions on ownership of common shares by individuals or legal entities domiciled outside of Brazil, provided that they comply with the registration requirements set forth in the applicable regulation enacted by the Central Bank, CMN and the CVM.

The right to convert dividend or interest payments and proceeds from the sale of shares into foreign currency and to remit such amounts outside Brazil is subject to restrictions under foreign investment legislation which generally requires, among other things, the documentary evidence that provides the validity and properly backs the economic grounds of the foreign exchange transaction and that the relevant investment be registered with the Central Bank and the CVM, as applicable. The restrictions on the remittance of foreign capital abroad may hinder or prevent the custodian for the common shares represented by ADSs or holders of common shares from converting dividends, distributions or the proceeds from any sale of these common shares into U.S. dollars and remitting the U.S. dollars abroad if the ADS holder or holder of common shares does not obtain adequate registration, or enough documentation to back the legality of the intended foreign exchange transaction. Holders of ADSs could be adversely affected by delays in, or refusal to grant any, required government approval to convert Brazilian currency payments on the common shares underlying the ADSs and to remit the proceeds abroad. Additionally, considering that the criteria of how much information is needed to back the legality of a foreign exchange transaction is defined by the financial institution liquidating the remittance of funds abroad, holders of ADSs can experience the need to provide different levels of detail and varied information depending on the policies of the chosen financial institution.

As from March 30, 2015, the different forms of foreign portfolio investments in Brazil, including investments via depositary receipts, are regulated by Resolution No. 4,373, and by Law No. 4,131/1962. Law No. 4,131/1962 was recently significantly amended by Law No. 14,286/2021, which came into effect on December 29, 2022 and is regulated by Central Bank of Brazil Resolutions No. 277, 278, 279 and 280, all published on December 31, 2022, which provides, among others, about foreign capital in Brazil, Brazilian capital in foreign countries and the definition of resident and non-resident for purposes of Law No. 14,286/202, as well as by Central Bank Resolution No. 281, also published on December 31, 2022, which establishes in its articles 1 to 6 transitory provisions to be observed regarding foreign capital in Brazil until October 31, 2023, along with the provisions set out in Central Bank Resolution 278 abovementioned.

Resolution No. 4,373 provides for the issuance of Depositary Receipts in foreign markets in respect of shares of Brazilian issuers. The Depositary Receipts program shall be approved by the Central Bank and CVM before the issuance of the Depositary Receipts. Accordingly, the proceeds from the sale of the Depositary Receipts by holders outside Brazil are free of Brazilian foreign investment controls, and holders of the Depositary Receipts may be entitled to favorable tax treatment. See "—E. Taxation—Brazilian Tax Considerations." Under Resolution No. 4,373, foreign investors registered with the CVM may buy and sell Brazilian securities, including the common shares, on Brazilian stock exchanges without obtaining separate certificates of registration for each transaction. The registered foreign investors may also be entitled to favorable tax treatment. See "—E. Taxation—Brazilian Tax Considerations."

Pursuant to Resolution No. 4,373, an investor residing outside Brazil that is willing to invest pursuant to the mechanism described in the previous paragraph must: (i) appoint at least one financial institution or an institution authorized to operate by the Brazilian Central Bank as representative in Brazil that will be responsible for complying with the registration and reporting requirements and

[**Table of Contents**](#TOC)

reporting procedures of the Brazilian Central Bank and the CVM; (ii) register as a foreign investor with the CVM; (iii) appoint one or more custodians authorized by CVM; (iv) register the foreign investment with the Brazilian Central Bank; (v) appoint a tax representative in Brazil; and (vi) obtain a taxpayer identification number from the Brazilian federal tax authorities. The securities and other financial assets held by a foreign investor pursuant to Resolution No. 4,373 must be registered or maintained in deposit accounts or under the custody of an entity duly licensed by the Central Bank or by the CVM. In addition, the trading of securities is in general restricted to transactions carried out on the Brazilian stock exchanges or over-the-counter markets licensed by the CVM.

CVM Resolution No. 13/20, as amended, regulates in the Brazilian securities regulation the obligation of the representatives of investors residing outside Brazil to inform CVM of the movements and application of funds of the investors participating in collective accounts and holders of own accounts represented by them. Also, in the case of non-resident legal entity investors, Resolution No. 13/2020 provides the obligation to obtain registration with CVM prior to start operating as an investor in Brazil, provided that the information necessary to obtain this registration will be submitted to CVM by the representative of the non-resident investor and the registration will be granted automatically after the application for registration duly made by the representative.

**Registered Capital**

Amounts invested in common shares by a non-Brazilian holder who qualifies under Resolution No. 4,373 and obtains registration with the CVM<sup>1</sup>, or by the depositary representing an ADS holder, are eligible for registration with the Central Bank. Such registration (the amount so registered is referred to as registered capital) allows remittances of funds outside Brazil converted into foreign currency at the commercial market rate, acquired with the proceeds of distributions on, and amounts realized through, dispositions of such common shares. The registered capital per common share purchased in the form of ADS, or purchased in Brazil and deposited with the depositary in exchange for ADS, will be equal to its purchase price (stated in U.S. dollars). The registered capital per common share withdrawn upon cancellation of an ADS will be the U.S. dollar equivalent of (i) the average price of a common share on the Brazilian stock exchange on which the most common shares were traded on the day of withdrawal or (ii) if no common shares were traded on that day, the average price on the Brazilian stock exchange on which the most common shares were traded in the 15 trading sessions immediately preceding such withdrawal. The U.S. dollar equivalent will be determined on the basis of the average commercial market rates (buy/sell) quoted by the Central Bank on such date or dates.

An electronic registration has been issued in the name of the depositary with respect to the ADSs and is maintained by the custodian on behalf of the depositary. Pursuant to the registration, the custodian and the depositary are able to convert dividends and other distributions with respect to the common shares represented by ADSs into foreign currency and remit the proceeds outside Brazil. If a holder of ADSs exchanges such ADSs for common shares, such holder will be entitled to continue to rely on the depositary's registration for five business days after such exchange, following which such holder must seek to obtain its own electronic registration with the Central Bank, constituting a Brazilian financial institution as their representative for such purposes. Thereafter, any holder of common shares may not be able to convert into foreign currency and remit outside Brazil the proceeds from the disposition of, or distributions with respect to, such common shares, unless such holder is a duly qualified investor under Resolution No. 4,373 and obtains its own electronic registration.

If the holder does not qualify under Resolution No. 4,373 by registering with the CVM and the Central Bank and appoints a representative in Brazil to act directly in the Brazilian market to acquire common shares, the holder will be subject to a less favorable Brazilian tax treatment than a holder of ADSs. Regardless of registration under Resolution No. 4,373, residents of tax havens are subject to less favorable tax treatment than other foreign investors. See "—E. Taxation—Brazilian Tax Considerations."

Under current Brazilian legislation, CMN may delegate to the Central Bank the monopoly of all foreign exchange transactions, with the possibility of imposing temporary restrictions on remittances of foreign capital abroad in the event of a serious imbalance or an anticipated serious imbalance of Brazil's balance of payments. For approximately six months in 1989 and early 1990, the federal government froze all dividend and capital repatriations held by the Central Bank that were owed to foreign equity investors, to conserve Brazil's foreign currency reserves. These amounts were subsequently released in accordance with federal government directives. There can be no assurance that the federal government will not impose similar restrictions on foreign repatriations in the future.

<sup>1</sup>: Pursuant to CVM Resolution No. 13/20, natural persons investing individually are exempted from registering as foreign investors before CVM, and their representatives must submit the information electronically required by CVM on their behalf before commencing any sort of investment, therefore, in case the natural person ADS holder exchanges the ADS for common shares, they must constitute a representative who will include the information on their behalf before remitting the funds from the conversion abroad.

**E.** **Taxation**

The following discussion contains a description of the material Brazilian and U.S. federal income tax consequences arising from the acquisition, ownership and disposition of common shares or ADSs by certain holders or beneficial owners, as described below. This summary is based upon the tax laws and regulations of Brazil and the United States as of the date of this annual report, which are subject to change, possibly with retroactive effect, and to differing interpretations. You should consult your own tax advisers as to the Brazilian, U.S. federal or other tax consequences of the acquisition, ownership and disposition of common shares or ADSs, including, in particular, the effect of any state, local or non-U.S., non-Brazilian tax laws.

Although there is presently no income tax treaty entered into between Brazil and the United States, the tax authorities of the two countries have had discussions that may culminate in such a treaty. No assurance can be given, however, as to whether or when a treaty will enter into force or how it will affect the U.S. holders of common shares or ADSs. Brazil and the United States have, however, entered into a Tax Treaty Information Exchange Agreement, in order to establish an effective exchange of tax-related information between the two countries.

**Brazilian Tax Considerations**

The following discussion summarizes the main Brazilian tax consequences applicable to the purchase, ownership and disposal of common shares or ADSs by a holder that is not domiciled in Brazil for purposes of Brazilian taxation, or a Non-Resident Holder, but it does not purport to be a comprehensive description of all the tax considerations that may be relevant to these matters based upon the particular circumstances of a holder. Each Non-Resident Holder should consult his or her own tax adviser concerning the Brazilian tax consequences of an investment in common shares or ADSs. This summary is based upon federal tax laws of Brazil in effect as of the date hereof, which are subject to change and differing interpretations.

Although there is presently no income tax treaty between Brazil and the United States, the tax authorities of the two countries have had discussions that may culminate in such a treaty. No assurance can be given, however, as to whether or when a tax treaty will enter into force or how such a treaty would affect a U.S. holder of common shares or ADSs. The tax considerations described below do not take into account tax treaties entered into by Brazil and other countries.

***Taxation of Dividends***

Dividends paid by a Brazilian corporation, such as the Company, to an ADS Holder that is a Non-Resident Holder are currently not subject to withholding income tax, or WHT, in Brazil to the extent that such amounts are related to profits generated on or after January 1, 1996. Dividends paid from profits generated before January 1, 1996 may be subject to WHT at variable rates, according to the tax legislation applicable to each corresponding year.

Law No. 11,638/2007, or Law No. 11,638, significantly changed the Brazilian Corporate Law in order to align Brazilian generally accepted accounting principles with International Financial Reporting Standards, or IFRS. Nonetheless, Law No. 11,941/2009 introduced the Transitory Tax Regime, or RTT, in order to render neutral, from a tax perspective, all the changes provided by Law No. 11,638. Under the RTT, for tax purposes, legal entities should observe the accounting methods and criteria that were effective on December 31, 2007.

Profits determined pursuant to Law No. 11,638, or IFRS Profits, may differ from the profits calculated pursuant to the accounting methods and criteria as effective on December 31, 2007, or 2007 Profits.

While it was the general market practice to distribute exempted dividends with reference to the IFRS Profits, Rule No. 1,397, issued by the Brazilian tax authorities on September 16, 2013, established that legal entities should observe the 2007 Profits in order to determine the amount of profits that could be distributed as exempted income to their beneficiaries.

Any profits paid in excess of said 2007 Profits, or Excess Dividends, should, in the tax authorities' view and in the specific case of non-resident beneficiaries, be subject to the following rules of taxation: (1) 15.0% WHT, in case of beneficiaries domiciled abroad, but not in a Low or Nil Tax Jurisdiction, and (2) 25.0% WHT, in the case of beneficiaries domiciled in a Low or Nil Tax Jurisdiction.

In order to mitigate potential disputes on the subject, Law No. 12,973, dated May 13, 2014, or Law No. 12, 973, in addition to revoking the RTT, introduced a new set of tax rules (the "New Brazilian Tax Regime"), including new provisions with respect to

[**Table of Contents**](#TOC)

Excess Dividends. Under these new provisions: (1) Excess Dividends related to profits assessed from 2008 to 2013 are exempt; (2) potential disputes remain concerning the Excess Dividends related to 2014 profits, since Law No. 12,973 has not expressly excluded those amounts from taxation and Rule No. 1,492, issued by the Brazilian tax authorities on September 17, 2014, established they are subject to taxation when distributed by companies which have not elected to apply the New Brazilian Tax Regime in 2014; and (3) as of 2015, as the New Brazilian Tax Regime is mandatory and has completely replaced the RTT, dividends calculated based on IFRS Profits should be considered fully exempt.

Finally, there is currently legislation pending before the Brazilian Congress discussing the taxation of dividends. It is not possible to predict if the taxation of dividends will be effectively approved by the Brazilian Congress and how such taxation would be implemented.

***Distribution of Interest on Shareholders' Equity***

Law No. 9,249, dated December 26, 1995, as amended, allows a Brazilian corporation, such as the Company, to make payments to shareholders of interest on shareholders' equity as an alternative to carrying out dividend distributions and treat those payments as a deductible expense for the purposes of calculating Brazilian corporate income tax and social contribution on net income.

For tax purposes, this interest is limited to the daily variation of the pro rata variation of the TJLP, as determined by the Central Bank from time to time applied to certain equity accounts, and the amount of the distribution may not exceed the greater of:

● 50% of net income (after the deduction of the social contribution on net income and before taking into account the provision for corporate income tax and the amounts attributable to shareholders as interest on shareholders' equity) for the period in respect of which the payment is made; or

● 50% of the sum of retained profits and profits reserves for the year prior to the year in respect of which the payment is made.

Payments of interest on shareholders' equity to a Non-Resident Holder are subject to WHT at the rate of 15.0%, or 25.0% if the Non-Resident Holder is domiciled in a Low or Nil Tax Jurisdiction.

These payments may be included, at their net value, as part of any mandatory dividend. To the extent that such payments are accounted for as part of the mandatory dividend, under current Brazilian law, we are obliged to distribute to shareholders an additional amount sufficient to ensure that the net amount received by the shareholders, after payment by us of applicable WHT, plus the amount of declared dividends, is at least equal to the mandatory dividend. The distribution of interest on shareholders' equity must be proposed by our board of directors and is subject to subsequent ratification by the shareholders at the shareholders' meeting.

***Capital Gains***

*Sale of ADSs*

According to Law No. 10,833, capital gains earned on the disposal of assets located in Brazil by a Non-Resident Holder, whether to another non-Brazilian resident or to a Brazilian resident are subject to taxation in Brazil.

Our understanding is that ADSs do not qualify as assets located in Brazil for the purposes of Law No. 10,833 because they represent securities issued and renegotiated in an offshore exchange market and, therefore, should not be subject to the Brazilian WHT. However, considering the lack of any judicial court ruling in respect thereto, we cannot assure you of how tax authorities and Brazilian courts would interpret the definition of assets located in Brazil in connection with the taxation of gains realized by a Non-Resident Holder on the disposal of ADSs to another non-Brazilian resident. If the ADSs are deemed to be assets located in Brazil, gains recognized by a Non-Resident Holder from the sale or other disposition to either a non-resident or a resident in Brazil may be subject to income tax in Brazil as further described below.

*Conversion of ADSs into Common Shares*

Although there is no clear regulatory guidance, the exchange of ADSs for common shares should not be subject to Brazilian tax. Non-Resident Holders may exchange ADSs for the underlying common shares, sell the common shares on a Brazilian stock exchange and remit abroad the proceeds of the sale, according to the regulations of the Central Bank.

[**Table of Contents**](#TOC)

Upon receipt of the underlying common shares in exchange for ADSs, Non-Resident Holders may also elect to register with the Central Bank the U.S. dollar value of such common shares as a foreign portfolio investment under Resolution No. 4,373, which will entitle them to the tax treatment described above.

Alternatively, a Non-Resident Holder is also entitled to register with the Central Bank the U.S. dollar value of such common shares as a foreign direct investment under Law No. 4,131/62, in which case the respective sale would be subject to the tax treatment applicable to transactions carried out of by a Non-Resident Holder that is not registered before the Central Bank and the CVM in accordance with Resolution No. 4,373.

*Sale of Common Shares*

Capital gains assessed on a Non-Resident Holder on the disposition of common shares carried out on a Brazilian stock exchange (which may include transactions carried out on the organized over-the-counter market, or OTC) are:

● exempt from income tax when realized by a Non-Resident Holder that (1) has registered its investment in Brazil with the Central Bank under the rules of CMN Resolution No. 4,373, or a 4,373 Holder, and (2) is not resident or domiciled in a Low or Nil Tax Jurisdiction;

● subject to income tax at a rate of 15.0% in the case of gains realized by (1) a Non-Resident Holder that (A) is not a 4,373 Holder and (B) is not resident or domiciled in a Low or Nil Tax Jurisdiction; or (2) a Non-Resident Holder that (A) is a 4,373 Holder, and (B) is resident or domiciled in a Low or Nil Tax Jurisdiction. In this case, a withholding income tax of 0.005% of the sale value shall be applicable and withheld by the intermediary institution (i.e., a broker) that receives the order directly from the Non-Resident Holder, which can be later offset against any income tax due on the capital gain earned by the Non-Resident Holder; or

● subject to income tax at a rate of up to 25.0% in the case of gains realized by a Non-Resident Holder that (1) is not a 4,373 holder, and (2) is resident or domiciled in a Low or Nil Tax Jurisdiction. In this case, a withholding income tax of 0.005% of the sale value shall be applicable and withheld by the intermediary institution (i.e., a broker) that receives the order directly from the Non-Resident Holder, which can be later offset against any income tax due on the capital gain earned by the Non-Resident Holder.

Any other gains assessed on a sale or disposition of common shares that is not carried out on a Brazilian stock exchange are subject to (1) income tax at a rate ranging from 15.0% up to 22.5% when realized by a Non-Resident Holder that is not resident or domiciled in a Low Tax Jurisdiction; and (2) income tax at a rate of 25.0% when realized by a Non-Resident Holder that is domiciled or resident in a Low Tax Jurisdiction. If these gains are related to transactions conducted on the Brazilian non-organized over-the-counter market with intermediation, a WHT of 0.005% on the sale value will also apply and can be used to offset the income tax due on the capital gain.

Any exercise of preemptive rights relating to common shares or ADSs will not be subject to Brazilian withholding income tax. Any gain on the sale or assignment of preemptive rights relating to common shares by the depositary on behalf of holders of ADSs will be subject to Brazilian income taxation according to the same rules applicable to the sale or disposal of common shares.

In the case of a redemption of common shares or a capital reduction by a Brazilian corporation, such as the Company, the positive difference between the amount received by a Non-Resident Holder and the acquisition cost of the common shares redeemed, including these underlying ADSs, is treated as a capital gain derived from the sale or exchange of shares not carried out on a Brazilian stock exchange market, and is therefore subject to income tax at the progressive rate from 15% to 22.5%, and 25% for residents in a Low or Nil Taxation Jurisdiction.

As a general rule, the gains realized as a result of the disposal of common shares, including these underlying ADSs, is the positive difference between the amount realized on the sale or exchange of the common shares and their acquisition cost.

There is no assurance that the current preferential treatment for a Non-Resident Holder of ADSs and a 4,373 Holder of common shares will continue or that it will not change in the future.

[**Table of Contents**](#TOC)

*Gains on the exchange of common shares for ADSs*

The deposit of common shares in exchange for ADSs may be subject to Brazilian income tax on capital gains if the amount previously registered with the Central Bank as a foreign investment in common shares or, in the case of other market investors under Resolution No. 4,373, the acquisition cost of the common shares, as the case may be, is lower than:

● the average price per common share on the Brazilian stock exchange on which the greatest number of such common shares were sold on the day of deposit; or

● if no common shares were sold on that day, the average price on the Brazilian stock exchange on which the greatest number of common shares were sold during the 15 preceding trading sessions.

The difference between the amount previously registered, or the acquisition cost, as the case may be, and the average price of the common shares, calculated as set forth above, is considered a capital gain.

***Discussion on Low or Nil Taxation Jurisdictions***

On June 4, 2010, the Brazilian tax authorities enacted Normative Ruling No. 1,037 listing (1) the countries and jurisdictions considered as Low or Nil Taxation Jurisdictions or where the local legislation does not allow access to information related to the shareholding composition of legal entities, to their ownership or to the identity of the effective beneficiary of the income attributed to non-residents, and (2) the privileged tax regimes, which definition is provided by Law No. 11,727, of June 23, 2008, or Law No. 11,727.

A Low or Nil Taxation Jurisdiction is a country or location that (1) does not impose taxation on income, (2) imposes income tax at a maximum rate lower than 20.0%, or (3) imposes restrictions on the disclosure of shareholding composition or the ownership of the investment. A regulation issued by the Brazilian tax authorities on November 28, 2014 (Ordinance No. 488, of 2014) decreased, from 20.0% to 17.0%, the minimum threshold for certain specific cases. The reduced 17.0% threshold applies only to countries and regimes aligned with international standards of fiscal transparency in accordance with rules to be established by the Brazilian tax authorities. Although Ordinance No. 488 has lowered the threshold rate, Normative Ruling No. 1,037, which identifies the countries considered to be Low or Nil Tax Jurisdictions and the locations considered as privileged tax regimes, has not been amended yet to reflect such threshold modification.

Law No. 11,727 created the concept of "privileged tax regimes," which encompasses the countries and jurisdictions that (1) do not tax income or tax it at a maximum rate lower than 20.0%; (2) grant tax advantages to a non-resident entity or individual (a) without the need to carry out a substantial economic activity in the country or jurisdiction, or (b) conditioned to the non-exercise of a substantial economic activity in the country or jurisdiction; (3) do not tax or tax proceeds generated abroad at a maximum rate lower than 20.0%; or (4) restrict the ownership disclosure of assets and ownership right or restrict disclosure about economic transactions carried out. Although we believe that the best interpretation of the current tax legislation is that the above mentioned "privileged tax regime" concept should apply solely for purposes of Brazilian transfer pricing and thin capitalization rules, among other rules that make express reference to the concepts, we can provide no assurance that tax authorities will not interpret the rules as applicable also to a Non-Resident Holder on payments of interest on shareholders' equity.

Currently, the understanding of the Brazilian tax authorities is that the rate of 15.0% of WHT applies to payments made to beneficiaries resident in privileged tax regimes (Answer to Advance Tax Ruling Request COSIT No. 575, of December 20, 2017). In any case, if Brazilian tax authorities determine that payments made to a Non-Resident Holder under a privileged tax regime are subject to the same rules applicable to payments made to Non-Resident Holders located in a Low or Nil Tax Jurisdictions, the withholding income tax applicable to such payments could be assessed at a rate up to 25.0%.

We recommend investors to consult their own tax advisors from time to time to verify any possible tax consequence arising from Normative Ruling No. 1,037 and Law No. 11,727. If the Brazilian tax authorities determine that payments made to a Non-Resident Holder are considered to be made under a "privileged tax regime," the WHT applicable to such payments could be assessed at a rate of up to 25.0%.

[**Table of Contents**](#TOC)

***Other Brazilian Taxes***

There are no Brazilian federal inheritance, gift or succession taxes applicable to the ownership, transfer or disposal of common shares or ADSs by a Non-Resident Holder. Gift and inheritance taxes, however, may be levied by some states on gifts made to or inheritances bestowed by the Non-Resident Holder on individuals or entities resident or domiciled within such states in Brazil. There is no Brazilian stamp, issue, registration or similar taxes or duties payable by a Non-Resident Holder of common shares or ADSs.

***Taxation of Foreign Exchange Transactions (IOF/Exchange)***

Pursuant to Decree No. 6,306/07, the conversion into foreign currency or the conversion into Brazilian currency of the proceeds received or remitted by a Brazilian entity from a foreign investment in the Brazilian securities market, including those in connection with the investment by a Non-Resident Holder in the common shares and ADSs, may be subject to the Tax on Foreign Exchange Transactions, or IOF/Exchange. Currently, the applicable rate for almost all foreign currency exchange transactions is 0.38%. Currently, foreign currency exchange transactions carried out for the inflow of funds in Brazil for investment in the Brazilian financial and capital market made by a foreign investor (including a Non-Resident Holder, as applicable) are subject to IOF/Exchange at a 0% rate. The IOF/Exchange rate will also be 0% for the outflow of resources from Brazil related to these types of investments, including payments of dividends and interest on shareholders' equity and the repatriation of funds invested in the Brazilian market. Furthermore, the IOF/Exchange is currently levied at a 0% rate for the conversion of ADSs into common shares held by foreign investors under the 4,373 Holders regime. In any case, the Brazilian government is permitted to increase the rate to a maximum of 25% at any time, with respect to future transactions. Any increase in the rate would not apply retroactively.

***Tax on Bonds and Securities Transactions (IOF/Bonds)***

Pursuant to Decree 6,306/07, the Tax on Bonds and Securities Transactions, or IOF/Bonds, may be imposed on any transaction involving bonds and securities even if the transactions are performed on a Brazilian stock exchange. The rate of this tax for transactions involving common shares is currently 0%, but the Brazilian government may increase such rate up to 1.5% per day, with respect to future transactions. Currently, the issuance of depositary receipts traded outside of Brazil which underlying shares are issued by a Brazilian company and listed on a Brazilian stock exchange are also subject to IOF/Bonds at the 0% rate. Any increase in the rate would not apply retroactively.

**U.S. Federal Income Tax Considerations**

The following are the material U.S. federal income tax consequences to U.S. Holders (as defined below) of owning and disposing of common shares or ADSs, but this is not a comprehensive description of all of the tax considerations that may be relevant to a particular person's decision to hold such securities. The discussion applies only to U.S. Holders that hold common shares or ADSs as capital assets for U.S. federal income tax purposes, and it does not describe all of the tax consequences that may be relevant in light of a U.S. Holder's particular circumstances, including alternative minimum tax consequences, the potential application of the provisions of the Internal Revenue Code of 1986, or the Code, known as the Medicare contribution tax, the effects of any state, local or non-U.S. tax laws and tax consequences applicable to U.S. Holders subject to special rules, such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· certain financial institutions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· dealers or traders in securities who use a mark-to-market method of tax accounting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· persons holding common shares or ADSs as part of a hedge, "straddle," integrated transaction or similar transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· entities classified as partnerships or other pass-through entities for U.S. federal income tax purposes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· tax-exempt organizations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· regulated investment companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· real estate investment trusts;

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· insurance companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· persons that own or are deemed to own 10% or more of our stock by vote or value;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· persons required for U.S. federal income tax purposes to conform the timing of income accruals to their financial statements under Section 451 of the Code;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· persons who acquired our common shares or ADSs pursuant to the exercise of any employee stock option or otherwise as compensation; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· persons holding common shares or ADSs in connection with a trade or business conducted outside of the United States.

If an entity that is classified as a partnership for U.S. federal income tax purposes holds common shares or ADSs, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships holding common shares or ADSs and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of holding and disposing of the common shares or ADSs.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed U.S. Treasury regulations, all as of the date hereof. These laws are subject to change, possibly on a retroactive basis. This discussion is also based in part on representations by the depositary and assumes that each obligation under the Deposit Agreement and any related agreement will be performed in accordance with its terms.

You are a "U.S. Holder" if, for U.S. federal income tax purposes, you are a beneficial owner of common shares or ADSs and you are:

● an individual citizen or resident of the United States;

● a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or the District of Columbia; or

● an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

THE SUMMARY OF U.S. FEDERAL INCOME TAX CONSEQUENCES SET OUT BELOW IS INTENDED FOR GENERAL INFORMATION PURPOSES ONLY. U.S. HOLDERS OF COMMON SHARES OR ADSs ARE URGED TO CONSULT WITH THEIR OWN TAX ADVISERS WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF OWNING OR DISPOSING OF COMMON SHARES OR ADSs, INCLUDING THE APPLICABILITY AND EFFECT OF STATE, LOCAL, NON-U.S. AND OTHER TAX LAWS AND POSSIBLE CHANGES IN TAX LAWS.

In general, if you own ADSs, you will be treated as the owner of the underlying shares represented by those ADSs for U.S. federal income tax purposes. Accordingly, no gain or loss will be recognized if you exchange ADSs for the underlying shares represented by those ADSs.

This discussion assumes that we are not, and will not become, a passive foreign investment company, as described below.

**Taxation of Distributions**

Distributions paid on common shares or ADSs (including distributions to shareholders that are treated as interest on shareholders' equity for Brazilian tax purposes) will generally be treated as dividends to the extent paid out of current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, it is expected that distributions generally will be reported to U.S. Holders as dividends. Subject to applicable limitations that may vary depending upon your circumstances, dividends paid by "qualified foreign corporations" to certain non-corporate U.S. Holders are taxable at the rates applicable to long-term capital gains. A foreign corporation is treated as a "qualified foreign corporation" with respect to dividends paid on stock that is readily tradable on a securities market in the United States, such as the NYSE, where our ADSs are traded. You should consult your tax adviser regarding the availability of the reduced tax rate on dividends in your particular circumstances.

[**Table of Contents**](#TOC)

The amount of a dividend will include any amounts withheld in respect of Brazilian taxes. The amount of the dividend will be treated as foreign-source dividend income to you and will not be eligible for the dividends-received deduction generally allowed to U.S. corporations under the Code. Dividends will be included in your income on the date of your, or in the case of ADSs, the depositary's, receipt of the dividend. The amount of any dividend income paid in *reais* will be a U.S. dollar amount calculated by reference to the exchange rate in effect on the date of such receipt, regardless of whether the payment is in fact converted into U.S. dollars. If the dividend is converted into U.S. dollars on the date of receipt, you should not be required to recognize foreign currency gain or loss in respect of the dividend income. If the dividend is not converted into U.S. dollars on the date of receipt, you will have a basis in *reais* equal to the U.S. dollar value on the date of receipt. You may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt.

Subject to applicable limitations that may vary depending upon your circumstances, Brazilian income taxes withheld from dividends on common shares or ADSs might be creditable against your U.S. federal income tax liability. The rules governing foreign tax credits are complex, and, therefore, you should consult your tax adviser regarding the availability of foreign tax credits in your particular circumstances. In particular, you may use foreign tax credits to offset only the portion of your U.S. tax liability that is attributable to foreign-source income. This limitation on foreign taxes eligible for credit is calculated separately with regard to specific classes of income. In addition, you must satisfy minimum holding period requirements in order to be eligible to claim a foreign tax credit for foreign taxes withheld on dividends. Recently issued Treasury regulations, which apply to foreign taxes paid or accrued in taxable years beginning on or after December 28, 2021 (the "Final Treasury Regulations"), impose significant additional requirements on the foreign taxes (including withholding taxes) for which a foreign tax credit can be claimed. We have not determined whether these requirements have been met with respect to any withholding tax imposed on dividends on common shares or ADSs and, therefore, you should consult your tax advisers regarding the availability of foreign tax credits for any amounts withheld with respect to dividends on common shares or ADSs to which the Final Treasury Regulations apply.

Instead of claiming a credit, you may, at your election, deduct such Brazilian taxes in computing your taxable income, subject to generally applicable limitations under U.S. law. An election to deduct foreign taxes instead of claiming foreign tax credits applies to all taxes paid or accrued in the taxable year to foreign countries and possessions of the United States.

**Sale or Other Disposition of Common Shares or ADSs**

For U.S. federal income tax purposes, gain or loss you realize on the sale or other disposition of common shares or ADSs will generally be capital gain or loss, and will generally be long-term capital gain or loss if you held the common shares or ADSs for more than one year. The amount of your gain or loss will equal the difference between your tax basis in the common shares or ADSs disposed of and the amount realized on the disposition, in each case, as determined in U.S. dollars. If a Brazilian tax on gains is withheld on the sale or disposition of common shares or ADSs, a U.S. Holder's amount realized will include the gross amount of the proceeds of such sale or disposition before deduction of the Brazilian tax. See "—Brazilian Tax Considerations—Capital Gains" for a description of when a disposition may be subject to taxation by Brazil. Such gain or loss will generally be U.S.-source gain or loss for foreign tax credit purposes. The limitations of the Final Treasury Regulations may preclude you from claiming a credit for all or a portion of any Brazilian taxes imposed on any such gains. In addition, for any foreign taxes paid or accrued in taxable year beginning on or after December 28, 2021, the Final Treasury Regulations generally will preclude you from claiming a foreign tax credit with respect to any tax imposed on gains from the disposition of shares by a jurisdiction, such as Brazil, that does not have an applicable income tax treaty with the United States, although such taxes may be applied to reduce the amount realized by you on the disposition. Consequently, you are not currently expected to be able to claim a foreign tax credit for any Brazilian tax imposed on any gains from the sale or other disposition of common shares or ADSs. However, you may, at your election, deduct such Brazilian income taxes in computing taxable income, subject to generally applicable limitations under U.S. law. An election to deduct foreign taxes instead of claiming foreign tax credits applies to all foreign taxes paid or accrued in the taxable year. You should consult your tax adviser as to whether the Brazilian tax on gains may be creditable against your U.S. federal income tax on foreign-source income from other sources.

**Other Brazilian Taxes**

You should note that any Brazilian IOF/Exchange tax (as discussed above under "—Brazilian Tax Considerations") will not be a creditable foreign tax for U.S. federal income tax purposes, although you may be entitled to deduct such tax, subject to applicable limitations under U.S. law. You should consult your tax adviser regarding the U.S. federal income tax consequences of the payment of Brazilian IOF/Exchange tax, including whether you may claim a deduction for such tax or should instead include the amount of tax paid in your initial basis in the common shares or ADSs.

**Passive Foreign Investment Company Rules**

We believe that we were not a "passive foreign investment company," or a PFIC, for U.S. federal income tax purposes for our 2022 taxable year. However, because PFIC status depends on the composition of a company's income and assets and the market value of its assets from time to time, there can be no assurance that we will not be a PFIC for any taxable year. If we were a PFIC for any taxable year during which a U.S. Holder held common shares or ADSs, gain recognized by such U.S. Holder on a sale or other disposition (including certain pledges) of the common shares or ADSs would be allocated ratably over the U.S. Holder's holding period for the common shares or ADSs. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for such taxable year, and an interest charge would be imposed on the resulting tax liability. Further, to the extent that any distribution received by a U.S. Holder on its common shares or ADSs exceeded 125% of the average of the annual distributions on common shares or ADSs received by the U.S. Holder during the preceding three years or the U.S. Holder's holding period, whichever is shorter, that distribution would be subject to taxation in the same manner. Certain elections may be available that would result in alternative treatments (such as mark-to-market treatment) of the common shares or ADSs. U.S. Holders should consult their tax advisers to determine whether any of these elections would be available and, if so, what the consequences of the alternative treatments would be in their particular circumstances. If we are a PFIC for any taxable year during which a U.S. Holder owns our common shares or ADSs, the U.S. Holder will generally be required to file Internal Revenue Service ("IRS") Form 8621 with its annual U.S. federal income tax return, subject to certain exceptions.

***Information Reporting and Backup Withholding***

Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting and may be subject to backup withholding, unless (i) you are a U.S. corporation or other exempt recipient or (ii) in the case of backup withholding, you provide a correct taxpayer identification number and certify that you are not subject to backup withholding. The amount of any backup withholding from a payment to you will be allowed as a credit against your U.S. federal income tax liability and may entitle you to a refund, provided that the required information is timely furnished to the IRS.

Certain U.S. Holders who are individuals or closely-held entities may be required to report information on IRS Form 8938 relating to their ownership of securities of a non-U.S. person, subject to certain exceptions (including an exception for securities held in certain accounts maintained by financial institutions, in which case the accounts may be reportable if maintained by a non-U.S. financial institution). U.S. Holders are urged to consult their tax advisers regarding the effect, if any, of these rules on their ownership and disposition of common shares or ADSs.

U.S. HOLDERS OF OUR COMMON SHARES OR ADSs SHOULD CONSULT THEIR OWN TAX ADVISERS AS TO THE BRAZILIAN, U.S. FEDERAL, STATE, LOCAL AND OTHER TAX CONSEQUENCES OF THE OWNERSHIP AND DISPOSITION OF OUR COMMON SHARES OR ADSs BASED UPON THEIR PARTICULAR CIRCUMSTANCES.

#### Item 11. Quantitative and Qualitative Disclosures About Market Risk
We are exposed to various market risks as a result of our trading operations, debts obtained to finance our financial derivative activities and instruments, including exchange rate risk, interest rate risk, debt acceleration risk and credit risk. To help us manage our risks, we conduct an assessment of our financial assets and liabilities against market values based on available information and appropriate valuation methodologies. However, the interpretation of market information, as well as the selection of methodologies, requires considerable judgment and reasonable estimates to produce adequate values of achievement. As a result, our valuation estimates do not necessarily indicate the values, which will be realized in the current market. The use of different market approaches and/or methodologies for estimates can have a significant effect on the estimated values of achievement.

We also enter into derivative instruments to manage the risks to which we are exposed in accordance with our risk management policy. We do not have derivative instruments for speculative purposes.

To further assist our risk management, we perform fair value analyses of our derivative financial instruments, as well as sensitivity analyses of our risk variables and our risk of net exposure. For more details on the results of our valuation analysis, risk management strategies and sensitivity analysis of our derivative financial instruments, see note 33 in our consolidated financial statements.

In addition, the volatile market conditions arising from the COVID-19 pandemic may result in significant changes in exchange rates, interest rates and stock prices, both ours and those of third parties that we use to value certain of our long-term investments. See Part II Item IA. "Risk Factors" in this document for further discussion on the impact of the COVID-19 pandemic on our business, operating results and financial conditions.

On November 23, 2020, we entered into a deposit agreement with Citibank N.A., pursuant to which Citibank N.A. became our depositary.

Citibank N.A. has agreed to reimburse us for expenses related to the establishment and maintenance expenses of the ADS program. The depositary has agreed to reimburse us for our continuing annual stock exchange listing fees. The depositary has also agreed to pay the standard out-of-pocket maintenance costs for the ADRs, which consist of the expenses of postage and envelopes for mailing annual and interim financial reports, printing and distributing dividend checks, electronic filing of U.S. Federal tax information, mailing required tax forms, stationery, postage, facsimile, and telephone calls. It has also agreed to reimburse us annually for certain investor relations programs or special investor relations promotional activities. In certain instances, the depositary has agreed to provide additional payments to us based on any applicable performance indicators relating to the ADR facility. There are limits on the amount of expenses for which the depositary will reimburse us, but the amount of reimbursement available to us is not necessarily tied to the amount of fees the depositary collects from investors. During 2022, we received from Citibank N.A., our depositary, US$3.0 million, for the services described above.

**PART II**

#### Item 13. Defaults, Dividend Arrearages and Delinquencies
As of December 31, 2022, we were not in default under any of our obligations and there were no dividend arrearages or delinquencies.

#### Item 14. Material Modifications to the Rights of Security Holders and Use of Proceeds
On October 1, 2020, the Extraordinary General Meeting of the Company approved, and the Special General Meeting of the Company's Preferred Shareholders ratified, the Conversion of all the preferred shares issued by the Company into common shares, in the proportion of one (1) common share for each one (1) preferred share and its implementation by the Company's officers as well as the relevant changes to our Bylaws to reflect the Conversion.

After the concession and the expiration of the term for shareholders to exercise withdrawal rights, we proceeded with the Conversion, and the last trading session for our preferred shares on the B3 and for our ADSs backed by preferred shares on the NYSE was on November 20, 2020. Therefore, as of November 23, 2020, "VIVT3" represents the only ticker symbol for trading of the Company's common shares on the B3, and ADSs backed by our common shares began trading on the NYSE under the ticker symbol "VIV," with each ADS representing one common share. Each of our common shares entitles its holder to one vote at our annual and extraordinary shareholders' meetings, whereas prior to the Conversion, holders of our preferred shares were generally not entitled to vote, except under limited circumstances.

For a description of the rights of holders of our common shares and ADSs represented by common shares, see "Item 10. Additional Information—B. Memorandum and Articles of Association—Description of our Bylaws" and Exhibit 2.2 to this annual report.

#### Item 15. Controls and Procedures
***Management´s Evaluation over Disclosure Controls and Procedures***

Our Chief Executive Officer and our Chief Financial Officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this Form 20-F, have concluded that, as of such date, our disclosure controls and procedures were effective.

There are, as described below, inherent limitations to the effectiveness of any internal control system, including disclosure controls and procedures. Accordingly, even effective disclosure controls and procedures can provide only reasonable assurance of achieving their control objectives.

***Management's Annual Report on Internal Control over Financial Reporting***

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Exchange Act. Our internal control over financial reporting is designed to provide reasonable assurance as to the reliability of financial reporting and the preparation of consolidated financial statements for external purposes, in accordance with generally accepted accounting principles. Generally accepted accounting principles refer to International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB).

Our internal control over financial reporting includes those policies and procedures that:

● Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

● Provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of Telefônica Brasil are being made only in accordance with authorizations of management and directors; and

[**Table of Contents**](#TOC)

● Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of Telefônica Brasil's assets that could have a material effect on the consolidated financial statements.

Any internal control system, no matter how well designed, has inherent limitations, including the possibility of human error and the circumvention or overriding of controls and procedures, which may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness for future periods are subject to the risk that controls may become inadequate because of changes in conditions or because the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of internal control over financial reporting as of December 31, 2022. In making this assessment, it used the criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Telefônica Brasil's management has excluded from the scope of its assessments of the internal control over financial reporting the operations and related assets of Garliava RJ Infraestrutura e Redes de Telecomunicações S.A. (hereinafter "Garliava"), which Telefônica Brasil integrated from April 20, 2022. Total assets, total revenues and net income subject to Garliava's internal control over financial reporting represented 1.4%, 2.3% and 0.1%, respectively, for the year ended December 31, 2022. Based on the assessment performed and those criteria, Telefônica Brasil concluded that as of December 31, 2022, Telefônica Brasil's internal control over financial reporting was effective.

***Report of the Registered Public Accounting Firm***

PricewaterhouseCoopers Brasil Ltda., an independent registered public accounting firm (PCAOB ID 1351), has issued a report both on the consolidated financial statements as of and for the year ended December 31, 2022 and on the effectiveness of Telefónica's internal control over financial reporting under auditing standards of the Public Company Accounting Oversight Board (United States). The report is included on page F-2.

***Changes in Internal Control over Financial Reporting***

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15(d) or 15d-15(d) under the Exchange Act that occurred during the period covered by this Annual Report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**Item 16.** **[Reserved]**

#### Item 16a. Audit Committee Financial Expert
Our Control and Audit Committee is comprised of a minimum of three (3) and a maximum of five (5) nonexecutive directors. See "Item 6. Directors, Senior Management and Employees—C. Board Practices—Committees—Control and Audit Committee." Our Board of Directors has designated José María Del Rey Osorio, an independent member of our Board of Directors in accordance with the rules of the B3's Novo Mercado and a member of our Control and Audit Committee, as the Company's "audit committee financial expert," as such term is defined by the SEC. There are some similar functions between the Control and Audit Committee and our Fiscal Board (*Conselho Fiscal*), the latter of which meets the requirements of the general exemption from the listing standards for audit committees set forth in Exchange Act Rule 10A-3(c)(3). See "Item 16d. Exemptions from the Listing Standards for Audit Committees Procedures."

#### Item 16b. Code of Ethics
Our administrations and employees ethics conduct, daily performed, are governed by a code of business conduct and ethics called the "*Princípios de Negócio Responsável*" or the Telefónica Responsible Business Principles, which is reviewed periodically and approved by the board. Its global guidelines define the way we do business with all stakeholders and generate long term value. In addition, the Telefónica Responsible Business Principles set forth mechanisms for decision making when facing ethical dilemmas and situations that eventually can be considered not in accordance with the law. We promote periodical training to our employees aiming to reinforce our code of ethics concepts and principles reaching 94.8% of our personnel.

The Compliance Department's mission is to be a role model in ensuring the applicability of anti-corruption compliance law and corporate ethics, generating value to stakeholders, protecting the company and its employees, reducing risks of non-compliance and

[**Table of Contents**](#TOC)

bolstering our culture, which is based on ethics and integrity. The Compliance Department works together with other areas of the company to maintain our business best practices and provides updates on our compliance program to the Audit Committee.

At Telefônica Brasil, the compliance program, named as #VivoDeAcordo, has important pillars to its solid implementation: total commitment from top management; a robust structure of highly qualified and skilled employees responsible for the program's actions; regular analysis and evaluation of business risks; internal policies addressing diverse subjects, such as prevention of corruption, conflict of interests, gifts and entertainment, information security, among others, in line with global guidelines and internal regulations well-structured and available to all employees; periodic compliance training for current and new employees and an active channel to answer questions about the entire program.

The program applies to all employees (including directors and executive officers) and also to allies. To enhance integrity culture, initiatives of prevention, detection, remediation and integrity are constantly released, such as: regular communication on ethics topics; anticorruption training; promotion of compliance channel "Fale com #VivoDeAcordo" and our policies, which are available in our intranet policy portal.

To reinforce our commitment to maintaining a Compliance Program of excellence, in 2020, 2021 and 2022, we obtained the DSC 10.000 certificate (Guidelines for the Compliance System).

The company is aware of the importance of its supply chain for its international presence, the impact and involved values in its business transactions volume. For this reason, our company promotes, establishes and maintains high level of responsible behavior with respect of its suppliers, promoting among them not only compliance quality/service standards, but also ethical, social, environmental and privacy standards in any relationship with our supply chain.

Stimulating sustainability throughout the supply chain is an important challenge for the telecommunications sector. At the Company, this business relationship, guided by ethics and transparency, is based on the guidelines of the Sustainability Policy for the Supply Chain, implemented since 2016 and revised in 2019. The document establishes the Principles and Minimum Criteria for Responsible Business that suppliers must follow.

As one of the pillars of our code of ethics (*Princípios de Negócio Responsável*), the respect and commitment to human rights guide the regular and periodic evaluation of the impacts in our value chain. Since 2010, we have been signatories to the Global Compact, a UN initiative to encourage companies to follow corporate social responsibility and sustainability policies through the adoption of ten principles related to human rights, labor, environment and corruption.

Corporate social responsibility has always been present in our agenda, and, in 2020, we adopted the ISO 26000 (Guidance on Social Responsibility) management model. Through the ISO 26000 guidelines, we improve our organizational culture, minimizing the risks of our business, and ensuring an increasingly sustainable performance through ethical and transparent behavior.

The Telefónica Responsible Business Principles are available and open to consultation for employees on the Telefónica Intranet site as well as for the general public on the Telefónica external website (https://www.telefonica.com/en/sustainability-innovation/how-we-work/business-principles/). These Responsible Business Principles were modified in 2022 in order to include and/or update our commitments, addressing topics such as: ethical and responsible management, corporate governance and internal control, respect and promotion of human rights and digital rights, commitment to the environment, innovation, development and responsible use of technology, responsible communication as well as reinforcing the company's commitment to zero tolerance for corruption. No waivers were granted in 2022.

#### Item 16c. Principal Accountant Fees and Services
In the chart below we have detailed the expenses accrued in respect of the fees for services rendered by PricewaterhouseCoopers Auditores Independentes, our independent auditor for the fiscal years ended December 31, 2022, 2021 and 2020:

| Audit-Related Fees | 0.2 | 0.3 | 0.3 |
| **Total** | **16.8** | **13.2** | **12.6** |

---

**Audit Fees**

Services included under this heading are mainly the audit of the annual and reviews of interim financial statements, work to comply with the requirements of the Sarbanes-Oxley Act (Section 404) and the review of the 20-F report to be filed with US Securities and Exchange Commission (SEC).

**Audit-Related Fees**

This heading mainly includes services related to the review of the information required by regulatory authorities and the review of corporate responsibility reports.

#### Item 16d. Exemptions From the Listing Standards for Audit Committees Procedures
Brazilian Corporate Law requires that we have a statutory Fiscal Board (Conselho Fiscal) composed of three (3) to five (5) members and alternates who are elected by the general shareholders' meeting. The statutory Fiscal Board operates independently from management and from a company's external auditors, and the members of our statutory Fiscal Board are all financially literate. Its main function is to monitor the activities of management, examine the financial statements of each fiscal year and provide a formal report to our shareholders. We are relying on the general exemption from the listing standards relating to audit committees contained in Rule 10A-3(c)(3) under the Exchange Act because our statutory Fiscal Board meets the requirements of the general exemption set forth in Exchange Act Rule 10A-3(c)(3). See "Item 6. Directors, Senior Management and Employees—C. Board Practices—Fiscal Board." Our statutory Fiscal Board is primarily charged with certain advisory, oversight and review functions with respect to the company's financial statements; however, the statutory Fiscal Board, as required by Brazilian Corporate Law, has only an advisory role and does not participate in the management of the company. Indeed, decisions of the statutory Fiscal Board are not binding on the company under Brazilian Corporate Law. Our Board of Directors, under Brazilian Corporate Law, is the only entity with the legal capacity to appoint and retain any independent registered public accounting firm and decide the budget appropriation with respect to such auditors.

Since Brazilian Corporate Law does not specifically grant our statutory Fiscal Board the power to establish receipt, retention and complaint procedures regarding accounting, internal control and audit matters, or create policies for the confidential, anonymous treatment of employee concerns regarding accounting or auditing matters, we have established a Control and Audit Committee as a best corporate governance practice to address these various issues. See "Item 6. Directors, Senior Management and Employees—C. Board Practices—Committees—Control and Audit Committee."

The Fiscal Board is not the equivalent of, or wholly comparable to, a U.S. audit committee. Among other differences, it is not required to meet the standards of "independence" established in Rule 10A-3 and is not fully empowered to act on matters that are required by Rule 10A-3 to be within the scope of an audit committee's authority. Nonetheless, we believe that our use of a fiscal board in accordance with Brazilian Corporate Law in combination with our Control and Audit Committee, as opposed to the provisions set forth in Exchange Act Rule 10A-3(b), does not materially adversely affect the ability of the Fiscal Board to act independently, satisfy the other applicable requirements of Exchange Act Rule 10A-3 (to the extent permitted by Brazilian Corporate Law) or to fulfill its fiduciary and other obligations under Brazilian law.

#### Item 16e. Purchases of Equity Securities by the Issuer and Affiliated Purchasers
***Plan for the Purchase of Shares Issued by the Company.***

Our board of directors approved on February 22, 2022, pursuant to article 15, item XV of our bylaws and the CVM Instruction No. 567/2015, or Instruction No. 567, a Share Buyback Program for the acquisition of shares issued by the Company, or the Program, for subsequent cancellation, sale or holding in treasury, as follows:

#### Item 16f. Change in Registrant's Certifying Accountant
Not applicable.

#### Item 16g. Corporate Governance
***Principal Differences Between U.S. and Brazilian Corporate Governance Practices***

Pursuant to NYSE rules, foreign private issuers that are listed on the NYSE, such as our Company, must disclose any significant ways in which their corporate governance practices differ from those followed by U.S. companies under the listing rules of the NYSE.

The significant differences between our corporate governance practices and the NYSE corporate governance standards are as follows:

***Independence of Directors and Independence Tests***

The NYSE standards require a majority of the membership of listed company boards to be composed of independent directors and set for the criteria for determining independence. However, controlled companies (whether or not they are foreign private issuers) are not required to have a majority of the members of their board of directors be independent. Therefore, we would be exempt from this NYSE requirement even if we were a U.S. company.

The Brazilian Corporate Law and our bylaws require that our directors be elected by our shareholders at a general shareholders meeting. All our directors were appointed by our common shareholders and ten of such directors are independent in line with the parameters set by the regulations of B3's Novo Mercado.

Both the Brazilian Corporate Law and the CVM establish rules in relation to certain qualification requirements and restrictions, investiture, compensation, duties and responsibilities of companies' executives and directors. We believe these rules provide adequate assurances that our independent Directors are independent, although such rules allow us to have Directors that would not otherwise pass the independence tests established by the NYSE.

[**Table of Contents**](#TOC)

***Executive Sessions***

The NYSE standards require non-management directors of listed companies to meet at regularly scheduled executive sessions without management. In addition, our board of directors' internal rules set forth that the secretary of the board of directors shall summon regular meetings or sessions without the attendance of members of the Company's Board of Executive Officers even if they are a member of the board of directors.

According to the Brazilian Corporate Law, up to one-third of the members of our Board of Directors can be elected to executive positions. The remaining non-management directors are not expressly empowered to serve as a check on management, and there is no requirement that those directors meet regularly without management. Notwithstanding, our Board of Directors consists of eleven non-management directors.

***Nominating/Corporate Governance Committee Requirements***

The NYSE standards require that listed companies have a nominating/corporate governance committee composed entirely of independent directors, and such committee must have a written charter that addresses the committee's purposes and responsibilities (including certain required purposes and responsibilities) as well as the annual performance evaluation of the committee. However, controlled companies (whether or not they are foreign private issuers) are exempt from this requirement. Therefore, we would be exempt from this NYSE requirement even if we were a U.S. company.

Brazilian Corporate Law does not require us to maintain a committee responsible for nominations or corporate governance. Nevertheless, our board of directors has created our Nominations, Compensation and Corporate Governance Committee, which consists of three (3) to five (5) directors appointed by the Board of Directors to serve for the duration of their respective terms as members of our Board of Directors, two of which are independent in line with the parameters set by the regulations of B3's Novo Mercado. Our Nominations, Compensation and Corporate Governance Committee has a written charter, which sets forth its responsibilities, including examining proposals for nominations to our management team and assessing compensation limits for our management, establishing employment agreements for our management and examining corporate governance matters. Unlike the nominating/corporate governance committees of U.S. companies listed on the NYSE (other than controlled companies), our Nominations, Compensation and Corporate Governance Committee is not necessarily responsible for identifying individuals to become board members or overseeing the evaluation of the board and management. See "Item 6. Directors, Senior Management and Employees—C. Board Practices—Committees—Nominations, Compensation and Corporate Governance Committee" for a description of the responsibilities of our Nominations, Compensation and Corporate Governance Committee.

***Compensation Committee Requirements***

The NYSE standards require listed companies to have a compensation committee composed entirely of independent directors, and such members must meet the additional independence requirements specific to compensation committee membership set forth in the rules. In addition, NYSE standards require the compensation committee to have a written charter that addresses the committee's purposes and responsibilities (including certain required purposes and responsibilities). Said charter must specify the rights and responsibilities of the compensation committee regarding the authority to retain advisors and provide funding for such advisors. Certain specified factors must be considered regarding such advisers' independence from management. However, controlled companies (whether or not they are foreign private issuers) are exempt from this requirement. Therefore, we would be exempt from this NYSE requirement even if we were a U.S. company.

As noted above, while Brazilian Corporate Law does not require us to have a compensation committee, our Board of Directors has created our Nominations, Compensation and Corporate Governance Committee. As determined by the Brazilian Corporate Law, the compensation of management is approved by our shareholders at our shareholders' meeting. Subject to this approval, our Board of Directors establishes the compensation of its members and of our executive officers. The Nominations, Compensation and Corporate Governance Committee provides information and recommendations to the Board of Directors regarding the compensation of our executive officers and managers (see "Item 6. Directors, Senior Management and Employees—C. Board Practices—Committees—Nominations, Compensation and Corporate Governance Committee"). Our Nominations, Compensation and Corporate Governance Committee is not required to perform certain functions that are required of U.S. companies listed on the NYSE (other than controlled companies), such as directly reviewing and approving corporate goals and objectives relating to CEO compensation, evaluating the CEO's performance in light of those goals and objectives and, either as a committee or together with the other independent Directors, determining and approving the CEO's compensation level based on this evaluation.

[**Table of Contents**](#TOC)

Our Nominations, Compensation and Corporate Governance Committee is not required by the Brazilian Corporate Law or its charter to take into consideration any factors relevant to independence from management when retaining the advice of a compensation consultant, legal counsel or other advisers.

***Audit Committee Requirements***

The NYSE standards require listed companies (including foreign private issuers) to have an audit committee that satisfies the requirements of Rule 10A-3 under the Exchange Act. However, Rule 10A-3 provides an exemption for companies, such as our Company, that have a board of auditors or statutory auditors, established and selected pursuant to home country legal provisions expressly requiring or permitting such a board or similar body, provided that certain criteria are satisfied. The NYSE standards also set forth additional requirements for the audit committees of listed companies, including that the audit committee must have a minimum of three (3) members, all members of the audit committee must be independent, the audit committee must have a written charter that addresses certain topics, and each listed company must have an internal audit function. As a foreign private issuer, we are exempt from these additional requirements.

Brazilian Corporate Law and our bylaws each require that we have a statutory Fiscal Board (*Conselho Fiscal*). See "Item 6. Directors, Senior Management and Employees—C. Board Practices—Fiscal Board." Our statutory Fiscal Board meets the requirements of the general exemption from the listing standards for audit committees set forth in Exchange Act Rule 10A-3(c)(3). See "Item 16d. Exemptions from the Listing Standards for Audit Committees Procedures." Our statutory Fiscal Board is primarily charged with certain advisory, oversight and review functions with respect to the company's financial statements. However, the statutory Fiscal Board, as required by Brazilian Corporate Law, has only an advisory role and does not participate in the management of the company. Indeed, the decisions of the statutory Fiscal Board are not binding on the company under Brazilian Corporate Law. See "Item 6. Directors, Senior Management and Employees—C. Board Practices—Fiscal Board."

In addition to our statutory Fiscal Board, we have established a Control and Audit Committee as a best corporate governance practice to comply with the requirements of the Sarbanes-Oxley Act as described in "Item 6. Directors, Senior Management and Employees—C. Board Practices—Committees—Control and Audit Committee." Our Control and Audit Committee comprises a minimum of three (3) and a maximum of five (5) directors, who are not members of our Board of Executive Officers, and who are appointed by our Board of Directors to serve as members of the Control and Audit Committee for the duration of their respective terms as members of the Board of Directors. All members of our Control and Audit Committee are considered independent. The Committee has its own charter, which was approved by the board of directors.

***Shareholder Approval of Equity Compensation Plans***

NYSE rules require that shareholders be given the opportunity to vote on all equity compensation plans and material revisions thereto, with limited exceptions.

***Corporate Governance Guidelines***

NYSE rules require that listed companies adopt and disclose corporate governance guidelines.

We are subject to the corporate governance provisions of the Brazilian Corporate Law and of CVM Resolution 80/2022, which requires us to disclose certain corporate governance guidelines. Under CVM Resolution 80/2022, we must disclose information regarding our adoption of the governance practices set forth in the Brazilian Corporate Governance Code – Public Companies (the "Governance Code"). Thus, we are required to disclose a report named "Report on the Brazilian Corporate Governance Code – Public Companies" within seven months from the closing date of each fiscal year. Notwithstanding, since the governance practices set forth in the Governance Code are imposed only on a "comply or explain" basis, adherence to the recommendations described therein is not mandatory, however, an explanation must be disclosed with respect to any recommendations set forth therein that we do not adopt.

In addition, we have our corporate governance guidelines, which we disclose to the public on an annual basis.

**Corporate Governance Practices**

We are a *sociedade anônima*, a corporation incorporated under the laws of Brazil, and are subject to the corporate governance provisions set forth within Brazilian Corporate Law. We comply with the regulatory requirements of the Brazilian Corporate Law

[**Table of Contents**](#TOC)

regarding the independence of our board of directors, the establishment and composition of certain board committees and the adoption and disclosure of corporate governance guidelines.

We comply with several requirements of Brazilian and international laws to promote strong corporate governance, reduce investor uncertainties and enhance disclosure of material and other information.

With the approval of our board of directors and/or Officers, we implemented several measures over the last few years designed to improve our transparency and disclosure practices. We believe these measures will benefit our shareholders, and current and future investors as well as the marketplace in general. Among the measures we have implemented, we have:

● created a policy for disclosure of material facts or corporate actions and trading of our securities (*Política de Divulgação de Ato ou Fato Relevante e de Negociação de Valores Mobiliários*);

● created a policy for internal controls related to the Communication, Recording and Control of Financial and Accounting Information (*Normativa sobre Registro, Comunicação e Controle de Informação Financeiro-Contábil*);

● established the Quality and Sustainability Committee;

● established the Control and Audit Committee;

● established the Nominations, Compensation and Corporate Governance Committee;

● established the Strategy Committee;

● enacted a procedure to receive and deal with reports of accounting and auditing fraud within the company (*Canal de Denúncias*);

● enacted a policy for prior approval of contracting audit services (*Normativa sobre Aprovação Prévia de Serviços a serem Prestados pelo Auditor Externo*);

● enacted a code of business conduct and ethics (*Princípios de Negócio Responsável*);

● enacted a code of conduct for members of our finance team regulating the conduct of our managers in connection with the registration and control of financial and accounting information and their access to privileged and nonpublic information and data (*Normas de Conduta para Financeiros*);

● enacted a policy regarding communication of information to the securities market (*Normativa sobre Comunicação de Informação aos Mercados*); and

● enacted a policy regarding the prevention and fight against corruption (*Diretrizes de Prevenção e Combate à Corrupção and Política Anticorrupção*).

As determined by the Brazilian Corporate Law, the annual cap for the aggregate compensation of the Board of Directors and board of executive officers is approved by our shareholders at a shareholders' meeting. The Nominations, Compensation and Corporate Governance Committee provides information and recommendations to the board of directors regarding the criterion for compensation.

Our policy relating to insider trading currently in effect is determined pursuant to our *Política de Divulgação de Ato ou Fato Relevante e de Negociação de Valores Mobiliários* in accordance with corporate law. This document establishes practices for disclosing, using and preserving the confidentiality of relevant acts and/or facts of the Company, and establishes obligations and mechanisms for the disclosure of said facts to the market. The Company, controlling Shareholders, senior management, members of our Board of Directors, Fiscal Board and any other employee exposed to sensitive information are subject to the restrictions imposed by such rules. In addition to the prohibition on the trading of our shares by such individuals when in possession of insider information,

[**Table of Contents**](#TOC)

the rules establish blackout trading periods for those periods when insider information is available. In addition, the charter sets forth instructions for dealing with conflicts of interest and mandates disclosure of any such situation.

***Data Protection and Privacy Initiatives***

We are committed to ensuring security in the processing of our customers' personal data, and is guided by three fundamental pillars: confidentiality, integrity and availability of the information that we handle. As part of our commitment and in compliance with the applicable law, we have adopted robust security measures to prevent security incidents, and developed resources to identify and correct vulnerabilities that could put the privacy of our customers, employees and commercial partners at risk.

Our commitment to data protection and privacy predates the publication of the LGPD and has intensified since 2018, when we began adapting to the rules and obligations imposed by LGPD under the aegis of a specialized, multidisciplinary and capable workgroup. We highlight the following areas:

● *Data Protection Office*: in compliance with the LGPD, we appointed a Data Protection Officer and a Data Protection area solely dedicated to managing governance and raising awareness of the subject, actively advising business areas on issues and queries related to data protection/privacy and supporting the continuous evolution of the standards and measures in accordance with the LGPD.

● Information Security: Vivo has an Information Security Office, which centralizes all actions regarding the management system of information security, such as Digital Security, Identity and Access Management, Cyber Strategy, Risk Governance, Data Protection, Business Centric Security, Offensive Security, Cyber Defense, Cyber Monitoring, Cyber Incident Response Team, Fraud Prevention and Enterprise Physical Security. In the event of any security breach, the area controls the event and take corrective actions.

● *Legal*: Vivo has a qualified legal team that assists with the analysis of contracts, amendments and any legal issues that may arise about privacy and data protection.

In 2021, we also added to our corporate intranet, for access only by our employees, our Global Employee Privacy Notice, developed by our global team and applicable to all Telefónica group companies. The Global Employee Privacy Notice defines directives for the processing of data subjects' of our employees. Moreover, our data protection committee meets every two months, with participation from various areas of the Company. In addition, given our proactive stance, we actively engaged in discussions on data protection and privacy in Brazil with representative business groups, other companies in the industry, and independent stakeholders. As of the date of this annual report, we participated in all public consultations hosted by the Brazilian Data Protection Regulation Agency - ANPD by sending our contributions and recommendations to the ANPD. We are following the ANPD's regulatory calendar to develop our understanding of the LGPD.

In 2022, we carried out a new adaptation and change of format in our Privacy Center, in a project that was conducted jointly with other several companies of the Telefonica's group, so that we can create, in a unified way, a communication and transparency channel with the data subjects. Our Privacy and Transparency Center was created in 2016 and is available in Portuguese at https://www.vivo.com.br/a-vivo/informacoes-aos-clientes/centro-de-privacidade. We are one of the few large Brazilian companies to have created a dedicated website to bring transparency and provide information about our data protection and privacy actions, in addition to allowing the exercise of the rights of data subjects in an easy and free manner. The information on our website is not a part of this annual report on Form 20-F.

In addition to the new redesign of our Privacy Center, we have also updated our Privacy Policy, making it more complete and providing clearer and more accurate information about our data processing practices for data subjects.

Moreover, under the organization of Conexis Brazil and together with other telecom companies operating in the country, in 2022, was launched the Code of Best Practices on Data Protection for the Telecommunications Sector in Brazil, available in Portuguese at https://conexis.org.br/wp-content/uploads/2022/08/LGPDBoasPraticasDispositivosMoveis.pdf. The document brings together protocols that must be adopted to ensure compliance with the LGPD, the result of the knowledge accumulated by companies since the publication of the law and the initiatives adopted by them to comply with the law and, at the same time, ensure the continuity of the provision of connectivity services.

**Conversion of Our Preferred Shares into Common Shares**

As mentioned above, on October 1, 2020, our shareholders approved, and our preferred shareholders ratified, the conversion of all our preferred shares into common shares, in the proportion of one common share for each one preferred share. After the concession and the expiration of the term for shareholders to exercise withdrawal rights, we proceeded with the Conversion, and the last trading session for our preferred shares on the B3 and for our ADSs backed by preferred shares on the NYSE was on November 20, 2020. Therefore, as of November 23, 2020, "VIVT3" represents the only ticker symbol for the trading of the Company's common shares on the B3, and ADSs backed by our common shares began trading on the NYSE under the ticker symbol "VIV." The Conversion was undertaken as part of certain improvements to our corporate governance practices, in order to maximize the generation of value to all our shareholders, conferring to them rights set forth under Brazilian Corporate Law, such as the right to vote and the right to tag along, among others.

#### Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders

Telefônica Brasil S.A.

***Opinions on the Financial Statements and Internal Control over Financial Reporting***

We have audited the accompanying consolidated balance sheets of Telefônica Brasil S.A. and its subsidiaries (the "Company") as of December 31, 2022 and December 31, 2021, and the related consolidated statements of income, other comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2022, including the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in *Internal Control - Integrated Framework* (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and December 31, 2021**,** and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in *Internal Control - Integrated Framework* (2013) issued by the COSO.

***Basis for Opinions***

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Annual Report on Internal Control over Financial Reporting appearing under Item 15. Our responsibility is to express opinions on the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As described in Management's Annual Report on Internal Control over Financial Reporting, management has excluded Garliava RJ Infraestrutura e Redes de Telecomunicações S.A. ("Garliava") from its assessment of internal control over financial reporting as of December 31, 2022 because it was acquired by the Company in a purchase business combination during 2022. We have also excluded Garliava from our audit of internal control over financial reporting. Garliava is a wholly-owned subsidiary whose total assets and total revenues excluded from management's assessment and our audit of internal control over financial reporting represent 1.4% and 2.3%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2022.

[**Table of Contents**](#TOC)

***Definition and Limitations of Internal Control over Financial Reporting***

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) 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.

***Critical Audit Matters***

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

&nbsp;&nbsp;&nbsp;&nbsp;● **Business combination – valuation of intangible assets acquired and contingent liabilities assumed in connection with the Garliava RJ Infraestrutura e Redes de Telecomunicações S.A. ("Garliava") acquisition** 

As described in Note 2d.6 to the consolidated financial statements, the Company completed the acquisition of Garliava for total consideration of R$5,491,584 thousand. As of the acquisition date, the Company recognized separately from goodwill, identifiable intangible assets acquired and contingent liabilities assumed related to (i) licenses, (ii) customer portfolio and (iii) contingent liabilities valued at R$2,518,836 thousand, R$96,195 thousand and R$453,697 thousand, respectively. Management applied significant judgment in estimating the fair value of these intangible assets acquired and contingent liabilities assumed, which involved the use of significant estimates and assumptions with respect to the average revenue per user ("ARPU"), projected operating margin, useful life, churn rate and discount rate, as well as the probability of loss and expected cash flows as related to certain lawsuits in determining the fair value of the contingent liabilities.

The principal considerations for our determination that performing procedures relating to the Garliava acquisition is a critical audit matter are (i) there was a high degree of auditor judgment and subjectivity in performing procedures relating to the fair value of intangible assets acquired and contingent liabilities assumed due to the significant amount of judgment by management when developing the estimate; (ii) the significant audit effort in evaluating the significant assumptions related to the ARPU, projected operating margin, useful life, churn rate, discount rate, as well as the probability of loss and expected cash flows as related to certain lawsuits; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

[**Table of Contents**](#TOC)

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the acquisition accounting, including controls over management's valuation of the intangible assets acquired and contingent liabilities assumed and controls over the development of significant assumptions related to the ARPU, projected operating margin, useful life, churn rate, discount rate, and the probability of loss and expected cash flows of certain lawsuits. These procedures also included, among others (i) reading the purchase agreement related to the acquisition of Garliava and (ii) testing management's process for estimating the fair values of intangible assets acquired and contingent liabilities assumed. Testing management's processes included evaluating appropriateness of the valuation methods, testing the completeness and accuracy of data provided by management, and evaluating the reasonableness of significant assumptions used for the purposes of estimating the fair values. Evaluating the reasonableness of the main assumptions adopted includes considering (i) the past performance of the acquired business, as well as economic and industry forecasts applied for ARPU, projected operating margin, useful life and churn rate; (ii) the cost of capital of comparable business and other industry factors for the discount rate and (iii) the probability of loss and expected cash flows as related to certain lawsuits of the possible and remote lawsuits for the fair value calculation of contingent liabilities. Professionals with specialized skill and knowledge were used to assist in evaluating Company's valuation methods.

&nbsp;&nbsp;&nbsp;&nbsp;● **Provision for tax litigations and regulatory contingencies** 

As described in Notes 8(g) and Note 20 to the consolidated financial statements, the Company has (i) recorded provision for tax (income tax and other taxes) and regulatory contingencies of R$2,587,865 thousand and R$1,869,035 thousand, respectively, as of December 31, 2022, (ii) disclosed liabilities related to tax and regulatory litigation in the amount of R$33,472,824 thousand and R$5,844,624 thousand respectively, and related to uncertain income tax position under discussion with tax authorities in the amount of R$29,777,824 thousand, as of December 31, 2022. The Company recognizes provision in the consolidated financial statements for the pending litigation when the Company has a present obligation as a result of a past event, management determined that a loss is probable, and the amount of the loss can be reasonably estimated. No provision for tax litigation is recognized in the consolidated financial statements for unfavorable outcomes when, after assessing the information available, (i) management concludes that it is not probable that a loss has been incurred in any of the pending litigation; or (ii) management is unable to estimate the loss of the pending matters. In the case of income tax pending litigations, management determines whether it is probable or not that the taxation authority will accept the uncertain tax treatment. If the Company concludes it is not probable that taxation authority will accept the uncertain tax treatment, a provision for income tax is recognized. The Company also discloses the tax and regulatory contingencies in circumstances where management concludes (i) no loss is probable or reasonably estimable, but it is reasonably possible that a loss may be incurred or, (ii) in case of income tax pending litigations, it is probable that the taxation authority will accept the uncertain tax treatment.

The principal considerations for our determination that performing procedures relating to tax and regulatory contingencies is a critical audit matter are the significant judgment by management when assessing the likelihood of a loss being incurred and when determining whether a reasonable estimate of the loss and possible outcomes for each claim can be made, which in turn led to a high degree of auditor judgment, effort, and subjectivity in evaluating management's assessment of the loss contingencies associated with litigations claims.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management's evaluation of pending litigation, including controls over determining whether a loss is probable and whether the amount of loss can be reasonably estimated or whether it is probable the taxation authority will accept the income tax pending litigations, as well as financial statement disclosures. These procedures also included among others, (1) obtaining and evaluating the letters of audit inquiry with internal and external legal counsel, (2) evaluating the reasonableness of management's assessment regarding unfavorable outcomes, and (3) evaluating the sufficiency of the Company's disclosures. Professionals with specialized skill and knowledge were used to assist in the evaluation of Company's assessment regarding unfavorable outcomes.

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;● **Revenue recognition - unbilled** 

As described in Notes 5 and 25 to the consolidated financial statements, of the total revenue recognized by the Company for the year ended December 31, 2022, R$2,339,241 thousand to be billed to customers in note (5c). When the revenue billing cycle does not align with the account closing date, management estimates the amount to be recognized for services rendered and not yet billed at the year-end. These estimates are based on different cycles of information, on data obtained from different sources and processed by a large number of applications and systems.

The principal considerations for our determination that performing procedures relating to unbilled revenue is a critical audit matter are the significant judgments made by management for estimating the amount of unbilled revenue. This in turn led to a high degree of auditor judgment and effort in performing audit procedures to evaluate unbilled revenue recognition.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to unbilled revenue recognition. The procedures also included, among others (1) assessing the reasonableness of the criteria employed by management to estimate revenue rendered and not yet billed including the accuracy of the underlying data and (2) performing a comparison of the originally estimated and actual billed revenue after year-end.

&nbsp;&nbsp;&nbsp;&nbsp;● **Goodwill impairment assessment** 

As described in Note 14 to the consolidated financial statements, the Company's consolidated goodwill balance was R$26,361,829 thousand as of December 31, 2022, associated with a single Cash-Generating Unit (CGU) that provides telecommunications services through a broadly integrated network. As described in Note 15, management conducts impairment tests for goodwill at least annually or more frequently, if events or circumstances indicate the carrying amount may not be fully recoverable. Potential impairment is identified by comparing the value in use of the CGU to its carrying value, including goodwill. Value in use is estimated by management using a discounted cash flow model. Management's cash flows projections for the CGU included significant judgements and assumptions relating to revenue growth, discount rate and perpetuity growth rate.

The principal considerations for our determination that performing procedures relating to goodwill impairment assessment is a critical audit matter are (i) the significant judgments made by management when developing the value in use measurement of the CGU; (ii) a high degree of auditor judgement, subjectivity and effort in performing procedures and evaluating management's significant assumptions related to revenue growth and discount rate; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management's goodwill impairment assessment, including controls over the valuation of the CGU. These procedures also included, among others, (i) testing management's process for developing the value in use estimate; (ii) evaluating the appropriateness of the discounted cash flow model; (iii) testing the completeness and accuracy of underlying data used in the model; and (iv) evaluating the reasonableness of the significant assumptions used by management related to revenue growth, discount rate and perpetuity growth rate. Evaluating management's assumption related to revenue growth involved evaluating whether the assumption used by management was reasonable includes considering (i) the current and past performance of the CGU, (ii) the consistency with external market and industry data, and (iii) whether this assumption was consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in the evaluation of the Company's discounted cash flow model and the discount rate and the perpetuity growth rate assumptions.

Telefônica Brasil S.A. (the "Company" or "Telefônica Brasil") is a publicly-held corporation whose main corporate purpose is operating telecommunications services; development of activities necessary or complementary to the execution of such services, in accordance with the concessions, authorizations and permissions granted; rendering value-added services; offering integrated solutions, management and provision of services related to: (i) data centers, including hosting and co-location; (ii) storage, processing and management of data, information, texts, images, videos, applications and information systems and similar; (iii) information technology; (iv) information and communication security; and (v) electronic security systems; licensing and sublicensing of software of any nature, among others.

The Company's principal offices are located at 1376, Engenheiro Luis Carlos Berrini Avenue, in the city and state of São Paulo, Brazil. It is a member of the Telefónica Group ("Group"), based in Spain which operates in several countries across Europe and Latin America.

On December 31, 2022, Telefónica S.A. ("Telefónica"), the Group holding company, held a total direct and indirect interest in the Company of 74.20% (73.58% on December 31, 2021), Note 24.a.

The Company is registered with the Brazilian Securities Commission ("CVM") and its shares are traded on the B3. It is also registered with the U.S. Securities and Exchange Commission ("SEC") and its American Depositary Shares ("ADSs"), backed by its common shares, are traded on the New York Stock Exchange ("New York Stock Exchange"-"NYSE").

**b) Operations**

The Company renders services for: (i) Fixed Switched Telephone Service Concession Arrangement ("STFC"); (ii) Multimedia Communication Service ("SCM", data communication, including broadband internet); (iii) Personal Mobile Service ("SMP"); and (iv) Conditioned Access Service ("SEAC" - Pay TV) and (v) Private Limited Service ("SLP"), throughout Brazil, through concessions and authorizations, in addition to other activities.

Service concessions and authorizations are granted by Brazil's Telecommunications Regulatory Agency ("ANATEL"), the agency responsible for the regulation of the Brazilian telecommunications sector under the terms of Law No. 9472 of July 16, 1997 - General Telecommunications Law ("Lei Geral das Telecomunicações" - LGT).

In accordance with the STFC service concession agreement, every two years, over the life of the agreement's 20-year term ending on December 31, 2025, the Company will pay a fee equivalent to 2% of its prior-year STFC revenue, net of applicable taxes and social contribution taxes (Note 23).

Before Law no. 13.879 / 2019 came into effect authorizations for the use of radio frequencies were commonly granted for 15 years and could be extended only once, for the same term. Following the normative changes in the aforementioned Law, successive extensions of authorization grants were allowed, though applicability to the current terms was only clarified by Decree no. 10.402 / 2020, which detailed the requirements related to the new successive extension regime and that the current authorizations are also covered by the new regime.

The Decree defined ANATEL's parameters for evaluating the scope of extension requests, such as ensuring the efficient use of radio frequencies, competitive aspects, meeting the public interest and fulfilling obligations already assumed with ANATEL.

[**Table of Contents**](#TOC)

Currently, each two years, following the first extension, the Company must pay a charge equivalent to 2% of revenues earned through the SMP provision in the year prior, net of taxes and social contributions (Note 23), and for certain terms, in the 15th year, the Company will pay only the equivalent of 1% of its prior-year revenue. The calculation considers the net revenue from Basic and Alternative Service Plans. In July 2018, ANATEL published Resolution No. 695 with a new public spectrum price regulation. This Resolution established new criteria for the costs of license extensions. The formula includes the authorization time, regional revenue and the spectrum used by the provider. Part of the payment can be converted into investment commitments.

Further details of the Company's licenses/authorizations are presented in Note 14.

#### 2) BASIS OF PREPARATION AND PRESENTATION OF FINANCIAL STATEMENTS
**a) Statement of compliance**

Assets and liabilities are classified as current when it is probable that their realization or settlement will occur in the next 12 months (normal operating cycle). Otherwise, they are classified and shown as non-current. The only exception relates to the balances of deferred tax assets and liabilities, which are classified and fully shown as non-current.

The Statement of Cash Flows was prepared in accordance with IAS 7 - Statement of Cash Flows and reflects the changes in cash that occurred in the years presented using the indirect method.

**d) Corporate events in 2021 and 2022**

*d.1) FiBrasil Operation*

On July 2, 2021, the Company, after approval by its Board of Directors on March 2, 2021 and upon obtaining the drelevant regulatory authorizations, concluded the agreements with the Caisse de dépot et placement du Québec ("CDPQ"), a global investment group, and with Telefónica Infra, SLU ("TEF Infra"), a company headquartered in Spain, wholly-owned by Telefónica SA, the Company's controlling Shareholder, for the construction, development of a neutral and independent fiber optic network in the Brazilian market through FiBrasil Infraestrutura e Fibra Ótica SA ("FiBrasil") ("Transaction").

[**Table of Contents**](#TOC)

The DOU on April 6, 2021, published a decision of the General Superintendence of Administrative Council for Economic Defense ("CADE") which approved without restrictions the joint venture agreement between the Company, TEF Infra and CDPQ, by FiBrasil. On April 23, 2021, the period for filing an appeal or summons having expired, CADE certified the final and unappealable decision with the unrestricted approval of the decision of the General Superintendence of CADE of April 6, 2021. In analyzing the merger, CADE's General Superintendence did not raise anti-competitive concerns. It noted that the operation may stimulate competition by unbundling services, in part, between the Company and FiBrasil, for fiber networks as infrastructure for telecommunications and wholesale services for other telecommunications service providers.

As TEF Infra is part of the Telefónica Group (Spain), this Transaction was subject to approval by the European Union's antitrust authority, which was granted on April 22, 2021.

On June 7, 2021, ANATEL granted prior consent to the implementation of the Transaction, so that, on September 23, 2021, an ordinatory order was issued determining the shelving of the prior consent process, since its purpose was exhausted, as provided for in ANATEL's Bylaws.

The Company, as an anchor customer of FiBrasil, follows its growth strategy in the fiber market, leveraging the cross selling of services to its customers, maximizing the return on invested capital and consolidating itself as the leading convergent operator in the country.

IFRS 10 contain guidance on accounting for changes in interest in subsidiaries when control is lost. In this case, the rule establishes that the retained interest must be valued at its fair value (based on the sales price) and any difference must be recorded in income (in addition to the write-off of the portion sold). The Telefónica Group has adopted this to register the Transaction in its subsidiaries (Company and TEF Infra).

The following are the accounting effects arising from the closing of the Transaction, which took place on July 2, 2021:

[**Table of Contents**](#TOC)

The assumptions, critical judgments, methods and hypotheses used by the Company to determine these fair values were as follows:

Licenses

The fair value of the licenses was determined using the discounted cash flow method under the Income Approach, which considers the income-earning capacity of the identified asset or business. The premise for this approach is that the value of an asset or business can be measured as being equivalent to the present value of the net economic benefit (cash receipts minus cash expenses) to be received over its useful life. The fair value allocated to the licenses on the acquisition date was R$2,518,836, which is being amortized over the average term of 10.08 years, ranging from 5 years to 15 years.

The main assumptions used in the assessment of the licenses were: (i) Revenues: based on the number of existing active customers migrated from Oi to Garliava, as well as the average revenue per user ("ARPU"), considering an estimated loss of annual customers of 9% per year, on average; (ii) Costs and Expenses: were projected in accordance with historical data obtained by the Company and expectations of normalization of the operating margin in the long term. The projections were based on fixed and variable percentages of expenses, adjusting the fixed portion according to inflation and the variable according to revenue; (iii) Oibda Margin: vary between 35.3% in 2022 and 54.5% in 2030. The observed margin gains are due to gains in scale of the operation, improvements in efficiency, operational synergies to be achieved by merging operations of Garliava within the Company; iv) Depreciation: represents an average of 9.2% of net operating revenue; Tax rate: 34%, according to Brazilian tax legislation; and (v) After-tax discount rate: 12.4%.

Customer portfolio

The customer portfolio was valued using the MEEM method ("Multi-period Excess Earnings Method"), which is based on a calculation of discounting cash flows from future economic benefits attributable to the customer base, net of eliminations of the implied contribution obligations. To estimate the remaining useful life of the customer base, an analysis was made of the average duration of customer relationships using a churn rate.

The purpose is to estimate a lifetime curve that predicts future turnover profiles associated with the current customer base. As an approximation for the customer life curve, the so-called "Iowa curves" were considered. The fair value allocated to the customer portfolio on the acquisition date was R$96,195, which will be amortized on a straight-line basis, according to the useful life of each type of customer, over an average term of 6.60 years, ranging from 5 years to 8 years.

The main assumptions used in assessing the customer portfolio were: (i) Customers: 5 relationships with customers were evaluated, namely: B2C prepaid, B2C postpaid, B2C Control, B2B postpaid and B2B M2M; (ii) Revenue: based on the number of existing customers by type, migrated from Oi to Garliava, as well as the ARPU charged for providing the service. In the revenue projection, an estimate of annual customer loss and ARPU stability were considered; (iii) Churn rate: was calculated based on the historical percentage of customers leaving, ranging from 26.8% to 50.2%; (iv) Costs and expenses: were projected in accordance with historical data obtained by the Company and expectations of normalization of the operating margin in the long term and operating synergies to be realized by the merger of Garliava's operations within the Company. The projections were based on fixed and variable percentages of expenses, adjusting the fixed portion according to inflation and the variable according to revenue, considering an add-back of 97% of marketing expenses, to reflect the exclusion expenses related to obtaining new customers, based on market standards; (v) Tax rate: 34%, pursuant to Brazilian tax legislation; and (v) after-tax discount rate: 12.4%.

Fair Value of Contingent Liabilities

Under IFRS 3(R) Business Combinations, the acquirer recognizes, at the acquisition date, contingent liabilities assumed in a business combination even when it is not probable that an outflow of resources will be required to settle the obligation, provided that it is a present obligation that arises from past events and its fair value can be measured reliably. Contingent liabilities at fair value of R$453,697 were recognized from this acquisition, which were determined based on the estimated cash outflow for settlement on the acquisition date.

[**Table of Contents**](#TOC)

The Transaction may reach the amount of up to R$120,000, subject to the achievement of operational and financial metrics agreed between the parties. Said price was supported by an appraisal report prepared by an independent company. The Transaction documents contain terms and provisions common to this type of transaction, such as representations and warranties, indemnification and others. The Operation was preceded by a financial, administrative, legal, fiscal and operational diligence in relation to Vita IT.

The Transaction is part of the Company's strategy to strengthen its performance and positioning in the networking market, with the supply of network equipment (example: switches, routers and Wi-Fi access points) and implementation, management and technical support services for the corporate network of companies.

With the completion of the Transaction on October 3, 2022, TIS became the direct parent company of Vita IT. Vita IT is headquartered in Brazil and operates as a solution integrator for companies of different sizes, providing professional and managed networking services, as well as hardware and software resale. The combination of resources and capabilities of TIS and Vita IT will generate added value for the Company's client portfolio, thanks to the performance of both companies under the same management in information technology and networking activities. The Operation will also make it possible to leverage new businesses on a larger scale and in a sustainable manner, in addition to enabling revenue growth and improving the business margin. The integration plan between Vita IT, TIS and the Company was designed to preserve its value and give continuity to Vita IT's business.

Pursuant to IFRS 3 (R) - Business Combinations, business acquisitions are accounted for using the acquisition method. The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the fair values of assets acquired and liabilities assumed on the acquisition date from the acquiree's former controlling shareholders and any interests issued in exchange for control of the acquiree.

On the date of these consolidated financial statements of the Company, TIS is in the process of finalizing the report for allocation of the purchase price (Purchase Price Allocation - PPA), through the analysis of the determination of the fair value of the identifiable assets acquired and the assumed liabilities of Vita IT. It is estimated that this final analysis will be completed as soon as Management has all the relevant information on the facts, not exceeding a maximum period of 12 months from the acquisition date.

Interest held in subsidiaries or joint ventures is measured under the equity method in the individual financial statements. In the consolidated financial statements, investments and all asset and liability balances, revenues and expenses arising from transactions and equity interest in subsidiaries are eliminated entirely. Investments in joint ventures are measured under the equity method in the consolidated financial statements.

[**Table of Contents**](#TOC)

Information on the investees is presented in Note 12.

**f) Segment reporting**

Business segments are defined as components of a company for which separate financial information is available and regularly assessed by the operational decision-making professional in definition of how to allocate funds to an individual segment and in the assessment of segment performance. Considering that: (i) all officers and managers' decisions are based on consolidated reports; (ii) the Company and its subsidiaries' mission is to provide their customers with quality telecommunications services; and (iii) all decisions related to strategic planning, finance, purchases, short- and long-term investments are made on a consolidated basis, the Company and its subsidiaries operate in a single operating segment, namely the provision of telecommunications services.

**g) Significant accounting practices**

Significant and relevant accounting policies for the understanding of the basis of recognition and measurement applied in the preparation of the Company's financial statements are included in the respective notes to which they refer.

The accounting policies adopted in the preparation of the consolidated financial statements for the year ended December 31, 2022 are consistent with those used in the preparation of the consolidated annual financial statements for the year ended December 31, 2021, except for the changes required by the new pronouncements, interpretations and amendments, approved by the International Accounting Standards Board (IASB), which are effective from January 1, 2022, as follows:

● IAS 16 – Property, plant and equipment: The amendment prohibits entities from deducting from the cost of a property, plant and equipment any proceeds from sales of items produced by bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, an entity recognizes the products of selling the items, and the costs of producing the items, in the income statement.

● IFRS 3 – Business Combinations – Amendments to references to the Conceptual Framework: The amendments replace a reference to a previous version of the IASB Conceptual Framework with a reference to the current version issued in March 2018 without significantly changing its requirements. The amendments add an exception to the recognition principle of IFRS 3 to avoid issuing potential 'day 2' gains or losses arising from liabilities and contingent liabilities that would be within the scope of IAS 37 or IFRIC 21, if incurred separately. The exception requires entities to apply the criteria of IAS 37 or IFRIC 21, respectively, instead of the Conceptual Framework, to determine whether a present obligation exists at the acquisition date. The amendments also add a new paragraph to IFRS 3 to clarify that contingent assets do not qualify for recognition on the acquisition date.

● IAS 37 – Provisions, Contingent Liabilities and Contingent Assets – Onerous contracts: An onerous contract is a contract under which the unavoidable costs of fulfilling the obligations arising from the contract (ie the costs that the entity cannot avoid because it has the contract) exceed the expected economic benefits to be received. The amendments specify that, when assessing whether a contract is onerous or loss-making, an entity needs to include costs that directly relate to a contract to provide goods or services, including incremental costs (for example, direct labor costs and materials) and an allocation of costs directly related to contract activities (for example, depreciation of equipment used to fulfill the contract and costs of managing and supervising the contract). General and administrative costs are not directly related to a contract and are excluded unless explicitly charged to the counterparty under the terms of the contract.

● IFRS 9 Financial Instruments - Rates in the '10 per cent' test for derecognition of financial liabilities: The amendment clarifies the rates that an entity includes when assessing whether the terms of a new or modified financial liability are materially different from the terms of the financial liability original. These fees include only fees paid or received between the borrower and the lender, including fees paid or received by the borrower or the lender on behalf of the other.

The adoption of these amendments did not have any impact on the individual and consolidated financial statements in the initial period of adoption (January 1, 2022).

[**Table of Contents**](#TOC)

New IFRS pronouncements, issues, amendments and interpretations of the IASB

The new and amended standards and interpretations issued, but not yet effective up to the date of issue of the Company's financial statements, are described below. The Company intends to adopt these new and amended standards and interpretations, if applicable, when they become effective.

● Amendment to IAS 12 - Deferred tax related to assets and liabilities arising from a single transaction: In May 2021, the IASB released amendments to IAS 12, which restrict the scope of the initial recognition exception under IAS 12, so that it does not applies more to transactions that give rise to equal taxable and deductible temporary differences. The changes shall apply to transactions occurring in annual periods beginning on or after the earliest comparative period presented. In addition, at the beginning of the earliest comparative period presented, a deferred tax asset (provided there is sufficient taxable profit available) and a deferred tax liability should also be recognized for all deductible and taxable temporary differences associated with leases and decommissioning obligations. This rule change is effective for fiscal years beginning on/or after January 1, 2023.

● Amendments to IAS 1: Classification of liabilities as current or non-current: In January 2020, the IASB issued amendments to IAS 1, in order to specify the requirements for classifying liabilities as current or non-current. The amendments clarify: (i) what is meant by a right to postpone settlement; (ii) that the right to postpone must exist on the base date of the report; (iii) that classification is not affected by the likelihood that an entity will exercise its right of postponement; and (iv) that only if a derivative embedded in a convertible liability is itself an equity instrument would the terms of a liability not affect its classification. The changes are effective for periods beginning January 1, 2023 and must be applied retrospectively.

● Amendments to IAS 8: Definition of accounting estimates: In February 2021, the IASB issued amendments to IAS 8, which introduces the definition of 'accounting estimates'. The amendments clarify the distinction between changes in accounting estimates and changes in accounting policies and error correction. In addition, they clarify how entities use measurement techniques and inputs to develop accounting estimates. The amendments will be effective for periods beginning on or after January 1, 2023 and will apply to changes in accounting policies and estimates that occur on or after the beginning of that period.

● Amendments to IAS 1 and IFRS Practice Statement 2: Disclosure of Accounting Policies; In February 2021, the IASB issued amendments to IAS 1 and IFRS Practice Statement 2 Making Materiality Judgments, which provide guides and examples to help entities apply materiality judgments to the disclosure of accounting policies. The amendments are to help entities disclose accounting policies that are more useful by replacing the requirement to disclose significant accounting policies for material accounting policies and adding guidance for how entities should apply the concept of materiality to make decisions about policy disclosures. accounting. Amendments to IAS 1 are applicable for periods beginning on or after January 1, 2023 with early adoption permitted. Since amendments to Practice Statement 2: Making Materiality Judgments provide non-mandatory guidance on applying the definition of material to accounting policy information, an adoption date for this amendment is not required.

The Company estimates that the adoption of these standards and amendments will not have a significant impact on the individual and consolidated financial statements in the initial period of adoption (January 1, 2023).

The Company does not anticipate the early adoption of any pronouncement, interpretation or amendment that has been issued before application is mandatory.

**h) Significant accounting judgments estimates and assumptions**

The preparation of the financial statements requires the use of certain critical accounting estimates and the exercise of judgment by the Company's management in applying its accounting policies. These estimates are based on experience, knowledge, information available at the end of the year, and other factors, including expectations of future events that are believed to be reasonable in the circumstances. Actual results involving these estimates could differ in values from those recorded in the financial statements due to the criteria inherent in the estimation process. The Company reviews its estimates at least annually.

[**Table of Contents**](#TOC)

The significant and relevant estimates and judgments applied by the Company in the preparation of these financial statements are presented in the following notes: trade accounts receivable (Note 5); income and social contribution taxes (Note 8); property, plant and equipment (Note 13); intangible assets (Note 14); provision and contingencies (Note 20); net operating income (Note 25); pension plans and other post-employment benefits (Note 31); and financial instruments and risk and capital management (Note 32).

#### 3) CASH AND CASH EQUIVALENTS
**a) Accounting policy**

These are financial assets, measured at amortized cost, maintained in order to meet short-term cash commitments and not for investment or other purposes. The Company and its subsidiaries consider cash equivalents a short-term investment readily convertible into a known amount of cash and subject to insignificant risk of change in value and when redeemable within 90 days.

#### 5) TRADE ACCOUNTS RECEIVABLE
**a) Accounting policy**

These are financial assets measured initially at fair value and subsequently, at amortized cost and are evaluated by the value of the services provided and goods sold in accordance with the contracted conditions, net of estimated impairment losses. These include the services provided to customers, which were still not billed at the balance sheet date, as well as other trade accounts receivable related to the sale of cell phones, SIM cards, accessories, advertising and rent of IT equipment ("Vivo Tech" product) and credit rights of the Vivo Money FIDC.

The Company measures the provision for estimated impairment losses in an amount equal to the loss of credit expected for a lifetime.

**b) Critical estimates and judgments**

In determining whether the credit risk of a financial asset has increased significantly since the initial recognition and in estimating the expected credit losses, the Company considers reasonable and bearable information that is relevant and available. This includes quantitative and qualitative information and analysis, based on the Company's historical experience, credit assessment and considering forward-looking information. Although the Company believes that the assumptions used are reasonable, the results may be different.

#### 6) INVENTORIES
**a) Accounting policy**

These are evaluated and presented at the lower of average acquisition cost and net realizable value, whichever is lower. These include resale materials such as cellphones, SIM cards, accessories, consumption materials and maintenance. Net realizable value is the estimated selling price in the ordinary course of business, less estimated costs to sell.

Estimated impairment losses are set up for materials and devices considered obsolete or whose carrying amounts are in excess of those usually sold within a reasonable period. Additions and reversals of estimated impairment losses and inventory obsolescence are included in cost of goods sold (Note 26).

**8) INCOME AND SOCIAL CONTRIBUTION TAXES**

**a) Accounting policy**

a.1) Current taxes

Current tax assets and liabilities are measured at the estimated amount recoverable from, or payable to, the tax authorities. The tax rates and laws used in calculating the amounts referred to above are those in effect, or substantially in effect, at year-end. In the balance sheet, current taxes are presented net of prepayments over the year.

[**Table of Contents**](#TOC)

Current income and social contribution taxes, related to items directly recognized in equity, are also recognized in equity. Management regularly assesses the tax position in circumstances in which tax regulation requires interpretation and sets up provision therefore when appropriate.

a.2) Deferred taxes

Deferred tax is generated by temporary differences at the balance sheet date between the tax bases of assets and liabilities and their carrying amounts.

Deferred tax assets are recognized for all deductible temporary differences, unused tax credits and losses, to the extent that taxable profit is likely to be available for realization of deductible temporary differences and unused tax credits and losses are likely to be used, except: (i) when the deferred tax asset related to the deductible temporary difference arises from initial recognition of an asset or liability in a transaction other than a business combination and does not impact, at the transaction date, the book profit, income or loss for tax purposes; and (ii) on deductible temporary differences related to investments in subsidiaries that deferred tax assets are recognized only to the extent that it is probable that temporary differences will be reversed in the near future and taxable profit is likely be available so that temporary differences can be used.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit shall be available to allow all or part of the deferred tax asset to be used. Derecognized deferred tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

Deferred tax liabilities are recognized on all temporary tax differences, except: (i) when the deferred tax liability arises from initial recognition of non-deductible goodwill, or an asset or liability in a transaction other than a business combination, and does not affect book profit or taxable profit or tax losses on the transaction date; and (ii) on temporary tax differences related to investments in subsidiaries, in which the temporary difference reversal period can be controlled and temporary differences are not likely to be reversed in the near future.

Deferred tax assets and liabilities are measured at the tax rate expected to be applicable for the year the asset will be realized, or the liability will be settled, based on the rates provided in tax legislation and that were published as at year-end.

Deferred tax assets and liabilities are not discounted to present value and are classified in the balance sheet as non-current, irrespective of their expected realization.

The tax effects of items recorded directly in equity are also recognized in equity. Deferred tax items are recognized based on the transaction which gave rise to that deferred tax, in comprehensive income or directly in equity.

Deferred tax assets and liabilities are presented net when there is a legal or constructive right to offset a tax asset against a tax liability and deferred taxes relate to the same taxpaying entity and are subject to the same tax authority.

**b) Critical estimates and judgments**

There are uncertainties regarding the interpretation of complex tax regulations and the amount and timing of future taxable profits. The Company and its subsidiaries set up provision, based on estimates, for possible consequences of different interpretation by the tax authorities. The amount of this provision is based on various factors, such as previous tax audit experience and different interpretations of tax regulations by the taxable entity and by the relevant tax authority. Such differences in interpretation may arise on a wide variety of issues depending on the conditions prevailing in the respective domicile of the Company or those of its subsidiaries.

The Company and its subsidiaries evaluate the recoverability of deferred tax assets based on estimates of future profits. This recoverability ultimately depends on the ability to generate taxable profits over the period in which the deferred tax asset is deductible. The analysis considers the reversal period of deferred tax liabilities, as well as estimates of taxable profits, based on updated internal projections reflecting the latest trends.

[**Table of Contents**](#TOC)

Determining the proper classification of the tax items depends on several factors, including an estimate of the period and the realization of the deferred tax asset and the expected date of payments of these taxes. The actual flow of receipt and payment of income tax could differ from estimates made by the Company and its subsidiaries, as a result of changes in tax laws or of unexpected future transactions that may have an impact on tax balances.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Under Brazilian tax legislation these may be offset up to 30% of the annual taxable income but otherwise have no expiry date.

In 2021, the Company recognized R$1,405,565 in deferred income tax and social contribution assets, arising from the decision of the Federal Supreme Court ("STF") in an Extraordinary Appeal determining that interest received on receivables for overpaid taxes should not be subject to Income Tax and Social Contribution (Note 8.f).

&nbsp;&nbsp;&nbsp;&nbsp;(2) Amounts that will be realized upon payment of provision, occurrence of impairment losses for trade accounts receivable, or realization of inventories, as well as upon reversal of other provision.

(3)Refers to deferred taxes arising from the disposal of CloudCo Brasil and IoTCo Brasil in 2021 (note 2.d),

e.2) Unrecognized tax credits

On December 31, 2022, deferred tax assets (income and social contribution tax losses) were not recognized in the subsidiaries' (POP, Recicla V, TGLog and TIS) accounting records, in the amount of R$75,003 (R$71,126 on December 31, 2021), as it is not probable that future taxable profits will be sufficient for offset for these subsidiaries to benefit from such tax credits.

**f) Reconciliation of income tax and social contribution expense**

The Company and its subsidiaries recognize income and social contribution taxes on a monthly basis, on an accrual basis, and pay taxes based on estimates, as per the tax auxiliary trial balance. Taxes calculated on profits up to the balance sheet date are recorded in liabilities or assets, as applicable.

Below we present the reconciliations of the tax expense and the amounts is calculated by applying the statutory tax rate of 34% (income tax of 25% and social contribution tax of 9%) in the table below for the year ended December 31, 2022, 2021 and 2020.

&nbsp;&nbsp;&nbsp;&nbsp;(1) On July 8, 2020, the Company filed Writ of Mandamus No. 5012373-88.2020.4.03.6100 providing protection in recognizing challenges of its claims of illegality and unconstitutionality of the requirement to pay Corporate Income Tax ("IRPJ") and Social Contribution on Net Income ("CSLL") on interest income accruals at the SELIC rate arising from improperly collected taxes.

On September 24, 2021, the plenary of the Federal Supreme Court ("STF") judged, under the virtual system, the Extraordinary Appeal No. 1.063.187/SC, under general repercussion topic 962, which deals with IRPJ and CSLL on SELIC interest income on overpayments, similar to the Writ of Mandamus above. This judgment accepted, by unanimous vote, agreed to the claims of unconstitutionality for levying IRPJ and CSLL on tax overpayment. On September 30, 2021, the Judgment Minutes were published and, on December 16, 2021, the full decision was published.

[**Table of Contents**](#TOC)

Considering the effects of the general repercussion, the Company reprocess previous years' calculations and its tax losses increased. The company determined it will be able to utilize those additional tax losses based on future projections for profitability/profitability of the business. As a result of these assessments, in 2021 the Company recognized the amount of R$1,407,523, of which R$1,405,565 in deferred income tax and social contribution assets and R$1,958 in recoverable income tax and social contribution assets with a corresponding credit in the income tax and social contribution result. For 2022, as a result of the final and unappealable decision favorable to the claim, certified in the records on August 27, 2022, the Company has already been excluding the SELIC update on tax undue debts based on IRPJ and CSLL.

**g) Uncertainties about Income Tax Treatments**

The Company and its subsidiaries are defending several assessments filed by the Brazilian Federal Tax Authority ("RFB") for allegedly incorrect deductions of expenses, mainly related to the amortization of goodwill, at various administrative and judicial levels, in the amount of R$29,882,262 to December 31, 2022 (R$18,176,115 to December 31, 2021). The amount as of December 31, 2022, includes R$10,744,063, referring to a new assessment notice against the Company for the collection of IRPJ and CSLL related to the amortization of goodwill, drawn up by the RFB on January 31, 2023. Management, supported by the position of its legal advisors, believes that a large part of these deductions will likely be accepted in decisions of higher courts of last resort (acceptance probability greater than 50%).

When the Company and its subsidiaries believes that the probability of acceptance by the tax authority is less than 50%, a non-current tax and social contribution liability is recognized. The amount recognized was R$104,438 on December 31, 2022 (R$97,668 on December 13, 2021). These claims involve compensation for overpayment of income tax and social contribution not approved by the RFB.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Includes ICMS credits from the acquisition of property and equipment (available to offset in 48 months); requests for refund of ICMS paid on invoices that were subsequently cancelled; for the rendering of services; tax substitution; and tax rate difference; among others. Non-current consolidated amounts include credits arising from the acquisition of property and equipment of R $626,636 and R $578,290 on December 31, 2022 and 2021, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;(2) On May 13, 2021, the STF rendered a favorable decision for Leading Case RE 574706 in relation to the recognition of the right to exclude ICMS from the calculation basis of contributions to PIS and COFINS. As a result of this decision, the Company recognized in 2021 a credit in the amount of R $2,269,391 referring to two lawsuits that later became final on June 25, 2021 and on May 27, 2022. These processes have already been authorized by the RFB and the Company is already offsetting them (Notes 27 and 28).

Additionally, the Company has another legal suit that became final in 2018 for which it previously recognized the credit for the period from July 2002 to July 2014. The remaining portion of this process, relating to the period from April 1998 to June 2002, was not recognized at that time, as the Company considered it to be a contingent asset and, therefore, did not meet the parameters for accounting recognition. In August 2022, based on the evolution of more recent decisions handed down by the STF on a similar Leading Case, management, supported by its legal advisors, concluded that estimated recoverability had reached the status for recognition and therefore the remaining portion of the credit was recognized of R$1,145,658, in 2022. Also in 2022, after approval of the credit with the RFB, the Company started offsetting said credit.

[**Table of Contents**](#TOC)

At December 31, 2022, the balance available for offset is recorded in current assets totaling R$786,857 (R$1,579,117 as of December 31, 2021).

&nbsp;&nbsp;&nbsp;&nbsp;(3) Withholding income tax ("IRRF") credits on short-term investments, interest on equity and others, which are used as deduction in operations for the period and social contribution tax withheld at source on services provided to public agencies.

**12) INVESTMENTS**

**a) Accounting policy**

The Company and its subsidiaries hold investments in subsidiaries and jointly controlled companies, in addition to business combinations.

a.1) Subsidiary

The consolidation of a subsidiary begins when the Company obtains control over the subsidiary and ends when the Company ceases to exercise said control. Assets, liabilities and results of a subsidiary

acquired or sold during the year are included in the consolidated financial statements from the date on which the Company obtains control until the date on which the Company ceases to exercise control over the subsidiary.

Specifically, the Company controls an investee if, and only if, it has: (i) power over the investee (that is, existing rights that guarantee it the current ability to direct the relevant activities of the investee); (ii) exposure or right to variable returns arising from its involvement with the investee; and (iii) the ability to use its power over the investee to affect the value of its returns.

There is usually a presumption that a majority of voting rights results in control. To support this presumption and when the Company has less than a majority of the voting rights of an investee, the Company considers all relevant facts and circumstances when assessing whether it has power over an investee, including: (i) the contractual agreement between the investor and other holders of voting rights; (ii) rights arising from other contractual agreements; and (iii) the Company's voting rights and potential voting rights. The Company assesses whether it exercises control over an investee if facts and circumstances indicate that there are changes in one or more of the three aforementioned control elements.

a.2) Joint control

Joint control is the contractually agreed sharing of a control, only existing when decisions about relevant activities call for unanimous agreement by the parties sharing control.

[**Table of Contents**](#TOC)

Foreign exchange variations in Aliança's equity (jointly controlled entity) are recognized in the Company's equity in other comprehensive income ("Effects on conversion of investments abroad", Note 24.e).

a.3) Subsidiary and joint control

Based on the equity method, investments are recorded in balance sheets at cost plus changes after the acquisition of the equity interest. The statement of income reflects the portion of the results of operations of the investees.

When changes are directly recognized in the investees' equity, the Company will recognize its portion in variations occurred, and record these variations in the statements of changes in equity and in the statements of comprehensive income, where applicable.

The financial statements of investees are prepared for the same reporting period of the Company. Whenever necessary, adjustments are made so that the accounting policies are in accordance with those adopted by the Company.

After the equity method is applied, the Company determines whether there is any need to recognize additional impairment of its investment in investees. At each closing date, the Company determines whether there is objective evidence of impairment of investment in the affiliate. If so, the Company calculates the recoverable amount as the difference between the recoverable value of the investees and their carrying amount and recognizes the amount in the statement of incomes.

When there is loss of significant influence over the investees, the Company evaluates and recognizes the investment, at that moment, at fair value. Any difference between the investees' carrying amount by the time it loses significant influence and the fair value of the remaining investment and revenue from sale is recognized in the statement of incomes.

a.4) Business combination

Pursuant to IFRS 3 (R) - Business Combinations, business acquisitions are accounted for using the acquisition method. The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the fair values of assets acquired and liabilities assumed on the acquisition date from the acquiree's former controlling shareholders and any interests issued in exchange for control of the acquiree.

In the parent company, the difference between the amount paid and the equity value of the acquired entities is recognized in investments. For the consolidated information, the amounts of fair values and goodwill are allocated according to their nature.

**b) Information on investees**

Below, we present summarized information on the jointly controlled subsidiaries of the Company:

**13) PROPERTY, PLANT AND EQUIPMENT**

**a) Accounting policy**

It is measured at acquisition and/or construction cost, net of accumulated depreciation and/or accumulated impairment losses, if any. Such cost includes the borrowing costs for long-term construction projects if the recognition criteria are met and is stated net of ICMS (State VAT) credits (Note 9), which were recorded as recoverable taxes. The Company does not have loans that meet the criteria for recognition of cost capitalization.

Asset costs are capitalized until the asset becomes operational. Costs incurred after the asset becomes operational and that do not improve the functionality or extend the useful life of the asset are immediately recognized on an accrual basis. When significant parts of fixed assets are required to be replaced at intervals, the Company recognizes such parts as individual assets with specific useful lives and depreciation. Likewise, expenses that represent asset improvement (expanded installed capacity or useful life) are capitalized. All the other repair and maintenance costs are recognized in the statement of income as incurred.

The present value of the expected cost for the decommissioning of property, plant and equipment items (towers and equipment on leased property) is capitalized at the cost of the respective asset matched against the provision for dismantling obligations (Note 20) and depreciated over the useful lives of the related assets, which do not exceed the lease term.

Depreciation is calculated by the straight-line method over the useful lives of assets at rates that take into account the estimated useful lives of assets based on technical analyses.

The assets' residual values, useful lives and methods of depreciation are reviewed on a yearly basis, adjusted prospectively, if appropriate.

[**Table of Contents**](#TOC)

Property, plant and equipment items are written off when sold or when no future economic benefit is expected from their use or sale. Any gains or losses arising from write-off (measured as the difference between the net disposal proceeds and the carrying amount) are recognized in the statement of income in the year in which the asset is written off.

Leases

The Company applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low value assets, as permitted by IFRS 16. They recognize lease liabilities to make lease payments and assets rights of use representing the right of use of the underlying assets.

The Company recognizes the right-of-use assets on the lease start date (that is, on the date the asset is available for use). The rights of use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any new remeasurement of lease liabilities.

The Company acts as a lessee in a significant number of lease agreements on different assets, such as structures (towers and rooftops) and the respective land where they are located; sites built in the Built to Suit ("BTS") modality for installing antennas and other equipment and means of transmission; computer equipment; offices, shops and commercial properties.

**b) Critical estimates and judgments**

The accounting treatment of investment in fixed assets includes estimating the useful life period for depreciation purposes, particularly for assets acquired in business combinations.

Useful life determination requires estimates regarding the expected technological developments and alternative uses of assets. The hypotheses related to the technological aspect and its future development imply a significant level of analysis, considering the difficulties in forecasting the time and nature of future technological changes.

Information on the recoverability of fixed assets is presented in Note 15.a.

**c) Description, Breakdown and changes**

We present a brief description of the main items that make up fixed assets.

● Switching and transmission media equipment: Includes switching and control centers, gateway, platforms, base radio station, microcells, minicells, repeaters, antennas, radios, access networks, concentrators, cables, TV equipment and other switching and transmission media equipment.

● Terminal equipment: Includes CPCT, public telephones and other terminal equipment.

● Lending equipment: Includes cellphones and modems in the lending modality.

● Infrastructure: This includes buildings, elevators, central air conditioning equipment, towers, posts, containers, energy equipment, land piping, support and protectors, leasehold improvements, etc.

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;(1) Additions from property, plant and equipment mainly refers to: (i) in 2022: expansion of the fiber network, maintenance and expansion of the 4G mobile network and launch of the 5G mobile network in Brazilian capitals, in addition to investments for the integration of hi mobile; (ii) in 2021: reinforcement of the mobile network, expansion of the fiber network and connected homes, increasing the availability of services in view of the growing demand for quality connection.

&nbsp;&nbsp;&nbsp;&nbsp;(2) In infrastructure, includes the amounts of R $52,092 and R $245,237 in 2022 and 2021, respectively, referring to the cancellation of lease agreements.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Refers to the balance of assets that were used for the Company's corporate structure in FiBrasil (Note 2.d).

**d) Depreciation rates**

In the years ended December 31, 2022 and 2021, the Company carried out, with the help of a specialized company, valuations of the useful lives applied to its property, plant and equipment through the direct comparative method of market data.

For the year ended December 31, 2022, the works indicated the need for changes in the useful life and annual depreciation rates of some items of the asset classes. These changes in the accounting estimate reduced the depreciation expense by R$295,464 in 2022. For the year ended December 31, 2021, the works did not indicate the need for changes in the useful life and annual depreciation rates.

Below, we present a table of the annual depreciation rates for the years ended December 31, 2022 and 2021, except for lease assets, which are presented in note 13.e.

**g) Concession Balance**

The Fixed Switched Telephone Service concession model, adopted in 1998 with the signing of contracts celebrated thanks to the privatization of the telecommunications sector, generated a veritable revolution in the provision of telecommunications services in Brazil. Over more than 20 years, concessionaires promoted the expansion and universalization of the fixed telephone service, which, before privatization, was expensive, elitist and left consumers in a long queue, lasting months or years. During this period, the concession contracts suffered shocks as a result of several events that occurred throughout their term, which have repercussions to the present day on the originally contracted financial equation.

As the end of the term of the concession contracts approaches, a consensus is being sought with the regulatory body to assure a fair the economic-financial equilibrium.

However, management's efforts have largely been frustrated and discussions through administrative channels have been exhausted without consensus having been reached. Hence, on July 1, 2021, the Company signed an arbitration agreement with ANATEL. The Company submitted to the International Chamber of Commerce, on July 10, 2021, a request to initiate an arbitration against ANATEL, as provided for in the concession agreement and pursuant to Law 9,307/1996, as well as the General Telecommunications Law.

On March 21, 2022, the Company presented its opening arguments in the arbitration proceeding requiring, among other issues, the recognition of events that occurred during the concession agreement that need to be rebalanced in the Company's favor to preserve the sustainability of the agreement, as well as compensation for the period in which the contract terms were untenable.

After the Company's initial allegations, in June 2022 ANATEL presented its defense. On August 19, 2022, the Company filed a reply to ANATEL's defense. On October 18, 2022, the rejoinder was presented by ANATEL. On November 17, 2022, the parties specified the evidence and on December 8, the parties' hearing was held with the arbitral tribunal for the presentation of the case.

Arbitration is generally an agile and technically satisfactory option for resolving complex conflicts. The expectation is that disputes involving the concession can be addressed within a technical basis, enabling the current fixed telephone service concessions to be drawn to a close in a fair manner. Currently, it is not practicable to predict the outcome of this arbitration process.

**h) Adaptation of the Model**

On October 4, 2019, Law 13.879/2019 (enacted from PLC 79/2016) was sanctioned, which introduced changes in the telecommunication's regulatory framework, by allowing fixed telephony concessionaires to migrate from a concession regime to an authorization regime with lower regulatory charges, including those associated with the continuity and universalization of the STFC in the concession area, as well as any restrictions on the goods associated with its provision.

In accordance with said Law, ANATEL presented on July 5, 2022 a methodology with an estimate of the economic value associated with the adaptation of the concession instrument for authorization, to be validated by the Federal Court of Auditors ("TCU"), which after the vote of the reporting minister on the legality of the methodology presented by ANATEL, received a request for views from another minister, and should return to the court's agenda in March 2023. After the TCU's final decision on the applied methodology, ANATEL will indicate the final value for adapting the concession instrument for authorization. This amount, after being confirmed and accepted by the Company, will be converted into investment projects not yet defined by ANATEL.

**i) Reversible assets**

The concession contract for the Company's Switched Fixed Telephone Service identifies the assets essential to the provision of such service in the concession area. On April 12, 2021, Resolution 744 was published in the official gazette ("DOU"), approved by the Ministry of Telecommunications and by the Board of Directors of ANATEL on April 4, 2021, which addresses the Regulation of Continuity of Provision of Switched Fixed Telephone Service Intended for Use of the General Public under the Public Regime ("RCON").

[**Table of Contents**](#TOC)

The Resolution, which became effective on May 3, 2021, addresses how the continuity of STFC services under the concession regime are treated once the Company's STs STFC concession contract terminates. The assets identified as being essential to the provision of multiple services, among which the STFC under the public system, will be included in a contract for the assignment of their rights of use, to be agreed under fair and reasonable economic terms and conditions, transferring them from the Company to the new Concessionaire or the Federal Government, should they wish to make use of such assets to maintain the continuity of STFC provision under the public regime.

The assets which in addition to being deemed essential are effectively and exclusively used to ensure the continuity and timely provision of STFC under the public regime, will be revert to the Public Authority, according to the terms of the RCON, if such service continues to be provided, either by the Federal authority, or by a new Concessionaire, under a public agreement. Hence, the assets for the exclusive use of the STFC and, therefore, subject to the 'reversal regime' provided for in the regulation, constitute a residual and decreasing asset of the Company.

Accordingly, the Concessionaire's assets, at the end of the concession contract on December 31, 2025, will not be returned to the Federal Government. The shared assets and those used exclusively for the STFC will fall within the scope of specific contracts already provided for in the operational manual of the Continuity Regulation, approved by Decision No. 269/2021/COUN/SCO, which complements provisions of the Continuity Regulation.

Although Resolution 744 requires a list of Reversible Assets ("RBR") to be submitted to ANATEL, such obligation, upon approval under the contractual model described above, is merely informative by nature, in order to maintain transparency of the assets used by the Concessionaire in the provision of STFC under the public regime.

However, it is important to point out that, within the scope of the administrative proceeding TC nº. 003.342/2022-0, pending at the TCU, a technical report was issued mentioning the new understanding that the RCON should be revised. This understanding will still be subject to appreciation by the Court.

#### 14) INTANGIBLE ASSETS
**a) Accounting policy**

Intangible assets acquired separately are measured at acquisition / formation cost upon their initial recognition. The cost of an intangible asset are capitalized until the asset becomes operational. The cost of an intangible asset acquired in a business combination is its fair value at the acquisition date.

After initial recognition, intangible assets are stated at acquisition and/or buildup cost, net of amortization and accumulated provision for impairment, where applicable. Intangible assets generated internally, excluding capitalized development costs, are not capitalized, and the expense is reflected in the statement of income for the year in which it is incurred.

The useful lives of intangible assets are considered finite or indefinite.

● Intangible assets with finite useful lives **  are amortized over their economic useful lives under the straight-line method and are tested for impairment whenever there is any indication of impairment loss. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed on an annual basis.

Changes in the estimated useful life or the expected pattern of consumption of future economic benefits embodied in an asset are accounted for by changing the amortization period or method, as appropriate, and treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in the statement of income in the cost/expense category consistent with the function of the intangible assets.

● Intangible assets with indefinite useful lives are not amortized, but are tested for impairment annually, either individually or at the CGU level. The assessment of indefinite life is reviewed annually to determine whether the indefinite life continues to be justifiable. Otherwise, changes in useful life – from indefinite to finite - are carried out prospectively. Goodwill generated upon investment acquisition is treated as an intangible asset with indefinite useful lives.

[**Table of Contents**](#TOC)

When goodwill has been allocated to a CGU and part of the operation within that CGU is disposed that, the goodwill associated with that operation is included in the carrying amount of the operation when determining the gain or loss on disposal. Goodwill disposed in these circumstances is allocated based on the relative fair values of the disposed operation and the portion of the CGU retained.

Gains and losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and recognized in the statement of income on disposal.

**b) Critical estimates and judgments**

The accounting treatment of the investment in intangible assets includes making estimates to determine the useful life for amortization purposes, particularly for assets acquired in business combinations.

The determination of the useful lives requires estimates in relation to the expected technological evolution and the alternative use of the assets. Hypotheses related to the technological aspect and its future development imply a significant degree of analysis, since the timing and nature of future technological changes are difficult to predict.

Information on the recoverability of fixed assets is presented in note 15.a.

**c) Breakdown and changes** 

A brief description of the key intangible asset items with finite useful lives, is as follows:

● Software: This includes licenses for software used in the Company's operating, commercial and administrative activities.

● Customer portfolio and trademarks: This includes intangible assets acquired through business combination.

● Licenses: These include concession and authorization licenses, acquired from ANATEL for provision of telecommunication services. These also include licenses from business combinations.

**d) Licenses / Authorizations**

*Extension of authorizations for the 850 MHz, 900 MHz and 1800 MHz bands*

With respect to the extension of authorizations for the 850 MHz bands, ANATEL through Judgment No. 510 of September 30, 2020, determined that (i) the Superintendence of Granting and Resources for Provision ("SOR") addresses the requests for extension of authorizations for the use of radio frequencies in force in sub-bands A and B, proposing primary grants until November 29, 2028, if legal and regulatory requirements are met; and that (ii) the extension value should be discounted to net present value, to reflect the economic value (market value) of the bands.

Having complied with the SOR procedures, the ANATEL Board through Judgment No. 618, of November 26, 2020, extended the term of the authorization for the right to use radio frequencies, for bands 869.0 to 880.0 MHz, 824.0 to 835.0 MHz, 890.0 to 891.5 MHz and 845.0 to 846.5 MHz, associated with Authorization Term No. 001/2006 / PVCP / SPV- ANATEL through to November 29, 2028. No exclusivity was granted, being on a primary basis and restricted to the provision area serving the State of Rio de Janeiro, pursuant to Act No. 7,281, of November 26, 2020.

The extension granted for a period less than the maximum limit provided for by Law (20 years), in the opinion of ANATEL, was to promote a reorganization and readaptation of the channel. Alternative calculation methods (biannual charges and Resolution No. 695/2018, as approved in the Public Price Regulation for the Right to Use Radio Frequencies ("PPDUR")) is justified on the grounds that the current regulatory instruments are not expected to involve a second extension. ANATEL further determined that 10% should be effectively paid in cash and the remaining 90% settled in the form of investments.

Similarly, ANATEL extended the period of validity of authorizations for the right to use radio frequencies relating to the 869.0 to 880.0 MHz, 824.0 to 835.0 MHz, 890.0 to 891.5 MHz and 845.0 MHz bands at 846.5 MHz in the area of provision equivalent to the Federal District, associated with the Authorization Term No. 003/2006/PVCP/SPV-ANATEL. Extension authorizations were granted for the State of Rio de Janeiro, under term and payment conditions, as stated in Act No. 5,473, of July 21, 2021.

The Company and other providers appealed certain conditions for the renewal of the license, including the evaluation criteria and certain obligations. ANATEL dismissed the appeals and submitted the process to the Federal Audit Court for ratification of the calculations referring to the amount due for the extension.

In September 2022, the Federal Court of Auditors ("TCU") defined a standard procedure for authorizations, other than the extensions of the awards for 850 MHz to 2028, acquired prior to the publication of Law No 13.879/2019 to regulate the conduct of the bidding process. This decision affected the expectation for tenders to 2028 (to 850 MHz). The Company appealed the decision and the case continues under review of the TCU.

As a condition for renewing the 850 MHz sub-band license, a judicial writ of mandamus is being filed, though the security was denied in the first instance, and the appeal is pending judgment at the Federal Regional Court of the First Region.

The terms of authorization for the use of the 900 MHz and 1800 MHz sub-bands are expected to expire by 2023. With the exception of authorization terms No. 002/2005/PVCP/SPV-ANATEL and No. 017/2005/ PVCP/SPV-ANATEL, associated, respectively, to the 900 MHz and 1800 MHz sub-bands in sector 3 of the PGO (region in the state of MG), the use authorizations for these sub-bands had not previously been extended. ANATEL has the discretion to proceed with the extension under the terms of the authorization allowing for an extension for 15 years in return for payment equivalent to 2% of the net operating revenue of the SMP, paid biannually.

However, ANATEL recently selected another operator (TIM) to which it granted an authorization extension for the 900 MHz and 1800 MHz bands up to 2032. Should ANATEL decide to treat the Company's authorizations in a similar manner to the 2032 sectorial relocation of the associated pipelines in the sub-bands, as applied for the 850 MHz sub-bands, this will shorten by six year the term of the original authorizations which have yet to be extended (15 years terms, expiring in 2038). As to the 900 MHz and 1800 MHz authorizations in sector 3 (Minas Gerais), which have already been extended, this decision would represent an extension of nine years for these authorization terms (30 years, 15 years of which original term and 15 years extension).

[**Table of Contents**](#TOC)

*5G License Auctions*

On December 3, 2021, ANATEL signed the Terms of Authorization for the Use of Blocks of Radiofrequencies Associated with SMP No. 86, 87 and 88/2021 ("Terms"), in the radio frequency sub-bands of 2,300 MHz to 2,390 MHz, 3,300 MHz to 3,700 MHz and 24.3 GHz to 27.5 GHz, from auctions for the implementation of fifth generation technology ("5G"), held by ANATEL on November 4 and 5, 2021, which were awarded to the Company as the successful bidder.

These authorizations are valid for 20 years, starting on December 8, 2021, date of publication of the present extracts of the Terms in the Diário Oficial da União ("DOU"), associated with the authorizations for the provision of SMP, issued by Terms no. 78/2012/PVCP/SPV -ANATEL, n.o. 05/2010/PVCP/SPV-ANATEL and N.o. 06/2010/PVCP/SPV-ANATEL, renewable, successively, pursuant to Law 9472/1997.

In accordance with the procedures established within the scope of the Invitation to Bid, in addition to the amounts of radiofrequency licenses to be paid to ANATEL, the winning operators constituted and are making joint contributions of resources in the 3.5 GHz Band Management Entity ("EAF") and the School Connectivity Administrator ("EACE"). The installments that fell to the Company totaled 4,459,442, of which: (i) R$928,738 from radio frequency licenses; (ii) R$2,104,456 of contributions to EAF and; (iii) R$1,426,248 of contributions to EACE.

As a requirement for obtaining these authorizations, the Company, as well as the other successful telecommunication service bidder providers, assumed a series of commitments. For the 2.3 GHz and 3.5 GHz spectrum band obligations for coverage commitments and fiber optic backbone network deployment in locations with little or no connectivity infrastructure. In addition, the successful bidders for the 3.5 GHz band must fund all activities related to the migration of satellite TV services from the C band to the Ku band (notably the migration of TVROs and mitigation of interference in the FSS systems), for the construction of six high-capacity info-ways by laying sub fluvial cables for the Integrated and Sustainable Amazon Program ("PAIS") and the implementation of private (fixed and mobile) communication networks reserved for the Federal Public Administration. EAF will be responsible for the execution of these activities. The successful bidders for the 26 GHz spectrum bands will be required to fund EACE's activities for broadband connectivity projects for public schools to be selected across the country.

The 26GHz frequency will allow the Company to increase its network capacity in areas denser urban areas, and will be used, in conjunction with the 3,500MHz and 2300MHz frequencies, on the first day of the auction, to offer spectral capacity to implement the 5G technology nationwide.

With the acquisition of the frequencies described above, the Company guarantees the spectrum necessary for the provision of the 5G service in the medium and long term, reinforcing the leadership in the mobile service to the offer its customers the most advanced solutions in terms of speed, quality and stability, thus meeting the growing demand for connectivity and accelerating its digital ecosystem.

The Company considers that this new technology reinforces its operations in the market in which it operates, not identifying any signs of impairment of assets, as well as the need to change the useful lives of other technologies currently used.

*Authorizations in the 450 MHz band*

As part of the 2012 auctions, ANATEL allocated a 450 MHz frequency lot associated with the 2.5 GHz band, designed to meet the demand for voice and data services in remote rural areas. Following the acquisition of 450 MHz concessions, the Company assumed an obligation to provide infrastructure in rural areas in the states of Alagoas, Ceará, Minas Gerais, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, Sergipe and the interior of São Paulo, covering 2,556 municipalities.

In addition, on December 8, 2022, ANATEL revoked the Company's 450 MHz spectrum authorization (451-458 MHz and 461-468 MHz) covering the states of Alagoas, Ceará, Minas Gerais, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, Sergipe and part of São Paulo. The decision was motivated by the fact that the Company could not provide evidence of service activation in the 450 MHz band due to the unavailability of the 450 MHz device ecosystem and the waiver clause contained in the public notice, interpreted by ANATEL in the sense that the waiver would work automatically in the event of non-activation of the frequency within the contractual term. Previously, in September 2022, ANATEL revoked authorizations held by other providers.

**15) IMPAIRMENT OF NON-FINANCIAL ASSETS**

**a) Accounting policy**

The Company annually reviews the net carrying amount of assets in order to evaluate events or changes in economic, operating or technological circumstances that may indicate impairment losses. When such evidence is found, and net carrying amount exceeds recoverable amount, a provision for impairment is recorded so as to adjust the net carrying amount to the recoverable amount. The recoverable amount of an asset or a Cash-Generating Unit ("CGU") is defined as the higher of value in use and net sales value.

Considering the convergence of product and service offerings, in addition, the Company's main operating asset is a single, broadly integrated network, which is used to provide all telecommunications services to its customers, the Company defines your business as a single CGU.

Upon estimation of the value in use of an asset or cash-generating unit, estimated future cash flows are discounted at present value using a discount rate Weighted Average Cost of Capital "WACC" which reflects the weighted rate between (i) the cost of capital (including specific risks) based on the Capital Asset Pricing Model; and (ii) the debt these components being applicable to the asset or CGU before taxes.

The net fair value of sales is determined, whenever possible, based on recent market transactions between knowledgeable and interested parties with similar assets. In the absence of observable transactions in this regard, an appropriate valuation methodology is used. The calculations provided in this model are corroborated by available fair value indicators, such as prices quoted for listed entities, among other available indicators.

For assets excluding goodwill, an assessment is made at each reporting date as to whether there is any indication that previously recognized impairment losses may no longer exist or may have decreased. If the indication exists, the Company estimates the recoverable amount of the asset or the CGU.

[**Table of Contents**](#TOC)

A previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine an asset's or CGU recoverable amount since the last impairment loss was recognized. Any reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount or exceeds the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in the statement of income.

The following assets have specific characteristics for impairment testing:

● Goodwill: Goodwill is tested for impairment annually at the reporting date or earlier when circumstances indicate that the carrying amount may be impaired. Where the recoverable amount is lower than the carrying amount, an impairment loss is recognized. Impairment losses relating to goodwill cannot be reversed in future periods.

● Intangible assets: Intangible assets with indefinite useful lives are tested for impairment annually at the reporting date either individually or at the CGU level, as appropriate, and when circumstances indicate that the carrying amount may be impaired.

● Determination of value in use of property, plant and equipment, goodwill and intangibles: The key assumptions used to estimate value in use through the discounted cash flow methodology are: (i) revenues (projected considering the growth in customer base, growth in market revenue against GDP and the Company's share of this market); (ii) variable costs and expenses (projected in accordance with the dynamics of the customer base, and fixed costs are projected in line with the historical performance of the Company, as well as with revenue growth); and (iii) capital investments (estimated considering the technological infrastructure necessary to enable the provision of services).

**b) Critical estimates and judgments**

An impairment loss exists when the carrying amount of an asset or UGC exceeds its recoverable amount, which is the greater of fair value net of selling expenses and value in use. The calculation of fair value net of selling expenses is based on information available from transactions for the sale of similar assets or market prices less selling expenses. The value in use calculation is based on the discounted cash flow model. Cash flows derive from the budget for the next five years and do not include reorganization activities to which the Company and its subsidiaries have not yet committed or significant future investments that will improve the asset base of the CGU, which is the object of testing. The recoverable amount is sensitive to the discount rate used in the discounted cash flow method, as well as expected future cash receipts and the growth rate used for extrapolation purposes.

**c) Key assumptions used in the calculation of value in use:**

The value in use is mainly impacted by the following assumptions:

● Revenue growth: based on the observation of the historical behavior of each revenue line, as well as trends based on market analysis. The projected revenue differs between product lines and services with a tendency of growth in broadband services, IPTV and IT compared to voice services (fixed). Mobile revenues follow the market trend, including a new mix between prepaid, post and control, migrations from prepaid to post and control, price convergence and growth in data and M2M.

● Discount rate: represents the assessment of risks in the current market. The calculation of the discount rate is based on the Company's specific circumstances and being calculated based on the WACC. The WACC takes into account both debt and equity. The cost of equity is derived from the expected return on investment by Company investors. The cost of debt is based on loans with interest income that the Company is obliged to honor. The specific risk business is incorporated by applying individual notably Beta factors.

● Perpetuity growth rate reflects the Company's condition to generate cash flow in an eternal manner. The percentage considered mainly takes into account investments over the projected period and reproduces the Company's condition in perpetuity.

[**Table of Contents**](#TOC)

**d) Sensitivity to changes in assumptions:**

The Company carries out a sensitivity analysis of the impairment test by considering reasonable changes in the main assumptions used in such test.

The following table shows the increases in/decreases in the percentage points (p.p) which were assumed for the years ended December 31, 2022 and 2021:

---

| | | |
|:---|:---|:---|
| <br>**Changes in key assumptions** |  | **In percentage**<br>**points (p.p)** |
| **Financial variables** |  |  |
| &nbsp;&nbsp;Discount rate |  | +/- 0.5 |
| &nbsp;&nbsp;Perpetuity growth rates |  | +/- 1.0 |
| **Operating variables** |  |  |
| &nbsp;&nbsp;Revenues Margin |  | +/- 1.5 |

---

The sensitivity analysis performed at year-end 2022 and 2021 indicates that there are no significant risks arising from possible changes in the financial and operating variables, considered individually. In other words, the Company considers that within the above limits, no losses would be recognized.

**e) Goodwill impairment testing**

Annually, the Company assesses recoverability of goodwill carrying amounts based on the value in use.

The process for determination of the value in use involves the use of assumptions, judgments and estimates on cash flows, such as revenue, cost and expense growth rates, estimated future investments and working capital and discount rates. The assumptions about cash flow increase projections are based on management's estimates, market studies and macroeconomic projections. Future cash flows are discounted at the WACC rate.

Consistent with the economic analysis techniques, the assessment of value in use is made for a period of five years, and thereafter, considering the perpetuity of the assumptions based on the capacity of business continuity for an indefinite time. Management considered that the period of five years is adequate, based on its past experience in preparing cash flow projections.

The nominal growth rate used to extrapolate projections beyond the five years period was 4.5% p.a. in 2022 and 2021.

The estimated future cash flows were discounted at a discount rate of 12.60% and 12.00%, which before taxes are 14.18% and 13.64% in 2022 and 2021, respectively, also in nominal values.

The inflation rate for the period analyzed in the projected cash flows was 3.21% p.a. and 3.15% p.a. in 2022 and 2021, respectively.

Key assumptions were based on the Company's historical performance and reasonable macroeconomic assumptions grounded on financial market projections, documented and approved by the Company's management.

Based on annual impairment testing of the Company's assets, prepared using projections considering the financial statements on December 31, 2022 and 2021, growth projections and operating results for the year ended December 31, 2022 and 2021, no impairment losses or evidence of losses were identified, since the value was in use is higher than the net carrying amount as at the assessment date.

#### 19) DIVIDENDS AND INTEREST ON EQUITY
**a) Accounting policy**

a.1) Dividends

Minimum mandatory dividends are stated in the balance sheet as legal obligations (provision in current liabilities). Dividends in excess of such minimum amount, not yet approved in the Shareholders' Meeting, are recorded in equity as proposed additional dividends. After approval at the Shareholders' Meeting, the dividends in excess of the mandatory minimum are transferred to current liabilities and classified as legal obligations.

a.2) Interest on equity

Brazilian legislation allows companies to pay interest on equity, which is similar to payment of dividends; however, this is deductible for income tax calculation purposes. In order to comply with Brazilian tax legislation, the Company and its subsidiaries provision, in its accounting records, the amount due to match against the financial expenses account in the statement of income for the year. For the presentation of these financial statements, that expense is reversed against a direct charge to equity, resulting in the same accounting treatment adopted for dividends. The distribution of interest on equity to shareholders is subject to withholding income tax at a 15% rate.

a.3) Unclaimed dividends and interest on equity

The rights to receive unclaimed interest on equity and dividends prescribe after three years from the initial date available for payment. When dividends and interest on equity expire, these amounts are reversed to retained earnings.

#### 20) PROVISION AND CONTINGENCIES
**a) Accounting policy**

Provision is recognized when the Company has a present obligation (legal or constructive) as a result of a past event, when it is probable that economic benefits are required to settle the obligation and a reliable estimate of the value of the obligation can be made. Provision is restated at the balance sheet date considering the likely amount of loss and the nature of each provision.

Provision amounts for contingencies are presented at their gross amount, less the corresponding judicial deposits, and are classified as provision for labor, tax,civil, and regulatory contingencies.

Judicial deposits are classified as assets given that the conditions required for their net presentation with provision do not exist.

Provision for legal claims

The Company and its subsidiaries are parts to administrative; labor, tax, civil and regulatory claims, and accounting provision amounts have been recorded in respect of claims whose likelihood of loss was classified as probable. The assessment of the likelihood of loss includes an analysis of available evidence, the hierarchy of laws, available case law, the latest court decisions law and their relevance in the legal system, as well as the opinion of outside legal counsel. Provision is reviewed and adjusted considering changes in existing circumstances, such as the applicable statute of limitations, tax audit conclusions, or additional exposures identified based on new matters or court decisions.

Contingent liabilities recognized in a business combination

Refers to the amounts of contingent liabilities arising from the PPA generated in the acquisition of control of VivoPart. in 2011, GVTPart. in 2015 and from Garliava and Vita IT in 2022, related to civil, labor and tax lawsuits at their fair value in the business combination.

Amounts to be refunded to customers (Supplementary Law No. 194/2022)

On July 23, 2022, Complementary Law No. 194, of July 23, 2022, was enacted, which deals with the incidence of taxes on various sectors considered by the respective Law as essential and indispensable goods and services, leading to a reduction in the tax rate ICMS on communications services and the respective refund of these amounts to customers. These amounts to be refunded to customers were booked against discounts granted (note 25).

[**Table of Contents**](#TOC)

Provision for decommissioning of assets

Refers to costs to be incurred due to returning sites to owners (locations intended for tower and equipment installation on leased property) in the same condition as these were found at the time of execution of the initial lease agreement.

These costs are provisioned as the present value from amounts expected to settle the obligation using estimated cash flows and they are recognized as part of the cost of the corresponding asset. The cash flows are discounted at a current pre-tax rate that reflects the risks specific to decommissioning of assets. The financial effect of the discount is recorded as incurred and recognized in the statement of income as a finance cost. The estimated future costs of decommissioning are reviewed annually and adjusted as appropriate. Changes in the estimated future costs or in the discount rate applied are added to, or deducted from, the cost of the asset.

Provision for fines for canceling lease agreements

Refers to the provision for fines for canceling lease agreements arising from Garliava, resulting from the sale or shutdown of sites.

**b) Critical estimates and judgments**

The obligation arising from the provisions can be legal or constructive, derived from, among other factors, regulations, contracts, customary practices or public commitments that expose third parties to a valid expectation that the Company or its subsidiaries will assume certain responsibilities. The determination of the provision is based on the best estimate of the disbursement required to settle the corresponding obligation, considering the information available as at the closing date, including the opinion of independent experts, such as legal advisors.

**c) Information on provisions and contingencies**

Below, we present the tables with the composition and movement of provisions, whose unfavorable outcome is considered probable, in addition to contingent liabilities, provision for dismantling, amounts to be refunded to customers and provision for fines for cancellation of lease agreements.

c.3.2) Possible losses - civil contingencies

Management, under advice of legal counsel, believes that the risk of losses is possible for the following civil proceedings:

[**Table of Contents**](#TOC)

● Collective Action filed by SISTEL Participants' Association ("ASTEL") in the state of São Paulo, in which SISTEL associates in the state of São Paulo challenge the changes made in the PAMA and claim for the reestablishment of the prior "status quo". This proceeding is still in the appeal phase and awaits a decision on the Interlocutory Appeal filed by the Company against the decision on possible admission of the appeal to higher and supreme courts filed in connection with the Court of Appeals' decision, which partially changed the decision rendering the matter groundless. In parallel, the parties formulated an agreement, filed though pending court approval. The amount cannot be estimated, and the claims cannot be settled due to their unenforceability because it entails the return to the prior plan conditions.

● Public Civil Action proposed by the National Federation of Associations of Retirees, Pensioners and Participants in Pension Funds in the Telecommunications Sector ("FENAPAS"), in which ASTEL is an assessor against Sistel, the Company and other operators, to annul the spin-off of the PBS pension plan. The action is claiming, in summary, the "dismantling of the supplementary pension system of Fundação Sistel", which originated several specific PBS mirror plans, and corresponding allocations of resources from the technical surplus and tax contingency existing at the time of the spin-off. After upholding the lawsuit in the first degree and confirming the sentence at the appellate level, the Company filed an appeal for clarification. Concurrently, the National Superintendence of Complementary Social Security ("PREVIC") intervened in the process, which caused the case to be sent to the Federal Court. The process is awaiting receipt at the Federal Court. The Federal Court then summoned PREVIC to manifest itself in the records and, successively, to the parties and the FENAPAS. The case records were submitted for conclusion, where they await decision. On July 3, 2022, a decision was rendered acknowledging PREVIC's interest and subpoenaing the plaintiff, FENAPAS, to promote the inclusion of the co-defendant, under penalty of extinction of the act, which was provided on July 12, 2022. The Federal Government also requested its entry into the case, considering the admission of PREVIC as a necessary co-defendant. FENAPAS presented a transaction instrument signed by the parties. The agreement was ratified by the court, extinguishing the process. Awaiting certification of the final and unappealable decision and filing of the records.

● The Company and its subsidiaries are party to other civil claims, at several levels, related to service rendering rights. Such claims have been filed by individual consumers, civil associations representing consumer rights of consumers or by the Consumer Protection ("PROCON"), as well as by the Federal and State Public Prosecutor's Office. The Company is also party to other claims of several types related to the ordinary course of business.

● Intellectual Property: Lune Projetos Especiais Telecomunicação Comércio e Ind. Ltda. ("Lune"), a Brazilian company, filed lawsuits on November 20, 2001, against 23 wireless carriers claiming to own the patent for "Bina", a caller ID. The purpose of the lawsuit was to interrupt provision of such service by carriers and to seek indemnification equivalent to the amount paid by consumers for using the service.

An unfavorable decision was handed down determining that the Company should refrain from selling mobile phones with the Bina ID service, subject to a daily fine of R$10 in the event of non-compliance. Furthermore, according to that decision, the Company must pay indemnification for royalties, to be calculated on settlement. Motions for Clarification were proposed by all parties and Lune's motions for clarification were accepted since an injunctive relief in this stage of the proceedings was deemed applicable. A bill of review appeal was filed in view of the current decision which granted a stay of execution suspending the unfavorable decision until final judgment. A bill of review was filed in view of the sentence handed down on June 30, 2016, by the 4th Chamber of the Court of Justice of the Federal District, in order to annul the lower court sentence and remit the proceedings back to the lower court for a new examination. The expert investigation was carried out and the claim was dismissed. Appeals have been filed by the parties, pending judgment. Management is unable to reasonably estimate a liability with respect to this claim at this time.

● The Company, together with other operators that provide telecommunications services, is a defendant in discussions that contest the practice that operators adopt of imposing a limited period for the use of prepaid minutes. That is, the plaintiff alleges that the minutes of the prepaid package must not expire after the end of a specific period, and that they can be used at any time by the consumer. The request of the Federal Public Ministry was not accepted, and the processes are awaiting judgment of appeal by the Federal Regional Court ("TRF") of the 1st Region.

c.4.1) Regulatory provisions

Management, under advice of legal counsel, believes the likelihood of loss of the following regulatory proceedings is probable:

The Company is a party to administrative proceedings initiated mainly by ANATEL on the grounds of alleged non-compliance with obligations in the sectoral regulations, as well as in lawsuits that discuss, in the great majority, sanctions applied by ANATEL at the administrative level. The proceedings include the obligation to pay the onerous fee for the mobile service (the payment, due every two years, relating to the right of use of SMP), Company's obligations related to non-observance of the rights of consumers of telecommunications services, the achievement of ANATEL's quality indicators, and the achievement of targets contained in the spectrum auction notice for service coverage.

A dispute arose as to which revenues should be considered for the payment of amounts due for the renewal of radio frequencies in relation to the payment of SMP charges. The Company, together with its legal advisors, concluded that a probable loss is estimated of R$673 million on the payment of the SMP burden in relation to data revenue, due to the existence of unfavorable decisions at ANATEL in 2021 and in the courts with an unlikely prognosis of review, as the Company decided to begin collecting such amounts in favor of ANATEL, as of the 2022 collection.

c.4.2) Possible losses - regulatory contingencies

Management, under advice of legal counsel believes the likelihood of loss of the following regulatory proceedings is possible:

The Company is a party to administrative proceedings filed by ANATEL (other agents, including other operators, also have claims against the Company) alleging non-compliance with the obligations set forth in industry regulations, as well as legal claims which discuss the mostly sanctions applied by ANATEL at the administrative level.

Significant cases with possible risks of loss in the regulatory contingency portfolio include:

● Litigation regarding the revenues to be included in the calculation of the amount of encumbrance due to the extension of radio frequencies associated with the SMP and the STFC concession (except for SMP data revenues, as informed in item d.1, of this Note). In ANATEL's view, the calculation of the encumbrance should be based on 2% on the entire economic benefit arising from the provision of STFC/SMP service. In the Company's view, however, revenues that are not part of STFC/SMP service plans, such as interconnection, revenues earned in the 15th year of the licenses' validity, and others, should not be considered in the calculation of the burden. As a result of this divergence of understanding, the Company filed administrative and legal actions to challenge ANATEL's charges.

● In May 2018, the Company filed a lawsuit to annul the ANATEL final decision, of March of the same year, in the records of the Procedure for Determining Noncompliance with Obligations ("PADO") for alleged violations of the fixed telephony regulation. The principal amount of the fine imposed by ANATEL, and object of the lawsuit, totals R $199,075 . On December 31, 2022, and December 31, 2021, amount including interest and indexation accruals totaled approximately R $540,846 and R $499,415 , respectively. The Company believes that the fine imposed is illegal and not due based, fundamentally, on the following defense arguments: (i) ANATEL's error in determining the universe of users considered in the fine (the number of users affected is less than that considered by the ANATEL); and (ii) the calculation of the penalty is disproportionate and baseless. The process was sent for analysis and decision by the CADE Court; the MPF has yet to issue its opinion.

[**Table of Contents**](#TOC)

● Administrative proceeding pending at CADE, allegedly coordinated action between the companies Claro, Oi Móvel and the Company, which comprised the Rede Correios Consortium to compete in the electronic trading session no. 144/2015, carried out by the Brazilian Post and Telegraph Company; as well as alleged price discrimination by Company in relation to services offered to BT Brasil Serviços de Telecomunicações Ltda. ("BT"), contravening competitive protocols. In its defense, Company (i) states that the formation of consortia to participate in public tenders is legal and can promote competition; and (ii) demonstrates that there is no basis for allegation of discriminatory conduct, since: (a) the Company was not the only alternative to BT's supplier; and (b) prices of the service offered by the consortium cannot be compared to those quoted by BT, as they are of a difference technical nature, pricing and quantity of resources involved. On March 8, 2021, the Technical Note of the General Superintendence issued an opinion on the configuration of infractions of the economic order practiced by the companies. The process was forwarded by the technical area to the CADE Court , which decided that the operators engaged in anti-competitive conduct. And after this decision, the Company filed a motion for clarification, which is pending judgment.

● Term of Conduct Adjustment ("TAC") signed with ANATEL on February 28, 2022, effective for four years from publication in the DOU, on March 3, 2022. The TAC includes 24 PADOs relating to Quality, Interruptions and Users' Rights, in which the obligation to pay estimated and issued fines were exchanged for investments in 14 conduct adjustment commitments and an additional commitment to build a fiber backbone route. As the TAC became effective with its PADO commitments, in the nine-month periods ended September 30, 2022, The Company made write-offs totaling R $42 million and R $324 million in cases with probable and possible chances of loss, respectively.

● Proceedings initiated by ANATEL to investigate the inclusion of gains in the concession plans from decisions of the STF in which it excluded ICMS from the PIS/COFINS calculation basis between 2002 and 2017. The Attorney General's Office and ANATEL's technical area believe that such gains do not result from business efficiency, but from a change in the tax regulations. The return proposal suggested by ANATEL would be generated through a tariff review for basic plans and the construction of high capacity backhaul infrastructure for the alternative plans, approximating R $1 billion, for which management believes the risk of loss to be possible. The case will be judged by the Board of Directors of ANATEL, from which it may be challenged through an arbitration procedure .

● Procedure for the Determination of Noncompliance with Obligations ("PADO"), which deals with coverage targets whose applied fine of R $127 million could be converted into an obligation to do, which consists of an alternative means of complying with the sanction of the fine, for investment for installation 4G radio base station in 188 locations without this technology, whose installation should take place in 2 and a half years, with maintenance costs equivalent to the period of 1 year. Installation cannot result from ran sharing agreements, swaps, network rentals, industrial exploitation contracts, or other contractual means. After adherence and confirmation of consent by ANATEL, compliance within the specified period will be monitored .

● The Company is a party to lawsuits that discuss nullity of contractual clauses and obligations to do and not to do linked to the suspension of services, non-increase in tariffs, repairs and maintenance of poles, which do not involve a determined financial value and, at the current stage in found are invaluable. These processes are awaiting judgment in the courts .

**21) LOANS, FINANCING, DEBENTURES, LEASE, 5G LICENSES AND LIABILITIES FOR THE ACQUISITION OF A COMPANY**

**a) Accounting policy**

These are financial liabilities measured initially and recognized by fair value, net of costs incurred to obtain them and subsequently measured by amortized cost (plus pro-rata charges and interest), considering the effective interest rate of each operation, or by fair value through profit or loss.

Borrowing costs directly related to the acquisition, construction or production of an asset that necessarily requires more than 18 months to be completed for use or sale purposes are capitalized as part of the cost of the corresponding asset. The Company did not capitalize borrowing and financing costs and debentures due to the absence of qualifying assets.

[**Table of Contents**](#TOC)

*Leases*

On the lease start date, the Company and its subsidiaries recognize lease liabilities measured at the present value of lease payments to be made during the lease term. Lease payments substantially include fixed payments less any lease incentives receivable, variable lease payments that depend on an index or rate, and amounts expected to be paid under residual value guarantees. Lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Company and its subsidiaries and payments of fines for termination of the lease, for termination of the lease agreement.

When calculating the present value of lease payments, the Company and its subsidiaries use its incremental borrowing rate on the start date because the interest rate implicit in the lease is not easily determinable. After the commencement date, the amount of the lease liability is increased to reflect accrued interest and reduced for lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in lease payments (for example, changes in future payments resulting from a change in an index or rate used to determine such lease payments) or a change in the valuation of an option to call the underlying asset.

The present value of lease agreements is measured by discounting future fixed payment flows, which do not include projected inflation, at market interest rates, estimated using the Company's intrinsic risk spread.

The discount yield curves used are constructed based on observable data. Market interest rates were extracted from B3, and the Company's risk spread is estimated from debt securities issued by companies with comparable risk. The final discount curve reflects the Company's incremental loan interest rate.

**b) Critical estimates and judgments**

Determining the lease term of contracts that have renewal or termination option clauses. The Company and its subsidiaries determine the lease term as the non-cancellable contractual term, together with the periods included in a possible renewal option to the extent that such renewal is assessed as reasonably certain and with periods covered by an option to terminate the contract at to the extent that it is also assessed as reasonably certain. The Company and its subsidiaries have several lease agreements that include renewal and termination options.

The Company and its subsidiaries apply judgment when assessing whether it is reasonably certain whether or not to exercise the option to renew or terminate the lease. In this assessment, it considers all relevant factors that create an economic incentive to exercise renewal or termination. After the initial measurement, the Company and its subsidiaries reassess the lease term if there is a significant event or change in circumstances that is within their control and will affect their ability to exercise or not exercise the option to renew or terminate (for example, carrying out significant improvements or customizations to the leased asset).

The Company and its subsidiaries are not able to readily determine the interest rate implicit in the lease. Accordingly, this assessment requires Management to consider estimates when observable rates are not available or when they need to be adjusted to reflect the terms and conditions of a lease. The Company and its subsidiaries estimate the incremental rate using observable data (such as market interest rates), when available, and considers in this estimate aspects that are specific to the Company and its subsidiaries.

**a) Capital**

Pursuant to its Articles of Incorporation, the Company is authorized to increase its share capital up to 1,850,000,000 common shares without requiring it first to adjust its bylaws. The Board of Directors is authorized to deliberate any increase and consequent issue of new shares within this limit.

Brazilian Corporation Law (Law no. 6404/1976, Article 166, item IV) - establishes that capital may be increased by an Extraordinary Shareholders' Meeting Resolution by modifying the Articles of Incorporation, if the authorized capital increase limit has been reached.

[**Table of Contents**](#TOC)

The shareholders will have preemptive rights to subscribe for a capital increase, in proportion to their number of shares. By resolution of the Board of Directors, the preemptive right in the issuance of shares, convertible debentures and subscription bonus, whose placement may be made through sale on the Stock Exchange or public subscription, exchange for shares in a public offer for acquisition may be excluded control, under the terms of articles 257 and 253 of the Corporation Law, as well as enjoy tax incentives, under the terms of special legislation, as provided for in article 172 of the Corporation Law.

Shares issued by the Company owned by SPTE were delivered to its partners Telefónica and TLH, in proportion to their respective holdings in the Company's capital stock, within the scope of sharing the shareholders' equity. The liquidation of SPTE, the consequent termination of the Voting Agreement and the aforementioned delivery of shares did not result in a change in the composition of the Company's control (which was already indirectly held jointly by TLH, Telefónica and SPTE, all companies under common control of Telefónica), its administrative structure or its regular functioning.

#### 25) NET OPERATING REVENUE
**a) Accounting policy**

Total revenues from packages that combine several products or services (fixed, mobile, data, internet or television) are allocated to each performance obligation based on their independent selling prices in relation to the total consideration for the package and recognized when (or as soon as) the obligation is satisfied. When packages promote some discount on equipment or services, an accounting adjustment is made to allocate the sale price between them based on their fair price, constituting a contractual asset or liability, which is appropriated to income over subsequent periods.

Revenues correspond substantially to the provision of telecommunication services, communications, sales of goods, advertising and other revenues, and are presented net of taxes, discounts and returns (in the case of sale of goods), levied on them.

Revenues from sales of prepaid cellular recharge credits, as well as the respective taxes due, are deferred and recognized in income as the services are effectively provided.

Revenues from equipment leasing contracts, classified as leasing (Vivo TECH product), are recognized when the equipment is installed, when the effective transfer of risk occurs. Revenues are recognized at the present value of future minimum contract payments.

Revenue from the sale of handsets to dealers is accounted for upon delivery, when all risks and benefits are transferred to accredited agents.

Revenues from services and goods are basically subject to the following indirect taxes: ICMS or ISS, as the case may be, PIS and COFINS, as the case may be.

**b) Critical estimates and judgments**

The Company has billing systems for services with intermediate cut-off dates. Thus, at the end of each month there are revenues already received by the Company, but not effectively invoiced to its customers. These unbilled revenues are recorded based on estimates, which take into account historical consumption data, number of days elapsed since the last billing date, different cycles of information, and data obtained from different sources which is processed by a large number of application and system, among others. These estimates are subject to significant uncertainties.

#### 31) PENSION PLANS AND OTHER POST-EMPLOYMENT BENEFITS
**a)&nbsp;&nbsp;&nbsp;&nbsp;Accounting policy**

The Company and its subsidiaries individually sponsor pension funds of post-retirement benefits for active and retired employees, in addition to a multisponsor supplementary retirement plan and health care plan for former employees. Contributions are determined on an actuarial basis and recorded on an accrual basis. Liabilities relating to defined benefit plans are determined based on actuarial evaluations at each year-end, in order to ensure that sufficient reserves have been set up for both current and future commitments.

Actuarial liabilities related to defined benefit plans were calculated using the projected unit credit method. Actuarial gains and losses are recognized immediately in equity (in other comprehensive income).

For plans with defined contribution characteristics, the obligation is limited to the contributions payable, which are recognized in the P&L in the respective accrual periods.

The asset or liability related to defined benefit plan to be recognized in the financial statements corresponds to the present value of the obligation for the defined benefit (using a discount rate based on long-term National Treasury Notes - "NTNs"), less the fair value of plan assets that will be used to settle the obligations. Plan assets are assets held by a privately held supplementary pension plan entity. Plan assets are not available to the Company's creditors or those of its subsidiaries and cannot be paid directly to the Company or its subsidiaries. The fair value is based on information on market prices and, in the case of securities quoted, on the purchase price disclosed. The value of any defined benefit asset then recognized is limited to the present value of any economic benefits available as a reduction in future plan contribution from the Company.

Actuarial costs recognized in the statement of income are limited to the service cost and cost of interest on the defined benefit plan obligation. Any changes in the measurement of plan assets and obligations are initially recognized in other comprehensive income, and immediately reclassified to retained earnings in P&L.

The Company and its subsidiaries manage and individually sponsors a health care plan for retired employees and former employees with fixed contributions to the plan, in accordance with Law No. 9656/1998 (which provides for private health care and health insurance plans). As provided for in Articles 30 and 31 of said law, participants shall have the right to the health care plan in which they participated while they were active employees.

**b)&nbsp;&nbsp;&nbsp;&nbsp;Critical estimates and judgments**

The cost of pension plans with defined benefits and other post-employment health care benefits and the present value of the pension obligation are determined using actuarial valuation methods. Actuarial valuation involves use of assumptions about discount rates, future salary increases, mortality rates and future increases in pension and annuity benefits. The obligation for defined benefits is highly sensitive to changes in these assumptions. All assumptions are reviewed on an annual basis.

The mortality rate is based on publicly available mortality tables in the country. Future salary increases, and pension increases are based on expected future inflation rates for the country.

[**Table of Contents**](#TOC)

**c)&nbsp;&nbsp;&nbsp;&nbsp;Information on pension plans and other post-employment benefits**

The plans sponsored by the Company and its subsidiaries and the related benefit types are as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Plan** | **Type** | **Entity** | **Sponsor** |
| PBS-A | Defined benefit (DB) | Sistel | Telefônica Brasil, jointly with other telecoms resulting from privatization of the Sistema Telebrás |
| PAMA / PCE | Defined benefit (DB) | Sistel | Telefônica Brasil, jointly with other telecoms resulting from privatization of the Sistema Telebrás |
| Healthcare - Law No. 9656/98 | Defined benefit (DB) | Telefônica Brasil | Telefônica Brasil, Terra Networks, TGLog and TIS |

| Telefônica BD | Defined benefit (DB) | VisãoPrev | Telefônica Brasil |
| VISÃO | Defined contribution (DC) / Hybrid | VisãoPrev | Telefônica Brasil, Terra Networks, TGLog, TIS and CloudCo Brasil |

---

The Company has participation in the decisions that directly affect the governance of the plans, with members nominated for both the Deliberative Council and the Fiscal Council of the administrators Visão Prev Sociedade de Previdência Complementar ("Visão Prev") and Fundação Sistel de Seguridade Social ("Sistel").

The defined benefit obligation is made up of different components, according to the pension characteristic of each plan, and may include the actuarial liabilities of supplementary pension liabilities, health care benefits to retirees and dependents or compensation for death or disability of members. This liability is exposed to economic and demographic risks, such as: (i) increases in medical costs that could impact the cost of health care plans; (ii) salary growth; (iii) long-term inflation rate; (iv) nominal discount rate; and (v) life expectancy of members and pensioners.

The fair value of plan assets is primarily comprised of fixed income investments (NTN's, LFT's, LTN's, repurchase agreements, CDBs, debentures, letters of guarantee and FIDC shares) and equity investments (highly liquid, well regarded, large company shares and investments in market indices).

Due to the concentration of fixed income and floating rate investments plan assets are mainly exposed to the risks inherent in the financial market and economic environment such as: (i) market risk in the economic sectors where variable income investments are concentrated; (ii) risk events that impact the economic environment and market indices where variable income investments are concentrated; and (iii) the long-term inflation rate that may erode the profitability of fixed income investments at fixed rates.

The companies that administer post-employment benefits plans sponsored by the Company (Visão Prev and Sistel) seek to meet the flows of assets and liabilities through the acquisition of fixed income securities and other long-term assets.

With the exception of the Companhia Telefônica Brasileira ("CTB") and the healthcare plan under Law No. 9656/98, generally all benefit plans that have funds constituted present a surplus position. The economic benefit recorded in the Company's assets or that of its subsidiaries does not reflect the total surplus determined in these plans, as it only considers only the portion of the surplus which presents a real possibility of recovery. The means of plan surplus recovery is solely through reductions in future contributions and given that not all plans currently receive enough contributions for full recovery of surpluses, the economic benefit recorded under assets is limited to the total possible recovery amount in accordance with projected future contributions.

The position of plan assets is on December 31, 2022 and 2021, respectively, and plan assets were apportioned based on the Company's actuarial liabilities in relation to the total actuarial liabilities of the plan.

The actuarial gains and losses generated in each year are immediately recognized in equity (in other comprehensive income).

[**Table of Contents**](#TOC)

The following is a summary of the pension plans and other post-employment benefits:

c.1) Post-Employment Health Benefits Plans

The actuarial valuation made for the PAMA health plan used the registration of the participants with a base date of July 31, 2022, while the actuarial valuation made for the health plan Law No. 9,656/98 used the registration of the participants with a base date of August 31, 2022, both plans projected for December 31, 2022. For comparative exercises, the actuarial valuation made for the PAMA health plan used the registration of the participants with a base date of July 31, 2021, while the actuarial valuation made for the health plan Law No. 9,656/98 used the registration of the participants with a base date of August 31, 2021, both plans projected for December 31, 2021.

c.1.1) Healthcare Plan to Retirees and Special Coverage Program (PAMA and PAMA-PCE)

The funding procedure is the capitalization method and the sponsor's contribution are at the fixed percentage of payroll of employees covered by the Telefônica BD plan.

c.1.2) Health care plan – Law No. 9656/1998

The Company manages and together with its subsidiaries sponsors a health care plan to retired employees and former employees with fixed contributions to the plan, in accordance with Law No. 9656/98.

As provided for in Articles 30 and 31 of said law, participants shall have the right to the health care plan in which they participated while they were active employees. Benefitted participants are classified as (i) retirees and their dependents; and (ii) dismissed employees and their dependents.

c.2) Post-employment Social Security Plans

The actuarial valuation carried out for the CTB and PBS-A pension plans used the registration of participants with a base date of July 31, 2022, projected for December 31, 2022, and the registration of participants with a base date of July 31, 2021, projected for December 31, 2021.

The actuarial valuation carried out for the pension plans Telefônica BD and Plans Visão used the registration of participants with a base date of August 31, 2022, projected for December 31, 2022 and the registration of participants with a base date July 31, 2021, projected to December 31, 2021.

c.2.1) PBS Assisted Plan (PBS-A)

The PBS-A plan is a defined benefit private pension plan managed by Sistel and sponsored by the Company jointly with the other telecommunications companies originating in the privatization of the Telebrás System. The plan is subject to funding by sponsors in the case of any asset insufficiency to ensure pension supplementation of participants in the future.

The PBS-A plan comprises assisted participants of the Sistel Benefit Plan who were already retirees on January 31, 2000, from all the participating sponsors, with joint liability of all sponsors to the plan and Sistel.

[**Table of Contents**](#TOC)

According to PREVIC Ordinance No. 1,061, of December 5, 2019, published in the DOU on December 9, 2019, Sistel approved the distribution of part of its surplus, in the form of PBS-A's special reserve, with reversal of values to sponsors and improvement of benefits, in the form of temporary income, to those assisted.The participation corresponding to the Company in the distribution of this reserve was calculated in the amount of R$215,328, with expected distribution in the form of 36 monthly payments, corrected by the plan's income, already received in full by the Company (Note 11).

Even considering the distribution of the reserve approved by PREVIC, PBS-A still has assets in excess of actuarial obligations as of December 31, 2022 and 2021. These surpluses were not recognized due to the lack of legal provision for their reimbursement and, as they are not a contributory plan, no deduction is possible in future contributions.

c.2.2) CTB Plan

Contributions to the CTB plan are determined based on actuarial valuations prepared by independent actuaries, in accordance with the rules in force in Brazil. The funding procedure is the capitalization method and the sponsor's contribution are a fixed percentage of payroll of employees covered by the plan.

The Company also individually manages and sponsors the CTB plan, originally provided to former employees of CTB who were in the Company in 1977, with whom an individual retirement concession agreement was executed to encourage their resignation. This is an informal pension supplementation benefit paid to former employees directly by the Company. These plans are closed, and no other members are admitted.

c.2.3) Telefônica DB Plan

The Company individually sponsors the defined benefit retirement, Telefônica DB plan.

In order to improve allocation of Telefônica DB plan assets and analyze the coverage ratio of plan obligations in future years, a stochastic *Application Lifecycle Management ("ALM")* study was prepared by Visão Prev and Willis Towers Watson. This ALM study aimed at projecting the ratio between coverage of liabilities (solvency ratio) and the risk of mismatching measured by the standard deviation of the solvency ratio. The study concluded that the plan presents sustainable projection of their coverage ratio with the current investments' portfolio.

At the time of the concession, a benefit is calculated which will be paid in a lifelong form and updated by inflation. This plan is not open to new accessions.

The contributions are defined according to the costing plan, which is calculated considering financial, demographic and economic hypotheses in order to accumulate enough resources to pay the benefits to the participants who are already receiving them, and to the new pensions.

c.2.4) VISÃO Plans (Visão Telefônica and Visão Multi plans)

The Company and its subsidiaries sponsor defined contribution plans with defined benefit components (hybrid plans) and pension benefits, the Visão plans, managed by Visão Prev. The contribution is attributed to each subsidiary in the economic and demographic proportion of its respective obligation to the plan.

The contributions made by the Company and subsidiaries related to defined contribution plans totaled R$53,732 on December 31, 2022 (R$54,592 on December 31, 2021).

The contributions to the Visão Telefônica and Visão Multi plans are: (i) basic and additional contribution, with contributions made by the participant and sponsor; and (ii) additional, sporadic and specific contribution, with contributions made only by the participant.

In addition, the participant has the possibility to choose one of five investment profiles to apply to their balance, and they are: Super Conservative, Conservative, Moderate, Aggressive and Aggressive Fixed Income Long-Term.

In addition to the assumptions presented in the tables above, for 2022 and 2021 other assumptions common to all plans were adopted, as follows: (i) long-term inflation rate: 3.50% in 2022 and 3.25% in 2021; and (ii) annual increase in the use of medical services according to age: 4.0% for 2022 and 2021.

c.3.12) Changes in actuarial assumptions in relation to the prior year

In order to adjust some actuarial assumptions to the economic and demographic reality, a study was conducted for the plans administered by Visão Prev and Sistel, which adopted the definition of the assumptions in their Deliberative Councils.

The main economic and financial assumptions that have changed in relation to the previous fiscal year and that interfere with the defined benefit liability are: (i) rates for discount to present value of the defined benefit liability; (ii) long-term inflation rate; (iii) rate of future wage growth; (iv) rate of growth of medical costs; and (v) annual nominal index of adjustment of social security benefits.

The impacts on the plans' defined benefit liabilities due to the new definition of the actuarial assumptions are as follows:

c.3.13) Sensitivity analysis for actuarial assumptions

The Company believes that the significant actuarial assumptions with reasonable likelihood of variation due to financial and economic scenarios, which could significantly change the amount of the defined benefit obligation, are the discount rate used to adjust the defined benefit liability to present value and the rate of growth of medical costs.

[**Table of Contents**](#TOC)

Below, we present a sensitivity analysis on the defined benefit obligation for scenarios of increase and decrease in the discount rate used to adjust the defined benefit liability to present value and in the growth rate of medical costs.

Due to the concentration of investments in fixed and variable income, plan assets are exposed mainly to risks inherent to the financial market and the economic scenario, such as: (i) market risk in the economic sectors where investments in variable income are concentrated; (ii) risk of events that impact the economic scenario and market indices where variable income investments are concentrated; and (iii) long-term inflation rate that can consume the profitability of investments in fixed income with pre-fixed remuneration.

The administrators of post-employment benefit plans sponsored by the Company (Visão Prev and Sistel) seek to match asset and liability flows through the acquisition of fixed income securities and other long-term assets.

#### 32) FINANCIAL INSTRUMENTS AND RISK AND CAPITAL MANAGEMENT
**a) Accounting policy**

a.1) Financial assets

*Initial recognition and measurement*

On initial recognition, a financial asset is classified in the following measurement categories: (i) at fair value through profit or loss; (ii) at amortized cost; or (iii) at fair value through other comprehensive income, depending on the situation.

The classification of financial assets at initial recognition depends on the contractual cash flow characteristics of the financial asset and the business model for the management of these assets.

[**Table of Contents**](#TOC)

For a financial asset to be classified and measured at amortized cost or at fair value through other comprehensive income, it needs to generate cash flows that are "exclusively payments of principal and interest" on the principal amount outstanding. This assessment is carried out at the level of each financial instrument.

Financial assets with cash flows that are not exclusively payments of interest principal are classified and measured at fair value through profit or loss, regardless of the business model adopted.

The Company's business model for managing financial assets refers to how it manages its financial assets to generate cash flows. The business model determines whether cash flows will result from the collection of contractual cash flows, the sale of financial assets or both. Financial assets classified and measured at amortized cost are maintained in a business plan with the objective of maintaining financial assets in order to obtain contractual cash flows while financial assets classified and measured at fair value against other comprehensive income are maintained in a business model. with the objective of obtaining contractual cash flows and for the purpose of sale.

The Company's consolidated financial assets include cash and cash equivalents, trade accounts receivable,financial investments and derivative financial instruments.

*Subsequent measurement* 

Subsequent measurement of financial assets depends on their classification, as follows:

Financial assets at fair value through profit or loss: these assets are subsequently measured at fair value. Net income, including interest, is recognized directly in income.

Financial assets at amortized cost: these assets are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in income. Any gain or loss on derecognition is recognized in profit or loss.

Financial assets at fair value through other comprehensive income: these assets are subsequently measured at fair value. Interest income is calculated using the effective interest method, and foreign exchange gains and losses and impairment are recognized in profit or loss. Other net income is recognized in other comprehensive income. In derecognition, the accumulated result in other comprehensive income is reclassified to the statement of income.

*Derecognition*

A financial asset (or, whenever the case, a part of a financial asset, or a part of a group of similar financial assets) is derecognized when: (i) the rights to receive the cash flows from the asset have expired; or (ii) the Company has transferred its rights to receive cash flows from it has assumed obligation to pay the received cash flows in full without material delay to a third part under a 'pass-through' arrangement; and either (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

*Impairment of financial assets*

The Company and its subsidiaries apply an impairment model for financial assets based on expected credit losses, using a simplified method for certain short and long-term assets (commercial receivables, lease receivables and contractual assets).

[**Table of Contents**](#TOC)

Under this simplified approach, credit impairment is recognized by reference to expected credit losses over the life of the asset. For this purpose, the Company and its subsidiaries use matrices based on historical bad debt experience by geographical area on a portfolio segmented by customer category according to credit pattern. The matrix for each category has a defined time horizon divided into intervals in accordance with the collection management policy and is fed with historical data that covers at least 24 collection cycles. This data is updated on a regular basis. Based on the information observable at each close, the Company and its subsidiaries assess the need to adjust the rates resulting from these matrices, considering current conditions and future economic forecasts.

a.2) Financial liabilities

*Initial recognition and measurement*

Upon initial recognition, a financial liability is classified into the following measurement categories: (i) at fair value through profit or loss; (ii) at amortized cost; or (iii) derivatives designated as hedge instruments in an effective hedge, as appropriate.

Financial liabilities are initially recognized at fair value plus, in the case of loans and financing, transaction cost directly attributable thereto.

The Company's consolidated financial liabilities include accounts payable to suppliers, loans, financing, debentures, leases, 5G licenses, liabilities for the acquisition of a companies, derivative financial instruments, obligations with ANATEL, amounts to be refunded to customers and obligations with related parties

*Subsequent measurement* 

Measurement of financial liabilities depends on their classification, as follows:

Financial liabilities at fair value through profit or loss: financial liabilities are designated at initial recognition at fair value through profit or loss. This category also includes derivative financial instruments contracted, except those designated as derivative financial instruments of cash flow hedge. Interest, monetary and exchange variations and changes arising from the valuation at fair value, when applicable, are recognized in the statement of income when incurred.

Financial liabilities at amortized cost: after initial recognition, loans and financing subject to interest are subsequently measured at amortized cost using the effective interest rate method. Gains and losses are recognized in the statement of income at the time of write-off of liabilities, as well as during the amortization process using the effective interest rate method.

Amortized cost is calculated taking into account any discount or goodwill on acquisition and fees or costs that are an integral part of the effective interest rate method. Amortization using the effective interest rate method is included as a financial expense in the income statement.

*Derecognition*

A financial liability is derecognized when the obligation has been revoked, cancelled or expired. When an existing financial liability is replaced by another of the same lender, and the terms of the instruments are substantially different, or when the terms of an existing debt instrument are substantially modified, this replacement or modification is treated as derecognition of the original liability and recognition of a new liability, and the difference in the corresponding carrying amounts is recognized in the statement of income.

a.3) Fair value measurement 

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Fair value measurement is based on the assumption that the transaction to sell the asset or transfer the liability will take place (i) in the principal market for the asset or liability; and (ii) in the absence of a principal market, in the most advantageous market for that asset or liability. The Company and or its subsidiaries must have access to the principal (or most advantageous) market.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing an asset or liability, assuming that market participants act in their best economic interests.

[**Table of Contents**](#TOC)

Fair value measurement of a non-financial asset takes into consideration the capacity of a market participant to generate economic benefits through the best use of the asset or selling it to another market participant that would also make the best use of the asset.

The Company and its subsidiaries use adequate valuation techniques in the circumstances and for which there is sufficient data to measure the fair value, that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs.

The fair values of all assets and liabilities are classified within the fair value hierarchy described below, based on the lowest level of information that is significant to the fair value measurement as a whole:

Level 1: quoted market prices (unadjusted) in active markets for identical assets or liabilities.

Level 2: valuation techniques for which there is a significantly lower level of information to measure the fair value directly or indirectly observable; and

Level 3: valuation techniques for which the lowest and significant level of information to measure the fair value is not available.

For assets and liabilities recurrently recognized in the financial statements, the Company determines whether there were transfers between the hierarchy levels, revaluating the classification (based on the lowest level input that is significant to the overall fair value measurement) at the end of each reporting period.

The Company and its subsidiaries assessed their financial assets and liabilities in relation to market values using available information and appropriate valuation methodologies. Both the interpretation of market data and the selection of valuation methods require considerable judgment and reasonable estimates to produce the most adequate realization value. As a result, the estimates shown do not necessarily indicate amounts that could be realized in the current market. The use of different assumptions for the market and/or methodologies may have a material effect on estimated realization values.

In the years ended December 31, 2022 and 2021, there were no transfers of fair value assessments between the aforementioned levels.

a.4) Financial instruments – net

Financial assets and liabilities are presented net in the balance sheet if, and only if, there is a current enforceable legal right to offset the amounts recognized and if there is an intention to offset or realize the asset or settle the liability simultaneously.

a.5) Derivative financial instruments and hedge accounting

A hedge relationship qualifies for hedge accounting if it meets all of the following effectiveness requirements: (i) there is an economic relationship between the hedged item and the hedging instrument; (ii) the credit risk effect does not influence the changes in value that result from this economic relationship; and (iii) the hedge ratio of the hedging relationship is the same as that resulting from the amount of the hedged item that the entity effectively protects and the amount of the hedge instrument that the Company effectively uses to protect that amount of hedged item.

The documentation includes identification of the hedging instrument, the hedged item or transaction, the nature of the hedged risk, the nature of the risks excluded from the hedge relationship, the prospective statement of hedge effectiveness and how the Company shall assess the effectiveness of changes in the hedging instrument's fair value in offsetting the exposure to changes in the hedged item's fair value or cash flows attributable to the hedged risk.

On the inception initial recognition of a hedge relationship, the Company formally designates and documents the hedge relationship to which it wishes to apply hedge accounting, the risk management objective and strategy for undertaking the hedge.

The Company uses derivative financial instruments, such as currency and interest rate swaps or currency non- deliverable forward contracts to hedge against currency risks.

[**Table of Contents**](#TOC)

Derivative financial instruments designated in hedge transactions are initially recognized at fair value on the date on which the derivative contract is entered into, and subsequently revalued also at fair value. Derivatives are presented as financial assets when the fair value of the instrument is positive and as financial liabilities when the fair value of the instrument is negative.

Any gains or losses resulting from changes in fair value of derivatives during the year are posted directly to the statement of income, except for the effective portion of cash flow hedges, which is recognized directly in equity as other comprehensive income and subsequently reclassified to P&L when the hedged item affects P&L.

For the purpose of hedge accounting, hedges are classified as cash flow hedges and fair value hedges. The Company's contracts are classified as cash flow hedges when they provide protection against changes in cash flows that are attributable to a particular risk associated with a recognized liability that may affect the profit or loss and fair value when they provide protection against exposure to changes in the fair value of the identified part of certain liabilities that is attributable to a particular risk (exchange variation) and may affect the profit or loss.

Cash flow hedges

Cash flow hedges meeting the recording criteria are accounted for as follows: (i) the portion of gain or loss from the hedge instrument determined as an effective hedge shall be recognized directly in equity (other comprehensive income), and (ii) the ineffective portion of gain or loss from the hedge instrument shall be recognized in the statement of income.

When the Company's documented risk management strategy for any given hedge relationship excludes from the hedge effectiveness evaluation any particular component of gain or loss or the corresponding cash flows from the hedge instrument, that gains or loss component is recognized in financial income (expenses).

Amounts recorded in other comprehensive income are immediately transferred to the statement of income when the hedged transaction affects P&L. When a hedged item is the cost of a non-financial asset or liability, amounts recorded in equity are transferred at the initial carrying amount of the non-financial assets and liabilities.

If the hedging instrument expires or is sold, terminated or exercised without replacement or rollover (as part of the hedging strategy), or if its designation as a hedge is revoked, or when the hedge fails to meet the hedge accounting criteria, any cumulative gain or loss previously recognized in other comprehensive income remains separately in equity until the forecast transaction occurs or the firm commitment is fulfilled.

Fair value hedges

Fair value hedges meeting the accounting criteria are accounted for as follows: (i) gain or loss from changes in fair value of a hedge instrument shall be recognized in the statement of income as finance costs; and (ii) gain or loss from a hedged item attributable to the hedged risk shall adjust the recorded amount of the hedged item to be recognized in the statement of income, as finance costs.

For fair value hedges relating to items carried at amortized cost, any adjustment to carrying amount is amortized through profit or loss over the remaining term of the hedge using the effective interest method. The effective interest rate amortization may begin as soon as any adjustment exists and no later than the point that the hedged item ceases to be adjusted for changes in its fair value attributable to the risk being hedged.

If the hedged item is derecognized, the unamortized fair value is recognized immediately in the statement of income.

When an unrecognized firm commitment is designated as a hedged item, the subsequent cumulative change in the fair value of the firm commitment attributable to the hedged risk is recognized as an asset or liability with a corresponding gain or loss recognized in profit and loss.

Classification between current and non-current

Derivative financial instruments are classified as current and non-current or segregated into short and long-term portions based on an evaluation of the contractual cash flows.

[**Table of Contents**](#TOC)

When the Company maintains a derivative as an economic hedge (and does not apply hedge accounting), for a period exceeding 12 months after the balance sheet date, the derivative is classified as non-current (or segregated into current and non-current portions), in line with the classification of the corresponding item.

The derivative instrument is segregated into current and non-current portions only when amounts can be reliably allocated.

Derivative instruments that are designated as effective hedging instruments are classified consistently with the classification of the underlying hedged item.

**b) Critical estimates and judgments**

When the fair value of financial assets and liabilities stated in the balance sheet cannot be obtained in active markets, it will be determined using valuation techniques, including the discounted cash flow method. Data for these methods is based on those adopted in the market, whenever possible. However, when this is not feasible, a certain level of judgment is required for fair value determination. Judgment includes consideration of the inputs used, such as liquidity risk, credit risk and volatility. Changes in the assumptions about these factors could affect the reported fair value of financial instruments.

**c) Derivative transactions**

The derivative financial instruments contracted by the Company are mainly used for hedging against foreign exchange risk from assets and liabilities in foreign currency and the effects of inflation on leases indexed to the IPCA. There are no derivative financial instruments held for speculative purposes, possible currency risks are hedged.

Management believes that the Company's internal controls for its derivatives are adequate to control risks associated with each strategy for the market. Gains/losses obtained or sustained by the Company in relation to its derivatives show that its risk management has been appropriate.

Whilst these derivative contracts qualify for hedge accounting, the hedged item is adjusted to fair value, offsetting the result of the derivatives, pursuant to the rules of hedge accounting. This hedge accounting applies both to financial liabilities and probable cash flows in foreign currency.

Derivatives contracts include specific penalties for breach of contract. Breach of contract provided for in agreements made with financial institutions leads to the anticipated liquidation of the contract.

On December 31, 2022 and 2021, the Company held no embedded derivatives contracts.

c.1) Fair value of derivative financial instruments

The valuation method used to calculate the fair value of financial liabilities (if applicable) and derivative financial instruments was the discounted cash flow method, based on expected settlements or realization of liabilities and assets at market rates prevailing at the balance sheet date.

The fair values of the positions in Reais are calculated by projecting future inflows from transactions using B3 yield curves and discounting these flows to present value using market DI rates for swaps announced by B3.

The market values of foreign exchange derivatives were obtained using the market exchange rates in effect at the balance sheet date and projected market rates obtained from the currency's coupon-rate yield curves. The linear convention of 360 calendar days was used to determine coupon rates of positions indexed in foreign currencies, while the exponential convention of 252 business days was used to determine coupon rates for positions indexed to CDI rates.

[**Table of Contents**](#TOC)

Consolidated derivatives financial instruments shown below are registered with B3 and classified as swaps, usually, that do not require margin deposits.

For the purposes of preparing its financial statements, the Company adopted the fair value hedge accounting methodology for its foreign currency swaps x CDI and IPCA x CDI for hedging or financial debt. Under this arrangement, both derivatives and hedged risk are recognized at fair value.

On December 31, 2022 and 2021, the transactions with derivatives generated a negative consolidated net result of R$105,522 and R$12,690, respectively (Note 28).

*c.4)* Sensitivity analysis to the Company's risk variables

CVM Resolution 475/2008 requires listed companies to disclose sensitivity analyses for each type of financial instruments market risk that management believes to be significant at the end of each period, including all derivative financial instrument transactions.

Each financial instrument derivative transactions were assessed, and assumptions included a probable base scenario and a further two stressed scenario that could adversely impact the Company.

For the probable scenario, at the maturity dates for each of the transactions, the market rates sourced from B3 yield curves (currencies and interest rates) were used plus data from the IBGE, Central Bank, FGV, among others. In the probable scenario, there is no impact on the fair value of the above-mentioned derivatives. For scenarios II and III, as per the CVM rule, risk variables were stressed by 25% and 50% respectively.

[**Table of Contents**](#TOC)

Since the Company only holds derivatives to hedge its foreign currency assets and liabilities, changing scenarios are tracked by the corresponding hedged items the effects are almost non-existent. For these transactions, the Company reported the consolidated net exposure in each of the above-mentioned three scenarios on December 31, 2022.

The assumptions used by the Company for the sensitivity analysis on December 31, 2022 were as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Risk Variable** | **Probable** | **25% depreciation** | **50% depreciation** |

| CDI | 13.65% | 17.06% | 20.48% |

---

For calculation of the net exposure for the sensitivity analysis, all derivatives were considered at market value and hedged items designated for hedges for accounting purposes were also considered at fair value.

The fair values shown in the table above are based on the portfolio position on December 31, 2022, but do not reflect an estimate for realization due to the dynamism of the market, which is constantly monitored by the Company. The use of different assumptions could significantly affect the estimates.

**d) Classification of financial assets and liabilities by category and fair value hierarchy**

For the purposes of disclosing fair value, the Company and its subsidiaries determined classes of assets and liabilities based on the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy. Below, we present the composition and classification of financial assets and liabilities as of December 31, 2022 and 2021.

**e) Capital management**

The purpose of the Company's capital management is to ensure maintenance of a high credit rating and an optimal capital ratio to support the Company's business and maximize shareholder value.

The Company manages its capital structure by making adjustments and adapting to current economic conditions. In seeking such equilibrium, the Company may pay dividends, obtain new loans, issue debentures and contract derivatives. For the year ended December 31, 2022, there were no changes in capital structure objectives, policies or processes.

The Company includes in the net debt structure the balances of loans, financing, debentures, leases, 5G licenses, contractual retention and contingent liabilities arising from the acquisition of Companies (note 2.d) and derivative financial instruments, less cash and equivalents cash, financial investments in FIDC and accounts receivable from credit rights (FIDC Vivo Money).

The Company's ratio of consolidated debt to shareholders' equity consists of the following:

---

**f) Risk management policy**

The Company and its subsidiaries are exposed to several market risks as a result of its commercial operations, debts contracted to finance its activities and debt-related financial instruments.

f.1) Currency Risk

The Company is exposed to the foreign exchange risk for financial assets and liabilities denominated in foreign currencies, which may generate a smaller amount receivable or larger amount payable depending on the exchange rate in the period.

Hedging transactions were executed to minimize the risks associated with exchange rate on financial assets and liabilities in foreign currencies. This balance is subject to daily changes due to the dynamics of the business. However, the Company intends to cover the net balance of these assets and obligations (US$26,979 thousand, €17,264 thousand and £66 thousand paid by December 31, 2022, and US$21,129 thousand, €14,124 thousand and £66 thousand paid by December 31, 2021) to mitigate its foreign exchange risks.

f.2) Interest and Inflation Risk

This risk may arise from an unfavorable change in the domestic interest rate, which may adversely affect financial expenses from the portion of debentures referenced to the CDI and liability positions in derivatives (currency hedge and IPCA) pegged to floating interest rates (CDI).

To reduce exposure to the floating interest rate (CDI), the Company and its subsidiaries invested cash equivalents of R$2,220,385 and R$6,344,942 on December 31, 2022, and December 31, 2021, respectively, mostly in short-term CDI-based financial investments (CDBs). The carrying amounts of these instruments approximate their fair values, as they may be redeemed in the short term.

f.3) Liquidity Risk

Liquidity risk consists of the possibility that the Company might not have sufficient funds to meet its commitments due to the different timing and settlement terms of its rights and obligations.

[**Table of Contents**](#TOC)

The Company structures the maturities of financial instruments so as not to affect their liquidity.

The Company's cash flow and liquidity are managed on a daily basis by the operating departments to ensure that cash flows and contracted funding, when necessary, are sufficient to meet scheduled commitments in to mitigate liquidity risk.

The maturity profile of consolidated financial liabilities includes future principal and interest amounts up to the maturity date. For fixed rate liabilities, interest was calculated based on the indices established in each contract. For variable rate liabilities, interest was calculated based on the market forecast for each period.

f.4) Credit Risk

The credit risk arises from the possibility of the Company and its subsidiaries incurring losses due to difficulty in receiving amounts billed to their customers and sales of prepaid handsets and cards that have been pre-activated for the distribution network.

The credit risk on accounts receivable is diversified and mitigated by strict control of the customer base. The Company constantly monitors the level of accounts receivable from invoiced services and limits bad credit risk by interrupting telephone services if bills are past due. The mobile customer base predominantly uses the prepaid system, which requires purchase of credits beforehand and therefore does not pose credit risk. Exceptions are made for emergency services that must be maintained for security or national defense.

Credit risk on sales of pre-activated prepaid handsets and cards is managed through a prudent policy for granting credit, using modern credit scoring methods, analyzing financial statements and consultations to commercial databases, in addition to requesting guarantees.

The Company and its subsidiaries are also subject to credit risk arising from their investments, letters of guarantee received as collateral for certain transactions and receivables from derivative transactions. The Company and its subsidiaries control the credit limits granted to each counterpart and diversify this exposure across first-tier financial institutions as per current credit ratings of financial counterparties.

f.5) Environmental Risks

The Company's operations and properties are subject to various environmental laws and regulations that govern environmental licenses and registrations, protection of fauna and flora, atmospheric emissions, waste management and remediation of contaminated areas, among others. If the Company is unable to comply with current and future legal requirements, or identify and manage new or existing environmental liabilities, it may incur significant costs, which include investigation and remediation costs, indemnities, compensation, conduct adjustment, fines, suspension of activities and other penalties, investments to improve our facilities or change our operations, as well as reputational damage.

The identification of new significant environmental issues, changes in assessment criteria by regulatory agencies, more restrictive laws and regulations or other unforeseen events may result in significant environmental liabilities and their respective costs. The occurrence of any of these factors could have a material adverse effect on the Company's business, results of operations and financial condition. According to article 75 of Law No. 9,605/1998, the maximum fine for non-compliance with the environmental law is R$50,000 (fifty million), plus losses related to embargoes or administrative sanctions, in addition to indemnities and repairs for damages caused to the environment.

Climate change poses a series of potential environmental risks for telecommunications operators, including the Company, both from a regulatory and operational perspective. The increase in the intensity and frequency of extreme precipitation events, cyclones, floods and fires may damage, suspend or interrupt the Company's transmission operations for an indefinite period. If successive serious natural disasters occur, the Company may not have sufficient resources to repair its infrastructure in a timely and cost-effective manner.

In a simulation, an increase in temperature directly affected the operational conditions of the Company's network equipment, causing failures, accelerated wear and loss of assets and, therefore, increases in the risks of service interruptions. Cooling equipment essential for the Company's operation. Therefore, global warming may also increase the need for cooling with higher energy use and operating costs.

[**Table of Contents**](#TOC)

The telecommunications industry is not heavily reliant on fossil fuels but is very dependent on electricity for its networks. An increase in electricity prices could have a significant impact the Company's operating expenses. The estimated economic impact of this risk classifies it as substantive, through to a foreseeable horizon in 2030.

To manage climate risks, the Company encourages energy efficiency programs and plans for renewable energy and distributed energy generation. It also has a dedicated business continuity area, guided by the Global Business Continuity Regulation ("GBC"), which prescribes the preventive risk management, ensuring the resilience of its operations before any possible interruption.

f.6) Risks Relating to the Brazilian Telecommunications Industry and the Company

The Company's business is subject to extensive regulation, including any regulatory changes that may occur during the terms of the concession agreements and the Company's authorizations to provide telecommunication services in Brazil. ANATEL, oversees, among other matters: industry policies and regulations; licensing (including licensing of spectrum and bidding processes); fees and tariffs; competition, incentives and competitive aspects (including the Company's ability to grow by acquiring other telecommunications businesses); service, technical and quality standards; consumer rights; penalties and other sanctions related to interconnection and agreements; in addition to related obligations to the universalization of services.

The Brazilian telecommunications regulatory framework is continuously evolving. The interpretation and enforcement of regulations, the assessment of compliance with regulations and the flexibility of regulatory authorities are all marked by uncertainty. The Company operates under authorizations and a concession from the Brazilian government, and the ability to maintain these authorizations and concession is a precondition to the Company's success. However, because of the changing nature of the Brazilian regulatory framework, the Company cannot guarantee that ANATEL will not adversely modify the terms of the Company's authorizations and/or licenses. Accordingly, the Company's operating authorizations and licenses, must meet specific requirements and maintain minimum quality, coverage and service standards. Any failure to comply with these requirements may result in the imposition of fines, penalties and/or other regulatory responses, including the termination of the Company's operating authorizations and concession. Any partial or total termination of any of the Company's operating authorizations and licenses or the Company's concession would have a material adverse effect on the Company's business, financial condition, revenues, results of operations and prospects.

In recent years, ANATEL has reviewed and introduced regulatory changes, especially regarding asymmetric competition measures and interconnection fees charged among local providers of telecommunications services. Asymmetric competition measures may include regulations aimed at rebalancing markets where one participant has significantly different market share over other competitors. The adoption of disproportionately asymmetric measures could have a material adverse effect on the Company's business, financial condition, revenues, results of operations and prospects.

In this sense, it is important to emphasize that the regulatory agenda for the 2023-2024 biennium of ANATEL includes the revision of the General Plan of Competition Goals ("PGMC") (Resolution No. 600, of November 8, 2012, updated by Resolution No. 694, of 17 of July 2018) uniting in a single normative instrument a set of measures aimed at promoting competition and milestones for future reassessments on the performance of sectoral competition, four years, with the reassessment of the Relevant Markets in the sector, the asymmetric regulatory measures and the holders of Significant Market Power - PMS previously established by the regulation itself.

Complementing the PGMC review, UPI's recent acquisition of the mobile assets of OI Móvel S.A. by the three largest operators in the Brazilian SMP market (Vivo, Claro and TIM) ("Operation"), raised competition concerns identified by ANATEL and CADE, which imposed regulatory remedies in order to preserve the conditions of competition in the relevant markets affected by the Operation, among which: (i) Reference Offer in the Relevant National Roaming Market; (ii) Reference Offer for exploring the Personal Mobile Service - SMP through Virtual Network (MVNO); (iii) Offer of Temporary and Onerous Assignment of Radio Frequency Use Rights; (iv) Industrial Network Exploration Offer.

Regarding the reference offer in the relevant national roaming market, the version published to the market to comply with the aforementioned regulatory remedy uses as a basis the reference values approved and calculated by ANATEL, based on the application of a new methodology to study the national roaming market cost model (LRIC+ bottom-up model - Act No. 8822/2022). As a result of the change in the methodology used, the new reference values show a significant reduction when compared to the reference values previously in force (FAC-HCA top down model - Act No. 9157/2018).

[**Table of Contents**](#TOC)

In the general context above, the adoption of disproportionately asymmetric measures and the prospect of adoption, by ANATEL, of concepts, prices and remuneration models that may impact the remuneration and cost scenario, could substantially harm the business, financial situation, revenues, results operations and prospects of the Company.

With regard to interconnection fees are an important part of the Company's revenue and cost bases. These fees are charged among telecommunications service providers in order to allow and remunerate the interconnected use of their networks. To the extent that changes to the rules governing interconnection fees reduce of fees the Company can receive, or ability to collect such fees, the Company's businesses, financial conditions, revenues, results of operations and prospects could be adversely affected.

Therefore, the Company's business, results of operations, revenues and financial conditions could be negatively affected by the actions of the Brazilian authorities, including, in particular, the following: the introduction of new or stricter operational and/or service requirements; the granting of operating licenses in the Company's areas; limitations on interconnection fees the Company may charge to other telecommunications service providers; imposition of significant sanctions or penalties regarding failures to comply with regulatory obligations; delays in the granting of, or the failure to grant, approvals for rate increases; and antitrust limitations imposed by ANATEL and CADE.

f.7) Insurance Coverage

The policy of the Company and its subsidiaries, as well as the Telefónica Group, is to contract insurance coverage for all assets and liabilities with significant and high-risk amounts, based on Management's judgment and following Telefónica corporate program guidelines.

On December 31, 2022, the maximum limits of claims (established pursuant to the agreements of each entity consolidated by the Company) for significant assets, liabilities or interests covered by insurance and their respective amounts were R$900,000 for operational risks (including business interruption) and R$75,000 for general civil liability.

The independent auditors' scope of work does not cover reviewing the sufficiency of the insurance coverage, which was determined by the Company's Management and which it considers sufficient to cover potential claims.

f.8) Compliance

The Company complies with Brazilian anti-corruption laws and regulations in the jurisdictions in which its securities traded. In particular, the Company is subject, in Brazil, to the Law n 12.846/2013 and Decree No. 11.129/2022 and, in the United States, to the U.S. Foreign Corrupt Practices Act of 1977.

Although the Company has internal policies and procedures designed to ensure compliance with these anti-corruption laws and regulations, there can be no assurance that such policies and procedures will be sufficient or that the Company's employees, directors, officers, partners, agents and service providers individually adopt any type of action in violation of the Company's policies and procedures (or otherwise in violation of the relevant anti-corruption laws and regulations) for which the Company may be ultimately held responsible. Violations of anti-corruption laws and regulations could lead to financial penalties, damage to the Company's reputation or other legal consequences that could have a material adverse effect on the Company's business, results of operations and financial condition.

The Company develops and implements initiatives to ensure the continuous improvement of its Compliance Program, through a robust organizational and governance structure that guarantees a performance based on ethics, transparency and respect for applicable laws and standards.

As a result of the Company's commitment to maintaining a robust Compliance Program, in 2020, 2021 and 2022, the Company obtained the DSC 10,000 certificate (Guidelines for the Compliance System), which demonstrates the evolution of its Compliance Program over the last few years.

The Company's Extraordinary Shareholders' Meeting, held on February 1, 2023, approved the merger of Garliava ("Merger"), as described in the material fact disclosed by the Company on December 16, 2022 (note 1.d.6).

The Merger depends on obtaining prior consent from ANATEL and the conclusion of operational procedures related to systemic parameterization. In view of this, the effectiveness of the resolution is conditioned to a new resolution by the Company's Board of Directors, in a meeting to be held especially for this purpose, to verify the occurrence of said conditions, when, then, the Merger will become effective.

The approved Merger will not result in a capital increase, issuance of new shares or change in the Company's shareholdings, therefore, there is no need to talk about the replacement of shares or withdrawal rights.

c) Credit of Interest on Equity Intermediaries

At a meeting held on February 15, 2023, the Company's Board of Directors approved, ad referendum of the General Shareholders' Meeting to be held in 2024, the credit of interest on equity, for the fiscal year 2023, pursuant to the terms of Article 26 of the Company's Bylaws, Article 9 of Law No. 9,249/1995 and CVM Resolution No. 143/2022, in the gross amount of R$106,000, equivalent to 0.063772 per share, corresponding to an amount net of withholding income tax of R$90,100, equivalent to 0.054206 per share, calculated based on the balance sheet of January 31, 2023. The amount of interest on equity per share informed above may be subject to future adjustments, until February 28, 2023, due to possible acquisitions of shares under the Company's Share Buyback Program.

The payment of these proceeds will be made until July 31, 2024, on a date to be defined by the Company's Board of Directors and timely communicated to the market, being credited individually to the shareholders, obeying the shareholding position contained in the Company's records at the end of February 28th from 2023.

**DESCRIPTION OF SECURITIES**

**REGISTERED UNDER SECTION 12 OF THE EXCHANGE ACT**

As of December 31, 2022, Telefônica Brasil S.A. ("we," "us," and "our") had the following series of securities registered pursuant to Section 12(b) of the Exchange Act:

---

| | | |
|:---|:---|:---|
| **Title of each class** | **Trading Symbol(s)** | **Name of each exchange on which registered** |
| Common Shares, without par value\*  | VIVT3 | New York Stock Exchange\* |
| American Depositary Shares (as evidenced by American Depositary Receipts), each representing one Common Share | VIV | New York Stock Exchange |

---

------

\*Not for trading purposes, but only in connection with the registration on the New York Stock Exchange of American Depositary Shares representing those Common Shares.

The trading market for our common shares is the São Paulo Stock Exchange - *B3 S.A. – Brasil, Bolsa, Balcão* ("B3"). Our common shares trade under the symbol "VIVT3" (formerly TLPP3). In the United States, the common shares trade in the form of American Depositary Receipts ("ADRs"), each representing one common share, issued by Citibank N.A., as depositary, pursuant to a deposit agreement, among us, the depositary and the registered holders and beneficial owners from time to time of ADRs (the "Deposit Agreement").

The ADRs representing preferred shares commenced trading on the NYSE on November 16, 1998 and upon the Conversion (as described below) of all our preferred shares into common shares effective as of market close on November 20, 2020, our ADRs backed by preferred shares were exchanged for ADRs backed by common shares, trading in ADRs representing preferred shares was suspended as of November 23, 2020, and trading in ADRs representing common shares recommenced on the same date, and are traded on NYSE under the symbol "VIV" (formerly TSP).

At an extraordinary shareholders' meeting held on October 1, 2020, our shareholders approved, effective as from such date, among other things: (1) the conversion of all of our preferred shares into common shares, at a ratio of one common share for each preferred share (the "Conversion"); and (2) amendments to our by-laws*.* At a special meeting of holders of our preferred shares, held on that same date, our preferred shareholders ratified the conversion of all of our preferred shares into common shares. After the concession and the expiration of the term for shareholders to exercise withdrawal rights, we proceeded with the Conversion, and the last trading session for our preferred shares on the B3 and for our ADSs backed by preferred shares on the NYSE was on November 20, 2020. Therefore, as of November 23, 2020, "VIVT3" represents the only ticker symbol for trading of the Company's common shares on the B3, and ADSs backed by our common shares began trading on the NYSE under the ticker symbol "VIV." In connection with this listing (but not for trading) and upon the Conversion, our common shares are registered under Section 12(b) of the Exchange Act.

This exhibit contains a description of the rights of (i) the holders of common shares and (ii) ADR holders. Common shares underlying the ADSs are held by a Brazilian custodian, as agent for the depositary, and holders of ADSs will not be treated as holders of the Common shares.

The following summary is subject to and qualified in its entirety by Telefônica Brasil S.A.'s bylaws and of Law No. 6,404 of December 15, 1976, as amended (the "Brazilian Corporate Law"). In Brazil, a company's bylaws (*estatuto social*) are the principal governing document of a corporation (*sociedade por ações*).

***History of Share Capital***

*Public Offering for the Primary Distribution of Common and Preferred Shares*

At a meeting held on March 25, 2015, our board of directors approved unanimously the realization of a public offering for the primary distribution of common and preferred shares issued by the Company, all registered shares, without par value, free and clear of any liens or encumbrances, including in the form of ADSs, represented by ADRs, held simultaneously in Brazil and abroad, through a capital increase of the Company. The capital increase was approved by the board of directors' meeting held on April 27, 2015, amounting to R$15.8 billion, increasing the Company's share capital from R$37.8 billion to R$53.6 billion through the issuance of 121,711,240 common shares, at an issue price of R$38.47 per unit, and 236,803,588 preferred shares, at an issue price of R$47.00 per unit. Common shares, preferred shares and ADSs issued as a result of this capital increase confer to their holders, as of April 28, 2015, the date of disclosure of the global offering announcement of commencement, the same rights assigned respectively to the holders of common shares, preferred shares and ADSs, currently outstanding, under the Company's bylaws and the Brazilian Corporate Law, fully participating in dividends and other distributions declared from the date of publication of the global offering announcement of commencement. The issue price of R$47.00 per preferred share was determined after the completion of the bookbuilding process, in accordance with article 23, paragraph 1, and article 44 of CVM Instruction No. 400/2003, as amended, or Instruction No. 400, and in accordance with the provisions of article 170, paragraph 1, item III, of the Brazilian Corporate Law. The issue price of R$38.47 per common share was determined based on the price per preferred share determined after the completion of the bookbuilding process, applying a discount of 18.14%, which represents the average price discount trading of the common shares issued by the Company in relation to the trading price of the preferred shares issued by the Company in the three months prior to March 26, 2015.

*Public Offering for the Primary Distribution of Shares*

At a meeting held on April 30, 2015, our board of directors approved a second capital increase in connection with the public offering for the primary distribution of shares, due to the exercise, by the Bank of America Merrill Lynch Banco Múltiplo S.A., of the option of over-allotment of shares that was granted by the Company, in accordance with article 24 of Instruction No. 400, to meet the excess demand verified during the Offering. The Company's share capital was increased in the amount of R$295.3 million, through the issuance of 6,282,660 preferred shares at the issue price of R$47.00 per unit, increasing the share capital of the Company to R$53.9 billion, represented by 503,046,911 common shares and 985,019,821 preferred shares.

*GVTPar Merger and Increase in the Company's Share Capital*

On May 28, 2015, our shareholders approved the merger of shares issued by GVTPar by the Company and its implementation, with the conversion of GVTPar in a wholly owned subsidiary of the Company and the resulting increase in the Company's capital in the amount of R$9.7 billion through the issue of 68,597,306 common shares and 134,320,885 preferred shares, all without par value, increasing the share capital of the Company to R$63.6 billion, as it stands at the date of this report.

------

*Conversion of Our Preferred Shares into Common Shares*

As mentioned above, on October 1, 2020, our shareholders approved, and our preferred shareholders ratified, the conversion of all the preferred shares issued by the Company into common shares, in the proportion of one (1) common share for each one (1) preferred share and its implementation by the Company's officers as well as the relevant changes to the Company's bylaws to reflect the Conversion.

After the concession and the expiration of the term for shareholders to exercise withdrawal rights, we proceeded with the Conversion, and the last trading session for our preferred shares on the B3 and for our ADSs backed by preferred shares on the NYSE was on November 20, 2020. Therefore, as of November 23, 2020, "VIVT3" represents the only ticker symbol for trading of the Company's common shares on the B3, and ADSs backed by our common shares began trading on the NYSE under the ticker symbol "VIV."

The Conversion was undertaken as part of certain improvements to our Corporate Governance Practices, in order to maximize the generation of value to all our shareholders, conferring to them rights set forth under Brazilian Corporate Law, such as the right to vote and the right to tag along, among others.

***Board of Directors***

Under our bylaws, any matters subject to the approval of our Board of Directors can be approved only by the majority of votes of the present members of our Board of Directors. Under our bylaws, our board of directors may only deliberate if a majority of its members currently in office are present at a duly convened meeting and in the event of a tie, the Chairman of the board of directors shall be the tiebreaker.

*Election of Directors*

The members of our Board of Directors are elected at shareholders' meetings for three-year terms. The tenure of the members of the Board of Directors and of the Board of Executive Officers will be conditioned on such members signing the respective instrument of investiture and complying with applicable legal requirements.

*Qualification of Executive Officers and Directors*

Recent changes to the Brazilian Corporate Law have removed the requirement that executive officers must be residents of Brazil. Now, our executive officers and the members of our Board of Directors are not required to be residents of Brazil; however, their tenure is conditioned on the appointment of a representative who resides in Brazil with powers to, for at least three years after the termination of the term of office, to (i) receive service of process in proceedings initiated against such member based on the corporate legislation; and (ii) receive service of process and subpoenas in administrative proceedings initiated by the CVM when holding a management position in a publicly-held company..

*Fiduciary Duties and Conflicts of Interest*

All members of our board of directors owe fiduciary duties to us and all of our shareholders.

Under the Brazilian Corporate Law and the board of directors' internal rules, if one of our directors has a conflict of interest with our Company in connection with any proposed transaction, such director may not vote on any decision of our board of directors regarding such transaction and must disclose the nature and extent of his conflicting interest for inclusion in the minutes of the applicable meeting. The same rules on conflict of interest rules are applicable to executive officers.

Any transaction in which one of our Directors or Executive Officers may have an interest can only be approved on reasonable and fair terms and conditions that are no more favorable than the terms and conditions prevailing in the market or offered by third parties. If any such transaction does not meet this requirement, then the Brazilian Corporate Law provides that the transaction may be held null and void and the interested director or executive officer must return to us any benefits or other advantages that he obtained from, or as result of, such transaction. Under the Brazilian Corporate Law and upon the request of a shareholder who owns at least 1% (as reduced by CVM Resolution No. 70/2022) of our total share capital, our Directors and Executive Officers must disclose to our

------

shareholders at the Annual Shareholders' Meeting certain transactions and circumstances that may give rise to a conflict of interest. In addition, our Company (through the approval of the majority of our share capital) or shareholders who own 1% (as reduced by CVM Resolution No. 70/2022) or more of our share capital may bring an action for civil liability against any Director and/or Executive Officers for any losses caused to us as a result of a conflict of interest.

***Compensation***

Under our bylaws, our common shareholders approve the annual cap for aggregate compensation payable to our Directors, Executive Officers and members of our Fiscal Board. Subject to this approval, our Board of Directors establishes the distribution of such compensation of its members and of our executive officers.

As per Brazilian Corporate Law, the compensation payable to the members of the fiscal board shall not be less than 10% of the compensation of the company's executive officers, not including other benefits listed in paragraph three of article 162 thereof.

*Mandatory Retirement*

Neither the Brazilian Corporate Law nor our bylaws establish a mandatory retirement age for our directors or executive officers.

***Share Capital***

Each of our common shares entitles its holder to one vote at our annual and extraordinary shareholders' meetings. Holders of our common shares are not entitled to any preference in respect of our dividends or other distributions or otherwise in case of our liquidation.

***Shareholders' Meetings***

Under the Brazilian Corporate Law, we must hold an annual shareholders' meeting by April 30 of each year in order to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· approve or reject the financial statements approved by our board of directors, including any recommendation by our Board of Directors for the allocation of net profit and distribution of dividends; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· elect members of our Board of Directors (upon expiration of their three-year terms) and members of our Fiscal Board (every year), subject to the right of minority common shareholders to elect members of our board of directors and our fiscal board.

In addition to the annual shareholders' meetings, holders of our common shares have the power to determine any matters related to changes in our corporate purposes and to pass any resolutions they deem necessary to protect and enhance our development whenever our interests so require, by means of extraordinary shareholders' meetings.

We convene our shareholders' meetings, including our annual shareholders' meeting, by publishing a notice in a Brazilian major newspaper. On the first call of a shareholders' meeting, the notice must be published no fewer than three (3) times, beginning, the first notice, at least twenty one (21) calendar days prior to the scheduled meeting date. On the second call of a shareholders' meeting, the notice must be published no fewer than three (3) times, beginning at least eight (8) calendar days prior to the scheduled meeting date. In accordance with our bylaws, for meetings involving deliberations described under article 136 of the Brazilian Corporate Law, the notice must be published at least thirty (30) calendar days prior to the scheduled meeting date and on the second call at least ten (10) calendar days prior to the scheduled meeting date. As recommended by the CVM, for annual shareholders' meetings, we convene our shareholders' meeting thirty (30) calendar days prior to the scheduled meeting date. The notice must contain the meeting's place, date, time, agenda and, in the case of a proposed amendment to our bylaws, a description of the subject matter of the proposed amendment.

Our Board of Directors may convene shareholders' meetings. Under the Brazilian Corporate Law, shareholders' meetings also may be convened by our shareholders as follows:

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· by any of our shareholders if, under certain circumstances set forth in the Brazilian Corporate Law, our Directors do not convene a shareholders' meeting required by law within sixty (60) days; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· by shareholders holding at least 1% (as reduced by CVM Resolution No. 70/2022) of our total share capital if, after a period of eight (8) days, our Directors fail to call a shareholders' meeting that has been requested by such shareholders by means of a duly reasoned request that indicates the subject matter.

In addition, our Fiscal Board may convene an ordinary shareholders' meeting if our Board of Directors does not convene an annual shareholders' meeting within thirty (30) days or an extraordinary shareholders' meeting at any other time to consider any urgent and serious matters.

Each shareholders' meeting is presided over by the president of the Board of Directors, who is responsible for choosing a secretary of the meeting among those present at the meeting. In case of absence of the president of the Board of Directors at the shareholders' meeting, the shareholders may choose, among those present, the president and the secretary of the meeting. A shareholder may be represented at a shareholders' meeting by an attorney-in-fact appointed by the shareholder less than one (1) year before the meeting. The attorney-in-fact must be a shareholder, a member of our Board of Directors, a member of our Board of Executive Officers, a lawyer or a financial institution, and the representation of the condominium members shall be made by the manager of the investment fund. The power of attorney appointing the attorney-in-fact must comply with certain formalities set forth under Brazilian law. To be admitted to a shareholders' meeting, a person must produce proof of his or her shareholder status and/or a valid power of attorney (if the shareholder is to be represented by an attorney-in-fact), together with any other requirement provided for in the call notice.

In order to convene a shareholders' meeting, shareholders representing at least 25% (except when the agenda sets forth a matter that requires a higher quorum) of our issued voting share capital must be present on the first call. However, shareholders representing at least two-thirds of our issued voting share capital must be present at a shareholders' meeting called to amend our bylaws. If a quorum is not met, our Board of Directors may issue a second call by publishing a notice as described above at least eight (8) calendar days prior to the scheduled meeting. Except as otherwise provided by law, the quorum requirements do not apply to a meeting held on the second call, and the shareholders' meetings may be convened with the presence of shareholders representing any number of shares (subject to the voting requirements for certain matters described below).

***Remote Voting***

Pursuant to the CVM Resolution No. 81/2022, as amended, the system of Remote Voting is required to be adopted by Brazilian companies for: (i) an Ordinary General Shareholders' Meeting; (ii) whenever an Extraordinary General Shareholders' Meeting is called and occurs on the same date as an Ordinary General Shareholders' Meeting; and (iii) whenever a Shareholders' Meeting is called to elect the members of the fiscal board or of the board of directors, due to the requirements set forth in article 26, paragraph 1, item II of CVM Resolution No. 81/2022 (Remote Voting can be adopted in other situations, at the Company's choice). This system aims to facilitate the participation of the Company's shareholders in its meetings. This resolution provides for the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the creation of a Remote Voting Ballot (*Boletim de Voto a Distância*) through which the shareholders may exercise their right to vote prior to the date in which the shareholders' meeting is held;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the possibility to include in the Remote Voting Ballot a list of candidates and submit minority shareholders' proposals, for deliberation at the shareholders' meeting, upon satisfaction of certain criteria;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the deadlines, procedures and means of transmitting the Remote Voting Bulletin; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the possibility of holding shareholders' meeting by fully digital means (in which case shareholders may only participate virtually) or partially digital means (in which case shareholders may either participate virtually or attend the meeting in person at the Company's headquarters).

In addition, listed companies are required to adopt certain measures regarding the voting process, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· informing the market of the adoption of the cumulative voting process in shareholders' meetings immediately upon receipt of the first valid requirement; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· disclosing voting maps, as well as any voting statement presented by a shareholder at a meeting;

In accordance with the provisions of applicable laws and regulations, the Company has adopted the Remote Voting System since its Annual Shareholders' Meeting held on April 26, 2017.

We do not have an electronic system for receiving Remote Voting Ballot or remote participation ballots. Exceptionally, we may hold meetings partially or exclusively through a digital format, in accordance with CVM Resolution No. 81/2022. Specific instructions regarding remote voting in shareholders' meetings, which we may decide to hold partially or exclusively through a digital format, will be disclosed in the relevant shareholders' meeting manual, in addition to other channels that we may deem appropriate.

***Voting Rights***

Under the Brazilian Corporate Law and our bylaws, each of our common shares entitles its holder to one vote at our shareholders' meetings. There are no limitations under the Brazilian Corporate Law or our bylaws on the right of non-Brazilian residents or nationals to own shares or vote according to those shares, other than the restrictions applicable to all shareholders.

*Voting Rights of Common Shares*

Except as otherwise provided by law, resolutions of a shareholders' meeting are passed by a simple majority vote of the holders of our common shares present or represented at the meeting, without taking abstentions into account. Under the Brazilian Corporate Law, the approval of shareholders representing at least half of our voting shares, if a higher quorum is not required by our bylaws, is required for the types of action described below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· creating preferred shares or disproportionately increasing an existing class of our preferred shares relative to the other classes of our preferred shares, other than to the extent permitted by our bylaws;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· changing a preference, privilege and condition of redemption or amortization of any class of the company`s preferred shares or creating a new class of shares that is more privileged;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· reducing the mandatory dividend;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· merging or consolidating the company with another company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· participating in a centralized group of companies (grupo de sociedades) as defined under the Brazilian Corporate Law and subject to the conditions set forth in the Brazilian Corporate Law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· acquisition of all the company's shares by another company, known as an "incorporação de ações" under the Brazilian Corporate Law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· changing the company's corporate purpose;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· canceling any ongoing liquidation of the company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· creation of participation certificates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· spinning-off of all or any part of the company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· dissolution of the company.

As per Brazilian Corporate Law, the decisions on the transformation of the company into another form of business entity require the unanimous approval of our shareholders, unless provided for in the company by-laws.

Our Company is required to give effect to shareholders agreements that contain provisions regarding the purchase or sale of our shares, preemptive rights to acquire our shares, the exercise of the right to vote or the power to control our Company, if these agreements are filed with our headquarters. Brazilian Corporate Law requires the president of any Shareholder's or Board of Directors meeting to disregard any vote taken by any of the parties to said agreement that have been duly filed with our Company in violation of the provisions of any such agreement. In

------

the event that a shareholder that is party to a shareholders agreement (or a director appointed by such shareholder) is absent from any shareholders' or Board of Directors' meeting or abstains from voting, the other party or parties to that shareholders agreement have the right to vote the shares of the absent or abstaining shareholder (or on behalf of the absent director) in compliance with that shareholders agreement.

For the effective implementation of the Conversion, a voting agreement was executed on October 1, 2020 by and among the shareholders Telefónica S.A., Telefónica LATAM, SP Telecom, and, as intervening and consenting party, the Company, in order to comply with the provisions of ANATEL regulations. This voting agreement was filed and made available at our Company headquarters, as determined under article 118 of Brazilian Corporate Law (the "Voting Agreement").

However, on October 31, 2022, the Company informed the market and its shareholders that the Voting Agreement lost its purpose and effectiveness as a result of the liquidation and extinction of SP Telecom that took place on that date, given that its purpose consisted of maintaining the exercise of direct control power of the Company by SP Telecom.

The shares issued by the Company and held by SP Telecom. ("Shares") were delivered to its partners Telefónica S.A. and Telefónica LATAM, in the proportion of their respective participation in the social capital of SP Telecom, within the scope of the sharing of shareholders' equity.

The Company informed the market that the liquidation of SP Telecom, the consequent termination of the Voting Agreement and the aforementioned delivery of SP Telecom's shares did not result in a change in the composition of the Company's control (which was already indirectly held jointly by Telefónica S.A., Telefónica LATAM and SP Telecom, all companies under common control with Telefónica S.A.), its administrative structure or its regular operation*.*

Under the Brazilian Corporate Law, neither our bylaws nor actions taken at a shareholders' meeting may deprive any of our shareholders of certain specific rights, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the right to participate in the distribution of our profits;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the right to participate in any remaining residual assets in the event of our liquidation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the right to supervise the management of our corporate business subject to the conditions set forth in the Brazilian Corporate Law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· preemptive rights in the event of an issuance of our shares, debentures convertible into our shares or subscription bonuses, except with respect to a public offering of our securities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the right to withdraw from our Company subject to the conditions set forth in the Brazilian Corporate Law.

*Voting Rights of Minority Shareholders*

Shareholders holding shares representing not less than 5% of our voting shares at our shareholders' meeting have the right to request that we adopt, even if not foreseen in ou bylaws, a cumulative voting procedure to elect the members of the Board of Directors. This procedure must be requested by the required number of shareholders at least 48 hours prior to a shareholders' meeting.

Under the Brazilian Corporate Law, shareholders that are not controlling shareholders, but that together hold common shares representing at least 15% of our voting capital have the right to appoint one member and their alternate to our Board of Directors at our shareholders' meeting. However, CVM has already issued several decisions determining that, in cases where the company has issued only shares with voting rights, such as the Company, the percentage to be considered for the appointment of the member of the Board of Directors by the non-controlling shareholders shall be reduced to 10% of the total of common shares.

In the event that minority holders of common shares elect a director and the cumulative voting procedures described above is also used, our controlling shareholders always retain the right to elect at least one member more than the number of members elected by the other shareholders, regardless of the total number of members of our Board of Directors.

------

The shareholders seeking to exercise these minority rights (except for the cumulative voting procedure) must prove that they have held their shares for no less than three months preceding the shareholders' meeting at which the director will be appointed. Brazilian Corporate Law provides that any directors appointed by the non-controlling shareholders have the right to veto for cause the selection of our independent registered public accounting firm.

In accordance with the Brazilian Corporate Law, minority shareholders are entitled to elect one member and an alternate to our Fiscal Board in a separate election as long as they jointly represent 10% or more of the voting shares. The other shareholders with the right to vote may elect the remaining members and alternates, who, in any event, must outnumber the directors and alternates elected by minority common shareholders.

Under the Brazilian Corporate Law, the following actions require the previous approval of or the ratification by the majority of issued and outstanding shares of the affected class within one year from the shareholders' meeting at which the common shareholders approve the action:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the creation of preferred shares or a disproportionate increase of an existing class of preferred shares relative to the other classes of preferred shares, other than to the extent permitted by our bylaws;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· a change of a priority, preference, right, privilege or condition of redemption or amortization of any class of preferred shares; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the creation of a new class of preferred shares that has a priority, preference, right, condition or redemption or amortization superior to an existing class of preferred shares.

This meeting would be called by publication of a notice in two Brazilian newspapers for three days, at least 30 days before the meeting, in accordance with our bylaws.

***Liquidation***

We may be liquidated in accordance with the provisions of Brazilian law. In the event of our extrajudicial liquidation, a shareholders' meeting will determine the manner of our liquidation, appoint our liquidator and our Fiscal Board that will function during the liquidation period.

***Preemptive Rights***

Each shareholder has a general preemptive right to subscribe for shares of the same class in any capital increase, in an amount sufficient to keep the same proportional participation of such shareholder in the total capital of the corporation. A minimum period of thirty (30) days following the publication of the capital increase notice shall be observed by the corporation for the exercise of the preemptive right by the shareholder. The right of participation in capital increases is assignable under Brazilian Corporate Law. In the event of a capital increase that would maintain or increase the proportion of capital represented by common shares, holders of ADSs, or of common shares, would have the preemptive right to subscribe only to our newly issued common shares. In the event of a capital increase that would reduce the proportion of capital represented by common shares, holders of ADSs, or of common shares, would have the preemptive right to subscribe to our newly issued common shares in proportion to their shareholdings and to our newly issued common shares only to the extent necessary to prevent dilution of their interest.

However, holders of our ADSs may not be able to exercise the preemptive rights relating to our common shares underlying their ADSs unless a registration statement under the Securities Act is effective with respect to those rights or an exemption from the registration requirements of the Securities Act is available. We are not obligated to file a registration statement with respect to the shares relating to these preemptive rights or to take any other action to make preemptive rights available to holders of our ADSs, and we may not file any such registration statement.

In addition, a publicly held company whose bylaws allow for capital increases may provide for the issuance of stock, debentures convertible into stock or subscription bonuses without granting any preemptive rights to prior shareholders or by decreasing the term for the shareholders to exercise their preemptive rights, as long as the placement of such securities is made:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· upon a sale on a stock exchange or public subscription;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· through an exchange of shares in a public offering, with the purpose of acquiring control of another company as specified in the Brazilian Corporate Law; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· for the use of certain tax incentives but only when such placement is made without granting preemptive rights.

***Redemption, Amortization, Tender Offers and Rights of Withdrawal***

Our bylaws or our shareholders at a shareholders' meeting may authorize us to use our profits or reserves to redeem or amortize our shares in accordance with conditions and procedures established for such redemption or amortization. The Brazilian Corporate Law defines "redemption" (*resgate de ações*) as the payment of the value of the shares in order to permanently remove such shares from circulation, with or without a corresponding reduction of our share capital. However, if the same share capital is maintained, the Company shall attribute a new par value for the remaining shares. The Brazilian Corporate Law defines "amortization" (*amortização*) as the distribution to the shareholders, without a corresponding capital reduction, of amounts that they would otherwise receive if we were liquidated. If an amortization distribution has been paid prior to our liquidation, then upon our liquidation, the shareholders who did not receive an amortization distribution will have a preference equal to the amount of the amortization distribution in the distribution of our capital.

The Brazilian Corporate Law authorizes us to redeem shares not held by our controlling shareholders, if, after a tender offer effected as a consequence of a delisting of the Company before the CVM, less than 5% of our outstanding shares remains publicly-held. The redemption price in such case would be the same price paid for our shares in such tender offer.

The Brazilian Corporate Law also require the acquirer of control (in case of a change of control) or the controller (in case of delisting or a substantial reduction in liquidity of our shares) to make a tender offer for the acquisition of the shares held by minority shareholders under certain circumstances described below under "—Mandatory Tender Offers." The shareholder can also withdraw its capital from our Company under certain circumstances described below under "—Rights of Withdrawal."

*Mandatory Tender Offers*

The Brazilian Corporate Law requires the launching of a tender offer at a purchase price equal to the fair value for all outstanding shares in order to cancel (or to convert) the registration of our company as a publicly held company or in case of a substantial reduction in the liquidity of our shares as a result of purchases by our controlling shareholders. If our controlling shareholders enter into a transaction which results in a change of control of our company, the controlling shareholders must include in the documentation of the transaction an obligation of the acquirer to launch a tender offer for the purchase of all our common shares for, at least, 80% of the price per share paid to the controlling shareholders. The tender offer must be submitted to the CVM within 30 days from the date of execution of the definitive documents of sale of the shares.

*Rights of Withdrawal*

The Brazilian Corporate Law provides that, in certain limited circumstances, a dissenting shareholder may withdraw its equity interest from our company and be reimbursed by us for the value of our common shares that it then holds.

This right of withdrawal may be exercised by dissenting shareholders in the event that the holders of shares with voting rights authorize:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) creating preferred shares or disproportionately increasing any existing class of preferred shares relative to the other classes of preferred shares, other than to the extent permitted by our bylaws;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) changing a priority, preference, right, privilege or condition of redemption or amortization of any class of preferred shares or creating a new class of shares that is more privileged;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) reducing the mandatory dividend;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) a change in our corporate purpose;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) merging or consolidating our Company, with another company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) the acquisition of all of our shares by another company, known as an "incorporação de ações" under the Brazilian Corporate Law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) participating in a centralized group of companies (grupo de sociedades) as defined under the Brazilian Corporate Law and subject to the conditions set forth in the Brazilian Corporate Law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) spinning-off of all or any part of our Company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix) the inclusion of an arbitration clause in our bylaws.

In addition, we note that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· in items (i) and (ii), only the holders of shares of the affected type or class will be entitled to redemption;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· in items (v) to (vii), the holders of shares of a type or class with liquidity and dispersion (as defined in CVM Resolution 78/2022) in the market will not have the right to redemption considering the conditions set forth in the Brazilian Corporate Law; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· in item (viii), the dissenting shareholders shall only have a right of redemption if the spinning off implies in: (1) a change in the corporate purpose (except if the spun-off assets revert to a company whose main purpose is the same as ours), (2) a reduction of the mandatory dividend, or (3) participation in a group of companies.

Dissenting shareholders are also entitled to withdraw in the event that the entity resulting from a merger or spin-off does not have its shares listed in an exchange or traded in the secondary market within one hundred and twenty (120) days from the shareholders' meeting that approved the relevant merger or spin-off.

Notwithstanding the above, in the event that we are consolidated or merged with another company, become part of a centralized group of companies, or acquire the control of another company for a price in excess of certain limits imposed by the Brazilian Corporate Law, holders of any type or class of our shares or the shares of the resulting entity that have minimal market liquidity and are dispersed among a sufficient number of shareholders will not have the right to withdraw. For this purpose, shares that are part of general indices representative of portfolios of securities traded in Brazil (as defined by CVM Resolution 78/2022) or abroad are considered liquid, and sufficient dispersion will exist if the controlling shareholder, the parent company or other companies under its control hold less than half of the total number of outstanding shares of that type or class.

Only shareholders who own shares on the date of publication of the first notice convening the relevant shareholders' meeting or the press release concerning the relevant transaction is published, whichever is earlier, will be entitled to withdrawal rights.

The redemption of shares arising out of the exercise of any withdrawal rights would be made at the book value per share, determined on the basis of our most recent audited balance sheet approved by our shareholders. If the shareholders' meeting approving the action that gave rise to withdrawal rights occurred more than sixty (60) days after the date of the most recent approved audited balance sheet, a shareholder may demand that its shares be valued on the basis of a balance sheet prepared specifically for this purpose. In this case the company shall pay immediately 80% of the redemption value calculated based on the last balance sheet and, having drawn up the necessary balance sheet, will pay the remaining amount within one hundred and twenty (120) days from the date of the resolution of the shareholders' meeting.

The right of withdrawal lapses thirty (30) days after the date of publication of the minutes of the shareholders' meeting that approved the action that gave rise to withdrawal rights. Within ten days following the expiration of the term to exercise the withdrawal rights mentioned above, the company may call a Shareholders' Meeting to confirm or reconsider any resolution giving rise to withdrawal if we believe that the withdrawal of shares of dissenting shareholders would jeopardize its financial stability.

------

***Liability of Our Shareholders for Further Capital Calls***

Neither Brazilian law nor our bylaws require any capital calls. Our shareholders' liability for capital calls is limited to the payment of the issue price of any shares subscribed or acquired.

***Inspection of Corporate Records***

Shareholders that own 1% (as reduced by CVM Resolution 70/2022) or more of our outstanding share capital have the right to inspect our corporate records, including shareholders' lists, corporate minutes, financial records and other documents of our company, if (1) any acts contrary to Brazilian law or the company's bylaws have been committed, or (2) there are grounds to suspect that there are material irregularities in our company. However, in either case, the shareholder that desires to inspect our corporate records must obtain a court order authorizing the inspection.

***Disclosures of Share Ownership***

Brazilian regulations require that (1) each of our controlling shareholders, directly or indirectly, (2) shareholders who have elected members of our Board of Directors or Fiscal Board, and (3) any person or group of persons representing a person that has directly or indirectly acquired or sold a material interest in our shares of any type and class disclose its or their share ownership or divestment to us, and we are responsible for transmitting such information to the CVM and the market. In addition, if a share acquisition results in, or is made with the intention of, change of control or company's management structure, as well as acquisitions that cause the obligation of performing a tender offer, the persons acquiring such number of shares are required to publish a statement containing certain required information about such acquisition in the same channels the Company typically uses.

CVM defines a "material interest" deal as any increase or decrease in share ownership of any class resulting in a change in the *ownership levels* of our shareholders. The ownership levels are set in 5% increments (for example, an acquisition where the total ownership of a shareholder jumps from 9% to 11% should be reported since it made the ownership surpass the 10% level). Ownership levels are calculated adding direct and indirect ownership and derivatives based upon our shares.

Our controlling shareholders, shareholders that appoint members of our Board of Directors or Fiscal Board and members of our Board of Directors, Board of Executive Officers or Fiscal Board must file a statement reporting any change in their holdings of our shares, or of any family member or person included as dependent in their income tax return, or of our controlling shareholders (only if they are considered public companies), with the CVM and the Brazilian stock exchanges on which our securities are traded.

***Form and Transfer***

Our common shares are in book-entry form, registered in the name of each shareholder or its nominee. The transfer of our shares is governed by article 35 of the Brazilian Corporate Law, which provides that a transfer of shares is effected by our transfer agent by an entry made by the transfer agent in its books, upon presentation of valid written share transfer instructions to us by a transferor or its representative. When common shares are acquired or sold on a Brazilian stock exchange, their transfer is effected on the records of our transfer agent by a representative of a brokerage firm or the stock exchange's clearing system. The transfer agent also performs all the services of safe-keeping of our shares. Transfers of our shares by a non-Brazilian investor are made in the same manner and are executed on the investor's behalf by the investor's local agent. If the original investment was registered with the Central Bank pursuant to foreign investment regulations, the non-Brazilian investor is also required to amend, if necessary, through its local agent, the electronic certificate of registration to reflect the new ownership.

The B3 operates a central clearing system. A holder of our shares may choose, at its discretion, to participate in this system, and all shares that such shareholder elects to be put into the clearing system are deposited in custody with the clearing and settlement chamber of the B3 (through a Brazilian institution that is duly authorized to operate by the Central Bank and maintains a clearing account with the clearing and settlement chamber of the B3). Shares subject to the custody of the clearing and settlement chamber of the B3 are noted as such in our registry of shareholders. Each participating shareholder will, in turn, be registered in the register of the clearing and settlement chamber of the B3 and will be treated in the same manner as shareholders registered in our books.

------

**Dividends**

Brazilian Corporate Law also states that declared dividends must be paid until the end of the fiscal year in which it was declared. Under article 9 of Law 9,249/95 and our bylaws, we also may pay interest attributable to shareholders' equity as an alternative form of dividends upon approval of our board of directors

***Payment of Dividends and Interest on Shareholders' Equity***

We may pay the mandatory distributable amount as dividends or as interest attributable to shareholders' equity, which is similar to a dividend but is deductible in calculating our income tax obligations.

The common shares underlying our ADSs are held in Brazil by the depositary, which has registered with the Central Bank as the registered owner of our common shares. Payments of cash dividends and distributions, if any, will be made in Brazilian currency to the depositary. The depositary will then convert such proceeds into U.S. dollars and will cause such U.S. dollars to be distributed to holders of our ADSs. As with other types of remittances from Brazil, the Brazilian government may impose temporary restrictions on remittances to foreign investors of the proceeds of their investments in Brazil, as it did for approximately six months in 1989 and early 1999, and on the conversion of Brazilian currency into foreign currencies, which could hinder or prevent the depositary from converting dividends into U.S. dollars and remitting these U.S. dollars abroad.

In addition, remittances are subject to a Brazilian financial transactions tax, which as of the date of this annual report zero, but may be subject to change.

For information about taxation on profits, dividends and interest on shareholders' equity, see "—E. Taxation—Brazilian Tax Considerations—Taxation of Dividends."

*Dividends*

We are required by the Brazilian Corporate Law and by our bylaws to hold an annual shareholders' meeting until April 30 of each year. At our annual shareholders' meeting, our common shareholders may vote to declare an annual dividend. Our payment of annual dividends is based on our audited financial statements prepared for our preceding fiscal year.

Any holder of record of shares at the time that a dividend is declared is entitled to receive dividends. Under the Brazilian Corporate Law, we are generally required to pay dividends within 60 days after declaring them, unless the shareholders' resolution establishes another payment date, which, in any case, must occur prior to the end of the fiscal year in which the dividends were declared.

Our Board of Directors may declare interim dividends based on (i) the accrued profits recorded in our semiannual financial statements; (ii) the accrued profits recorded in our quarterly financial statements or in our financial statements for shorter periods, provided that the total amount of dividends paid up every six months does not exceed the total amount within the capital reserve determined pursuant to article 182 of the Brazilian Corporate Law; and (iii) the amount recorded in the profit and loss account or profit reserve account in our last annual or semiannual financial statements.

All the interim dividends that are distributed shall be considered as part of the mandatory dividends that shall be paid by us.

*Interest on Shareholders' Equity*

Brazilian corporations may make payments to shareholders characterized as interest on shareholders' equity as an alternative form of making dividend distributions. Amounts paid as interest on shareholders' equity (net of applicable withholding tax, as described below) may be deducted from the minimum dividends we are obligated to distribute to our shareholders in accordance with our bylaws and Brazilian Corporate Law. The rate of interest may not be higher than the federal government's TJLP, as determined by the Central Bank from time to time (7.5% per annum for 2016 and for the first quarter of 2017, 7.0% for the remaining quarters of 2017, 6.75%, 6.6%, 6.56% and 6.98% for the four quarters of 2018, and 7.03%, 6.26%, 5.95% and 5.57% for the four quarters of 2019, and 5.09%, 4.94%, 4.91% and 4.55% for the four quarters of 2020, and 4.39%, 4.61%, 4.88% and 5.32% for the four quarters of 2021, and 6,08%, 6,82%, 7,01% and 7,20% for the four quarters of 2022), applied over specific net equity accounts.

------

The total amount distributed as interest on shareholders' equity may not exceed the greater of (i) 50% of net income (before taking the distribution and any deductions for income taxes into account) for the year with respect to which the payment is made and (ii) 50% of retained earnings for the year before that in which the payment is made. Payments of interest on shareholders' equity are decided by the shareholders on the basis of recommendations of our Board of Directors.

Distributions of interest on shareholders' equity paid to Brazilian and non-Brazilian holders of common shares, including payments to the depositary in respect of common shares underlying ADSs, are deductible by us for Brazilian corporate income tax purposes. These payments to U.S. holders or other non-Brazilian holders are subject to Brazilian withholding tax at the rate of 15%. If the recipient of the payment is domiciled in a Tax Haven Jurisdiction, as defined by Brazilian law, the rate will be 25%.

*Time Limits for Claiming Dividends*

Our shareholders have three (3) years to claim dividend distributions made with respect to their shares, as from the date that we distribute the dividends to our shareholders, after which any unclaimed dividend distributions legally revert to us. We are not required to adjust the amount of any distributions for inflation that occurs during the period from the date of declaration to the payment date.

**AMERICAN DEPOSITARY SHARES**

**Item 12. Other securities**

Disclosures under Items 12.A, 12.B, and 12.C are not applicable.

**12. D.1 Depositary**

Citibank, N.A. acts as the depositary for the American Depositary Shares. Citibank's depositary offices are located at 388 Greenwich Street, New York, New York 10013, U.S.A.

**12. D.2 Provisions**

American Depositary Shares are frequently referred to as "ADSs" and represent ownership interests in securities that are on deposit with the depositary. ADSs may be evidenced by certificates that are commonly known as "American Depositary Receipts" or "ADRs." In the United States, the common shares trade in the form of ADRs, each representing one common share, issued by Citibank N.A., as depositary, pursuant to a Deposit Agreement, among us, the depositary and the registered holders and beneficial owners from time to time of ADRs. The depositary typically appoints a custodian to safekeep the securities on deposit. In this case, the custodian is Citibank DTVM S.A., located at Avenida Paulista 1,111, São Paulo, SP, 01311-920, Brazil.

As of December 31, 2022, there were a total of 143 ADR holders of record and 121,913,737 ADSs outstanding, representing 121,913,737 common shares or 7.3% of outstanding common shares.

We are providing you with a summary description of the material terms of the ADSs and of your material rights as an owner of ADSs. We urge you to review the Deposit Agreement in its entirety, which is an exhibit to our registration statement on Form F-6 filed with the SEC on October 16, 2020, and which exhibit is incorporated by reference as exhibit to this annual report on Form 20-F.

Each ADS represents the right to receive, and exercise beneficial ownership interests in, one of our common shares on deposit with the custodian. An ADS also represents the right to receive, and exercise beneficial ownership interests in, any other securities, cash or property received by the depositary or the custodian on behalf of the owner of the ADS but that has not been distributed to the owners of ADSs because of legal restrictions or practical considerations.

If you become an owner of ADSs, you will become a party to the deposit agreement and therefore will be bound to its terms and to the terms of any ADR that evidences your ADSs. The deposit agreement and the ADR specify our rights and obligations as well as your rights and obligations as owner of ADSs and those of the depositary. As an ADS holder you appoint the depositary to act on your behalf in certain circumstances. The deposit agreement, the

------

ADSs, and the ADRs are governed by New York law. However, our obligations to the holders of common shares will continue to be governed by the laws of Brazil, which may be different from the laws in the United States.

In addition, applicable laws and regulations may require you to satisfy reporting requirements and obtain regulatory approvals in certain circumstances. You are solely responsible for complying with such reporting requirements and obtaining such approvals.

Neither the depositary, the custodian, us or any of their or our respective agents or affiliates will be required to take any actions whatsoever on behalf of you to satisfy such reporting requirements or obtain such regulatory approvals under applicable laws and regulations.

The manner in which you own the ADSs (*e.g*., in a brokerage account vs. as registered holder, or as holder of certificated vs. uncertificated ADSs) may affect your rights and obligations, and the manner in which, and extent to which, the depositary bank's services are made available to you. As an owner of ADSs, you may hold your ADSs either directly in the form of certificated ADSs evidenced by an ADR registered in your name, indirectly through a brokerage or safekeeping account, or directly through an account established by the depositary in your name reflecting the registration of uncertificated ADSs directly on the books of the depositary (commonly referred to as the "direct registration system" or "DRS").

The direct registration system reflects the uncertificated (book-entry) registration of ownership of ADSs by the depositary. Under the direct registration system, ownership of ADSs is evidenced by periodic statements issued by the depositary to the holders of the ADSs. The direct registration system includes automated transfers between the depositary and The Depository Trust Company, or "DTC," the central book-entry clearing and settlement system for equity securities in the United States. If you decide to hold your ADSs through your brokerage or safekeeping account, you must rely on the procedures of your broker or bank to assert your rights as an ADS owner. Banks and brokers typically hold securities such as the ADSs through clearing and settlement systems such as DTC. The procedures of such clearing and settlement systems may limit your ability to exercise your rights as an owner of ADSs. Please consult with your broker or bank if you have any questions concerning these limitations and procedures. All ADSs held through DTC will be registered in the name of a nominee of DTC. This summary description assumes you have opted to own the ADSs directly by means of an ADS registered in your name and, as such, we will refer to you as the "holder." Only persons in whose name ADRs are registered on the books of the depositary will be treated by us and the depositary as ADR holders. When we refer to "you," we assume the reader owns ADSs and will own ADSs at the relevant time.

The registration of the common shares in the name of the depositary bank or the custodian shall, to the maximum extent permitted by applicable law, vest in the depositary bank or the custodian the record ownership in the applicable common shares with the beneficial ownership rights and interests in such common shares being at all times vested with the beneficial owners of the ADSs representing the common shares. The depositary bank or the custodian shall at all times be entitled to exercise the beneficial ownership rights in all deposited property, in each case only on behalf of the holders and beneficial owners of the ADSs representing the deposited property.

**Dividends and Distributions**

As a holder, you generally have the right to receive the distributions we make on the common shares deposited with the custodian. Your receipt of these distributions may be limited, however, by practical considerations and legal limitations. Holders will receive such distributions under the terms of the deposit agreement in proportion to the number of underlying common shares that your ADSs represent as of a specified record date.

*Distributions of Cash*

Whenever we intend to make a distribution of a cash dividend or other cash distribution in respect of ADSs, we will give timely notice thereof to the depositary specifying, among other things, the record date applicable for determining the holders of ADSs entitled to receive such distribution. Upon the timely receipt of such notice, the depositary will establish the ADS record date. Upon confirmation of the receipt of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· any cash dividend or other cash distribution on the common shares held in respect of the ADSs, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· proceeds from the sale of any deposited property held in respect of the ADSs under the terms hereof, the depositary will

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) if any amounts are received in a foreign currency, promptly convert or cause to be converted such cash dividend, distribution or proceeds into U.S. dollars,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) if applicable and unless previously established, establish the ADS record date, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) distribute promptly the amount thus received (net of (a) the applicable fees and charges set forth in the fee schedule set forth below under "—Fees and Charges" and (b) applicable taxes withheld) to the holders entitled thereto as of the ADS record date in proportion to the number of ADSs held as of the ADS record date.

The depositary will distribute only such amount, however, as can be distributed without attributing to any holder a fraction of one cent, and any balance not so distributed will be held by the depositary (without liability for interest thereon) and will be added to and become part of the next sum received by the depositary for distribution to holders of ADSs outstanding at the time of the next distribution. If we withhold, or the custodian or the depositary is required to withhold and does withhold, from any cash dividend or other cash distribution in respect of the common shares held in respect of the ADSs, or from any cash proceeds from the sales of deposited property, an amount on account of taxes, duties or other governmental charges, the amount distributed to holders on the ADSs will be reduced accordingly. Such withheld amounts will be forwarded by us, the custodian or the depositary to the relevant governmental authority. Evidence of payment thereof by us will be forwarded by us to the depositary upon request. The depositary will hold any cash amounts it is unable to distribute in a non-interest bearing account for the benefit of the applicable holders and beneficial owners of ADSs until the distribution can be effected or the funds that the depositary holds must be escheated as unclaimed property in accordance with the laws of the relevant states of the United States. Notwithstanding anything contained in the deposit agreement to the contrary, in the event we fail to give the depositary timely notice of the proposed distribution under this paragraph, the depositary will use commercially reasonable efforts to perform the actions contemplated in this paragraph, and we and you acknowledge that the depositary shall have no liability for its failure to perform the actions contemplated in this paragraph where such notice has not been so timely given, other than for willful misconduct or its failure to use commercially reasonable efforts, as provided in this paragraph.

*Distributions of Shares*

Whenever we intend to make a distribution that consists of a dividend in, or free distribution of, shares, we will give timely notice thereof to the depositary specifying, among other things, the record date applicable to holders of ADSs entitled to receive such distribution. Upon the timely receipt of such notice from us, the depositary will establish the ADS record date. Upon receipt of confirmation from the custodian of the receipt of the shares so distributed by us, the depositary will either:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) distribute to the holders as of the ADS record date in proportion to the number of ADSs held as of the ADS record date, additional ADSs, which represent in the aggregate the number of shares received as such dividend, or free distribution, subject to the other terms of the deposit agreement (including, without limitation, (a) the applicable fees and charges of, and expenses incurred by, the depositary and (b) taxes), or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) if additional ADSs are not so distributed, take all actions necessary so that each ADS issued and outstanding after the ADS record date will, to the extent permissible by law, thenceforth also represent rights and interests in the additional integral number of shares distributed upon the common shares held in respect of such ADSs (net of (a) the applicable fees and charges of, and expenses incurred by, the depositary and (b) taxes).

In lieu of delivering fractional ADSs, the depositary will sell the number of shares or ADSs, as the case may be, represented by the aggregate of such fractions and distribute the net proceeds. In the event that the depositary determines that any distribution in property (including shares) is subject to any tax or other governmental charges which the depositary is obligated to withhold, or, if we in the fulfillment of our obligation, have furnished an opinion of U.S. counsel determining that shares must be registered under the Securities Act or other laws in order to be distributed to holders (and no such registration statement has been declared effective), the depositary may dispose of all or a portion of such property (including shares and rights to subscribe therefor) in such amounts and in such manner, including by public or private sale, as the depositary deems necessary and practicable, and the depositary will distribute the net proceeds of any such sale (after deduction of (a) taxes and (b) fees and charges of, and expenses incurred by, the depositary) to holders entitled thereto upon the terms described in the deposit agreement.

------

The depositary will hold and/or distribute any unsold balance of such property in accordance with the provisions of the deposit agreement. Notwithstanding anything contained in the deposit agreement to the contrary, in the event we fail to give the depositary timely notice of the proposed distribution under this paragraph, the depositary will use commercially reasonable efforts to perform the actions contemplated in this paragraph, and we and you acknowledge that the depositary shall have no liability for its failure to perform the actions contemplated in this paragraph where such notice has not been so timely given, other than for willful misconduct or its failure to use commercially reasonable efforts, as provided in this paragraph.

*Distributions of Rights*

Whenever we intend to distribute rights to purchase additional common shares, the depositary will make such rights available to holders of ADSs only if

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) we timely provide evidence satisfactory to the depositary that it may lawfully distribute such rights,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) we timely indicate that we wish such rights to be made available to holders of ADSs, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the depositary determines that making such rights so available is lawful and reasonably practicable.

If any of clauses (i) through (iii) of the preceding sentence are not satisfied, the depositary may sell such rights, if practicable, and distribute the net proceeds in the same way it distributes cash, or if the sale of such rights cannot practicably be accomplished by reason of the non-transferability of the rights, limited markets therefor, their short duration or otherwise, the depositary may allow such rights to lapse, in which case you will receive nothing.

You may have to pay fees, expenses, taxes and other governmental charges to subscribe for the new ADSs upon the exercise of your rights.

*Elective Distributions*

Whenever we intend to distribute a dividend payable at the election of shareholders either in cash or in additional shares, we will give prior notice thereof to the depositary bank and will indicate whether we wish the elective distribution to be made available to you. In such case, we will assist the depositary bank in determining whether such distribution is lawful and reasonably practicable.

The depositary bank will make the election available to you only if it is reasonably practicable and if we have been timely provided all of the documentation contemplated in the deposit agreement. In such case, the depositary bank will establish procedures to enable you to elect to receive either cash or additional ADSs, in each case as described in the deposit agreement.

If the election is not made available to you, you will receive either cash or additional ADSs, depending on what a shareholder in Brazil would receive upon failing to make an election, as more fully described in the deposit agreement.

*Other Distributions*

Whenever we intend to distribute property other than cash, common shares or rights to purchase additional common shares, the depositary may distribute such other property, but only if

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) we timely provide evidence satisfactory to the depositary that it may lawfully distribute such other property,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) we indicate that we wish such other property to be made available to holders of ADSs, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the depositary determines that making such other property so available is lawful and reasonably practicable.

If any of clauses (i) through (iii) of the preceding sentence are not satisfied, the depositary may sell such securities or property and distribute any net proceeds in the same way it distributes cash.

------

The distribution will be made net of fees, expenses, taxes and governmental charges payable by holders under the terms of the deposit agreement. In order to pay such taxes and governmental charges, the depositary may sell all or a portion of the property received.

o the extent the depositary determines in its discretion that any distribution is not practicable with respect to any ADS holder, the depositary may make such distribution as it deems practicable, including the distribution of foreign currency, securities or property, or it may retain such items, without paying interest on or investing them, on behalf of the ADS holder as deposited securities. Neither we nor the depositary will be liable for (i) any failure to accurately determine whether it is lawful or practicable to make the property described in this section available to holders of ADSs in general or you in particular, nor (ii) any loss incurred in connection with the sale or disposal of such property.

**Redemption**

Whenever we decide to redeem any of the securities on deposit with the custodian, we will notify the depositary bank in advance. If it is practicable and if we provide all of the documentation contemplated in the deposit agreement, the depositary bank will provide notice of the redemption to the holders.

The custodian will be instructed to surrender the shares being redeemed against payment of the applicable redemption price. The depositary bank will convert into U.S. dollars upon the terms of the deposit agreement the redemption funds received in a currency other than U.S. dollars and will establish procedures to enable holders to receive the net proceeds from the redemption upon surrender of their ADSs to the depositary bank. You may have to pay fees, expenses, taxes and other governmental charges upon the redemption of your ADSs. If less than all ADSs are being redeemed, the ADSs to be retired will be selected by lot or on a pro rata basis, as the depositary bank may determine.

**Changes Affecting Common Shares**

The common shares held on deposit for your ADSs may change from time to time. For example, there may be a change in nominal or par value, a split-up, cancellation, consolidation or reclassification of such common shares or a recapitalization, reorganization, merger, consolidation, or sale of all or substantially all of our assets.

If any such change were to occur, the depositary may, with our approval, and must, upon our request, (i) distribute additional ADSs as in the case of a stock dividend on the common shares; (ii) amend the deposit agreement and the applicable ADRs; (iii) amend the applicable registration statement in respect of the ADSs; (iv) call for the surrender of outstanding ADRs to be exchanged for new ADRs and (v) take such other actions as are appropriate to reflect such change with respect to the ADSs. If the depositary does not choose any of the foregoing, any of the cash, securities or other property it receives will constitute part of the deposited property and each ADS will then represent a proportionate interest in such property.

**Issuance of ADSs upon Deposit of Common Shares**

The depositary may create ADSs on your behalf if you or your broker deposit common shares with the custodian. The depositary will deliver these ADSs to the person you indicate only after you pay any applicable issuance fees and other charges of the depositary, any governmental charges and taxes payable for the transfer of the common shares to the custodian and any stock transfer or registration fees for the registration of transfer of the common shares on any applicable register and after you deliver any necessary instruments or confirmations of transfer. Your ability to deposit common shares and receive ADSs may be limited by U.S. and Brazilian legal considerations applicable at the time of deposit.

The issuance of ADSs may be delayed until the depositary or the custodian receives confirmation that all required approvals have been given and that the common shares have been duly transferred to the custodian. The depositary will only issue ADSs in whole numbers.

------

**Transfer, Combination and Split Up of ADRs**

As an ADR holder, you will be entitled to transfer, combine or split up your ADRs and the ADSs evidenced thereby. For transfers of ADRs, you will have to surrender the ADRs to be transferred to the depositary and also must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· ensure that the surrendered ADR is properly endorsed or otherwise in proper form for transfer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· provide such proof of identity and genuineness of signatures as the depositary deems appropriate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· provide any transfer stamps required by the State of New York or the United States; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· pay all applicable fees, charges, expenses, taxes and other government charges payable by ADR holders pursuant to the terms of the deposit agreement, upon the transfer of ADRs.

To have your ADRs either combined or split up, you must surrender the ADRs in question to the depositary with your request to have them combined or split up, and you must pay all applicable fees, charges and expenses payable by ADR holders, pursuant to the terms of the deposit agreement, upon a combination or split up of ADRs.

The Depositary may appoint one or more co-transfer agents to effect transfers, combinations and split ups of ADRs. The co-transfer agent(s) will be entitled to the same protection and indemnity as the depositary and will agree to be bound by the terms of the deposit agreement.

**Withdrawal of Common Shares Upon Cancellation of ADSs**

As a holder, you will be entitled to present your ADSs to the depositary for cancellation and then receive the corresponding number of underlying common shares at the custodian's office. Your ability to withdraw the common shares is subject to the provisions of or governing the deposited securities, and of the deposit agreement, any ADRs evidencing the ADSs, the rules of the Central Clearing System of the B3 (*Central Depositária da B3*), the Company's *estatuto* (bylaws) and applicable law. In order to withdraw the common shares represented by your ADSs, you will be required to pay to the depositary the fees for cancellation of ADSs and any charges and taxes payable upon the transfer of the common shares being withdrawn. The withdrawn common shares will be delivered at the office of the custodian. Once canceled, the ADSs will not have any rights under the deposit agreement.

If you hold ADSs registered in your name, the depositary may ask you to

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) provide proof of identity and genuineness of any signature,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) provide such other information as the depositary may deem necessary or proper including without limitation information as to citizenship, residence, exchange control approval, beneficial ownership of any securities, compliance with applicable law, regulations, provisions of or governing deposited securities and terms of the deposit agreement and the form of ADR, as the depositary may deem necessary or proper, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) comply with such regulations as the depositary may establish consistent with the deposit agreement and any regulations which the depositary is informed of in writing by us which are deemed desirable by us, the depositary or the custodian to facilitate compliance with any applicable rules or regulations of the Central Bank or the CVM.

You will have the right to withdraw the securities represented by your ADSs at any time except for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Temporary delays that may arise because (i) the transfer books for the common shares or ADSs are closed, or (ii) common shares are immobilized on account of a shareholders' meeting or a payment of dividends;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Obligations to pay fees, taxes and similar charges; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Restrictions imposed because of laws or governmental regulations applicable to ADSs or the withdrawal of securities on deposit.

------

The deposit agreement may not be modified to impair your right to withdraw the securities represented by your ADSs except to comply with mandatory provisions of law.

**Suspension of Certain Actions by Depositary**

The depositary may suspend the issuance of ADSs, the acceptance of deposits of common shares, the registration, registration of transfer, split-up or combination of ADSs or the withdrawal of deposited securities, generally or in particular instances, when the ADS register or any register for deposited securities is closed or when any such action is deemed advisable by the depositary or by us.

**Voting Rights**

As a holder, you generally have the right under the deposit agreement to instruct the depositary to exercise the voting rights, if any, for the common shares and any other securities represented by your ADSs. The voting rights of holders of common shares are described in "—Item 9.A.7. Other rights—Voting Rights of Common Shares."

As soon as practicable after receipt from us of notice of any meeting or solicitation of consents or proxies, the depositary will mail to you a notice stating (a) such information as is contained in such notice and any solicitation materials, (b) that each holder on the record date set by the depositary will be entitled to instruct the depositary as to the exercise of the voting rights, if any, pertaining to the securities represented by the holder's ADSs and (c) the manner in which such instructions may be given. Upon receipt of instructions of a holder in the manner and on or before the date established by the depositary for such purpose, the depositary will endeavor insofar as practicable and permitted under applicable law, the provisions of the deposit agreement, the bylaws, and the provisions of or governing deposited securities to vote or cause to be voted the deposited securities represented by such holder's ADSs in accordance with such instructions. If the depositary does not receive instructions of a holder before the date established by the depositary for such purpose, such holder will be deemed absent from the meeting, and no vote will be recorded in respect of such holder. The depositary will not itself exercise any voting discretion in respect of any deposited securities.

We cannot assure you that you will receive voting materials in time to enable you to return voting instructions to the depositary in a timely manner. Securities for which no voting instructions have been received will not be voted.

**Record Dates**

The Depositary may, after consultation with us, if practicable, fix a record date, which, to the extent applicable, will be as near as practicable to any corresponding record date set by us for the determination of the ADS holders who will be (i) responsible for the fee assessed by the depositary for administration of the ADS program and for any expenses provided for in the deposit agreement and (ii) entitled to receive any distribution on or in respect of deposited securities, to give instructions for the exercise of any voting rights, to receive any notice or to act in respect of other matters and only such holders will be so entitled or obligated.

**Amendments and Termination**

We may agree with the depositary to modify the deposit agreement at any time without your consent. Any amendments or supplements to the deposit agreement which impose or increase any fees or charges (other than charges in connection with foreign exchange control regulations, and taxes and other governmental charges, delivery and other such expenses), or which otherwise materially prejudices any substantial existing rights of holders of ADSs do not become effective until the expiration of 30 days after notice of such amendment or supplement has been given to holders of ADSs. If a holder of ADSs continues to hold ADSs after being so notified, such ADS holder is deemed to agree to such amendment. Any amendments or supplements will be deemed not to prejudice any substantial rights or ADS holders if they (i) are reasonably necessary for the ADSs to be registered under the Securities Act or for the ADSs or common shares to be eligible for book-entry settlement, and (ii) in each case do not impose or increase the fees and charges you are required to pay. In addition, an amendment can become effective before notice is given if this is necessary to ensure compliance with a new law, rule or regulation.

The deposit agreement cannot be amended to impair your right to withdraw the common shares represented by your ADSs (except in order to comply with mandatory provisions of applicable law).

------

The depositary may resign by delivery of written notice to us of its election to do so, and we may remove the depositary by delivery of written notice to the depositary of such removal. The depositary shall, upon our request, terminate the deposit agreement by distributing notice of such termination to holders of ADSs at least 30 days prior to the date of termination. If 90 days shall have expired after (i) the depositary shall have delivered to us a written notice of its election to resign, or (ii) we shall have delivered to the depositary a written notice of the removal of the depositary, and, in either case, a successor depositary shall not have been appointed and accepted its appointment, the depositary may terminate the deposit agreement by distributing notice of such termination to the holders of all ADSs then outstanding at least 30 days prior to the date fixed in such notice for such termination.

After termination, the depositary and its agents will perform no further acts under the deposit agreement except to receive and hold (or sell) distributions on deposited securities and deliver deposited securities being withdrawn. At any time after the date of termination, the depositary will sell the deposited securities and will thereafter (as long as it may lawfully do so) hold in a segregated account the net proceeds of such sales, together with any other cash then held by it under the deposit agreement, without liability for interest, in trust for the *pro rata* benefit of the holders of ADSs who have not yet surrendered their ADSs. After making such sale, the depositary will have no further obligations in respect of the deposit agreement, except to account for such net proceeds and other cash.

**Disclosure of Interests**

To the extent that the provisions of or governing any deposited securities may require disclosure of or impose limits on beneficial or other ownership of deposited securities and other securities, and may provide for blocking transfer, voting or other rights to enforce such disclosure or limits, all persons holding ADSs agree to comply with all such disclosure requirements and ownership limitations and to cooperate with the depositary in its compliance with any instructions from us in respect thereof.

**Books of Depositary**

The depositary or its agent will maintain at a designated transfer office a register for the registration, registration of transfer, combination and split-up of ADSs. You may inspect such records at such office at all reasonable times but solely for the purpose of communicating with other holders in the interest of the business of our company or matters relating to the deposit agreement.

The depositary will maintain in New York facilities for the delivery and receipt of ADSs. The ADS register may be closed from time to time when deemed expedient by the depositary or requested by us.

**Limitations on Obligations and Liabilities**

The deposit agreement limits our obligations and the depositary's obligations to you. Neither we nor the depositary nor our agents will be liable:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· if any present or future law, rule, regulation, fiat, order or decree of the United States, the Federative Republic of Brazil or any other country, or of any governmental or regulatory authority or any securities exchange or market or automated quotation system, the provisions of or governing any deposited securities, any present or future provision of our charter, any act of God, war, terrorism, pandemic or other circumstance beyond its control shall prevent or delay or cause any of us, the depositary or our agents to be subject to any civil or criminal penalty in connection with, any act which the deposit agreement or the ADRs provides shall be done or performed by it (including, without limitation, voting);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· if it exercises or fails to exercise discretion under the deposit agreement, the ADRs or the provisions of or governing the common shares, including any failure to determine that any distribution or action may be lawful or reasonably practicable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· if it performs its obligations without negligence or bad faith;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· if it takes any action or inaction in reliance upon the advice of or information from legal counsel, accountants, any person presenting shares for deposit, any holder of ADSs, or any other person believed by it in good faith to be competent to give such advice or information;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· if it fails to determine that it may be lawful or feasible to make rights available to holders in general or to any holder in particular;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· if it relies upon any written notice, request, direction or other document believed by it to be genuine and to have been signed or presented by the proper party or parties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· for the inability by a holder of ADSs to benefit from any distribution or other benefit made available to holders of common shares but not, under the terms of the deposit agreement, made available to holders or any particular holder of ADSs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· for any action or inaction of any clearing or settlement system (and any participant thereof) for the deposited property or the ADSs; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· for any consequential or punitive damages (including lost profits) for any breach of the deposit agreement.

Neither the depositary nor its agents have any obligation to appear in, prosecute or defend any action, suit or other proceeding in respect of any deposited securities or the ADSs, which in its opinion may involve it in expense or liability, unless indemnity satisfactory to it against all expense (including fees and disbursements of counsel) and liability be furnished as often as may be required (and no Custodian shall be under any obligation whatsoever with respect to such proceedings, the responsibility of the Custodian being solely to the Depositary). We and our agents shall only be obligated to appear in, prosecute or defend any action, suit or other proceeding in respect of any deposited securities or the ADSs, which in our opinion may involve us in expense or liability, if indemnity satisfactory to us against all expense (including fees and disbursements of counsel) and liability is furnished as often as may be required. The depositary shall not be liable for the acts or omissions made by any securities depository, clearing agency or settlement system in connection with or arising out of book-entry settlement of deposited securities or otherwise. Furthermore, the depositary shall not be responsible for, and shall incur no liability in connection with or arising from, the insolvency of any custodian that is not a branch or affiliate of Citibank, N.A.

The depositary has no obligation to inform ADS holders or any other holders of an interest in an ADS about the requirements of Brazilian law, rules or regulations or any changes therein or thereto.

Neither the depositary nor any of its agents shall be liable to holders of ADSs or beneficial owners of interests in ADSs for any indirect, special, punitive or consequential damages (including, without limitation, lost profits) of any form incurred by any person or entity, whether or not foreseeable and regardless of the type of action in which such a claim may be brought.

Additionally, none of us, the depositary or the custodian shall be liable for the failure by any holder of ADSs or beneficial owner therein to obtain the benefits of credits on the basis of non-U.S. tax paid against such holder's or beneficial owner's income tax liability. Neither we nor the depositary shall incur any liability for any tax consequences that may be incurred by holders or beneficial owners of ADSs on account of their ownership of ADSs or ADSs.

The depositary and its agents may fully respond to any and all demands or requests for information maintained by or on its behalf in connection with the deposit agreement, any holder or holders of ADRs, any ADS or ADSs or otherwise related to the deposit agreement to the extent such information is requested or required by or pursuant to any lawful authority, including without limitation laws, rules, regulations, administrative or judicial process, banking, securities or other regulators.

The depositary shall not incur liability for the content of any information submitted to it by us or on our behalf for distribution to the holders of ADSs or for any inaccuracy of any translation thereof, for any investment risk associated with acquiring an interest in the deposited securities, for the validity or worth of the deposited securities, for the credit-worthiness of any third party, for allowing any rights to lapse upon the terms of the deposit agreement or for the failure or timeliness of any notice from us.

So long as it acted without bad faith or negligence, the depositary shall not be liable for any acts or omissions made by a successor or predecessor depositary.

The depositary and its agents will not be responsible for any failure to carry out any instructions to vote any of the deposited securities, for the manner in which any such vote is cast or for the effect of any such vote.

------

The depositary and its agents may own and deal in any class of securities or our company or our affiliates and in ADSs.

**Taxes**

You will be responsible for the taxes and other governmental charges payable by the custodian or the depositary with respect to the ADSs, ADRs, any deposited securities or other property represented by the ADSs or any distributions thereon. We, the depositary or the custodian may deduct from any distribution the taxes and governmental charges payable by holders and may sell any and all property on deposit to pay the taxes and governmental charges payable by holders. If any tax or governmental charge is required to be withheld on any non-cash distribution, the depositary may sell the distributed property or securities in such amounts and in such manner as the depositary deems necessary and practicable to pay such taxes and shall distribute any remaining net proceeds or the balance of such property or securities to the holders entitled thereto. You will be liable for any deficiency if the sale proceeds do not cover the taxes that are due.

The depositary may refuse to effect any registration, registration of transfer, split-up or combination of ADRs or any withdrawal of deposited securities until all taxes and charges are paid by the applicable holder. The depositary and the custodian may take reasonable administrative actions to obtain tax refunds and reduced tax withholding for any distributions on your behalf. However, you may be required to provide to the depositary and to the custodian proof of taxpayer status and residence and such other information as the depositary and the custodian may require to fulfill legal obligations. You are required to indemnify us, the depositary and the custodian and our respective directors, employees, agents and affiliates for any claims with respect to taxes, additions to tax, penalties or interest arising out of any refund of taxes, reduced rate of withholding at source or other tax benefit obtained for you, as well as any claims with respect to taxes (including applicable interest and penalties thereon) arising from any ADSs held by you, the deposited property represented by the ADSs and any transaction entered into by you in respect of the ADSs and/or the deposited property represented thereby.

**Foreign Currency Conversion**

The depositary bank will arrange for the conversion of all foreign currency received into U.S. dollars if such conversion is practical, and it will distribute the U.S. dollars in accordance with the terms of the deposit agreement. You may have to pay fees and expenses incurred in converting foreign currency, such as fees and expenses incurred in complying with currency exchange controls and other governmental requirements.

If the conversion of foreign currency is not practical or lawful, or if any required approvals are denied or not obtainable at a reasonable cost or within a reasonable period, the depositary bank may take the following actions in its discretion:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Convert the foreign currency to the extent practical and lawful and distribute the U.S. dollars to the holders for whom the conversion and distribution is lawful and practical.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Distribute the foreign currency to holders for whom the distribution is lawful and practical.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Hold the foreign currency (without liability for interest) for the applicable holders.

**Available Information**

The deposit agreement, the provisions of or governing deposited securities and any written communications from us, which are both received by the custodian or its nominee as a holder of deposited securities and made generally available to the holders of deposited securities, are available for inspection by ADS holders at the offices of the depositary.

**Governing Law**

The deposit agreement is governed by and shall be construed in accordance with the laws of the State of New York. In the deposit agreement, we have submitted to the jurisdiction of the federal and states courts in the City of New York and appointed an agent for service of process on our behalf.

------

**Registered Capital**

An electronic registration has been issued in the name of the depositary with respect to the ADSs and is maintained by the custodian on behalf of the depositary. Pursuant to the registration, the custodian and the depositary are able to convert dividends and other distributions with respect to the common shares represented by ADSs into foreign currency and remit the proceeds outside Brazil. If a holder of ADSs exchanges such ADSs for common shares, such holder will be entitled to continue to rely on the depositary's registration for five business days after such exchange, following which such holder must seek to obtain its own electronic registration with the Central Bank, constituting a Brazilian financial institution as their representative for such purposes. Thereafter, any holder of common shares may not be able to convert into foreign currency and remit outside Brazil the proceeds from the disposition of, or distributions with respect to, such common shares, unless such holder is a duly qualified investor under Resolution No. 4,373 and obtains its own electronic registration.

## Exhibit 12.1

**Exhibit 12.1**

**CERTIFICATION**

I, Christian Mauad Gebara, certify that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.&nbsp;&nbsp;&nbsp;&nbsp; I have reviewed this annual report on Form 20-F of Telefônica Brasil S.A.;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.&nbsp;&nbsp;&nbsp;&nbsp; Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.&nbsp;&nbsp;&nbsp;&nbsp; Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the financial condition, results of operations and cash flows of the company as of, and for, the periods presented in this report;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.&nbsp;&nbsp;&nbsp;&nbsp; The Company's other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the company and have:
