A.       History and Development of the Company

Basic Information

TIM S.A., formerly known as Intelig Telecomunicações Ltda., a publicly held company (sociedade anônima) organized under the laws of the Federative Republic of Brazil, incorporated in the Federative Republic of Brazil for an indefinite period on March 9, 1998.

Our headquarters are located at João Cabral de Melo Neto Avenue, 850 – South Tower – 12^th floor, 22775-055 Rio de Janeiro, Brazil and our telephone number is +55 (21) 4109-4167.

Our agent for service of process in the United States is Puglisi & Associates located at 850 Library Avenue, Suite 204, Newark, Delaware 19711.

The SEC maintains an Internet site that contains reports, proxy and information statements and other information regarding issuers that file electronically with the SEC at http://sec.gov. Our web site address is http://www.tim.com.br. Information contained on, or that can be accessed through, our website does not constitute a part of this Annual Report.

Historical Background

In July 1998, as part of the privatization of Telebrás, the Brazilian state-owned telecommunications monopoly, the Federal Government sold substantially all its shares of the 12 holding companies into which Telebrás had initially been broken up, including its shares of Tele Sudeste Celular Participações S.A. (“TSU”), and Tele Nordeste Celular Participações S.A. (“TND”). Following a series of acquisitions, corporate reorganizations and corporate name changes, TSU and TND merged to form TIM Participações in 2004.

We continued to expand and restructure our operations through a series of corporate reorganizations, mergers, acquisitions and name changes, and we are currently held, directly and indirectly, by Telecom Italia (which began operating in Brazil in 1998 as Telecom Italia Mobile) through its wholly owned subsidiary, TIM Brasil, formed in 2002 as the holding company of Telecom Italia’s operating companies in Brazil. In turn, the single largest shareholder of Telecom Italia is Vivendi, which is able to exercise significant influence over Telecom Italia. In 2019, Telecom Italia delisted all of its U.S. listed securities and deregistered from the SEC, having filed Form 15F on July 9, 2019. See “—C. Organizational Structure” for a description of our current corporate structure and Exhibit 8.1 attached hereto for a list of our significant subsidiaries as of the date of this annual report.

In 2009, the acquisition of Holdco Participações Ltda. (“Holdco”), holder at the time of 100% of Intelig’s capital, was approved and Intelig became a wholly owned subsidiary of TIM after this transaction. The acquisition of Intelig (known since September 2017 as TIM S.A.) brought material advantages through significant synergies with its network, such as its metropolitan optimal fiber network and its large backbone that allowed us to accelerate the development of our 3G network and generate significant operational cost savings.

In 2011, TIM Celular, which merged into the Company as a result of the Reorganization, entered into an agreement with Companhia Brasiliana de Energia and AES Elpa (the AES Group in Brazil) for the purchase of all of AES Elpa’s equity interests in Eletropaulo Telecomunicações and 98.3% of the interest of AES RJ, (“AES Atimus Acquisition”). In connection with the acquisition, Eletropaulo Telecomunicações changed its corporate name to TIM Fiber SP Ltda. (“TIM Fiber SP”), and AES RJ changed its corporate name to TIM Fiber RJ S.A. (“TIM Fiber RJ”). Both entities were collectively referred to as TIM Fiber. In accordance with the corporate reorganization of TIM Fiber, TIM Fiber RJ and TIM Fiber SP were merged into TIM Celular in 2012, which was the former entity that used to own and operate the fiber optic network in metropolitan São Paulo and Rio de Janeiro (and which, as

discussed below, itself was merged into the Company in October 2018 as a result of the Reorganization). The purpose of this reorganization was to simplify our organizational structure and improve the administrative, operational and financial efficiency of the companies controlled by us.

In 2013, Instituto TIM was founded with the mission to create and strengthen resources and strategies for the democratization of science, technology and innovation that promote human development in Brazil. In order to accomplish this mission, the Institute works around four pillars: Education, Inclusion, Technological Applications and Work, encouraging the democratization of free technological solutions and the creation of innovative approaches to the teaching of science and mathematics in Brazil.

On July 25, 2017, TIM’s Board of Directors approved the corporate reorganization (the “Reorganization”), of its subsidiaries TIM Celular and Intelig. On September 6, 2017, as the first phase of the Reorganization, Intelig altered its articles of association to change the company from a limited liability company to an unlisted limited liability corporation, and to change its corporate name to TIM S.A.

As will be discussed in more detail below (see “—C. Organizational Structure”), in October 2018, the reorganization resulted in the merger of TIM Celular into the Company. This merger achieved its objective of capturing operating and financial synergies, through the implementation of a more efficient operating structure, as well as accounting and internal control systems.

In 2018, Instituto TIM was acknowledged by the Ministry of Justice in Brazil as a qualified Civil Society Organization of Public Interest (“OSCIP”), which reinforced the commitment to transparency in the activities of the Institute. This achievement also brings more credibility and confidence to expand the network of partners and institutions that wish to take part in the projects supported by the TIM Institute.

On July 29, 2020, the shareholders of TIM Participações (our former parent holding company) and the shareholders of the Company approved, by majority of votes, the merger of the first into the latter, pursuant to the terms of the Protocolo e Justificação de Incorporação. On July 29, 2020, the boards of directors of each of TIM Participações and the Company approved the execution of a Merger Agreement (protocolo de incorporação) with the Company. TIM Participações merged with and into the Company, previously a wholly owned subsidiary of our former parent holding company TIM Participações (the “Merger”), which became effective on September 28, 2020. Consequently, TIM Participações, our former parent holding company, was merged into the Company as a result of the Merger. The common shares of TIM Participações had been listed on the Novo Mercado segment of the B3 S.A. – Brasil, Bolsa, Balcão (the “B3”), since 2011. In order to be listed on the Novo Mercado, we are required to comply with heightened requirements relating to corporate governance and the disclosure of information to the market and we are not permitted to issue preferred shares, participation bonuses or any kind of shares with restricted voting rights. On September 28, 2020, as a result of the Merger, TIM Participações ceased to exist, and TIM continued as the surviving corporation in the Merger, with TIM succeeding to all rights and obligations of TIM Participações pursuant to Brazilian corporate law and TIM became the successor registrant under Rule 12g-3(a) under the Exchange Act. On September 28, 2020, the B3 approved the listing of the Company and the admission to trading of its shares on the Novo Mercado. On September 28, 2020, TIM filed a form 6-K pursuant to Rule 12g-3(a) promulgated under the Exchange Act to report this succession in accordance with Rule 12g-3(f) promulgated under the Exchange Act. Pursuant to Rule 12g-3(a) under the Exchange Act, TIM common shares and TIM ADSs, as common shares and ADSs of the successor issuer, were deemed registered under Section 12(b) of the Exchange Act. TIM Participações S.A.’s common shares and ADSs continued to be traded until October 13, when Company’s common shares and ADSs started to trade on the B3 and the NYSE, respectively. See “Item 9. The Offer and Listing—A. Offer and Listing Details.”

On March 10, 2020, we disclosed to the market that we, jointly with Telefônica Brasil S.A. (“VIVO”), expressed to Bank of America Merrill Lynch (“BofA”), Oi Group’s financial advisor, our interest in a potential joint acquisition of Oi Group’s UPI mobile business, in whole or in part, so that, in the event of the completion of the operation, each of the interested parties would receive a portion of that business.

 We believe that the transaction would have the potential to add +14.5 million clients, +7.2 thousand sites and towers, +49 MHz of spectrum to our operations, enabling us to close historical operational and structural gaps,

generating benefits for our customers and shareholders, by accelerating our growth, increasing operational efficiency and quality of service.

On July 18, 2020, we submitted, together with VIVO and Claro S.A. (“CLARO”) a binding offer to Oi Group for the acquisition of the totality of the mobile assets operation of the Oi Group, or the UPI Mobile Business, as revised on July 27, 2020 and September 7, 2020. The latter was accepted by Oi Group on December 14, 2020.

On December 14, 2020, TIM along with CLARO and VIVO, was declared the winner of the competitive process of the sale of assets of the mobile telephony operation (Personal Mobile Service) of the Oi Group. In February 2022, the transaction received regulatory approval from CADE and Anatel. Closing of the transaction is expected to occur on April 20, 2022.

Pursuant to our offer, the total amount of the transaction is R$16.5 billion plus the value of the compensation offered to the Oi Group for certain take-or-pay data transmission capacity agreements, to be executed at the time of the closing of the transaction. Such agreements have a net present value corresponding to approximately R$819 million as of December 31, 2020. The R$16.5 billion amount includes R$15.7 billion related to the base price of the offer and R$756 million corresponds to transition services to be rendered for up to twelve months by Oi Group, of which TIM will be responsible for R$318 million. We expect to disburse R$7.3 billion, or 44% of the total base price and transition services. Concerning the capacity agreements, we expect to be responsible for payments of approximately R$476 million, or 58% of the net present value of the agreements.

Partnership with C6 Bank

On March 26, 2020 we entered into a commercial agreement with Banco C6 S.A. (“C6 Bank”), pursuant to which we have been granted, on February 1, 2021, the right to subscribe an indirect equity interest of approximately 1.4% in C6 Bank through the exercise of subscription bonuses, subject to certain agreed upon thresholds. By the end of 2021, we had been granted the right to subscribe for an indirect equity interest of approximately 4.08%.

However, certain elements of this partnership are currently being disputed and so we may not obtain all of the expected benefits of the partnership. We commenced an arbitration procedure No. 28/2021/SEC8 before the Arbitration and Mediation Center of the Brazil-Canada Chamber of Commerce by TIM against Banco C6 S.A., Carbon Holding Financeira S.A. and Carbon Holding S.A., pertaining to the interpretation of certain contractual clauses of the contracts governing the partnership between the parties. As a potential result of this arbitration, the strategic partnership may be terminated.

TIM and Vivo new sharing agreement

In September 2020, the competent authorities (CADE and Anatel) approved the new sharing agreement established between TIM and VIVO, for: (i) sharing of the 2G network, allowing one operator to switch-off its 2G network, where both parts are currently present, and the remaining operator will provide “roaming like” services for the customers of both operators and (ii) establish new infrastructure sharing agreements for the 3G and 4G network (Single-Grid), directed to cities with fewer than 30,000 inhabitants, which in the future may be expanded to larger cities. We believe that carrying out this agreement will result in synergies and efficiencies that could help support us in continuing to provide innovative and standard-setting offerings and services, as well as synergies and efficiencies in the allocation of investments and operating costs.

In relation to our sharing of the 2G network, the renowned GWCN (Gateway Core Network) technical solution was approved and carried out during 2021, while quality KPIs were monitored. As a result of the sharing agreement, TIM switched-off its 2G network in five cities in the state of Espírito Santo and seven cities in the state of São Paulo; Vivo switched-off four cities in the state of Rio de Janeiro and eight cities in the state of São Paulo. All the switched-off cities had less than 30,000 inhabitants and were each already covered by access to 3G or 4G .

With respect to the single grid agreement, each party was able to increase its 3G and 4G coverage in more than 300 cities with a total of 422 shared sites, as at May 2021. The agreement remains in force and includes a detailed rollout that is expected to be concluded by 2023.

TIM and Stellantis connected cars partnership

In October 2020, TIM and Fiat Chrysler Automóveis (FCA), now known as Stellantis, established a partnership to offer connectivity solutions embedded in vehicles of the Fiat, Jeep and RAM brands in Brazil from the first half of 2021. As part of the global strategy of developing ecosystems for connected services and to enhance the digital experience of customers, future Stellantis launches in the country will rely on eSIM, with the LTE coverage quality and TIM's IoT network. As a result, future Stellantis vehicle launches in Brazil will have access to native Wi-Fi onboard eSIM and the cars’ active and real-time communication with the user, the Stellantis and the dealer network. In addition to such features, this technology will focus on safety, allowing remote identification of possible vehicle failures with the possibility of more agile and accurate diagnoses.

During 2021, a Proof of Concept (“PoC”) was launched in the Stellantis factory in Goiana/PE using 5G connectivity to investigate the benefits of this technology, and enabling the use of new applications on a large scale, from the use case of artificial intelligence for the automated processing of images. The PoC is ongoing and will enter a new phase which will enable an Edge Cloud environment, achieving greater computing capacity, greater scalability, and allowing the application to have high capacity and greater sensitivity to latency.

Partnership with TIP and INATEL

Also in October 2020, TIM announced a partnership with TIP (Telecom Infra Project), for developing OpenRAN (Open Radio Access Network) technology by means of the Open Field Program. The initiative will be hosted by INATEL (Instituto Nacional de Telecomunicações) in the city of Santa Rita do Sapucaí, in the state of Minas Gerais, Brazil. The goal is to create an adequate environment (living lab) to test, validate and accelerate products and new functionalities of open and disaggregated technologies solutions for Radio Access Network, by performing network testing, product validation, feature analysis and recommendation based on friendly users’ usage and feedback. The program will last until 2022.

FiberCo Formation and Sale of Equity Interest

On December 10, 2020, our Board of Directors approved the formation of FiberCo Soluções de Infraestrutura Ltda. (“FiberCo”), in preparation for a possible future segregation of assets and provision of fiber infrastructure services. This process is one of the intermediate steps in the transformation of our broadband services, and it aims to create an open fiber infrastructure vehicle to allows us to attract a strategic partner as a shareholder of FiberCo. We expect FiberCo to operate in the wholesale market and to provide fiber connectivity services for last-mile and transport network, for all market operators, with the Company as an anchor customer. We expect FiberCo to allow us to achieve the expected growth in the Brazilian fiber market in the coming years, taking advantage of the open network approach and a focused operating model. This transaction aims to accelerate the growth of the residential broadband business and unlock additional value from our existing infrastructure. Accordingly, on March 3, 2021, we entered into an exclusivity agreement with IHS Brasil Participações Ltda. (“HIS”), a large and diversified provider of telecommunications infrastructure, to negotiate the terms and conditions for the acquisition of equity interest, by IHS, in FiberCo. The operation was approved by CADE in June 16, 2021 and by Anatel in November 11, 2021.

2021 Important Events

5G Auction

The 5G auction was held in November 2021. In the auction, we acquired 11 lots, with a total value offered of R$1.05 billion, in three frequency bands: 3.5 GHz, 2.3 GHz and 26 GHz. The acquired bands have a set of obligations that must be met with financial contributions or the construction of mobile and fixed network infrastructure. As a result, TIM guarantees the necessary spectrum capacity to follow its growth journey in the mobile telephony market nationwide, being prepared for its customers’ demands and to explore new applications and develop innovative solutions that demand high-speed connectivity and capacity.

The main commitments associated with each band are as follows:

Partnership between TIM and Cogna

On July 7, 2021, we informed our shareholders, the market in general and other stakeholders that, together with Anhanguera Educacional Participações S.A. (“AESAPAR”), a subsidiary of Cogna Educação S.A. (“Cogna”), jointly referred to as “Partners”, it completed the negotiations regarding a strategic partnership (“Partnership”) with the objective of developing offers combined with special benefits aimed at providing distance education through the Ampli platform.

The Partners highlighted the innovative nature of the Partnership, by joining a digital teaching platform developed in a mobile-first concept, with the largest 4G infrastructure in Brazil. This is a powerful combination that will expand and encourage access to university and free courses for all TIM customers. This approach provides great potential to generate value for both companies through customer base growth and revenue growth.

The Partnership fits into our customer platform strategy that we have been working on since 2020. This strategy seeks to monetize the assets that TIM holds as a mobile operator through strategic partnerships that generate value for our customers and for the company.

This decision does not create a joint venture and, therefore, TIM maintains the independence of its operations. Through a compensation mechanism based on objectives and depending on the results of the partnership, TIM will become a minority partner of AESAPAR in a new company to be established as a result of the separation of assets from the Ampli platform (“Ampli Co”). The establishment and operation of Ampli Co will be submitted by AESAPAR to the competent authorities, in particular to the Ministry of Education.

TIM's interest in Ampli Co may reach up to 30% of its capital and the subscription of shares must be approved in advance by the Brazilian Antitrust Enforcement Agency (CADE). In the defined plan, Ampli Co is expected to undertake an IPO.

Completion of the transaction between IHS and I-Systems

On November 16, 2021, after regulatory authorizations from Anatel and CADE IHS Fiber Brasil (“IHS"), acquired from us an equity interest in FiberCo Soluções de Infraestrutura S.A. (“FiberCo”), a company that was incorporated by TIM to segregate network assets and provide infrastructure services.

As a result of the transaction, IHS currently holds 51% of FiberCo’s share capital, with the remaining 49% remaining under the control of TIM.

FiberCo’s operations include approximately 15,000 km of fiber in a secondary network, covering approximately 6.4 million homes (homes passed), 3.5 million of which in FTTH (fiber to the home) and 3.4 million in FTTC (fiber to the curb), which constitute the initial base of assets transferred by TIM. The homes connected account for approximately 700,000 over which FiberCo will provide operation and maintenance services to TIM. Moreover, approximately 140 employees were transferred to FiberCo, as well as other assets and contracts, all exclusively related to the scope of its activities.

With the completion of the acquisition, FiberCo changed its corporate name to I-Systems, and began its journey as an infrastructure vehicle with the mission of deploying, operating and maintaining last-mile infrastructure for broadband access to be offered in the wholesale market, having TIM as an anchor customer.

Capital Expenditures

Capital expenditures totaled R$4,382 million in 2021, up 12.6% as compared to 2020. This increase can mainly be explained by the projects undertaken in preparation of the integration of our infrastructure with Oi’s mobile assets. In 2021, our total capex, including participation in the 5G auction, was R$7,966 million. The actual amount and timing of our future capital expenditures may be affected by foreign exchange oscillations and other impacts from financial or economic crises. For a detailed breakdown of our capital expenditures in 2021, 2020 and 2019 and those currently in progress, as well as the total amount each year and method of financing, see “Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Uses of Funds—Material Capital Expenditures” and “—Sources of Funds.”

On March 16, 2020, we released our Industrial Plan for 2020-2022, which demonstrates our transformation as a result of the execution of our previous Industrial Plans. These changes include, notably, network improvements and an improved customer experience, as recognized by independent third parties, and ongoing innovations in network evolution, including 5G trials, multiple-input multiple-output technology, or Massive-MIMO, repurposing frequency bands that have historically been allocated for 2G mobile services and that are being migrated to other frequencies (known as refarming), and the Vivo MoU (see Item 4. Information on the Company—B. Business Overview—Our Business). Through specific and disciplined investments in new technologies and processes, we seek to reach a position that allows us to act on new opportunities to sustain revenue growth, increase profitability, develop our infrastructure and expand cash flow generation. We focus on improvement of returns on investment as well as customer experience maximization, but we are also committed to our role in society by promoting environmental, social and governance initiatives that will result in a positive transformation for all stakeholders.

We expect that IT initiatives such as big data evolution, the rollout of “next best action,” or NBA, cognitive systems, and application and architecture review in a two-year time frame will advance our IT in a manner that will provide us with an enhanced view of our customers’ lifecycle and consumption patterns, as well as allowing for faster time-to-market, development of new capabilities, process automation, and increased efficiency. Our approach to investment in our network has a five-part focus, as follows: data growth, 5G ready, IoT, fixed broadband, and new initiatives. The benefits expected are network decommissioning savings, a convergent architecture, fixed wireless access improvement, network densification, innovative solutions and new IoT business opportunities.

The capital expenditure expected to support the Industrial Plan for 2021-2023 was approximately R$13.0 billion, considering TIM S.A. operation on a standalone approach, and R$13.5 billion considering the combination with the UPI Oi Mobile Assets for that three-year period. Some smart capital expenditure initiatives in development our infrastructure are disruptive business models for our infrastructure. With the use of new technologies, such as Massive-MIMO technology, and with network sharing agreements, it will be possible for us to reach locations that were not previously financially viable.

On February 23, 2022, we updated our strategic plan after a year of consistent improvements, which included the successful achievement of our short-term objectives outlined in our previous strategic plan for 2021-2023. We managed to implement our strategy to achieve these objectives despite a more pressured and unstable macroeconomic environment that frustrated projections made by the market in general. In this context, our focus on execution, with flexible decision making and appropriate prioritization, were crucial.

For the next three year period, our plan takes into account (i) the estimated effects of the acquisition of the assets of Oi Móvel SA, since the transaction received regulatory approval from the sector regulator (Anatel) and the competition regulator (CADE) (see material facts of January 31 and February 9, 2022); (ii) the effects of the beginning of the adoption of 5G technology and the obligations and commitments that we agreed to as part of our competitive bids in the 5G frequency auctions, (see material fact disclosed on November 5, 2021) in Brazil; and (iii) the change to a new coverage growth model for our residential broadband service after the segregation of our network assets and incorporation of I-Systems, (see material fact disclosed on November 16, 2021). Under this new set of assumptions, we also reaffirm our commitment to (i) the sustainable evolution of service revenue; (ii) the improvement of our operating cash generation, through strong EBITDA (iii) maintain an adequate capital allocation, characterized by the CAPEX allocated to network and IT infrastructure that improve our operational efficiency and customer experience; and (iv) the continuous expansion of cash flow as a combination of all of the above factors.

Recent Developments

TIM elects new Chief Executive Officer (CEO)

On January 31, 2022, the Company’s Board of Directors announced Mr. Alberto Mario Griselli to replace Mr. Pietro Labriola in the positions of Chief Executive Officer (CEO) and Board member. Mr. Griselli, who held the position of Company’s Chief Revenue Officer (CRO) since July 2019, holds a degree in Electronic Engineering from La Sapienza University in Rome and an MBA in finance from Columbia University. With over 20 years of experience in the telecommunications industry, he has held relevant positions such as Vice-President for Latin America at TIM, a global provider of mobile engagement solutions for telecom operators, and Managing Director for Latin America at Value Partners, a management consulting firm.

Anatel grants prior consent to transfer control of Oi’s mobile telephony activities

On January 31, 2022, Anatel, unanimously granted its consent to the implementation of the corporate transaction referring to the full transfer of control of the three specific purpose entities (“Mobile Assets SPE” or “SPE”) , which correspond to the mobile telephony activities of Oi Móvel S.A. – Under Judicial Reorganization (“Oi Móvel”), for the companies TIM, Telefônica Brasil S.A. and Claro S.A. (“Transaction”).

The consent provides for certain conditions, in line with a transaction of this nature, which mainly aim to guarantee access by small providers to nationwide networks, maintain commitments linked to the transferred radio frequencies, establish the minimum parameters of the communication plan linked to the transaction and grant users certain rights in the migration phases.

CADE approves the acquisition of most of the Oi mobile assets by TIM

On February 9, 2022, CADE under the of Concentration Act 08700.000726/2021-08, approved the implementation of the full transfer of control of the three special purpose entities which correspond to the mobile telephony activities of Oi Móvel S.A. – Under Judicial Recovery, for the companies TIM, Telefônica Brasil S.A. and Claro S.A. (the “Buyers”).

The approval provides for a set of conditions, mostly behavioral, and which were recorded in a Concentration Control Agreement (the “CC Agreement”) between the Buyers and CADE. These conditions have a modular character and can be used by new entrants and smaller operators to reduce entry barriers and leverage the exploration of different business models, without affecting TIM’s main objective of strengthening its infrastructure and closing the capacity gap spectrum compared to its main competitors that the CC Agreement was designed to strike a balance between creating value and mitigating competition concerns for the industry.

B.       Business Overview

Market Characteristics

The telecommunications sector in Brazil is marked by strong competition and by the effective regulation of Anatel, whose mission is “to promote the development of the country’s telecommunications, in order to provide it with a modern and efficient telecommunications infrastructure, capable of providing the society with adequate, diversified and fair prices throughout the entire national territory.”

Throughout 2021, the telecommunications sector continued to suffer the impacts brought on by the global COVID-19 pandemic, as well as restrictions aimed at curbing the spread of the virus. However, despite these challenges, the sector maintained a trajectory of growth in terms of data consumption, and thus operators were required to adapt their networks and face the challenge of delivering an increasingly robust infrastructure in an environment which requires greater rationality in investments, including on projects such as the densification of sites, frequency refarming, and the aggregation of carriers on two or three frequencies. Furthermore, we continue to advance in sharing initiatives focused on 4G and network transport. This evolution of our network has allowed for a significant expansion of traffic on the 4G network, which provides our customers with a better usage experience, both in terms of performance – with higher download and upload speeds and lower latency – as well as in indoor coverage and greater penetration.

Demand for the evolution of technology and investments in the sector has also continued. In particular, this can be seen in relation to the 5G auction, which was held in the last quarter of 2021 and in additional to a financial component established a series of special commitments undertaken by successful bidders related to the right-of-use of frequencies, which will likely force the sector to experience a new cycle of investments. The deployment of this new technology is expected to bring about significant technological advances, enabling the generation of new business models, encouraging an increasingly connected society, and paving the way for advances in research and development.

Lastly, 2021 proved to be a year in which the demand for fixed broadband consolidated. During the year, several smaller internet service providers launched their initial public offerings (IPOs) and strengthened their financial positions to continue growing. Fixed broadband remains a significant business opportunity in Brazil, as it still has low penetration outside major urban centers. The broadband market is also being influenced by the trend towards the separation of service providers and infrastructure providers. Instead of all service providers needing up front capital to invest in infrastructure, service providers are able to lease infrastructure from specialized infrastructure companies and thereby seek to accelerate their growth more easily without being limited by the need to build their own network infrastructure.

The Brazilian mobile market reported growth of 1.2% year-on-year (“YoY”), reinforcing its continued positive evolution. During 2021, postpaid net additions reached 16.7 million users and surpassed a 4.1 million net addition in prepaid users. Since the end of 2020, the prepaid customer base is no longer the market’s largest component, shrinking even further relative to postpaid customers in the year ended 2021. It now constitutes only 47% of total subscriber base as of December 31, 2021, as compared to 49% as of December 31, 2020. The significant reduction in the overall number of prepaid users is mainly due to the acceleration in users consolidating multiple SIM cards to a single card, high penetration of mobile service and the rapid substitution of voice with data usage, resulting in a decrease in the so-called “community effect,” where consumers value a telecommunications system more as more users adopt it. The postpaid segment, however, experienced an increase of 14% during 2021, reaching 53% of total subscriber base as of December 31, 2021, as compared to 51% as of December 31, 2021, driven by operators’ efforts to monetize their customer base, offering more data, content and digital services, and the migration of customers from prepaid to control plans, and from entrance plans to postpaid plans.

Mobile Competitors

TIM is the brand name under which we market our mobile telecommunications services, offering 5G DSS, 4G, 3G and GSM technologies. Currently, our subsidiaries hold mobile licenses for each of the ten wireless areas of Brazil recognized by Anatel, making us a mobile operator in Brazil offering complete nationwide coverage. In two of our ten areas we are the Telebrás legacy provider. See “—A. History and Development of the Company—Historical Background.” Our network covers approximately 98 % of Brazil’s population based on Anatel’s coverage criteria.

In addition to TIM, as at the end of 2021 there were three other major participants in the Brazilian mobile market that offer nationwide coverage in all Anatel wireless areas: Vivo, Claro and Oi.

With the closing of the transaction for the acquisition of Oi’s mobile assets by TIM, Vivo and Claro, the remaining major participants in the Brazilian mobile market that offer nationwide coverage in all Anatel wireless areas besides TIM will be Vivo, Claro.

The Brazilian mobile telecommunications industry is highly competitive. Any adverse effects on our results and market share from competitive pressures will depend on a variety of factors that cannot be precisely assessed and are beyond our control. Among such factors are our competitors’ size, experience, business strategies and capabilities, the prevailing market conditions and the applicable regulations.

Other Competition

We also compete with landline telephone service providers, of which the incumbent providers in Brazil (Oi, Vivo and Embratel Participações S.A. (owned by America Movil), as well as Algar Telecom, a regional incumbent), and some other relevant players (GVT, acquired by Vivo, and Net Serviços de Comunicação S.A., owned by America Movil), offer packages including voice (both fixed line and mobile), broadband and pay-TV services in bundled offers. Landline providers are, however, required to offer their services to unaffiliated mobile providers on the same basis they are offered to affiliated mobile providers. Our acquisition of Intelig (now known as TIM S.A.) and AES Atimus (later TIM Fiber, which was merged into TIM Celular in 2012, and TIM Celular was merged into the Company in 2018) broadened our participation in the fixed telecommunication sector.

In November, 2018, Anatel issued Resolution No. 703/2018, which established new maximum limits for the amount of spectrum bandwidth that a single telecommunications service provider of collective interest, as well as its affiliates, subsidiaries or controller company, when operating in the same municipality, may hold on a primary basis. This regulatory change increases the competitive environment of the sector and facilitates consolidation of operations among the main players in the market.

In recent years, in preparation of certain anticipated market events, the Brazilian telecom sector has experienced a series of broadband-centric capital markets and M&A activity, resulting in a mixture of organic growth and strategic acquisitions. The 3.5GHz rights that were acquired at auction by regional providers will open an opportunity for them to become mobile network operators. Additionally, the new neutral network, which is expected to be offered by Winity Telecom, using the 700 MHz frequency will be able to leverage mobile network capacity for ISPs. One of the main opportunities for ISPs in the mobile market will be for ISPs to leverage their current broadband customer base with bundle offers combining their existing broadband offering with mobile offerings that utilize the mobile neutral network.

The consequence of this has led to a growing number of strong market participants in the sector. Brazilian ISPs pursing IPOs aim to use the IPO proceeds to strengthen their regional presence across the country. In July 2021 alone, three of Brazil’s largest ISPs, Desktop, Unifique and Brisanet, staged their IPOs. Shares of the companies were listed on the B3 stock exchange in São Paulo. The wave of Brazilian ISP capital markets and M&A activity reinforces the companies' expansion plans, with regional providers continuing to add new acquisitions to their post-IPO portfolio by acquiring smaller ISPS to complement their existing footprint. Other groups are undertaking this same strategy, for example Grupo Vero, Grupo Conexão, Grupo EB Capital, and Grupo mhnet.

Our Business

We are a telecommunications company that offers mobile voice and data services, broadband Internet access, Value-Added Services, and other telecommunications services and products. For a breakdown of our total net operating revenue by category of activity, see—Item 5. Operating and Financial Review and Prospects—Results of Operations for the Year Ended December 31, 2021 Compared to the Year Ended December 31, 2020.

TIM is recognized for its strong brand and for its reputation as an innovative and disruptive company capable of setting new consumption standards for the market. Our proactive approach allows the Company to be in a leading position in the transformation of the telecommunications business model. The change in consumer profiles and the emergence of new technologies foster a rupture in the telecommunications industry based on the consumption of digital data, content and services.

The Company is characterized by its pioneering and innovative offerings, among a complete portfolio for individuals as well as corporate solutions for small, medium and large companies. Besides traditional voice and data services, TIM offers a fixed-line ultra-broadband service, TIM Live, WTTx technology through Ultrafibra service, and is starting to offer IoT solutions, with successful examples in agribusiness.

The Company also offers a variety of digital content and services in its portfolio of packages, increasing for its clients the day-to-day functionality of their mobile devices. The ability to manage a complete and varied portfolio gives TIM the possibility to offer customized packages to its customers and to provide offers bundling services, like voice and data, to customers in certain regions.

In 2021, TIM maintained a position as a competitive player in the postpaid segment, with “TIM Black” tariff plans, providing a better service usage experience and continuously innovating offerings, which have differentials like data rollover and international roaming (data package for use in the Americas). The biggest 2020 postpaid launch was the “new TIM Black Família”, with innovative flexible bundle for streaming subscription where the customer can choose between Netflix, HBO GO or YouTube Premium in their plan. We’ve also included a new data package for international roaming to use in the Americas, a better customer service with new channels available for customers such as voice message in WhatsApp and the option to schedule customer service in store, and a new app experience with an online store where customers can buy premium streaming services, like a “one-stop-shop”. We also made innovations in our portfolio of control and prepaid offerings. In the control segment, which tends to be a gateway to postpaid plans, we were the first to offer a new tariff plan, the TIM Social Networks Control plan (TIM Controle Redes Sociais), with unlimited access to social networks, unlimited calls to any operator, plus data and digital services packages. We believe we continue to be a valued leader in the prepaid plan segment and to offer innovative and complete packages, aiming to increase loyalty among our customer base.

In July , 2019, the Company and Telefônica Brasil also entered into a memorandum of understanding (the “Vivo MoU”), to start negotiations regarding: (i) sharing of a single-grid 2G network; (ii) establishment of new infrastructure sharing agreements for the 4G network in 700Mhz, directed to cities with fewer than 30,000 inhabitants, which in the future may be expanded to larger cities; (iii) other network sharing opportunities in other frequencies and technologies; and (iv) other opportunities in efficiency and cost reduction in operations and network maintenance. We believe that implementing the concepts set forth in the Vivo MoU will result in synergies and efficiencies that could help support us in continuing to provide innovative and standard-setting offerings and services, as well as synergies and efficiencies in the allocation of investments and operating costs.

In March 2020, the Company and C6 Bank concluded negotiations regarding a strategic partnership with the objective of developing bundle offers with special benefits for each of their respective customer bases, combining in an innovative manner digital banking and telecommunications services. The agreement also provides for the possibility of exploring sales and payment channel synergies, expanding the distribution of offers and optimizing costs. This agreement does not create a joint venture. In October 2021, TIM obtained the right to exercise the fourth tranche of its subscription bonus for indirect equity participation in C6’s capital stock, as a result of achieving the fourth level of the agreed targets. As a result, TIM has the right to acquire the equivalent to accumulated indirect equity participation in C6 Bank of approximately 4.08%.

In July 2021, the Company, jointly with Anhanguera Educacional, a subsidiary of Cogna Educação S.A., concluded negotiations regarding a strategic partnership. The objective of the partnership is to combine and develop bundle offers with benefits which aim to make distance education more accessible through the Ampli platform – a digital learning platform developed in a mobile-first concept, by bundling it with the largest 4G network infrastructure in Brazil. Our entry into the partnership is aligned with our customer platform strategy that we have been working on since 2020. This strategy seeks to monetize the assets that we hold as a mobile operator through strategic partnerships that create value for both our customers and our business. This agreement does not create a joint venture and, therefore, we maintain the independence of own operations. Through a compensation mechanism based on objectives and depending on the financial results of the partnership, we will become a minority shareholder of a new company incorporated as part of this strategic partnership. This equity interest could reach up to 30% of the new company’s capital. The subscription for any such capital will require prior approval of Brazil’s competition regulator, CADE.

In line with our consumer strategy platform, TIM will continue to pursue opportunities in other fast growing segments to develop additional partnerships.

TIM seeks to follow the desire of its consumers, considering them at the center of the Company’s decision making, based on: (i) innovation, which is in the DNA of the Company and will continue as a priority, with new plans, offers, partnerships and technologies; (ii) quality, which is the basis for acquiring the customer’s loyalty and for the expansion of its life cycle; and in the (iii) user experience, which is the strategic pillar of convergence of all others, establishing a new relationship with customers and acting in a way that everyone receives the best experience, great services and a transparent relationship with the Company.

Competitive Strengths

We believe that our robust network infrastructure, our innovative approach, our brand recognition and our widespread sales network, position us well to capitalize on opportunities in the telecommunications industry in Brazil and meet the constantly changing demands of the mobile telecommunications market. We believe that our main strengths include:

High quality services

Since national coverage and quality had improved quite substantially over the last few years, Anatel also has shifted its focus. The prior focus was service quality from a broader, state-oriented perspective and now, Anatel is taking a local perspective, concentrating its efforts on smaller geographic areas like cities, especially those where service is still considered poor. In the final quarter of 2017, Anatel proposed the Quality of Telecommunications Services Regulation (Regulamento de Qualidade dos Serviços de Telecomunicações) (“RQUAL”), which, following public consultation No. 29/2017, was approved in December 2019 (Resolution No. 717/2019) and is expected to enter into force in 2022. RQUAL is based on responsive regulation and will apply to all telecommunication services (mobile, fixed, fixed broadband and payTV) on a municipal level and sets forth new obligations for service providers, such as a user compensation model and a mandatory ombudsman, and grants customers additional rights including the customer’s possibility of terminating their service agreement without penalty in case of poor service quality. For more information on the new quality regulation, see “—Regulation of the Brazilian Telecommunications Industry—Quality Management Regulation.”

Accordingly, TIM has also started tracking its quality indicators and focusing on service quality at the city level, in order to assure an even more rigorous review of the customer experience. Following the contribution period, TIM continues to monitor municipalities outside the Anatel threshold (“critical”) and has already started simulating the new indicators set forth in Resolution No. 717/2019.

The results of this local focus are demonstrated in the solid improvements of Anatel’s quality metrics over the last years. As a highlight, the Company has been able to maintain positive results in 3G/4G data-related indicators due to the rapid expansion of our coverage, in particular in 4G, where we are the leading telecommunications company by number of cities covered, according to the Anatel website (www.anatel.gov.br). Anatel’s latest release, which includes data up to the third quarter of 2019, indicates that TIM was the company with the lowest number of critical municipalities.

TIM also demonstrated a strong performance of its LTE technology in data usage, wide coverage and availability. The TIM 4G network received higher measurements, when viewed against other test of 4G networks, in the Brazilian market on the SpeedTest platform. These results are important given the strong demand by TIM customers for this technology in 2020. At the end of 2021, approximately 90% of TIM’s data traffic was carried out by the 4G network, up by 5 p.p. when compared to the previous year.

It is also worth mentioning that the results of digital transformation initiatives continue to expand and, during 2021, presented solid results. Given the impacts of the COVID-19 pandemic, society demanded even more network capacity and digital solutions. This demand meets the strategy TIM has adopted for several years to seek digital evolution and the constant network development, aiming to ensure innovative solutions, quality and availability of services, offering a superior customer experience and strengthening the Company’s positioning in the market. We believe that the digital transformation of our services must take place on several fronts, from the sale and activation

of the line, to post-sale and the so-called “self-caring”, meaning the digital service portals that allow customers to manage profiles and subscriptions, billing, collection, and payment.

Even in a challenging year, our digital channels’ positive results and the excellence of services offered to our customers confirm the business decisions made during such period were appropriate, prove our capacity to adapt to adverse situations and, reinforce our purpose of “evolving together, with courage, transforming technology into freedom”.

Customer service is one particular area in which digitalization – in particular our Mobile App and interactive voice response (“IVR”), technology – has proven fundamental to improving the customer experience. In 2021, our digital customer interactions increased by 2.83% ( a decrease of 4.66 % in Mobile App and Website interactions partially set off by a decrease of 25.1% in IVR interactions). Additionally, the number of individual users of the “Meu TIM” application in 2021 grew 9.08%, while IVR retention increased by 0.3 percentage points. Also, digital sales in the postpaid segment increased by 9.7 % in the year ended December 31, 2021 as compared to the year ended December 31, 2020, while recharging by digital means continues to become a more relevant sales channel, with a 41,2 % increase in the year ended December 31, 2021 as compared to the year ended December 31, 2020.

We believe our ultra-broadband service is also viewed generally as a reference of quality in the sector, driven by our commitment to the customer experience. This service quality of TIM Live has demonstrated itself to be excellent, as recognized for 6 years in a row (2015 - 2021) by the sixth time by the widely circulated newspaper, “O Estado de São Paulo.”

We also seek a strong position in the high-value customer market as a content HUB by offering a variety of plans for individual and family usage, bundling voice and data packages, streaming and other content subscriptions, as well digital Value-Added Services (music, e-reading, video streaming, games), in order to provide a custom customer experience.

We are also better able to provide high quality services due to our strong relationship with our suppliers. We operate a system for information technology vendor management in order to improve the commitment of our suppliers. As a result of this approach, we benefit from enhancements like (i) better accountability of end-to-end vendors on our business processes; (ii) better contractual conditions and savings due to the increase of volumes per vendor; (iii) vendor consolidation and specialization in specific platforms/processes, creating the opportunity for long-term investments in such areas; and (iv) active contribution to transformation and simplification and (v) raising the best practices of Request for Quotation instead of Direct negotiating in order to gain more savings, also increasing the so called Global Deal among the Company and Telecom Italia with the scope to capture more synergies and quality of the furniture’s by global vendors.

These processes were organized and improved through detailed rules such as the Projects Review Board and Investments, and the Function Points Productivity Contractual Auditing. This allowed us to achieve an excellent level of information technology governance, exemplified by better business contribution of each investment due to shared objectives and goals. As a result, we improved our efficacy and efficiency.

Finally, we also continue to seek new internal data sources in order to better understand our users’ perspective and needs, including collecting and analyzing information from applications and investing in the modernization of traditional quality-assessment tools.

The Company understands that the above statistics reflect its commitment to solid infrastructure and its focus on the customer experience. However, the Company recognizes that there are some statistics and/or quality measures that use different methodologies that could present diverse results from those that are mentioned above.

Open Innovation Program

TIM’s Open Innovation Program has the objective to establish a network to exchange knowledge, best practices and business models within a collaborative group of enterprises, startups and academia in order to leverage the development of innovative products and services. The program focuses on learning and exploring new technologies in partnership with complementary business partners, in order to create sustainable and responsible solutions. The

collaboration network is based on the concept of partnerships with startup, innovation hubs, academy and/or society, and is designed to bring together entrepreneurs, vendors, technology companies, providers and content developers, innovation centers and universities so that they can recognize in TIM a potential partner in the development of new products, services or business models based on TIM’s business strengths and technology.

A supporter of the open innovation concept for five years, TIM has been obtaining good results from such approach to business. After a unique year in 2019 for TIM’s Open Innovation program, when the company became a space for promoting and fostering a new technological wave in Brazil, TIM went further in 2020 and 2021, increasing its involvement with startups, establishing new partnerships with innovation hubs dedicated to healthtechs and agritechs. During 2019, TIM established 5G Living Labs with the aim to foster the development and use of 5G in a variety of contexts, to perform network testing and promote market readiness. The 5G Living Labs establish an environment for experimentation and co-creation in which end-users, researchers, companies and public institutions explore, design and jointly assess new and innovative products, services, solutions and business models, and provide important feedback for development and subsequent commercialization of products and services. In this occasion, four labs were launched with national and international partners across Brazil: one with the Federal University of Santa Catarina and CERTI Foundation, one with the National Telecommunication Institute (Inatel) in Santa Rita do Sapucai (State of Minas Gerais), one with the Federal University of Campina Grande and Virtus Institute and one in São Paulo within CUBO, the most prestigious startup hub in Latin America. These TIM 5G Living Labs focused on fostering 5G use in the following areas and business sectors: telemedicine, remote education, smartcity, security, intelligent home, game streaming, drones, industry 4.0, immersive technologies for education, health, industry and entertainment (actual reality and virtual reality) and smart agriculture using experimental 5G radiofrequencies.

In 2020, TIM, together with the Telecom Infra Project (TIP) and the National Telecommunication Institute (Inatel) started the Open Field Program, which aims to develop innovative and sustainable solutions for the expansion of the radio access network (RAN) infrastructure, creating an adequate environment to run tests, like a living laboratory, validating and accelerating products and new functionalities of open and disaggregated technologies solutions, such as Open RAN. The program has taken place since 2021.

In 2021, as part of our client platform strategy for start-ups, we actively pursued a number of fintechs, edutechs, insurtechs and healtechs, among other verticals in an effort to transform those startups into unicorns. This was based on our client platform strategy pursuant to which we seek partnerships with digital service companies where we believe we can accelerate their growth and create new business models, client journeys and marketing approaches. As part of this strategy, we started pilot projects to foster the development of an ecosystem of solutions and partners with the aim to approve devices and applications in partnership with academies, government agencies, communities and startups.

TIM, in alliance with Inatel – Brazil’s National Institute of Telecommunications, will develop use cases regarding internet-of-things (IoT) and smart cities based on IoT Mobile solutions with applications that could improve the quality of life of citizens, development of intelligent tools and enable new processes of public administration.

TIM in alliance with PUC/Rio - Pontifical Catholic University of Rio de Janeiro, will develop different use cases in relation to following verticals:

(i)       Health:

•       Patient monitoring, both remotely and in healthcare facilities: cost-effectiveness study of clinical outcomes among patients using the IoT solution and control groups

•       Monitoring of assets, supplies and resources in health facilities: cost-benefit assessments of using the IoT solutions.

(ii)       Rural:

Efficient use of natural resources and materials, with an emphasis on meteorological and soil monitoring, in order to promote increased productivity as well as cost reduction.

•       Efficient use of machinery with an emphasis on machine performance management, with the aim of optimizing the use of equipment.

In 2021, with the aim of redefining smart cities in Brazil and exploring the full potential of 5G, TIM, Enel X Brazil and Leonardo Brazil joined forces to serve Smart, Safe and Resilient Cities. The companies agreed to offer and develop joint solutions for smart cities, combining experience in energy, telecommunications, technology, and cybersecurity tailored to Brazilian municipalities.

In 2021, TIM became a partner of Embrapa, the main agent of innovation and research in agribusiness in Brazil and the world, in the development of a new innovation agribusiness hub called Silo, located in Juiz de Fora (MG). The hub pursues innovative solutions through the combination of entrepreneurship, research and innovation. TIM will have a relevant role in the hub, enabling mobility and 5G.

In 2021, in relation to 5G, TIM, in partnership with AgTech Garage innovation hub, launched a call for startups that want to evolve or pivot their business plans in order to utilize 5G. The call was successful, having more than 45 startups registered, with eight finalists. Those startups had the opportunity to present their pitch to us, involving solutions for fire detection, irrigation, intelligent fertilization, robotics, image monitoring, pest control, among others. Among the finalists, four startups were selected to test and evolve their minimum viable product (MVP) together with Auros Robotics, Quickium and Umgrauemeio.

In 2021, driven by current market trends and the role of 5G enabling new business concepts, we established a partnership with Intel, which allows us to have first-hand access to Intel technology. The project focuses on offering 5G network services to benefit end consumers. The focus of the partnership is mainly on cloud gaming and the metaverse. This initiative is unprecedented in the Brazilian market, making us the first pioneer partner of Intel for cloud gaming over 5G.

In 2021, we again took part in the biggest hackathon in Latin America, Hacking.Rio. The challenges were based on the UN Sustainable Development Goals and we launched a challenge based on SDG 11 – “Sustainable Cities and Communities”, looking for products and services that can benefit mobility and help create, more modern and cleaner cities with green spaces.

In 2021, Stellantis, TIM and Accenture teamed up to launch the first standalone 5G pilot for the automotive industry in Brazil applied through a private network, which uses artificial intelligence and cloud computing.

In 2021, we were chosen as the telecommunications provider responsible for providing the 5G infrastructure and network, deploying the 5G SA (standalone) network core in the public cloud, constituting an integrated digital environment

A Strong brand with a new tagline.

During the 2020/2021 COVID-19 pandemic, telecommunications services were very important, as connectivity allowed people to find new ways of studying, working and finding entertainment, making the world even more digital. TIM translated this trend into its new brand tagline, “Imagine the possibilities”, which invites customers to see the future in a positive way and shows that TIM will be next to them in their new challenges, opening a world of opportunities. In addition, TIM presented a new spokesperson representing the current brand values - freedom, respect and courage - and highlighting diversity, a relevant pillar in the company’s strategy. To reinforce its brand strategy, TIM made a new reading of its purpose: “Evolve together with courage, transforming technology into freedom”, indicating that the company will continue to lead important market movements and act as a pioneer in customer services. Furthermore, to reinforce the brand image, a new campaign was launched to communicate TIM network quality, “TIM network. You can count on.”, that shows the evolution of 4G technologies, in which TIM has the largest coverage in the country since 2015, in addition to highlighting the 4.5G and the new 5G DSS. Finally, in order to help reinforce our brand association with music, in December 2021 we announced our sponsorship of

certain music events in 2022.. This included a sponsorship of the 2022 Brazilian edition of the Rock in Rio festival and TIM Music Verão (free concerts on the beaches of Rio de Janeiro).

Advanced Technology and Innovation Center

In 2017, we set up TIM Lab, a multifunctional test bed environment for evaluation of innovative technologies, products and services, assessing their functional efficiency and performance requirements, and development of new models and solutions. This endeavor brings engineers, researchers and technicians together to ensure effective assessment, and serves as an open space for new opportunities, leading innovation for the Brazilian telecommunications market and acting as a national reference for R&D activities.

TIM Lab performs a strategic role in supporting service assessment and innovation activities. These projects support TIM’s network evolution and tackle certain important business and market needs, including the evaluation of new generation networks, future Internet applications, projects with positive social and environmental impacts and open innovation initiatives.

In this sense, TIM has also joined the Telecom Infra Project (“TIP”), an initiative founded by Facebook and other companies to create a new approach for building and deploying telecommunication network infrastructure, with TIM Lab as the first TIP Community Lab in Latin America. In addition, since 2017 TIM Lab has also participated as one of the GSMA Mobile IoT Open Labs since 2017, a community where companies developing solutions over cellular low power wide area networks can work with experts on their projects.

Among the technologies assessed and approved at the TIM Lab environment are certain extremely important technologies to support the network evolution, including 700MHz LTE, IP multimedia networks (voice over LTE, video over LTE, WiFi calling services, completely laid out functional blocks, and enabled by an IP multimedia subsystem platform), network functions virtualization (“NFV”), 4G RAN sharing, NB-IoT, Defense Wavelength Division Multiplexing, transport network and power saving features and solutions. In 2019, TIM launched its nationwide 4G NB-IoT network in 700MHz, covering over 3,200 cities. In 2020, TIM ran laboratory tests and live trials with 4G advanced features combined with 5G (multiple antennas plus carrier aggregation and dynamic spectrum sharing). The first 5G NSA compatible devices were homologated and commercialized in 2020, allowing the users to make use of the technology in the available live clusters. Open-RAN solutions were also evaluated in laboratory environment with the objective to assess the maturity of 4G and 5G disaggregated solutions for future field trials. Other advanced technologies, such as edge computing, disaggregated transponders and transport network optimization and automation solutions were also evaluated in TIM Lab in 2020.

TIM evaluated 5G standalone architecture and solutions in 2021 (known as 5G SA), for commercial deployment in 2022. Also in 2021, TIM developed proofs of concept (PoCs) making use of different technologies associated with 5G SA, such as artificial intelligence for the automated processing of images (using 5G as mean of connectivity), and cloud software for hosting 5G core network elements.

Strong commitment with ESG pillars and the only Brazilian telecommunications company listed on the Novo Mercado for over 10 years

Since TIM Participações’s listing on the Novo Mercado in July 2011, we are the only company in the Brazilian telecommunications sector listed on this segment of the B3 for over 10 years. As part of our listing on the Novo Mercado, we are required to comply with heightened requirements relating to corporate governance and the disclosure of information to the market. As part of our strong commitment to these principles, we made our financial results meetings available by teleconference, smartphones and tablets, in addition to computers. We believe that the listing on the Novo Mercado provides greater liquidity and value for our shares and allows us greater access to international markets, promotes the strengthening of our corporate image and increases confidence in us, in addition to reaffirming the long-term commitment of Telecom Italia and its subsidiaries (the “Telecom Italia Group”), in Brazil. We believe listing on the Novo Mercado also aligns the interests among our controlling and minority shareholders with respect to voting rights, tag along rights and dividend policy.

In addition, we belong to a select group of companies comprising the portfolio of the Corporate Governance Index and the B3 Tag Along Stock Index, comprised of companies that have committed to adopt better co-sale

protection to minority shareholders, have actively traded in 30% of the trading sessions and do not constitute a penny stock. In December 2021, despite methodology changes made by B3 to enhance the index rigidity, we were listed for the fourteenth consecutive year as part of the portfolio of the Corporate Sustainability Index of the B3, an index comprised of companies that have a strong commitment to sustainability and social responsibility. In 2021, we also remained one of the constituents of the S&P B3 Brazil ESG Index. In January 2022, we were selected to remain in the portfolio of the Carbon Efficient Index, or ICO2, of the B3, with the commitment to measure, disclose and monitor its greenhouse gases, or GHG, emissions. We increased, by 24%, our S&P ESG Score, which is based on our response to the Corporate Sustainability Assessment (CSA). We believe that our improvement in ESG performance was one of the highest in the international telecommunications industry. The constant pursuit of best environmental, social and governance practices also ensures our presence in several international indexes and ratings, such as FTSE4GOOD Emerging Markets, FTSE4GOOD Latin America, MSCI AWCI ESG Leaders, MSCI Emerging Markets ESG Leaders, Refinitiv D&I Index, among others. In 2022, the organization responsible for the Dow Jones Sustainability Index (DJSI) was considered one of the busiest companies in the world. The company was awarded its DJSI22 for the performance evolution in its submission process of 24.2%.

TIM is the first Brazilian operator to be part of the 2021 Refinitiv Diversity & Inclusion Index, which measures the performance of more than 11,000 companies - equivalent to 80% of the global market - based on diversity, inclusion and career development initiatives. Ranked 19th in the global ranking, TIM leads the list of companies in the telecommunications sector worldwide and is also the benchmark in Brazil, considering all sectors.

As a signatory to the Global Compact since 2008 and UN Women since 2021, TIM promotes projects related to the Sustainable Development Goals (“SDG”) and recognizes the rights to data privacy, safe internet, access to information and freedom of expression as essential and unnegotiable as part of its efforts to respect Human Rights.

As part of its commitment to society in addressing climate change, TIM conducts periodic mapping of the sources of emissions in its activities. The Company is able to do so by preparing annually a GHG inventory in accordance with the guidelines of the GHG Protocol (which sets the global standard for how to measure, manage, and report greenhouse gas emissions) and is working with TIM in Italy to establish goals aligned with the Science Based Targets Initiative (SBTi), since TIM Group joined the initiative in July 2021 with the challenge of keeping global warming limited to 1.5°C, as established in the Paris Agreement. The SBTi aims to promote the best reduction and offsetting GHG emissions in line with climate science. Since 2010 TIM reports its greenhouse gases (GHG) emissions by means of the Carbon Disclosure Project (“CDP”) – the largest database of primary corporate climate change information in the world – and publishes its GHG emissions inventory in accordance with the Brazil GHG Protocol Program. In 2021 the CDP questionnaire was integrated by B3 as a crucial part of the methodology for the selection of the constituents of the Corporate Sustainability Index and our CDP Score improved from B- to B. In 2020, the ICDPR70 was launched, an exclusive Index that includes companies publicly committed to reducing their carbon footprint, tracked by companies' scores on the CDP questionnaire and classifying those with the best level of awareness of climate change. TIM has been included on this index. Another highlight in 2021 was the recognition as seventh place in the ranking of the consultancy Resulting, an office specialized in ESG integration, research and education for planning and risk analysis.

We also identify opportunities to improve our levels of excellence in our Environmental Management System (EMS), covering all our operations, based on our Environmental Policy. This includes basic commitments such as protecting the environment, customer service to the legal requirements and norms of the organization and the continuous improvement of performance in processes and controls, having obtained the ISO14001 environmental certification for Network Management and Operation in the states of Rio de Janeiro, São Paulo and Espírito Santo.

For 14 years TIM has published its Sustainability Report presenting the main financial and non-financial results, in accordance with the Global Reporting Initiative (“GRI”) Standards methodology. As of 2021, we will refer to this publication as the ESG Report and reinforce our commitment to transparency and accountability to our stakeholders, organizing the report into three pillars: Environmental, Social and Governance. In the 2021 ESG Report, we also started to consider reporting the SASB - Sustainability Accounting Standards Board. The Report has an independent third-party limited assurance since 2009.

Our main policies - such as the Corporate Social Responsibility, Human Rights, Environmental, Climate Change, Supplier Relations, Risk Management, Anti-corruption and Safety & Occupational Health Policies - are publicly available to the consultation of our stakeholders.

Founded in 2013, Instituto TIM has a mission to democratize access to science, technology and innovation, in order to promote human development in Brazil. More than 700,000 people from all Brazilian states and the Federal District have been benefited by the education and inclusion projects of Instituto TIM, some of which were internationally awarded (i.e. Governarte Awards – BID 2015). More on Instituto TIM’s actions on the website https://institutotim.org.br/.

In 2021, we included long-term ESG commitments in our 2021-2023 Strategic Plan. Based on the ambitions assumed in the last Industrial Plan (2020-2022), we included new objectives related to a portfolio of initiatives that are part of our business strategy, contributing to a coherent interrelated structure between ESG aspects, business operations and organizational accountability. For the TIM Group, the business role is increasingly tied to the responsible management of aspects that go beyond financial targets and aim to generate positive value for society in the long term.

Among the established goals, our environmental pillar is to become a carbon-neutral company by 2030. In addition, we have undertaken to achieve by 2025 90% of energy consumption being from renewable sources, to increase by 80% the energy efficiency in data traffic (against the base year of 2019), to reduce by 70% indirect emissions and to recycle at least 95% of our solid waste. From a social perspective, the main commitments are for our workforce to be comprised of 40% of black people, our leadership positions to be comprised 35% of women, to take 4G connectivity to all Brazilian cities, and to keep our level of employee engagement of at least 80% until 2023. The Company obtained the ISO 37001 (anti-bribery management systems) and aims to obtain, until 2022, the ISO 27001 (information security management), both are important aspects of our Corporate Governance pillar, which also has as goals, by 2022, to keep TIM on the Novo Mercado, Pró-Ética and ISE-B3, and the ISO 14001 and ISO 9001 certifications. Our ESG plan is annually updated together with strategic plan.

Highly qualified and experienced executives and controlling shareholder support.

We have a team of highly qualified executives, widely recognized in the industry and possessing extensive experience in telecommunications markets in Europe and emerging countries. Our executive compensation policy seeks to align the interests of our executives with those of our shareholders, through variable compensation plans and share based incentives that reward good performance and the accomplishment of certain goals, as well as provide for improved executive retention.

Our controlling shareholder’s support in our operations is further demonstrated through the sharing of know-how and best practices and development of new solutions for networking, marketing and finance, which are rapidly rolled out under a “plug & play” strategy, under which network innovations may be developed by our parent company first in other regions and then implemented with us.

Strong financial position

With consistent financial results in recent years, and solid earnings before financial income (expenses) (including foreign exchange variations), income tax and social contribution, depreciation and amortization costs and expenses and share of loss of an associate (“Adjusted EBITDA”), according to our internal analysis, we believe that we have a strong cash flow generation, a solid financial position and a low relative Net Debt to Adjusted EBITDA ratio. In this scenario, we understand that we are in a strong position to take a significant role in potential future consolidations in the market and/or to have a competitive position in important frequency auctions in the years to come.

Our Strategy

Our Strategic Plan

We expect our updated strategic plan to allow us to consolidate the TIM brand through 2024, in a consistent approach with our prior plan (2021-2023). Our new plan is focused on our main stakeholders and on providing building blocks for our future growth by combining evolution and transformation to develop our strategic pillars.

We believe that, during the next years, some relevant trends, such as mobile market consolidation, wave of asset separation, acceleration in digital consumption, 5G, such as the Internet of things, or IoT, and the machine-to-machine market, or M2M, technology, will have structural implications on the business model of telecommunication operators in Brazil, including the uncertain pace of the country’s economic recovery.

After a long and intense journey of development and transformation, we are now paving the way to become the Next Generation Telco by strengthening our core and accelerating growth beyond connectivity, closing the gap on the core (e.g. spectrum, CX) and becoming the best telco in Brazil.

In order to strengthen our core in the provision of mobile services, our plan is build and retain our customer base with an ever improving service quality and value proposition, while in relation to our provision of fixed services our plan is to attract and retain customers by improving operations and expanding our coverage.

In order to accelerate growth beyond connectivity our plan is scale up partnerships leveraging base and key assets to expand new businesses and exploit new business opportunities through separate entities (spin-offs).

Our forward-looking strategy is focused on the three strategic key priorities:

In our view, the COVID-19 pandemic increased demand for connectivity and the telecommunications sector benefited from this context. As a result, we believe we can be considered a more resilient company, not only due to data consumption growth, but because we have been honing our market vision and execution capacity to create long-term value.

Protecting the value of our prepaid customer base and aiming at the growing postpaid segment, shifting focus from absolute market share to revenue share, and strengthening our existing customer base.

Up until 2020, the Brazilian mobile telecommunications market was facing an overall reduction in the number of prepaid customers. However, in 2021, the prepaid base increased, which may be a consequence of the socio-economic changes in population or particular incentives in our competitors’ offerings. It is not yet possible for us to confirm whether this indicates a trend reversal or just a brief pullback. We maintained our strategy to be chosen as the single SIM provider for the prepaid consumer market by providing offers that are attractive and valuable to customers while maintaining our reputation for quality and innovation. For the prepaid consumer market, our key priority is to offer simplification to improve customer experience with continued evolution of digital channels, while for the postpaid consumer market, our plan is to grow based on a “Mobile Challenger” approach pushing migration from prepaid, leveraging the benefits of 4G coverage leadership and establishing a customer long-term relationship driven by loyalty initiatives. To support this strategy, we also implemented new offers, new handset strategy and initiatives in our sales channel model because of the pandemic. We improved the digital channel and created a drive thru and delivery sales models experience.

Since the beginning of the pandemic, in order to contain the negative impact of the crisis, numerous actions were taken, highlighting the encouragement to recharge by means of digital channels and the digitalization of Control customers who paid their bills in physical channels, reducing bad debt.

In the business to business market, we intend to leverage consumer offers and channels in order to gain market share in the small and medium business, or SMB, segment, as well as to launch a new mobile offering focused on micro and small businesses. We are also pursuing the development of targeted markets such as the Internet of things, or IoT, and the machine-to-machine market, or M2M, beyond simple connectivity, and evaluating business opportunities for the application, using the 5G network, of mobile application and fixed wireless access. Moreover, we are repositioning our sales channel strategy in order to increase not only efficiency but also sales productivity. Our growth strategy is mainly focused on addressing the potential for mobile Internet in the Brazilian market, particularly increasing mobile Internet penetration and data traffic. We believe mobile operators are in a strong position to address the demand for broadband in Brazil, with the ability to provide flexible price plans affordable to the majority of the Brazilian population. The lack of fixed infrastructure is still an issue for accessibility to fixed broadband, especially in suburban areas, making mobile coverage more suitable for such customers without broadband access. In addition to providing affordability and coverage advantages, mobile operators appeal to the new cultural demand for Internet connectivity at all times and in all places.

In addition, our strategy also involves positioning TIM as a partner of our existing customer base, by increasing their loyalty by offering exclusive products to existing customers, focusing on Value-Added Services in our offers, and by differentiation in our products and services. Value-Added Services represent an important part of the TIM strategy, as it is already a relevant market and has high growth rates with the potential to increase revenue streams. Such services are generally launched through a partnership with an established OTT player. We believe the foregoing strategies will allow us to strengthen customer loyalty without requiring us to incur higher costs, as increased traffic within our own network does not significantly increase our operational costs. We are also investing in new channels, to bring new customers to the company and to enhance each customer’s experience. We are constantly seeking new customers through new marketing efforts and promotional initiatives. Another important growth factor is expected to come from our digital strategy evolution, with an increased role in the growing M2M and IoT ecosystem, exploring new revenues opportunities including being more than just a connectivity provider, offering a platform (analytics, big data, mobile advertising, etc.) and a content offer aggregation to support mobile and fixed service revenue growth. Capitalizing on fixed-mobile substitution in voice and traditional services.

We seek to capitalize on the existing opportunity of fixed-mobile substitution in voice and data traffic and encourage the use of mobile devices, rather than landlines, for long distance communication and Internet. We believe that the main advantage of our product offerings is that our customers are able to use our growing mobile network.

In the voice market, this strategy has been successful in part due to the limited service offerings of other long distance carriers in Brazil and the acceleration of fixed-mobile substitution. We have become a market leader in long-distance telecommunications, based on our market share. Fixed-mobile substitution is still evident in Brazilian

market, as fixed telephony operators have experienced declining revenues. Since we are primarily a mobile operator with robust network infrastructure, the impact of any reduction in the fixed telephony market does not have a material impact on our performance, and we therefore encourage the acceleration of fixed-mobile substitution, which in turn increases demand for our services.

As already mentioned, TIM is also targeting the residential broadband market through its 4G mobile broadband network, using fixed wireless access technology, connecting homes to the Internet by using a router that connects to our 4G mobile network. We believe such product can be suitable especially for areas with poor fixed broadband infrastructure as our 4G coverage is growing rapidly. We are also evaluating the use of the 5G network to provide fixed wireless access solutions.

Providing Internet access to everyone.

We intend to provide universal Internet access to an increasing number of individuals, offering our prepaid and postpaid customers competitive data usage plans through wireless handsets or other data devices (e.g., tablets, wearables, etc.). Our focus on increased data usage among our customers is also influenced by our ability to effectively manage our handset and accessories sales, with a focus on entry level 5G smartphone models that will be ready for the deployment of our 5G network, providing quality Internet access. This approach is allowing us to offer our services at a highly competitive price, offer convenient payment methods, meet market demand and allow for opportunities for innovation. The result of this strategy can be seen in the increase in our number of data users and in smartphone penetration, especially in 5G. Leading mobile Internet growth in our sector is a key pillar of our strategy, since we see this as the most important market in terms of growth and size in the foreseeable future. Our marketing efforts have also been designed to stimulate Internet usage and leverage our 4G and 5G networks by providing for suitable and affordable postpaid and prepaid Internet plans.

Construction of a unique infrastructure network in the Brazilian market and improving our network

We are committed to developing a robust network infrastructure capable of serving our customer base and anticipating new trends and technologies in the industry. The development of this infrastructure requires both organic (planning and infrastructure development projects for the existing network) and inorganic (acquisitions) investments. As part of our strategy to focus our investments in infrastructure, TIM Participações acquired Intelig (now known as TIM S.A.) in December 2009, in order to establish TIM’s own fiber optic network and develop automation projects. TIM Participações also acquired the company formerly known as AES Atimus (later TIM Fiber, which was merged into TIM Celular in 2012, and TIM Celular was merged into the Company in 2018) in 2011 to strengthen and expand our fiber optic network. With the acquisition of Oi’s mobile operations, TIM will improve its market position, capturing higher gains of scale, synergies and optimizing investments. TIM should incorporate approximately 7,200 mobile access sites, which corresponds to 49% of the total sites of Oi’s mobile assets unit.

Besides improving our core infrastructure, TIM has been rolling out an aggressive plan for 4G coverage, which has placed TIM as the undisputed leader in 4G coverage in Brazil, achieving more than 4,715 cities with 4G technology at the end of 2021, considerably ahead of its competitors. This positions TIM as having the best overage and the best mobile broadband technology. We were elected the telco with the best “video and video calling experience” and with the most available 4G coverage by OpenSignal, in partnership with Anatel. We have also reinforced our commitment to cover 100% of the country with its 4G network by 2023. Moreover, we have also been strategically expanding the 700 MHz frequency, which now covers 3,975 cities, and the 4.5G coverage to 1,712 cities by the end of December. In order to improve our network coverage in an efficient way, we have expanded our “Single Grid Coverage” (a network agreement with Vivo reaching more than 353 cities implemented by TIM and 363 by Vivo, already with consolidation tests in 21 cities) and the Sky Coverage project (924 sites connected via satellite). We have also undertaken investments in network modernization, including more than 1,600 sites with M-MIMO (Massive Multiple-Input Multiple-Output) in 2021.

Expansion into new businesses and continued strength in recently expanded sectors.

TIM Live offers high quality ultra-broadband, with high-speed data connection. Despite limited access to new markets, FTTH (fiber to the home) network coverage continued to grow, prioritizing the consolidation of already

active clusters. We ended 2021 with growth of 29.0% YoY of total homes passed (HPs) with fiber, operating in 28 cities and 7 administrative regions of the Federal District, and with an ARPU increasing by 3.7% when compared to 2020.

TIM Live ended 2021 with 685,000 connections, adding approximately 40,000 lines in the past 12 months, up 6.1% YoY, maintaining its growth trajectory, with the FTTH base as the main lever. Higher value plans, with speed above 100 Mpbs, continue to gain more relevance, reaching a 62% share of the total base in the quarter ended December 31, 2021. We plan to continue expanding TIM Live's services with the coverage rollout model transition from building to renting, with I-Systems acting as one of the infrastructure vehicles with the mission of deploying, operating and maintaining last-mile infrastructure for broadband access, in a strategy of changing capex to opex with positive free cash flow impact.

Since 2020, TIM has been developing an innovative customer platform strategy that aims to monetize our customer base. Commercial partnerships with direct compensation for sales of advertising and data intelligence yielded revenues of approximately R$36 million in 2021. Meanwhile, strategic partnerships like our partnership with C6 ended the fourth quarter of 2021 with a record number of active accounts, helping us to reach an equity interest of 4.08%. In terms of revenues, the partnership generated more than R$83 million for TIM in 2021. Similar to our partnership with C6, we also established another strategic partnership with Cogna, for distance learning through the Ampli platform, reaching over 50,000 users enrolled in undergraduate courses and open courses in 2021.

Sales and Marketing Strategy

Our recent sales and marketing strategy has been characterized by:

Digitalization and innovation by means of a partnership with C6 Bank, a digital bank, that adds more value to postpaid customers, bringing exclusive benefits such as credit card with free annual fees, exclusive investment portfolio, no tax to open an account, subscription of a premium delivery app included “RappiPrime”, and also expanding our telecom benefits with internet bonuses, internet to use in international roaming, international long distance calls and the possibility to buy smartphones with better payment options with C6 Bank credit cards.

A new partnership with Ampli, an educational group in Brazil, that is intended to offer greater value to our postpaid customers by bringing exclusive benefits to TIM Black and TIM Controle. Ampli is a fully digital educational platform created by Kroton and developed to be used primarily on smartphones. TIM and Ampli offer exclusive benefits to customers, such as: six free months on courses, discounts on graduation courses from R$149.99 to R$99.99 and zero rating on navigation.

Mobile Service Rates and Plans

In Brazil, as in most of Latin America, mobile telecommunications service is offered on a “calling party pays” basis, under which the customer generally pays only for outgoing calls. Additional charges apply when a customer receives or places calls while outside the customer’s “registration area,” which are the areas into which we divide our coverage areas.

Under our current authorizations, we are allowed to set prices for our service plans, provided that such amounts do not exceed a specified inflation adjusted cap. Anatel must ratify our basic and other service plans, but its focus is on compliance with the relevant regulatory rules rather than the prices charged. See “—Regulation of the Brazilian Telecommunications Industry—Wholesale Rates Regulation.” We charge different rates for our services, which vary according to the customer’s service plan. Per minute prices decrease as customers commit to purchasing more minutes per month. Prices can also vary depending on the type of call (for example, calls from other operators on fixed lines or calls outside the network for mobile calls) or the location of the parties on a call.

Anatel regulations require mobile telecommunications providers to offer service to all individuals regardless of income level. We recommend service plans that are suitable to each potential customer’s needs and credit history, such as our prepaid service plans described below. If a customer fails to make timely payment, services can be interrupted. See “—Billing and Collection.”

We offer mobile services under a variety of rate plans to meet the needs of different customer classification, including our corporate customers. The rate plans are either postpaid, where the customer is billed monthly for the previous month, or prepaid, where the customer pays in advance for a specified volume of use over a specified period.

Our postpaid plans include the following charges:

Certain plans include the cost of national roaming and long distance in the price per minute so that all calls within Brazil cost the same amount per minute. Some postpaid plans are designed for high- and moderate- usage subscribers, who are typically willing to pay higher monthly fees in exchange for minutes included in the monthly

service charge while other plans are designed to satisfy the more limited needs of low-usage postpaid subscribers. We also offer customized services to our corporate clients, which may include local call rates between employees wherever located in Brazil.

We offer a single prepaid plan with promotional offerings, which does not include monthly charges. Prepaid customers can purchase a prepaid credits plan that may be used for calls, data and additional services, based on the specific customer’s needs. We have agreements with large national retail store chains, in addition to partnerships with regional retail store chains, to offer recharging online. Customers can also recharge straight from their mobile handsets using credit cards.

Consumer Plans

In 2021, we continued to improve our positioning towards high value consumers, offering a variety of plans bundling voice, data packages and free access to certain applications, as well digital Value-Added Services (music, e-reading, video streaming). The approach to this segment is driven by the strategy of adding value for the customer base and ensuring users a premium custom experience.

Within the consumer business, our main plans include:

Prepaid Plans

Postpaid Plans

In the higher value postpaid segment, we have maintained our position in the market as an innovator and disruptor with our new TIM Black Família and TIM Black plans, discussed above, improving our portfolio by offering large shared data packages with monthly video streaming subscriptions, such as Netflix, HBO GO or YouTube Premium already included in the fee.

TIM Black Família plans start at R$199.99 for an entry level plan with unlimited off-network calls, 30 GB shared data package (for one main line and one dependent), and unlimited data for OTT applications such as WhatsApp, Facebook, Instagram and others. The main offer is set at R$319.99 (for one main line and three dependents) with unlimited off-network calls, 100 GB shared data package, Netflix, HBO GO or YouTube Premium monthly fee included, and unlimited data for OTT applications such as WhatsApp, Facebook, Instagram, data rollover, international roaming (including data package for use in the American continent, seven days of unlimited WhatsApp and 30 minutes of voice) and others.

TIM Black plans start at R$109.99 for an entry level plan with unlimited off-network calls, 15 GB data package (for one main line), and unlimited data for OTT applications, such as WhatsApp, Facebook, Instagram and others. The main offer is set at R$149.99 (for one main line) with unlimited off-network calls, 25 GB data package, data rollover and international roaming (data package for use in the American continent) and other benefits like unlimited data for OTT applications and Value-Added Services such as music, e-books and magazines.

Control Plans

Our Control plans are a hybrid between our prepaid and postpaid plans, with fixed price billed to the customer on a monthly basis, either via credit card or digital account. Once customers of Control plans have reached the limit

of their data plan, the data transmission is no longer available and the user has two options: (i) to repurchase a data package or upgrade to higher tariff plan or (ii) to wait for the next data period to commence, which varies by plan, at which point his data availability and usage limit are renewed in full. Postpaid customers can also purchase a data package to navigate in full speed but the usage is not blocked when he reaches the limit of his data package.

TIM Controle plans start at R$44.99 with unlimited on-network calls and 25 minutes of off-network local calls and 2.5 GB Internet. The main offer in the TIM Controle portfolio (which has a commercial focus) is set at R$64.99 with unlimited calls, 4.0 GB Internet and unlimited data for OTT applications.

Corporate Plans

TIM commenced an ambitious endeavor in 2018 to bridge the connectivity gap in Brazilian rural areas in partnership with the agricultural industry. As a leader in 4G coverage, TIM already had agribusiness customers, but sought to enable the digitalization of the industry and to offer innovative solutions in order to increase its productivity with automation, control and new technologies. We joined major companies within the sector to create ConectarAGRO, a customer-focused initiative to expand connectivity to all rural areas of Brazil, increasing productivity and transforming the lives of those who live in these regions. The initiative has reached its 2019 goal of 5 million connected hectares and expects to progress further in 2020.

In 2021, we continued to improve our positioning towards the large companies as potential clients, offering a variety of corporate solutions for mobile or fixed services (both voice and data), as well as Value-Added Services and mobile-to-mobile services. The approach for these top clients are driven by customized solutions and a premium customer service focus. In the SMB segment, we have positioned our core offering targeting the “prosumer” market, or those individuals who both consume and produce a product. “TIM Black Empresas” has become the brand for the SMB portfolio, delivering unlimited voice calls and a variety of data packages, consistent with its strategy of providing “lots of minutes and lots of Internet, across all operators and anywhere in Brazil.” In addition to mobile connectivity, relevant Value-Added Services have been added to the main “TIM Black Empresas” offer in order to empower our business customers during their progress towards digital transformation, such as: cloud storage and backup, a website and online store builder, sales/field force automation and productivity apps. Those complimentary services were built based on revenue sharing agreements through strong partnerships with UOL, Fs, Datamob, Prouser and Deezer, that supports our aim to become our customers’ business partner rather than a pure connectivity provider.

We maintain a prominent position in the area of Internet of Things (known as IoT), especially in the AGRO segment, where since 2018 we have started an ambitious effort to fill the connectivity gap throughout rural Brazil in partnership with the agricultural sector. In 2020, in addition to consolidating its leadership in AGRO, we managed to evolve with projects in other verticals with action and cooperation with the ecosystem. Our strategy that has connectivity as the central point, our strongest attribute, but with complete solutions together with our partners in order to give more value to our customers and, at the same time, generate more revenue and loyalty.

Value-Added Services

We are constantly seeking to increase value to our customers through innovative offers and products, and 2021 was no exception. We offer, directly or through agreements entered into with third parties, Value-Added Services in varied categories, such as education, music, reading, games, videos and social networks.

Our most strategic Value-Added Services launched in 2021 was the partnership with Mulheres Positivas, a service relating to gender equality, in which the service offered hundreds of free professional and specialized courses and job opportunities for all of our client base.

We also continue the improvement of our portfolio through additional services provided by new strategic partners.

In 2022, we intend to continue to expand our partnerships with OTT’s and reinforce our strategy of giving our customers the best experience with Value-Added Services.

Financial and Other Services

In 2021, we continued to develop this business as well as the insurance services we relaunched in 2018 with a new portfolio of services, which allow us to take a broader approach to this market. For 2022, our primary focus is the launch of 5G and its associated services.

Digital Channels

In 2021, we continued to develop our digital channels as well as the insurance services we relaunched in 2018 with a new portfolio of services, which allow us to take a broader approach to this market. We launched new digital customer service channels, which aims to maximize convenience for our customers. We also started using a new tool called DialMyApp that shows a visual interactive voice response (known as IVR) on the customer's cell phone everytime the customer calls the contact center from an Android device. This is intended to enable our customers to resolve their issues directly on their smartphone without needing to go through the traditional phone service. We achieved first place in customer engagement on this platform among all Brazilian telcos. We also started customer service through RCS, a Google platform that allows easy interaction with our customers, with user-friendly visual elements, in addition to a more interesting cost composition. Once again, we were the first Telco to launch this service in Brazil.

Customer Service

In order to serve our customer base, almost 52 million customers, we aligned the insourced/outsourced ratio of our internally managed customer service operations to our outsourced customer service operation to the best practices of Brazilian telecommunications business. We operate through 20 customer care centers, two of our own and 18 outsourced, comprising around 12,997 customer service representatives (of which 3,542 are the purpose of offering dedicated to provide the best options in terms of offers and services to our multi-customer base). Our high value customer service and core or critical processes are maintained within our internal customer care centers.

As of December 31, 2021, we had more than 12.8 thousand points of sales through premium shops and dealers (exclusive or multi-brand) and consolidated partnerships with large retail chains. This figure includes 158 of our own stores. In addition to these retail stores, our customers have access to prepaid phone services through supermarkets, newsstands, and other small retailers, totaling more than 212 thousand points of sale throughout Brazil.

In December 2021, we launched our first concept store using a new format, which is intended to start the beginning of a new experience in our customer journey. The official opening of the concept store is scheduled for early 2022, and throughout the year, other concept stores following this new format are also planned. The new format will have several spaces where it will be possible to try smartphones and accessories already with 5G technology, as well as equipment for connecting homes using TIM Live fixed ultra-broadband. Consumers themselves will be able to carry out basic activities from consulting with our sales representatives, printing, paying invoices, purchasing plans and services, and even discussing with our tech experts tips for operating their devices, apps, and more.

For the corporate market, TIM has more than 397 third-party business partners and 101 employees focused on serving small- and medium-size companies and a direct sales force team of 86 employees focused on large companies.

Throughout 2020 and 2021, an important aspect of our customer service was digital customer service such as our mobile application Meu TIM and the Company’s website. The digital channels are also gaining relevance in customer self-caring, top up of prepaid customers and upselling of services. In addition to being a better customer experience due to the quick response it provides, digital channels also allow TIM to reduce costs such as customer service operations and sales commissions. During 2021, we continued to implement new features in our digital channels, increasing our ability to promptly resolve challenging issues that may arise for our customers.

In 2021, we worked to keep our “Customer Experience” foundational pillar as a focus (see “—Our Strategy”), creating initiatives that sought to put the customer as the center of decision-making. The approach used to promote this cultural transformation was guided by the relationship between customer and employee.

We have evaluated and taken action to improve the experience and professional development of our employees, with educational projects to promote engagement and insight, focused not only on technical, functional or soft skills competences, but also on the new capabilities required to reach industrial and business goals. These efforts strengthened the bonds between an employee’s business functions and the products and services they deliver to the customer. The impact was noticeable in our Organizational Climate Survey, a study performed by consulting company Mercer, considering several companies across the country, in which our employees’ performance in respect of “Quality and Customer Focus” attained by 1pp (86%), from 2020 to 2021. Compared to the other telecom companies that also use this survey, TIM is 10pp (84)% above average regarding this indicator. The business area responsible for supporting these initiatives was divided in three sections: Design, Execution and Monitoring.

The Design area created a policy with “Customer Experience” guidelines. This document defined expected behaviors and patterns in communication and interactions with customers, outlined a monitoring model, as well as refactored the products and services development cycles, to better cover all elements of Customer Experience.

The Execution area sought to solve legacy issues, with many of them concluded, which represented the efforts in the Customer Experience governance plan. These actions were grouped on four strategic pillars:

In addition, we continued to use the so-called “Net Promoter Score” as a fundamental key performance indicator to measure customer experience with our call center. There is an ongoing project to expand this survey to other of our customer service channels.

We have also sought to maximize customer satisfaction through improvements in our processes and systems, including customer journey mapping, where employees are invited to assume the customer perspective using empathy maps and design thinking tools. The goal of using these methods is to reduce customer effort, increase customer success and to ensure positive emotions towards TIM. We also work in teams to resolve critical issues and implement improvements in processes and systems.

We also enhanced our interactive voice response channels to include more customer oriented services.

We completed the migration of prepaid and postpaid consumer back office services (front end was implemented in 2015) to the Siebel customer relationship management, or CRM, platform. The migration to the Siebel system from legacy systems for corporate clients is still ongoing.

Lines of Revenue

Our revenues from mobile and fixed services includes: (i) monthly subscription charges, (ii) network usage charges for local mobile calls, (iii) roaming fees, (iv) interconnection charges, (v) national and international long distance calls, (vi) Value-Added Services, and (vii) co-billing. Additionally, we have revenues from sales of products (mobile handsets and accessories) and other customer platforms revenues.

Monthly Subscription Charges

We receive a monthly subscription fee under our postpaid mobile plans, which varies based on the usage limits under the relevant plan.

Usage charges are for minutes in excess of those included as part of the monthly subscription charge under the relevant postpaid plan.

Roaming Fees

We receive revenue pursuant to roaming agreements we have entered into with other mobile telecommunications service providers. When a call is made from within our coverage area by a client of another mobile service provider, that service provider is charged a roaming fee for the service used, be it voice, text messaging or data, at our applicable rates. Similarly, when one of our clients makes a mobile call when that customer is outside our coverage area using the network of another service provider, we must pay the charges associated with that call to the mobile service provider in whose coverage area the call originates at the applicable rate of such mobile service provider.

Automatic national roaming permits our customers to use their mobile telephones on the networks of other mobile service providers while traveling or “roaming” in the limited areas of Brazil not covered by our network, complementing our current mobile coverage. Similarly, we provide mobile telecommunications service to customers of other mobile service providers when those customers place or receive calls while in our network. Mobile service providers which are party to roaming agreements must provide service to roaming customers on the same basis that such providers provide service to their own clients. All such providers carry out a monthly reconciliation of roaming charges. Our roaming agreements have a one-year term and automatically renew for additional one-year terms, which are regulated and previously approved by Anatel.

Interconnection Charges

We receive interconnection revenues for any calls originating from another service provider’s network, mobile or fixed line, which is received by any mobile customer, of ours or of another provider’s, while using our network. We charge the service provider from whose network the call originates an interconnection fee for every minute our network is used in connection with the call. On the other hand, we must pay the fees for other telecommunications companies, when our users place a call to phones connected to other network operators.

We have entered into interconnection agreements with most the telecommunications service providers operating in Brazil, which include provisions specifying the number of interconnection points, the method by which signals must be received and transmitted, and the costs and fees for interconnection services. The interconnection among the networks of providers of telecommunications services of collective interest is mandatory and the interconnection agreements must be submitted to Anatel for approval. Nevertheless, even in the absence of ratification by Anatel, the parties to these interconnection agreements are obligated to offer interconnection services to each other.

The interconnection fees we were permitted to charge other mobile telecommunications providers, and which other mobile telecommunications providers charge us, have in the past been adjusted by inflation. Transition rules were defined and applied until July 2014, as set forth in Resolution No. 639/2014. Anatel effectively issued the rule for the definition of reference rates for entities with significant market power, based on a cost model, for VU-M, as well as maximum rates for the termination of calls on TU-RL. Since the issuance of Resolution No. 639/2014, interconnection fees have been decreasing based on a specific glide path, until 2019. Starting in 2020, Anatel has determined that VU-M values will rise slightly again. See “—Regulation of the Brazilian Telecommunications Industry—Interconnection Regulation.”

Long Distance

Telecommunications customers in Brazil are able to select long distance carriers on a per-call basis under the carrier code selection, or the CSP, introduced in July 2003, by punching in a two-digit code prior to dialing long distance. This regulation also increased the size of home registration areas, calls within which are local calls and, as a result, reduced the number of home registration areas.

For mobile customers, we offer long distance services throughout Brazil. This service allows our mobile customers the option of continuing to use our service for long distance calls, which we believe strengthens our respective relationship and loyalty, and enhances the perception of our brand as a comprehensive mobile telecommunications service. Mobile customers of other service providers can also choose to use our long distance service.

Under this structure, a customer is charged the VC1 rates directly by us only for calls made by and completed to a number registered within that customer’s home registration area. Long distance calls, however, are charged to a customer by the chosen long distance carrier. When our customer chooses other long distance carriers, in turn, the other carrier pays us a VU-M fee for any use of our network for a long distance call.

VU-M is the fee another telecommunications service provider pays to us for the use of our network by such provider’s customers, in this case for long distance calls. See “—Interconnection Charges.”

Co-Billing Services

Co-billing occurs when we bill our customers on behalf of another long distance service provider for services rendered to our customer by that carrier. Beginning July 2003, we started providing co-billing services to other telecommunication service providers operating in Brazil. The rates of such services are negotiated under the supervision of Anatel.

Sales of Product

We offer a diverse portfolio of handset models from several manufacturers for sale through our dealer network, which includes our own stores, exclusive franchises and authorized dealers. We are focused on offering an array of handsets, including essential and smartphones devices with enhanced functionality for Value-Added Services, while practicing a policy of increasing 4G smartphone penetration. Our mobile handsets can be used in conjunction with either our prepaid or postpaid service plans.

Billing and Collection

Our company-wide, integrated billing and collection systems are provided by a third-party vendors. These systems have four main functions: (i) customer registration, (ii) customer information management, (iii) accounts receivable management and (iv) billing and collection.

These billing systems give us significant flexibility in developing service plans and billing options.

Certain aspects of billing customers in Brazil are regulated by Anatel. For mobile and fixed telephones, currently if a customer’s payment is more than 15 days overdue, we can suspend the customer’s ability to make outgoing calls if preceded by a notification. If the payment is 45 days overdue, we can suspend the customer’s ability to receive incoming calls, also if preceded by a notification. For residential broadband, currently if a customer’s payment is more than 15 days overdue, we can reduce the speed of the customer’s broadband access and if the payment is 45 days overdue, we can suspend the customer’s broadband access. After 90 days from the customer’s payment due date, we generally discontinue service entirely, with a notification to the customer. Discontinuation of service is sometimes delayed, however, between 120 and 180 days after the due date for valued customers. The rules of suspension and discontinuation of fixed and residential broadband service are the same as those applied for the mobile service.

In March 2014, Anatel approved a single regulation for the telecommunications sector, with general rules for customer service, billing, and service offers, which are applicable to fixed, mobile, broadband and cable TV customers.

In order to avoid delinquency and discontinuation of service, however, we have invested in CRM models to identify customers with a higher propensity to early delinquency and also reinforced credit history checks for our customers prior to service activation. Although we continue to have one of the lowest delinquency rates in the segment, we noticed an increase in bad debt as a consequence of the expansion of the postpaid base of customers and the challenging economic environment.

During 2020, after the implementation of improved operational controls and collection strategies and even considering the pandemic environment, we accomplished a significant bad debt reduction.

In 2020, we expanded our capillarity of collection methods, being the only telecommunication company to offer the possibility of paying with the Instant Payment System from the Central Bank (PIX) to the entire customer base, which allows us the immediate recognition of payment and also the immediate release of the defaulting customer.

Pursuant to Anatel regulations, we and other telephone service providers periodically reconcile the interconnection and roaming charges owed among them and settle on a net basis. See “—Lines of Revenue—Interconnection Charges” and “—Lines of Revenue—Roaming Fees.” Seasonality

We have experienced a trend of generating a significantly higher number of new clients and product sales in the fourth quarter of each year as compared to the other three fiscal quarters. A number of factors contribute to this trend, including the increased use of retail distribution in which sales volume increases significantly during the year-end holiday shopping season, the timing of new product and service announcements and introductions, and aggressive marketing and promotions in the fourth quarter of each year.

Regional Overview

We provide 4G coverage in 4,715 cities to 98% of the urban population of Brazil, making our 4G network the most extensive in the country. We continued our infrastructure evolution and expanded our 4.5G coverage to 1,712 cities by the end of December 2021. Our 3G coverage reaches 4,022 municipalities and 94% of the urban population.

The following table shows information regarding Brazilian mobile telecommunications, at the dates indicated.

Our Network

Our wireless networks use 4G, 3G and 2G technologies and cover approximately 98% of the urban Brazilian population. In order to move toward 4G services, in October 2012, we acquired additional bandwidth in the 2,530-2,540 MHz and 2,650-2,660 MHz sub-bands, with national coverage, and the 450 MHz band in Espírito Santo, Paraná, Rio de Janeiro and Santa Catarina states.

Between 2007 and 2014, we acquired new RF authorizations used for 3G and 4G mobile telephone services at the 2100 MHz, 2500 MHz and 700 MHz bands. In September 2014, we invested approximately R$2.85 billion to acquire bandwidth in the 700 MHz range, which aligned with our strategy of expanding our broadband and 4G service across Brazil. We began providing our services in the 700MHz range in 2016. See “—Regulation of the Brazilian Telecommunications Industry—Frequencies and Spectrum Background”. In December 2015, Anatel auctioned left over radio frequencies in the 1,800 MHz, 1,900 MHz and 2,500 MHz bands. We submitted bids for the left over lots of the 2,500 MHz band, in the 2,500-2,510 MHz and 2,620-2,630 MHz sub-bands – known as P-Band, which had originally been auctioned in 2012. This particular P-Band spectrum provides for 4G mobile services. We acquired the lots for Recife, in the state of Pernambuco (Region AR 81), and Curitiba, in the state of Paraná (Region AR 41), based on our bids which totaled R$57.5 million. The corresponding authorization terms were signed in July 2016. During 2017, several municipalities throughout Brazil had their analog TV signals switched-off, freeing up the bandwidths in those regions for 4G mobile services. In 2018, the analog TV switch-off schedule was completed in regions where it is necessary to clean up the 700 MHz spectrum for the LTE. Therefore, by September 2019, all municipalities were able to receive TIM’s expanded 4G coverage through the 700 MHz band. Throughout 2020 and 2021, the entity created to ensure the spectrum cleanup, called the Entity for Administration of TV and RTV Channel Relocation and Digitalization Process, or EAD, is expected to fulfill the remaining auction obligations, concluding the relocations of broadcasters and the provision of interference solutions in order to complete the switch-off process and to make the spectrum fully available to mobile operators. In November 2021, we invested approximately R$1.1 billion to acquire the 2.3 GHz, 3.5 GHz and 26 GHz spectrum bands, aligned with our strategy of deploying 5G technology, with the expectation to launch 5G coverage in 2022. See “—Regulation of the Brazilian Telecommunications Industry—Frequencies and Spectrum Background” and “—Regulation of the Brazilian Telecommunications Industry—Authorizations and Concessions.” In connection with the conclusion of the Reorganization whereby TIM Celular was merged into the Company, see “—Item 4. Information on the Company—C. Organizational Structure,” the Company holds all of the authorizations previously issued in the name of other companies controlled, directly or indirectly, by TIM Participações

RF authorizations are generally valid for a period of 15 years and renewable for 15 more, and our current authorizations will start expiring in September 2022 (for details on spectrum licenses and expiration dates see “—Regulation of the Brazilian Telecommunications Industry—Frequencies and Spectrum Background”). In the case of authorizations that cannot be renewed, current telecommunications law sets forth that the spectrum is returned to the Federal Government under Anatel’s management. This is why reviewing the General Telecommunications Law has meaningful impact for the sector, as the proposed updated law allows for subsequent and unlimited renewals of radio frequency authorizations of up to 20 years each, generating an environment possibly more conducive to long-term investments.

We consider the purchase of any frequency made available by Anatel for the provision of mobile services as a priority, since having available frequency is core to our business. In 2021, we made R$3,052 in investments, primarily in capacity and coverage 4G, mainly using M-MIMO antennas, core functions virtualization, expansion and capacity enhancement of our optical transport networks, infrastructure resilience, quality maintenance and enabling of fiber-to-the-site and the mobile broadband MBB programs

These investments allowed us to reach, by the end of 2021, the milestone of 4,715 cities with 4G coverage, or 97.6% of the country’s urban population. We are thus the leader in 4G coverage in Brazil among mobile telecommunications providers, both by number of cities served and percentage of population covered.

On July 22, 2020, the Company obtained the approval of the Anatel and, on June 3, 2020, obtained the approval of the CADE for the execution of two onerous transfer contracts aimed at sharing 2G, 3G and 4G mobile network infrastructure, reinforcing the evolution process of the Brazilian telecommunications market in terms of network infrastructure sharing. For details see “—Site-sharing agreements.”

Our wireless network has both centralized and distributed functions, and includes mainly transmission equipment, consisting primarily of more than 58 thousand eNodeBs in our 4G network, more than 20 thousand NodeBs for the 3G layer and more than 15 thousand BTSs for 2G network as of December 2021, considering site-sharing, hardware equipment and software installation and upgrades. The network is connected primarily by IP radio links and/or optical fiber transmission systems distributed nationwide.

Another priority is developing our national network. In December 2021, we continued to increase the quantity of sites connected by optical fiber, reaching more than 8,000 of sites connected by optical fiber. The results are consistent with Anatel’s network quality requirements, and with TIM retaining its solid performance in 2021. Since national coverage and quality of service has improved substantially over the last few years, Anatel has shifted its focus in recent years. Anatel is now concentrating its efforts on smaller geographic areas, particularly in those areas where service is still considered poor.

The AES Atimus Acquisition and consequent creation of TIM Fiber (which was merged into TIM Celular in 2012, and TIM Celular was merged into the Company in 2018) has improved our optical fiber (or fiber optic) network presence in more than 31 cities including the metropolitan regions of Rio de Janeiro, São Paulo, Salvador, Goiânia, Recife, Manaus, Belo Horizonte and Distrito Federal. Our optical fiber network has capacity to offer high quality ultra-broadband service, available through our TIM Live service. and increase basic infrastructure to be applied in our fixed and mobile operations.

Our fixed broadband infrastructure is highlighted by the following characteristics:

Our switching exchanges and intelligent network platforms enable us to offer flexible, high quality voice service at extremely competitive prices. Our satellite network covers distant areas of the country and is being expanded and renewed to provide high private service.

As a general matter, telecommunications operators’ networks have tended to be designed, deployed and managed according to a vertical architecture model referred to as “end-to-end,” where the hardware and software are proprietary and dedicated to each network function. With the growing demand for differentiated services, the need for physical space, energy and speed have become critical and, consequently, companies’ capital expenditure and operating costs have tended to increase.

Such network architecture based on monolithic network elements requires a long time for development and deployment, impacting directly the time-to-market for launching new products or services and, consequently, reducing the generation of new revenues.

NFV is the new architectural paradigm that aims to address the infrastructural network transformation as a key step in the evolution of the implementation of new systems and network infrastructure, as it adopts the concept of consolidating standardized commercial off-the-shelf hardware elements that are available in virtual environments for shared use across various applications, accelerating the ability to deliver services, reducing costs and improving customer satisfaction. TIM aims to capitalize on the proposed benefits from such technology.

TIM understands that the NFV and the sharing of resources and equipment is the way to establish an economically more efficient structure, by reducing investment and/or operational costs while also reducing the time-to-market for launching new offers (an increasingly relevant factor in a competitive scenario).

By the end of 2021, we have deployed 14 new virtualized Core Network Datacenters (DCC) located in Rio de Janeiro (2), São Paulo (2), Fortaleza (2), Salvador, Brasília (2), Belo Horizonte (2), Belém and Curitiba (2), in addition to 19 new virtualized Edge Network Datacenters (DCE) located in Campinas, Porto Alegre, Natal, João Pessoa, Florianópolis, Blumenau, Maringá, Londrina, São Luis, Goiânia, Foz do Iguaçu, Santos, São José dos Campos, Uberlândia, Varginha, Feira de Santana, Teresina, Manaus and Ponta Grossa. Most of our core network functions are already running in a virtualized fashion by means of these network datacenters. The migration of additional network functions to a virtualized datacenter will be based on a roadmap of virtual network functions, or VNFs, respecting the maturity of each network function.

Similar to the movement of IT Systems to Public Cloud Infrastructure, Network Functions have also been planned to be migrated to the cloud, respecting their particularities regarding high availability and performance. In order to guarantee this movement, NFV Architecture had an important role for the evolution of these NFs from a Virtual environment (VNF) to a Cloud environment (CNF). As result of this journey, TIM intends to move Network workloads to a hybrid cloud (On-Premise and Public Cloud) throughout the next 3 years. TIM understands that Cloud Infrastructure is a second step (just after NFV) to establish an economically more efficient infrastructure, not only for reducing investment/costs, but also for speeding up project deployments and reducing time-to-market of new offers.

Based on the efficiency and on the robustness of the technologies used in the NFV and IP networks, in virtualizing its core network, TIM is also optimizing capital expenditures.

Therefore, our commitment to solid infrastructure and quality improvement allow the Company to develop projects such as: (i) unification of the functions of an Intelligent Network core signaling network and network data base through Unified Data Consolidation and (ii) the evolution of security platforms such as Session Border Controller that accomplishes IP interconnection in with other operators. We expect from these and other projects to be able to reduce our operating expenditures by decreasing leased lines and infrastructure sharing, simplifying maintenance processes and architecture/topology, increasing resilience even in conditions of disaster recovery and improving the customer experience by increasing the speed in which calls are set up and data is transmitted and improve the amount of time needed to make customers profiles available in our data base.

In 2011, TIM implemented a Policy and Charging Control (“PCC”), platform in accordance with the standards of the 3rd Generation Partnership Project, or 3GPP. This PCC made it possible for us to develop a brand new means to control fair use, as we are now able to reduce a given subscriber’s speed, block usage and offer additional data packets to maintain maximum speeds after the subscriber’s existing data packet is depleted. Since then, several innovative data offers have been launched that promote the usage of data, social media and streaming. This PCC platform is now evolving to an NFV model, which brings modernization and high scalability to support the increasing demand of mobile data and reduces the time-to-market when launching new data offers.

In 2014, TIM started to change our Mobile Packet Core platform to a Unified Packet Core based on the most advanced 3GPP Evolved Packet Core standards, providing a coordinated seamless mobility management in a HetNet access environment (full multiple-access nodes for 2G/3G/4G/Femto/WiFi) in order to support the huge increase in data demand in the Brazilian telecommunications market, as discussed elsewhere throughout this annual report on Form 20-F. The Evolved Packet Core platform is also evolving to an NFV model, based on 3GPP’s Control and User Plane Separation of EPC nodes. This enables flexible network deployment and operation, by distributed or centralized deployment and the independent scaling between control plane and user plane functions.

In 2017, TIM started to implement our Voice over LTE/4G, or VoLTE, platform following 3GPP standards, providing better voice quality and 4G service continuity, avoiding the need to resort to 2G/3G during voice calls. The VoLTE platform is also evolving to an NFV model, based on 3GPP’s nodes.

In 2018, TIM implemented a new security system to access its new and legacy platforms, called “Secure Password.” It uses a secure shell, or SSH, security protocol, monitors attempts of non-standard access and generates

related warnings (IAM-Identity Access Management). This process involves password encryption and a logical safe that only grants recovery to authorized users while also granting and recording accesses through video and text devices. More specifically, it features: (i) password authentication with a maximum validity of 90 days; (ii) authorization through a login administration interface; and (iii) audit (logs) generated by the system, allowing the traceability of user actions from the beginning to the end of each operation. The system also sends logs to a centralized system as a historical database. Additionally, TIM has a plan to mitigate network risk on a macro scale that prioritizes the critical network infrastructure based on a risk map, or the Network Resilience Plan. The Network Resilience Plan allows the Company to focus on the main issues, and these in turn become the basis for crafting short-, medium- and long-term mitigation measures in order to enhance the robustness of the network.

Sources and Availability of Raw Materials

Our business and results of operations are not significantly affected by the availability and prices of raw materials.

Site-Sharing and Other Agreements

Site-Sharing Agreements

With the objective of avoiding unnecessary duplication of networks and infrastructure, Anatel allows telecommunications service providers to use other providers’ networks (long distance, backhaul and spectrum frequencies, among others) as secondary support in providing telecommunications services, with a focus on reducing costs and increasing the penetration of mobile services in Brazil. Therefore, we have allowed other telecommunications service providers in our region to use our infrastructure, and we have used other providers’ infrastructure, pursuant to site-sharing agreements with such operators.

Based on such Anatel policy, in November 2012, TIM Celular (which has been merged into the Company in connection with the Reorganization) formalized with Oi an agreement for the reciprocal assignment of their LTE networks (4G technology) in certain cities, which was approved by Anatel and CADE, which is the Brazilian antitrust agency and has the mission to ensure free competition in the market, not only by investigating and ultimately deciding on the competitive matter, but also by disseminating a free competition culture.

In April 2014, TIM Celular (now TIM S.A.) and Oi entered into a new agreement to negotiate the joint construction, implementation and reciprocal assignment of parts of their respective GSM (2G) and UMTS (3G) network infrastructures in cities with less than 30,000 inhabitants, which was also approved by Anatel and CADE.

In July 2015, TIM Celular (now TIM S.A.), Oi and Vivo entered into an agreement for the reciprocal assignment of LTE network media (4G), similar to the agreement between TIM Celular (now TIM S.A.) and Oi in 2012, but also covering frequencies sharing. As with the prior sharing agreements, Anatel and CADE approved the agreement between the parties.

Also in 2015, TIM Celular (now TIM S.A.), Vivo, Claro and Oi filed with CADE a Term of Commitment with the objective of negotiating the joint contracting of one or more companies to carry out the construction, installation and provision of infrastructure in indoor environments (such as shopping malls) in several locations in Brazil, which was approved without restriction by CADE.

In November 2015, the Company, thorough TIM Celular and Intelig, both merged into the Company, and Vivo filed an agreement to share UMTS network (3G) under a multiple operation core network, RAN sharing model which includes frequency sharing in certain cities based on their rural coverage obligations, which was also approved without restrictions.

In March 2018, due to the mediation process between TIM and Oi, a new RAN sharing agreement was executed, which changed the sharing modality described in the 2012 agreement (technological evolution from the multi-operator radio access network to the multi-operator care network) and included part of the 1,800 MHz radio frequency bands. CADE and Anatel approved the operation without any restrictions.

On July 23, 2019, the Company and Telefônica Brasil entered into a memorandum of understanding, or the Vivo MoU, to start negotiations regarding: (i) sharing of single-grid 2G network; (ii) establishment of new infrastructure sharing agreements for the 4G network in 700Mhz, directed to cities with fewer than 30,000 inhabitants, which in the future may be expanded to larger cities; (iii) other network sharing opportunities in other frequencies and technologies; and (iv) other opportunities in efficiency and cost reduction in operations and network maintenance. We and Telefônica Brasil believe that the potential developments from the concepts set forth in the Vivo MoU would result in improved services at both carriers, as well as synergies and efficiencies in the allocation of investments and operating costs.

On December 19, 2019, pursuant to the Vivo MoU with Telefônica Brasil, two new sharing agreements have been entered into regarding: (i) the creation of a unique network in 2G technology; and (ii) a single-grid agreement that will result in an expansion of 3G and 4G networks and a network consolidation in small cities (with less than 30,000 inhabitants). Both agreements were approved without restrictions by CADE and Anatel in 2020, reinforcing the evolution of the Brazilian telecommunications market in terms of network infrastructure sharing.

Our Operational Contractual Obligations

For more information on our material contractual obligations, see “Item 10. Additional Information—C. Material Contracts.”

Interconnection and Other Agreements

We have entered into interconnection agreements with most of the telecommunications service providers operating in Brazil. The terms of our interconnection agreements include provisions specifying the number of interconnection points, the method by which signals must be received and transmitted, and the costs and fees for interconnection services. Interconnection agreements must be submitted for Anatel’s approval. Nevertheless, even in the absence of ratification by Anatel, the parties to these interconnection agreements are obligated to offer interconnection services to each other. See “—Interconnection Regulation.”

Roaming Agreements

We have entered into roaming agreements for automatic roaming services with other mobile operators outside our regions. Automatic roaming allows our customers to use their mobile telephones on the networks of other mobile operators while traveling abroad or out of TIM coverage areas in Brazil. Similarly, we provide mobile services for customers of other mobile operators when those customers place or receive calls while visiting Brazilian cities with TIM coverage. We provide services for the clients visiting our network on the same infra-structure basis provided to our own clients. All of the mobile operators party to these agreements must carry out a monthly reconciliation of roaming charges with its roaming partners.

National Roaming Agreements

In 2017, Anatel required TIM, Claro, Oi and Vivo to guarantee the provision of mobile services (voice, SMS and data) in all cities with less than 30,000 inhabitants through roaming agreements. Over time, we have been building our own network in cities where we depended on roaming coverage from other operators. Currently, only 1,090 cities do not have their own network and depend on roaming services, with the goal of ending this dependence by early 2023.

International Roaming Agreements

We have international roaming agreements available in 210 different countries with 4,249 international operators that encompass 585 individual (PMNs) networks. These agreements include at a minimum voice service, and may be enhanced based on the technology available on the visiting network and can include voice, SMS and data (2G, 3G and 4G). Our international roaming agreements have steadily expanded in recent years. By the end of 2021, we expanded our 4G data coverage to 25 new networks, meaning now we offer 4G roaming in 95 countries, covering the main travel destinations for Brazilians.

In November 2018, Brazil entered into a free trade agreement with Chile, which resulted in the end of international roaming charges between the two countries. In October 13, 2021 the Legislative Decree No. 03/2021, which approved the free trade with Chile, was sanctioned by the President of the Senate. With the approval, the agreement came into force on January 25, 2022 and the end of roaming charges is expected by January 25, 2023. The agreement signed in July 2019 with other Mercosur countries to eliminate international roaming charges are still pending Brazilian Congress approval and will only be valid after two or more countries have ratified the agreement before the secretariat of Mercosur.

Fraud Detection and Prevention

“Subscription fraud,” which consists of using identification documents or data personal information of another individual to obtain mobile services, is the main fraud relating to mobile, fixed and long distance service. We are focused on implementing prevention measures in our points of sales to avoid such subscription fraud. Examples of prevention measures include digital authentication for our sales front-end system, a strong training program, maintaining a blacklist of offenders to prevent fraud, analysis of the documentation presented and monitoring and identification of point of sale. We also work to detect and prevent fraud by frequently improving and updating our traffic behavior monitoring and subscriber data.

Our security operations management develops programs and strategies to mitigate fraud risks through macro business processes such as:

Network: Actions aimed to combat theft, robbery or damage of equipment and network infrastructure by the application of physical and electronic protections, such as equipment tracking, installation of protective security equipment, virtual and physical surveillance and intelligence analysis.

Investigations of Specific Incidents: These anti-fraud efforts are focused on the reduction of illicit activities. The program consolidates and analyzes all the facts related to known incidents in order to identify circumstances in which the Company’s services may be being used to perpetuate noncompliance with laws, codes and other policies such as extortion, pedophilia, aggression, theft, drug trafficking and harassment.

Personal Security: These efforts focus on the combined use of organizational, technical and human resources aimed at preserving the physical, intellectual and emotional integrity of the human resources of the group, ensuring compliance with the precepts pointed out in the security operations mission and focused on the foreign public on a visit to Brazil.

Commercial Security: These efforts seek to mitigate the losses resulting from theft and robbery of smartphones, among them the deployment of safes in the stores for the storage of high value devices in all stores, prioritizing street-front stores.

Security in Logistics: These efforts are directed to combat loss due to theft or theft of merchandise whether in transportation or storage.

Security Compliance: Active monitoring of the emergence of new legislation related to customer data security and related internal compliance efforts.

Taxes on Telecommunications Goods and Services

The telecommunications goods and services offered are subject to a variety of federal, state and local taxes (in addition to taxes on income), the most significant of which are ICMS, ISS, COFINS, PIS, FUST, FUNTTEL, FISTEL, CONDECINE and Corporate Income Tax and Social Contribution on Net Income, which are described below.

rates between 25% and 35%. The ICMS tax rate levied on the sale of mobile handsets and other products such as modem and SIM cards averages between 17% and 20%. With respect to the sale of mobile handsets, among other goods, ICMS may be charged in a different tax regime, under which another taxpayer in the distribution chain of the goods (such as, for example, the manufacturer of the goods) is required to anticipate and pay ICMS amounts that would otherwise be due in other steps of the distribution chain. There is also an exception for certain handsets whose manufacturers are granted certain local tax benefits, thereby reducing the rate to as low as 7%.

In 2005, Anatel enacted Ordinance No. 7/05 requiring that FUST should be paid on revenues arising from interconnection charges since its effectiveness. A notice was issued deciding that we must adjust values on the FUST calculation basis in order to include interconnection revenues received from other telecommunications companies. A writ of mandamus was filed against Anatel to avoid the terms of Ordinance No. 7/05. The first level decision was issued in our favor. Such decision was challenged by Anatel and the Appeal judgement confirmed the first level decision. Anatel appealed to High Courts in order to reverse the Appeal decision.

In December 2020, Law No. 14,109 (later modified by Law No. 14,173/2021) was approved with the purpose of stimulating the use of FUST to expand and improve the quality of telecommunications services, reducing regional inequalities and stimulating the use of new technologies to promote economic and social development. In the case of using FUST’s resources, the law requires the connection of all public schools by 2024 with broadband internet access. The law also provided a 50% reduction in the payment of the

mandatory annual contribution of telecommunications operators to the Fund when they execute programs, projects, plans, activities, initiatives, and actions approved by the Fund's Management Council through the use of their own resources. This requirement remains in force until December 2016, but it may be further renewed.

In the first quarter of 2022, the Federal Government signed Decree 11,004/2022, which regulates the use of FUST and establishes directions for the use of resources by the Management Board, which should be instituted in the first half of 2022.

Effective in 2001, the installation and inspection fee is assessed based on net activations of mobile numbers (that is, the number of new mobile activations reduced by the number of cancelled subscriptions), as well as based on the net additions of radio base stations. The operations inspection fee equals 33% of the total amount of installation inspection fees that would have been paid with respect to existing equipment. The public funds raised from this installation fee are appropriated to either the Brazilian Communication Company (“EBC”), or the Brazilian National Cinema Agency (Agência Nacional do Cinema) (“ANCINE”), in order to benefit Brazilian cinema industry. Also, Anatel charges the installation inspection fee when there is an extension of the term of validity of the right to use radio frequencies associated with the operation of the personal mobile service. The Company understands that such collection is unjustified and is challenging this rate in court.

In December 2020, Law No. 14,108 was sanctioned and exempts FISTEL for 5 (five) years from the base stations and equipment that integrate the machine to machine (M2M) ecosystems and, also, extinguishes the prior licensing. The definition and regulation of M2M communication systems shall be established by Anatel. The Brazilian government also laid out in the budget law for 2021 a tax exemption forecast of FISTEL value. Additionally, in June 2021, Law No. 14,173 was approved, lowering the FISTEL fees on VSATs from R$201.12 to R$26.83.

The rules for deductibility of goodwill were maintained for transactions which occurred prior to the end of 2017. The tax treatment by TIM Celular (now TIM S.A.) of the goodwill arising from the purchase of the companies AES Atimus SP and RJ was not impacted by the new rules.

Regarding dividends, Law No. 12,973 ensured the full and unconditional exemption on payment or credit of profits or dividends earned between 2008 and 2013, previously paid or not. Uncertainty remained, however, in relation to exemption on profits and dividends generated in the calendar year 2014, if higher than the taxable income in the same period in the case of companies that do not opt for early adoption of the new post-RTT tax regime that year. According to the Federal tax authorities the exception is not applicable to the excess amount, or in other words, to the profits and dividends paid in excess of the taxable income.

Dividends are not subject to withholding income tax when paid. However, as the payment of dividends is not tax deductible for the company that is distributing them, there is an alternative regime for stockholder compensation called “interest on equity,” which allows companies to deduct any interest paid to stockholders from net profits for tax purposes.

These distributions may be paid in cash. The interest is calculated in accordance with daily pro rata variation of the Brazilian government’s long-term interest rate (“TJLP”), as determined by the Central Bank from time to time, and cannot exceed the greater of: (1) 50% of the net income (before taxes and already considering the deduction of the own interest amount attributable to stockholders) related to the period in respect of which the payment is made; or (2) 50% of the sum retained profits and profits reserves as of the date of the beginning of the period in respect of which the payment is made.

Any payment of interest to stockholders is subject to withholding income tax at the rate of 15% (or 12.5% for some jurisdictions, as provided in certain Double Taxation Treaties), or 25% in the case of a stockholder domiciled in a Low or Nil Tax Jurisdiction. These payments may be qualified, at their net value, as part of any mandatory dividend. As described herein, we and our subsidiaries paid interest on equity in 2021. Please refer to ““Item 5. — Operating and Financial Review and Prospects” —Dividend  Distribution —Interest on Equity” for detailed information.

Tax losses carried forward are available for offset during any year up to 30.0% of annual taxable income. No time limit is currently imposed on the application of net operating losses on a given tax year to offset future taxable income within the same tax year, nevertheless there is no monetary restatement.

Companies are taxed based on their worldwide income rather than on income produced solely in Brazil. As a result, profits, capital gains and other income obtained abroad by Brazilian entities are added to their net profits for tax purposes. Therefore, profits, capital gains and other income obtained by foreign branches or income obtained from subsidiaries or foreign corporations controlled by a Brazilian entity are computed in the calculation of an entity’s profits, in proportion to its participation in such foreign companies’ capital.

In the end of 2017, the Brazilian Federal Revenue Office (“RFB”), issued Normative Instruction No. 1,771/2017 in order to determine the tax treatment due to the accounting CPC 47 – Customer Contract Revenue, which tax treatment went into effect in 2018.

Income tax and social contribution were regulated by Decree 580/2018 and Normative Instruction RFB No. 1,700/2017 in addition to other federal laws and decrees. In December 2018, this decree was revoked and replaced by Decree No. 9,580, which consolidates the main provisions related to income tax and social contribution. As of the date hereof, no relevant impacts to the Company were identified with regard to such changes.

Regulation of the Brazilian Telecommunications Industry

General

The telecommunications sector is regulated by Anatel, which was established by law and is administratively independent and financially autonomous from the Ministry of Communication (Ministério das Comunicações). Anatel is responsible for reviewing and amending all administrative regulation regarding services, completion and customer’s rights related to telecommunications, issuing formal authorizations and performing inspections, as set forth in the General Telecommunications Law and the Regulamento da Agência Nacional de Telecomunicações, or the Anatel Decree.

Despite liberalization, which occurred in 1997, the Brazilian telecommunications market still faces persistent dominant positions held by fixed incumbent operators. In particular, broadband access is currently offered by operators over their own infrastructure and the respective regulatory framework is not always based on effective implementation of the wholesale access obligations.

In 1998, a presidential decree approved the first General Plan for Universalization Goals (Plano Geral de Metas de Universalização) (“PGMU I”), obligations binding on the landline telephony services (Serviço Telefônico Móvel Comutado) (“STFC”), applicable only for fixed incumbents. PGMU is reviewed every 5 years, and the last universalization plan, formulated by the government, was published in January, 2021 considering that fixed telephony concession will end in 2025. The PGMU V, replaces the 4G targets established in PGMU IV for construction of a backhaul in the municipalities that do not have a fiber optic connection. A presidential decree issued on June 30, 2011, established a bidding process for 4G RFs, an important landmark for the telecommunications sector. The bid occurred in 2012 and, in order to guarantee full rural service by 2018, Anatel linked the 4G blocks in the 2,500 MHz band to the 450MHz band in specific geographic regions of Brazil. As a result, the four winning operators of the 4G blocks in the 2,500 MHz band linked to the 450MHz band are subject to coverage commitments in rural areas. Such presidential decree also resulted in two new regulations to measure mobile and fixed broadband quality standards.

Another important set of rules is the Decree No. 9,612/2018, or the Connectivity Plan, which established a series of guidelines for execution of terms of conduct adjustment, onerous granting of spectrum authorization and regulatory acts in general which includes: (i) expansion of high capacity telecommunications transport networks; (ii) increased coverage of mobile broadband access networks; and (iii) broadening the coverage of fixed broadband access network in areas with no available internet access by means of this type of infrastructure. It also establishes that the network implemented from the commitments will be subject to sharing from its entry into operation, except when there is appropriate competition in the respective relevant market. As well as Decree No. 10,480/2020 that regulates the Antennas Law (Law No. 13,116/2015) with the objective of stimulating the development of the telecommunications network infrastructure.

Federal Government

In 2021 there were some important ordinances published, namely: (i) Ministry of Communications Decree No. 2,447/2021, which approved TIM’s issuance of up to R$5,753 billion in debentures. (ii) Ministry of Communications Decree No. 2,556, which set priorities and goals for the establishment of investments determined by Anatel. (iii) Decree No. 10,748, which established the Federal Network for the Management of Cyber Incidents, regulating the National Information Security Policy, which aims to improve and coordinate the bodies and entities of the federal public administration in the prevention, treatment and response to cyber incidents. (iv) Decree No. 10,887, which provided for the organization of the National Consumer Defense System, with the objective of guaranteeing greater protection to consumer relations, increasing legal certainty, and making the administrative process more efficient. (v) Data Protection Authority Decree No. 15, which established the Governance Committee, responsible for establishing institutional strategies and strategic guidelines related to public governance.

Also, there were some relevant decrees involving 5G. They were: (i) Decree No. 10,799 which updated Decree No. 9,612/2018 (telecom public policies), allowing the Government’s network to be built by other entities, not only Telebras. (ii) Decree No. 10,800 established the Amazon Integrated and Sustainable Program (PAIS). One of its objectives is to expand telecom networks to the Amazon region, in addition to creating a management committee to monitor them, among other provisions. (iii) Ministry of Communications Decree No. 1,924/21 about 5G guidelines, mainly about network security; obligation to provide an exclusive government network; backhaul for agribusiness; coverage of federal highways aligned with the Ministry of Infrastructure, among others.

Anatel

Over the years, Anatel has published several Resolutions that apply obligations to the telecommunications sector, among which we can highlight:

Resolutions published in 2021

Main Public Consultations held in 2021

Telecommunications Self-regulation System

In March 2020, telecommunication operators signed the Telecommunications Self-Regulation System, or SART, which proposes to establish common rules and procedures that must be followed by all participating companies, in relation to the most material topics in the relationship between providers and customers, such as telemarketing (approved in September 2019), offers (approved in March, 2020), billing (approved in February, 2021) and attendance (approved in March, 2020).

Review of the Current Regulatory Model for the Provision of Telecommunications Services

In 2019, PLC 79/2016 was approved and converted into Law No. 13,879. The Law entered into force on October 4, establishing a new regulatory framework for the telecommunications sector in Brazil, the major regulatory change in 20 years

The new telecommunications framework allows the fixed telephone concessionaires to adapt their agreements from a concession regime to an authorization regime. This change of concession to authorization must be requested

by the concessionaire and it should be approved by the Anatel. In return, concessionaires must, among other conditions, make investment commitments to expand fixed broadband services, in areas without adequate competition for these services in order to minimize gaps and inequalities between Brazilian areas. Additionally, it also changes the rules on authorization of radiofrequency uses, establishing subsequent renewals and allows Radiofrequency trading among players (spectrum secondary market).

In June 2020, the Federal Government published Decree No. 10,402/2020 which regulates Law No 13,879/2019 and provides for the adaptation of the concession instrument to authorization of telecommunications service and on the extension and transfer of radiofrequency authorization, grants of telecommunications service and satellite exploration rights.

Decree No. 10,402/2020 establishes that the partial or full transfer of the authorization to use radio frequencies between telecommunications service providers will be carried out against payment by Anatel and must be preceded by Anatel’s consent, in addition to enabling the maintenance of obligations associated to radiofrequencies (serving the public interest), the application of restrictions of a competitive nature when necessary/convenient and the analysis of tax regularity of the company to which the authorization is being transferred. It also confirmed that the current authorizations are covered by the new rule for successive renewals.

Authorizations and Concessions

With the privatization of the Telebrás system and pursuant to the Minimum Law (Lei Mínima), Band A and Band B service providers were granted concessions under Cellular Mobile Service (Serviço Móvel Celular), or SMC, regulations. Each concession was a specific grant of authority to supply mobile telecommunications services in a defined geographical area, subject to certain requirements contained in the applicable list of obligations attached to each concession.

Our predecessors were granted SMC concessions and in December 2002, such SMC concessions were converted into PCS authorizations, with an option to renew the authorizations for an additional 15 years. We acquired PCS authorizations in conjunction with auctions of bandwidth by Anatel in 2001, and subsequently acquired additional authorizations and operations under the PCS regulations as well.

In connection with the conclusion of the Reorganization whereby TIM Celular was merged into the Company (see “Item 4. Information on the Company—C. Organizational Structure”). The Company holds all of the authorizations previously issued in the name of other companies controlled, directly or indirectly, by TIM Participações.

Obligations of Telecommunications Companies

In 2011, Anatel published Resolution No. 575/11 regarding the review of the regulation on the management of quality of service – PCS. The new regulation established new quality goals, evaluation criteria, data collection and quality monitoring of service providers – PCS. The Anatel regulation aims to create a comprehensive model of quality management of the PCS providers providing preventive and proactive on the part of Anatel, through the incorporation of indicators and benchmarks that allow the systematic evaluation of the quality of service in all its dimensions. Anatel also published Resolution No. 574/11 in 2011, which set broadband quality measurement standards.

In March 2014, by means of Resolution No. 632/2014, Anatel approved the adoption of a single regulation for the telecommunications sector, the RGC, with general rules for customer service, billing, and service offers, which are applicable to fixed, mobile, broadband and cable TV customers. In 2018, Anatel held a subsidies grant, which is an opinion-gathering tool similar to, but at the preparation stage of a public consultation, aiming to improve the RGC in respect of the digitalization of processing and customer services, as well as billing and contracting services. A public consultation is expected in 2020. . In December 2020, Anatel enacted Public Consultation 77 in order to review Resolution 632/2014. The new RGC is expected to be approval in the first half of 2022.

In December 2019, Anatel approved RQUAL, which is expected to enter into force in 2022. See “—Quality Management Regulation.”

PCS Regulation

In September 2000, Anatel promulgated regulations regarding PCS wireless telecommunications services that are significantly different from the ones applicable to mobile companies operating under Band A and Band B.

According to rules issued by Anatel, renewal of a concession to provide mobile telecommunications services, as well as permission from Anatel to transfer control of cellular companies, are conditioned on agreement by such cellular service provider to operate under the PCS rules. TIM Sul, TIM Nordeste and TIM Maxitel converted their cellular concessions into PCS authorizations in December 2002, and later transferred them to TIM Sul, TIM Nordeste and TIM Maxitel, which are now TIM S.A. (following the Reorganization and various intercompany mergers discussed herein) subject to obligations under the PCS regulations. See “—Authorizations and Concessions.”

In recent years, Anatel initiated certain administrative proceedings against TIM Celular (now TIM S.A.) for noncompliance with certain quality standards and noncompliance with its rules and authorization terms. We have been fined by Anatel in some proceedings and are still discussing the penalty imposed in appeals before the agency. As a result of these proceedings, Anatel applied some fines that did not cause a material adverse effect on our business. In 2019, the total amount of these fines was R$708.1 million. However, only R$32.3 million was classified as “probable loss” by our legal advisors. The significant amount related to fines classified as “possible loss” is a result of ongoing litigation.

On August 22, 2019, Anatel’s board of officers unanimously approved the execution of a TAC with TIM S.A. The agreement covers fines imposed against us in the total amount of R$639 million. The commitment we assumed, as also approved by our board of directors on June 19, 2020, foresees actions to develop our services from three different perspectives: (i) customer experience, quality and infrastructure, through initiatives to improve the licensing process of base stations, efficient use of resources, (ii) evolution of digital service channels, decreasing complaint rates and user repair demands, and (iii) reinforcement of transportation and access networks. In addition, the agreement also includes the commitment to bring mobile broadband through the 4G network to 350 cities with less than 30 thousand inhabitants thus reaching over 3.4 million people and the application of Internal Controls Management to ensure compliance with the closed proposal and the commitment to not impose inspection obstructions. As released to the market in June 16, 2020, and previously approved by Anatel on August 22, 2019, the TAC provided the implementation of the new infrastructure in three years, with our assurance that these areas will be shared with other providers

We continue to do our best to fully comply with our obligations under the PCS regime or with future changes in the regulations to which we are subject. See “—Obligations of Telecommunications Companies,” “Item 3. Key Information—D. Risk Factors—Risks Relating to our Business” and “Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Legal Proceedings.”

Significant Market Power

In November 2012, Anatel published a new competition framework known as the PGMC 2012. Also in November 2012, Anatel published a series of regulations identifying groups with significant market power in the following relevant markets as defined by the PGMC 2012: (i) wholesale offer of fixed access infrastructure for data transmission through copper or coaxial cable in rates equal or higher than 10 Mbps (Act No. 6,617, of November 8, 2012); (ii) wholesale offer of fixed infrastructure for local and long distance transportation for data transmission in rates equal or higher than 34 Mbps (Act No. 6,619, of November 8, 2012); (iii) passive infrastructure for transport and access networks (Act No. 6,620, of November 8, 2012); (iv) mobile network termination (Act No. 6,621, of November 8, 2012); and (v) national roaming (Act No. 6,622, of November 8, 2012).On December 5, 2016, Anatel published public consultations on (i) the revision of PGMC 2012’s relevant markets and remedies, and (ii) the proposal of a specific Regulation for the Approval of Reference Offers, for public comment until March 22, 2017.

In July 2018, Anatel published the New PGMC, which revised PGMC 2012 and created new markets: (i) mobile network; and (ii) national roaming; and (iii) high capacity data transport. According to the New PGMC proposal, cities in Brazil will be classified by levels of competition (1 – competitive, 2 – moderately competitive, 3 – less competitive, 4 – non-competitive), and asymmetric measures will be applied according to the market

competition. In addition, also based on the proposal submitted to public consultation, wholesale relevant markets will be defined as follows:

Under the New PGMC, TIM has been classified as having significant market power in the following markets: (i) mobile network termination (otherwise referred to as the mobile network termination market); (ii) national roaming; and (iii) high capacity data transport (five municipalities). The measures applied to an significant market power operator in those markets include: (i) the application of mobile termination rates on a glide path based on a price cap system and the partial application of the Bill & Keep system (at a 50% threshold (i.e., not a significant market power operator pays only if the terminated traffic on the significant market power operator network is more than 50% of the total traffic exchanged) and only until the next revision of the New PGMC in 2021) and (ii) an obligation to offer the service of national roaming service to operators not having significant market power.

Due to such classification, we are subject to increased regulation under the New PGMC, which could have an adverse effect on our business, financial condition and results of operations. Specifically, because we have been classified as having significant market power in the mobile network termination market, the rates charged by mobile service providers to other mobile service providers to terminate calls on their mobile networks, or VU-M, are regulated. On July 4, 2014, Anatel approved, by means of Resolution No. 639/2014, a rule for the definition of maximum reference rates for entities with significant market power, based on a cost model, for VU-M, TU-RL, and EILD. Pursuant to Anatel’s rule, reference rates will decline based on a glide path until the cost modeling known as BU-LRIC is applied (in 2019, for VU-M and TU-RL; and in 2020, for EILD). On July 7, 2014, Anatel published the corresponding Acts Nos. 6,210/2014, 6,211/2014 and 6,212/2014, which determined the specific reference rates effective as of February 2016. On December 19, 2018, Anatel published the corresponding Acts Nos. 9,918/2018, 9,919/2018 and 9,920/2018, which determined the specific reference rates effective as of February 2020. Before coming into force, Anatel started revising these acts and, on February 24, 2020, published the new Acts Nos. 986/2020 and 987/2020.

Because of our classification as having significant market power in the national roaming market, we must also offer roaming services to other mobile providers without significant market power at the rates approved by Anatel. We are also required to provide access to our high capacity data transport network due to our classification as having significant market power in that market.

For additional detail, see “—Lines of Revenue—Network Usage Charges,” “—Lines of Revenue—Roaming Fees,” “—Lines of Revenue —Interconnection Charges” and “—Lines of Revenue—Long Distance” above.

Interconnection Regulation

Telecommunication operators must publish a public interconnection offer on both economic and technical conditions and are subject to the “General Interconnection Regulatory Framework” issued by Anatel in 2005.

In October 2011, Anatel established a mechanism for reducing fixed-to-mobile call rates, that results on a glide path to the reduction of mobile interconnection rates (VU-M) from 2012 to 2018, in accordance with Resolution No. 600/2012.

In addition to the VU-M reduction, Anatel established a bill and keep, or B&K, rule between significant market power and non-significant market power PCSs. From January 2013 until February 2015, the B&K was 80%/20%. On February 12, 2015, Anatel approved, by means of Resolution No. 649/2015, the following new B&K percentages, amending the percentages established by Resolution 600: 75%/25%, from 2015 until 2016; 65%/35%, from 2016 until 2017; 55%/45%, from 2017 until 2018; and 50%/50%, from 2018 until 2019, which was the object of a judicial suit (ongoing), in order to suspend its effects. In July 2015, we filed a lawsuit seeking to annul Resolution No. 649/2015 and maintain the percentages originally established by Resolution No. 600/2012, which currently remains pending a final decision. However, as discussed above, the New PGMC in 2021 set the partial Bill & Keep threshold to 50% (i.e., a non-significant market power operator pays only if the terminated traffic on the significant market power operator network is more than 50% of the total traffic exchanged) and will be applied until the next revision of the New PGMC scheduled for 2022. In addition, Anatel determined the end of the existing additional 20% on the value of mobile termination rate paid by significant market power operators to non-significant market power operators.

Related to fixed interconnection, Anatel revised the criteria for pricing the use of fixed networks in May 2012. According to such regulation, after January 1, 2014, a full B&K regime (in which no payments are due for the traffic termination) was implemented for local STFC operators dealing with other local STFC operators. Currently, therefore, no payments are due for the use of a local STFC operator’s network by other local STFC operator. With respect to interconnection of STFC operators with long distance and mobile operators, we understand that, in 2012, when Anatel issued PGMC 2012, the asymmetrical measure that permitted STFC operators without significant market power to charge a TU-RL 20% higher than the TU-RL charged by STFC operator, with significant market power was revoked. In September 2016, we filed a lawsuit on this subject, which is still pending a final decision.

On July 4, 2014, Anatel approved, by means of Resolution No. 639/2014, a rule for the definition of maximum reference rates for entities with significant market power, based on a cost model, for VU-M and TU-RL, and for EILD. On July 7, 2014, Anatel published the corresponding Acts No. 6,210/2014, 6,211/2014 and 6,212/2014, which determined the specific reference rates effective as of February 2016.

On February 24, 2017, considering the glide path provided in Act No. 6,211, VU-M rates were again reduced, depending on the region, to the level of approximately R$0.05, in 2018, it was also reduced to levels of R$0.03, in 2019, it was reduced to levels of R$0.01 and, in 2020, it was reduced to levels of R$0.03. In December 2020, Anatel published Acts setting forth mobile termination rate which will be valid from 2020 until 2023.

Wholesale Rates Regulation

Under our PCS authorizations, we are allowed to set prices for our service plans, subject to approval by Anatel, provided that such amounts do not exceed a specified inflation adjusted cap. Anatel currently uses the telecommunication services index (Índice de Serviços de Telecomunicações), or IST, a specific price inflation index that it developed, in evaluating prices and determining the relevant cap for prices charged in the telecommunications industry. As mentioned above, on July 4, 2014, Anatel approved the calculation of VU-M, TU-RL and EILD reference rates based on a cost model. We expect that the adjustment of our prices will follow the market trend, and that the adjustment will be below the annual inflation rate based on the IST.

Number Portability

In March 2007, Anatel issued a new regulation regarding number portability in Brazil for fixed telephony and PCS providers. Portability is limited to migration between providers of the same telecommunications services. For PCS providers, portability can take place when a customer changes its services provider within the same Registration Area as well as when a customer changes the service plan of the same area. Anatel finished the nationwide NP implementation schedule in March 2009.

Value-Added Services and Internet Regulation

Value-Added Services are not considered under Brazilian telecommunications regulations to be telecommunications services, but rather an activity that adds features to a telecommunications service. Regulations require all telecommunications service providers to grant network access to any party interested in providing Value-

Added Services, on a non-discriminatory basis, unless technically impossible. Telecommunications service providers also are allowed to render Value-Added Services through their own networks. Internet connection, when offered to users on a single basis, by parties other than telecommunications service providers, is considered by Brazilian legislation to be a value-added service, and its providers are not considered to be telecommunications companies. Current regulations allow us or any other interested party to offer Internet connection through our network. In such case, Internet connection would be deemed as a portion of the telecommunications service that enables users to navigate the Internet.

In April 2014, the Brazilian President passed Law No. 12,965/2014, known as the Legal Framework for the Use of the Internet (Marco Civil da Internet), or the Internet Framework, which establishes the principles, guarantees, rights and duties for the use of the Internet in Brazil. Key topics covered in the Internet Framework are: net neutrality; collection, use and storage of personal data; confidentiality of communications; freedom of expression and the treatment of illegal, immoral or offensive contents.

The Presidential Decree No. 8,711/2016 was enacted by the Brazilian President on May 11, 2016 and provided additional detail on the Internet Framework in three main aspects: (i) clarification of the scope and implementation of the net neutrality rules, (ii) implementation of the rights and obligations related to privacy and data protection regarding Brazilian Internet users, and (iii) governance of the Internet Framework, including authorities entitled to enforce the legislations. See “—Review of the Current Regulatory Model for the Provision of Telecommunications Services.”

Privacy and Data Protection

On August 14, 2018, the Brazilian President passed the LGPD. This new law is closer to the European Union General Data Protection Regulation, or GDPR, including significant extraterritorial application and considerable fines of up to 2% of a company’s global turnover of the previous financial year. The LGPD came into effect on September 18, 2020. However, the administrative sanctions provisions of LGPD only became enforceable as of August 1, 2021, pursuant to Law No. 14,010/2020. Cybersecurity incidents and data breach or leakage events may subject us to the following penalties: (1) warnings, with the imposition of a deadline for the adoption of corrective measures; (2) a one-time fine of up to 2% of gross sales of the company or a group of companies or a maximum amount of R$50,000,000 per violation; (3) a daily fine, up to a maximum amount of R$50,000,000 per violation; (4) public disclosure of the violation; (5) the restriction of access to the personal data to which the violation relates, until corrective measures are implemented; (6) deletion of the personal data to which the violation relates; (7) partial suspension of the databases to which the violation relates for up to 12 months, until corrective measures are implemented; (8) suspension of the personal data processing activities to which the violation relates for up to 12 months; and (9) partial or full prohibition on personal data processing activities. The postponement of the administrative sanctions did not prevent the competent authorities to begin supervision procedures and enactment of additional rules to be complied with prior to such effectiveness date, nor did it prevent individual or collective lawsuits based on violation of data subject’s rights and subject to civil liability.

We have set up a team tasked with adapting our processes and technologies to ensure compliance with the LGPD requirements. Notably, we have, among other developments, created a specific clause for the protection of personal data in our contracts with suppliers and business partners, developed training for all employees and customized training for top leadership on the topic of data protection, and created an Executive Data Protection Committee, led by the CEO.

Frequencies and Spectrum Background

In connection with the PCS authorization auctions in 2001 and 2002, Anatel divided the Brazilian territory into three separate regions, each of which is equal to the regions applicable to the public regime fixed-line telephone service providers. PCS services could only be provided under Bands C, D and E at that time with initially 1800 MHz band and afterwards also the 900 MHz band. We acquired the D band in regions II and III and the E band in region I, completing our national coverage when considering TIM Sul, TIM Nordeste and Maxitel coverage (each ultimately merged into the Company). On March 2016, the authorizations for the D and E bands were renewed.

In December 2007, we acquired new authorizations for the 1,800 MHz frequency in São Paulo and Rio de Janeiro in order to improve our RF capacity in these regions. Within the same auction, Claro and Vivo acquired authorizations to provide PCS services in regions where we had historically provided services but where Claro and Vivo previously did not, using 1,800 MHz and 1,900 MHz bands. This resulted in increased competition in these regions. In the same auction, Oi received authorization to provide PCS services in the state of São Paulo using 1,800 MHz (band M in the whole state and band E in the state’s countryside).

In December 2007, we acquired 3G frequencies sub-bands (1,900–2,100 MHz), with national coverage; these authorizations were granted in April 2008 and are valid until 2023. Oi, Claro, Vivo and Algar Telecom also acquired 3G frequencies sub-bands in the same auction carried out by Anatel. All the authorization winners were subject to coverage and/or expansion commitments, divided by Municipality among the winners, in unserved areas.

In December 2010, Anatel auctioned an empty 3G band of radio spectrum consisting of (10+10) MHz in 2.1 GHz in the whole country (the “H Band” Auction), and other left over frequencies in the 900 MHz and 1800 MHz bands that had not been assigned in previous auctions. In this auction: TIM, Vivo, Claro and Nextel (actual America Movil) acquired blocks of frequencies.

In December 2011, Anatel auctioned 16 blocks in the 1,800 MHz band, which were sold to Claro, Oi, CTBC and TIM. As a result of our participation in the auction, we expanded our 2G coverage and increased our presence in the northern and central-western regions of Brazil, including the states of Paraná, Espírito Santo, Rio Grande do Sul, Santa Catarina and Minas Gerais.

In 2012, Anatel established a bidding process in order to comply with Presidential Decree No. 7.512 of June 2011, which set April 2012 as the deadline to auction the 2.5 GHz band, in order to introduce 4G technology in Brazil. Anatel modeled the auction with two national blocks of (20+20) MHz (W and Z) and two national blocks of (10+10) MHz (V1 and V2). In order to guarantee full rural service by 2018, Anatel linked the 4G blocks to the 450MHz band in specific geographic regions of Brazil.

We participated in the auction as a group bidding in the name of TIM and Intelig (now known as TIM S.A.). We did not bid for the W block (Amazonas as a rural area), which we viewed as having a high premium if compared to the X block (67%). We successfully acquired the V1 block, which in our view held the best capital expenditure/operating expenditure profile associated with rural services in its selected regions (the States of Rio de Janeiro, Espírito Santo, Santa Catarina, and Paraná). The joint bid allowed us to take advantage of the flexibility of the auction rules. These bands brought heavy coverage obligations as its short-range characteristics demands large investments.

In November 2013, Anatel approved the dedication of a single band, of the 700MHz spectrum, exclusively to mobile services and in September 2014, Anatel concluded the 700 MHz spectrum auction that granted to TIM, Vivo, Claro and Algar the operation of the 700 MHz frequency for the 4G mobile technology, to be added to the current LTE service in the 2.5 GHz RF. We bid on Block 2 of that auction, for national coverage of the 700 MHz band, and won the same with a bid of R$1,947 million (a 1% premium over the minimum price of R$1,927 million).

The auction also required the winning bidders to proportionally reimburse the broadcasters for the cleanup of the spectrum previously held and used by them. We spent R$1,199 million in order to create in March 2015 the EAD with the other winning bidders, to ensure the spectrum cleanup. The price allocated to the cleanup of the spectrum related to unsold blocks was shared proportionately among the winning bidders who bought the other blocks. To offset such additional cost to the winning bidders, the price of the 700 MHz spectrum was discounted using Anatel’s WACC methodology. As of September 2019, all Brazilian municipalities are able to receive TIM’s expanded 4G coverage through the 700 MHz band. Nevertheless, Anatel must still certify that there has been compliance with spectrum cleaning targets.

In December 2015, Anatel auctioned remaining radio frequencies in the 1,800 MHz, 1,900 MHz and 2,500 MHz bands. We submitted bids for the left over lots of the 2,500 MHz band, which had originally been auctioned in 2012. This particular band spectrum provides for 4G mobile services. We were the first ranked bidder in the lots for Recife, in the state of Pernambuco, and Curitiba, in the state of Paraná, based on our bids which totaled R$57.5 million. The corresponding authorization terms were executed by Anatel in July 2016.

In November 2021, TIM acquired 11 lots in the 5G Auction, with a total value offered of R$1.05 billion, in three frequency bands 3.5 GHz, 2.3 GHz and 26 GHz. The acquired bands have a set of obligations that must be met with financial contributions or the construction of mobile and fixed network infrastructure.

Currently, according to Decree 10,402/2020, which regulates Law 13,879/2019, it is possible to renew licenses for successive periods. However, some conditions are being discussed with Anatel, such as value and term of renewal.

The actual scenario of frequencies granted to us by Anatel is presented on the table below: 

* Terms already renewed for 15 years.

** Only covers complementary areas in the specified states. The Radio frequency Blocks of the Municipalities of the National Code 92, which were part of Lot 208, were returned.

*** Except for the cities in sector 3 of PGO for 3G and excess radio frequency.

Industrial Exploration of Dedicated Lines

In December 2010, Anatel approved a public hearing that considered alterations of the EILD, which established mechanisms for the operation of transmissions circuits up to 34 Mbps to increase transparency between operators and concessionaires. In May 2012, Anatel approved the new EILD regulations (Regulação de Exploração Industrial de Linha Dedicada), or REILD, detailing mechanisms to optimize the operating structure for transmission loop contracts in order to increase contract price transparency and affording equal treatment to independent service providers from concessionaire groups. The REILD specifically sets out more effective rules on project definition including Standard EILD or Special EILD, in addition to contract and delivery terms, and specifies EILD delivery dispute resolution procedures. Concurrently, in May 2012, Anatel approved new EILD reference prices, a step towards value fixation in controversies between service providers.

Considering that EILD is also a market subject to the asymmetric regulation defined by Anatel in the PGMC 2012, operators classified by Anatel as pertaining to group with significant market power in the EILD market, such as Oi, were required to submit reference prices and offers for Anatel’s approval, as well as to only offer EILD through a specific system designed for the PGMC 2012. In September 2013, Anatel ratification, for the first time, reference prices and offers of the operators with significant market power in the EILD market. At least every six months new reference prices and offers must be submitted for Anatel’s approval. We are not currently classified as having significant market power in the EILD market.

Nevertheless, the TIM network is still growing and, with its backbone now reaching the North region of Brazil by using optical fiber technologies and not only via satellite, this has allowed TIM to strengthen and expand the services offered in that region, particularly in the states of Pará, Amapá and the city of Manaus, the capital of the state of Amazonas and a very important industrial zone.

The greatest benefits of the use of the optical fiber technology are the higher network stability and assurance, greater voice and data traffic capacity and the higher transmission rates that we can now provide to our customers, all of which are essential features to support the increasing telecommunication services demands in the region. In addition to these perspectives, we contribute to reduce social disparities, offering the same technology to our customers, as well as content residing locally in our data centers, making no difference to the technical architecture built in a big metropolitan centers.

We have started discussions to apply the EILD reference rates based on cost model to the existing agreements we have with operators with significant market power in the EILD market. As part of the strategy of reducing operating expenses and as consequence of the expansion of our optic network infrastructure we are gradually deactivating leased lines such as EILD. The agreements for network sharing between the national operators is also a key factor to the reducing of leased lines. The number of leased circuits has considerably decreased along the last year. New lines are hired only in the cases where leasing is demonstrated to be the most cost effective solution.

Migration of the Mobile Networks with Analog Technology

In February 2011, Anatel approved Resolution No. 562/11, which modified a provision of the regulation on conditions of use of RF, determining that, after a period of 360 days from the publication, the use of analog technology in RF sub bands of 800 MHz would no longer be allowed.

In relation to the use of such RF, we no longer have subscribers of analog technology. However, our analog networks were still used by STFC concessionaires to provide services to subscribers in rural areas of the country, through a service called RuralCel.

In December 2016, Anatel approved Resolution No. 672/16, which prohibited the use of analog technology in the radio frequency sub bands of 800 MHz, 900 MHz, 1,800 MHz, 1,900 MHz and 2,100 MHz. We shut down our RuralCel service in 2017, and consequently turned off the related radio base stations, as attested to by Oi and recognized by Anatel in Decision-making No. 6/2017.

Quality Management Regulation

In October 2011, Anatel published PCS and SCM quality management regulations to establish quality parameters which were to have been met by the mobile telephone and Internet connection operators in up to 12 months. Most quality parameters established relating to the quality of the networks, both mobile and fixed, became effective in October and November 2012.

In response to the need to better quantify the financial impacts, Oi submitted a request for cancellation together with a request for review to Anatel for the presentation of technical surveys of the economic impacts of the new regulations. The aforementioned request was submitted to public hearing by Anatel, which resulted in a series of divergent opinions regarding the quality measures by the different operations that are being analyzed by Anatel.

With regard to STFC, in December 2012, Anatel approved the Quality Management Regulation for STFC service providers, which aims to create a new quality management model available, such as the Quality for PCS and SCM.

In February 2013, Anatel published the STFC quality management regulations to establish quality parameters that must be met by fixed-line operators within 120 days. All established parameters took effective in June 2013.

In December 2019, Anatel approved the new Telecommunication Services Quality Regulation, (“RQUAL”) based on a reactive regulation. In this new model, quality is measured on the basis of three main indicators – a Service Quality Index, a Perceived Quality Index and a User Complaints Index – and operators are classified into five categories (A to E). Based on this regulation, Anatel will be able to take measures according to specific cases, such as consumer compensation, the adoption of an action plan or the adoption of precautionary measures to ensure quality standard improvements.

At the end of November 2021, after a joint work by Anatel, operators and the Quality Assurance Support Authority to define the objectives, criteria and reference values of indicators, , Anatel’s Board of Directors formalized the reference documents that anchor this regulation (the Operational Manual and the Reference Values) and stipulated that these documents would come into effect on March 1, 2022. Anatel also disclosed the official indexes, and the quality seal (inducing competition for quality) at the beginning of 2023, considering the results of the new monitored indicators in the second semester of 2022. Until then, Anatel will continue to monitor the old indicators that maintain similarity to the new ones established in the new RQUAL. Meanwhile, adjustments in criteria and reference values can be done by Anatel.

Anatel Administrative Proceedings

Under the terms of its PCS authorization, TIM Celular (now TIM S.A.) implemented mobile personal telecommunications coverage for the assigned area. Under such term of authorization, TIM Celular (now TIM S.A.) is required to operate in accordance with the quality standards established by Anatel. If it fails to meet the minimum quality standards required, TIM Celular (now TIM S.A.) is subject to Obligation Non-Compliance Determination Procedures, or PADO, and applicable penalties. Anatel has brought administrative proceedings against the TIM Group, which are currently pending for (1) noncompliance with certain quality service indicators (the quality management regulation, or RGQ, and/or RQUAL); and (2) default of certain other obligations assumed under the Terms of Authorization and pertinent regulations. In its defense before Anatel, the TIM Group attributed the lack of compliance to items beyond its control and not related to its activities and actions. We cannot predict the outcome of these proceedings at this time, but have accrued the amount in our balance sheet as a provision for all those cases in which we estimate our loss to be probable.

C.       Organizational Structure

We are part of the Telecom Italia Group, which is engaged in the communications sector and, particularly, the fixed and mobile national and international telecommunications sector. The operating segments of the Telecom Italia Group are organized according to the respective geographical location of the telecommunications business (Domestic—Italy and Brazil). We are currently held, directly and indirectly, by Telecom Italia, which as of December 31, 2021 held 66.59% of our shares. In turn, the single largest shareholder of Telecom Italia is Vivendi, which holds, directly, a stake of approximately 23.7% of ordinary share capital. In 2019, Telecom Italia delisted all its U.S. listed securities and deregistered from the SEC, having filed Form 15F on July 9, 2019. Substantially all assets previously held by TIM Participações consisted of the shares of the Company (known, until its corporate name change in September 2017, as Intelig, and into which TIM Celular was merged in October 2018 in connection with the Reorganization, as set forth in more detail below) (incorporated in the Federative Republic of Brazil and headquarters located in the State of Rio de Janeiro).

On July 25, 2017, the TIM Participações S.A.’s Board of Directors approved the Reorganization, under which TIM Celular was to be merged into the Company. In connection with the Reorganization, Intelig was transformed by corporate act into a closely held joint stock company and its corporate name was changed to TIM S.A. On October 31, 2018, the Reorganization was concluded and the merger of TIM Celular into the Company was completed, transferring all of TIM Celular’s operations to TIM S.A., and with the Company succeeding to all of TIM Celular’s assets, rights and liabilities. The Reorganization had the objective of capturing operational and financial synergies, through the implementation of a more efficient process structure, as well as accounting and internal control systems. This final step of the Reorganization resulted in efficiencies including: (i) tax efficiencies related to the termination of intercompany transactions; (ii) the creation of one company with combined services (fixed and mobile services) potentially resulting in a more efficient and swift response to the market’s needs, through the development of new services and integrated offers, and enabling a better strategic positioning and competitiveness as well as a better customer experience; (iii) optimization of resources and systems; and (iv) the recording by TIM Participações of an approximately R$952 million tax credit. The minutes of the Reorganization were filed with and approved by the Board of Trade of the State of São Paulo (Junta Comercial do Estado de São Paulo, or “JUCESP”), in December 2018.

On July 29, 2020, our board of directors and the board of directors of TIM Participações approved the Merger of TIM Participações into the Company, which became effective on September 28, 2020. The Merger was part of a reorganization of TIM’s corporate group. The business carried out by TIM following the Merger was the same as the business previously carried out by TIM Participações prior to the Merger. Upon the consummation of this transaction and the approval of the listing of Company’s common shares and ADSs on B3 and NYSE, respectively, TIM Participações S.A.’s shareholders received one share of the Company in exchange for each share of TIM Participações that they held, in accordance with the terms of the Merger Agreement.

On November 16, 2021, IHS acquired a 51% equity interest from us in FiberCo. As a result of the transaction, FiberCo ceased to be our wholly owned subsidiary. We now hold 49% of FiberCo’s share capital and IHS holds the remaining 51%. With the completion of the acquisition, FiberCo changed its corporate name to I-Systems. For more details on this transaction, see “Item 4. Information on the Company—A. History and Development of the Company—2021 Important Events—Completion of the transaction between IHS and I-System."
