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., or TSU, and Tele Nordeste Celular Participações S.A., or 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., or 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, or the AES Atimus Acquisition. In connection with the acquisition, Eletropaulo Telecomunicações changed its corporate name to TIM Fiber SP Ltda., or TIM Fiber SP, and AES RJ changed its corporate name to TIM Fiber RJ S.A., or 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, or 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, or 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, or 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 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. The acquisition process is under evaluation of CADE.

2020 Important Events

Merger of TIM Participações S.A.

On July 29, 2020, the boards of directors of TIM Participações and of the Company approved the Merger, 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 transaction and the approval of the listing of Company’s common shares and ADSs by B3 and NYSE, respectively, TIM Participações S.A.’s shareholders received one share of the Company in exchange for each TIM Participações share that they held, in accordance with the terms of the Merger Agreement.

Capital Expenditures

Capital expenditures totaled R$3,891 million in 2020, up 1.0% as compared to 2019, as found in the Industrial Plan 2020-2022. This increase was due to investments to expand coverage, installing more equipment and fiber.. Approximately 92% of capital expenditures were dedicated to infrastructure, mainly transportation network projects, 4G technology and information technology. The actual amount and timing of our future capital expenditures may be affected by foreign exchange oscillations and other impacts from financial or economic crisis, such as the one arising from the spread of COVID-19. For a detailed breakdown of our capital expenditures in 2018, 2019 and 2020 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 is 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, with the usage of new technologies to achieve localities that were not financially viable or the Massive-MIMO technology; network sharing agreements.

In addition to the assumptions listed above, the process of integrating Oi’s mobile assets, acquired in accordance with the Material Facts published on the market on December 14, 2020 and January 29, 2021, but still pending approval by regulatory bodies, will significantly transform our results, which is why we present a long-term vision focused on the continuity of our operations considering the impacts of the merger.

Recent Developments

FiberCo Formation and Sale of Equity Interest

On December 10, 2020, our Board of Directors approved the formation of FiberCo Soluções de Infraestrutura Ltda., or 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., or IHS, a large and diversified provider of telecommunications infrastructure, to negotiate the terms and conditions for the acquisition of equity interest, by IHS, in FiberCo. As of the date of this annual report, this negotiation is still ongoing.

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 both customer base; 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 implementing the concepts set forth therein 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.

TIM and Fiat Chrysler Automóveis (FCA) connected cars partnership

In October 2020, TIM and Fiat Chrysler Automóveis (FCA) have 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 FCA launches in the country will rely on eSIM, with the LTE coverage quality and TIM's IoT network. As a result, future FCA 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 FCA 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.

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 is scheduled to begin in 2021, and will last until 2022.

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.

Oi Group’s Mobile Assets Acquisition

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, or “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.

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.

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.”

The mobile market has been characterized by the process of migration from prepaid to hybrid (Control plans) and postpaid plans. This movement can be seen as a result of the growing demand for access to data, driven by use of OTT solutions to communicate at no extra cost, and content services. At the same time, the operators sought to retain their customers with offers that are characterized by recurrent consumption and, consequently, of revenue, in line with the strategy of offering more for more.

In 2020, the sector also reflected the tendency toward increased data consumption, requiring operators to adapt their networks and face the challenge of delivering an increasingly robust infrastructure in an environment of more rational investments. Additionally, the industry was marked by increased integration of digital services into portfolios in order to monetize offerings.

Finally, the growing demand for fixed broadband and the strong migration to higher speed service offerings (especially for ultra-broadband, with speeds above 34Mbps) reflected the new perception of Internet access as an essential asset for the population.

Differently from the dynamics perceived on previous years, Brazilian mobile market reported a growth of 3.3% year-on-year (“YoY”). The total base growth pace has been observed for the last time in 2015, when postpaid segment began its consolidation. During 2020, postpaid net additions reached 9.6 million users (63% were human postpaid lines) and surpassed the 2.3 million drop in prepaid users for the first time in five years. With the contraction of the prepaid customer base by 1.9% over the course of 2020, it no longer represents the market’s largest component, constituting 49% of total subscriber base as of December 31, 2020, as compared to 52% as of December 31, 2019. The significant reduction in the overall number of prepaid users is mainly due to acceleration in users consolidating multiple SIM cards to a single one, 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 8.8% during 2020, achieving 51% of total subscriber base as of December 31, 2020, as compared to 48% as of December 31, 2019, driven by operators’ efforts to monetize their customer base, offering more data, content and digital services, and the migrations from prepaid to Control plans, and from entrance plans to postpaid.

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 96% of the country’s population based on Anatel’s coverage criteria.

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

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.

We compete in the corporate telephony business with Nextel, a former provider of digital trunking (based on push-to-talk technology which was discontinued during 2018), or specialized mobile services (serviço móvel especializado), or SME, and currently a regular mobile provider, (significant market power only), using 3G and 4G technology in some regions. Nextel became the fifth mobile telecommunications competitor, but its network deployment was focused mainly in the states of São Paulo and Rio de Janeiro. In 2014, Nextel also entered into a national roaming agreement with Vivo, whereby Nextel’s significant market power customers can use Vivo’s 2G and 3G mobile network in regions where Nextel does not have coverage. In 2019, Nextel Brazil was acquired by Claro S.A.

On November 6, 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.

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.

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 2020, 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.

On July 23, 2019, the Company and Telefônica Brasil also entered into a memorandum of understanding, or 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.

On March 26, 2020, the Company and C6 Bank concluded negotiations regarding a strategic partnership with the objective of developing combined offers with special benefits for their 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, but we have been granted, on February 1, 2021, the right to acquire an indirect equity interest of approximately 1.4% in C6 Bank through the exercise of subscription bonuses, subject to certain agreed upon thresholds.

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), or 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 2020, 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 2020, 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, or IVR, technology – has proven fundamental to improving the customer experience. In 2020, we increased by 9.8% the number of digital customer interactions (an increment of 14% in Mobile App and Website interactions partially set off by a decrease of 36% in IVR interactions). Additionally, the number of individual users of the “Meu TIM” application in 2020 grew 12%, while IVR retention increased by 2.5 percentage points. Also, digital sales in the postpaid segment increased by 32% in the year ended December 31, 2020 as compared to the year ended December 31, 2019, and more than 2% in the prepaid segment, while recharging by digital means continues to become a more relevant sales channel, with a 30% increase in the year ended December 31, 2020 as compared to the year ended December 31, 2019.

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 5 years in a row (2015 - 2020) by the fifth time by the widely circulated newspaper called “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 four 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, 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 will take place during the entire year of 2021.

A Strong brand with a new tagline.

During the 2020 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, after 13 years, TIM again won the TOP OF MIND award from “Folha de SP”, one of the main and most respected and credible media companies in Brazil. In a customer survey, our brand was elected the most remembered in the telecom segment, demonstrating the consistency of the brand and communication work done in the last year.

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, or 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, or 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.

Strong commitment with ESG pillars and the only Brazilian telecommunications company listed on the Novo Mercado

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. 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, or 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 2020, we were listed for the thirteenth 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, and was selected as one of the “top 10” companies on the launch of the S&P B3 Brazil ESG Index in September. In January 2021, TIM was selected to join 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. 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, among others.

As a signatory to the Global Compact since 2008, TIM participates in the Human Rights Working Group organized by the Brazilian Network of the Global Compact since 2015 and promotes projects related to the Sustainable Development Goals (“SDG”). We recognize the rights to data privacy, safe internet, access to information and freedom of expression as essential and unnegotiable.

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). 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.

For 12 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. The Report has an independent third-party limited assurance.

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.

The company also identifies opportunities of improvement to achieve levels of excellence in its Environmental Management System (EMS). It has been working on improving performance in processes and controls since 2010, having obtained ISO 14001 environmental certification for Network Management and Operation in the states of Rio de Janeiro, São Paulo and Espírito Santo.

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 2020, TIM included long-term ESG commitments in its 2020-2022 Strategic Plan. 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 Corporate Governance pillar, while reducing GHG emissions and improving eco-efficiency are relevant Environmental goals. On the Social pillar, the training and the engagement of employees are the main objectives.

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 stock options 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 income tax, depreciation and amortization, or EBITDA, according to our internal analysis, we believe that we have a strong cash flow, a solid financial position and a low relative debt to 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 2023, in a consistent approach with our prior plan (2020-2022). 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. Our aspirations for 2023 reflect these market opportunities and trends, as we will strive to:

Our forward-looking strategy is focused on the four strategic fronts:

In our view, the COVID-19 pandemic increased demand for connectivity and the telecommunications sector has taken advantage of it. 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.

The Brazilian mobile telecommunications market is facing an overall reduction in the number of prepaid customers, as users which previously held multiple SIM cards are consolidating to one single SIM card, the reduction of interconnection charges, which allow companies to offer plans with off-network calls at the same price of on-network calls. In connection with this trend, our strategy is to be chosen as the single SIM provider for the prepaid consumer market by providing offers that are attractive and valuable to customers and 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 while physical stores were closed to maintain sales.

The COVID-19 pandemic crisis led to a drop in prepaid recharge revenue in the first months of the pandemic, recovering in the second half of the year. 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 primary focus on smartphone models that provide for quality Internet access at a low cost. This approach has allowed 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 4G. 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 3G and 4G 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 3,477 cities with 4G technology in 2020, considerably ahead of its competitors. This positions TIM as having the best coverage and the best mobile broadband technology, creating the possibility of an improved market position, particularly for high-end customers. TIM has also reinforced its commitment to cover 100% of the country with its 4G network by 2023. Moreover, TIM has also been strategically investing in 3G technology, achieving more than 3,200 cities covered in 2020. In order to improve our network coverage in an efficient way, without raising investment levels, TIM has executed network sharing agreements during 2020 with other telecommunications providers.

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

TIM Live offers high quality ultra-broadband, with high-speed data connection, currently operating in 34 localities with FTTH (+47.8% YoY), being 27 cities and plus 7 administrative regions of the Federal District. We ended 2020 surpassing 3.2 million homes-passed (HPs) with FTTH (fiber to the home) technology – an expressive double-digit growth of almost 43% when compared to the fourth quarter of 2019 to the fourth quarter of 2020 – and an ARPU increase by 7.8% when compared with 2019.

In 2020, we had a base of 645 thousand clients, adding about 80 thousand customers in the twelve past months (up 14.0% YoY). Net additions to FTTH reached 131 thousand new users in the past twelve months. . We plan to continue expanding TIM Live's services with the right balance between Sales and Capex, reinforcing clusters already launched and accelerating our deployment of fiber (backbone, backhaul and fiber-to-the-home) with fiber-to-the-home offered in selected regions. Our success with TIM Live has been the result of the strategy of offering a differentiated autonomous broadband service, with an OTT friendly approach.

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.

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 and by WhatsApp. Customers can also recharge straight from their mobile handsets using credit cards.

Consumer Plans

In 2020, 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

·        TIM Pré TOP: Offerings launched during 2020 were built for provide a full experience with simplicity, by adapting consumption according to balance and recharge; boosting benefits (unlimited network calls, unlimited calls for other carries using code 41, adaptable data packages and SMS). In addition, due to the more aggressive competition scenario, we have become more competitive, giving more benefits to customers with a high recharge value and expanding the monthly R$20,00 offer to more area codes.

·        TIM Beta: With an exclusive feel, this plan focused on young and digital customers that can only enter by invitation send by existing members or participating in a journey and accomplishing tasks to conquer their own invite. Until the end of 2020, the plan offered voice, SMS and data packages per day, week or month. However, in December, there were changes in the plan with the end of the commercialization of daily and weekly offers. New monthly offers were launched with more attractive service packages that include 8GB of internet franchise for Netflix, YouTube, Instagram and TikTok and unlimited calls.

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.

We are seeking to increase customer base loyalty within the Controle segment by offering discounts for a 12-month contract; this type of offer allows TIM to be more competitive while taking a selective and rational approach. We also offer an innovative unlimited data “plug in” at a price of R$20.00 for use of social networks, and give customers the opportunity to “try and buy” this social network plug in for three months. We launched a new higher tariff plan within TIM Controle set at R$79.99 with unlimited access to social networks, 5.0 GB Internet and unlimited calls in order to encourage customers to upgrade after the try and buy period.

Corporate Plans

In 2020, 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.

Additionally, 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.

Value-Added Services

We are constantly seeking to increase value to our customers through innovative offers and products, and 2020 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 relevant change regarding Value-Added Services in 2020 was the improvement of our portfolio through additional services provided by new strategic partners. For 2021, we intend to continue to implement this strategy in a wider array of products, to introduce new types of Value-Added Services into these bundles, and to launch a new strategy to sell stand-alone Value-Added Services offers which will focus on aligning clients with Value-Added Services offerings.

Financial and Other Services

In 2020, 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, such as TIM Protect, a value added services insurance plan that covers certain device damages, losses and theft. For 2021, we intend to develop new partnerships with Brazilian fintechs in order to provide agility and innovation to our customers.

Digital Channels

In 2020, we focused our efforts in the evolution of digital channels (including public and logged web sites, self-caring applications and e-commerce portals) in order to deliver new services, provide better customer experience

and operate with more efficiency. Digital channels usage volume has increased significantly in 2020, with more visits in the public website and increases in the total sales and users of the Meu TIM application as compared to 2019.

In addition, we are able to interact with our customers through WhatsApp, a channel that is already integrated into their digital life. We are the first Brazilian operator to close a commercial contract to use WhatsApp Business, which allows communication between companies and customers in a simple and easy way.

Customer Service

In order to serve our customer base, almost 55 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 18 customer care centers, two of our own and eight outsourced, comprising around 10,511 customer service representatives (of which 1,888 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, 2020, we had more than 11.8 thousand points of sales through premium shops and dealers (exclusive or multi-brand) and consolidated partnerships with large retail chains. This figure includes 161 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 220 thousand points of sale throughout Brazil.

For the corporate market, TIM has more than 536 third-party business partners and 112 employees focused on serving small- and medium-size companies and a direct sales force team of 86 employees focused on large companies.

Throughout 2020, 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.

In 2020, 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 transversal competences, but also on new capabilities. 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” improved by 3pp (87%), from 2019 to 2020. Compared to the other telecom companies that also use this survey, TIM is 12pp (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).

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.

Interconnection Charges

We receive interconnection revenues in connection with any call 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.

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. In 2004, Anatel issued regulation establishing that the agency would determine rules for the calculation of reference rates for interconnection fees based on a cost model. Transition rules were defined and applied until, in July, 2014, by means of 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. 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 selection program, 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. Other long distance carriers, in turn, pay us a VU-M fee for any use of our network for a long distance call.

As determined by Anatel, our long distance usage rate categories are as follows:

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, mainly 4G equipment that provides Dual SIM, near-field communication, WiFi, Internet, Bluetooth and camera functionalities, while practicing a policy of increasing 4G smartphone penetration, focusing on high quality 4G smartphones to enhance the customer experience. Our mobile handsets can be used in conjunction with either our prepaid or postpaid service plans. In 2020, TIM furthered its focus on postpaid and TIM Controle segments, offering to these customers discounts on 4G smartphones. Currently, we believe that supplies of mobile handsets are sufficient to satisfy demand, but also plan to expand our mobile handset portfolio to new devices focused on the customer experience, such as routers, other web devices and accessories.

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, or when a postpaid customer does not pay the first or second invoice, 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. Our Express Plan has also proved to be an important tool to prevent early delinquency, since the payments are made by credit card.

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.” Currently, the roaming reconciliation process is largely managed by industry sponsored groups, while the interconnection reconciliation process is primarily managed directly by us.

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 3,877 cities to 95.2% of the urban population of Brazil, making our 4G network the most extensive in the country. Our 3G coverage reaches 3,506 municipalities and 92.8% of the urban population. We also offer GSM telecommunications services with a national reach to 95.2% of the urban population, which is one of the most extensive GSM coverage areas in Brazil, with a presence in 3,476 municipalities.

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 96% 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, 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. See “—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 2020, we made R$3,891 in investments, of which 91.2% of our capital expenditures were in infrastructure, primarily in 4G and 3G deployment, expansion and capacity enhancement of our optical transport networks, 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 2020, the milestone of 3,877 cities with 4G coverage, or 95.2% 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 April 30, 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.

Our wireless network has both centralized and distributed functions, and includes mainly transmission equipment, consisting primarily of more than 143 thousand eNodeBs in our 4G network, more than 20 thousand NodeBs for the 3G layer and more than 13 thousand BTSs for 2G network as of December 2020, 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 2020, we continued to increase the quantity of sites connected by optical fiber, contributing to an increase in data carried on our network as compared to 2019. The results are consistent with Anatel’s network quality requirements, and with TIM retaining its solid performance in 2020. 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 30 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.

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 2020, 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 11 new virtualized Edge Network Datacenters (DCE) located in Campinas, Porto Alegre, Natal, João Pessoa, Florianópolis, Blumenau, Maringá, Londrina, São Luis, Goiânia 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

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, or 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 in case of unexpected events 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, even in case of unexpected events.

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). On April 30, 2020, the Company obtained the approval of the Anatel and, on June 3, 2020, obtained the approval of the Administrative Council for Economic Defense (Conselho Administrativo de Defesa Econômica), or 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.

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 that TIM, Claro, Oi and Vivo guarantee the provision of mobile services (voice, SMS and data) in all cities with less than 30,000 inhabitants. The project started with trial service in 35 cities (8 for TIM, 9 for Claro, 9 for Oi and 9 for Vivo), which has already been implemented. Following the trial period in 2018, TIM has expanded its coverage to 613 new cities which means now its coverage encompasses a total of 1,966 cities.

International Roaming Agreements

We have international roaming agreements available in 210 different countries with 423 international operators that encompass 620 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 2020, we expanded our 4G data coverage to 74 new networks, meaning now we offer 4G roaming in 81 countries, covering the main travel destinations for Brazilians.

In July 2019, an agreement was entered into among the Mercosur countries to eliminate international roaming charges among them, and instead charge users of mobile services (voice and data) traveling throughout the Mercosur countries according to the plan contracted in their home country, without additional charges. In Brazil, the agreement must still be approved by the Brazilian Congress and will only be valid after two or more countries have ratified the agreement before the secretariat of Mercosur. In November 2018, Brazil also entered into a free trade agreement with Chile, which resulted in the end of international roaming between the two countries. This agreement is also pending approval by the Brazilian Congress. In 2021, Anatel was expected to set up technical groups to discuss the details of the implementation of both the Mercosur agreement and the Chile free trade agreement, which have been delayed due to the COVID-19 pandemic.

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.

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 2013, Anatel enacted Resolution No. 95, which regulates FUNTTEL collection. As in the case of FUST, it requires that FUNTTEL be calculated based upon revenues arising from interconnection charges since its effectiveness. Sinditelebrasil, the Brazilian syndicate of telecommunications companies, filed a Writ of Mandamus against Anatel in order to compel Anatel not to apply Resolution No. 95/2013. An injunction was issued in our favor and a favorable final decision was issued by the Federal 1^st Region High Courts of Appeal.

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, or EBC, or the Brazilian National Cinema Agency (Agência Nacional do Cinema), or 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.

The FISTEL fee to be paid in 2020 was deferred due to Provisional Measure No. 952, enacted in April 15, 2020. Therefore, up to December 31, 2020, the FISTEL fee was not paid based on an injunction issued by the Regional Court of the 1st Region.

In 2013, the Brazilian government enacted Provisional Measure No. 627/2013, in order to end the Transitional Tax Regime, or RTT. RTT was implemented in 2008 as a way to neutralize the tax impact caused by the adoption of IFRS accounting rules in lieu of Brazilian GAAP.

In 2014, Provisional Measure No. 627 was converted into Law No. 12,973, the main objective of which was to implement the new tax regime, adapted to the new accounting guidance provided by IFRS, ending the RTT. Given that the implementation required specific adjustments to promote the elimination of the effects of registration of the new accounting methods and criteria to the statutory books, some assets and liabilities now have different methods and accounting criteria from those previously adopted by the former accounting rule. Law No. 12,973 established as a condition for the accurate tax treatment of these differences to impact only at the time of the realization of these assets or liabilities the creation of subaccounts for individualized control. The treatment is the same in regard to present value adjustments and fair value adjustments.

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 2020. Please refer to “Item 4. Information of the Company—2020 Important Events—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, or 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 No. 3,000/1999 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 dasComunicações), or Minicom, former Ministry of Science, Technology, Innovation and Communication (MCTIC). Anatel is responsible for promulgating standards related to telecommunications services and regulating the relationship between different operators, 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), or PGMU I, creating landline universal service obligations binding on the landline telephony services (Serviço Telefônico Móvel Comutado), or STFC, concessionaires. PGMU is reviewed every 5 years regulating obligations such as public pay phones and telephone services for low income. In December 2018, PGMU IV was published 2 years late and included obligations to deploy 4G fixed wireless access in non-urban districts. In addition, there was a reduction in the obligation to maintain and deploy payphones.

The last universalization plan formulated by the government, considering that fixed telephony concession end in 2025, was published in January, 2021. The PGMU V, replaces the 4G targets, established in PGMU IV, with the construction of a backhaul in the municipalities that do not yet have an optical fiber 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.

In November 2012, Anatel enacted PGMC 2012, whose goal is to encourage competition by creating interconnection obligations and the sharing of infrastructure already installed by other operators. PGMC 2012 was amended by Resolution No. 694/2018, the New PGMC. Full adoption of these standards required new investments and has been under debate.

In March 2014, by means of Resolution No. 632/2014, Anatel approved the adoption of a single regulation for the telecommunications sector (Regulamento Geral de Direitos do Consumidor de Serviços de Telecomunicações),

or 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. In December 2020, Anatel initiated the public consultation 77 in order to review Resolution 632/2014. The public consultation received contributions until April 21, 2021 and new regulation is expected to be approved in the 2^nd half of 2021.

In 2016, Anatel issued certain regulations which are particularly relevant to our operations, including: Resolution No. 663/2016, which modified rules for mobile virtual network operators; Resolution No. 667/2016, which approved the General Regulation of Accessibility in Telecommunications Services of collective interest; Resolution No. 668/2016, which modified the STFC Regulation; and Resolution No. 671/2016, which approved the Regulation on the Use of the Radio frequency Spectrum and modified the Regulation on the Collection of Public Price for the Right of Use of Radio frequencies and the Regulation on the Imposition of Administrative Sanctions.

In 2018, Anatel also issued several resolutions that are material to our business in certain respects. Resolution No. 693/2018 approved the new General Interconnection Regulation and revoked the “General Interconnection Regulatory Framework” set forth by Anatel in 2005. Resolution No. 695/2018 approved the new Public Price for the Right to Use of Radio Frequencies, or PPDUR, setting forth a two-part price calculation basis, one for renovation of radio frequencies and the other for license acquisition. Resolution No. 702/2018 reduced the authorization fee to R$400.00 for all telecommunication services. Resolution No. 703/2018 set forth a new cap for spectrum usage limits and allowed a given player to retain more spectrum bandwidth (30% to 40% of the total available spectrum).

In March 2018, the E-Digital Decree (Decree No. 9,319/2018) was published by former MCTIC in order to identify around 100 strategic actions aimed at boosting competition and online productivity levels in Brazil, while raising connectivity and digital inclusion levels. The actions seek to address the main strategic issues for the digital economy, including connectivity infrastructure, the use and protection of data, IoT, and cyber-security. The E-Digital Decree sets out approximately 100 strategic actions aimed at increasing competition and online productivity levels in Brazil, as well as the increasing connectivity and digital inclusion levels of the Brazilian population as a whole. These actions cover strategic topics related to the digital economy, including infrastructure connectivity, privacy and data protection, IoT and cyber-security.

In 2019, Anatel issued several important regulations that have a significant impact on our operations, particularly Resolution No. 709/2019 which approved the General Numbering Regulation, Resolution No. 710/2019 which approved the allocation of the 2.300 GHz radiofrequency band to the SLP and the Regulation on Conditions of Use of the 2,300 GHz radiofrequency band, Resolution No. 711/2019 which approved the allocation of the 3,500 GHz radiofrequency band and the Regulation on Conditions of Use of the 3,500 GHz radiofrequency band and the Resolution No. 717/2019 which approved the new Regulation on the Quality of Telecommunication Services – RQUAL aiming to reflect more accurately the quality conditions experienced by consumer.

In 2019, the Brazilian Government published a document titled the Public Consultation on a Brazilian Strategy for 5G Network, or the 5G Strategy. The objective of the government was to base a policy on a diagnosis of the challenges, a vision of the potentialities and a map of the opportunities offered by 5G in Brazil. The document was divided into five thematic axes: (i) radiofrequency and licensing; (ii) research; (iii) development and innovation; (iv) applications; and (v) security in the 5G environment.

In June 2019, the Decree on the National Plan for Internet of Things (Decree No. 9,854/2019) was published in order to regulate and encourage this technology in Brazil. It refers to IoT as “the infrastructure that integrates the provision of value-added services with physical or virtual connection capabilities of things with devices based on existing information and communication technologies and their evolution, with interoperability.” The decree lists the following subjects as required to further support the National Plan for Internet of Things: (i) science, technology and innovation; (ii) international insertion; (iii) vocational education and training; (iv) connectivity and interoperability infrastructure; (v) regulation, security and privacy; and (iv) economic viability.

Telecommunications Self-regulation System

In September 2019, the main telecommunication operators in Brazil compromised on a self-regulation Code of Conduct on Telemarketing. Such initiative was adopted in March 2019 and since July 16, 2019 consumers can register on specific website to restrict telemarketing calls from telecommunication operators.

In March 2020, telecommunication operators signed the Telecommunications Self-Regulation System, or SART, and approved two codes: Attendance and Offers. A code regarding billing obligations are still under discussion by the telecommunication operators and SART independent advisors.

Throughout 2020, the Federal Government and Anatel issued other important public consultations and decrees as listed below:

Federal Government

In 2020, several important Decrees were published, of which we highlight: (i) Decree No. 10,222/2020 was published in February and established the National Strategy for Cyber Security (E-Ciber). The E-ciber is the first module of implementation of the National Information Security Policy (Decree 9.367/2018) and contains the main actions intended by the federal government in the area of cyber security from 2020 to 2023; (ii) Decree No. 10,332/2020 which provides for Digital Government Strategy for the period as from 2020 to 2022, by means of use of information and communication by agencies and entities of the direct, autarchic and foundational federal public administration; (iii) 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; (iv) Decree No. 10,534/2020 to institute the National Innovation Policy, within the scope of the federal public administration, aiming to stimulate the research, development and innovation of companies, ICT and private non-profit entities with a view to increase the productivity and competitiveness of the economy, the generation of wealth and the good -being social; and (v) Decree No. 10,526/2020 that institutes a Committee for Infrastructure Planning and Long-Term Integrated Infrastructure Plan.

Anatel

In 2020, Anatel submitted 78 topics for public consultation. The main topics were: (i) Public Consultation No. 5 – Resolution Draft approving the Adaptation Regulation for STFC Concessions; (ii) Public Consultation No. 9 – 5G Auction; (iii) Public Consultation No. 19 – Regulation of Continuity of STFC – Reversible Assets; (iv) Public Consultation No. 25 – to collect subsidies on reinforcers / repeaters of signals of SMP; (v) Public Consultation No. 37 – Proposal for Telecommunications Services Numbering Regulation; (vi) Public Consultation No. 48 – White Spaces; (vii) Public Consultation No. 51 – to collect subsidies to revise Regulations for the Use of Radio Spectrum; (viii) Public Consultation No. 65 – Simplification of regulation of telecommunications services; and (ix) Public Consultation No. 77 – General Regulation on Consumer Rights (RGC).

Additionally, Anatel enacted several important regulations that will have a significant impact on our activities, particularly those summarized below:

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

In April 11, 2016, the working group composed by MCTIC and Anatel published its final report with a “diagnosis” on the telecommunications industry and proposed guidelines for the revision of the Brazilian regulatory model. A bill of law (PLC 79/2016) was then presented to the National Congress of Brazil to propose amendments to the General Telecommunications Law.

Law No. 13,879 was approved in 2019 and 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.

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.

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]

The following table shows each of our authorizations in effect on December 31, 2020:

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 2019, Anatel approved RQUAL, which is expected to enter into force in 2021. RQUAL will apply to all telecommunication services (mobile, fixed, fixed broadband and payTV). Under this new model, service quality is measured based on three indicators (Quality of Service Index, Perceived Quality Index and User Complaint Index) and it classifies operators according to performance. It also establishes a mandatory ombudsman. Anatel will be able to adopt case-by-case remediation measures, such as consumer compensation (based on a user compensation model), adoption of an action plan or adoption of precautionary measures in order to ensure the improvement of quality standards. It also grants customers additional rights including the customer’s possibility of terminating their service agreement without penalty in case of poor service quality. The new regulation is expected to enter into force in 2021. Until the working group is formed by Anatel, operators and electronic self-assessment questionnaires, or ESAQs, shall define the goals, criteria and reference values for quality control and remediation measures. Anatel will monitor the indicators similar to the new ones established under RQUAL. The criteria and reference value shall be determined in the coming 12 months by the working group.

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.”

Since 2018, 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” are 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$627 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 366 cities with less than 30 thousand inhabitants thus reaching over 3.4 million people. 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. However, on April 13, 2021, Anatel approved our request to anticipate the deployment of such infrastructure, which is now expected to be concluded in two years.

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 two new markets: (i) interconnection for telephone traffic in fixed networks; and (ii) 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.

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.

Also in 2005, Anatel issued a ruling for “Accounting Separation and Cost Accounting,” introducing the obligation of presenting the Accounting Separation and Allocation Document (Documento de Separação e Alocação de Contas), or DSAC, by the license holders and groups holding significant market power in the offering of fixed and/or mobile network interconnection and wholesale leased lines (Industrial Exploration of Dedicated Lines (Exploração Industrial de Linha Dedicada), or EILD). Starting from 2006 (for fixed operators) and 2008 (for mobile operators related to the results of 2006 and 2007), operators (TIM included) are delivering the requested information to Anatel.

In 2013, Anatel reviewed almost the entirety of DSAC. Pursuant to Resolutions No. 608 and 619, the level of information to be delivered to Anatel and the number of products analyzed were extended. Rules on costs allocation were also standardized in order to allow comparison of the results among operators.

With respect to mobile interconnection, in October 2011, Anatel established a mechanism for reducing fixed-to-mobile call rates, applying a reduction of 18% in 2012 and 12% in 2013. In November 2012, through Resolution 600, Anatel decided that the VU-M reference rates in 2014 would be 75% of the valid VU-M in 2013, and in 2015 by 50% of the valid VU-M in 2013. Based on that, in December 2013, VU-M prices for 2014 and 2015 were published 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. After 2019, the VU-M will be charged by the significant market power whenever their network is used to originate or to finish a call. 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 2019 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 2021. 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. Pursuant to Anatel’s rule, reference rates will decline based on a glide path until the cost modeling known as BU-LRIC is applied (2019, for VU-M and TU-RL; and 2020, 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 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.

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 will only become enforceable as of August 1, 2021, pursuant to Law No. 14,010/2020. Once the administrative sanctions of the LGPD become enforceable, 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 does not prevent the competent authorities to begin supervision procedures and enactment of additional rules to be complied with prior to such effectiveness date, nor does 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 lectures 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).

We requested a renewal of our authorizations for the D and E bands (1,800 and 900 MHz frequencies) in September 2013, given that the initial term for which the authorization was expiring. The process was reviewed by Anatel, which handed down a decision based on formal legal opinion by the Federal Attorney General on the matter. According to such decision, TIM was entitled under the current rules to a renewal of our authorizations for the D and E bands, which started on March 2016.

In December 2007, we acquired new authorizations for the 1,800 MHz frequency in the 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:

In December 2011, Anatel started auction No. 001/2011-PVCP/SPV, pursuant to which 16 blocks in the 1,800 MHz band 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. Our corresponding RF authorization periods were formalized with Anatel in May 2013.

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.

The Authorization Terms for usage of the 700 MHz spectrum were signed in December 2014 and the Articles of Association and By-laws of EAD were filed on March 2, 2015. Our EAD payments were completed in January 2018.

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.

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.

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 (AMPS). 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 RQUAL, which is expected to come into force in 2022. RQUAL will apply to all telecommunications services (mobile, fixed, fixed broadband and pay TV). In this new model, in addition to the mandatory establishment of an ombudsman, the quality of service is measured based on three indicators (Service Quality Index, Perceived Quality Index and User Complaint Index), classifying operators according to their performance. Anatel may adopt remedial measures on a case-by-case basis, such as compensation to the consumer (based on the user's compensation model), adoption of an action plan or adoption of precautionary measures to ensure the improvement of quality standards. The new regulation also gives customers additional rights, including the possibility for the customer to terminate their service contract without penalty in the event of poor service quality. The forecast is that the new regulation will come into force in 2022. Until the work group formed by Anatel,

operators and ESAQ (Support Entity and Quality Measurement), define the goals, criteria and reference values for control measures of quality and remediation, Anatel will monitor indicators that are similar to those established in RQUAL.

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.

Disclosure Pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 added Section 13(r) to the Exchange Act. Section 13(r) requires an issuer to disclose in its annual or quarterly reports filed with the SEC whether the issuer or any of its affiliates has knowingly engaged in certain activities, transactions or dealings with the Government of Iran, relating to Iran or with designated natural persons or entities involved in terrorism or the proliferation of weapons of mass destruction during the period covered by the annual or quarterly report. Disclosure is required even when the activities were conducted outside the United States by non-U.S. entities and even when such activities were conducted in compliance with applicable law.

We are also required to disclose our affiliates’ activities relating to Iran and Syria. The Company has entered into Roaming Agreements for the provision of telecommunication services with mobile telephone network, or MTN, from Iran and Syriatel from Syria.

In accordance with our Code of Ethics, we seek to comply with all applicable laws. The Code of Ethics is available on our website: www.tim.com.br/ir.

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, 2020 held 66.59% of our shares. In turn, the single largest shareholder of Telecom Italia is Vivendi, which holds, directly, a stake of approximately 23.75% 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.

The following chart illustrates our current ownership structure:

D.       Property, Plant and Equipment

Our principal properties consist of radio frequencies, transmission equipment, switching exchanges and gateway equipment, which connect calls to and from customers and enables data traffic connections, and radio base stations, which comprise certain signal transmission and reception equipment covering a defined area. At our radio base station, we have also installed antennas and certain equipment to connect these antennas with our switching equipment. As of December 31, 2020, we had more than 43 thousand eNodeB, more than 20 thousand NodeB, more

than 15 thousand BTS and more than 108 thousand kilometers in fiber optic networks. We generally lease or buy the sites where our mobile telecommunications network equipment is installed. Over the course of financial year 2020, we had leased approximately 108,547 square meters of real property, all of which was available for office space.
