INDEPENDENT AUDITOR’S REVIEW REPORT ON QUARTERLY INFORMATION

The shareholders, board of directors and officers

TIM S.A.

Rio de Janeiro - RJ

Introduction

We have reviewed the accompanying individual and consolidated interim financial information, contained in the Quarterly Information Form (ITR) of TIM S.A. (“Company”) for the quarter ended March 31, 2021, comprising the balance sheet as of March 31, 2021 and the statements of income, comprehensive income, changes in shareholders’ equity and cash flows for the three-month period then ended, including the explanatory notes.

Management is responsible for preparation of the individual and consolidated interim financial information in accordance with NBC TG 21 – Demonstração Intermediária, and IAS 34 – Interim Financial Reporting, issued by the International Accounting Standards Board (IASB), as well as for the fair presentation of this information in conformity with the rules issued by the Brazilian Securities and Exchange Commission (CVM) applicable to the preparation of the Quarterly Information Form (ITR). Our responsibility is to express a conclusion on this interim financial information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and international standards on review engagements (NBC TR 2410 and ISRE 2410 - Review of Interim Financial Information performed by the Independent Auditor of the Entity, respectively). A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with auditing standards and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion on the individual and consolidated interim financial information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying individual and consolidated interim financial information included in the quarterly information referred to above are not prepared, in all material respects, in accordance with NBC TG 21 and IAS 34 applicable to the preparation of Quarterly Information Form (ITR), and presented consistently with the rules issued by the Brazilian Securities and Exchange Commission (CVM).

Other matters

Statements of value added

The quarterly information referred to above includes the individual and consolidated statements of value added (DVA) for the three-month period ended March 31, 2021, prepared under the responsibility of the Company's management and presented as supplementary information for IAS 34 purposes. These statements have been subject to review procedures performed in conjunction with the review of quarterly information to conclude that they are reconciled with interim financial information and accounting records, as applicable, and if their form and content are consistent with the criteria defined in NBC TG 09 “Statement of Added Value”. Based on our review, we are not aware of any fact that leads us to believe that these statements of value added were not prepared, in all material respects, in accordance with the criteria established in the Technical Pronouncement and is consistent with respect to the individual interim financial information and consolidated taken as whole.

Financial Performance (Including the effects of IFRS 9, 15 and 16)

OPERATING REVENUE

13

2021 First Quarter Results

Breakdown of Mobile Segment (net of taxes and deductions):

Mobile Service Revenues (MSR) totaled R$3,947 million, up by 2.8% compared to 1Q20, almost doubling growth pace when compared to 4Q20 figures (+1.5% YoY), due to better performances both in prepaid and postpaid segments.

Breaking down each mobile segment in the first quarter:

| (i) | Prepaid segment, although impacted by the worsening of the pandemic, maintained the gradual recovery seen in the beginning of the second half of 2020. Rechargers improved in 1Q21, reaching positive figures in March in a yearly comparison. The increased penetration of TIM Pré TOP has contributed to a stronger recurrence and expansion of the segment’s ARPU. All effects combined, Prepaid Revenues dropped 4.1% YoY, reducing losses versus the drop recorded in 4Q20 (-4.9% YoY).

| (ii) | Postpaid segment’s recovery has been reinforced by continuous focus on a “Value” approach, emphasizing churn management and an offer portfolio geared towards ARPU increase. In 1Q21, human postpaid churn stood at 2.7% per month, contributing to positive net additions. Postpaid Revenues grew 3.9% YoY in the quarter.

ARPU’s (Average Monthly Revenues per User) dynamics continues to drive MSR growth. Consolidated mobile indicator grew 6.6% YoY and reached R$25.5, reflecting TIM’s successful efforts to monetize its customer base through migrations to higher value prepaid and postpaid plans.

The segments' ARPU, which excludes Other Mobile Revenues and Customer Platform, increased in prepaid by 3.9% YoY and by 1.9% YoY in postpaid (ex-M2M).

In 1Q21, Interconnection Revenues (ITX) grew 22.0% YoY, reflecting the impact from a higher MTR rate (Mobile Termination Revenue +17.2% YoY) in addition to an increase in incoming traffic (+30.5% YoY). The incidence of MTR on Net Service Revenues reached 2.6% in the quarter.

14

2021 First Quarter Results

Customer Platform Revenues totaled R$ 17 million in 1Q21, of which R$ 11 million were generated by Financial Services, and R$ 6 million from Mobile Advertising (the latter being the first quarter recording revenue and helped by the evolution of platforms such as TIM Ads and Informa TIM).

The Other Revenues line was up by 10.2% YoY in 1Q21, mainly due to increased revenues from network sharing and swap agreements, in line with the company's strategy to expand the fiber optic transport infrastructure (backbone and backhaul) with higher efficiency in asset allocation (Capex and Opex).

Breakdown of Fixed Segment (net of taxes and deductions):

Fixed Service Revenues totaled R$ 281 million in the quarter, a 12.1% increase from 1Q20. This performance continues to reflect TIM Live’s performance, which rose 20.4% YoY in 1Q21 and continued to account for approximately 62% of fixed service revenues. Other fixed services were up by 0.8% YoY. At the end of the quarter, TIM Live was present in 27 cities and 7 administrative regions of the Federal District. |  |

|  | TIM Live’s ARPU (Average Monthly Revenues per User) was up by 6.1% YoY. The performance is explained by the penetration of higher-value FTTH offers with faster speeds (connections over 100 Mbps accounts for 50% of customer base) and price readjustments as of July 2020 in most plans.

15

2021 First Quarter Results

OPERATING COSTS AND EXPENSES

Reported Operating Costs and Expenses totaled R$ 2,319 million in 1Q21 (+1.5% YoY). This performance is slightly impacted by non-recurring items accounted in 1Q20 – in the amount of R$ 2.6 million – related to adjustment to towers’ sale-leaseback contract. In this quarter, the line was not impacted by non-recurring expenses.

Breakdown of Costs and Expenses Performance:

Personnel Costs increased by 8.0% YoY in 1Q21. This performance was mainly influenced by organic elements, such as inflation on wages and benefits and increased expenses with labor contingencies in social security proceedings.

Selling and Marketing Expenses were up by 1.6% YoY in 1Q21, mainly impacted by higher product marketing and advertising expenses, derived from increased media exposure, and higher FISTEL expenses. This was partially offset by efficiency gains from process digitalization and higher penetration of digital channels and a scenario of reduced sales in the yearly comparison, with lower commissioning expenses from rechargers and line activations.

The Network and Interconnection group rose 14.8% YoY in 1Q21, boosted by higher costs from the interconnection subgroup (ITX), mainly explained by: (i) a higher mobile termination rate (MTR) as from February 2021; and (ii) increased pressure of outgoing traffic to other operators due to the pandemic. Network expenses also increased in 1Q21, stemming from higher costs in infrastructure sharing contracts, compared to an improvement to energy costs.

16

2021 First Quarter Results

Normalized General and Administrative (G&A) Expenses were up by 5.9% YoY in the quarter. This increase is mostly explained by the net effect of: (i) higher IT maintenance and rental expenses; and (ii) lower expenditures with professional services (especially legal), and cleaning/surveillance regular services and transportation.

Cost of Goods Sold (COGS) totaled R$ 146 million in 1Q21 (-8.3% YoY), following the drop in Product Revenue due to a lower volume of handset sales, despite the increase in higher-value product mix. The performance mainly reflects the closing of TIM’s brick-and-mortar stores (the Company’s main handset sales channel) during March, due to measures to contain COVID-19 in Brazil.

In 1Q20, the Provisions for Doubtful Accounts (Bad Debt) fell 34.5% YoY, the fourth consecutive quarter with a yearly drop, showing the continuous efforts to enhance customer acquisition through more robust credit models and policies, and higher efficiency in collection and recovery. In absolute figures, Bad Debt came to R$ 123 million, accounting for 2.02% of TIM’s Gross Revenue.

Normalized Other Operating Expenses1 were down by 21.6% YoY in 1Q21, explained by (i) reduced expenses from losses with civil and labor lawsuits; and iii) increased provisioning for labor lawsuits, partially offset by a lower spending with civil lawsuit provisions. This line’s share over the quarter’s total normalized Opex stood at 3.0% in 1Q21 (versus 3.9% in 1Q20).

Subscriber Acquisition Costs (SAC = subsidy + commissioning + advertising expenses) totaled R$ 52.1 per gross addition in 1Q21, down by 12.6% YoY, impacted by the higher M2M gross additions volume in 1Q21 compared to 1Q20.

|  | The SAC/ARPU ratio (payback per client) fell YoY, reaching 2.0 months from 2.5 months in 1Q20.

1 The Other Operating Expenses line had negative non-recurring impact in 1Q20 (R$ 2.6 million), related to adjustments to towers’ sale-leaseback contract.

18

2021 First Quarter Results

DEPRECIATION AND AMORTIZATION (D&A) / EBIT

In 1Q21, D&A was up by 1.4% YoY, explained by increased Depreciation of 4G equipment and right of use related to a larger lease agreement base, even though it was offset by lower software amortization.

Normalized EBIT3 in 1Q21 grew 12.8% YoY, reflecting EBITDA growth. Normalized EBIT Margin ended the quarter at 13.7%, 1.2 p.p. up compared to 1Q20.

NET FINANCIAL RESULTS

Net Financial Results in 1Q21 were negative by R$ 225 million, R$ 26 million better than 1Q20. This difference is mainly related to lower financial expenses from the net effect of: (i) lower spending with interest from financing, lower expenses from the monetary restatement of civil and labor contingencies; and (ii) higher volume of interest on leasing.

INCOME TAX AND SOCIAL CONTRIBUTION

In 1Q21, Reported Income Tax and Social Contribution totaled -R$ 90 million, compared to -R$ 99 million in 1Q20, the reduction is mainly due to the higher use of tax benefits in 1Q21. On a Normalized basis, there was a ~R$ 9.0 million reduction in 1Q21 when compared to -R$ 99 million in 1Q20, for the reasons already explained above, considering the absence of relevant non-recurring effects. In 1Q21, the effective rate stood at -24.6% vs. -36.0% in 1Q20 (on a Normalized basis).

NET INCOME4

2021 First Quarter Results

CASH FLOW, DEBT AND CAPEX

In 1Q21, EBITDA-Capex came to R$ 696 million, a decrease of 32.4% YoY, taking EBITDA-Capex over Net Revenues to 16.0% (vs 24.4% in 1Q20).

In an exercise to exclude the leases effects from these indicators, 1Q21 EBITDA was recalculated considering the impact of the lease contracts over the operating expenses. Therefore, EBITDA-AL (After Lease) minus Capex would sum up to R$ 235 million (-60.7% YoY).

CAPEX

Capex totaled R$ 1,324 million in 1Q21, up by 46.5% compared to 1Q20. The hike is mainly explained by the return of investments after two quarters impacted by project reevaluation due to the pandemic. Additionally, the company has begun to prepare itself for the integration of Oi Mobile assets.

Investments are still being allocated to infrastructure (95% of the total), mainly to projects in IT, 4G technology through 700 MHZ, transport network and FTTH expansion (which received approximately 9.6% of 1Q21 investments).

CHANGE IN WORKING CAPITAL

Change in working capital was negative by R$ 74 million, a 94.8% YoY improvement, mostly due to the reduction of the impact on the Suppliers account (the Suppliers account delta changed from R$ 1,305 million in 1Q20 to R$ 474 million in 1Q21). Additionally, in comparison with the 1Q20, in the present quarter, the line was positively impacted by the variation in Trade Accounts Receivable, Recoverable Taxes and Prepaid Expenses.

20

2021 First Quarter Results

Additionally, it is important to note that, regarding Fistel fees, in 1Q20, their payment was postponed (about R$ 789 million) – usually due in March – to August 31, 2020. In 3Q20, we paid nearly R$ 300 million related to said taxes, related to Condecine and CFRP, negatively impacting Change in Working Capital and Cash Flow for that quarter. In 1Q21, we paid nearly R$ 73 million related to CFRP. The remaining Fistel (TFF) amount, related to both years, is still suspended, without a defined payment date.

DEBT AND CASH

Gross Debt ended 1Q21 at R$ 10,235 million, up by R$ 79 million YoY. The current balance includes (i) leasing recognition in the total amount of R$ 8,180 million (related to the sale of towers, the LT Amazonas project and lease contracts with terms exceeding 12 months pursuant to IFRS 16); (ii) financing with banks summing up to R$ 2,545 million; and (iii) hedging derivatives5 position in the amount of R$ 651 million (reducing gross debt).

By the end of 1Q21, financings (after hedge) totaled R$ 2,056 million, being composed by contracts with foreign private banks and fully hedged in local currency. The average cost of debt excluding leases was 2.8% p.y. in the quarter, down when compared to 4.5% p.y. in 1Q20.

As mentioned during 2020, in April/20, the Company's Board of Directors approved the borrowing of R$ 1,000 million to enhance liquidity ahead of possible impacts that the COVID-19 pandemic could cause on the economy. Of that amount, R$ 574 million were borrowed from The Bank of Nova Scotia in the same month. During 2Q20, TIM assessed the best conditions for borrowing the remaining sum and in July the company contracted R$ 426 million from BNP Paribas. Also, in July, TIM fully paid its Debentures (~R$1,000 million) originally distributed in January 2019.

In March, TIM's Board of Directors approved the financing program for the acquisition of Oi's mobile assets. The approved financial strategy consists of contracting foreign loans in foreign or national currency - with exchange and interest rate coverage - in the amount of up to R$ 4 billion, for a period of up to 4 years. In April 2021, two contracts were signed with foreign banks, in the total amount of R$ 1.072 billion.

In April, the Company received authorization from the Ministry of Communications to issue up to R$ 5.75 billion in incentive debentures, the highest approval ever made by the Government within the scope of the program. The contribution may be used to finance TIM's infrastructure project, which covers the evolution of the fixed and mobile network, including 5G, and the virtualization of the telecommunication network, with the objective of increasing the quality and availability of the offered services.

21

2021 First Quarter Results

At the end of the quarter, Cash and Securities totaled R$ 4,319 million, an increase of R$ 2,723 million YoY.

The average cash yield was 2.4% p.y. in 1Q21, flat compared to the 1Q20, above the Selic rate performance.

In 1Q21, Net Debt totaled R$ 5,917 million, down by R$ 2,644 million when compared to the same period of the prior year, when net debt was R$ 8,561 million. This reduction is explained by the growth of Cash and Short-term Investments outpacing the rise of debt and leasing balance. Net Debt excluding leasing effects, Net Debt-AL, would reach -R$ 2,480 million, in other words, a “net cash” position with an improvement of R$ 2,873 million compared to the previous year.

Net Debt/EBITDA stood at 0.70x in the quarter. Excluding financial leases, Net Debt-AL/EBITDA-AL was -0.37x in 1Q21, down compared to 0.06x in 1Q20.

QUARTERLY EVENTS AND SUBSEQUENT EVENTS

CELEBRATION OF AGREEMENT WITH IHS OF SHAREHOLDING IN FIBERCO

On May 5th, 2021, TIM S.A., informed its shareholders and the market in general that, at a meeting of the Company's Board of Directors held today, an agreement ("Agreement") was approved between TIM S.A. and IHS Fiber Brasil - Cessao de Infraestruturas Ltda. ("IHS"), in order to acquire an equity stake in FiberCo Soluções de Infraestrutura Ltda. ("FiberCo"), a vehicle established by the Company for the segregation of network assets and the provision of infrastructure services.

IHS is a large and diversified telecommunications infrastructure provider focused on emerging markets and operating in 9 countries in Africa, Middle East and Latin America. IHS, besides owning more than 28 thousand towers, seeks the expansion of the value chain in infrastructure services.

In the Agreement, TIM will sell 51% of FiberCo's share capital in favor of IHS, and the remaining 49% will remain under the Company's control. The relationship between the partners will be governed by a shareholders' agreement to be entered into upon closing of the transaction.

FiberCo's initial asset base will consist of TIM's secondary network infrastructure contribution covering approximately 6.4 million households, of which 3.5 million are FTTH and 3.5 million FTTC. In addition, other assets, contracts and employees will be transferred to FiberCo, all exclusively related to its activities. These transfers will only take place after the Agreement is approved by the competent authorities.

In this context, the Enterprise Value of FiberCo was established at R$ 2.6 billion. The transaction includes a primary component (R$ 609,000,000.00) going to FiberCo’s cash and secondary component (R$ 1,027,590,000) to be paid to TIM.

FiberCo's mission is to deploy, operate and maintain last-mile infrastructure for broadband access to be offered in the wholesale market. Nevertheless, the terms of the agreement define TIM as anchor customer, having the prerogative of a 6 months exclusivity period after the entrance in new areas.

This transaction is expected to support the Company's plan to accelerate the provision of fiber connectivity services to B2C and B2B customers. Accordingly, FiberCo's business plan is to reach 8.9 million FTTH households within 4 years. FiberCo will also participate in other infrastructure projects, such as FTTSite, together with TIM.

This transaction has always been seen by the company from an industrial perspective, seeking the evolution and growth of its broadband business. However, the positive financial and economic impacts cannot be left aside. It is expected that the deal will enable the Company to deconsolidate a relevant part of its CAPEX, causing a positive effect on its cash flow. In parallel, TIM expects to use the proceeds of this transaction to help meeting its investment obligations, such as the acquisition of Oi Mobile's assets.

This transaction is subject to the fulfillment of certain preceding conditions, including, among others, the contribution of assets described above and the obtaining of authorizations from the competent authorities, such as the Agência Nacional de Telecomunicações - Anatel and the Conselho Administrativo de Defesa Econômica - CADE.

CREDIT AGREEMENTS WITH FOREIGN BANKS

In April 2021, the Company entered into two loan agreements with Banks BNP and Bank of Nova Scotia, in the total amount of R$ 1.1 billion. Those agreements are payable in three years. (Financial Statements, Note 20)

TAX CONTINGENCY

In March 2011, the Company received the tax assessment notice 10480.721765/2011-46, drawn up by the Brazilian Federal Revenue, in the amount of R$ 1,265 million, which addresses corporate income tax (IRPJ) and social contribution (CSL) related to: (i) goodwill; (ii) undue offset of tax losses and negative basis; (iii) allegedly improper use of the Sudene tax benefit; (iv) withholding income tax (IRRF) deductions; (v) deduction of estimates and (vi) fines.

The result of the judgment in the administrative trial court was the full maintenance of the assessment, but the voluntary appeal filed by the company was partially accepted. The company was notified of the judgment on April 28, 2021. As a result, the partial success of R$ 736 million (historical values) and R$ 1.4 billion (updated values) was confirmed.

Of the aforementioned total amount, R$ 43 million (historical values) and R$ 79 million (updated values) were already classified as remote risk and the remainder as possible risk. The full amount corresponding to the partial success will be definitively excluded from the tax contingency and the remaining amount will continue to be discussed in the course of the administrative proceeding, which will still be brought to the attention of the Upper Chamber of the Administrative Council of Tax Appeals (CARF).

The mobile market reported a growth of 6.2% YoY in 1Q21, reinforcing the positive evolution of the base, observed for the first time since 2015, in the last quarter. In the past 12 months, postpaid net additions reached 12.0 million users (68% were human postpaid lines). Prepaid reached 2.0 million new lines, posting net additions after 6 years.

TIM

TIM ended 1Q21 with a total of 51.2 million users, reporting a slight increase of 0.6% QoQ and a drop of 2.1% YoY. In line with the market movement, the new increase in the quarter reaffirms the discontinuation of reduction trend seeing since 2016.

|  | The postpaid base ended the 1Q21 with 22.2 million lines (+2.5% YoY), representing 43.0% of the total base (+2.0 p.p. YoY). In the period, the human lines mix remained flat, representing 82.3% over the total segment’s base. At the end of the quarter, human postpaid reached 18.3 million lines (+ 2.2% YoY), with net additions of 399 thousand lines in the last 12 months. 1Q21 was marked by new lockdown measures to combat the COVID-19 pandemic in relevant regions in the country. Despite the impact on commercial activity in the period, the segment maintained a lower level of monthly churn rate (2.7% in 1Q21), as recorded in the last quarters.

2021 First Quarter Results

The M2M base ended the quarter with 3.9 million users (+3.9% YoY). In the last 12 months, net additions accumulated 147 thousand lines. The acceleration of the segment still depends on an increase in demand from corporate customers, which is associated with a more intense level of economic activity.

In 1Q21, the prepaid base reached 29.5 million lines, down 5.3% YoY. The net additions of the segment accumulated a volume of disconnections lower than previous periods, 1.6 million in the last 12 months. Urban mobility restrictions directly impacted the sell-out dynamics over the period, however results from April-21 already show a more accelerated recovery in the segment's recharges performance.

The 4G base ended the period with 44.0 million users, accelerating once again the pace and returning to the double-digit growth level (+12.6% YoY). The 4G handsets mix in the total human lines base reached its highest historical level, 92% (+12 p.p. YoY).

FIXED SEGMENT:

TIM Live ended the 1Q21 with 662k connections, maintaining the accelerated growth pace (+13.3% YoY). In the last 12 months, net additions reached 78 thousand lines, where above 200 mbps speed plans were responsible for the expansion dynamics of the period. This was the first quarter of which the higher-value plans, with speed above 100 mbps, exceeded 50% of the total base. |  |

The network's rollout continued to accelerate, prioritizing the consolidation of already active clusters. As a result, the total of homes passed grew 39.9% YoY, with the total number of locations stable compared to the last quarter (27 cities and 7 administrative regions).

Quality and Network

QUALITY AND CUSTOMER EXPERIENCE

For yet another quarter, efforts to simplify self-service and boost digital sales channels have generated positive results. In 1Q21, pure postpaid digital sales were up by 35.4% YoY, while Consumer Control increase by 23.7% YoY. TIM Live’s digital sales gained relevance, posting a 30.4% YoY growth. Additionally, the digital recharges mix continued to increase (+15.8 p.p. compared to 1Q20).

27

2021 First Quarter Results

Accordingly, digital mechanisms for billing and payment kept their growth pace in the quarter. Invoices delivered through digital channels posted a 19.4% YoY growth, with a base penetration of 77.2% (+11.1 p.p. YoY). The number of customers digitally paying up their invoices also increased (+19.9% YoY) representing a penetration of 75.3% (+7.7 p.p. YoY). Another convenience offered to TIM’s customers is the possibility to recharge and/or check balances and usage limits, as well as the opportunity to receive their invoices through WhatsApp.

Another fundamental factor is the simplification of caring processes. Therefore, in 1Q21, Meu TIM app continued to be an important tool to achieve this goal, offering customers greater transparency and control to manage their plans. The 15.0% YoY growth in the app’s monthly average of unique users, once again demonstrates customer’s increasingly acceptance of this channel. Furthermore, the 29.7% YoY decline in human interactions also reinforces the channel’s importance, reducing dependency on call centers.

2021 First Quarter Results

Another ingenious initiative explored by the Company is the use of artificial intelligence at the customer service center. These innovations bring benefits to customers, by implementing tools that can automatically identify possible problems in the services provided to users, suggesting corrective measures, or solving them. TIM’s cognitive self-service provide voice responses, in natural language and in real time, to consumers’ doubts or demands about the benefits of each plan, invoice payment, in addition to other services such as hiring data service, unblock lines, question information and others. In 1Q21, we had 4 million self-services per month on average through the cognitive assistant. Since its implementation in 2020, over 34 million calls have come through the new cognitive IVR, of which 12 million only in 1Q21. We expect to reach 50 million cognitive services by the end of the year.

NETWORK DEVELOPMENT

A key pillar in TIM’s strategic plans, expansion and improvement of network infrastructure is related to the continuous improvement of our services. In difficult times, “more than never, we need to be connected”, and, therefore, TIM reinforced even further its commitment to ensuring the best network quality and user experience, meeting the needs of our customers and society’.

Therefore, in the quarter, Capex allocated to infrastructure projects (Network + IT) surpassed 95%, using analytical tools to ensure efficient allocation of resources. Some of the most important initiatives are:

| o | Expansion of the fiber optic network (backbone, backhaul and FTTH);

o Network sharing agreements;

o Frequency refarming;

o Carrier aggregation;

o Site densification.

Among the main actions and projects underway, which are focused on the modernization and enhancement of our infrastructure, we highlight:

| o | Commitment to expand of the 4G coverage to all Brazilian cities by 2023;

| o | Installation of multiple data centers to enhance experience, being 14 DCC (Data Center Core) and 19 DCE (Data Center Edge) - 33 in total at the end of 1Q21;

| o | Expansion of 4.5G coverage to 1,480 cities in 1Q21 and;

| o | Expansion of 700MHz frequency 4G use for 3,468 cities by the end of the year;

| o | Expansion of VoLTE, available in 4,086 cities;

| o | Extension of refarming of 2.1 GHz frequency in 4G, reaching 338 cities;

o Infrastructure virtualization project;

| o | Expansion of network capacity through the Massive MIMO solution;

| o | Mobile infrastructure sharing agreement with Vivo, geared towards efficiency in Capex and Opex allocation;

| o | Expansion to 122 sites installed in the Sky Coverage project (sustainable and extreme low-cost solution with social benefits to provide coverage in remote areas);

| o | Consolidation of NB-IoT network, present in more than 3,529 municipalities by the end the 1Q21, enabling the creation of IoT solutions in big cities as well as in distant municipalities.

2021 First Quarter Results

Once again, TIM ensures its leadership in 4G Coverage, surpassing 4k cities connected through this technology. Therefore, the Company continues its mission to offer the best 4G coverage to all Brazilian cities. In the quarter, 4G coverage has expanded to 4,121 cities, or 96% of urban population covered. The 21% YoY growth in this technology’s network elements in the period reinforces the Company’s commitment to the evolution of mobile network infrastructure’s quality and capacity. As a result, 4G data traffic reached 91%, up by 4 p.p. compared to the previous year.

The expansion of fixed broadband coverage evolved positively throughout the quarter, surpassing 3.5 million homes passed with FTTH while FTTC ended March at 3.5 million HPs. This totals 6.4 million homes passed in 29 cities and 7 administrative regions of the Federal District (FTTH +FTTC)6.

In transport infrastructure, TIM reached more than 109k km with fiber optic for backbone and backhaul, a 7.0% YoY increase, and in the FTTCity project reached to 1,021 cities. This evolution continues to support the increase in traffic in both Mobile and Fixed services.

Finally, with 1,709 active Biosites at the end of 1Q21, the development of Biosite installation projects is also aligned with the company's corporate social responsibility values. These structures provide a solution for the densification of the mobile access network (antennas/towers) with an extremely low visual and urban impact. Biosites also contribute to the harmonization with the environment and urban infrastructure – having a multifunctional capability of aggregating telecommunications transmission, lighting and security cameras –, besides being cheaper and faster to install.

1Q21 ESG HIGHLIGHTS

TIM has established a new and more ambitious plan named ESG Plan, for the 2021-23 three-year period.

2. Preparation basis and presentation of individual and consolidated quarterly information

The individual and consolidated quarterly information was prepared in accordance with accounting practices adopted in Brazil which include the resolutions issued by the CVM and the pronouncements, guidelines and interpretations issued by Comitê de Pronunciamentos Contábeis [Accounting pronouncements committee] (CPC) and the International Financial Reporting Standards (International Financial Reporting Standards ("IFRS"), issued by the International Accounting Standards Board (IASB) and show all relevant information specific to the quarterly information, and only this information, which is consistent with that used by management in its management. Additionally, the Company considered the guidelines provided for in Technical Guideline OCPC 07 - Evidencing upon Disclosure of General Purpose Financial-Accounting Reports in the preparation of its quarterly information. In this way, the relevant information specific to the quarterly information is being evidenced and correspond to those used by the management in its duties.

The main accounting policies applied in the preparation of this quarterly information are defined below and / or presented in their respective notes. Those policies were consistently applied in the years presented.

a. General criteria for preparation and disclosure

The individual and consolidated quarterly information was prepared considering the historical cost as value basis and financial assets and liabilities (including derivative financial instruments) measured at fair value.

Assets and liabilities are classified according to their degree of liquidity and collectability. They are reported as current when they are likely to be realized or settled over the next 12 months. Otherwise, they are recorded as non-current. The exception to this procedure involves deferred income tax and social contribution balances (assets and liabilities) and contingent liabilities that are fully classified as long-term.

The presentation of Statement of Value Added (Demonstração do Valor Adicionado – “DVA”) is required by the Brazilian Corporate Legislation and accounting practices adopted in Brazil applicable to listed companies. The DVA was prepared according to the criteria set forth in CPC Technical Pronouncement No. 09 - “Statement of Value Added”. IFRS does not require the presentation of this statement. As a consequence, according to the IFRS, this statement is presented as supplementary information, without affecting the quarterly information.

Interests paid are classified as financing cash flow in the statement of cash flows as it represents costs of obtaining financial resources.

b. Functional currency and presentation currency

The currency of presentation of the quarterly information is the Real (R$), which is also the Company´s functional currency.

NOTES TO THE QUARTERLY INFORMATION

March 31, 2021

(In thousands of Reais, except as otherwise stated)

Foreign currency transactions are recognized at the exchange rate on the date of the transaction. Monetary items in foreign currency are converted into reais at the exchange rate on the balance sheet date, informed by Banco Central do Brasil [Central Bank of Brazil]. Foreign exchange gains and losses linked to these items are recorded in the statement of income.

| c. | Segment information

Operating segments are components of the entity that carry out business activities from which revenues can be obtained and expenses incurred. Its operating results are regularly reviewed by the entity's main operations manager, who makes decisions on resource allocation and evaluates segment performance. For the segment to exist, individualized financial information is required.

The main operational decision maker in the Company, responsible for the allocation of resources and periodically evaluating performance, is the Executive Board, which, along with the Board of Directors, are responsible for making the strategic decisions of the company and its management.

The strategy is focused on optimizing results, and from the corporate reorganization mentioned in Note 1, all the operating activities of the group are concentrated exclusively in TIM S.A. Although there are diverse activities, decision makers understand that the company represents only one business segment and do not contemplate specific strategies focused only on one service line. All decisions regarding strategic, financial planning, purchases, investments and investment of resources are made on a consolidated basis. The aim is to maximize the consolidated result obtained by operating the SMP, STFC and SCM licenses.

| d. | Consolidation procedures

Subsidiaries are all the entities in which the Group retains control. The Group controls an entity when it is exposed to, or has a right over the variable returns arising from its involvement with the entity and has the ability to interfere in those returns due to its power over the entity. The subsidiaries are fully consolidated as of the date control is transferred to the Group. Consolidation is interrupted beginning as of the date in which the Group no longer holds control.

The purchase accounting method is used to record the acquisition of subsidiaries by the Group. The acquisition cost is measured as the fair value of the assets acquired, equity instruments (i.e..: shares) and liabilities incurred or assumed by the acquirer on the date of the change of control. Identifiable assets acquired, contingencies and liabilities assumed in a business combination are initially measured at fair value on the date of acquisition, regardless of the proportion of any minority interest. The portion exceeding the acquisition cost of the Group's interest in the acquired identifiable net assets, is recorded as goodwill. Should the acquisition cost be less than the fair value of the net assets of the acquired subsidiary, the difference is recognized directly in the statement of income as a revenue, once concepts and calculations applied are reviewed.

Intercompany transactions, as well as the balances and unrealized gains and losses in those transactions, are eliminated. The base date of the financial information used for consolidation purposes is the same for all the companies in the Group.

| e. | Approval of quarterly information

This quarterly information was approved by the Company's Board of Directors on May 5, 2021.

| f. | New standards, amendments and interpretations of standards

The following new standards/amendments were issued by the Accounting Pronouncement Committee (“CPC”) and International Accounting Standards Board (IASB), are effective for the year ended March 31, 2021.

| · | Changes to CPC 15 (R1): Definition of business

The amendments to CPC 15 (R1) clarify that, to be considered a business, an integrated set of activities and assets must include, at least, an inflow of funds and a substantive process that together contribute significantly to the capacity to generate the outflow of funds. Moreover, it clarified that a business can exist without including all the inflows of funds and processes necessary to create outflows of funds. These amendments had no impact on the Company’s individual and consolidated quarterly information but may impact future periods if the Group enters into any business combination.

| · | Changes in CPC 38, CPC 40 (R1) and CPC 48: Benchmark Interest Rate Reform

The amendments to Pronouncements CPC 38, CPC 48 and CPC 40 provide exemptions that apply to all hedge relationships directly affected by the benchmark interest rate reform. A hedge relationship is directly affected if the reform raises uncertainties about the period or the value of cash flows based on the benchmark interest rate of the hedged item or hedging instrument. These changes have no impact on the Company’s individual and consolidated quarterly information, as it does not have interest rate hedging relationships.

· Changes in CPC 26 (R1) and CPC 23: Definition of material

The amendments provide a new definition of material, stating that: “information is material if its omission, distortion or obfuscation can reasonably influence decisions that the main users of the general-purpose quarterly information make based on this quarterly information, which provide financial information on entity’s specific report”. The amendments clarify that the materiality will depend on the nature or magnitude of the information, individually or combined with other information, in the context of the financial statements. A distorted information is material if it could reasonably be expected to influence decisions made by primary users. These amendments had no impact on the individual and consolidated quarterly information, nor is it expected that there will be any future impact for the Company.

| · | Review in CPC 00 (R2): Conceptual Framework for Financial Reporting

The revised pronouncement provides some new concepts, provides updated definitions and recognition criteria for assets and liabilities and clarifies some important concepts. These changes did not affect the individual and consolidated quarterly information of the Company.

· Changes in CPC 06 (R2): Covid-19 related benefits granted to leaseholders in lease agreements.

The amendments provide for the granting of benefits to lessees upon adoption of the guidelines of CPC 06 (R2) on the modification of the lease agreement, when accounting for the related benefits as a direct consequence of the Covid-19 pandemic.

As a practical expedient, a lessee may choose not to assess whether a benefit related to Covid-19 granted by the lessor is a modification of the lease agreement. The lessee who makes this option must account for any change in the lease payment resulting from the benefit granted in the lease agreement related to Covid-19 in the same way that it would account for the change by adopting CPC 06 (R2) if the change was not a modification of the lease agreement.

The following new standards were issued by the Accounting Pronouncement Committee (“CPC”) and International Accounting Standards Board (IASB), but they are not effective for the year ended March 31, 2021.

In May 2017, the IASB issued IFRS 17 - Insurance Contracts (a standard not yet issued by CPC in Brazil, but which will be codified as CPC 50 - Insurance Contracts and will replace CPC 11 - Insurance Contracts), a new comprehensive accounting standard for insurance contracts that includes recognition and measurement, presentation and disclosure. As soon as it comes into force, IFRS 17 (CPC 50) will replace IFRS 4 - Insurance Contracts (CPC 11), issued in 2005. IFRS 17 applies to all types of insurance contracts (such as life, non-life, direct insurance and reinsurance), regardless of the type of entity that issues them, as well as certain guarantees and financial instruments with discretionary participation characteristics. Some scope exceptions apply. The overall objective of IFRS 17 is to provide an accounting model for insurance contracts that is more useful and consistent for insurers. In contrast to the requirements of IFRS 4, which are largely based on local accounting policies in force in previous periods, IFRS 17 provides for a comprehensive model for insurance contracts, covering all relevant accounting aspects. The focus of IFRS 17 is the general model, covering the following:

• A specific adaptation for contracts with direct participation characteristics (variable rate approach).

• A simplified approach (premium allocation approach), mainly for short-term contracts. IFRS 17 is effective for periods beginning on or after January 1, 2023, requiring the presentation of comparative amounts. Early adoption is allowed if the entity also adopts IFRS 9 and IFRS 15 on the same date or before the first-time adoption of IFRS 17.

This standard does not apply to the Company.

| · | Amendments to IAS 1: Classification of liabilities as current or non-current

In January 2020, the IASB issued amendments to paragraphs 69 to 76 of IAS 1, related to CPC 26, aiming to specify the requirements for classifying the liabilities as current or non-current. The amendments clarify the following:

• What a right to postpone settlement means;

• That the right to postpone settlement must exist on the base date of the report;

• That this classification is not affected by the likelihood that an entity will exercise its right to postpone settlement;

• That only if a derivative embedded in a convertible liability is itself an equity instrument would the terms of a liability not affect its classification. Amendments are valid for periods started on January 1, 2023 and must be applied on a retrospective basis.

The Company currently assesses the impact that the changes will have on current practice and whether existing loan agreements may require renegotiation.

COVID-19 impacts

Since March 2020 a pandemic was declared by the World Health Organization due to the outbreak of the new Coronavirus (COVID-19). The main impacts and first cases were recorded in Brazil and in the world also in the first quarter of 2020.

The outbreak of COVID-19 developed rapidly in 2020 and continues until 2021. The measures taken to contain the virus greatly affected economic activity, including some impacts on the operating results and cash flows of the Companies in Brazil. Throughout 2020, lockdowns were decreed in several states in Brazil, lasting from March to June 2020.

In 2021, the crisis worsened with an increase in the number of cases. Consequently, there was a need for new restrictive measures, including the closing of the trade, impacting the operation of stores. Said restrictions were implemented mainly in March in different cities in Brazil.

In 2020, the Company has a robust infrastructure and is part of an extremely important segment in this period of crisis, essential for the population, government and health system. After an internal analysis, there was no indication of impairment of assets or risks associated with the fulfilment of obligations, since the Company is not highly leveraged and still has credit lines available to be used in the event of a significant reduction in cash volume.

In 2021, we have not suffered any material impact on our operations so far. The Company continues to present positive results, and the main impact of the restriction measures was verified in the product sales line due to the closing of stores.

We continue assessing government responses, such as the progress of vaccination and economic performance, and we believe that a prolonged slowdown in local, regional or global economic conditions may affect the Company’s business in the future.

3. Estimates and areas where judgment is significant in the application of the company's accounting policies

Accounting estimates and judgments are continuously assessed. They are based on the Company's historical experience and on other factors, such as expectations of future events, considering the circumstances present in the base date of the quarterly information.

By definition, the resulting accounting estimates will rarely be the same as the actual results. The estimates and assumptions that present a significant risk, with the probability of causing a material adjustment to the carrying amounts of assets and liabilities for the fiscal period, are covered below.

(a) Impairment loss on non-financial assets

Impairment losses occur when book value of an asset or cash generating unit exceeds its recoverable value, which is the highest of fair value less selling costs and value in use. Calculation of fair value less selling costs is based on information available on similar assets’ selling transactions or market prices less additional costs to dispose of the asset. The calculation of value in use is based on the discounted cash flow model.

Any reorganization activities with which the Company is not committed to on the reporting date of the quarterly information or significant future investments that could improve the asset base of the cash generating unit under test are excluded for impairment testing purposes.

The main non-financial assets for which this assessment was made are goodwill recorded by the Company (Note 15) and its tangible assets.

(b) Income tax and social contribution (current and deferred)

Income tax and social contribution (current and deferred) are calculated according to interpretations of current legislation and CPC 32 / IAS 12. This process typically involves complex estimates to determine taxable income and temporary differences. In particular, the deferred assets on tax losses, negative basis of social contribution and temporary differences is recognized in proportion to the probability that future taxable income is available and can be used. The measurement of the recoverability of deferred income tax on tax losses, negative basis of social contribution and temporary differences takes the history of taxable income into account, as well as the estimate of future taxable income (Note 10).

(c) Provision for legal and administrative proceedings

The legal and administrative proceedings are analyzed by the Management along with its legal advisors (internal and external). The Company considers factors in its analysis such as hierarchy of laws, precedents available, recent court

judgments, their relevance in the legal system and payment history. These assessments involve Management’s judgment (note 24).

(d) Fair value of derivatives and other financial instruments

The financial instruments presented in the balance sheet at fair value are measured using valuation techniques that consider observable data or observable data derived from market (Note 36).

(e) Unbilled revenues

Since some cut dates for billing occur at intermediate dates within the months of the year, as the end of each month there are revenues earned by the Company, but not actually invoiced to its customers. These unbilled revenues are recorded based on estimate that takes into consideration historical consumption data, number of days elapsed since the last billing date, among others (Note 27).

(f) Leases

The Company has a significant number of the lease contracts in which it acts a lessee, and with the adoption of the accounting standard IFRS 16 / CPC 06 (R2) – Lease, on 01/01/2019, certain judgments were exercised by Company´s management in measuring lease liabilities and right-of-use assets, such as: (i) estimate of the lease term, considering non-cancellable period and the period covered by options to extend the contract term, when the exercise depends only from the Company, and this exercise is reasonably certain; (ii) using certain assumptions to calculate the discount rate.

The company is not able to readily determine the interest rate implicit on the lease and, therefore, considers its incremental rate on loans to measure lease liabilities. Incremental rate on the lessee’s loan is the interest rate that the lessee would have to pay when borrowing, for a similar term and with a similar guarantee, the resources necessary to obtain the asset with a value similar to the right of use asset in a similar economic environment. Thus, this assessment of lease, considering non-cancellable period and the period covered by options to extend the contract term. The Company estimates the incremental rate using observable data (such as market interest rates) when available and considers aspects that are specific to the Company (such as the cost of debt) in this estimate.

| 4. | Cash and cash equivalents

These are financial assets measured at amortized cost through the effective interest rate method.

| 6. | Trade accounts receivable

The balances as of March 31, 2021, presented below, represent the individual and consolidated amounts.

These are financial assets measured at amortized cost, and refer to accounts receivable from users of telecommunications services, from network use (interconnection) and from sales of handsets and accessories. Accounts receivable are recorded at the price charged at the time of the transaction. The balances of accounts receivable also include services provided and not billed (“unbilled”) up to the balance sheet date. Accounts receivable from clients are initially recognized at fair value and subsequently measured at amortized cost using the effective interest rate method less the provision for expected credit losses ("impairment").

The provision for expected credit losses was recognized as a reduction in accounts receivable based on the profile of the subscriber portfolio, the aging of overdue accounts receivable, the economic situation, the risks involved in each case and the collection curve, at an amount deemed sufficient by Management, as adjusted to reflect current and prospective information on macroeconomic factors that affect the customers’ ability to settle the receivables.

The fair value of trade accounts receivable is close to the book value recorded on March 31, 2021 and December 31, 2020.

The average rate considered in calculating the present value of accounts receivable recorded in the long term is 0.22% (0.22% on December 31, 2020).

(i) The amounts of income tax and social contribution are as substantially related to: (a) advances made over the period during which the use will take place at the closing of the current year and any balances in the next year; and (b) other income tax and social contribution credits from previous years whose current estimated period of use will be more than 12 months later.

(ii) The Recoverable PIS/COFINS amounts mainly refer to credits from a legal proceeding filed by TIM Celular S.A. (ultimately merged into TIM S.A.), as well as TIM S.A. itself, with a favorable final decision in Higher Courts which discussed the exclusion of the ICMS from the PIS and COFINS calculation bases. According to the Company’s internal assessment, we expect to use these credits by the end of the year 2022.

In March 2017, the Federal Supreme Court (“STF”) recognized the unconstitutionality of including ICMS amounts in the calculation base of PIS and COFINS contributions. TIM S.A. (previously named “Intelig Telecomunicações Ltda.”), as the surviving company from the merger of TIM Celular S.A. and other entities existing in the Group in the past, which had filed proceedings of the same nature, has been challenging this issue in court since 2006, with effects retroactive to five years, as permitted by the legislation. The total amount recorded in 2019 related to these credits was R$ 3,023 million, of which R$ 1,795 relates to principal and R$ 1,228 million was monetary restatement.

The amount recorded are updated monthly at the interest rate equivalent to the reference rate of the Special Settlement and Custody System (Selic), available on the website of the Brazilian Federal Revenue.

In 2020, TIM had utilized credits arising from the process of exclusion of ICMS from the calculation bases of PIS and COFINS, for payments of federal taxes, in the total amount of R$ 1.516 million. In the first quarter of 2021, total offsetting of R$ 275 million was made for said PIS and COFINS credits.

In March 2021, after partial use of TIM S.A credits, in the amount of R$ 1,853 million, it is still recorded in the amounts of R$ 1,270 million, of which R$ 825 million as principal and R$ 445 million as inflation adjustments.

| 10. | Deferred income tax and social contribution

The balances as of March 31, 2021, presented below, represent the individual and consolidated amounts.

Deferred income tax and social contribution are recognized on: (1) accumulated income tax carried forward losses and negative basis of social contribution, and (2) temporary differences arising from differences between the tax bases of assets and liabilities and their carrying values in the financial statements. Deferred income tax is determined using the tax rates (and tax laws) enacted, or substantially enacted, up to the balance sheet date. Subsequent changes in tax rates or tax legislation may modify the deferred tax credit and debit balances.

Deferred tax assets on income tax and social contribution are recognized only in the event of a profitable track record and/or when the annual forecasts prepared by the Company, examined by the Tax Council and Statutory Audit Committee and approved by other Management bodies, indicate the likelihood of the future realization of those tax credits.

The balances of deferred income tax assets and liabilities are presented at net value in balance sheet when there is the legal right and the intention of offsetting them upon calculation of current taxes, in general related to the same legal entity and the same tax authority. Thus, deferred tax assets and liabilities belonging to different entities are in general shown separately, not at their net amounts.

On March 31, 2021 and December 31, 2020, the prevailing tax rates were 25% for income tax and 9% for social contribution. In addition, there is no statute of limitation in regard to the income tax and social contribution carried forward losses, which it can be offset by up to 30% of the taxable profit reached at each fiscal year, according to the current tax legislation.

(2) as of the 1Q20, TIM S.A. excludes the portion of acceleration of depreciation of movable assets belonging to fixed assets from the calculation basis of the IRPJ and CSLL, due to their uninterrupted use in three operating shifts, supported by technical expert report, as provided for in Article 323 of the RIR/2018, or by the adequacy to the tax depreciation provided for in IN 1700/2017. Such tax adjustment generated a deferred liability of R$ 331.6 million until March 31, 2021 (R$ 266.5 million up to December 31, 2020) and applied as of January 1, 2020.

(3) In 2020, R$ 53 million of deferred tax liabilities were recorded on the gain arising from the mark-to-market of the share subscription option related to Banco C6 partnership (note 36).

Expectation of recovery of tax credits

The estimates of recoverability of tax credits were calculated taking into consideration financial and business assumptions available on March 31, 2021.

Based on these projections, the company has the following expectation of recovery of credits:

Deferred income tax and social contribution | Tax losses and negative basis |  | Temporary differences |  |
2021 | 157,080 |  | 475,448 |  |
2022 | 241,402 |  | (42,880) |  |
2023 | 50,289 |  | (77,202) |  |
2024 onwards | - |  | (318,557) |  |
Total | 448,771 |  | 36,809 |  | 485,580

The company based on a history of profitability and based on projections of future taxable results, constitutes deferred income tax credits and social contribution on all of its tax losses, negative social contribution basis and temporary differences.

The Company used credits from the negative basis of social contribution in the amount of R$ 26,357 during the quarter ended March 31, 2021 (R$ 325,583 on December 31, 2020, including tax losses).

The ownership interest in subsidiary is valued using the equity accounting method.

TIM’s Board of Directors, after analyzing the studies prepared and the non-binding proposals received, approved, in a meeting held on December 10, 2020, the incorporation of FiberCo Soluções de Infraestrutura Ltda. (“FiberCo”), a limited liability company, in preparation for a possible (or eventual) segregation of assets and provision of residential fiber optic infrastructure services. The Company was organized on December 16, 2020.

This process is one of the intermediate steps in the transformation of TIM in a provider of broadband services, and aims to create an open fiber optic infrastructure vehicle (“FiberCo”) with the acquisition of a strategic partner that will become a partner of FiberCo. FiberCo will operate in the wholesale market and can provide last-mile fiber connectivity and transportation services to market operators, with TIM as the client.

| 14. | Property, plant and equipment

The balances as of March 31, 2021, presented below, represent the individual and consolidated amounts.

Property, plant and equipment are stated at acquisition and/or construction cost, less accumulated depreciation and impairment losses (the latter only if applicable). Depreciation is calculated based on the straight-line method over terms that take into account the expected useful lives of the assets and their residual values. On March 31, 2021 and December 31, 2020, the Company has no indication of impairment in its property, plant and equipment.

The estimated costs of dismantling towers and equipment on rented properties are capitalized and depreciated over the estimated useful lives of these assets. The Company recognizes the present value of these costs in property, plant and equipment with a counter-entry to the liability “provision for future asset retirement”. Interest incurred on updating the provision is classified within financial expenses.

Gains and losses on disposal are determined by comparing the amounts of these disposals with the carrying values at the time of the transaction and are recognized in “other operating expenses (revenue), net” in the statement of income.

| 15. | Intangible assets

The balances as of March 31, 2021, presented below, represent the individual and consolidated amounts.

Intangible assets are measured at historical cost less accumulated amortization and impairment losses (if applicable) and reflect: (i) the purchase of authorizations and rights to use radio frequency bands, and (ii) software in use and/or development. Intangible assets also include: (i) infrastructure right-of-use of other companies, and (ii) goodwill on expectation of future profits in purchases of companies.

Amortization charges are calculated using the straight-line method over the estimated useful life of the assets contracted and over the terms of the authorizations. The useful life estimates of intangible assets are reviewed regularly.

Any financial charges on funds raised (that is, without a specific destination) and used to obtain a qualifying asset, meaning an asset that requires a significant time to be ready for use, are capitalized as a portion of the cost of the asset when it is likely to bring future economic benefits to the entity and such costs can be accurately measured. These costs are amortized throughout the estimated useful lives of the assets. Within this concept, we had the capitalization of charges for the acquisition of the 4G license and cleaning of the frequency of the 700 MHZ band acquired until

These companies were SCM providers in the main municipalities of the Greater São Paulo and Greater Rio de Janeiro areas, respectively.

TIM Fiber SP Ltda. and TIM Fiber RJ. S.A. were merged into TIM Celular S.A. on August 29, 2012.

TIM Celular S.A. recorded the goodwill allocation related to the purchase of the companies TIM Fiber SP and TIM Fiber RJ, at the end of the purchase price allocation process, in the amount of R$ 1,159,649.

On August 31, 2020, with the merger of TIM Participações S.A. by TIM S.A, the Company recorded the goodwill arising from the merger of the net assets of TIM Participações, which were originated in acquisition transactions as described below:

Goodwill acquisition of "Intelig" by TIM Participações – the goodwill arising from the acquisition of TIM S.A. (formerly ”Intelig") in December 2009 in the amount of R$ 210,015 is represented/based on the expectation of future profitability of the Company. Its recoverability is tested annually, through the impairment testing.

Goodwill from the acquisition of minority interests in TIM Sul and TIM Nordeste – TIM Participações S.A. (merged by TIM S.A. in August 2020) acquired in 2005, all the shares of the minority shareholders of TIM Sul and TIM Nordeste, in exchange for shares issued by TIM Participações, converting these companies into full subsidiaries. The goodwill resulting from this transaction amounted to R$ 157,556.

Impairment test

As required by the accounting standard, the Company tests goodwill on business combinations involving TIM Group companies annually for impairment, and the methods and assumptions used by Management in the impairment testing of goodwill mentioned above are summarized below:

The management of the Company understands that the smallest unit generating cash for impairment testing of goodwill in the acquisition of the companies previously described covers the business at the consolidated level, therefore it covers the consolidated group. This methodology is aligned with the company's strategic direction. It is important to note that the results of

65

TIM S.A. and TIM S.A. and SUBSIDIARY

NOTES TO THE QUARTERLY INFORMATION

March 31, 2021

(In thousands of Reais, except as otherwise stated)

the group are essentially represented by TIM S.A. Thus, the results of TIM S.A. are the main cash generator of the TIM Group, since the only operating company operating in Brazil is TIM S.A., and thus the Company represents a single cash-generating unit for the purpose of impairment test of assets with indefinite useful lives, pursuant to IAS 36 / CPC 01.

On December 31, 2020, the impairment test was performed by comparing the book value with the fair value minus the disposal costs of the asset, as foreseen in IAS 36 / CPC 01.

For the calculation of fair value, the level of hierarchy within which the measurement of the fair value of the asset (cash generating unit) is classified was considered. For the company, as there is only one CGU this was classified in its entirety as Level 1, for the disposal costs we consider that it is irrelevant considering the variation between the fair value level 1 and the carrying amount of the cash generating unit.

The fair value of Level 1 financial instruments comprises the instruments traded in active markets and based on quoted market prices on the balance sheet date. A market is considered active when the quoted prices are readily and regularly available from an Exchange, distributor, broker, industry group, pricing service or regulatory agency, and these prices represent actual market transactions which occur regularly on a purely commercial basis.

Its securities are traded on BOVESPA with code (TIMS3) and have a regular trading volume that allows the measurement (Level 1) as the product between the quoted price for the individual asset or liability and the amount held by the entity.

The measurement was made based on the value of the share at the balance sheet closing date and sensitivity tests were also performed and in none of the scenarios was identified any indication of impairment, being the fair value determined higher than the carrying amount. Therefore, being the fair value higher than the carrying amount, it is not necessary to calculate the value in use. The effects of TIM Participações holding (incorporated by TIM S.A) on the value of the carrying amount are irrelevant and also its effects on the result of the Consolidated Group. Therefore, the calculations carried out at the consolidated level essentially contemplate the results and accounting balances of TIM S.A., so the management of the Company concludes that the use of the fair value less of cost of sales methodology is adequate to conclude that there is no provision for impairment since the fair value less the cost of sales is higher than the total book value of the cash generating unit.

On March 31, 2021, the Company carried out the analysis of all tangible and intangible assets and did not identify any impairment indicators and, therefore, there was no need to review the impairment test in the period.

(e) Right to use infrastructure - Lt Amazonas

The company has signed infrastructure rights agreements with companies that operate electricity transmission lines in the Northern Region of Brazil. These contracts fall within the scope of IFRIC 4 / ICPC 3 as financial commercial leases.

Additionally, the Company has signed network infrastructure sharing agreements with Telefónica Brasil S.A., also in the North Region. In these, the two operators optimize resources and reduce their respective operating costs (note 16).

(f) Authorizations

In this item are recorded the values related to the acquisition of Lot 2 in the auction of the 700 MHz band in the amount of R$ 1,739 million, in addition to the costs related to the cleaning of the frequency of the 700 MHZ band acquired, which totaled R$1,199 million, in nominal values. As it is a long-term obligation, the amount payable of R$ 1,199 million was reduced by R$ 47 million by applying the concept of adjustment to present value (“AVP”).

The aforementioned license falls under the concept of qualifying asset. Consequently, the financial charges on resources raised without a specific destination, used for the purpose of obtaining a qualifying asset, were capitalized between the years 2014 to 2019.

| 16. | Leases

The balances as of March 31, 2021, presented below, represent the individual and consolidated amounts.

Leases that the Company, as a lessee, holds substantially all the risks and rewards of ownership are classified as finance leases. They are capitalized at the lease's commencement at the lower of the fair value of the leased asset and the present value of payments provided for in contract, and lease liability as a counterparty. Interest related to the leases is taken to income as financial costs over the term of the contract.

Leases in which the Company, as a lessor, transfers substantially all the risks and rewards of ownership to the other party (lessee) are classified as finance leases. These lease values are transferred from the intangible assets of the Company and are recognized as a lease receivable at the lower of the fair value of the leased item and/or the present value of the receipts provided for in the agreement. Interest related to the lease is taken to income as financial revenue over the contractual term.

Asset leases are financial assets or liabilities classified and/or measured at amortized cost.

The total amount charged against the TIM Group in relation to the contributions to FUST and FUNTTEL with a possible risk rating is R$ 3,022,754 (R$ 3,014,976 as of December 31, 2020). The main discussion involves the collection of the contribution to FUST and FUNTTEL (Fund for the technological development of Telecommunications) from the issuance by ANATEL of Sum no. 07/2005, aiming, among others, and mainly, the collection of the contribution to FUST and FUNTTEL on interconnection revenues earned by mobile telecommunications service providers, from the validity of Law 9998/2000.

e.4. Regulatory

ANATEL filed administrative proceedings against the Company for: (i) non-compliance with certain quality indicators; (ii) non-compliance with other obligations derived from the terms of authorization and; (iii) non-compliance with the SMP and STFC regulations, among others.

On March 31, 2021, the value indicated for the PADOs (procedure for determining non-compliance with obligations), considering the inflation adjustment, classified with possible risk was R$ 116,982 (R$ 119,076 on December 31, 2020). The variation was mainly due to the processing of the PADOs included in the Conduct Adjustment Term “TAC” in negotiations with ANATEL, where such processes were extinguished in the administrative spheres.

During the first quarter of 2021, the Company carried out all the activities planned for the strict compliance with the Conduct Adjustment Instrument (TAC) 001/2020 entered into with Anatel, including the activities of support to the Agency’s inspection for the commitments due on December 31, 2020. Until the end of the quarter, no schedule delays were identified and, throughout the four years of execution of the TAC, the Company will continue fully implementing the internal monitoring mechanisms through the quarterly report on the evolution of the schedules by the Governance Office in Management and Board of Directors.

By obtaining the extension of the term of the authorizations to use the radio frequencies associated with the SMP, TIM S.A. becomes liable for the contractual burden on the net revenue arising from the service plans marketed under each authorization. However, since 2011 ANATEL began to include in the basis of calculation of said burden also the revenues obtained with interconnection, and from 2012, the revenues obtained with Value-Added Services. In the company's opinion, the inclusion of such revenues is improper because it is not expressly provided for in the terms of original authorizations, so the collections received are discussed in the administrative and/or judicial sphere.

The 2011-2013 and 2014-2016 plans addresses the granting of stock options, while the 2018-2020 plan provides for the granting of shares (performance shares and restricted shares).

The exercise of the options of the 2011-2013 Plan is conditioned on the achievement of specific performance targets that could prevent the exercise of options, while when in the exercise of the options of the 2014-2016 Plan, the achievement of goals may affect only the acquisition price of the shares. The strike price is calculated by applying a plus or minus adjustment to the Base price of the share as a result of shareholder performance, taking into account the criteria provided for in each plan.

The 2018-2020 Plan proposes to grant participants shares issued by the Company, subject to the participant’s permanence in the Company (achievement of specific goals). The number of shares may vary, for more or for less, as a result of the performance and possibly of the dividend award, considering the criteria provided for in each Grant.

The term of validity of the options of the 2011-2013 and 2014-2016 plans is 6 years and TIM S.A. has no legal or non-formalized obligation to repurchase or settle the options in cash. For the 2018-2020 plan, the term of validity has the same periodicity of 3 years related to its deficiency (Vesting). In turn, the 2018-2020 plan, in addition to considering the transfer of shares, also provides for the possibility of making payment to participants of the equivalent amount in cash.

The total amount of the expense was calculated considering the fair value of the options and the value of the shares and is recognized in the results over the vesting period.

Revenues are recognized monthly, through billing, and revenues to be billed between the billing date and the end of the month (unbilled) are identified, processed, and recognized in the month in which the service was provided. These non-billed revenues are recorded on an estimated basis, which takes into account consumption data, number of days elapsed since the last billing date.

Interconnection traffic and roaming revenue are recorded separately, without offsetting the amounts owed to other telecom operators (the latter are accounted for as operating costs).

The minutes not used by customers and/or reload credits in the possession of commercial partners regarding the prepaid service system are recorded as deferred revenue and allocated to income when these services are actually used by customers.

The service revenue item also includes revenue from financial partnership agreements and, as provided for in the agreement, the amounts of revenues recognized in the first quarter of 2021 since TIM customers opened accounts with our financial partner C6, which was approximately R$ 11 million (note 36).

Revenues from sales of goods

Revenues from sales of goods (telephones, mini-modems, tablets and other equipment) are recognized when the performance obligations associated with the contract are transferred to the buyer. Revenues from sales of devices to trading partners are accounted for at the time of their physical delivery to the partner, net of discounts, and not at the time of sale to the end customer, since the Company has no control over the good sold.

Contract Identification

The Company monitors commercial contracts in order to identify the main contractual clauses and other elements present in the contracts that could be relevant in the application of the accounting rule IFRS 15 / CPC47 – Revenue from Contracts with Customers.

Identification of the performance obligation

Based on the review of its contracts, the Company verified the existence of two performance obligations:

(i) sale of equipment; and

(ii) provision of mobile, fixed and internet telephony services.

Thus, the Company started to recognize revenues when (or as) the Company meets the performance obligation by transferring the asset or service promised to the client; and the asset is considered transferred when (or as) the client obtains control of that asset.

Determining and Allocating the Transaction Price to the Performance Obligation

The Company understands that its commercial packages that combine services and sale of cellular handsets with discounts. In accordance with IFRS 15 / CPC 47, the Company is required to perform the discount allocation and recognize revenues related to each performance obligation based on their standalone selling prices.

At each balance sheet date such liabilities are measured at their fair value. Interest, monetary correction, foreign exchange variation and changes arising from the fair value measurement, where applicable, shall be recognized in the result when incurred, under the line of financial revenues or expenses.

Initially, derivatives are recognized at fair value on the date a derivative contract is concluded and are subsequently remeasured at fair value. The company does not apply “hedge accounting”.

The company carries out transactions with derivative financial instruments, without speculative purposes, only with the aim of i) reducing risks related to exchange rate variation and ii) managing interest rate exposure. The Company's derivative financial instruments are specifically represented by swap and options contracts.

TIM S.A. and TIM S.A. and SUBSIDIARY

NOTES TO THE QUARTERLY INFORMATION

March 31, 2021

(In thousands of Reais, except as otherwise stated)

The company's financial instruments are being presented in compliance with IFRS 9 / CPC 48.

The main risk factors that the company is exposed to are as follows:

(i) Foreign exchange variation risks

The risks of foreign exchange variations relate to the possibility of the Company computing i) losses derived from fluctuations in exchange rates by increasing the balances of debt with loans and financing obtained in the market and the corresponding financial expenses or ii) increase in cost in commercial contracts that have some type of link to foreign exchange change. In order for these types of risks to be mitigated, the company performs: swap contracts with financial institutions with the aim of cancelling the impacts arising from the fluctuation of exchange rates on the financial result and commercial contracts with foreign exchange band clauses with the aim of partially mitigating foreign exchange risks or derivative financial instruments to reduce the risks of foreign exchange exposure in commercial contracts.

On March 31, 2021, the company's loans and financings indexed to the variation of foreign currencies are fully protected, both in terms and in value, by swap contracts. Gains or losses on these swap contracts are recorded in the company's earnings.

In addition to the risks mentioned above, there are no other financial assets and liabilities in significant amounts that are indexed to foreign currencies.

(ii) Interest rate risks

Interest rate risks relate to:

The possibility of variations in the fair value of the loans obtained by the company indexed to TJLP, IPCA and/or TLP, when such rates do not correspond proportionally to the rates relating to Interbank Certificates of Deposit (CDI). On March 31, 2021, the Company had no swap operation pegged to long-term interest rate (TJLP), IPCA and/or TLP.

The possibility of an unfavorable movement in interest rates would cause an increase in the financial expenses of the Company, as a result of the share of the debt and the passive positions that the Company has in swap contracts linked to floating interest rates (percentage of the CDI). However, on March 31, 2021, the Company maintains its financial resources applied to Interbank Certificates of Deposit (CDI), which substantially reduces this risk.

(iii) Credit risk inherent in the provision of services

The risk is related to the possibility of the company computing losses derived from the inability of the subscribers to honor the payments of the invoiced amounts. To minimize this risk, the company preventively performs credit analysis of all orders imputed by the sales areas and monitors the accounts receivable of subscribers, blocking the ability to use services, among other actions, if customers do not pay their debts. There are no customers who have contributed more than 10% of net accounts receivable on March 31, 2021 and December 31, 2020 or revenues from services rendered during the period ended March 31, 2021 and 2020.

(iv) Credit risk inherent in the sale of telephone sets and prepaid telephone cards

102

TIM S.A. and TIM S.A. and SUBSIDIARY

NOTES TO THE QUARTERLY INFORMATION

March 31, 2021

(In thousands of Reais, except as otherwise stated)

The group's policy for the sale of telephone devices and the distribution of prepaid telephone cards is directly related to the credit risk levels accepted during the normal course of business. The selection of partners, the diversification of the portfolio of accounts receivable, the monitoring of loan conditions, the positions and limits of orders established for traders, the formation of collateral are procedures adopted by the company to minimize possible collection problems with its trading partners. There are no customers who contributed more than 10% of merchandise sales revenue during the period ended March 31, 2021 and 2020. There are no customers who contributed more than 10% of the net receivables from the sale of goods as of March 31, 2021 and December 31, 2020.

(v) Liquidity risk

- Liquidity risk arises from the need for cash before the obligations assumed. The company structures the maturities of its non-derivative financial instruments and their respective derivative financial instruments so as not to affect liquidity.

- The management of liquidity and cash flow of the Company are performed on a daily basis to ensure that cash operating generation and previous fund raising, as necessary, are sufficient to maintain the schedule of operating and financial commitments.

- All financial investments of the Company have daily liquidity and the Management may, even in specific cases: i) revise the dividend payment policy; ii) issue new shares; and/or, iii) sell assets to increase liquidity.

(vi) Financial credit risk

The cash flow forecast is carried out and aggregated by the Finance and Treasury Department of the company. This department monitors ongoing forecasts of liquidity requirements to ensure that the company has sufficient cash to meet operational needs. This forecast takes into account investment plans, debt financing, compliance with contractual clauses, compliance with internal goals and, if applicable, external regulatory or legal requirements.

The risk is related to the possibility of the company computing losses derived from the difficulty of redemption of short-term financial investments and swap contracts, due to possible insolvency of counterparties. The company minimizes the risk associated with these financial instruments by maintaining operations only with financial institutions of recognized market strength, in addition to following a policy that establishes maximum levels of risk concentration per financial institution.

Other derivatives are instruments of share subscription options represent the option of the Company to subscribe 1.4% of the shares of C6 capital, where the Group/Company paid a share subscription premium in the amount of R$ 6.2 million. As required by IRFS 9, the financial instrument must be valued at its fair value that on March 31, 2021 and on December 31, 2020 corresponds to R$ 161 million. The impact of the mark-to-market of the stock conversion option calculated, of R$ 155 million, represents the difference in the fair value of the option less the amount paid for the share subscription premium. This financial instrument was measured at fair value and will be subsequently measured in the company’s results for the year. In March 2021, the Company assessed the remeasurement of the instrument’s fair value and did not identify the need for adjustment in the period.

Non-derivative financial liabilities are substantially composed of accounts payable to suppliers, dividends payable and other obligations, the maturity of which will occur in the next 12 months, except for loans and financing and lease, the nominal flows of payments of which are disclosed in notes 20 and 16.

The fair value of financial instruments traded on active markets is based on market prices quoted on the balance sheet date. A market is seen as active if quoted prices are ready and regularly available from a Stock Exchange, distributor, broker, industry group, pricing service, or regulatory agency, and those prices represent real market transactions and that occur regularly on purely commercial basis. These instruments are included in Level 1. The instruments included in Level 1 mainly comprise the equity investments of bank certificates of deposit (CDB) and committed classified as securities for trading.

The fair value of financial instruments that are not traded on active markets (e.g. over-the-counter derivatives) is determined using valuation techniques. These valuation techniques maximize the use of data adopted by the market where it is available and rely as little as possible on entity-specific estimates. If all relevant information required for the fair value of an instrument is adopted by the market, the instrument is included in Level 2.

If one or more relevant information is not based on data adopted by the market, the instrument shall be included in Level 3.

Specific valuation techniques used to value financial instruments include:

| · | Quoted market prices or quotes of financial institutions or brokers for similar instruments.

| · | The fair value of interest rate swaps is calculated by the present value of estimated future cash flows based on the yield curves adopted by the market.

| · | Other techniques, such as analysis of discounted cash flows, available data of the last relevant transaction and analysis of results based on multiples of similar companies, are used to determine the fair value of the remaining financial instruments.

Regular purchases and sales of financial assets are recognized on the trading date - the date on which the Company undertakes to buy or sell the asset. Investments are initially recognized at fair value. After initial recognition, changes in fair value are recorded in the profit and loss for the year, in the financial revenues and expenses’ group.

Financial risk hedge policy adopted by the Company

The company's policy establishes that mechanisms must be adopted to protect against financial risks arising from the contracting of financing, in foreign currency, in order to manage the exposure of risks associated with foreign exchange variation.

The contracting of derivative financial instruments against foreign exchange exposure shall occur simultaneously with the contracting of the debt that gave rise to such exposure. The level of coverage to be contracted for such foreign exchange exposures shall be 100% of the risk, both in terms and in value.

On March 31, 2021, there are no margins or guarantees applied to transactions with derivative financial instruments of the Company.

The selection criteria of financial institutions follow parameters that take into account the rating provided by renowned risk analysis agencies, net worth and levels of concentration of operations and resources.

As the Company has derivative financial instruments for the purposes of protection of its respective financial liabilities, the changes in the scenarios are accompanied by the respective object of protection, thus showing that the effects related to the exposure generated in the swaps will have their counterpart reflected in the debt. For these transactions, the Company discloses the fair value of the object (debt) and the protective derivative financial instrument on separate lines, as demonstrated above in the sensitivity analysis demonstration table, in order to report the company's net exposure in each of the three scenarios mentioned.

It is noteworthy that the operations with derivative financial instruments contracted by the company have as sole objective the patrimonial protection. In this way, an improvement or worsening in their respective market values will be equivalent to an inverse movement in the corresponding portions of the value of the financial debt contracted, object of the derivative financial instruments of the company.

The sensitivity analyses for derivative financial instruments in force on March 31, 2020 were carried out considering, basically, the assumptions related to changes in market interest rates and the change in the US dollar used in swap contracts. The use of these assumptions in the analysis is due exclusively to the characteristics of derivative financial instruments, which have exposure only to changes in interest and exchange rates.

In April 2021, the Company entered into two loan agreements with Banks BNP and Bank of Nova Scotia, in the total amount of R$1.1 billion. Those agreements are payable in three years.

Tax contingency

In March 2011, the Company received the tax assessment notice 10480.721765/2011-46, drawn up by the Brazilian Federal Revenue, in the amount of R$ 1,265 million, which addresses corporate income tax (IRPJ) and social contribution (CSL) related to: (i) goodwill; (ii) undue offset of tax losses and negative basis; (iii) allegedly improper use of the Sudene tax benefit; (iv) withholding income tax (IRRF) deductions; (v) deduction of estimates and (vi) fines.

The result of the judgment in the administrative trial court was the full maintenance of the assessment, but the voluntary appeal filed by the company was partially accepted. The company was notified of the judgment on April 28, 2021. As a result, the partial success of R$ 736 million (historical values) and R$ 1.4 billion (updated values) was confirmed.

Of the aforementioned total amount, R$ 43 million (historical values) and R$ 79 million (updated values) were already classified as remote risk and the remainder as possible risk. The full amount corresponding to the partial success will be definitively excluded from the tax contingency and the remaining amount will continue to be discussed in the course of the administrative proceeding, which will still be brought to the attention of the Upper Chamber of the Administrative Council of Tax Appeals (CARF).

Celebration of Agreement with IHS of shareholding in FiberCO

On May 5th, 2021, TIM S.A., informed its shareholders and the market in general that, at a meeting of the Company's Board of Directors held today, an agreement ("Agreement") was approved between TIM S.A. and IHS Fiber Brasil - Cessao de Infraestruturas Ltda. ("IHS"), in order to acquire an equity stake in FiberCo Soluções de Infraestrutura Ltda. ("FiberCo"), a vehicle established by the Company for the segregation of network assets and the provision of infrastructure services.

IHS is a large and diversified telecommunications infrastructure provider focused on emerging markets and operating in 9 countries in Africa, Middle East and Latin America. IHS, besides owning more than 28 thousand towers, seeks the expansion of the value chain in infrastructure services.

In the Agreement, TIM will sell 51% of FiberCo's share capital in favor of IHS, and the remaining 49% will remain under the Company's control. The relationship between the partners will be governed by a shareholders' agreement to be entered into upon closing of the transaction.

FiberCo's initial asset base will consist of TIM's secondary network infrastructure contribution covering approximately 6.4 million households, of which 3.5 million are FTTH and 3.5 million FTTC. In addition, other assets, contracts and employees will be transferred to FiberCo, all exclusively related to its activities. These transfers will only take place after the Agreement is approved by the competent authorities.

In this context, the Enterprise Value of FiberCo was established at R$ 2.6 billion. The transaction includes a primary component (R$ 609,000,000.00) going to FiberCo’s cash and secondary component (R$ 1,027,590,000) to be paid to TIM.

FiberCo's mission is to deploy, operate and maintain last-mile infrastructure for broadband access to be offered in the wholesale market. Nevertheless, the terms of the agreement define TIM as anchor customer, having the prerogative of a 6 (six) months exclusivity period after the entrance in new areas.

This transaction is expected to support the Company's plan to accelerate the provision of fiber connectivity services to B2C and B2B customers. Accordingly, FiberCo's business plan is to reach 8.9 million FTTH households within 4 years. FiberCo will also participate in other infrastructure projects, such as FTTSite, together with TIM.

This transaction has always been seen by the company from an industrial perspective, seeking the evolution and growth of its broadband business. However, the positive financial and economic impacts cannot be left aside. It is expected that the deal will enable the Company to deconsolidate a relevant part of its CAPEX, causing a positive effect on its cash flow. In parallel, TIM expects to use the proceeds of this transaction to help meeting its investment obligations, such as the acquisition of Oi Mobile's assets.

This transaction is subject to the fulfillment of certain preceding conditions, including, among others, the contribution of assets described above and the obtaining of authorizations from the competent authorities, such as the Agência Nacional de Telecomunicações - ANATEL and the Conselho Administrativo de Defesa Econômica - CADE.
