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. (the “Company”) for the quarter ended March 31, 2023, comprising the balance sheet as of March 31, 2023 and the statements of income, of comprehensive income, of changes in shareholders’ equity and of cash flows for the three-month period then ended, including the explanatory notes.

Management is responsible for the preparation of the individual and consolidated interim financial information in accordance with NBC TG 21 – Interim Financial reporting, 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.

Independent auditor’s report on the quarterly information

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 abovementioned quarterly information includes the individual and consolidated statement of value added (SVA) for three-month period ended March 31, 2023, prepared under Company’s Management responsibility and presented as supplementary information by IAS 34. These statements have been subject to review procedures performed together with the review of the quarterly information with the objective to conclude whether they are reconciled to the interim financial information and the accounting records, as applicable, and if its format and content are in accordance with the criteria set forth by NBC TG 09 – Statement of Value Added. Based on our review, nothing has come to our attention that causes us to believe that they were not prepared, in all material respects, consistently with the overall individual and consolidated interim financial information.

On April 20, 2022, TIM S.A., together with the Buyer companies, after complying with the previous conditions established by CADE and ANATEL, concluded the acquisition transaction, with TIM, which currently holds 100% of the share capital of Cozani, a company that corresponds to the part of the unit of assets, rights and obligations of Oi Móvel acquired by Company.

The Company has been complying with all the measures provided for in Anatel’s conditions and in the Concentration Control Agreement (“ACC”) entered into with CADE, mainly, among others:

On April 19, 2022, TIM made the Product Reference Offer available in the wholesale ROAMING market (“ORPA – National Roaming”), which was approved by Anatel on September 21, 2022. On the same date, it made the Reference Offer for Mobile Virtual Network Operators (“Reference Offer – MVNO”) available, which was approved by Anatel on September 26, 2022.

On July 4, 2022, TIM independently made public offers for the disposal of up to 50% of Radio Base Stations (“RBDs”) acquired from Oi Móvel (“Public Offerings of RBSs”). Considering that the Offer should be available for up to six (6) months from its publication for potential interested parties to manifest themselves, and should be extended for an additional two (2) months in case of no interested parties, the term in question for the obligation of its availability ended on February 23, 2023, without any acquisition by interested parties. Thus, the Offer was withdrawn from TIM’s website.

On July 5, 2022, TIM and Oi Móvel signed a Letter of Intent to guarantee the maintenance and continuity of the mobile services provided at the Comandante Ferraz Antarctic Station (EACF) until the end of the term on February 21, 2024 of Cooperation Agreement 12.000/2019-001/00, signed on February 21, 2019 by the Federal Government, through the Navy Command, and by Telemar Norte Leste and Oi Móvel. The signing arrangements for the First Amendment to said Cooperation Agreement, which formalizes the result of said negotiations, were concluded on December 9, 2022.

On August 15, 2022, TIM signed the Radiofrequency Availability Agreement with Oi to allow Oi to meet the targets for the implementation of fixed wireless access systems provided for in the General Plan of Universalization Targets for the Universalization of the Switched Fixed Telephone Service Provided in the Public Regime (PGMU-IV), approved by Decree 9619/2018. The purpose of such agreement, as provided for by ANATEL, is to enable the continuity of the targets already achieved, and the fulfillment of non-complied and enforceable targets. The agreement is effective until the end of Oi’s STFC concession on December 31, 2025, and is registered as the service becomes available.

On October 20, 2022, TIM published Offers aimed at enabling the execution of an Industrial Network Exploration Agreement (“Offer – Industrial Network Exploration”) and Temporary and Onerous Assignment of Rights of Use of Radiofrequency (“Offer – Radiofrequency”), under the terms defined by the ACC (Agreement on Control of Concentrations) signed with CADE. The offers in question were published on TIM’s website and presented to CADE on the same date, within the period established by the ACC (up to 6 months

from Closing), and should be available for 36 months. No contracts have been entered into so far.

On December 20, 2022, TIM published offers intended to enable the signing of a Contract for the Temporary and Onerous Assignment of Rights of Use of the 900 MHz Radiofrequency, having as its object the radio frequencies acquired from Oi Móvel in said frequency band (“Offer – 900 MHz Radiofrequency”) under the terms set forth by the ACC entered into with CADE. The ACC is waiting a certificate of compliance from CADE. The offers in question were published on TIM’s website and presented to CADE on the same date, within the period established by the ACC (up to 8 months from Closing), and should be available for 36 months. No contracts have been entered into so far.

The acquisition price of 100% of Cozani’s shares, after all the adjustments provided for in the Share Purchase Agreement, was R$ 7,014.6 million.

Adjusted Closing Price:

(i)

R$ 634.3 million reais were withheld by TIM, as provided for in the purchase agreement, mainly to meet the possible need for additional price adjustments to be made, which could be identified in the 120 days after the acquisition date. According to the material fact disclosed on September 19, 2022, as a result of the differences found in the assumptions for calculating the topics: (i) Working Capital and Net Debt, (ii) Capex and (iii) Net Additions, the amount of R$ 634.3 million, (R$ 712 million updated on March 31, 2023) remained fully retained by the Company until the date of October 4, 2022, that the preliminary decision was handed down by the 7^th Business Court of the Judicial District of Rio de Janeiro determining the deposit in court by the Buyers, with TIM being responsible for depositing the updated amount up to that date of R$ 670 million in an account linked to the court-ordered reorganization process of Oi Móvel S.A. Said deposit will remain in an account linked to the Court pending the installation of the Court of Arbitration. For further details, see Note 12;

(ii)

The amount of R$ 2,057.4 million was transferred directly to BNDES - National Bank for Social and Economic Development, as per the contractual provision; and

(iii)

The balance of R$ 4,285.9 million was transferred directly to the Assignor on the acquisition date.

(iv)

The amount of R$ 1.8 million related to termination amounts related to the Seller’s personnel, agreed as part of the amount paid for the acquisition by the Buyers.

In addition to the above amounts, the Seller may be entitled to receive up to an additional R$ 230 million from TIM, conditioned to the

achievement, up to March 31, 2023, of certain targets related to the radio frequencies and customer base involved in the Transaction. Of this amount, R$ 120 million have already been paid due to the fulfillment of part of the established targets. Of the remaining amount not yet paid (R$ 110 million), the Company understands that might disburse the amount of R$ 77 million recognized as contingent consideration on the date of disclosure of this financial information.

On March 31, 2023, the total consideration recorded for the acquisition of Cozani was R$ 7,211.6 million.

Identifiable assets acquired and liabilities assumed

On December 31, 2022, the fair value of the identifiable assets acquired and liabilities assumed from Cozani on the date of acquisition by TIM S.A. is finalized, according to the purchase price allocation report (“Price purchase allocation”).

(ii)

The evaluation of the customer portfolio was conducted using the profitability approach, using the MPEEM (Multi-period excess earning method) method based on a calculation of cash flows from future economic benefits attributable to the customer base. The average useful life is 7.67 years.

The goodwill paid of R$ 2,636,426 comprises the value of future economic benefits arising from synergies expected from the acquisition. Goodwill is allocated on a consolidated basis as the assets acquired and liabilities assumed bring benefits to the business as a whole. There is no expectation that the goodwill recognized will be deductible for tax purposes until the corporate merger of the company Cozani takes place, which should occur throughout 2023.

Other contractual obligations

As a result of certain contractual provisions upon the acquisition of Cozani, TIM withheld the amount equivalent to 10% of the transaction Closing Price. On March 31, 2023, this amount reached R$ 712 million (R$ 671 million on December 31, 2022) and, due to the preliminary decision of the 7^th Corporate Court of the Judicial District of Rio de Janeiro, the amount is in a judicial deposit account until further decision by the Court of Arbitration.

Also, at the time of the acquisition of Cozani, there were certain contractual provisions linked to the fulfillment of migration targets by the Oi Group, in the amount of R$ 77 million. The fulfillment of these targets is under the evaluation of the Company’s Management.

On March 31, 2023, both obligations reached the total amount of R$ 789 million (R$ 748 million on December 31, 2022).

NOTES TO THE QUARTERLY INFORMATION

(In thousands of Reais, except as otherwise stated)

Preparation basis and presentation of individual and consolidated quarterly information

The individual and consolidated quarterly information was prepared and is being presented according to the accounting practices adopted in Brazil, which comprises the CVM standards and pronouncements, guidance and interpretations issued by the Accounting Pronouncement Committee (“CPC”) and in compliance with the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB).

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 provision for lawsuits and administrative proceedings that are fully classified as non-current.

On March 31, 2023, the Company reported a profit of R$ 412,436. The Company’s current liabilities exceeded total current assets by R$ 3,399,104, caused by the acquisition of Cozani and payment of obligations related to the 5G license. The Company understands that the aforementioned investments will bring relevant benefits and operational efficiency. On March 31, 2023, the Company’s shareholders’ equity is positive by R$ 25,215,516.

In connection with the preparation of this quarterly information, Company’s Management made analyses which confirms that the operating cash flow is positive; therefore, there is no evidence of uncertainties about the going concern.

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

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

NOTES TO THE QUARTERLY INFORMATION

March 31, 2023

(In thousands of Reais, except as otherwise stated)

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 flow 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 functional currency of the Company, its associated company and subsidiary.

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

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 Group's strategy is focused on optimizing results, and all the operating activities of the Group are concentrated in TIM and its subsidiary Cozani. 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.

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

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

NOTES TO THE QUARTERLY INFORMATION

March 31, 2023

(In thousands of Reais, except as otherwise stated)

transferred to the Group. Consolidation is interrupted beginning as of the date in which the Group no longer holds control.

If the Group loses control exercised over a subsidiary, the corresponding assets (including any goodwill) and liabilities of the subsidiary are written-off at their book values on the date the control is lost, and the write-off of the book value of any non-controlling interests on the date when control is lost (including any components of other comprehensive income attributed to them) also occurs. Any resulting difference as a gain or loss is recorded in income (loss). Any retained investment is recognized at its fair value on the date control is lost.

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.

The Company’s consolidation base on March 31, 2023 includes the wholly-owned subsidiary Cozani, which is mainly engaged in the provision of telecommunications services, headquartered in Rio de Janeiro, Brazil. The company holds 100% interest, due to the acquisition of this company, as described in Note 1.

Quarterly Information as of March 31, 2023 does not present: statements of income, statements of comprehensive income, statements of value added and statements of consolidated cash flows, given that the acquisition of Cozani took place from April 2022, as Note 1.

Business combination and goodwill

Business combinations are accounted for under the acquisition method. The cost of an acquisition is measured for the consideration amount transferred, which is valuated on fair value basis on the acquisition date, including the value of any non-controlling interest in the acquiree, regardless of their proportion. For each business combination, the buyer must measure the non-controlling interest in the acquired business at the fair value of based on its interest in the net assets identified in the acquired business. Costs directly attributable to the acquisition are accounted for as expense when incurred.

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 transferred consideration of the Company's interest in the acquired identifiable net assets, is recorded as goodwill. Should the consideration transferred be less than the fair value of the net assets of the acquired subsidiary, the difference is

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

NOTES TO THE QUARTERLY INFORMATION

March 31, 2023

(In thousands of Reais, except as otherwise stated)

recognized directly in the statement of income as a revenue once concepts and calculations applied are reviewed.

On acquiring a business, the Group assesses the financial assets and liabilities assumed in order to rate and to allocate them in accordance with contractual terms, economic circumstances and pertinent conditions on the acquisition date, which includes segregation by the acquired entity of built-in derivatives existing in the acquired entity’s host contracts.

Any contingent payments to be transferred by the acquiree will be recognized at fair value on the acquisition date. Subsequent changes to the fair value of the contingent consideration which is deemed to be an asset or liability should be recognized in accordance with CPC 48 in the statement of income.

Initially, goodwill is initially measured as being the excess of consideration transferred in relation to net assets acquired (acquired identifiable assets and assumed liabilities) measured at fair value on acquisition date. If consideration is lower than fair value of net assets acquired, the difference must be recognized as gain in bargain purchase in the statement of income on the acquisition date.

After initial recognition, the goodwill is carried at cost less any accumulated loss for the impairment losses. For impairment testing purposes, goodwill acquired in a business combination is, from the acquisition date, allocated to each cash-generating units of the Group that are expected to benefit by the synergies of combination, regardless of other assets or liabilities of the acquiree being allocated to those units.

When the goodwill is part of a cash generating unit and a portion of this unit is disposed of, the premium associated with the disposed portion should be included in the cost of the operation when calculating gains or losses in the disposal. The goodwill disposed under these circumstances of this operation is determined based on the proportional values of the portion disposed of, in relation to the cash generating unit maintained.

The Group measures the lease liabilities assumed at the present value of the remaining payments as if the lease agreement acquired were a new lease agreement at the acquisition date. Right-of-use assets were measured at an amount equivalent to the lease liabilities and adjusted to reflect the favorable or unfavorable terms of these leases compared to market terms. Considering that the off-market nature of said lease is reflected in the right-of-use asset, the Group does not recognize separately an intangible asset or liability relating to favorable or unfavorable terms in relation to market value.

Approval of quarterly information

This individual and consolidated quarterly information was approved by the Company's Board of Directors on May 8, 2023.

(In thousands of Reais, except as otherwise stated)

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 period ended March 31, 2023.

Amendments to CPC 37 (R1), CPC 48, CPC 29, CPC 27, CPC 25 and CPC 15 (R1).

The amendments to the above pronouncements are due to the annual changes related to the cycle of improvements between 2018 and 2020, such as:

•

Onerous Contracts – Cost of Fulfilling a Contract;

•

Property, Plant and Equipment – Proceeds before Intended Use; and

•

References to Conceptual framework.

The validity of these proposed changes must be established by regulatory agencies that approve them and to fully comply with international accounting standards, the entity must apply them in annual periods beginning on or after January 01, 2022.

Onerous Contracts – Cost of Fulfilling a Contract

An onerous contract is a contract under which the unavoidable costs of fulfilling the obligations arising from the contract (i.e., costs that the Group cannot avoid since it has the contract) exceed the expected economic benefits to be received.

The amendments specify that, when assessing whether a contract is onerous or loss-making, an entity needs to include costs that directly relate to a contract to supply goods or services, including incremental costs (for example, direct labor costs and materials) and an allocation of costs directly related to contract activities (for example, depreciation of equipment used to fulfill the contract and costs of managing and supervising the contract). General and administrative costs are not directly related to a contract and are excluded unless explicitly charged to the counterparty under the terms of the contract.

The Group evaluated the contracts and did not identify material changes in the quarterly information.

Property, Plant and Equipment – Proceeds before Intended Use;

The amendment preclude entities from deducting from the cost of a property, plant and equipment item any proceeds from sales of produced items in bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management.

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

NOTES TO THE QUARTERLY INFORMATION

March 31, 2023

(In thousands of Reais, except as otherwise stated)

Instead, an entity recognizes the products of selling the items, and the costs of producing the items, in the statement of income.

Under the transition rules, the Group applies the amendments retrospectively only to property, plant and equipment items available for use or after the beginning of the earliest period presented when the entity first applies the amendment (the date of first-time adoption).

These changes had no impact on the Group’s individual and consolidated quarterly information as there were no sales of such items produced by property, plant and equipment made available for use or after the beginning of the earliest period presented.

References to the Conceptual Framework

The amendments replace a reference to an earlier version of the IASB Conceptual Framework with a reference to the current version issued in March 2018, without materially changing its requirements.

The amendments add an exception to the recognition principle of IFRS 3/CPC 15 (R1) Business Combinations to avoid issuing potential ‘day 2’ gains or losses arising from liabilities and contingent liabilities that would be within the scope of IAS 37/CPC 25 Provisions, Contingent Liabilities and Contingent Assets or IFRIC 21 Levies, if incurred separately. The exception requires entities to apply the criteria in IAS 37 or IFRIC 21, respectively, rather than the Conceptual Framework, to determine whether a present obligation exists at the acquisition date.

The amendments also add a new paragraph to IFRS 3 to clarify that contingent assets do not qualify for recognition on the acquisition date.

Pursuant to the interim provisions, the Group applies the amendments prospectively, i.e., for business combinations that occur after the start of the annual reporting period in which it first applies the amendments (the date of first-time adoption).

These changes had no impact on the Group’s consolidated quarterly information since there were no assets, liabilities or contingent liabilities within the scope of these changes that arose during the period.

IFRS 1 First-time Adoption of International Financial Reporting Standards - Subsidiary as first-time adopter

The amendment allows a subsidiary that chooses to apply paragraph D16(a) of IFRS 1/CPC 37 (R1) - First-time Adoption of International Accounting Standards to measure cumulative translation differences using the amounts reported in the consolidated quarterly information of the parent company,

based on the parent company’s transition date to IFRS, if no adjustments have been made for consolidation procedures and for the effects of the business combination in which the parent company acquired the subsidiary. This amendment also applies to an associate or joint venture that elects to apply paragraph D16(a) of IFRS 1.

These changes had no impact on the Group’s consolidated quarterly information as it is not a first-time adopter.

IFRS 9/CPC 48 Financial Instruments - Rates in the ’10 percent’ test for writing-off financial liabilities

The amendment clarifies the rates that an entity includes when assessing whether the terms of a new or modified financial liability are materially different from the terms of the original financial liability. These rates include only rates paid or received between the borrower and the lender, including rates paid or received by the borrower or the lender on behalf of the other.

In accordance with the interim provisions, the Group applies the amendment to financial liabilities that are modified or exchanged on or after the beginning of the annual reporting period in which the entity first applies the amendment (the date of first-time adoption). These changes had no impact on the Group’s consolidated quarterly information, as there were no changes to the Group’s financial instruments during the period.

The following new standards were issued by Comitê de Pronunciamentos Contábeis [Accounting pronouncements committee] (CPC) and the International Accounting Standards Board (IASB), but are not in effect for the period ended on March 31, 2023.

Amendments to IAS 1: Classification of Liabilities as Current or Non-current (equivalent to revision 20 of the Accounting Pronouncements Committee)

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 changes enlighten:

•

What is the meaning of a right to defer the settlement;

•

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 the terms of a liability would not affect its classification only if a derivative embedded in a convertible liability was an equity instrument

Amendments are valid for periods started on January 1, 2023 and must be applied on a retrospective basis. The Group currently assesses the impact that the changes will have on current practice and whether existing loan agreements may require renegotiation.

Amendments to IAS 8: Definition of Accounting Estimates

(equivalent to revision 20 of the Accounting Pronouncements Committee)

In February 2021, IASB issued amendments to IAS 8/CPC 23, in which the definition of ‘accounting estimates’ is introduced. The amendments clarify the difference between changes in accounting estimates and changes in accounting policies and errors. Additionally, they clarify how entities use measurement and input techniques to develop accounting estimates.

The amendments will be effective for periods beginning on or after January 1, 2023, and will apply to changes in accounting policies and estimates that occur on or after the beginning of that period. If disclosed, early adoption is allowed.

Amendments are not expected to have a significant impact on the Group’s financial statements.

Amendments to IAS 1 and IFRS Practice Statement 2: Disclosure of Accounting Policies (equivalent to revision 20 of the Accounting Pronouncements Committee)

In February 2021, IASB issued amendments to IAS 1/CPC 26 (R1)) and IFRS Practice Statement 2 Making Materiality Judgments, in which guides and examples are provided to help entities to apply materiality judgment to the disclosure of accounting policies. The aim of amendments is to assist entities in the disclosure of accounting policies that are most useful by replacing the requirement for disclosure of significant accounting policies to material accounting policies and adding guides about how entities should apply the concept of materiality to make decisions about the disclosure of accounting policies.

The amendments to IAS 1 are applicable for periods started as of or after January 1, 2023, with early adoption allowed. Since the amendments to Practice Statement 2 provide non-mandatory guides about the application of material definition to the accounting policy information, an adoption date is not required for this amendment.

The Group is currently revisiting the accounting policy disclosures to confirm that they are consistent with the required changes.

Amendments to IAS 12: Deferred Tax Related to Assets and Liabilities Arising from a Single Transaction (equivalent to the Committee’s revision 20 of accounting pronouncements)

(In thousands of Reais, except as otherwise stated)

In May 2021, the Board released amendments to IAS 12, which narrow the scope of the initial recognition exception under IAS 12 so that it no longer applies to transactions that give rise to equal taxable and deductible temporary differences.

The amendments shall apply to transactions occurring in annual periods beginning on or after the earliest comparative period presented. Furthermore, at the beginning of the earliest comparative period presented, a deferred tax asset (provided there is sufficient taxable profit available) and a deferred tax liability must also be recognized for all deductible and taxable temporary differences associated with leases and decommissioning obligations.

The Group is currently assessing the impact of these changes.

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 on the base date of 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 book values of assets and liabilities for the fiscal period, are covered below.

(a) Impairment loss on non-financial assets and investments in subsidiary and associated company.

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 16) and its tangible and intangible assets.

Net investments in the subsidiary and associated company are valued after applying the equity method to determine whether there is any objective evidence of impairment. The recoverable amount of an investment in an associated company must be determined for each investment, unless the associated company does not generate cash inflows on an ongoing basis that are largely independent of those generated by the entity’s other assets. The investment in an associated company was valued as described in Note 14.

(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 25).

(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 39).

(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 29).

(f) Leases

The Company has a significant number of the lease contracts in which it acts a lessee (Note 17), and with the adoption of the accounting standard IFRS 16 / CPC 06 (R2) – Leases, on January 1, 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; and (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. 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.

(g) Fair value of the intangible assets

Intangible assets are measured at historical cost less accumulated amortization and impairment losses.

The cost of intangible assets acquired in a business combination corresponds to their fair value at acquisition date. After the initial recognition, the intangible assets are stated at cost, less accumulated amortization and impairment losses.

Due to the scenario of severe stress observed recently in the marketable securities’ market, the Company opted to reduce its position in funds, migrating a large part of the funds to fixed income operations (Bank Deposit Certificates - CDBs) with first-class banks.

(i)As of December 2017, the Company, with the aim of using tax deductibility benefit for income tax purposes, started investing in the National Film Industry Financing Fund (FUNCINE). The average remuneration in 2023 was 0.32% p.a. (0.09% p.a. in 2022).

(ii) Fundo Soberano is composed only of federal government bonds. The average remuneration in 2023 was 99.53% p.a. of the variation of the Interbank Deposit Certificate - CDI (99.94% on December 31, 2022).

(iii) In August 2017, the Company invested in open FIC's (Quota Investment Fund). Funds are mostly made up of federal government bonds and papers from financial institutions, mostly AAA (highest quality). The average remuneration of FICs in 2023 was 87.30% p.a. of the variation of the Interbank Deposit Certificate - CDI (107.19% p.a. on December 31, 2022).

(a) Government bonds are fixed income financial instruments issued by the National Treasury to finance the activities of the Federal Government.

(b) The CDB operations are emitted by the banks with the commitment of stock buyback by the bank itself and with predetermined taxes.

Trade accounts receivable

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. Trade accounts receivable are initially recognized at fair value and, subsequently, measured at amortized cost using the effective interest rate method less 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, 2023 and December 31, 2022.

The average rate considered in calculating the present value of accounts receivable recorded in the long term is 0.58% p.m. (0.58% p.m. on December 31, 2022).

i) In September 2021, the Federal Supreme Court (STF), with general repercussions, established an understanding for the non-levy of Corporate Income Tax (IRPJ) and Social Contribution (CSLL) on the monetary restatement using the SELIC rate in cases of undue payment. The specific TIM lawsuit is still pending judgment, TIM recorded its best estimate to date, in the amount of R$ 624 million recorded in current and non-current assets (R$ 607 million on December 31, 2022) since the likelihood of a favorable outcome for the Company becomes probable. The Company is awaiting the final decision.

(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, the Company expects to use these credits in the next 12 months.

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 million relates to principal and R$ 1,228 million was inflation adjustment.

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 May 2021, the Brazilian Supreme Court (STF) ended the discussion regarding the credit rights of the companies, defining in the judgment of Motions for Clarification that the exclusion of ICMS from the PIS and COFINS calculation basis is valid as of March 15, 2017, when the general repercussion thesis (Topic 69) was established, in the judgment of Special Appeal (RE) No. 574706.

Deferred income tax and social contribution

Deferred income tax and social contribution are recognized on (1) tax losses and accumulated tax loss carryforwards; and (2) temporary differences arising from differences between the tax basis of assets and liabilities and their book values in the quarterly information. 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.

The balances of deferred income tax and social contribution assets and liabilities are shown in the balance sheet at their net amounts, when there is both a legal right and an intention to offset them at the time when the current taxes are ascertained, usually in relation to the same legal entity and the same taxation authority. Thus, deferred tax assets and liabilities belonging to different entities are in general shown separately, not at their net amounts.

On March 31, 2023 and December 31, 2022, 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.

(i) Mainly represented by the Fistel fee (TFF) for the financial years 2020, 2021, 2022 and 2023 of TIM S.A. at a parent company level and, at a consolidated level, the TFF referring to Cozani's 2022 financial year is also added. The Operating Inspection Fee (TFF) for the years 2020, 2021, 2022 and 2023 of TIM S.A. and TFF for 2022 of Cozani had its payments suspended by virtue of an injunction and, therefore, still do not have a specific date for payment. See Note 22 for details.

(ii) Represented by the goodwill on the business combination of companies TIM Fiber RJ and SP acquired by TIM in 2012, partially realized in November 2021 after the completion of the transaction for the sale of 51% of the equity interest in I-Systems to IHS, as described in Note 1.

(iii) Represents the addition of new contracts. The temporary difference of the IFRS 16 contracts is due to the difference in the timing of recognition of the accounting and tax expense, under the terms of the current legislation.

(iv) As of the 1Q20, TIM S.A. excludes the portion of acceleration of depreciation of movable assets belonging to property, plant and equipment 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$ 713 million until March 31, 2023 (R$ 663 million up to December 31, 2022) and applied as of January 1, 2020.

(v) Refers to deferred charges on the fair value of the non-controlling interest calculated in the sale of Fiber Co (currently I-Systems), which took place in November 2021, from TIM S.A. to IHS Fiber Brasil - Cessão de Infraestruturas Ltda (see Note 14).

(vi) Represents the deferred charges recorded, referring to the impairment of tangible assets.

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.

Considering that Cozani does not have a tax base history, no deferred tax credits were recognized on tax losses and negative basis of social contribution in the amount of R$ 144,167 (R$ 129,954 on December 31, 2022), referring to Cozani.

The Company used credits from tax losses and the negative basis of social contribution in the amount of R$ 59,023 throughout 2023 (R$ 123,948 in 2022).

I-Systems

In December 2020, the company Fiber Co (current I-Systems) was established and was 100% controlled by TIM S.A. In November 2021, as a result of the spin-off of net assets of the broadband business and the creation of I-Systems (formerly FiberCo) with subsequent sale of 51% of its equity interest on behalf of IHS, TIM S.A. assessed the transaction as a loss of control and stopped consolidating it, recording the investment in an associated company, in the amount of R$ 1,612,957 at fair value for the remaining minority interest (non-controlling) of 49%.

TIM S.A. has 49% (49% on December 31, 2022) in the share capital of I-Systems. Therefore, between December 2020 and October 2021, Fiber Co was a subsidiary of TIM S.A., becoming an associated company as of November 2021, a condition that remains until now.

if applicable). Depreciation is calculated based on the straight-line method over terms that consider the expected useful lives of the assets and their residual values. On March 31, 2023 and December 31, 2022, the Company has no indication of impairment in its property, plant and equipment. Property, plant and equipment values recorded in the acquisition of Cozani were adjusted to its recoverable values.

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 book value at the time of the transaction and are recognized in “other operating expenses (revenue), net” in the statement of income.

Intangible assets

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.

Financial charges on funds raised generically (with no specific allocation), used to obtain a qualifying asset, which is an asset that necessarily demands a substantial period of time to become ready for intended use is capitalized as part of this asset’s cost when it is probable that will result in future economic benefits to the Entity and such costs can be reliably measured. Within this concept, we had the capitalization of charges for the 700MHz 4G license between 2014 and 2019 and we currently have the capitalization of charges on the acquisition of the 5G license for the radio frequency not readily available and other obligations related to such radio frequency. Said capitalization occurs until the asset is considered available for use by Management, and as of that date onwards, capitalization of interest and charges on this asset ends. These costs are amortized over the estimated useful lives.

The values of permits for the operation of SMP and rights to use radio frequencies, as well as software, goodwill and others are demonstrated as follows:

The costs associated with maintaining software are recognized as expense, as incurred. Development costs that are directly attributable to software product design and testing, and are identifiable and exclusive, controlled by the Group, are recognized as intangible assets when the capitalization criteria are met.

Directly attributable costs that are capitalized as part of the software product are related to employee costs directly allocated in its development.

(d) Goodwill registered

(d.1) Goodwill on the acquisition of Cozani

As described in Note 1.2.1, in April 2022 the Company acquired 100% of Cozani, with a total consideration paid of R$ 7,211,585 and identifiable assets, net of liabilities assumed, at a fair value of R$ 4,575,159. Therefore, having a remaining amount of goodwill allocated from R$ 2,636,426, which is recorded on March 31, 2023.

The Company describes the accounting practice adopted in business combinations in the Note 2e that initially, goodwill is initially measured as being the excess of consideration transferred in relation to net assets acquired (acquired identifiable assets and assumed liabilities).

After initial recognition, the goodwill is carried at cost less impairment losses (if any). For purposes of impairment testing, goodwill acquired in a business combination is, as of the acquisition date, allocated to the respective cash-generating units that are expected to benefit from the combination. In the case of the TIM group, the goodwill was allocated to the mobile cash generating unit, which is the only one identified so far.

(d.2) Goodwill registered in previous years

The Company has the following goodwill, based on the expected future profitability on March 31, 2023 and December 31, 2022.

Goodwill from TIM Fiber SP and TIM Fiber RJ acquisitions – TIM Celular S.A. (merged by Intelig, current TIM S.A.) acquired, at the end of 2011, the companies Eletropaulo Telecomunicações Ltda. (which subsequently had its trade name changed to TIM Fiber SP Ltda. – “TIM Fiber SP”) and AES Communications Rio de Janeiro S.A. (which subsequently had its trade name changed to TIM Fiber RJ S.A. – “TIM Fiber RJ”). 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.

In November 2021, the Company concluded the drop-down of liquid assets related to the residential broadband business linked to the secondary network infrastructure to the wholly-owned subsidiary FiberCo and sold 51% of the equity interest in FiberCo, currently named I- Systems, on behalf of IHS. Currently, due to the closing of the transaction, TIM S.A. wrote-off about 90% of the total goodwill recorded in the acquisition of TIM Fiber SP Ltda. and TIM Fiber RJ S.A. in the amount of R$ 1,051,477. As a result, IHS currently holds 51% of the share capital of I-Systems, with TIM S.A. having a minority (non-controlling) interest of 49% in I-Systems. Consequently, with the closing of this deal in November 2021, the goodwill initially recorded on the acquisition of the companies Fiber RJ and Fiber SP was reduced to R$ 108,171 and this balance was recorded on March 31, 2023 and December 31, 2022.

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.

The methodology and assumptions used by Management for the aforementioned impairment test is 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 highlighting that the group’s results are essentially represented by TIM S.A., but with the acquisition of Cozani in 2022, it started generating results in the TIM S.A. as of April 30, 2022. The Company understands that the consolidated results of TIM S.A.

represent a single cash-generating unit for purposes of impairment testing of assets with indefinite useful lives, in accordance with IAS 36/CPC 01.

On December 31, 2022, 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 book value of the cash generating unit.

The fair value of Tier 1 instruments comprises instruments traded on active markets and based on market prices quoted at 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.

Company’s shares are traded on B3 – Brasil, Bolsa, Balcão (“B3”) 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.

In 2022, 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 book value. Therefore, being the fair value higher than the book value, 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 book value in 2021 were irrelevant and, also, its effects on the result of the Company. 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, 2023, the Company carried out the analysis of all tangible, intangible assets and investments and did not identify any impairment indicators.

(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.

(f) Authorizations

4G License

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 fell 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 and 2019.

5G License

In 2021, there was a record regarding the acquisition of the 5^th Generation (“5G”) mobile telephony radio frequencies.

In November 2021, TIM participated in the 5G Auction and was the winner of several lots in the 2.3GHz, 3.5Ghz and 26Ghz radio frequency bands. These licenses will be paid over a period of 10 to 20 years, subject to restatement at the Selic rate. In December 2021, the Company signed the Terms of Authorization for these radio frequencies, generating the accounting of an intangible asset related to the licenses in the amount of R$ 884 million and the obligations related to said licenses (among them, disbursements with costs of the public notice and disbursement obligations with the management entities described below) in the amount of R$ 2,680 million.

Aiming to fulfill the additional obligations, the Company foresees, according to the notice, that there will the constitution of managing entities, which are only intended to fulfill the commitments provided for in the Auction. The companies that win the Auction must disburse only the amounts provided for in the public notice so that such entities comply with the defined obligations. There are additional obligations provided for related to 3.5GHz radio frequency (the band cleaning obligation, interference solution, among others), which must be complied with by the Band Management Entity (“EAF”), and related to 26GHz radio frequency (connectivity project for public schools), which must be complied with by the Entity Managing the Connectivity of Schools (“EACE”).

On the signature date of the terms, in December 2021, the 2.3GHz and 26GHz radio frequencies were readily available for use by the Company (operating assets), generating the registration in 2021 in “Authorizations” of the amounts related to the licenses (R$ 614 million) and the obligations related to the 26GHz license, which will be fulfilled through EACE (R$ 550 million). The disbursements with EACE (R$ 633 million), provided for in the Public Notice, will occur in 5 semi-annual installments between 2022 and 2024, and are monetarily restated by the IGP-DI. The Company evaluated the application of the concept of adjustment to present value (“AVP”) upon initial recognition (R$ 83 million).

The 3.5GHz radio frequency was not readily available, requiring spectrum cleaning activities to be available for use, and, thus, it was registered in

assets in progress (R$ 270 million). Therefore, the obligations related to this activity, to be carried out by EAF (R$ 2,104 million) were also recorded under assets in progress. The disbursements with the EAF, as provided for in the Public Notice, were restated by the IGP-DI until the disbursement dates. Such disbursements took place in 2 installments in 2022 (R$ 1,090 million in February and R$ 1,133 million in May) to EAF.

Furthermore, as described above, the Company capitalizes loan costs for qualifying assets that require a substantial period of time to be in a condition for use as intended by Management. This concept includes the 3.5GHz radio frequency. On March 31, 2023, the Company recorded R$ 82 million in intangible assets referring to interest calculated based on the Selic rate (R$ 259 million in 2022) incurred on the 3.5GHz radio frequency and did not capitalize the inflation adjustments of amounts due to EAF in 2023 since there is no further balance to disburse with this entity (R$ 99 million in 2022). Said balances are recorded under assets in progress.

Thus, the total effect on the Company’s intangible assets on March 31, 2023 referring to 5G radio frequencies and related obligations was R$ 3,930 million (R$ 3,866 million in 2022), of which R$ 2,836 in assets in progress (R$ 2,753 in 2022) and R$ 1,094 million in Authorizations (R$ 1,113 million in 2022).

Leases

When entering into a contract, the Company assesses whether the contracts signed are (or contain) a lease. An agreement is (or contains) a lease if it transmits the right to control the use of an identified asset for a period of time in exchange for consideration.

Leases whose the Company is a lessee are capitalized at the lease's commencement at the lower of the fair value of the leased asset (right-of-use) 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.

ii) Sale and leaseback of Towers

The Company entered into two Sales Agreements with American Tower do Brasil Cessão de Infraestruturas Ltda. (“ATC”) in November 2014 and January 2015 for up to 6,481 telecommunications towers then owned by TIM Celular, for an amount of approximately R$ 3 billion, and a Master Lease Agreement (“MLA”) for part of the space on these towers for a period of 20 years from the date of transfer of each tower, under a sale and leaseback transaction, with a provision for monthly rental amounts depending on the type of tower (greenfield or rooftop). The sales agreements provided for the towers to be transferred in tranches to ATC, due to the need to meet certain conditions precedent.

In total, 5,873 towers were transferred, being 54,336 and 5,483 in the years 2017, 2016 and 2015, respectively. This transaction resulted in a sales amount of R$ 2,651,247, of which R$ 1,088,390 was booked as deferred revenue and will be amortized over the period of the contract (Note 24).

The discount rates used at the date of the transactions, ranging from 11.01% to 17.08% per annum, were determined based on observable market transactions that the company (the lessee) would have to pay on a similar lease and/or loan.

(iii) It is substantially represented by lease transactions in transmission towers.

(iv) Other leases:

In addition to lease agreements mentioned above, the Company also has lease agreements that qualify within the scope of IFRS 16 / CPC 06 (R2).

The present value, principal and interest value on March 31, 2023 for the above contracts was estimated month-to-month, based on the average incremental rate of the Company’s loans, namely 14.08% (13.24% in 2022).

Lease agreements within the scope of IFRS 16/CPC 06 (R2) acquired through the acquisition from Cozani were remeasured on the acquisition date to reflect the Company’s expectation of the lease term and average incremental rate of loans. The amount recorded on the acquisition date was R$ 2,929,449.

The lease amounts considered low-value or short-term (less than 12 months) were recognized as rental expenses and totaled R$ 8,377 on March 31, 2023 (R$ 40,723 on December 31, 2022).

Other amounts recoverable

These refer to Fistel credit amounts arising from the reduction of the client base, which may be offset by future changes in the base, or used to reduce future obligations, and are expected to be used in the reduction of the TFF contribution (operating supervision fee) due to Fistel.

On March 31, 2023, this credit is R$ 30,115 (R$ 26,519 on December 31, 2022).

Accounts payable to suppliers are obligations payable for goods or services that were acquired in the usual course of business. They are initially recognized by fair value and subsequently measured by amortized cost using the effective interest rate method. Given the short maturity of these obligations, in practical terms, they are usually recognized at the value of the corresponding invoice.

Fair value of loans

In Brazil, there is no consolidated long-term debt market with the characteristics verified in the financing obtained from KFW Finnvera, which has the Finnish development agency Finnvera as guarantor. Both are financing for the purchase of equipment and, therefore, have a character of subsidy and promotion of commercial activity between the company and certain suppliers. For the purposes of fair value analysis, considering the characteristics of this transaction, the company understands that its fair value is equal to that recorded on the balance sheet.

With respect to proceeds contracted with the Bank of Nova Scotia, BNP Paribas, Debentures and BNDES and BNB, the fair value of these loans is considered to be the present value of the long position of the swap contracts that protect the Company from changes in exchange rates and interest. The fair value of the operations on March 31, 2023 is, respectively, R$ 1,502,802, R$ 39,244, R$ 1,753,234, R$ 371,009 and R$ 225,777.

strengthening of transport and access networks, among others. In addition, it contemplates the additional commitment to bring mobile broadband, through the 4G network, to 350 municipalities with less than 30 thousand inhabitants thus reaching more than 3.4 million people. The new infrastructure was implemented in three years – more than 99% of the municipalities were served in the first two years and the remaining three municipalities were served in November 2022 – with the Company guaranteeing the sharing regime with the other operators.

With the closing of the 1st TAC Year, the following commitments were certified by the Agency: Reparation, Fund for the Defense of Diffuse Rights – FDD (phase 1) and Notifications; Numbering; Interconnection; INCOME TAX; IGQ; Impediment; Internal controls; LTE 700 MHz; New 4G; Backhaul; Licensing backlog; Scope Commitment; Personal assistance; Digital relationship; and Additional Commitments.

In June 2022, TIM concluded the 2^nd year of the Conduct Adjustment Term (TAC) entered into with Anatel, having carried out the activities planned for strict compliance with the purpose of achieving the associated targets. In September 2022, the Impediment Commitments, Internal Controls and Additional Commitments received certificates from the Agency related to the 2nd year target.

In October 2022, TIM and Anatel signed the Amendment to renegotiate the commitment related to Quality Indicators. Thus, the Perceived Quality Index (IQP) will be adopted to replace the General Quality Index (IGQ), discontinued by the Agency.

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. The Company has been complying with the TAC implementation schedule without the need for any additional obligations in March 2023.

Regarding the extension of the term of the authorizations to use the radio frequencies associated with the SMP, the Company 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, and subsequent years, the revenues obtained with Value-Added Services, among others. 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 Company will proactively transfer its effects to its customers, according to the nature of its plans. However, such transfer depends on systemic developments that are in progress and will be concluded during the course of 2023.

b.2 Long-term incentive plan

The balances recorded under these items represent the Company's expenses related to the long-term incentive program granted to employees (Note 28).

c. Profit reserves

c.1 Legal Reserve

It refers to the allocation of 5% of the net profit for the year ended December 31 of each year, until the Reserve equals 20% of the share capital, excluding from 2018 the balance allocated to the tax incentive reserve. In addition, the company may cease to constitute the legal reserve when this, added to the capital reserves, exceeds 30% of the share capital.

This Reserve may only be used to increase capital or offset accumulated losses.

c.2 Statutory reserve for expansion

The formation of this reserve is foreseen in Paragraph 2 of art. 46 of the bylaws of the company and is aimed at the expansion of social business.

The balance of profit that is not compulsorily allocated to other reserves and is not intended for the payment of dividends is allocated to this reserve, which may not exceed 80% of the share capital. Reaching this limit, it will be up to the General Meeting to decide on the balance, distributing it to shareholders or increasing capital.

c. 3 Tax Benefit Reserve

The Company enjoys tax benefits that provide for restrictions on the distribution of profits. According to the legislation that establishes these tax benefits, the amount of tax that is no longer paid due to exemptions and reductions in the tax burden may not be distributed to members and will constitute a reserve of tax incentive of the legal entity. Such a reserve may only be used to absorb losses or increase the share capital. On March 31, 2023, the accumulated amount of benefits enjoyed by the Company amounts to R$ 2,124,411 (R$ 2,124,411 on December 31, 2022).

The said tax benefit basically corresponds to the reduction of the Corporate Income Tax (IRPJ) incident on the profit of the exploitation calculated in the units encouraged. The Company operates in the area of the defunct Superintendence of development of the Amazon (SUDENE / SUDAM), being the tax incentive awards granted by state of the Federation, for a period of 10 years, subject to renewal.

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.

For the 2018-2020 and 2021-2023 plan, the term of validity has the same periodicity of 3 years related to its vesting. These Plans, in addition to considering the transfer of shares, also provides for the possibility of making payment to participants of the equivalent amount in cash.

Net revenue

Revenue from services rendered

The principal service revenue derives from monthly subscription, the provision of separate voice, SMS and data services, and user packages combining these services, roaming charges and interconnection revenue. The revenue is recognized as the services are used, net of sales taxes and discounts granted on services. This revenue is recognized only when the amount of services rendered can be estimated reliably.

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

NOTES TO THE QUARTERLY INFORMATION

March 31, 2023

(In thousands of Reais, except as otherwise stated)

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 and 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 net service revenue item also includes revenue from new partnership agreements (financial, education and advertising), and the amount of revenue recognized in the period ended March 31, 2023 is R$ 31,581 (R$ 35,469 on March 31, 2022).

Regarding the financial partnership, the Arbitration Procedure No. 28/2021/SEC8 was filed before the Arbitration and Mediation Center of the Brazil-Canada Chamber of Commerce (“CCBC” and “Arbitration Procedure”, respectively), by TIM against Banco C6 S.A., Carbon Holding Financeira S.A. and Carbon Holding S.A (together, “Defendants”), through which the interpretation of certain clauses in the contracts that rule the partnership between the parties will be discussed. In case of loss, the partnership may be terminated.

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 mainly verified the existence of the following 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 customer; and the asset is considered transferred when or as the customer 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.

Cost to obtain contract

All incremental costs related to obtaining a contract (sales commissions and other costs of acquisition from third parties) are recorded as prepaid expenses and (as described in Note 11) amortized over the same period as the revenue associated with this asset. Similarly, certain contract compliance costs are also deferred to the extent that they relate to performance obligations under the customer agreement, i.e. when the customer obtains control over the asset.

Financial instruments and risk management

Among the financial instruments registered in the Company, there are derivatives that are financial assets or liabilities measured at fair value through profit or loss. At each balance sheet date such assets/liabilities are measured at their fair value. Interest, monetary correction, foreign exchange variation and variations arising from the fair value measurement, where applicable, shall be recognized in the result when incurred, under the line of financial revenues or expenses.

Derivatives are initially recognized at fair value on the date the derivative agreement is entered into, 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 foreign exchange variation and ii) managing interest rate exposure. The Company's derivative financial instruments are specifically represented by swap and options contracts.

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) Exchange rate risks

The exchange rate risks relate to the possibility of the Company computing i) losses derived from fluctuations in exchange rates by increasing the balances of

129

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

NOTES TO THE QUARTERLY INFORMATION

March 31, 2023

(In thousands of Reais, except as otherwise stated)

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 variation. In order for these types of risks to be mitigated, the company performs: swap contracts with financial institutions with the aim of canceling the impacts arising from the fluctuation of exchange rates on the balance sheet and 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 remaining risks of foreign exchange exposure in commercial contracts.

On March 31, 2023 and December 31, 2022, 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.

(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, fixed rate and/or TLP, when such rates pose a risk to the company’s perspective of not corresponding proportionally to the rates relating to Interbank Certificates of Deposit (CDI). The Company opted to hedge the exposure linked to the IPCA arising from the issuance of debentures, financing to BNDES (FINAME) and BNB and the exposure to a fixed rate linked to the debt with BNP Paribas, all of them until maturity.

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, 2023 and December 31, 2022, 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, 2023 and December 31, 2022 or revenues from services rendered during the periods ended March 31, 2023 and 2022.

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

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 periods ended

NOTES TO THE QUARTERLY INFORMATION

March 31, 2023 and 2022. There are no customers who contributed more than 10% of the net receivables from the sale of goods as of March 31, 2023 and December 31, 2022.

(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. See Notes 17 and 21.

The liquidity and cash flow management of the Company are carried out daily to ensure that the operational cash generation and prior fund raising, when necessary, are sufficient to maintain its schedule of operational 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 performed by the Finance Executive Board, which monitors the continuous forecasts of the liquidity requirements to ensure that the Company has enough cash to satisfy its operating 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 posting losses resulting from difficulties in the redemption of short-term interest earning bank deposits 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.

Group/Company paid a share subscription premium in the amount of R$ 24.7 million. As required by IFRS 9 / CPC 48, the financial instrument must be valued at its fair value that on March 31, 2023 and December 31, 2022 corresponds to R$ 645 and R$ 624 million, respectively. The impact of the mark-to-market of the stock conversion option calculated, of R$ 620.3 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 revaluated and recorded in the Company’s results for the year, considering the arbitration risks disclosed in Note 29.

The long-term derivative financial instruments at March 31, 2023 are due in accordance with the following schedule:

NOTES TO THE QUARTERLY INFORMATION

March 31, 2023

(In thousands of Reais, except as otherwise stated)

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 through the use of 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 relevant information is not based on data adopted by the market, the instrument is included in Level 3.

Specific evaluation techniques used to measure the 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.

The fair values of currency derivative financial instruments and interest rates of the Company were determined by means of future cash flows (active and passive position) using the contracted conditions and bringing these flows to present value through discounts for the use of future interest rate disclosed by market sources. Fair values were estimated at a specific time, based on available information and own evaluation methodologies.

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 or indexed to the interest rate, in order to manage said exposure.

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.

Position showing the sensitivity analysis – effect of variations in the fair value of the swaps

For the purpose of identifying possible distortions arising from operations with consolidated derivative financial instruments currently in force, a sensitivity analysis was performed considering the variables CDI, US dollar (USD), Libor and IPCA, individually, in three distinct scenarios (probable, possible and remote), and their respective impacts on the results obtained.

Our assumptions basically observed the individual effect of the CDI, USD, Libor and IPCA variation used in the transactions as the case may be, and for each scenario the following percentages and quotes were used:

Sensitivity scenario		Fair value in USD, EUR, BRL and IPCA⁽¹⁾	A) ∆ Accumulated variation in debt	Fair value of the long position of the swap (+)	Fair value of the passive tip of the swap (-)	Swap result	B) ∆ Accumulated variation in swap	C) Final Result (B-A)

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 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, 2023 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.

Capital Management

The Group's objectives in managing its capital are to safeguard its business continuity capacity to offer return to shareholders and benefits to the other stakeholders besides maintaining a capital structure to reduce this cost. To maintain or adjust the group's capital structure, management may review the dividend payment policy, return capital to shareholders, or issue new shares or sell assets to reduce, for example, the level of debt.
