2024 First Quarter Results

FINANCIAL PERFORMANCE

OPERATING REVENUE

SOLID EXPANSION WITH CONSISTENT PERFORMANCE IN ALL MAIN REVENUE LINES

* Net Revenue normalized by the temporary effect of inefficiency of PIS/COFINS as a result of the contract signed between TIM S.A and Cozani (+R$41.0 million in 1Q23). The merger of Cozani into TIM S.A. took effect on April 1^st, 2023.

In the first quarter of 2024, Normalized Net Revenue grew by 7.3% YoY, totaling R$6,096 million. This result counted on the contribution of all main fronts, of which (i) Mobile Service Revenue grew by 7.4% YoY, leveraged by Postpaid services; (ii) Broadband Service Revenue from TIM UltraFibra grew by 9.1% YoY; and (iii) Product Revenue grew by 7.3% YoY.

2024 First Quarter Results

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

Normalized Mobile Service Revenue ("MSR") totaled R$5,577 million in 1Q24, corresponding to an increase of 7.4% YoY, mainly reflecting the positive organic performance in Postpaid. Normalized Mobile ARPU (average monthly revenue per user) reached R$30.3, the highest in the sector, represented by a expansion of 8.8% YoY - the highest growth for a 1^st quarter in the Company's history - which, once again, corroborates our strategy of increasing monetization of the customer base.

Below is the performance breakdown of each mobile customer profile:

Prepaid Revenue was almost flat (+0.4% YoY) in 1Q24, and Prepaid ARPU reached R$14.6 (+5.4% YoY). In this quarter, the line was impacted by seasonal effects (e.g., vacation period, Carnival, peak of inflation over population domestic feeding) that affected the recharge dynamics. Furthermore, the good performance in the migration of customers from Prepaid to Postpaid also had a relevant impact. The combination of these elements reduced the positive effects of the biweekly offer adjustment that occurred in 4Q23.

II.

Postpaid Revenue had good performance, growing 7.4% YoY in 1Q24, with Postpaid ARPU reaching R$42.1 (+4.1% YoY) and Postpaid ARPU ex-M2M reaching R$51.0 (+6.3% YoY). The performance is explained by (i) the tariff adjustment on Postpaid offers throughout 2023; (ii) the improvement in customer base management, reducing churn rates to 1.1% per month, of which 0.8% in Postpaid ex-M2M - one of the lowest in the Company's history; and (iii) through the ongoing migration process to higher value plans, reinforcing the attractiveness of our postpaid plans.

Interconnection Revenue (ITX) dropped by 14.6% YoY in 1Q24, due to the lower incoming traffic in the annual comparison.

Customer Platform Revenue totaled R$31 million in 1Q24, down by 1.3% YoY, due to a slower performance already expected in this line, as a result of the revision of this line's business model and the pursuit of new partnerships with exclusive offers.

2024 First Quarter Results

The Other Normalized Revenues^[1] line increased by 13.6% YoY, due to higher revenues related to readjustments on infrastructure and network sharing contracts.

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

In 1Q24, Fixed Service Revenue totaled R$332 million, up by 5.5% YoY.

TIM UltraFibra, the main line for the fixed segment, grew by 9.1% YoY in 1Q24, sustaining its growth pace and reaching the highest broadband ARPU in the Company's history, R$95.8 (+3.1% YoY). The consistent result reflects the Company's strategy to focus on the evolution of FTTH (Fiber-to-the-Home), which already accounts for over 90% of our total broadband customer base.

Breakdown of Product Revenue (net of taxes and deductions):

Product Revenue grew by 7.3% YoY, following the increase in device sales, especially those compatible with 5G technology, and equipment related to our "B2B IoT" business segment - which reflects our movement to offer greater diversification in the product portfolio in order to meet customer needs and offer greater convenience.

^[1] The Other Revenues line had a non-recurring impact of R$41.0 million in 1Q23, referring to the temporary effect of inefficiency of PIS/COFINS as a result of the contract signed between TIM S.A and Cozani, which was extinguished with the merger of Cozani.

2024 First Quarter Results

OPERATING COSTS AND EXPENSES

OPEX INCREASING AT A SLOWER PACE THAN REVENUE

* Operating Costs normalized by: non-recurring effect from the accounting for the closing price adjustment agreement for Oi's mobile assets (-R$303.4 million in 4Q23), expenses with consulting services within the scope of the acquisition project of Oi Mobile and customer migration (+R$190k in 4Q23 and +R$12.5 million in 1Q23), PIS/COFINS credits generated in the intercompany contract with Cozani (-R$17.7 million in 1Q23) and expenses with FUST/FUNTEL related to the intercompany contract with Cozani (+R$886k in 1Q23).

Normalized Operating Costs and Expenses totaled R$3,205 million in 1Q24, up by 4.4% YoY. Reported Operating Costs and Expenses also reached R$3,205 million in 1Q24, a YoY increase of 4.6%, justified by the non-recurring effects recorded in 1Q23 as indicated in the table above.

Breakdown of Normalized Costs and Expenses Performance:

Personnel costs grew by 8.7% YoY in 1Q24, impacted by salary adjustments, higher benefits, and costs related to employees' profit sharing.

The Commercialization and Advertising line fell by 5.2% YoY in 1Q24, mainly due to (i) the termination of the Temporary Service Agreement with Oi last year, which benefited the annual comparison; and (ii) lower costs with customer service, due to the higher penetration of digital services on customer caring.

The Normalized Network and Interconnection group^[2] increased by 17.4% YoY in 1Q24, as a result of a worsening in the Interconnection line, which continues to be affected by (i) higher expenses for roaming services, in line with the restructuring of the international roaming portfolio; (ii) increased spending on content providers; and (iii) higher fiber network maintenance costs due to the expansion of TIM UltraFibra during last year.

General and Administrative Expenses (G&A) fell by 10.0% YoY in 1Q24, due to lower expenses with the contracting of strategic consulting services compared to the first quarter of 2023.

^[2] The Network and Interconnection line was impacted by non-recurring items, in the amount of R$190k in 4Q23 and R$12.5 million in 1Q23, referring to consulting expenses within the scope of the migration project for customers arriving from Oi, and -R$17.7 million in 1Q23, referring to PIS/COFINS credits generated in the intercompany contract with Cozani.

2024 First Quarter Results

The Cost of Goods Sold (COGS) grew by 7.7% YoY in 1Q24, in line with the revenue evolution, following the dynamics of sales of higher average-cost devices.

The Bad Debt line increased by 3.7% YoY in 1Q24, a slight growth which was within the Company's expectation as the mix of the customer base migrates to postpaid services. However, the Bad Debt over Gross Revenue ratio reached 1.9% (vs. 2% in 1Q23).

Other Normalized Operating Expenses (Revenue)^[3] fell by 6.7% YoY in 1Q24, mainly due to lower provisions for civil contingencies, offset by higher expenses with provisions for tax contingencies.

^[3] The Other Normalized Operating Expenses (Revenue) line was impacted by non-recurring items, in the amount of -R$303.4 million in 4Q23, referring to the effect from the accounting for the closing price adjustment agreement for Oi's mobile assets, and R$886k in 1Q23, referring to expenses with FUST/FUNTEL.

2024 First Quarter Results

FROM EBITDA TO NET INCOME

ROBUST EBITDA NUMBERS: DOUBLE-DIGIT GROWTH AND MARGIN EXPANSION

* Normalized EBITDA according to the items described in the Revenue section (+R$41.0 million in 1Q23) and Costs section (-R$303.2 million in 4Q23 and -R$4.4 million in 1Q23). Net Financial Result normalized by the monetary adjustment on the non-recurring effect of the accounting for the closing price adjustment agreement for Oi's mobile assets (+R$27.5 million in 4Q23).

2024 First Quarter Results

EBITDA^[4](Earnings Before Interest, Taxes, Depreciation, Amortization and Equity in Earnings)

Normalized EBITDA totaled R$2,890 million in 1Q24, a robust increase of 10.7% YoY, supported by solid operating performance on the main business fronts. Accordingly, the Normalized EBITDA Margin reached 47.4%, representing a YoY expansion of 140 bps, recovering its high level after a period impacted by the acquisition of Oi's mobile assets.

Considering the effects of leases on EBITDA, the Normalized EBITDA-AL ("After Lease")^[5] (excluding impacts from fines related to the decommissioning of sites^[6]) grew by 20.7% YoY in 1Q24, totaling R$2,198 million, with a margin of 36.1%, which represents +400 bps YoY, reflecting the benefits of a holistic approach focused on efficiency.

^[4] EBITDA is normalized according to the items described in the "Revenue" and "Costs" sections.

^[5] EBITDA-AL is normalized according to items described in the "From EBITDA to Net Income" section and excludes the impact of the fines related to the decommissioning of sites. For more details, access Exhibit 5 - EBITDA After Lease.

^[6] Site decommissioning is the process of deactivation of towers and transmission structures through renegotiation and/or cancellation of lease contracts with tower companies. After the acquisition of Oi Mobile, the Company is working to disconnect approximately 60% of the sites that overlap or are close to sites where TIM was already present.

2024 First Quarter Results

DEPRECIATION AND AMORTIZATION (D&A) / EBIT

The D&A line fell by 1.3% YoY in 1Q24. This result was due to (i) the reduction in depreciation of right-of-use assets from IFRS 16 leases, arising from the decommissioning of the towers; and (ii) lower software amortization amount.

Normalized EBIT grew by 36.4% YoY in 1Q24 with a margin of 18.3%, reflecting the consistent EBITDA performance.

NET FINANCIAL RESULT

* Net Financial Result normalized by the monetary adjustment on the non-recurring effect from the accounting for the closing price adjustment agreement for Oi's mobile assets (+R$27.5 million in 4Q23).

The Net Financial Result^[7] was negative by R$525 million in the quarter, down by R$302 million compared to 1Q23, mainly impacted by non-cash items: (i) negative effect in the annual comparison due to the impact of the renegotiation of tower lease agreements recorded in 1Q23; (ii) conclusion of interest capitalization for the 3.5GHz license; (iii) negative impact from the non-achievement of a new tranche of the C6 subscription bonus in 1Q24; and (iv) negative result from marking to market of derivatives in the quarter.

^[7] The Net Financial Result had a non-recurring impact of R$27.5 million in 4Q23, referring to the monetary restatement on the effect of the accounting for the adjusted closing price for Oi's mobile assets.

2024 First Quarter Results

INCOME TAX AND SOCIAL CONTRIBUTION

Income Tax and Social Contribution ("IR/CSLL"), in the Normalized^[8] view, totaled -R$69 million in 1Q24, compared to -R$156 million in 1Q23, corresponding to an effective rate of -11.7% against -26.3% in the same period of 1Q23. This improvement is related to the distribution of Interest on Equity in 1Q24, which did not occur in the same period in 2023. In 1Q23, there were also impacts in deferred taxes referring to Cozani's assets, which have also contributed to the YoY improvement.

NET INCOME

Normalized Net Income^[9] totaled R$519 million in 1Q24, a growth of 19.0% YoY, maintaining the bottom-line recovery dynamics of double-digit growth presented in the last quarters. Thus, Normalized Earnings per Share (EPS) reached R$0.21 in the quarter compared to R$0.18 in 1Q23.

CAPEX

Capex totaled R$1,355 million in 1Q24, a YoY growth of 5.1%, due to higher investments allocation in network infrastructure with the consolidation of 5G in new regions. This quarter, 5G coverage reached 100% of the neighborhoods of Belo Horizonte and Goiânia. It is worth noting that this line follows the seasonality already expected by the Company and, therefore, the guidance for Capex released by TIM for the year 2024 remains unchanged.

As a result, the Total Capex over Normalized Net Revenue ratio was 22.2% compared to 22.7% in 1Q23, down by 50 bps YoY.

^[8] The Income Tax and Social Contribution line had a non-recurring impact of R$93.8 million in 4Q23, referring to deferred and current taxes on the effect for the closing price adjustment agreement for Oi's mobile assets, -R$8.2 million in 1Q23, referring to tax credits related to the intercompany contract with Cozani, and -R$64k in 4Q23 and -R$4.2 million in 1Q23, referring to other tax effects.

^[9] Net Income is normalized according to items in the "From EBITDA to Net Income" section.

2024 First Quarter Results

CASH FLOW

Normalized EBITDA (-) Capex totaled R$1,536 million in 1Q24, up by 16.1% YoY. When returning the effects from leases, Normalized EBITDA-AL^[10] (-) Capex totaled R$843 million in the quarter, increasing by 58.6% YoY. Both results were possible due to the solid EBITDA growth, in addition to a significant reduction in the level of leases. The Normalized EBITDA-AL (-) Capex over Normalized Net Revenue ratio reached 13.8%.

* The reclassification refers to the non-recurring gain from the accounting for the closing price adjustment agreement for Oi's mobile assets, which is reallocated from the operating cash flow to the investment cash flow.

** Incentives on the payment of leases were recognized in line with the agreed contractual conditions, reducing the amount disbursed in the period (+R$33.9 million in 1Q24).

Operating Free Cash Flow ("OpFCF") was negative by R$435 million in 1Q24, worse by R$226 million in comparison to 1Q23. This result is a consequence of Reported EBITDA (-) Capex growth, and lower lease payment, offset by a negative variation of Working Capital. This negative variation is mainly explained by an increase in the balance of the Suppliers line with a higher volume of payments due to the seasonality effect of the period.

^[10] EBITDA-AL is normalized according to items in the "From EBITDA to Net Income" section and excludes the impact of the fines related to the decommissioning of sites. For more details, access Exhibit 5 - EBITDA After Lease.

2024 First Quarter Results

It is worth mentioning that the full payment of the TFF rate, which is a component of the Fistel fee, has remained suspended since 2020 to date. The total amount recognized until March 31, 2024 was R$2.7 billion, of which R$2.2 billion was principal and R$522 million was default interest. The accumulated amount of principal due in 2024 is R$2.7 billion, which will be recognized throughout the year summed to the default interest.

DEBT AND CASH

Debt Profile

2024 First Quarter Results

Total Debt (post-hedge) was R$16,314 million at the end of March 2024, down by R$2,660 million vs. 1Q23. This decrease reflects (i) the payment of a portion of the short-term financial debt; and (ii) a reduction in total lease, due to the decommissioning of sites.

The Cash and Securities balance totaled R$3,371 million at the end of March 2024, corresponding to a decrease of R$510 million against 1Q23. The year-on-year decrease can be explained due to a combination of operating cash generation, with the expansion of EBITDA, offset by the following disbursements in the period: (i) payment of financial debts (including the settlement of the debt with BNP Paribas bank in January, totaling R$518 million, and with Scotia bank in December, totaling R$979 million); (ii) payments of installments related to the acquisition of 5G frequencies (payment of two installments of the EACE, in April and October 2023, and of the 5G license corresponding to 2023, in December 2023); and (iii) payments of fines related to the decommissioning of towers.

OPERATING AND MARKETING PERFORMANCE

MOBILE SEGMENT:

At the end of 1Q24, TIM recorded 61.4 million mobile lines, declining by 0.5% YoY. This reduction reflects a combination of growth in the Postpaid base, reaching 28.1 million lines (+7.8% YoY), and a decline in the Prepaid base, reaching 33.3 million lines (-6.6% YoY). Human Postpaid (ex-M2M) reached 23.0 million lines (+6.6% YoY), reaching an M2M ("Machine-to-Machine") base of 5.1 million lines (+13.5% YoY). In net additions, TIM had 493k new lines in the Postpaid segment in 1Q24, of which 415k in Human Postpaid.

It is worth mentioning that, in March 2023, in order to adapt the distribution of customers migrated from Oi, TIM reclassified 951k customers previously allocated as Control customers to Prepaid, generating an inorganic increase in the Prepaid customer base. On the other hand, this movement had the opposite effect on the Postpaid line.

2024 First Quarter Results

FIXED SEGMENT:

TIM UltraFibra's customer base came to 806k connections in 1Q24, a YoY growth of 10.1%. The transition of customers to the fiber continues its consistent growth pace: in the period, the FTTH base expanded by 23.8% YoY.

CUSTOMER PLATFORM

The Customer Platform aims to monetize the company's customer base and increase the loyalty of these customers, through the observation of market trends and innovative partnerships. This initiative is enabled by two business models:

I.	Commercial Partnerships with:

(i)	direct remuneration for the sale of advertising and data intelligence, in which the main products used are TIM Ads and TIM Insights.

(ii)	remuneration for data products, through financial scores and standard validation/authentication products to improve the digital security of our users.

II.

Strategic Partnerships that seek to achieve the same objectives as above, in a broad way and in record time. In this model, in addition to TIM Ads and TIM Insights, we use the TIM brand to endorse the partner brand. We encourage the consumer to join the partner brand with exclusive offers. In this case, TIM's remuneration is associated to the success of this adhesion and consistent by a CAC fee and an equity stake in partner companies.

Within this strategy, some verticals were listed as great opportunities for synergy with mobile services and for having a market valuation higher than those of telecom companies. Below are details of the verticals in which we are already acting:

MOBILE ADVERTISING AND DATA MONETIZATION

In the 1^st quarter of 2024, mobile advertising and data monetization revenue grew 4 times compared to the same period in 2023, driven by new mobile advertising agreements and acceleration of scoring operations, in addition to the start of Open Gateway operations. Furthermore, to expand its inventory, TIM began testing advertising campaigns on external platforms ("offsite") using the Retail Media model. Within the scope of Open Gateway, the Mobile World Congress (MWC) reinforced the use of TIM's anti-fraud solutions by relevant customers, such as Itaú. Additionally, technical and commercial integrations with Infobip and Microsoft were announced.

2024 First Quarter Results

FINANCIAL SERVICES

In 2020, the Company concluded negotiations with Banco C6 and launched exclusive offers for TIM customers who opened accounts with the bank and used its services. In this contract, TIM receives remuneration for active accounts and the option to obtain equity participation in C6 bank as certain goals are achieved, with the number of shares received for each goal achieved varying throughout the contract.

On February 1, 2021, TIM announced that it obtained, within the scope of this partnership, the right to exercise a subscription bonus equivalent to an indirect participation of approximately 1.44% of the share capital of C6 bank, as a result of reaching, in December 2020, from the 1^st level of the agreed goals. Subsequently, the Company exercised its option to acquire and convert C6 shares, which represents approximately 1.44% of the Bank. It is important to highlight that once the option was exercised, TIM began to hold a minority position and without a position of control or significant influence in the management of C6.

Additionally, TIM holds share subscription options, which represent the Company's option to subscribe to 4.44% of C6's shares on March 31, 2024. Considering what has already been exercised, plus the options, the potential participation of TIM at C6 bank could reach approximately 5.88%, except for the ongoing arbitration dispute. More details can be found in Notes 12, 31 and 37 of the Financial Statements.

EDUCATION SERVICES

In the Education pillar, the partnership with Descomplica already surpasses 500k subscribers in various courses such as: preparation for the ENEM, free courses, undergraduate and postgraduate courses. Free courses focused on technology, such as ChatGPT and Artificial Intelligence for Non-Technicians, already reached +35k subscribers in 2024.

HEALTH SERVICES

After carrying out the operational pilots, in January 2024, the partnership was expanded to the entire national territory. Furthermore, the Cartão de Todos product was included in the portfolio, becoming the most used by TIM customers. Today there are already more than 155k customers registered in the partnership, which allows access to telemedicine, consultations, and exams with discounts and 436 private clinics spread throughout Brazil.

(In thousands of reais, unless otherwise indicated)

1.	Operations

1.1. Corporate Structure

TIM S.A. ("TIM" or "Company") is a public limited company with Registered office in the city of Rio de Janeiro, RJ, and a subsidiary of TIM Brasil Serviços e Participações S.A. ("TIM Brasil"). TIM Brasil is a subsidiary of the Telecom Italia Group that holds 66.59% of the share capital of TIM S.A on March 31, 2024 (66.59% on December 31, 2023).

The TIM group ("Group") comprises TIM and its associated company I-Systems.

The Company holds an authorization for Landline Switched Telephone Service ("STFC") in Local, National Long-Distance and International Long-Distance modes, as well as Personal Mobile Service ("SMP") and Multimedia Communication Service ("SCM"), in all Brazilian states and in the Federal District.

The Company's shares are traded on B3 - Brasil, Bolsa, Balcão ("B3"). Additionally, TIM has American Depositary Receipts (ADRs), Level II, traded on the New York Stock Exchange (NYSE) - USA. As a result, the company is subject to the rules of the Brazilian Securities and Exchange Commission ("CVM") and the Brazilian Securities and Exchange Commission ("SEC"). In order to comply with good market practices, the company adopts as a principle the simultaneous disclosure of its financial information in both markets, in reais, in Portuguese and English.

On March 31, 2024, TIM holds a 49% equity interest (49% on December 31, 2023) in the company I-Systems (associate) and held 100% on December 31, 2022 in the company Cozani RJ Infraestrutura e Rede de Telecomunicações S.A. ("Cozani") - subsidiary. Considering that the merger by TIM, through Act 3535/2023, which transferred the SMP grants associated with it, and its consequent extinction, for all purposes and effects, on April 1, 2023, consequently, TIM S.A., does not have equity interests in Cozani on March 31, 2024.

1.2. Corporate Reorganization

1.2.1. Business combination - Cozani

On April 20, 2022, TIM, together with other Buyer companies (Claro S.A. and Telefônica Brasil S.A.), after complying with the prior conditions established by CADE and ANATEL, concluded the acquisition transaction of Oi Móvel S.A. - Under Court-Ordered Reorganization ("Seller", "Assignor" or "Oi Móvel"). Due to this, TIM now holds 100% of Cozani's share capital, a company that corresponds to the part of the unit of assets, rights and obligations of Oi Móvel acquired by Company.

The total consideration recorded for the acquisition of Cozani was R$ 7,211.6 million.

TIM also paid, on April 20, 2022, on behalf of SPE Cozani, the amount of R$ 250.7 million to the Seller, as remuneration, for up to 12 months of service provision in the transition phase, recorded under "Prepaid expenses" and signed an annual contract term for the use of transport infrastructure capacity with Brasil Telecom Comunicação Multimídia S.A., involving the payment of decreasing amounts which, at present value, total approximately R$ 476 million.

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

March 31, 2024

(In thousands of reais, unless otherwise indicated)

Considering the agreed purchase amounts, we had the following balances recorded as contractual obligations on December 31, 2022:

(i)

The amount of R$ 634.3 million was 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 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 remained in an account linked to the Court until the agreement reached between the parties in October 2023. For further details, see Note 11;

(ii)	The amount of R$ 77 million recognized as contingent consideration, until there was an agreement between the parties.

On October 4, 2023, TIM S.A., through a Material Fact, communicated to its shareholders and the market in general that the Arbitration Chamber Court approved an agreement related to the Post-Closing Adjustment, celebrated, on the one hand, between TIM S.A., Telefônica Brasil S.A. and Claro S.A. and, on the other hand, Oi S.A. - Under Court-Ordered Reorganization, as a way of putting an end to the controversy and the arbitration procedure related to the Post-Closing Adjustment. The final price of the portion of UPI Ativos Móveis assigned to the Company, considering the Post-Closing Adjustment negotiated in the Agreement (except for the contract targets), was R$ 6.6 billion.

Considering the TIM Adjusted Final Price, the Company recovered a portion corresponding to half of the amount that had been deposited in court and subsequently transferred it to the Arbitration Chamber (equivalent to approximately R$ 317 million on the closing date, updated by the 100% of the CDI change until the deposit in court, plus interest and/or inflation adjustment, applicable until the date of the respective redemption), and the remaining amount was redeemed by the Seller as part of the purchase price of the UPI Ativos Móveis assigned to the Company. Mainly due to the fact that it is still a contractual debt at the date of completion of the allocation of the purchase price of the Cozani acquisition, the decrease in the consideration, corresponding to the half of the amount in court, was recorded in the income (loss) for the year on the date of approval of the agreement (October 2023), under "other operating revenues (expenses)".

On March 31, 2024 and December 31, 2023, considering the agreement signed with Oi S.A., the Company was free from any obligations mentioned in items (i) and (ii).

The goodwill paid of R$ 2,636,426 comprises the value of future economic benefits arising from synergies expected from the acquisition. The recognized goodwill has already been deducted for tax purposes since the date of the corporate acquisition of the company Cozani by TIM S.A., which took place on April 1, 2023.

Merger of Cozani

According to the Material Fact disclosed by the Company on February 27, 2023, the completion of the Merger would still depend on the conclusion of the operational procedures related to the systemic parameterization and obtaining prior consent from ANATEL, which took place when the Act 3535/2023 was published.

On March 31, 2023, the Board of Directors ("BoD") acknowledged the obtaining of said consent and verified compliance with the other conditions to grant full effectiveness to the Merger. Accordingly, the BoD declared that said Merger and the consequent extinction of Cozani became effective, for all purposes and effects, on April 1, 2023. The approved Acquisition did not give rise to a capital increase, nor issue of new shares of the Company, or changes in the Company's shareholding, therefore, there is no need to approach different topics related to the exchange of shares or right to withdraw.

The purpose of this acquisition is to streamline the corporate structure of TIM S.A., eliminate overlapping authorizations for exploring the SMP service, standardize the services provided by the Companies, and will allow the concentration of activities related to the provision of personal mobile telecommunication services in a single company, in addition to optimize operating costs and efficiently allocate investments due to the integration of acquired assets.

The changes in Cozani's equity between the date of the report (December 31, 2022) and the merger (April 1, 2023) were incorporated into the balance sheet of TIM S.A., as set forth in the protocol of merger. As a result of the merger, all operations of Cozani were transferred to TIM S.A., which succeeded it in all its assets, rights and obligations, universally and for all purposes of law.

The net assets as of December 31, 2022, is summarized below:

Assets		Liabilities
Current assets	1,376,107	Current liabilities	1,900,283
Non-current assets	3,987,996	Non-current liabilities	2,422,684

2.	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. Accordingly, relevant information of the quarterly information is being evidenced and corresponds to the information used by management when administrating.

The significant accounting policies applied in the preparation of this quarterly information are below and/or presented in its respective notes. These policies were applied consistently over the periods presented.

a. General criteria for preparation and disclosure

The individual and consolidated quarterly information was prepared considering the historical cost as value basis, except regarding the derivative financial instruments that were 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 stated 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, 2024, the Company reported a net profit of R$ 519,423. The Company's current liabilities exceeded total current assets by R$ 2,438,530, due to the acquisition of Cozani, the payment of obligations related to the 5G license, and the distribution of additional dividends of R$ 1,310,000. In the first quarter of 2024, there was a decrease in cash flow of approximately R$ 1.1 billion. The Company believes that there is a seasonal decrease in operating cash flow at the beginning of the year due to the payment of obligations and regulatory fees. On March 31, 2024, the Company's shareholders' equity is positive by R$ 25,025,216.

In connection with the preparation of this quarterly information, Company's Management made analyses which confirms that the operating cash flow in the first quarter is positive by R$ 1.6 billion; therefore, there is no evidence of uncertainties about the going concern.

The presentation of the Statement of Value Added is required by Brazilian corporate law and the accounting practices adopted in Brazil applicable to publicly-held companies. The DVA was prepared according to the criteria set forth in CPC Technical Pronouncement No. 09 - "Statement of Value Added". The IFRS do not require the presentation of this statement. Consequently, according to IFRS, this statement is presented as supplementary information, without prejudice to the set of quarterly information.

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

March 31, 2024

(In thousands of reais, unless otherwise indicated)

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

b. Functional and presentation currency

The currency of presentation of the quarterly information is the Real (R$), which is also the functional currency of the Company and its associated company.

Transactions in foreign currency are recognized by the exchange rate on the date of 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.

c. Segment information

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

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

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

d. Consolidation procedures

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

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.

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

March 31, 2024

(In thousands of reais, unless otherwise indicated)

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

e. 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 Acquirer must measure the non-controlling interest in the acquiree at the fair value or based on its interest in the net assets identified in the acquiree. 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 their fair value on the acquisition date, 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 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 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.

f. Approval of quarterly information

This individual and consolidated quarterly information was approved by the Company's Board of Directors on May 6, 2024.

g. 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, 2024 that may affect the Company somehow.

IFRS 17 - Insurance Contracts

IFRS 17 (equivalent to CPC 50 Insurance Contracts) is a new accounting standard with scope for insurance contracts, covering recognition and measurement, presentation and disclosure. IFRS 17 (CPC 50) replaces IFRS 4 - Insurance Contracts (equivalent to CPC 11). IFRS 17 (CPC 50) applies to all types of insurance contracts (such as life, non-life, direct insurance and reinsurance), regardless of the type of entities that issues them, as well as certain guarantees and financial instruments with discretionary participation characteristics; some scope exceptions will apply. The overall purpose of IFRS 17 (CPC 50) is to provide a comprehensive accounting model for insurance contracts that is more useful and consistent for insurers, covering all relevant accounting matters. IFRS 17 (CPC 50) is based on a general model, supplemented by:

·	A specific adaptation for contracts with direct participation features (variable rate approach).

·	A streamlined approach (premium allocation approach) mainly for short-term contracts.

The new standard had no impact on the Group's consolidated quarterly information.

Definition of Accounting Estimates - Amendments to IAS 8

The amendments to IAS 8 (equivalent to CPC 23 - Accounting Policies, Changes in Accounting Estimates and Errors) clarify the distinction between changes in accounting estimates, changes in accounting policies and correction of errors. They also clarify how entities use measurement techniques and inputs to develop accounting estimates.

The Company assessed that the changes in the standard did not have a significant impact on the Group's consolidated quarterly information.

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

March 31, 2024

(In thousands of reais, unless otherwise indicated)

Disclosure of Accounting Policies - Amendments to IAS 1 and IFRS Practice Statement 2

The amendments to IAS 1 (equivalent to CPC 26 (R1) - Presentation of Financial Statements) and IFRS Practice Statement 2 provide guidance and examples to help entities apply materiality judgments to accounting policy disclosures. The amendments aim to assist entities in providing more useful disclosures of accounting policies, replacing the requirement for entities to disclose their "significant" accounting policies with a requirement to disclose their "material" accounting policies. Moreover, it adds a guidance on how entities apply the concept of materiality when making decisions about disclosures of accounting policies.

The changes had an impact on the disclosure of the Group's accounting policies. The Company carried out an analysis of the financial statements, adjusting the preparation and presentation base notes, estimates and critical judgments, as well as explanatory notes when necessary. However, there was no impact on the measurement and recognition of items in the Group's quarterly information.

Deferred Tax Related to Assets and Liabilities Arising from a Single Transaction

- Amendments to IAS 12

The amendments to IAS 12 Income Taxes (equivalent to CPC 32) narrow the scope of the initial recognition exception, so that it no longer applies to transactions that generate equal taxable and deductible temporary differences, such as leases and decommissioning liabilities.

The changes had no impact on the Group's consolidated quarterly information.

International Tax Reform - Pillar Two Model Rules - Amendments to IAS 12

The amendments to IAS 12 (equivalent to CPC 32 - Income Taxes) were introduced in response to the OECD Pillar Two rules on BEPS and include the following:

·	A mandatory temporary exception to the recognition and disclosure of deferred taxes arising from jurisdictional implementation of Pillar Two model rules; and

·	Disclosure requirements for affected entities to help users of financial statements better understand an entity's exposure to Pillar Two income taxes arising from such legislation, especially before the effective date.

The mandatory temporary exception - the use of which must be disclosed - takes effect immediately. The remaining disclosure requirements apply to annual reporting periods beginning on or after January 1, 2023, but not to any interim period ending on or before December 31, 2023.

The changes had no impact on the Group's consolidated quarterly information.

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

March 31, 2024

(In thousands of reais, unless otherwise indicated)

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, 2024.

Amendments to IFRS 16: Lease liabilities in a Sale and Leaseback

In September 2022, the IASB issued amendments to IFRS 16 (equivalent to CPC 06 - Leases) to specify the requirements that a seller-lessee uses in measuring the lease liability arising from a sale and leaseback transaction, aiming to ensure that the seller-lessee does not recognize any gain or loss that relates to the right of use that it maintains.

The amendments are effective for annual financial statement periods beginning on or after January 1, 2024 and must be applied retrospectively to sale and leaseback transactions entered into after the initial application date of IFRS 16 (CPC 06). Early adoption is allowed and this fact must be disclosed.

The Group does not expect a significant impact on the quarterly information.

Amendments to IAS 1: Classification of Liabilities as Current or Non-current

In January 2020 and October 2022, the IASB issued amendments to Paragraphs 69 to 76 of IAS 1 (equivalent to CPC 26 (R1) - Presentation of Financial Statements) to specify the requirements for classifying liabilities as current or non-current. The amendments clarify the following:

·	What is meant by the right to postpone settlement.

·	That the right to postpone must exist at the end of the financial reporting period.

·	That the classification is not affected by the likelihood that an entity will exercise its right of postponement.

·	That only if a derivative embedded in a convertible liability is itself an equity instrument would the terms of a liability not affect its classification.

Moreover, a disclosure requirement was introduced when a liability arising from a loan agreement is classified as non-current and the entity's right to defer settlement depends on the fulfillment of future covenants within twelve months.

The amendments apply to annual financial statements periods starting on or after January 1, 2024 and must be applied retrospectively.

The Group has not identified changes that have a significant impact on the financial statements.

Supplier financing agreements - Amendments to IAS 7 and IFRS 7

In May 2023, the IASB issued amendments to IAS 7 (equivalent to CPC 03 (R2) - Statement of Cash Flows) and IFRS 7 (equivalent to CPC 40 (R1) - Financial Instruments: Disclosures) to clarify the characteristics of supplier financing arrangements and require additional disclosures of those arrangements. The disclosure requirements in the amendments are intended to help users of financial statements understand the effects of supplier financing arrangements on an entity's obligations, cash flows and liquidity risk exposure.

The amendments are effective for annual financial statement periods starting on or after January 01, 2024. Early adoption is permitted, but must be disclosed.

The Company is assessing the impacts to ensure that all information complies with the standard.

h. Restatement of statements of cash flows

As part of our ongoing process to improve the overall quality of the Company's quarterly information and to promote greater comparability and consistency with other companies in the sector, we have changed our accounting policy related to the presentation of purchases and sales of marketable securities in the statements of cash flow. Previously, the Company reported these transactions as an investment activity on a net basis (R$ 1,865 million as of March 31, 2023), under IAS 7, paragraph 22(b) and 23A(b). In connection with the new accounting policy, the Company reported these transactions as an investment activity on a gross basis under paragraph 21 of IAS 7/CPC 03. The Company also changed the presentation of interest revenue from marketable securities, which were previously presented as an investment activity (R$ 16 million on March 31, 2023) to an operational activity, under IAS 7/CPC 03, paragraph 33. The Company retrospectively applied the change in accounting policy under IAS 8/CPC 23, paragraph 19(b).

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

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

By definition, resulting accounting estimates are seldom equal to the respective taxable income. 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)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 8.c).

(In thousands of reais, unless otherwise indicated)

(b)Provision for legal and tax administrative proceedings

The legal and tax administrative proceedings are analyzed by the Management along with its legal advisors (internal and external). The Company considers factors in its analysis such as hierarchy of laws, precedents available, recent court judgments, their relevance in the legal system and payment history. These assessments involve Management's judgment (note 24).

(c)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 37).

(d)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 28).

(e)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.

6.	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 decrease 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, 2024 and December 31, 2023.

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, 2023).

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. At that time, TIM recorded its best estimate, in the amount of R$ 535 million (principal). Over the years, there has been recognition of the inflation adjustment in the amounts of R$ 11 million in 2021, R$ 61 million in 2022, and R$ 41 million in 2023 and R$ 5 million in 2024.

In the third quarter of 2023, TIM's lawsuit received a favorable final and unappealable decision and in September the Company obtained credit approval from the Brazilian Federal Revenue Service. At this time, the tax credits recognized in assets were segregated, as the tax credit is made up of corporate income tax (IRPJ) and social contribution (CSLL) amounts overpaid and subject to offset against other federal debts and deferred tax assets backed by tax loss balances and negative basis of CSLL offset over the years considering a taxable income, increased by the SELIC update on undue debts. By reducing taxable income, it was possible to partially recover the tax loss and CSLL negative basis that were offset, as the legislation provides for the offsetting of up to 30% of the taxable income for the period.

Thus, the company carried out the reclassification between asset accounts (Recoverable income tax and social contribution x Deferred income tax and social contribution) amounting R$ 156 million, recognizing deferred taxes on tax losses and negative CSLL basis in the amounts of R$ 114 million and R$ 42 million, respectively. The amount of R$ 470 million that was reclassified from non-current to current remained in recoverable IRPJ and CSLL accounts. A write-off of R$ 13 million was made in the third quarter of 2023 to adjust the amount recorded in the third quarter of 2021. During the third quarter of 2023, the Company started using such tax credits to offset current PIS and COFINS debits and other federal taxes. The Company used the amount of R$ 151 million in 2023 and R$ 126 million in 2024.

8.b	Income tax and social contribution payable

Current income tax and social contribution charges are calculated on the basis of the tax laws enacted, or substantially enacted, up to the balance sheet date.

The legislation allows companies to opt for quarterly or monthly payment of income tax and social contribution. In 2024, the Company has chosen to make the quarterly payment of income tax and social contribution.

8.c	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 assets and liabilities are presented at net value in balance sheet when there is the legal right and the intention of offsetting them upon calculation of current taxes, in general related to the same legal entity and the same tax authority. Accordingly, deferred tax assets and liabilities in different entities are in general presented separately, and not at net balance.

On March 31, 2024 and December 31, 2023, 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.

Such tax adjustment generated a deferred liability of R$ 925 million until March 31, 2024 (R$ 891 million up to December 31, 2023) and applied as of January 1, 2020.

(iv) Refers to deferred charges on the adjustment at 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).

(i) Cozani's results show the changes from the acquisition date. The date of acquisition and transfer of control was April 20, 2022 and the results of the subsidiary Cozani were consolidated on April 30, 2022, as the financial information available is closest to the date of transfer of control. Management concludes that the impacts of results generated between the date of acquisition and the beginning of consolidation are immaterial. On April 1, 2023, Cozani was incorporated by TIM S.A. Therefore, there is no longer a company controlled by TIM S.A.

Cozani's shareholders' equity as of April 30, 2022 was adjusted to comply with the Company's accounting practices, reflecting a decrease of approximately R$ 1,641 million, mainly related to the impairment of tangible assets, recording of onerous capacity contract and deferred taxes.

15.	Property, plant and equipment

Property, plant and equipment are measured at acquisition and/or construction cost, less accumulated depreciation and impairment losses (the latter only if applicable). Depreciation is calculated based on the straight-line method over terms that consider the expected useful lives of the assets and their residual values. The amounts of property, plant and equipment recorded on Cozani's acquisition were adjusted on December 31, 2022 to its recoverable amounts and after the merger are recorded at TIM S.A. On March 31, 2024 and December 31, 2023, the Company has no other indication of impairment in its property, plant and equipment.

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

(In thousands of reais, unless otherwise indicated)

In 2023, pursuant to IAS 16 / CPC 27, approved by a CVM Deliberation 73, the Company assessed the useful life estimates for their property, plant and equipment, concluding that there were no significant changes or alterations to the circumstances on which the estimates were based that would justify changes to the useful lives currently in use.

16.	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 had 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 between 2021 and 2023. As of the second quarter of 2023, the capitalization of interest and charges on this asset ended. 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 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.

Intangible assets with undefined useful lives are not amortized but tested for impairment on an annual basis, individually or at cash generating unit level.

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

The Company has the following goodwill, based on the expected future profitability on March 31, 2024 and December 31, 2023.

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, 2024 and December 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.

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, 2024 and December 31, 2023.

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

March 31, 2024

(In thousands of reais, unless otherwise indicated)

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.

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 TIM S.A., Tim Group's operating company in Brazil and that in 2023 merged Cozani's balances, acquired in 2022. This methodology is aligned with the company's strategic direction. It is worth highlighting that the group's results are mainly represented by TIM S.A., but since the merger of Cozani occurred on April 1, 2023, these results impacted the consolidated TIM S.A. until March 31, 2023.

On December 31, 2023, 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 1.

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

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.

On December 31, 2023, 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. 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.

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

March 31, 2024

(In thousands of reais, unless otherwise indicated)

On March 31, 2024, the Company carried out the analysis of all tangible, intangible assets and investments and did not identify any impairment indicators.

(e) Infrastructure right-of-use - 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).

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

(In thousands of reais, unless otherwise indicated)

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. In the second quarter of 2023, the asset was considered available for use by the Company, ceasing such capitalization. Thus, the transfer of goods in progress to the line of authorizations in service was carried out. The Company recorded R$ 95 million in intangible assets referring to interest calculated based on the Selic rate until 2023, 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.

The total effect on the Company's intangible assets on March 31, 2024 referring to 5G radio frequencies and related obligations was R$ 3,930 million (R$ 3,930 million in 2023) and there are no more balances of assets in progress relating to 5G licenses since 2023.

17.

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.

In these agreements, the company and Telefónica Brasil S.A. share investments made in the Northern Region of Brazil. The company has monthly amounts receivable from Telefónica Brasil S.A. for a period of 20 years, adjusted annually by the IPC-A. The discount rate used to calculate the present value of the installments due is 12.56% per annum, considering the date of signing the agreement.

(ii) Subleases - Stores - IFRS 16

The Company, due to sublease agreements for third parties in some of its stores, recognized the present value of short and long term receivables, which are equal in value and term to the liability cash flows of the contracts called "resale stores". The impact on lease liabilities is reflected in the group "Leases - Shops & Kiosks and Real Estate".

The amount of the Company's subleasing revenue in the period ended March 31, 2024, is R$ 16,264 (R$ 14,640 in the same period of 2023).

i) LT Amazonas

The Company executed agreements for the right to use the infrastructure of companies that operate electric power transmission lines in Northern Brazil ("LT Amazonas"). The terms of these agreements are for 20 years, counted from the date on which the assets are ready to operate. The contracts provide for monthly payments to the electric power transmission companies, restated annually at the IPCA.

The discount rate used to calculate the present value of the installments due is 14.44% per annum, considering the signing date of agreements with transmission companies.

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 thousands of reais, unless otherwise indicated)

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 23).

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, 2024 for the above contracts was estimated month-to-month, based on the average incremental rate of the Company's loans, namely 13.65% (14.29% in 2023).

The lease amounts considered low-value or short-term (less than 12 months) were recognized as rental expenses and totaled R$ 7,383 on March 31, 2024 (R$ 8,377 in the same period of 2023).

18.	Other amounts recoverable

These refer to Fistel credit amounts arising from the decrease of the customer 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 decrease of the TFF contribution (operating supervision fee) due to Anatel.

On March 31, 2024, this credit is R$ 68,892 (R$ 80,963 on December 31, 2023).

19.

Suppliers

Accounts payable to suppliers are obligations payable for goods or services that were acquired in the usual course of business. They are initially recognized at fair value and, subsequently, measured at 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.

With respect to proceeds contracted with The Bank of Nova Scotia, Debentures, 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 operations on March 31, 2024, is detailed in the table below:

On June 18, 2020, ANATEL's Board of Directors unanimously approved TIM's conduct adjustment term (TAC) 001/2020, which had been negotiated since 2014 with the regulator.

On June 19, 2020 the Board of Directors of the company approved the said TAC after final deliberation of the regulator and the signing of the term took place on June 25 of the same year. The agreement covers sanctions totaling approximately R$ 639 million (updated at the time), filed as a result of commitments represented in improvement actions related to the macro-topics "Quality", "Access Expansion", "Rights and Guarantees of Users" and "Inspection".

The Term includes actions to improve three pillars of action-customer experience, quality and infrastructure - through initiatives associated with improvements in the licensing process of stations, efficient use of numbering resources, evolution of digital service channels, decrease of Complaint Rates, repair of users and 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 less than three years - more than 99% of the municipalities were served in the first two years and with the Company guaranteeing the sharing regime with the other operators. The service for 350 municipalities was certified by Anatel in June 2023.

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. The following commitments were certified by Anatel: Numbering; Impediment; Internal controls; LTE 700 MHz; New 4G; Backhaul; Personal assistance; Digital relationship; Additional; and Collaborative Portal.

In October 2022, TIM and Anatel signed the Amendment to renegotiate the commitment related to Quality Indicators. Thus, the Perceived Quality Index (IQP) started to be adopted to replace the General Quality Index (IGQ) for Years 3 and 4 of the TAC.

In June 2023, TIM concluded the 3^rd 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. Regarding the Additional Commitments, as aforementioned, Anatel has already issued a statement of fulfillment of the obligation relating to the third year of the TAC, guaranteeing the general statement of fulfillment of the obligation for the implementation of SMP with 4G or later technology in 350 (three hundred and fifty) municipalities under the terms agreed in the TAC. In December 2023, the following Commitments were attested: Numbering; Impediment; Repair Plan; Internal controls; LTE 700 MHz; New 4G; Backhaul; Digital relationship.

In July 2023, TIM started the fourth and final year of TAC. The Company will continue fully implementing the internal monitoring mechanisms on the evolution of the schedules by the Governance Office in Management and Board of Directors.

The Company has met the TAC implementation schedule and has reported its understanding to Anatel in cases where the Agency indicates signs of non-compliance in the Procedures for Assessing the Non-Compliance with a Schedule Item (PADIC) that may be implemented.

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.

On March 31, 2024, the accumulated amount of benefits enjoyed by the Company amounts to R$ 2,362,239 (R$ 2,362,239 on December 31, 2023).

As provided in the company's bylaws, unclaimed dividends within 3 years will revert to the company.

As of December 31, 2023, dividends and Interest on Shareholders' Equity were calculated as follows:

	2023

Net profit for the year	2,837,422
(-) Non-distributable tax incentives	(237,828)
(-) Constitution of legal reserve	(129,979)

28.	Net revenue

Revenues 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.

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 (loss) 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, 2024 is R$ 31,186 (R$ 31,581 on March 31, 2023).

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 10) 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.

37.	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 to which the Company is exposed are:

(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 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, 2024 and December 31, 2023, 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 refer 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, 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, 2024 and December 31, 2023, the Company maintains its financial resources applied to Interbank Certificates of Deposit (CDI), which substantially reduces this risk.

(In thousands of reais, unless otherwise indicated)

(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, 2024 and December 31, 2023 or revenues from services rendered during the periods ended March 31, 2024 and 2023.

(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 March 31, 2024 and 2023. There are no customers who contributed more than 10% of the net receivables from the sale of goods as of March 31, 2024 and December 31, 2023.

(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 interest earning bank deposits 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 consideration the investment, debt financing plans, compliance with covenants, attainment of the internal goals and if applicable, external or legal regulatory 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.

As required by IFRS 9 / CPC 48, the financial instrument must be valued at its fair value that on March 31, 2024 and December 31, 2023 corresponds to R$ 502 million. There was no change in the period, as the Company did not exercise the subscription right relating to contract targets.

The impact of the mark-to-market is calculated by 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 subsequently revaluated and possible changes recorded in the Company's financial income (loss) for the year, considering the arbitration risks disclosed in Note 28.

The fair value of financial instruments traded in active markets is based on quoted market prices at 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 the 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 (for example, over-the-counter derivatives) is determined based on valuation techniques. These valuation techniques maximize the use of the 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 from financial institutions or brokerage firms for similar instruments.

·	The fair value of swaps of interest rate is calculated at the present value of future cash flows estimated based on 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.

The regular purchases and sales of financial assets are recognized on the trading date, which is the date when the Company commits 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. To cover interest rates, it is up to the Company to elect or not to contract a hedging mechanism, as provided for in the internal policies.

On March 31, 2024, there are no margins or guarantees applied to transactions with derivative financial instruments of the Company.

Based on mandatory market developments, we changed the index of our debt with KFW/Finninvera from Libor to SOFR.

Likewise, for maintaining the hedge, we migrated the swap transaction with Bank of America, which until then was indexed to Libor and became indexed to SOFR as of January 2024. Transition without any cash effect and with the same cost as a percentage of the original CDI.

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

The operations with derivative financial instruments contracted by the Company and in force on March 31, 2024 and December 31, 2023 are shown in the following table:

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), SOFR 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, SOFR 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 (i)	Fair value in USD, EUR, BRL and IPCA (ii)	A) ∆ Accumulated variation in debt	Fair value of the long position of the swap (+)	Fair value of the short position of the swap (-)	Swap result	B) ∆ Accumulated variation in swap	C) Final result (B-A)

(i) Scenarios sensitized with the following increase in rates: probable scenario without increase; possible scenario with 25% increase; and remote scenario with 50% increase.

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, 2024 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.
