2024 THIRD QUARTER RESULTS

FINANCIAL PERFORMANCE

OPERATING REVENUE

REVENUE GROWING AT A HEALTHY PACE TO MEET 2024 GOALS

* Net Revenue normalized by the temporary effect from the inefficiency of PIS/COFINS arising from a contract signed between TIM S.A and Cozani (+R$41.0 million in 1Q23). The merger of Cozani into TIM S.A. became effective on April 01, 2023.

In 3Q24, Normalized Net Revenue grew by 6.0% YoY, totaling R$6,419 million. This result was mainly due to the expansion in Mobile Service Revenue, which increased by 6.3% YoY, leveraged by Postpaid, which grew by 8.3% YoY in 3Q24. In 9M24, revenue dynamics were similar, with Normalized Net Revenue increasing by 6.9% YoY and Mobile Service Revenue growing 7.0% YoY.

2024 THIRD QUARTER RESULTS

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

Normalized Mobile Service Revenue (“MSR”) amounted to R$5,898 million in 3Q24, corresponding to a 6.3% YoY expansion, benefited mainly by the positive performance in Postpaid which reflects a smarter management of the customer base amid a less pronounced annual price adjustment dynamic in 2024 compared to 2023. The following factors stand out for this performance: (i) the migration of customers to higher value-added plans (Prepaid-Postpaid and Pospaid-Postpaid); and (ii) efforts to reduce disconnection rates (Postpaid Churn ex-M2M of -0.7% in 3Q24). Normalized Mobile ARPU (average monthly revenue per user) reached R$31.7, representing an increase of 4.8% YoY. In 9M24, Normalized MSR grew by 7.0% YoY.

In 3Q24, Client Generated Revenue (MSR excluding interconnection, customer platform and other revenues) reached R$5,477 million, up by 6.5% YoY. This performance was explained by the recurring growth in revenue generated by TIM Customers and an increase in revenue from non-TIM Customers, benefited by the performance of TIM Viagem packages after the reformulation of the international roaming portfolio in September 2023. In 9M24, Client Generated Revenue grew by 7.5% YoY.

In 3Q24, Interconnection (ITX) Revenue dropped by 21.9% YoY, which was already expected and in line with the reduction in MTR (“Mobile Termination Rate”) rate and lower incoming traffic. In 9M24, this line fell by 18.6% YoY.

Customer Platform Revenue was R$40 million in 3Q24, compared to R$54 million in 3Q23, falling by 26.7% YoY. The reduction is explained by the Company's operating model which encompasses an activation fee-based model for some segments and a revenue share model for others. On the positive side, the Mobile Advertising and Data Monetization initiatives also stood out, growing robust double digits YoY for another quarter. In 9M24, the line reached R$101 million, down by 17.0% for the same reasons.

The Other Normalized^[2] Revenue line increased by 21.7% YoY in 3Q24, mainly due to higher revenues from IoT projects for the agribusiness. In 9M24, this line increased by 13.0% YoY.

Below is the performance breakdown of each mobile customer profile:

(i)

Postpaid Revenue increased by 8.3% YoY in 3Q24, with Postpaid ARPU reaching R$43.3 in the quarter (-0.9% YoY) and Postpaid ex-M2M ARPU reaching R$53.2 (+0.7% YoY). This performance is explained by: (i) the annual price adjustments for part of the Postpaid customer base, but at a lower percentage than in 2023; (ii) efforts to migrate customers to higher-value plans; and (iii) the Company’s success in reducing churn rates .. In 9M24, Postpaid Revenue increased by 8.6% YoY.

^[2] The Other Revenues line had a non-recurring impact of R$41.0 million in 1Q23, referring to the temporary effect of the inefficiency of PIS/COFINS, arising from a contract signed between TIM S.A and Cozani, which was extinguished with the merger Cozani.

2024 THIRD QUARTER RESULTS

(ii)

Prepaid Revenue declined by 5.1% YoY in 3Q24, with Prepaid ARPU reaching R$14.9 (-0.3% YoY). Excluding Interconnection Revenue, Prepaid Revenue would have declined by 4.3% YoY. This performance in Prepaid continues to be impacted by: (i) the consecutive increases in customer migration from Prepaid to Postpaid; and (ii) lower recharging recurrences in certain customer groups. In 9M24, Prepaid Revenue fell by 2.1% YoY.

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

In 3Q24, Fixed Service Revenue amounted to R$333 million, up by 2.6% YoY. In 9M24, Fixed Service Revenue grew by 4.2% YoY.

TIM Ultrafibra, the main line for the fixed segment, grew by 6.0% YoY in 3Q24, with ARPU of R$99.0 (+5.9% YoY). This performance reflects the Company's strategy to carry out a more selective expansion of TIM Ultrafibra, which arrived in the state of Rio Grande do Sul, covering 28 new municipalities in 3Q24. It is worth mentioning that FTTH (Fiber-to-the-Home) already accounts for over 94% of our total broadband customer base. In 9M24, TIM Ultrafibra Revenue increased by 7.7% YoY.

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

Product Revenue expanded 3.5% in 3Q24 and 9.6% YoY in 9M24. In 9M24 the performance is explained by:(i) an increase in the volume of device sales; (ii) the sale of accessories (cases, screen protectors, etc.) for phones; (iii) an increase in sales of other equipment such as wearables and modules related to "B2B IoT," reinforcing the Company's portfolio diversification strategy.

2024 THIRD QUARTER RESULTS

OPERATING COSTS AND EXPENSES

EFFICIENT MANAGEMENT OF COSTS AND EXPENSES THAT CONTINUE TO GROW PRACTICALLY IN LINE WITH INFLATION IN THE PERIOD

* Operating Costs normalized by: expenses with consulting within the scope of the acquisition project of Oi Móvel and customer migration (+R$2.1 million in 3Q23, +R$16.3 million in 2Q23 and +R$12.5 million in 1Q23), PIS/COFINS credits generated in the intercompany contract with Cozani (-R$17.7 million in 1Q23), expenses with FUST/FUNTEL related to the intercompany contract with Cozani (+R$886k in 1Q23), expenses with specialized legal and administrative services (+R$1.1 million in 2Q23) and payroll expenses related to the acquisition of Oi Mobile (+R$8.4 million in 3Q23).

Normalized Operating Costs and Expenses was R$3,183 million in 3Q24, up by 4.5% YoY, practically in line with inflation in the period (in September, the accumulated 12-month IPCA was 4.42%), reflecting the Company’s efficient cost management. This line was negatively affected by these key items: (i) higher interconnection expenses, related to international roaming services and costs related to network; and (ii) higher advertising expenses due to the campaigns for TIM Pré XIP and Rock in Rio. In 9M23, Normalized Operating Costs and Expenses grew 5.2% YoY.

Breakdown of Normalized Costs and Expenses Performance:

Normalized Personnel costs^[3] grew by 7.4% YoY in 3Q24, impacted by annual salary adjustments and improved benefits, which were partially offset by the drop in expenses related to long-term incentives. In 9M24, this line increased by 8.3%, also due to the salary increases and improved benefits, in addition to provisions for expenses related to employee profit-sharing in the Company's results.

The Selling and Marketing line increased by 4.0% YoY in 3Q24, mainly due to higher advertising expenses related to the launch of TIM Pré XIP and the Rock in Rio campaigns. In 9M24, this cost line increased slightly, by 1.8% YoY, reflecting the increases in advertising expenses, as previously mentioned, and was partially offset by the recognition of Fistel credits, which had a positive effect in the 9M23 results.

^[3] In 3Q23, the Personnel costs line had a non-recurring impact of R$8.4 million referring to payroll expenses related to the acquisition of Oi's mobile assets.

2024 THIRD QUARTER RESULTS

The Normalized Network and Interconnection group^[4] increased by 9.2% YoY in 3Q24, due to: (i) higher expenses for international roaming services, still reflecting the increase in traffic volume after the strategy to reformulate the Postpaid portfolio in September 2023; and (ii) higher spending related to network infrastructure. These amounts were partially offset by lower expenses with content providers and leased lines. In 9M24, this line grew by 10.8% YoY.

Normalized General and Administrative Expenses (G&A)^[5] fell by 0.7% YoY, totaling R$214 million in 3Q24, mainly due to customer billing digitalization initiatives. This reduction was partially offset by higher software maintenance expenses related to the cloud migration project and third-party services. In 9M24, this line fell by 2.8% for the same reasons.

The Cost of Goods Sold (COGS) line declined by 2.5% YoY in 3Q24,due to more efficient inventory management. In 9M24, COGS grew by 5.6%, in line with the same growth levels for sales of devices, mainly in 2Q24.

The Bad Debt line grew by 7.6% YoY in 3Q24, due to the growth in the Postpaid revenue base. Despite this increase, the Bad Debt over Gross Revenue ratio remains healthy, corresponding to 1.9% (compared to 1.9% in 3Q23). In 9M24, this expense line increased by 9.6% YoY.

Other Normalized^[6] Operating Expenses (Income) fell by 24.6% YoY in 3Q24, mainly due to lower provisions for tax contingencies and lower expenses with civil lawsuits. In 9M24, this cost line fell by 19.9% YoY, for the same reasons.

^[4] The Network and Interconnection line had a non-recurring impact of R$2.1 million in 3Q23, R$16.3 million in 2Q23 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.

^[5] The G&A expenses line was impacted by non-recurring items, in the amount of R$1.1 million in 3Q23 and R$1.1 million in 2Q23, referring to expenses with specialized legal and administrative services for the acquisition of Oi’s assets.

^[6] The Other Operating Expenses (Revenues) line had a non-recurring impact of R$886k in 1Q23, referring to expenses with FUST/FUNTEL.

2024 THIRD QUARTER RESULTS

FROM EBITDA TO NET INCOME

EBITDA AND MARGINS CONTINUE TO EVOLVE AND SUSTAIN THE NET PROFIT EXPANSION

* Normalized EBITDA according to the items described in the Revenue section (+R$41.0 million in 1Q23) and Costs (+R$11.6 million in 3Q23, +R$17.4 million in 2Q23 and -R$4.4 million in 1Q23). Normalized Net Income according to the items described in the Revenue and Costs sections, as described previously, and by non-recurring items in Income Tax and Social Contribution: tax credits related to the intercompany contract with Cozani (-R$8.2 million in 1Q23) and other tax effects (-R$3.9 million in 3Q23, -R$5.9 million in 2Q23, -R$4.2 million in 1Q23).

EBITDA^[7] (Earnings Before Interest, Taxes, Depreciation, Amortization and Equity in Earnings)

Normalized EBITDA reached R$3,236 million in 3Q24, up by 7.5% YoY, as a result of the positive Service Revenue performance and ongoing cost control initiatives. This improvement allowed the Normalized EBITDA Margin to reach higher levels, of 50.4% in the quarter, expanding by 0.7 p.p. YoY. In 9M24, Normalized EBITDA grew by 8.7% YoY, reaching a Margin of 49.3% (+0.8 p.p. YoY).

^[7] EBITDA is normalized according to the items described in the “Revenue” and “Costs” sections.

2024 THIRD QUARTER RESULTS

Considering the effects of the leases on EBITDA, the Normalized EBITDA-AL (“After Lease”)^[8] (excluding impacts from fines related to the site decommissioning process^[9]) grew by 8.8% YoY in 3Q24, totaling R$2,504 million, with a margin of 39.0%, an increase of 1.0 p.p. YoY. This growth reflects the Company's consistent operational performance, despite the increase in recurring leases QoQ, which were impacted by: (i) lower levels of incentives arising from contractual negotiations; and (ii) an expected increase in new towers and the beginning of solar plants rental. In 9M24, Normalized EBITDA-AL grew by 13.9% YoY, totaling R$7,162 million.

^[8] 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 process of the sites. For additional details, access Exhibit 5 – EBITDA After Lease.

^[9] 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 THIRD QUARTER RESULTS

DEPRECIATION AND AMORTIZATION (D&A) / EBIT

The D&A line increased by 2.0% YoY in 3Q24, mainly driven by the combination of the following: (i) a higher depreciation for the network infrastructure and telecommunications equipment arising from investments made during the year to expand 5G; (ii) partially offset by a lower depreciation on IFRS 16 lease rights due to the sites decommissioning process. In 9M24, the D&A line fell by 1.2% YoY.

Normalized EBIT increased by 16.3% YoY in 3Q24, with a margin of 22.3%, reflecting the strong EBITDA growth in the period. In 9M24, Normalized EBIT increased by 26.3% YoY, achieving a margin of 20.8%.

NET FINANCIAL RESULT

In 3Q24, the Net Financial Result was negative by R$459 million, worsening by R$53 million from 3Q23. This result can be explained by factors that positively affect results in 3Q23, such as: (i) a negative impact from the annual comparison for interest on leases due to a more significant reduction in 3Q23, when lease contracts were renegotiated, in line with the decommissioning process for sites; (ii) lower monetary update on contingencies contributing to the performance of the other line in non-cash items; and (iii) a negative impact from non-cash items in mark-to-market for C6 due to the recognition, in 3Q23, of the achievement of a new contractual tranche of the bank’s subscription bonus. In 9M24, this line worsened by 35.9% YoY, mainly impacted by non-cash items: (i) a lower mark-to-market of derivatives; (ii) termination of capitalization on license interest; and (iii) a positive effect, in 1Q23, related to the renegotiation of lease tower contracts.

2024 THIRD QUARTER RESULTS

INCOME TAX AND SOCIAL CONTRIBUTION

Income Tax and Social Contribution (IR/CSLL), in the Normalized^[10] view, was -R$167 million in 3Q24, compared to -R$100 million in 3Q23, corresponding to an effective rate of -17.2% against -12.2% in 3Q23. This variation reflects the higher amounts of Interest on Capital declared in 3Q23, totaling R$425 million, compared to R$300 million in 3Q24. In 9M24, the Income Tax and Social Contribution line was -R$378 million, reaching an effective rate of -15.2%.

NET INCOME

Normalized Net Income^[11] reached R$805 million in 3Q24 (+11.2% YoY), maintaining a double-digit annual growth for the 6^th consecutive quarter and reaching the highest net income level recorded by the Company in a third quarter. As a result, Normalized Earnings per Share (EPS) for the quarter reached R$0.33 vs. R$0.30 in 3Q23. In 9M24, Normalized Net Income expanded by 17.1% YoY, with an EPS of R$0.87.

INVESTMENTS, CASH FLOW AND DEBT

THE EFFICIENT ALLOCATION OF INVESTMENTS ENABLES A HEALTHY CASH GENERATION AIMING AT DELIVERING THE GUIDANCE TARGETS

CAPEX

^[10] The Income Tax and Social Contribution line had a non-recurring impact of -R$ 8.2 million in 1Q23, related to tax credits with the Cozani intercompany contract, and of -R$3.9 million in 3Q23, -R$5.9 million in 2Q23 and -R$4.2 million in 1Q23, related to other tax effects.

^[11] Net Income is normalized according to items in the “From EBITDA to Net Income” section.

2024 THIRD QUARTER RESULTS

Capex amounted to R$896 million in 3Q24, a decrease of 10.2% YoY due to higher investments in network and IT infrastructure carried out by the Company in the same period of the previous year. Nevertheless, TIM continues to invest in the expansion of its 5G network, adding coverage to 142 new municipalities in the third quarter of 2024. The Total Capex over Normalized Net Revenue ratio reached 14.0% in 3Q24, compared to 16.5% in 3Q23 (falling by 2.5 p.p.). In 9M24, Capex fell by 1.1% YoY, reaching R$3,176 million. It is worth noting that the Company’s guidance for 2024 remains unchanged, with Capex guidance already disclosed between R$4.4 billion and R$4.6 billion.

CASH FLOW

Normalized EBITDA (-) Capex amounted to R$2,340 million in 3Q24, up by 16.3% YoY. Returning the effects from leases, Normalized EBITDA-AL^[12] (-) Capex reached R$1,608 million, maintaining solid a double-digit growth pace (+23.4% YoY). Both results were achieved due to the consistent EBITDA growth and lower Capex levels. The Normalized EBITDA-AL (-) Capex over Normalized Net Revenue ratio reached 25.0% in the quarter. In 9M24, Normalized EBITDA (-) Capex grew by 14.6% YoY and Normalized EBITDA-AL (-) Capex increased 29.7% YoY (representing 21.2% of Normalized Net Revenue).

* The Company recognized incentives on lease payments received in line with the agreed contractual conditions, reducing the amount disbursed in the period (+R$14.1 million in 3Q24, +R$31.6 million in 3Q24, +R$31.6 million in 2Q24 and +R$33.9 million in 1Q24).

^[12] 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 process of the sites. For additional details, access Exhibit 5 – EBITDA After Lease.

2024 THIRD QUARTER RESULTS

Operating Free Cash Flow (“OpFCF”) totaled R$1,743 million in 3Q24, increasing by R$288 million (+19.8% YoY) from 3Q23, primarily due to the improvement in Reported EBITDA (-) Capex, which increased by 16.9% YoY. The variation in working capital returned to a positive level, as expected by the Company, but, despite that, it declined by R$75 million from 3Q23. This performance is explained by: (i) the “Trade Accounts Receivable” line, which was impacted by new revenue lines; (ii) the “Suppliers” line, which was impacted by the mix between operating costs and Capex; (iii) partially offset by the “Other Liabilities” line, which has been reducing since last year due to payments to third parties that carried out the shutdown of towers. In 9M24, OpFCF grew by 27.2% YoY, due to the improvement in operating performance and reduction in lease payments.

It is worth highlighting that the full payment of the TFF (Operating Inspection Fee), which makes up the Fistel rate, has been suspended since 2020. The total amount registered, until September 30, 2024, was R$3.2 billion, of which R$2.5 billion was principal and R$659 million in late interest payments.

DEBT AND CASH

Debt Profile

2024 THIRD QUARTER RESULTS

Total Debt (post-hedge) amounted to R$16,285 million at the end of September 2024, down by R$1,976 million over 3Q23. This decrease reflects mainly: (i) the settlement of a portion of the short-term financial debt; and in a lower proportion (ii) the reduction in total leases, due to the decommissioning of sites.

The Cash and Securities balance totaled R$4,332 million at the end of September 2024, representing a decrease of 2.6% YoY. The disbursements made in the last 12 months, mainly those related to the settlement of a part of the short-term financial debt, were partially offset by the Company's solid operational performance in the period.

OPERATIONAL PERFORMANCE

MOBILE SEGMENT:

In 3Q24, TIM recorded 62.1 million mobile lines, representing a net addition of 895k new lines in the last 12 months and 163k new lines in the quarter. This result was driven by the Postpaid segment, which grew 9.2% YoY, totaling 29.7 million customers, an increase of more than 2.5 million customers in the last 12 months and 709k in 3Q24. Of these, 23.9 million were in Human Postpaid (+7.6% YoY). The Prepaid segment totaled 32.5 million customers, down by 4.7% YoY, impacted by the migration of customers from the Prepaid to Postpaid.

FIXED SEGMENT:

TIM Ultrafibra’s customer base reached 793k connections in 3Q24, practically flat in the annual comparison (+0.3% YoY). This performance reflects the Company’s strategy of being more selective in its geographic expansion. Even so, the FTTH base, which represents the main portion of its broadband services, added 744k new customers in 3Q24, an increase of 7.5% YoY.

2024 THIRD QUARTER RESULTS

CUSTOMER PLATFORM

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

Commercial Partnerships with:

(i)

direct remuneration for the sale of advertising and data intelligence where the main products are TIM Ads and TIM Insights. We maintained a YoY growth in 3Q24, driven by recurring campaigns from relevant advertisers and the entry of new brands. We also launched the initial campaigns for external inventories, expanding our operations in the Retail Media model;

(ii)

remuneration for data products, through financial scores and standardized validation/authentication products to improve the digital security of our users. In 3Q24, we maintained a recurring growth in profitability of financial scoring solutions and Open Gateway products. Additionally, we performed over 78 million queries in the quarter, demonstrating our data processing capacity.

II.

Strategic Partnerships. In this model, in addition to TIM Ads and TIM Insights, we use the segmentation capacity of our base, combined with the strength of the TIM brand to endorse the partner brand, encouraging consumers to adopt the products of our strategic partners with exclusive offers for TIM customers. In this case, TIM's remuneration is linked to the success of this adhesion and comprised of a CAC fee and an equity stake in partner companies.

II.

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

FINANCIAL SERVICES

In 2020, the Company concluded negotiations with C6 Bank 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 01, 2021, TIM announced, within the scope of this partnership, that it obtained the right to exercise a subscription warrant equivalent to an indirect equity stake of approximately 1.44% of Banco C6’s share capital arising from the achievement, in December 2020, of the 1^st level of the agreed targets. Subsequently, the Company exercised its option to acquire and convert shares issued by Banco C6, representing 1.44% of the Bank’s capital. It is important to highlight that when said option was exercised, TIM gained a minority equity stake without a controlling position or significant influence over the management of Banco C6.

2024 THIRD QUARTER RESULTS

In addition, TIM holds stock subscription options, which represent the Company's option to subscribe for 4.62% of C6's shares on September 30, 2024. Considering what has already been exercised, plus the options, TIM's potential stake in C6 Bank could reach approximately 6.06%, subject to the ongoing arbitration dispute. More details can be found in Notes 12, 31 and 37 of the ITR.

EDUCATION SERVICES

In the Education pillar, the partnership with Descomplica has already surpassed 700k subscribers in various courses such as ENEM preparatory courses, free courses, and undergraduate and postgraduate programs. Free courses focused on technology, such as ChatGPT and Artificial Intelligence for Non-Technicians, have already reached +130k subscribers in 2024.

HEALTH SERVICES

In the Health pillar, the Company operates a partnership with Cartão de Todos, with over 193k of TIM’s customers registered in the platform as of September 2024, with more than 64k of these subscriptions from the Prepaid, Control and Postpaid plans. TIM customers are still exempt from the membership fee, and those in the Control and Postpaid segment are entitled to 3 months of free monthly payments.

ENVIRONMENTAL, SOCIAL & GOVERNANCE

3Q24 HIGHLIGHTS

For the fourth consecutive year, TIM has been recognized as one of the most diverse and inclusive companies in the world, earning the 1^st global Telecom position in the FTSE Russell D&I Index 2024 (formerly the Refinitiv D&I Index). The index is one of the main tools used by investors around the world to identify companies with advanced practices in this area. Another important recognition for the company was its selection, for the second year running, to make up the IDIVERSA portfolio, a B3 index that assesses the representation of black people and women in the company and in leadership and non-leadership positions in Brazil.

In line with its commitment to tackling violence against women, TIM continues to make progress, in partnership with the Positive Women platform, with the Caminho Delas project. After transforming its 158 own stores in Brazil into safe places for women in situations of risk, the initiative has now reached the operator's resellers, expanding to a further 43 points in the states of Rio de Janeiro, São Paulo, Pernambuco, Minas Gerais and Paraíba. For this expansion, 350 employees from these establishments were trained by the startup Livre de Assédio, which supports the prevention of sexual harassment, moral harassment and discrimination.

2024 THIRD QUARTER RESULTS

TIM launched the AI Academy to train its approximately 10,000 employees in Artificial Intelligence. The initiative reinforces the company's commitment to innovation and the development of new skills. Created in partnership with companies from the Education and AI ecosystem, such as: Exame, FIAP, Alura, Google, Microsoft, among others, the academy will offer a multi-format learning journey on behavioral and technical topics that will enable the use of technology to leverage business challenges. The operator has already identified more than 100 use cases that will be leveraged by AI.

Instituto TIM, in partnership with the NGO One By One, graduated the first class of 2024 from the Exponential Education program, a technological education project aimed at disabled children and young people supported by the organization and their families. Throughout the training, the 41 students of varying ages were able to develop entrepreneurial skills using a variety of tools.

Bateria do Instituto TIM, made up of children, young people and adults with and without disabilities, ended another cycle of training for its more than 50 members in September. The project offered free music and singing lessons, as well as psychological support, in 34 weekly meetings at the Centro da Música Carioca. Performances open to the public include the TIM Music Rio festival in Copacabana and the Mini Bloco pre-carnival in Tijuca.

Instituto TIM's Edital Fortalecendo Redes has shown promising results in the development of the 10 organizations selected from the Gerando Falcões Network. In the first half of 2024, significant institutional strengthening was observed, with several nonprofit organizations expanding their digital presence and improving their operations. Some actions had a direct impact on the communities served, such as the more efficient management achieved by Cores do Mará (MA), due to a better structuring of its operations and the hiring of specialized professionals. Each organization received 100,000 reais and around 9,000 people will be impacted by the organization’s actions.

For the second year in a roll, TIM was voted the best company in the Technology and Telecommunications sector in Exame's Best and Biggest 2024 awards, one of the most recognized economic and business awards in Brazil. With more than a thousand companies from different sectors taking part, only 15 were awarded, with TIM being the only one in its sector.

In the 3rd quarter, TIM incorporated eight new plants into its operation as part of the evolution of the Distributed Generation Project (DG), totaling more than 120 units. The project is responsible for promoting the supply of the network using renewable energy plants, with a predominance of solar plants. The expectation is that by the end of 2024, about 60% of the energy used by the company will come from DG, reaching a total of 134 plants, which will serve 25 states.

2024 THIRD QUARTER RESULTS

TIM ended the 1st quarter with 1,860 active biosites on its network. These structures, similar to a common pole, are a solution for densifying the mobile access network (antennas/towers) with a very low visual and urban impact, lower cost and quick installation.

More information on TIM's ESG actions can be accessed in the Quarterly Report, available on the Investor Relations website.

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 September 30, 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.

As of September 30, 2024, TIM holds a 49% equity interest (49% as of December 31, 2023) in the company I-Systems (associated company) 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 3,535/2023, 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 September 30, 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.

(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 September 30, 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).

(In thousands of reais, unless otherwise indicated)

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
Long-term receivables	846,823
Property, plant and equipment	2,885,893

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.

As a result of the merger of Cozani by TIM S.A., which occurred on April 1, 2023 (see Note 1), all Cozani's operations were transferred to TIM S.A. As a result, as of this date, there are no longer consolidated balance sheets, with only consolidated information on income and operations being presented up to the end of year 2023.

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 September 30, 2024, the Company reported a net profit of R$ 2,105,669. The Company’s current liabilities exceeded total current assets by R$ 374,354 due to the payment of a debt in the amount of R$ 1,379,814 and the distribution of additional dividends in the amount of R$ 1,310,000, of which R$ 874,000 have already been paid, leaving a balance of R$ 436,000, in addition to the distribution of 3^rd Tranche of interest on shareholders’ equity (not paid) for the period in the amount of R$ 300,000. The Company has been recovering its working capital position through operating cash flow. On September 30, 2024, the Company’s shareholders’ equity is positive by R$ 25,977,252.

In connection with the preparation of this quarterly information, Company’s Management made analyses which confirms that the cash generated by operations up to September 30 is positive by R$ 7.9 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”.

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

September 30, 2024

(In thousands of reais, unless otherwise indicated)

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.

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.

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.

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.

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

September 30, 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.

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 non-controlling 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 gain from bargain purchase 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.

Approval of quarterly information

This individual and consolidated quarterly information was approved by the Company's Board of Directors on November 4, 2024.

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 September 30, 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.

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.

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

September 30, 2024

(In thousands of reais, unless otherwise indicated)

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.

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.

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

September 30, 2024

(In thousands of reais, unless otherwise indicated)

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

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 September 30, 2024.

IFRS 18: Presentation and disclosure of financial statements

In April 2024, the IASB issued the new standard IFRS 18 - Presentation and Disclosure of Financial Statements. This standard aims to bring more transparency and comparability to the financial performance of companies, enabling investors to make better investment decisions.

IFRS18 introduces three sets of new requirements: improved comparability of the profit or loss statement (statement of income), improved transparency of management-defined performance measures, and more useful grouping of information in the financial statements.

IFRS 18 will replace IAS 1 - Presentation of Financial Statements.

This standard becomes effective for years beginning on or after January 1, 2027, and companies may apply it earlier subject to authorization by relevant regulators.

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

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.

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

September 30, 2024

(In thousands of reais, unless otherwise indicated)

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.

Amendment to IFRS 9 – Disclosure of quantitative information for contractual terms

In May 2024, the IASB issued amendments to IFRS 9 related to financial assets, establishing that entities must disclose quantitative information, such as a range of possible changes in contractual cash flows. This means that entities need to provide both qualitative and quantitative information about the contractual terms that may impact the value of said cash flows. For example, possible changes in contractual interest rates arising from contingent events associated with ESG (environmental, social and governance) targets must be disclosed.

The amendments are effective for annual financial statement periods starting on or after January 1, 2026.

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

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

Accounting estimates and judgments are continuously assessed 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).

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 18), 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.

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 equals the book value recorded as at September 30, 2024 and December 31, 2023.

Amounts expected to be received in more than 12 months are classified as long-term.

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). Until September 30, 2024, the total recognized inflation updating was R$ 125 million (R$ 113 million until December 31, 2023), representing the accumulated value throughout the transaction.

(In thousands of reais, unless otherwise indicated)

In the third quarter of 2023, TIM’s lawsuit received a favorable final and unappealable decision and in September 2023, 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, in September 2023, 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. Throughout 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$ 197 million in 2024 and R$ 151 million in 2023.

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.

Social contribution	72,754	64,407

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.

(In thousands of reais, unless otherwise indicated)

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 September 30, 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.

The amounts recorded are as follows:

	Parent Company

The Operating Inspection Fee (TFF) for the years 2020, 2021, 2022, 2023 and 2024 of TIM S.A. and TFF for 2022 of Cozani had its payments suspended by virtue of an injunction and, therefore, still do not have a specific date for payment. See Note 22 for details.

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

(iii) As of the 1Q20, TIM S.A. excludes the portion of acceleration of depreciation of movable assets belonging to property, plant and equipment from the calculation basis of the IRPJ and CSLL, due to their uninterrupted use in three operating shifts, supported by technical expert report, as provided for in Article 323 of the RIR/2018, or by the adequacy to the tax depreciation provided for in IN 1700/2017. Such tax adjustment generated a deferred liability of R$ 976 million until September 30, 2024 (R$ 891 million up to December 31, 2023) and applied as of January 1, 2020.

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

Deferred income tax and social contribution (active installment)	Tax losses and negative basis	Temporary differences	Total
2024	53,167	573,387	626,554
2025	-	224,125	224,125

Total	53,167	3,262,187	3,315,354

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

The Company used deferred credits arising from tax losses and negative social contribution basis in the amount of R$ 148 million by September 2024 (R$ 75 million as of September 30, 2023).

Such financial assets and liabilities are subsequently measured at fair value through profit or loss. Changes arising from the fair value measurement, where applicable, shall be recognized in the result when incurred, under the line of financial income.

(i) On March 23, 2020, TIM S.A. and BANCO C6 S.A. concluded the negotiations over a strategic partnership aimed at developing combined offerings with special benefits to the customer bases of Partners.

In July 2020, the first offering was launched in partnership with Banco C6, with special conditions to TIM customers who are also C6 customers. The innovating partnership provides great potential to generate value for both companies through user base growth and greater customer loyalty.

On February 1, 2021, TIM announced that, within the scope of this partnership, the right to exercise Subscription Warrant equivalent to the indirect interest of approximately 1.44% of Banco C6’s share capital Banco C6 as a result of meeting, in December 2020, the 1^st level of the agreed targets. Subsequently, the Company exercised its option to acquire and convert C6 shares, which represents approximately 1.44% of the Bank and totals R$ 162,958. It is worth highlighting that once the option is exercised, TIM started holding a minority position and does not have a position of control or significant influence in the management of C6.

(i) The Company has invested approximately R$ 189 million (R$ 54 million in 2023) in the Investment fund focused on 5G solutions “Upload Ventures Growth”.

Out of this total amount, it is worth emphasizing that on April 30, 2024 and September 23, 2024, the Company made contributions of approximately US$ 15 million (R$ 77 million) and US$ 10 million (R$ 54 million), respectively, to the 5G Fund, reinforcing its commitment to boosting the development of solutions based on 5G technology.

According to the requirements of IFRS 9 / CPC 48, the financial instrument must be valued at its fair value and the Company must disclose the level classification of each financial instrument. See Note 37 in the section on Financial instruments measured at fair value for details of this information.

Investment

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

Cozani

As mentioned in Note 1.2, on April 20, 2022, TIM S.A. (jointly with other buyers Telefônica Brasil S.A. and Claro S.A.), after complying with the precedent conditions established by the Administrative Council for Economic Defense (CADE) and ANATEL, concluded the process of acquiring the mobile assets of Oi Móvel S/A – Under Court-Ordered Reorganization.

With the conclusion of the Transaction, TIM S.A. now holds 100% of the share capital of Cozani, a company that corresponds to the part of the unit of assets, rights and obligations of Oi Móvel acquired by the Company. On April 1, 2023, TIM S.A. acquired Cozani, therefore, for all effects, the latter was dissolved and consequently, for all purposes and effects, TIM S.A. does not have equity interest in Cozani on September 30, 2024 or December 31, 2023.

I-Systems

In November 2021, as a result of the spin-off of net assets from the broadband business and creation of I-Systems, TIM S.A. disposed of 51% of its equity interest on behalf of IHS. As a result of this transaction, a loss of control took place and TIM S.A. no longer consolidates the Company, recording the investment in the associated company in the amount of R$ 1,612,957, at fair value, for the remaining minority interest (non-controlling) of 49%.

(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 concluded 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.

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. On September 30, 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 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.

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 of assets.

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.

Software maintenance costs are recognized as an expense, as incurred. Development costs that are directly attributable to software product design and testing, and are identifiable and exclusive, controlled by the Company, are recognized as intangible assets when the capitalization criteria are met.

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

(d) Goodwill registered

The Company has the following goodwill, based on the expected future profitability on September 30, 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 totaling R$ 2,636,426, which is recorded on September 30, 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 Company, 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 September 30, 2024 and December 31, 2023.

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.

NOTES TO THE QUARTERLY INFORMATION - continued

(In thousands of reais, unless otherwise indicated)

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, concluding that there is no need to form a provision for impairment since the fair value less the cost of sales is higher than the total book value of the cash generating unit.

On September 30, 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 IFRIC4/ICPC3 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, occurred in 5 semi-annual installments between 2022 and 2024, and were monetarily restated by the IGP-DI. The Company evaluated the application of the concept of adjustment to present value (“AVP”) upon initial recognition (R$ 83 million).

The 3.5GHz radio frequency was not readily available, requiring spectrum cleaning activities to be available for use, and, thus, it was registered in assets in progress (R$ 270 million). Therefore, the obligations related to this activity, to be carried out by EAF (R$ 2,104 million) were also recorded under assets in progress. The disbursements with the EAF, as provided for in the Public Notice, were restated by the IGP-DI until the disbursement dates. Such disbursements took place in 2 installments in 2022 (R$ 1,090 million in February and R$ 1,133 million in May) to EAF.

Furthermore, as described above, the Company capitalizes loan costs for qualifying assets that require a substantial period of time to be in a condition for use as intended by Management. This concept includes the 3.5GHz radio frequency. 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.

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 September 30, 2024, this credit is R$ 44,345 (R$ 80,963 on December 31, 2023).

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 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) Other leases:

Besides the aforementioned lease agreements, the Company also has tower lease agreements that are part of the lease obligations under the agreement with American Tower.

The present value, principal and interest value as of September 30, 2024 for the above contracts was estimated month-to-month, based on the average incremental rate of the Company’s loans, namely 12.14% (13.63% in 2023).

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.

Loans and financing

They are classified as financial liabilities measured at the amortized cost, and represented by non-derivative financial liabilities that are usually traded before maturity.

In the initial recognition, they are recorded at the fair value and after the initial recognition they are measured based on the effective interest rate method. Appropriations of financial expenses according to the effective interest rate method are recognized in income (loss), under financial expenses.

Guarantees

(i) Certain receivables from TIM S.A.;

(ii) Do not have a guarantee.

According to the schedule established for the Company’s debt maturities, in the period ended September 30, 2024, debts in excess of R$ 1 billion, with charges above 110% of the CDI rate, were settled at their original maturities. Conversely, R$ 387 million (May 2024) and R$ 116 million (July 2024) were brought in under a contract previously signed with BNB, with financial charges below 57% of the CDI rate, reducing the weighted cost of the company’s financing.

The Company's financing, contracted with BNDES, was obtained for the expansion of the mobile telephone network and has restrictive contractual clauses that provide for the fulfilment of certain financial and non-financial rates calculated every quarter. Financial indices are: (1) Shareholders' equity over total assets; (2) EBITDA on net financial expenses; (3) Total financial debt on EBITDA and (4) Short-term net financial debt to EBITDA. The Debentures issued by TIM S.A. (2^nd issue in a Single Series) have a financial ratio covenant calculated semiannually. The index is the Net Financial Debt on EBITDA. The Company has been complying with all the established ratios.

Company’s loans and financing on September 30, 2024 due in long-term is in accordance with the following schedule:


2025			73,477
2026			882,616

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, BNP Paribas, Debentures and BNDES and BNB, the fair value of these loans is considered to be the present value of the long position of the swap contracts that protect the Company from changes in exchange rates and interest. The fair value of operations on September 30, 2024 and December 31, 2023 is detailed in the table below:

	September 2024	December 2023

(i) In 2020, to minimize the impacts of the pandemic, Provisional Act 952, dated April 15, 2020, was enacted, authorizing the postponement of payment of taxes to August 31, 2020, such as TFF, Condecine and CFRP. In the 2020 amounts, the Company made a partial payment to CFRP and Condecine, but due to a preliminary injunction in court, there was no need to pay the Fistel (TFF), which remains outstanding until the final and unappealable decision.

In 2021 to 2024, there was partial payment relating to CRFP and Condecine annually, with TFF payments suspended based on an injunction issued by the Regional Court of the 1^st Region.

As of September 30, 2024, the total value of the obligation relating to TFF is R$ 3,168 million, of which R$ 2,509 million in principal and R$ 659 million in interest on arrears (as of December 31, 2023, the total was R$ 2,554 million, of which R$ 2,087 million in principal and R$ 467 million in interest on arrears).

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.

In June 2024, TIM’s Conduct Adjustment Term (TAC) ended. However, due to the adverse climate event that affected the state of Rio Grande do Sul in the months of April and May 2024, for 19 municipalities located in that state, the service deadline was extended in this particular case until September 30, 2024, in a new Amendment to the TAC which was formalized between the parties.

The Company will continue to fully implement internal monitoring mechanisms to meet inspection needs and proof of compliance with obligations and commitments.

The Company 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.

c. Profit reserves

c.1 Legal Reserve

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

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

c.2 Statutory reserve for expansion

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

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

c.3 Tax incentive reserve

The Company enjoys tax benefits that provide for restrictions on the distribution of profits. According to the legislation that establishes these tax benefits, the amount of tax that is no longer paid due to exemptions and reductions in the tax burden may not be distributed to members and will constitute a reserve of tax incentive of the legal entity. This reserve can only be used to offset losses or increase share capital. On September 30, 2024, the accumulated amount of benefits enjoyed by the Company amounts to R$ 2,362,239 (R$ 2,362,239 on December 31, 2023).

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

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:

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

For the 2021-2023 and 2024-2026 plan, the term of validity has the same periodicity of 3 years related to its vesting. These Plans, in addition to considering the transfer of shares, also provides for the possibility of making payment to participants of the equivalent amount in cash.

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

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.

NOTES TO THE QUARTERLY INFORMATION - continued

(In thousands of reais, unless otherwise indicated)

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 trading 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 September 30, 2024 is R$ 101,349 (R$ 122,137 on September 30, 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.

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.

112

TIM S.A.

NOTES TO THE QUARTERLY INFORMATION - continued

September 30, 2024

(In thousands of reais, unless otherwise indicated)

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 IFRS9/CPC48.

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 September 30, 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 September 30, 2024 and December 31, 2023, the Company maintains its financial resources applied to Interbank Certificates of Deposit (CDI), which substantially reduces this risk.

(iii) Credit risk inherent in the provision of services

The risk is related to the possibility of the Company computing losses derived from the inability of the subscribers to honor the payments of the invoiced amounts. To minimize this risk, the company preventively performs credit analysis of all orders imputed by the sales areas and monitors the accounts receivable of subscribers, blocking the ability to use services, among other actions, if customers do not pay their debts. There are no customers who have contributed more than 10% of net accounts receivable on September 30, 2024 and December 31, 2023 or revenues from services rendered during the periods ended September 30, 2024 and 2023.

September 30, 2024

(In thousands of reais, unless otherwise indicated)

(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 September 30, 2024 and 2023. There are no customers who contributed more than 10% of the net receivables from the sale of goods as of September 30, 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 18 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 September 30, 2024 corresponds to R$ 523 million (R$ 502 million as of December 31, 2023).

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.

(In thousands of reais, unless otherwise indicated)

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 September 30, 2024, there are no types of margins or guarantees applied to the company's derivative transactions.

Based on mandatory market developments, we changed the index of our debt with KFW/Finnvera 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 September 30, 2024 and December 31, 2023 are shown in the following table:

September 30, 2024

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 increases 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 September 30, 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.
