To the shareholders, board members and directors of

TIM S/A

Rio de Janeiro – RJ

Opinion

We have audited the individual and consolidated financial statements of Tim S/A (the “Company”), identified as Individual and Consolidated, respectively, which comprise the balance sheets as at December 31, 2023, and the statements of income, of comprehensive income, of changes in shareholder’s equity and cash flows for the year then ended, and notes to the financial statements, including a summary of material accounting policy information.

In our opinion, the accompanying financial statements present fairly, in all material respects, the individual and consolidated financial position of TIM S/A as at December 31, 2023, and its individual and consolidated financial performance and cash flows for the year then ended in accordance with the accounting practices adopted in Brazil and with the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB).

Basis for opinion

We conducted our audit in accordance with Brazilian and International Standards on Auditing. Our responsibilities under those standards are further described in the Auditor’s responsibilities for the audit of the individual and consolidated financial statements section of our report. We are independent of the Company and its subsidiaries in accordance with the relevant ethical principles set forth in the Code of Professional Ethics for Accountants, the professional standards issued by the Brazil’s National Association of State Boards of Accountancy (CFC) and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Emphasis of matter on the restatement of corresponding figures

As mentioned in the note 2(h) to the financial statements, as a result of the changes in specifics cash flows, the corresponding figures referring to the prior year of the individual and consolidated statements of cash flows, presented for comparison purposes, have been adjusted and are being restated as provided for by CPC 23 (IAS 8) – Accounting Policies, Changes in Accounting Estimates and Errors. Our opinion has not been modified with respect to this matter.

Independent auditor's report on the Financial statements

Key audit matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial statements of the current period. These matters were addressed in the context of our audit of the individual and consolidated financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. For each matter below, our description of how our audit addressed the matter, including any commentary on the findings or outcome of our procedures, is provided in that context.

We have fulfilled the responsibilities described in the Auditor’s responsibilities for the audit of the individual and consolidated financial statements section of our report, including in relation to these matters. Accordingly, our audit included the performance of procedures designed to respond to our assessment of the risks of material misstatement of the financial statements. The results of our audit procedures, including the procedures performed to address the matters below, provide the basis for our audit opinion on the accompanying financial statements.

Provision for tax related contingencies

As disclosed in the note 24 to the financial statements, the Company is a party to numerous tax claims and proceedings at different jurisdictional levels, which amounted to R$19,903 million, as of December 31, 2023, for which a provision amounting to R$666 million was recorded in the financial statements, while the remaining R$19,236 million was disclosed as possible losses, in accordance with CPC 25 (IAS 37) Provisions, Contingent Liabilities and Contingent Assets. The determination of the provision and disclosures related to the tax contingencies involves significant judgment from management, including their analysis of the matters in dispute, the opinion of internal and external legal counsel and the estimation surrounding their ultimate resolution.

In addition, in view of the magnitude of the amounts involved, any changes in estimates or assumptions that impact the determination of the loss prognosis may have significant impacts on the Company’s financial statements. Accordingly, this was considered a key audit matter.

How our audit conducted this matter

Our audit procedures included, among others: (a) obtaining an understanding and evaluation of the design of controls over the identification and evaluation of tax claims, including management’s process to determine whether the technical merits are more-likely-than-not to be sustained in court; (b) involving our tax professionals to assess the Company’s technical merits regarding certain matters in dispute, obtaining and analyzing external legal opinions, obtaining internal and external legal counsel confirmation letters, meeting with internal legal counsel to discuss certain tax disputes, and obtaining a representation letter from the Company’s internal legal counsel; and (c) assessing the adequacy of the disclosures made by the Company in note the 24 in respect of provision for tax related contingencies.

Independent auditor's report on the Financial statements

Based on the result of audit procedures performed in the provision for tax contingencies and related disclosures, which is consistent with management’s assessment, we understand that the measurement of tax claims assessed as probable and possible loss, as well as the respective disclosures in the note 24 are acceptable in the context of the financial statements taken as a whole.

Other matters

Statements of value added

The individual and consolidated statements of value added (SVA) for year ended December 31, 2023, prepared under the responsibility of Company management, and presented as supplementary information for purposes of IFRS, were submitted to audit procedures conducted together with the audit of the Company’s financial statements. To form our opinion, we evaluated if these statements are reconciled to the financial statements and accounting records, as applicable, and if their form and content comply with the criteria defined by NBC TG 09 – Statement of Value Added. In our opinion, these statements of value added were prepared fairly, in all material respects, in accordance with the criteria defined in abovementioned accounting pronouncement and are consistent in relation to the overall individual and consolidated financial statements.

Other information accompanying the financial statements and the auditor’s report

Management is responsible for such other information, which comprise the Management Report.

Our opinion on the individual and consolidated financial statements does not cover the Management Report and we do not express any form of assurance conclusion thereon.

In connection with our audit of the individual and consolidated financial statements, our responsibility is to read the Management Report and, in doing so, consider whether this report is materially inconsistent with the financial statements, or our knowledge obtained in the audit or otherwise appears to be materially misstated. If, based on the work we have performed, we conclude that there is a material misstatement of the Management Report, we are required to report that fact. We have nothing to report in this regard.

Responsibilities of management and those charged with governance for the financial statements

Management is responsible for the preparation and fair presentation of the individual and consolidated financial statements in accordance with the accounting practices adopted in Brazil and with the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB), and for such internal control as management determines is necessary to enable the preparation of financial statements that are free of material misstatement, whether due to fraud or error.

In preparing the individual and consolidated financial statements, management is responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

Those charged with governance are responsible for overseeing the Company’s and its subsidiaries’ financial reporting process.

Independent auditor's report on the Financial statements

Auditor’s responsibilities for the audit of the financial statements

Our objectives are to obtain reasonable assurance about whether the individual and consolidated financial statements as a whole are free of material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with Brazilian and International standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

As part of an audit in accordance with Brazilian and International Standards on Auditing, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

Identified and assessed the risks of material misstatement of the individual and consolidated financial statements, whether due to fraud or error, designed and performed audit procedures responsive to those risks, and obtained audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

Obtained an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s and its subsidiaries’ internal control.

Evaluated the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

Concluded on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the individual and consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Company to cease to continue as a going concern.

Evaluated the overall presentation, structure and content of the individual and consolidated financial statements, including the disclosures, and whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

Independent auditor's report on the Financial statements

We communicate with those charged with governance regarding, among other matters, the scope and timing of the planned audit procedures and significant audit findings, including potential significant deficiencies in internal control that we may have identified during our audit.

We also provided those charged with governance with a statement that we have complied with relevant ethical requirements, including applicable independence requirements, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determined those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

2023 MANAGEMENT REPORT AND EARNINGS ANALYSIS

Message from Management

We are very pleased that 2023 was an outstanding year with great achievements and record-high results. Such outcome was a consequence of navigating well in the new environment of the Brazilian mobile market, our core business segment, and exploring opportunities that are emerging.

Our Core - The Mobile Market

During our Investor Day in November, we explained that the Brazilian mobile market is healthier than ever before, supporting a more-for-more strategy. New market dynamics following the consolidation and favorable demand are driving a better environment to operate.

This new environment is characterized by: (i) a new, more rational, market dynamic with customers focused on value and quality, (ii) essentiality of the service mobile, (iii) opportunity to increase usage with increased demand for data, and (iv) price accessibility.

Our Strategy – Next Generation TIM

We have a clear strategy to craft the Next Generation TIM. Under this framework, we defined four pillars, Mobile, B2B, Broadband and Efficiency, which are developed integrating our people, society, and the environment into our business strategy.

This integration propels our ESG practices to be recognized as one of the most developed in the country. TIM ranked 12th among the best companies to work for in Brazil in the Great Place to Work selection. Sustainalytics also awarded us as ESG industry top-rated. S&P listed TIM among the most sustainable telecom companies in the world. And we are the most diverse and inclusive company in LatAm and the number one telco in the world ranked by Refinitiv.

Our strategic pillars are summarized as follows.

Mobile: where TIM generates most of its results and where we aim to be the preferred operator for customers by developing the Best Service, Best Network and Best Offer;

B2B: the Company is shaping a new IoT^[1] -based market with services and connectivity to address an exponential growth opportunity.

Broadband: where TIM wants to grow profitably using a selective approach while keeping future options open;

Efficiency: the Company has this pillar as inherent to its operation and carries out all its actions with strict discipline in the allocation of capital resources.

2023 MANAGEMENT REPORT AND EARNINGS ANALYSIS

Our Achievements^[2] – A Historical Year

Our service revenues grew, in 2023, 10.7% year-on-year, totaling more than 23 billion Reais, a record high number in our history. With costs under control, our EBITDA grew more than 14% to reach another record in our history, 11.7 billion Reais.

In this context, our 2023 EBITDA margin expanded to almost 49%—the highest among the large telcos in Brazil and LatAm. Another metric that measures our efficiency in allocating resources is the Capex-to-Sales ratio. We closed 2023 with the best result ever, just below 19%, contributing to our operating free cash flow^[3] growing more than 58% year-on-year, summing to 4.2 billion Reais. Additionally, our Net Income rose to 2.7 billion Reais after expanding more than 50% year-over-year. These results explain why we were confident in raising our shareholder remuneration target to 2.91 billion reais, from 2.3 billion.

During 2023, we worked extensively to deliver improvements in customer experience. We seek the Best Service by digitalizing the interactions to accelerate and improve demand resolution. And we were best in class in all resolution rankings of Brazil. At the same time, if a human attendant services a client, the satisfaction with this interaction must be very high. And we delivered that – call center NPS improved more than 40% in the fourth quarter.

Meanwhile, we consolidated our leadership in network coverage and quality in Brazil, confirming that we have the Best Network. We developed the largest 4G and 5G coverage, being the only operator to cover all the cities of Brazil. Our network was also the most awarded among the Brazilian operators, and we ranked number one in Consistency Quality, the most relevant KPI to measure a customer's actual experience.

To complete, we are innovating to create the Best Offer, leveraging new concepts and partnerships to generate novelty and distinctiveness. We’ve launched the first trial offer in LatAm to encourage customers to test our services. We expect this tool to be relevant in changing clients' perceptions of our quality. We just launched commercially our partnership with Ambev. We are expanding the benefits, using the cashback in the Zé Delivery app as a loyalty tool.

These mobile developments are driving us to post the highest blended (prepaid + postpaid) ARPU in the industry, close to 30 reais and growing nearly 13% year-over-year. At the same time, we are improving churn in postpaid, increasing upsell results with upward migrations, and seeing a rise in prepaid spending.

Those notable achievements have been made possible by the contribution of every TIM employee. And we are proud to lead a team of committed and hard-working people with an engagement level of above 90%.

Conclusion and Perspectives

When we started the year, we set challenging but achievable targets. As we executed our plan, results began to come faster, which led to the best performance of TIM’s history in many KPIs.

^[2] All financial figures are normalized to non-recurring items to better represent business dynamics.

2023 MANAGEMENT REPORT AND EARNINGS ANALYSIS

We completed a quarter of a century of existence over-delivering on every front.

Projections x Results 2023
Indicator	Short Term Projection	Result
Service Revenue Growth	High single-digit^[4] Y/Y	+10.7% Y/Y
EBITDA growth	Low double-digit² Y/Y	+14.2% Y/Y
Investments	CAPEX on net revenues Ratio: <20%	18.9%
EBITDA-AL growth minus CAPEX	Double-digit² A/A	+58.2% Y/Y
Dividends announced to shareholders	> R$ 2.9 Bln	R$ 2.91 Bln (R$ 1.6 bln in IOC and R$ 1.31 bln in dividends^[5])

In this scenario we project for the coming years a sustainable growth in Service Revenue above inflation and an expansion of EBITDA with positive evolution in the margin. This dynamic combined with maintaining the level of investments that benefit from the efficiency of new technologies, such as 5G, should promote an improvement in our operating free cash flow. All of this will enable us to continue evolving our shareholder remuneration strategy and reinvest in growth avenues such as B2B and Broadband.

We are on a long journey to become the most preferred telco, so we must keep focused on executing our strategy, adjusting to the environment, when necessary, but never losing sight of our end goals.

2. Economic and Industrial Overview

2.1. Macroeconomic Environment

The year 2023 overall was positive for Brazil. After a 2022 with the most polarized presidential election in history, the country needed to advance important reforms and also carry out a fiscal adjustment of a specific magnitude. At the end of the year, the approval of a tax reform was achieved, even if only a part of it, which had been discussed for 30 years, in addition to projecting the zeroing of the primary deficit by 2024. The movement of the The Central Bank, which from August began a process of gradual reduction of the SELIC, closing the year at 11.75% per year.

Another favorable fact was the decrease in the unemployment rate 7.8%^[6] in 2023, lowest number since 2014 and 7.4% in the fourth quarter continuing a series of declines over the last quarters, impacted by the process of immunization against COVID-19 started in 2022. With this quarter's results, the absolute number of unemployed people decreased marginally compared to the previous quarter, to 8.1 million people.

2023 MANAGEMENT REPORT AND EARNINGS ANALYSIS

Inflation, measured by the Extended Consumer Price Index (IPCA), ended 2023 at 4.62%^[7], above of the target the estimated target for the year (3.25%), but inside of the margin of the target of 1.5%. Despite having the second largest nominal increase (7.14%), the Transport group had the greatest weight in the general inflation index, with 1.46 percentage points. Gasoline, which is part of the group, was the sub-item with the greatest weight among the 377 that make up the IPCA. In the year, the increase was 12.09%, with an impact of 0.56 p.p. Also in the group are two other sub-items that make up the podium of the most relevant price increases for the IPCA. Registration and licenses increased by 21.22% in the year and weighed 0.53 p.p. in the IPCA. Air tickets come in third place in the ranking, as they rose 47.24% in the year and contributed 0.32 p.p. to the index. In the Health and personal care group, the biggest contribution came from the health plan (11.52% increase and 0.43 p.p. in the index). In Housing, the main positive contribution came from residential electricity (9.52% and 0.37 p.p.).

In 2023, the exchange rate recorded a considerable volatility, with the Real appreciating against the US dollar in relation to the end of the previous year. At the last closing period, the American currency ended quoted at R$ 4.85, accounting for a decrease of 8.06%. Uncertainties regarding American inflation and external factors such as the War between Russia and Ukraine in addition to the confrontation that began in October 2023 between Israel and Hamas, contributed to the oscillation scenario presented by the currency. In relation to the Brazilian Real, the American currency recorded a high of R$ 5.45 against a low of R$ 4.72 during the year, accounting for a change of 15.5% in a scenario of domestic uncertainties, fiscal risks and many discussions about, for example, the Tax Reform Proposal, in addition to the new expenditure framework. Both measures would be approved months later and helped reduce market uncertainty, The trade balance ended the year with a surplus of US$ 98 billion, accounting for an increase of 60.6% compared to the end of 2022. Exports closed the year at US$ 339.7 billion and recorded a positive change of 1.7% compared to 2022. Imports recorded US$ 240.9 billion, accounting for a decrease of 11.7% in the annual comparison. The superávit value represent the highest record of the entire historical series.

The international scenario was, for one more year, marked by many uncertainties and volatility with high inflation rates with resistance to be reduced, led by commodity, food, and logistical and production bottleneck, as well as a reduction in GDP growth rates in most countries. The United States showed a slowdown in the inflation rate to 3.4%, and GDP growth of 2.5% compared to an expansion of 2.1% in 2022. The economy in Europe shows a low pace of growth, greatly impacted by the effects of the war between Russia and Ukraine and more recently the conflict between Israel and Hamas, affected the pace of the resumption of the post-pandemic economy. The GDP of the Organization for Economic Co-operation and Development (OECD) member countries increased 0.7% in the third quarter. The International Monetary Fund (IMF) points to a forecast of 3.0% ^[8]growth for the global economy in 203.

2023 MANAGEMENT REPORT AND EARNINGS ANALYSIS

2.2. Particularities of the Telecommunications Sector

The telecommunications sector in Brazil is marked by the high degree of competition and by the effective regulation of the National Telecommunications Agency (ANATEL), which has the mission of “promoting the development of telecommunications in Brazil, in order to provide it with a modern and efficient telecommunications infrastructure, capable of offering society appropriate and diversified services at fair prices nationwide”.

Throughout its trajectory, the sector has always been impacted by fierce competition on the Brazilian market, which can be seen by the presence of very aggressive offers from the viewpoint of the content available to customers and the reduced level of prices charged by operators in general. However, in recent years, this competition has moved more towards issues related to quality and service, becoming more rational from the point of view of prices. In the last year, it is possible to say that we had a process of continuity of this transition to a new model of competition.

In 2023, the acquisition process of the mobile operation assets of Oi Móvel S.A. was fully completed by TIM, Telefônica Brasil S.A. and Claro S.A., after all the precedent conditions provided for by the National Telecommunications Agency (ANATEL) and by the Administrative Council for Economic Defense (CADE) were fulfilled, with the approval by the Arbitration Chamber Court of the agreement regarding the closing price, concluded between the buyers, TIM, Telefônica Brasil S.A. and Claro S.A and the seller, Oi S.A..

Finally, the year 2023 was marked by the continuity of the implementation and expansion of 5G technology in Brazil, which seeks to meet the demand for higher connection speeds. In this context, TIM ended 2023 having implemented 5G technology in 137 cities, includingall 27 capital cities of the country, with a much higher number of antennas than required by ANATEL, thus providing a better experience for the user.

3. TIM Services

Demonstrating this differential, in 2023, TIM started several partnerships on the most varied fronts, with emphasis on the Content and Security segments (partnership with Deezer and HBOMAX, for example), Education (Descomplica), Retail (Zé Delivery) and Health (Cartão de Todos). This simultaneously generates social impact and solid revenue growth, which allows the Company to accumulate Free Operating Cash Flow.

3.2. Strategy

With the update of the Company’s strategic plan, TIM reinforces the search for sustainable business growth considering all stakeholders and aiming to create value for each of them. In this context, the plan designed by the Company is centered on strategies for the evolution of the existing business with incremental innovations and initiatives that improve TIM's relative position. At the same time, new fronts are opened seeking business transformation with more disruptive changes, entry into new markets and capture opportunities that go beyond TIM's core business. Among the levers to achieve our aspiration, we can mention the following:

In 2023, we have once again evolved people development practices, connected to the new Cultural Values and the needs of the organization, with transversal and customized actions for different audiences, to support the achievement of the objectives of the strategic plan.

Once again, we evolved the performance management process through feedback from TIMe itself, to add even more value to eligible employees. In addition to including new elements of Cultural Values in the TIM Competency Model, we also enhanced the role of Leadership in project evaluation.

Throughout 2023, the following were contemplated: the closing of the 2022 Performance cycle and the launch of the 2023 Performance cycles.

At the end of cycle 22, we achieved 94.9% participation in the Assessment stage and 93.8% adherence to the Feedforward registry.

Two other initiatives launched in 2023 that contributed to people's development were the Mentoring classes for Interns and Culture Ambassadors, involving 81 interns and 45 ambassadors respectively. In mentoring for interns, we trained and invested in 58 internal mentors. When mentoring ambassadors, we count on renowned professionals in the market, with experience in cultural transformations to support them in their work.

For Talent Management, in 2023 we invested in a Talent Analytics study and implemented a Talent Committee involving executives from the company's operations area (Chief Revenue Officer) to not only map the talents of the board, but also refine the methodology designed internally for roll-out with other areas of the company.

For senior leadership, we continue to map the executives who will guarantee the long-term continuity of the business. Another wave of a Top Executive Assessment in partnership with an external Leadership Advisory consultancy helped us map and accelerate the development of senior executives who will feed the company's succession plan.

TIM also continued personalized learning journeys for the different areas based on the different needs related to the activity.

To support and evolve with the learning process, we prioritize cultural education, upskilling and reskilling programs and actions, as part of our TIM Mais Knowledge Learning Hub, which consolidates individual and collective journeys for employee learning on strategic business topics, such as digital mindset and skills, innovation, governance, customer experience, change management, among others.

Following the approach, we opted for leaner actions and directly connected to the themes in order to not overload our collaborators. We carried out a campaign to publicize the initiatives, which ranged from lives with experts on the topics to reinforcement on the importance of collecting electronic waste in offices and stores, in order to engage our collaborators to dispose of their equipment at collection points. available at our facilities.

All these practices resulted in 13,301 applications, a 10% increase compared to the 2022 program and a record number of applications for TIM Internship Programs.

2023 MANAGEMENT REPORT AND EARNINGS ANALYSIS

In line with digital skills, the next phase involved an interactive group experience, through a virtual Escape Room, providing candidates with an immersion in TIM’s various environments, such as the Concept Store, the People, Culture & Organization area and the Technology Laboratory. This phase allowed participants to demonstrate skills such as logical reasoning, team collaboration, decision making, communication and leadership.

The Internship Program continues to play a vital role in strengthening TIM's culture of diversity and inclusion. This year, we overcame the challenge of attracting a diverse audience, reflecting a representation of more than 80% of interns identified in at least one of the diversity pillars.

The Internship Program solidifies TIM's ongoing commitment to excellence, diversity and innovation.

Young Apprentice Program: in 2023, we started a talent pool at Gupy that has already accumulated more than 5k applicants for TIM's Young Apprentice opportunities. An additional challenge was the internalization of the selection process for these vacancies, which generated savings of more than 80 thousand reais for the company, in addition to ensuring a selection process that was more aligned with the company's culture. We hired 180 people between 18 and 24 years old across the country, who started their professional careers at TIM. Of this number, 64% are women and 46% declared themselves black or mixed race. The program has a strong social impact and is aimed mainly at people in socially vulnerable situations. We form partnerships with third sector institutions that reinforce this premise, such as PROA and the consolidation of the Employability Pact Between Heaven and Favela. This group's journey involves theory and practice, with vacancies available in administrative areas and stores.

During the development journey, apprentices have the opportunity to learn basic skills that will help them launch their professional career and prepare for future challenges. This year, 19 young people had the opportunity to take on other positions in different areas.

The area, recently renamed Cultural Education & Inclusion Management, has the mission of ensuring the evolution of the company's inclusive culture, through the construction, implementation and management of specific policies, projects and programs, as well as promoting initiatives that contribute to the appreciation of diversity and promoting inclusion, at TIM and in society.

Understanding that people's involvement is fundamental to the evolution of culture, in 2020 we launched 5 Affinity Groups, one for each pillar detailed on the next page, which today have approximately more than 500 employees.

Two classes were held during the months of August and September 2023, in the cities of Rio de Janeiro and São Paulo, training 30 people, of which 8 were hired to work in our own stores. In August, a Pact for the Employability of Pedra Lisa, located in the Morro da Providência region of Rio de Janeiro, was signed with Gerando Falcões, which is served by Gerando Falcões through the Favela 3D Program. In the document, TIM made a commitment to building a fairer and more inclusive society, by combating unemployment in the locality.

As part of support and reception, a specific social assistance service on the topic was made available to employees.

To support the process of acculturation and learning about topics related to Diversity and Inclusion, TIM carries out initiatives to combat unconscious biases through training for the professional public and leadership. In addition, it has the Conscious Keyboard, which works to eliminate expressions and words from everyday life that carry racist, sexist, ageist, ableist and LGBTphobic connotations. The application alerts users about the use of discriminatory words, explains the origin of the terms and proposes replacements. In addition, TIM also has diversity guides on the company's website that cover topics such as inclusive leadership, inclusive and respectful attitudes on the pillars of LGBTI+, PWD, ethnicity, gender and generations.

Throughout 2022 and 2023, TIM developed initiatives such as educational and communication campaigns, in alignment with the annual Diversity & Inclusion calendar, which includes the main global dates according to the UN calendar and highly representative national dates. In addition to topics related to the 5 representative pillars, we work on other topics of great relevance, such as fatphobia, HIV/AIDS and religious intolerance. Another action was TIM Convida, a series of digital events, open to the whole of society, with the aim of discussing current issues related to D&I, with speakers recognized for their work on the topic. In addition, the “Chama pro TIMe” Project was continued in all pillars worked at TIM Brasil, in which collaborators are invited to nominate candidates from minority groups for opportunities at TIM. We carry out specific training for leaders on the pillars and themes of D&I, in addition to having mandatory training on Diversity and Inclusion in our onboarding.

This policy may be activated in the three years following the calculation or disbursement of the award object of this action or fiscal year, whichever is older. The Clawback policy may be triggered even if the respective Participant has, on the date of the activation decision, interrupted - for any reason, including retirement - the employment relationship with the Company.

The activation of the Clawback policy does not exclude the Company's right to compensation for any additional damages, nor does it in any way exclude the possibility of further initiatives, such as disciplinary measures, termination and/or any other legal action that is permitted and provided for in accordance with the legislation in force. In this sense, the possibility of its activation is an additional element and not a substitute for other actions that may be taken by the Company.

7.1. Operating Revenue

*The Customer Platform includes revenues from new initiatives such as Financial and Educational Services and Mobile Advertising.

At the end of 2023, the Total Net Revenue reached R$23,834 million, compared to R$21,531 million in 2022, a growth of 10.7% YoY, driven by the positive performance in all lines: (i) Mobile Service Revenue expanding by 11.2'%, resulting from a combination of ARPU growth, migration of customers to plans with higher value, improvement in customer experience and revenue coming from customers that arrived from Oi Mobile, which was incorporated in May 2022; (ii) TIM UltraFibra Revenue sustaining its growth pace, up by 9.7% YoY; and (iii) Product Revenue increasing by 8.7% YoY, as part of the prioritization of higher value devices.

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

Mobile Service Revenue (RSM) grew by 11.2%, YoY reaching R$ 21,780 million in the fiscal year ended December 31, 2023. ARPU reached R$ 29.5 in 2023, representing an increase of 13.1%. This result once again reinforces TIM's focus on seeking greater monetization of its customer base in line with its strategy.

Below is a performance breakdown of each mobile customer profile in 2023:

(i)

Prepaid Revenue accelerated its growth to 10.5% YoY in 2023, driven by a more rational environment and the arrival of revenue from Oi Mobile customers. In this context, annual ARPU expanded 12.5% YoY.

(ii)

Postpaid Revenue increased by 11.8% YoY and ARPU grew by 13.6% YoY in 2023. This performance is explained by the following: (i) changes in offers and tariff adjustments on a relevant portion of the Postpaid customer base, impacting the Control plan as of April and other plans as of May; (ii) a positive performance from customers migrating to plans with higher value; and (iii) an improvement in the management of the Company’s customer base, offering better services and controlling and reducing churn rates.

2023 MANAGEMENT REPORT AND EARNINGS ANALYSIS

Interconnection Revenue (ITX) decreased by 5.5% YoY, as a result of lower incoming traffic during the period.

Customer Platform Revenue totaled 162 million in 2023, which had an expected slowdown as a result of the review of the business model of this line, whose strategy continues to be the implementation of new partnerships with exclusive offers – such as the agreement with “Cartão de Todos”, during the second half of the year.

The Other Revenues line recorded an annual growth of 1.0% YoY, resulting from higher revenues related to network sharing contracts and IoT services.

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

In 2023, Fixed Service Revenue grew by 4.6% YoY.

TIM UltraFibra, the main line for the fixed segment, sustained its growth pace of 9.7% YoY in 2023 and ARPU reached R$94.0.

7.2. Operating Costs and Expenses

2023 MANAGEMENT REPORT AND EARNINGS ANALYSIS

Operating Costs and Expenses reached R$ 12,214 million in 2023, a 6.5% increase YoY, reflects an increase in expenses with interconnection lines, mainly driven by international roaming services, and by higher costs with products sold and other factors, such as: (i) higher personnel costs from salary and benefits adjustments and employee profit sharing; and (ii) higher expenses related to civil and tax contingencies.

Breakdown of Costs and Expenses Performance:

The Personnel line reached R$ 1,380 million in 2023, accounting for an increase of 7.9% in the annual comparison. This is explained by: (i) the impact from adjustments on salary, benefits and social charges in the year and (ii) the provisions for expenses related to employee profit sharing in the Company's results.

In 2023, the Commercialization and Advertising line remained stable (+0.1% YoY) when compared to 2022, impacted by TSA expenses from January to April, but benefited with the recognition of Fistel credits in 2Q23.

In 2023, growth in the Network and Interconnection line reached +10.2% YoY. This result indicates a worsening in the Interconnection line, which continues to be affected by: (i) higher expenses with international roaming services with the inclusion of new packages in postpaid offers (reflecting the increase in traffic volume); and (ii) higher expenses with VAS content providers (reflecting the improvement in offers), as well as higher network maintenance costs, and infrastructure sharing contracts.

General and Administrative Expenses (G&A) recorded a drop of 1.2%, compared to 2022, totaling R$896 million. This reduction is mainly explained by: (i) lower expenses related to specialized services; and (ii) a reduction in fine line. These effects were counterbalanced by an increase in Maintenance Services line.

The Cost of Goods Sold (COGS) totaled R$ 1,034 million, an increase of 18.7% YoY, due to TIM’s efforts in retaining its customers and improving their loyalty, in addition to the Company’s strategy to focus on higher-value handsets. This growth was with the growth recorded for Product Revenues during the year.

Provisions for Doubtful Debts (PDD) ended 2023 reaching R$ 640 million, an increase of 2.2% in the annual comparison, due to a larger post-payment base because of the addition of customers from Oi, in addition to the replacement of one of the collection operators.

Other Operating Expenses (Income) totaled R$ 332 million in expenses, increasing the balance of this line when compared to the year 2022. This movement is explained by the non-recurring effect from the accounting for the closing price adjustment agreement for Oi's mobile assets.

2023 MANAGEMENT REPORT AND EARNINGS ANALYSIS

7.3. From EBITDA to Net Profit

Adjusted EBITDA (Earnings Before Interest, Taxes, Depreciation, Amortization and Equity in Earnings)

The Adjusted EBITDA at the end of 2023 totaled R$ 11,620 million, a 15.4% increase YoY with the performance of Mobile Services Revenue as the main lever. The Adjusted EBITDA Margin ended 2023 at 48.8%, increasing the result obtained in 2022 by 2.0 p.p.

Depreciation and amortization (D&A) / EBIT

The D&A line accumulated R$ 7,117 million, an increase of 4.2% compared to 2022, It is worth noting that this line was affected in part of the year by the impact of the acquisition of Oi's mobile assets.

2023 MANAGEMENT REPORT AND EARNINGS ANALYSIS

EBIT closed the year 2023 with a total of R$ 4,717 million, a 49.3% increase compared to the end of 2022, reflecting the consistent evolution of the EBITDA.

Net Financial Result

The Net Financial Result reached a 6.6% increase YoY, totaling a negative result of R$ 1,533 million, This performance is mainly explained by: (i) a higher monetary update on interest related to the 5G auction with the payment of a new installment in December; (ii) the end of interest capitalization on the 3.5GHz license; and (iii) negative impact since in 4Q23 we did not have a new tranche of the C6 subscription bonus, in addition to a negative effect of greater monetary restatement on provisions for contingencies in the civil and tax spheres, in parallel with a lower receipt interest on financial investments with the reduction of the basic interest rate in the country.

Income tax and social contribution

Income Tax and Social Contribution totaled -R$ 347 million in 2023, compared to -R$ 50 million in 2022. This increase was primarily due to the positive impact on net income resulting from the effect on the result generated from the accounting for the closing price adjustment agreement for Oi's mobile assets.

Net Income

Net Income totaled R$2,837 million in 2023, compared to R$1,671 million in 2022. This result represented an expansion of 69.8% YoY, maintaining the excellent growth pace recorded during the year.

7.4. Cash flow, Debt and CAPEX

In 2023, OFCF totaled R$4,490 million, an improvement by R$3,181 million in relation to the previous year. This result is a consequence of strong growth in Normalized EBITDA (-) Capex, together with a more positive variation in Working Capital and Income Tax. This variation is explained by: (i) write-off of the judicial deposit that represents the end of the dispute over the adjustment of the closing price of Oi Móvel with other possible impacts being adjusted in the consideration for the acquisition of Cozani and adjustment relating to the installment received and (ii) due to an effect on the supplier line due to the natural seasonality of the fourth quarter. Furthermore, a lower cash disbursement with the obligations of the 5G auction contributed to this result.

2023 MANAGEMENT REPORT AND EARNINGS ANALYSIS

Net cash generated by operational activities was positive at R$12,421 million, representing an increase of 35.6% compared to the 2022 financial year. Result of a good operational performance represented by Revenue and EBITDA. The improvement in the annual comparison is due to the high disbursement made in 2022, referring to frequency auctions.

Net cash invested in investment activities was negative at R$4,684 million, a reduction of 43.9% in the annual comparison, whose comparative basis reflects the payment for the assets acquired from Oi Móvel in the previous year.

Net cash invested in financing activities in 2023 recorded a negative R$7,208 million, representing a worsening of 106.6% compared to the previous year. Impacted by a greater distribution of earnings throughout the year, including a payment of additional dividends for the year 2022, which was deliberated and carried out in the year 2023.

CAPEX

In 2023, Capex totaled R$ 4,504 million decreasing by 4.8% YoY, already showing the first benefits arising from the efficiency brought by 5G technology.

Debt by Maturity

2023 MANAGEMENT REPORT AND EARNINGS ANALYSIS

Total Debt (post-hedge) amounted to R$16,679 million at the end of 2023, reducing by R$1,896 million over 2022. This reduction reflects: (i) payment of a portion of the short-term financial debt; and (ii) reduction in total leasing, partly due to the sites decommissioning process.

Financing (post-hedge) totaled R$3,705 million in the year. The average cost of debt, excluding leases and licenses related to the 5G auction, was 12.7% p.a. (104.2% of the CDI) in the quarter, lower than the cost of 14.2% p.a. (103.7% of the CDI) in the previous year, reflecting the reduction in the CDI rate in the period.

The Cash and Securities balance totaled R$5,036 million in 2023, corresponding to an increase of R$297 million against 2022. This increase in explained by the strong operating cash generation in the period, with the expansion of Normalized EBITDA (-) Capex during the year, even though it was impacted by the following disbursements: (ii) payments of financial debt; (ii) payments of installments related to the acquisition of 5G frequencies (two EACE installments were paid – in April and October 2023 – and the 5G license for the current year was paid in December 2023); and (iii) payments on accrued leases.

The average financial yield reached 12.5% p.a. (103.2% of the CDI) in 2023, declining by 14.2 p.p. from 2022 due to a lower Selic rate in the annual comparison.

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 December 31, 2023 (66.59% on December 31, 2022).

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

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

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

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

1.2. Corporate Reorganization

1.2.1. Business combination - Cozani

On April 14, 2022, TIM, Telefônica Brasil S.A. and Claro S.A. (“Buyers”) delivered to Oi Móvel S.A. – Under court-ordered reorganization (“Seller”, “Assignor” or “Oi Móvel”) the closing notification regarding the process of acquisition of the Seller’s mobile assets, based on the approvals by the Administrative Council for Economic Defense (CADE), upon signature of an Agreement on Control of Concentrations, whose decision has already become final and unappealable, and by the National Telecommunications Agency (ANATEL), particularly with the publication of Acts 4.949/2022, 4.950/2022 and 4.951/2022, in addition to meeting or waived by the Buyers, as the case may be, all precedent contractual conditions.

TIM S.A.

NOTES TO THE FINANCIAL STATEMENTS

December 31, 2023

(In thousands of reais, unless otherwise indicated)

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

It is worth mentioning that, among them, on April 19, 2022, TIM made the Product Reference Offer available in the ROAMING wholesale market (“ORPA – National Roaming”), which after the adjustments determined by the Technical Area of Anatel, was submitted to the Wholesale Offer Negotiation System – SNOA, and such submission was approved on September 21, 2022.

Some aspects of the Roaming ORPA were subject to Appeals, which have already been considered by Anatel’s Board of Directors. Thus, TIM made the necessary adjustments, so that there was a statement of conditioning corresponding to the submission of said Offer on November 22, 2023.

Also, on April 19, 2022, TIM made the Reference Offer for Mobile Virtual Network Operators (“Reference Offer – MVNO”) available, which was approved by Anatel on September 26, 2022. Some of the terms of this Offer equally were subject to Appeals, which have already been judged by Anatel’s Board of Directors. Likewise, after making the determined adjustments, the Agency certified compliance with the conditions corresponding to the submission of said Offer on November 9, 2023.

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

On July 5, 2022, TIM and Oi Móvel signed a Letter of Intent to guarantee the maintenance and continuity of the mobile services provided at the Comandante Ferraz Antarctic Station (EACF) until the end of the term on February 21, 2024 of Cooperation Agreement 12.000/2019-001/00, signed on February 21, 2019 by the Federal Government, through the Navy Command, and by Telemar Norte Leste and Oi Móvel at the time. The signing arrangements for the First Amendment to said Cooperation Agreement, which formalizes the result of said negotiations, were concluded on December 9, 2022. On June 6, 2023, through Order 115/2023/COGE/SCO, Anatel certified the fulfillment of said determination. On October 18, 2023, the Second Addendum to the aforementioned Cooperation Agreement was signed, since the merger of Cozani by TIM S/A. has regulatory and contractual obligations only until February 21, 2024, and the parties may negotiate the postponement of the contract if there is mutual interest.

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

On October 20, 2022, TIM published Offers aimed at enabling the execution of an Industrial Network Exploration Agreement (“Offer – Industrial Network Exploration”) and Temporary and Onerous Assignment of Rights of Use of Radiofrequency (“Offer – Radiofrequency”), under the terms defined by the ACC (Agreement on Control of Concentrations) signed with CADE. The offers in question were published on TIM’s website and presented to CADE on the same date, within the period established by the ACC (up to 6 months from Closing), and should be available for 36 months.

On December 20, 2022, TIM published offers intended to enable the signing of a Contract for the Temporary and Onerous Assignment of Rights of Use of the 900 MHz Radiofrequency, having as its object the radio frequencies acquired from Oi Móvel in said frequency band (“Offer – 900 MHz Radiofrequency”) under the terms set forth by the ACC entered into with CADE. The offers in question were published on TIM’s website and presented to CADE on the same date, within the period established by the ACC (up to 8 months from Closing), and should be available for 36 months.

The ACC is waiting a certificate of compliance from CADE.

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.

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 reais 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.

NOTES TO THE FINANCIAL STATEMENTS

(In thousands of reais, unless otherwise indicated)

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 reduction in the consideration was recorded in the profit for the year on the date of approval of the agreement, under “other operating revenues (expenses)”, as disclosed in Note 30.

The amount corresponding to half the amount deposited in court was recorded under “other operating revenues (expenses)”, as disclosed in Note 30.

On December 31, 2023, considering the agreement signed with Oi S.A., the Company was free from any obligations mentioned in items (i) and (ii). On December 31, 2022, the amount of such obligations was R$ 748 million.

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.

TIM S.A.

(In thousands of reais, unless otherwise indicated)

General criteria for preparation and disclosure

The individual and consolidated financial statements were prepared considering the historical cost as value basis, except regarding the derivative financial instruments that were measured at fair value.

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

The Company had a profit of R$ 2,837,422 on December 31, 2023. The Company’s current liabilities exceeded total current assets by R$ 1,485,561, caused by the acquisition of Cozani and payment of obligations related to the 5G license; however, the cash flow increased by approximately R$ 1.2 billion in 2023. The Company understands that the aforementioned investments will bring relevant benefits and operational efficiency. On December 31, 2023, the Company’s shareholders’ equity is positive by R$ 26,015,940.

In connection with the preparation of these financial statements, Company’s Management made analyses which confirms that the operating cash flow is positive by R$ 12 billion; therefore, there is no evidence of uncertainties about the going concern.

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

Interests paid 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 financial statements 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.

TIM S.A.

NOTES TO THE FINANCIAL STATEMENTS

December 31, 2023

(In thousands of reais, unless otherwise indicated)

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

Due to the merger of Cozani on April 1, 2023 described in Note 1, the Company incorporated all asset and liability balances of its former parent company and presents consolidated balances for the statements of income, statements of comprehensive income, statements of cash flows and statements of value added due to Cozani’s individual statements of income for the period January−March 2023 making up the consolidated balances throughout 2023.

Business combination and goodwill

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

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

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

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

TIM S.A.

NOTES TO THE FINANCIAL STATEMENTS

December 31, 2023

(In thousands of reais, unless otherwise indicated)

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 financial statements

These individual and consolidated financial statements were approved by the Board of Directors of the Company on February 6, 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 year ended December 31, 2023 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 did not have an impact on the consolidated financial statements of the Group.

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 financial statements.

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

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

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

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.

Changes did not affect the consolidated financial statements of the Group.

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

(In thousands of reais, unless otherwise indicated)

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.

Changes did not affect the consolidated financial statements of the Group.

The following new standards were issued by the Accounting Pronouncement Committee (“CPC”) and International Accounting Standards Board (IASB), but are not effective for the year ended December 31, 2023.

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 financial statements.

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

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

What is meant by the right to postpone settlement.

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

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

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

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

TIM S.A.

NOTES TO THE FINANCIAL STATEMENTS

December 31, 2023

(In thousands of reais, unless otherwise indicated)

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

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

Supplier financing agreements - Amendments to IAS 7 and IFRS 7

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

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

The Company is assessing the impacts to ensure that all information complies with the standard as of its effective date.

(h) Restatement of statements of cash flows

As a result of the continuous review of the cash flow and preparation of financial information for disclosure and with the purpose of ensuring greater compliance with accounting standards, Management identified the reclassification below applicable to the Company's statements of cash flows as of December 31, 2022 .

We have identified that interest received from financial investments was fully classified as investment activities. Nevertheless, according to IAS 7/CPC 03, interest received can be classified as operating activities, as they are considered a source of operating income

This adjustment aims to more adequately reflect the operational nature of such interest in the presentation of the Company's statements of cash flows.

This restatement does not change the statement of income, balance sheet position or total net cash flow for the year ended December 31, 2022. The restatement only changes the classification between the categories of operating and investment activities, providing a more accurate view of the Company's operating cash generation and is presented as follows:

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

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

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).

(b) Provision for legal and tax administrative proceedings

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

(c) Fair value of derivatives and other financial instruments

The financial instruments presented in the balance sheet at fair value are measured using valuation techniques that consider observable data or observable data derived from market (note 37).

(d) Unbilled revenues

Since some cut dates for billing occur at intermediate dates within the months of the year, as the end of each month there are revenues earned by the Company, but not actually invoiced to its customers. These unbilled revenues are recorded based on estimate that takes into consideration historical consumption data, number of days elapsed since the last billing date, among others (note 28).

(e) Leases

The Company has a significant number of the lease contracts in which it acts a lessee (Note 17), and with the adoption of the accounting standard IFRS 16 / CPC 06 (R2) – Leases, on January 1, 2019, certain judgments were exercised by Company’s management in measuring lease liabilities and right-of-use assets, such as: (i) estimate of the lease term, considering non-cancellable period and the period covered by options to extend the contract term, when the exercise depends only from the Company, and this exercise is reasonably certain; and (ii) using certain assumptions to calculate the discount rate.

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

Trade accounts receivable

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

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

The fair value of trade accounts receivable is close to the book value recorded on December 31, 2023 and December 31, 2022.

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

In September 2021, the Federal Supreme Court (STF), with general repercussions, established an understanding for the non-levy of Corporate Income Tax (IRPJ) and Social Contribution (CSLL) on the monetary restatement using the SELIC rate in cases of undue payment. At that time, TIM recorded its best estimate, in the amount of R$ 535 million (principal). Over the years, there has been recognition of the inflation adjustment in the amounts of R$ 11 million in 2021, R$ 61 million in 2022, and R$ 41 million in 2023.

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

Thus, the company carried out the reclassification between asset accounts (Recoverable income tax and social contribution x Deferred income tax and social contribution) amounting R$ 156 million, recognizing deferred taxes on tax losses and negative CSLL basis in the amounts of R$ 114 million and R$ 42 million, respectively. The amount of R$ 470 million that was reclassified from non-current to current remained in recoverable IRPJ and CSLL accounts. A write-off of R$ 13 million was made in the third quarter of 2023 to adjust the amount recorded in the third quarter of 2021. During the third quarter of 2023, the Company started using such tax credits to offset current PIS and COFINS debits and other federal taxes. Since the 3Q23, the Company used the amount of R$ 151 million.

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 financial statements. Deferred income tax is determined using the tax rates (and tax laws) enacted, or substantially enacted, up to the balance sheet date. Subsequent changes in tax rates or tax legislation may modify the deferred tax credit and debit balances.

Deferred tax assets on income tax and social contribution are recognized only in the event of a profitable track record and/or when the annual forecasts prepared by the Company.

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 December 31, 2023 and 2022, the rates in force 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:

(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$ 891 million until December 31, 2023 (R$ 663 million up to December 31, 2022) and applied on January 1, 2020.

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

(v) Represents the deferred charges recorded, referring to the impairment of tangible assets acquired in the Cozani’s acquisition in April 2022.

Expected recovery of tax credits

The estimates of recoverability of tax credits were calculated taking into consideration financial and business assumptions available on December 31, 2023.

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 expenses	Total
2024	201,227	694,157	895,384
2025	-	197,399	197,399

>2027	-	1,953,416	1,953,416
Total	201,227	3,004,587	3,205,814

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

The Company used credits from tax losses and the negative basis of social contribution in the amount of R$ 105,299 throughout 2023 (R$ 123,948 in 2022).

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 December 31, 2023.

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

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

Property, plant and equipment

Property, plant and equipment are measured at acquisition and/or construction cost, less accumulated depreciation and impairment losses (the latter only if applicable). Depreciation is calculated based on the straight-line method over terms that consider the expected useful lives of the assets and their residual values. The amounts of property, plant and equipment recorded on Cozani’s acquisition were adjusted to its recoverable amounts and after the merger are recorded at TIM S.A. On December 31, 2023 and December 31, 2022, 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.

NOTES TO THE FINANCIAL STATEMENTS

(In thousands of reais, unless otherwise indicated)

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. This capitalization occurred when the asset was considered available for use by Management. As of the second quarter of 2023, the capitalization of interest and charges on this asset ended. These costs are amortized over the estimated useful lives.

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

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

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

(d) Goodwill registered

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

Goodwill on the acquisition of Cozani

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

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

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

NOTES TO THE FINANCIAL STATEMENTS

(In thousands of reais, unless otherwise indicated)

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 December 31, 2023 and December 31, 2022.

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

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

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:

TIM S.A.

NOTES TO THE FINANCIAL STATEMENTS

December 31, 2023

(In thousands of reais, unless otherwise indicated)

The Management of the Company understands that the smallest unit generating cash for impairment testing of goodwill in the acquisition of the companies previously described covers TIM S.A., Tim Group’s operating company in Brazil and that in 2023 merged Cozani’s balances, acquired in 2022. This methodology is aligned with the company's strategic direction. It is worth highlighting that the group’s results are mainly represented by TIM S.A., but since the merger of Cozani occurred on April 1, 2023, these results impacted the consolidated TIM S.A. until March 31, 2023.

On December 31, 2022, the impairment test was performed by comparing the book value with the fair value minus the disposal costs of the asset, as foreseen in IAS 36 / CPC 01.

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

The fair value of 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.

In 2023, the measurement was made based on the value of the share at the balance sheet closing date and sensitivity tests were also performed and in none of the scenarios was identified any indication of impairment, being the fair value determined higher than the book value. Therefore, being the fair value higher than the book value, it is not necessary to calculate the value in use. Therefore, the calculations carried out at the consolidated level essentially contemplate the results and accounting balances of TIM S.A., so the management of the Company concludes that the use of the fair value less of cost of sales methodology is adequate to conclude that there is no provision for impairment since the fair value less the cost of sales is higher than the total book value of the cash generating unit.

On December 31, 2023, the Company carried out the analysis of all tangible, intangible assets and investments and did not identify any impairment indicators.

(e) Infrastructure right-of-use - LT Amazonas

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

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

(f) Authorizations

4G License

In this item are recorded the values related to the acquisition of Lot 2 in the auction of the 700 MHz band in the amount of R$ 1,739 million, in addition to the costs related to the cleaning of the frequency of the 700 MHZ band acquired, which totaled R$ 1,199 million, in nominal values. As it is a long-term obligation, the amount payable of R$ 1,199 million was reduced by R$ 47 million by applying the concept of adjustment to present value (“AVP”). The aforementioned license fell under the concept of qualifying asset. Consequently, the financial charges on resources raised without a specific destination, used for the purpose of obtaining a qualifying asset, were capitalized between the years 2014 and 2019.

5G License

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

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

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

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

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.

(In thousands of reais, unless otherwise indicated)

Furthermore, as described above, the Company capitalizes loan costs for qualifying assets that require a substantial period of time to be in a condition for use as intended by Management. This concept includes the 3.5GHz radio frequency. On December 31, 2023, the Company recorded R$ 95 million in intangible assets referring to interest calculated based on the Selic rate (R$ 259 million in 2022) incurred on the 3.5GHz radio frequency and did not capitalize the inflation adjustments of amounts due to EAF in 2023 since there is no further balance to disburse with this entity (R$ 99 million in 2022). These balances were recorded as goods in progress until the asset was available for the use intended by Management. 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 total effect on the Company’s intangible assets on December 31, 2023 referring to 5G radio frequencies and related obligations was R$ 3,930 million (R$ 3,866 million in 2022) and there are no more balances of assets in progress relating to 5G licenses on December 31, 2023 (R$ 2,753 million in 2022) and R$ 3,930 million in Authorizations (R$ 1,113 million in 2022).

Leases

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

Leases whose the Company is a lessee are capitalized at the lease's commencement at the lower of the fair value of the leased asset (right-of-use) and the present value of payments provided for in contract, and lease liability as a counterparty. Interest related to the leases is taken to income as financial costs over the term of the contract.

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

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

ii) Sale and leaseback of Towers

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

In total, 5,873 towers were transferred, being 54,336 and 5,483 in the years 2017, 2016 and 2015, respectively. This transaction resulted in a sales amount of R$ 2,651,247, of which R$ 1,088,390 was booked as deferred revenue and will be amortized over the period of the contract (Note 23).

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

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

(iv) Other leases:

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

The present value, principal and interest value on December 31, 2023 for the above contracts was estimated month-to-month, based on the average incremental rate of the Company’s loans, namely 13.63% (13.24% in 2022).

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

The lease amounts considered low-value or short-term (less than 12 months) were recognized as rental expenses and totaled R$ 32,037 on December 31, 2023 (R$ 40,723 on December 31, 2022).

18.

Other amounts recoverable

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

On December 31, 2023, this credit is R$ 80,963 (R$ 26,519 on December 31, 2022).

19.

Suppliers

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

After carrying out the operations, the Company currently has the banks as creditors of the notes assigned by the suppliers in the original value and term of the assigned credit rights, without any associated financial charge or benefit. Trade notes payable related to these operations remain classified under “suppliers”. On December 31, 2023, the Company has approximately R$ 316 million (R$ 260 million on December 31, 2022) related to the drawee risk operation.

In December 2021, the Terms of Authorization were signed, characterizing the actual acquisition of the right over the lots of these radio frequencies.

For the amounts related to radio frequencies (R$ 884 million upon initial registration), Selic rate interest is levied, and the Company will make annual payments for a period of 20 years (the three first installments were paid in the amounts of R$ 46,274, R$ 52,005 and R$ 57,811). Regarding amounts related to disbursement obligations with EAF and EACE entities (R$ 2,737 million upon initial registration, of which R$ 2,654 million net of adjustment do present value), there is a monetary restatement by IGP-DI, and disbursements will occur until 2024. The contributions to EAF were fully made in 2022 (R$ 1,090 million in February and R$ 1,133 million in May). Regarding EACE, four contributions totaling R$ 533 million were made up until December 31, 2023.

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 the operations on December 31, 2023 is, respectively, R$ 478,098, R$ 520,990, R$ 1,821,869, R$ 381,027 and R$ 193,878 (in 2022 was respectively, R$ 1,519,742, R$ 59,199, R$ 1,670,839, R$ 361,828 and R$ 219,697).

(In thousands of reais, unless otherwise indicated)

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, reduction of Complaint Rates, repair of users and strengthening of transport and access networks, among others. In addition, it contemplates the additional commitment to bring mobile broadband, through the 4G network, to 350 municipalities with less than 30 thousand inhabitants thus reaching more than 3.4 million people. The new infrastructure was implemented in less than three years – more than 99% of the municipalities were served in the first two years and with the Company guaranteeing the sharing regime with the other operators. The service for 350 municipalities was certified by Anatel in June 2023.

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

In June 2022, TIM concluded the 2^nd year of the Conduct Adjustment Term (TAC) entered into with Anatel, having carried out the activities planned for strict compliance with the purpose of achieving the associated targets. The following commitments were certified by Anatel: Numbering; Impediment; Internal controls; LTE 700 MHz; New 4G; Backhaul; Personal assistance; Digital relationship; Additional; and Collaborative Portal.

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

In June 2023, TIM concluded the 3^rd year of the Conduct Adjustment Term (TAC) entered into with Anatel, having carried out the activities planned for strict compliance with the purpose of achieving the associated targets. Regarding the Additional Commitments, as aforementioned, Anatel has already issued a statement of fulfillment of the obligation relating to the third year of the TAC, thus guaranteeing the general statement of fulfillment of the obligation for the implementation of SMP with 4G or later technology in 350 (three hundred and fifty) municipalities under the terms agreed in the TAC. In December 2023, the following Commitments were attested: Numbering; Impediment; Repair Plan; Internal controls; LTE 700 MHz; New 4G; Backhaul; Digital relationship. Anatel indicated that: (i) it is still evaluating compliance with the commitment related to Station Licensing and IQP; and (ii) in relation to the Reparation Plan commitment (for 10 records only) and IR would establish PADICs.

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

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

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

The balances recorded under these items represent the Company's expenses related to the long-term incentive program granted to employees (note 27).

c. Profit reserves

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

c. 3 Tax Benefit Reserve

The Company enjoys tax benefits that provide for restrictions on the distribution of profits. According to the legislation that establishes these tax benefits, the amount of tax that is no longer paid due to exemptions and reductions in the tax burden may not be distributed to members and will constitute a reserve of tax incentive of the legal entity. This reserve can only be used to offset losses or increase share capital. On December 31, 2023, the accumulated amount of benefits enjoyed by the Company amounts to R$ 2,362,239 (R$ 2,124,411 on December 31, 2022).

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

Dividends are calculated in accordance with the bylaws and the Joint Stock Company Act.

According to its latest bylaws, approved on August 31, 2020, the company must distribute as a mandatory dividend each year ending December 31, provided that there are amounts available for distribution, an amount equivalent to 25% of Adjusted Net Profit.

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

On December 31, 2023 and 2022, dividends and interest on shareholders' equity were calculated as follows:

	2023	2022

Net profit for the year	2,837,422	1,670,755
(-) Non-distributable tax incentives	(237,828)	(166,110)
(-) Constitution of legal reserve	(129,979)	(75,233)
Adjusted net profit	2,469,615	1,429,412

Minimum dividends calculated on the basis of 25% of adjusted profit	617,404	357,353

Breakdown of dividends payable interest on shareholders’ equity:
Interest on shareholders’ equity	1,600,000	1,400,000
Total dividends and interest on shareholders’ equity distributed and proposed	1,600,000	1,400,000

Withholding income tax (IRRF) on interest on shareholders' equity	(233,230)	(196,970)
Total dividends and interest on shareholders’ equity, net	1,366,770	1,203,030

Interest on Shareholders' Equity paid and/or payable is accounted for against financial expenses which, for the purposes of presenting the financial statements, are reclassified and disclosed as allocation of net profit for the year, in changes in shareholders' equity.

During the year 2023, the amount of R$ 1,600,000 of interest on shareholders’ equity were distributed and additional amount of R$ 1,310,000 of dividends were proposed, which are subject to approval during the General Meeting on March 28, 2024, totaling R$ 2,910,000.

Net revenue

Revenues from services rendered

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

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

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

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

The net service revenue item also includes revenue from new partnership agreements (financial, education and advertising), and the amount of revenue recognized in the year ended December 31, 2023 is R$ 162,122 (R$ 153,348 on December 31, 2022).

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

Revenues from sales of goods

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

Contract identification

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

Identification of the performance obligation

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

(i) sale of equipment; and

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

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

Determining and Allocating the Transaction Price to the Performance Obligation

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

Cost to obtain contract

All incremental costs related to obtaining a contract (sales commissions and other costs of acquisition from third parties) are recorded as prepaid expenses and (as described in Note 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.

Derivatives are initially recognized at fair value on the date the derivative agreement is entered into, and are subsequently remeasured at fair value. The Company does not apply “hedge accounting”.

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

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

The main risk factors to which the Company is exposed are:

(i) Exchange rate risks

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

On December 31, 2023 and December 31, 2022, the Company's loans and financings indexed to the variation of foreign currencies are fully protected, both in terms and in value, by swap contracts. Gains or losses on these swap contracts are recorded in the company's earnings.

(ii) Interest rate risks

Interest rate risks 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 and the exposure to a fixed rate linked to the debt with BNP Paribas, all of them until maturity.

The possibility of an unfavorable movement in interest rates would cause an increase in the financial expenses of the Company, as a result of the share of the debt and the passive positions that the Company has in swap contracts linked to floating interest rates (percentage of the CDI). However, on December 31, 2023 and December 31, 2022, the Company maintains its financial resources applied to Interbank Certificates of Deposit (CDI), which substantially reduces this risk.

NOTES TO THE FINANCIAL STATEMENTS

(In thousands of reais, unless otherwise indicated)

(iii) Credit risk inherent in the provision of services

The risk is related to the possibility of the company computing losses derived from the inability of the subscribers to honor the payments of the invoiced amounts. To minimize this risk, the company preventively performs credit analysis of all orders imputed by the sales areas and monitors the accounts receivable of subscribers, blocking the ability to use services, among other actions, if customers do not pay their debts. There are no customers who have contributed more than 10% of net accounts receivable on December 31, 2023 and December 31, 2022 or revenues from services rendered during the years ended December 31, 2023 and December 31, 2022.

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

The group's policy for the sale of telephone devices and the distribution of prepaid telephone cards is directly related to the credit risk levels accepted during the normal course of business. The selection of partners, the diversification of the portfolio of accounts receivable, the monitoring of loan conditions, the positions and limits of orders established for traders, the formation of collateral are procedures adopted by the company to minimize possible collection problems with its trading partners. There are no customers who contributed more than 10% of revenues from sale of goods during the years ended December 31, 2023 and 2022. There are no customers who contributed more than 10% of the net accounts receivable from the sale of goods on December 31, 2023 and December 31, 2022.

(v) Liquidity risk

Liquidity risk arises from the need for cash before the obligations assumed. The Company structures the maturities of its non-derivative financial instruments and their respective derivative financial instruments so as not to affect liquidity. See Notes 17 and 21.

The liquidity and cash flow management of the Company are carried out daily to ensure that the operational cash generation and prior fund raising, when necessary, are sufficient to maintain its schedule of operational and financial commitments.

All 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.

Other derivatives are instruments of share subscription options represent the option of the Company to subscribe 4.44% of the shares of C6 capital on December 31, 2023 (5.52% on December 31, 2022), where the Group/Company paid a share subscription premium in the amount of R$ 25.5 million until December 31, 2023 (R$ 23.9 million until December 31, 2022). As required by IFRS 9 / CPC 48, the financial instrument must be valued at its fair value that on December 31, 2023 and December 31, 2022 corresponds to R$ 502 million and R$ 625 million, respectively. The change for the period refers to the achievement of 2 targets in 2023 (9^th and 10^th targets), with a fair value of R$ 40.7 million and subscription and shares in the amount of R$ 163 million, according to Note 12.

The impact of the mark-to-market is calculated by the difference in the fair value of the option less the amount paid for the share subscription premium. This financial instrument was measured at fair value and subsequently revaluated and possible changes recorded in the Company’s financial income (loss) for the year, considering the arbitration risks disclosed in Note 28.

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

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

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

Specific evaluation techniques used to measure the financial instruments include:

Quoted market prices or quotes from financial institutions or brokerage firms for similar instruments.

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

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

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

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 December 31, 2023, there are no margins or guarantees applied to transactions with derivative financial instruments of the Company.

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

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

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

The operations with derivative financial instruments contracted by the company and in force on December 31, 2023 and December 31, 2022 are shown in the following table:

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

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

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

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

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

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

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

The sensitivity analyses for derivative financial instruments in force on December 31, 2023 were carried out considering, basically, the assumptions related to changes in market interest rates and the change in the US dollar used in swap contracts. The use of these assumptions in the analysis is due exclusively to the characteristics of derivative financial instruments, which have exposure only to changes in interest and exchange rates.

3. Items discussed with the Independent Auditors considering the Audit Report (ISA 701) presentation form
