INDEPENDENT AUDITOR’S REPORT ON THE INDIVIDUAL AND CONSOLIDATED FINANCIAL STATEMENTS

 

 

 

To the

Shareholders and Management of

Companhia de Saneamento Básico do Estado de São Paulo - SABESP

São Paulo - SP

 

 

 

Opinion

 

We have audited the individual and consolidated financial statements of Companhia de Saneamento Básico do Estado de São Paulo - SABESP (“Company”), identified as parent company and consolidated, respectively, which comprise the statement of financial position as at December 31, 2023, and the respective statements of income, comprehensive income, changes in equity and cash flows for the year then ended, as well as the corresponding notes to the financial statements, including material accounting policies and other explanatory information.

 

In our opinion, the accompanying financial statements present fairly, in all material respects, the Company’s individual and consolidated financial position as at December 31, 2023, its individual and consolidated financial performance and its individual and consolidated cash flows for the year then ended in accordance with Brazilian accounting practices and International Financial Reporting Standards (IFRSs) issued by the International Accounting Standards Board (IASB).

 

 

Basis for opinion

 

We conducted our audit in accordance with Brazilian and International Standards on Auditing (ISAs). 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 controlled company in accordance with the relevant ethical principles established in the Code of Ethics for Professional Accountants and in the professional standards issued by the Brazilian Federal Council of Accounting (CFC), and we have fulfilled our other ethical responsibilities in accordance with these standards. We believe that the audit evidence obtained is sufficient and appropriate to provide a basis for our opinion.

 

 

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 for the current year. 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, accordingly, we do not provide a separate opinion on them.

 

 

Other matters

 

Audit of prior period

 

The financial statements of the Company for the year ended December 31, 2022, were audited by other independent auditor, whose report thereon, dated March 23, 2023, was unmodified.

 

Statements of value added

 

The individual and consolidated statements of value added for the year ended December 31, 2023, prepared under the responsibility of the Company’s Management and presented as supplementary information for IFRS purposes, were submitted to the same audit procedures followed for the audit of the Company’s financial statements. In order to form an opinion, we have checked whether these statements are reconciled with the financial statements and accounting records as applicable, and whether its form and contents meet the criteria established in Technical Pronouncement CPC NBC TG 09 - Statement of Value Added. In our opinion, the statements of value added were properly prepared, in all material respects, in accordance with the criteria established in that Technical Pronouncement and are consistent with the individual and consolidated financial statements taken as a whole.

 

 

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

 

The Company’s Management is responsible for the other information that comprises 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 audit 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 the 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 this 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 individual and consolidated financial statements

 

Management is responsible for the preparation and fair presentation of the individual and consolidated financial statements in accordance with Brazilian accounting practices and the IFRS issued by IASB, and for such internal control as management determines is necessary to enable the preparation of financial statements that are free from 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 and its controlled 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 controlled company’s financial reporting process.

 

Auditor’s responsibilities for the audit of the individual and consolidated financial statements

 

Our objectives are to obtain reasonable assurance about whether the individual and consolidated financial statements as a whole are free from 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 (ISA) 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 the referenced financial statements.

 

As part of an audit in accordance with Brazilian standards and ISAs, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

 

§

Identify and assess the risks of material misstatement of the individual and consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain 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 controls;

§

Obtain an understanding of internal controls 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 controlled company’s internal controls;

§

Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and disclosures made by Management;

§

Conclude on the appropriateness of Management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s and its controlled company’s ability to continue as a going concern. If we conclude that 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 and its controlled company to cease to continue as a going concern;

§

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

§

Obtain sufficient and appropriate audit evidence regarding the financial information of the entities or business activities within the group to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the audit. We remain solely responsible for our audit opinion.

 

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal controls that we identify during our audit.

 

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence and communicate to 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 to those charged with governance, we determine those that were of most significance for the audit of the financial statements for the current year and which 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.

 

The accompanying financial statements have been translated into English for the convenience of readers outside Brazil.

2023 MANAGEMENT REPORT

 

 

 

MESSAGE FROM THE CEO

50 years of lives!

2023 was a year of transformation and the creation of new opportunities for all of us.

We celebrated half a century of existence, commemorating past achievements and the prospect of an even more promising future. A future where people and the environment are consolidated at the heart of our strategy, with the universalization of sanitation as a tool to achieve this goal.

Throughout these 50 years, numerous challenges and achievements have led us to become one of the largest sanitation companies in the world, a reference in innovative solutions, and a leader in investment rankings in Brazil. In this period, many things evolved, including ourselves, always connecting with people and reinforcing our commitment to life in all its forms.

In this journey of transformation, our corporate structure has become more modern, agile, and participatory. As a result, we have gained competitiveness and efficiency.

The restructuring brought greater rationality in resource allocation, team integration, process revision, and a vision that we are all part of One Unified Sabesp, an innovative company that uses all means to provide the best service to its customers.

In the context of this new environment, we launched a new visual identity that explores watercolor by mixing colors and liquids that represent sustainability and balance with nature, and also symbolize Sabesp's commitment to innovation, transparency, and efficiency. These light and varied elements were added to the Company’s traditional symbol of ancient amphora, designed in 1973.

A good example of what awaits us with these changes was the award received in a bidding process to operate basic sanitation services in the city of Olímpia (SP), an important milestone in 2023. For the first time, a state-owned company in the sector won a bidding process in Brazil, competing with eight other private bidders.

This victory signals our potential to grow, expand our operations, and broaden the scope of business with environmental solutions, bringing all the concepts of circular economy (biogas and fertilizer production from sewage treatment, water for industrial reuse, and energy efficiency enhancement), contributing to environmental preservation and a more inclusive and fair society.

In addition to the review of existing structures (Operation; Financial and IR; and People and Management), it is worth highlighting the new Offices (Engineering and Innovation; Customers; and Regulation and New Business) aimed at scaling up and enhancing efficiency in our main value drivers. Additionally, we have also created the Superintendence of Sustainability and Corporate Governance and the Superintendence of Digital Transformation, which report directly to me and mirror our commitment to sustainability, operational efficiency, innovation, and technology. Of the seven Offices, three are led by women in addition to the Company's Board of Directors, which is also chaired by a woman.

This Report features the essence of these changes, definitively integrating the ESG agenda as a strategic part of our business.

The expansion process includes involvement in important global agendas. Accordingly, we participated in various local and international forums for sharing experiences, featuring the three panels during the 28th Conference of the Parties (COP28) in Dubai, United Arab Emirates, which confirms the value of our expertise in basic sanitation.

The numbers ratify this value. Our current sanitation rates are among the best in Brazil. We have 98% water supply coverage, 93% sewage collection coverage, and 85% of households connected to sewage treatment. And these percentages will increase. Not only the amount invested in 2023 represented a historical record for the Company, about 85% of the water and sewage Capex for the years 2024 and 2025 is already tendered or has already been contracted.

For the 2024 to 2028 period, our current Multi-Year Investment Plan (disclosed in December) provides for investments of R$ 33.91 billion in system expansion and R$ 11.27 billion in works for improvement, efficiency, and asset renewal.

The IntegraTietê Program, launched in 2023, includes various short-, medium-, and long-term measures to address some of the most vulnerable points of the Tietê River, the largest in the State.

It was a challenging and very productive year and we still have a lot to do. Our numbers are the result of hard work and focus. In addition to the aforementioned record investment, it is worth noticing the conclusion of the Extraordinary Tariff Review, which adjusted distortions in our revenue from previous years, and the financing with sustainability indicators contracted with the IFC (in which the cost of financing is reduced as the Company achieves certain sustainability commitments).

I thank all our employees for their cooperation and aptitude for facing new challenges. I also thank our suppliers, customers, advisors, and shareholders for their support in this transformation process.

 

André Salcedo

CEO

MACROECONOMIC AND SECTOR CONTEXT

The year 2023 marked an economic recovery in Brazil. With controlled inflation, there was room for interest rate decreases, favoring prospects in the credit market. On the external front, challenges and uncertainties due to geopolitical tensions remained as sources of volatility in financial markets.

Despite the more volatile external scenario, the Company reported revenue growth reflecting an improvement in economic indicators. In addition to the broader context, the conclusion of the Annual Adjustment and the Extraordinary Tariff Review, with the approval of a total tariff adjustment of 9.5609% in April 2023, contributed to a positive outcome. Although net margins decreased, mainly due to the impact of the financial result, operational performance significantly increased.

On the cost side, the Company implemented various structural actions aimed at reducing costs and increasing long-term efficiency. Organizational restructuring, modernization, and investment in technology in operations, the creation of the Shared Services Center, and the Incentivized Dismissal Program (IDP) are examples of actions aimed at the Company's sustainability in a more competitive business environment, given the changes in sector legislation.

The approved investments for the 2024-2028 period, totaling R$ 47.4 billion, which now include the IntegraTietê Program, imposed an even more intense pace of investment expansion, focusing on expanding networks and sewage treatment.

In 2023, the Company's response to the new dynamics of the sanitation sector was marked by participation in utilities concession bidding processes. In May, the Company was granted the contract and signed a concession agreement with the Municipality of Olímpia to supply water and provide sewage services for the next 30 years. Through a contractually regulated Special Purpose Entity (SPE), Sabesp will invest in technologies to control water losses and build pipelines, and supply capacity in line with the city's growth, which is known for its thermal water tourism. The actions will benefit more than 56 thousand residents with improved health and quality of life.

Another step towards improving sector regulations was the enactment of State Decree 67,880/2023, which provides for the adherence of Municipalities to their respective Regional Units for Drinking Water Supply and Sanitation Services (URAEs) and their inter-federal governance structures. The decree gives greater effectiveness and representativeness to the Decision-Making Boards of the Regional Units, which will resolve on the signing of contracts, agreements, and partnerships for water supply and sanitation services.

Composed of the municipalities served by Sabesp, under the terms of the New Sanitation Framework (Federal Law 14,026/2020), URAE 1 - Southeast (URAE-1) saw the adhesion of the Municipality of São Paulo in August 2023, representing an important step in its formalization, reinforcing the vision of providing basic sanitation services in a regionalized manner in the São Paulo State.

Privatization Process

As part of the changes observed in the basic sanitation sector in recent years, the São Paulo State Government started the Company’s privatization process, aiming to respond even more promptly and efficiently to the new regulatory reality impacting the sector.

In April 2023, the International Finance Corporation (IFC), an agency linked to the World Bank, was contracted to conduct studies on the Company’s privatization, which indicated a public offering of shares as the best model to be adopted, whose main benefits include (i) adding and advancing investments to achieve universalization goals; and (ii) reducing tariffs by using part of the funds obtained in the transaction.

In September 2023, the São Paulo State informed the municipalities operated by Sabesp about the proposed amendment to the conditions of the current concession agreements, observing the following guidelines (a) advancing the achievement of the universalization goals outlined in the New Legal Sanitation Framework to 2029, subject to any shorter deadlines contractually provided; (b) extending the duration of the concession agreement until 2060; (c) obliging Sabesp to serve the population residing in consolidated informal urban nuclei and rural areas, to cover the entire municipal territory; and (d) detailing the investments to be made in each municipality.

The communication also reaffirmed commitments to increase and advance investments, reduce tariffs, and improve sanitation services, to (a) provide predictability and transparency to the regionalized structure, considering already shared infrastructures; and (b) detail Sabesp's specific obligations regarding each municipality, including coverage goals, main works, and investments.

Following this process, in December 2023, State Law 17,853/2023 was approved, authorizing the privatization of Sabesp, and in February 2024, a public consultation was opened regarding (i) the draft of the Concession Agreement to be signed between URAE-1 and Sabesp, with the indication of the São Paulo State Utility Service Regulatory Agency's role, together with the specific technical exhibits of the municipalities comprising URAE-1, in addition to other contractual exhibits; (ii) the draft of the internal regulations of URAE-1’s Decision-Making Board; and (iii) the draft of the Regional Sanitation Plan, under Article 17 of Federal Law 11,445, of 2007.

Regulation of Services and Tariffs

The New Framework gave the Water National Agency (ANA) the power to issue reference standards containing guidelines for the regulation of public sanitation services in Brazil, which will be exercised by sub-national regulatory agencies after the respective adhesion. In the case of Sabesp, our current contracts are regulated by the São Paulo State Utility Services Regulatory Agency (Arsesp), in line with the terms established in the instruments in force.

In this context, ANA and Arsesp periodically disclose regulatory agendas with matters that should be subject to future regulation. Sabesp actively participates in the discussions held in meeting rounds before taking subsidies and public consultations on the regulatory regulations impacting its business.

Regarding the calculation of tariffs, the current regulatory model adopted by Arsesp establishes a regulation based on incentives, which consists of establishing a maximum tariff (P0) that ensures the economic-financial balance of the service provider in the entire area of operation, taking into consideration the projected efficient costs and the investments to be made in the four-year tariff cycle.

The calculation model is based on a Discounted Cash Flow model, whose objective is to calculate the maximum average tariff (P0), whose reference is the operating costs for the provision of services and the remuneration and recovery of investments made (required revenue), considering the expected market for the four-year period, where the Net Present Value (NPV) of the tariff cycle is equal to zero, taking into consideration a return rate equal to the weighted average cost of capital (WACC).

After establishing the maximum average tariff (P0) in the ordinary tariff review processes, during the tariff cycle, the Agency authorizes the annual tariff adjustment (IRT), which adjusts tariffs based on the variation of the IPCA (consumer price index) in the last 12 months, less a productivity factor to be shared with users (X Factor) plus or less a quality factor (Q Factor). This mechanism aims at allowing the adjustment for inflation and encouraging the Company to continuously pursue efficiency and cost reduction, as well as meet desired quality criteria in providing services to users.

Specifically for the 2021-2024 cycle, compensatory adjustments (AJC) are expected, due to the achievement - or not - of the projected authorized revenue, as well as possible adjustments in other variables (revenue risk limitation ± 2.5%).

Sabesp’s tariff structure consists of a set of rules applied to the Company’s revenue where users are classified into residential, commercial, industrial, and public categories. The structure is based on the Tariff Regulation approved through State Decree 41,446 of 1996, in the legislation, and regulatory rules in force.

Given the need for adjustments for both 2021 and 2022 due to the failure to achieve authorized revenue, in April 2023, Arsesp concluded the Annual Adjustment and Extraordinary Tariff Review processes, authorizing the Company to apply a total tariff adjustment index of 9.5609% compared to the existing tariffs, which came into effect in May 2023.

THE COMPANY

Companhia de Saneamento Básico do Estado de São Paulo - Sabesp is a publicly held company controlled by the São Paulo State, founded in 1973, that provides environmental sanitation services.

The Company is headquartered in the City of São Paulo, a relevant portion of its operation is in the Metropolitan Region of São Paulo, the largest metropolitan region of Brazil, with around 21.5 million people. We are considered one of the largest sanitation companies in the world in terms of population served. At the end of 2023, we were present in 376 municipalities, distributed across all Brazilian regions. We were responsible for serving approximately 62% of São Paulo's population, with 28.1 million people having water supply and 24.9 million people having sewage collection services.

Seeking to expand its operated area within the scope of the New Sanitation Framework, the Company innovated by being granted the contract to supply water and provide sewage services in the municipality of Olímpia, commencing water and sewage services operations in December 2023 through its wholly-owned subsidiary Sabesp Olímpia S.A.

Sabesp is also a minority shareholder of three other companies that provide water supply and sewage collection and treatment services, in addition to six other companies, in the sectors of energy, paving, and other sanitation-related services. More information on the investees is available in Note 12 to the Financial Statements referring to the fiscal year ended on December 31, 2023.

CORPORATE STRATEGY FOCUSED ON SUSTAINABILITY

By the very nature of its activities, which contribute to environmental conservation and people's health and quality of life, the sanitation sector has a close connection with the ESG Agenda. Aware of this significant contribution, Sabesp is expanding and enhancing its corporate strategy by adopting sustainable actions in all areas to make this strategy more relevant and robust.

We strengthened the social and environmental pillars in strategy to support the ESG Agenda, and we have corporate governance as our guide to ensure that we are aligned, attentive to impacts, and consistent and transparent deliveries.

In 2023, the Corporate Strategy was revised, and new strategic objectives, indicators, goals, mission, and vision were defined, as well as the creation of a purpose aligned with our essence to contribute to improving people's quality of life. Our strategic drivers are:

PURPOSE – Transforming people's lives for a more inclusive and sustainable society;

VISION – Being a global reference in innovation and sustainability in sanitation; and

MISSION – Providing sanitation services with excellence.

 

Sabesp also established its strategic objectives in:

·

Internal Processes: Increase Sabesp's process efficiency and strengthen the supplier chain;

·

Customers and Market: Be competitive to maintain and expand the operational area and be a reference brand in service provision in Brazil;

·

People and Innovation: Be a modern, inclusive, and innovative company; and

·

Sustainability: Promote sanitation universalization to generate positive impacts on society and the environment and maximize the economic-financial result to ensure Sabesp's growth and perpetuity.

These drivers and strategic objectives support Sabesp's ambition, launched in 2023, to be the best sanitation company in the world. By renewing our strategy, we incorporate people and the environment at the heart of the business.

The goal is to ensure the transformation of lives for a more inclusive and sustainable society, provide services with excellence, and strive to be a global reference on the theme. The guiding principles that drive our strategy aim to contribute to universalization in the operated municipalities, the development of socio-environmental improvement goals and targets, with increasingly sustainable energy sources by promoting the circular economy and caring for the community served.

At the same time, the guiding principles seek to favor financial return, with growth in new businesses, service provision integration for the Company, professional and personal development of our employees, and transparently guided business management.

Water Supply and Water Security

To supply a population of around 28.1 million people, we use a distribution network of 93.2 thousand km, bringing treated water from 235 Water Treatment Stations (WTSs) to consumers in 376 municipalities of the São Paulo State.

In 2023, Sabesp produced 2,985.2 million m³ of water, with the services coverage rate reaching 98% and the service rate totaling 94% in the operated area.

Long-term planning, higher adaptation to uncertainties by increasing water infrastructure, strategic risk management, and rational and conscious use of water are some of the main actions implemented by Sabesp to ensure water supply to the population served.

The Metropolitan Region of São Paulo (MRSP) is, unquestionably, the most complex to operate. Susceptibility to climate variations, high population concentration, and geographic location impact the region’s low water availability, which is considered critical.

To address this problem, Sabesp makes use of the Metropolitan Water Program (PMA), whose structure plan is based on the supply x demand forecast of the Water Supply Master Plan, which considers historical data, future scenario expectations, and risk parameters. In 2023, the PMA contributed to the expansion of the Rio Grande WTS, which is ongoing, and significant works in the municipalities of Guarulhos and Mauá.

The Integrated Metropolitan System (SIM) is composed of a solid water infrastructure consisting of nine production systems, which, together with the Guarulhos’ supply system, serve the MRSP. The water sources in this area can store about 1.9 billion liters of water and produce approximately 82 m³ of water per second. In 2023, the average monthly production of water to serve the MRSP was 64.8 m³/s. The water storage index at the end of 2023 was 67%, compared to 53% in 2022.

Permanent management of water sources allows for designing daily operational scenarios and long-term strategic hydrological models. To anticipate potential risks related to the operation, Sabesp also has a strategic and operational risk management structure and contingency plans for unavoidable incidents.

In the interior of the State, supply suffers less pressure because of the lower population and the existence of different sources of supply, which include wells to collect water.

In municipalities facing a more critical situation, we are implementing treatment stations and dams that should ensure water security for the coming decades. Furthermore, we have already mapped alternative water sources in the interior, which can be used in case of drought. In the case of more critical situations, we adopt emergency systems and other measures to avoid interruptions in water supply to the population.

In the coastal region, the Company continues expanding the water structure to improve services to the local population and the large number of tourists that overload the system with high consumption peaks in summer periods. On the Northern Coast, we started the construction of reservoirs in São Sebastião and Ubatuba to increase water supply capacity and ensure water security.

In the Santos coastal area, where water availability is limited, we use an integrated system similar to that used in the MRSP, which, despite the lower scale, allows transferring water among regions of lower and higher demand during more critical periods. In 2023, we expanded the capacity of the Mambu WTS and resumed the execution of five reservoirs in Bertioga, Guarujá, Santos, Itanhaém, and Peruíbe.

Additionally, to reduce the amount of treated water that escapes from the distribution networks before reaching customers, the Corporate Program for Reducing Losses, started in 2009, proactively conducts research on invisible leaks, adopts preventive and corrective measures to combat water losses, and manages nighttime demand, which involves reducing water pressure in the distribution network during the night when there is lower demand. In 2023, aiming to meet the needs of the MRSP water supply system, there was an operational adjustment in the execution time of nighttime demand management, reducing the period by an average of two hours. The program also collaborates with regularization in low-income areas, improving performance and fighting any waste in the network.

Real losses, which correspond to pipeline leaks, totaled 19.5% in 2023. Commercial losses (water consumed but not accounted for), caused by frauds, failures in the commercial registry, and under-measurement of water meters, accounted for 10% in the year. The sum of these two indicators results in total losses, which came to 29.5% in 2023. Currently, our water loss rate is 260 liters/connection/day.

Water reused from sewage treatment also aims at increasing the sustainability of water resources, especially in a scenario of growing climate pressure. Water is reused in industrial activities and for urban needs, such as the cleaning of streets and street markets, and irrigation of parks. In 2023, the program reached the milestone of 100 million m³ of reuse water produced and supplied to the Capuava Petrochemical Complex and industries in the ABC Region of São Paulo.

Water quality control

Ensuring the delivery of quality water is the greatest asset we can offer our customers and one of the greatest assets of our business, and requires careful monitoring throughout the entire process, from collection and treatment to points of distribution and consumption.

The quality of water distributed is monitored by Sabesp and inspected by the Sanitary Surveillance units of the São Paulo State. The total number of analyses comprising the water quality monitoring network, dedicated to conducting tests for turbidity, color, chlorine, and total coliforms, accumulates about 68,000 monthly samples. In addition to these analyses, monitoring of more than 90 parameters is also carried out, under the responsibility of the 16 quality control laboratories, at various frequencies and points located along the various phases of the supply systems, in addition to operational control at the water treatment stations conducted by the laboratories located at the stations. Sabesp's laboratories are accredited to ISO 17.025 and certified by the National Institute of Metrology, Quality and Technology (Inmetro).

Expansion of Sewage Services

The sewage collection and transportation network operated by Sabesp has around 63.6 thousand km and carries sewage to be treated in its 596 Sewage Treatment Stations (STSs), which, in 2023, ensured that 93% of sewage was collected, 85% of people was served, and 85% of the households were connected to the sewage treatment service, resulting in approximately 24.9 million people served.

To continue progressing, the Company holds actions and has structuring programs to expand the sewage collection and treatment structure, as well as the connections of households to the collection and treatment system.

In the Metropolitan Region of São Paulo, the most complex in terms of expansion of the health sewage structure in the operated area, Sabesp has been counting on the Tietê Project since 1992 to expand the sewage collection and treatment infrastructure. The project has already provided collection and treatment services to more than 12 million people.

Since its start, the Company invested US$ 3.8 billion in the project, leading to significant increases in the coverage rate with collection networks, moving up from 70% to 93%, and in the treatment rate of collected sewage, which increased from 24% to 85% in the area covered by the project.

Further to the actions of the Tietê Project, the IntegraTietê Program was launched in March 2023 by the Secretariat of Environment, Infrastructure, and Logistics of the São Paulo State, and includes short-, medium-, and long-term measures for the cleaning and revitalization of the Tietê River. Sabesp will be responsible for taking care of the axis related to health and quality of life, which aims at expanding the sanitation network and waste management.

The proposal includes expanding the capacity and modernizing Sewage Treatment Stations with a focus on the circular economy, transforming them into resource recovery units through the processing of sludge and gas generated in the process, as well as installing photovoltaic plants.

In the coastal area of the São Paulo State, the Company maintains the Clean Wave Program, the largest environmental sanitation program on the Brazilian coast. The purpose of the program is to universalize swage services in the region, contributing to improving health, quality of life, and beach bathing quality, benefitting approximately 3.5 million people, including the local population and tourists that visit the region, mainly during summer. The program is in its second stage, and since its inception, in 2007, 118 thousand sewage connections have been implemented, raising the sewage collection rate from 53% to 86%, with 100% of collected sewage treated.

In 2023, we continued ongoing works, such as the sewage system in the Gaivotas neighborhood, in Caraguatatuba; the Barra do Una Sewage Treatment Station, and the Maresias Sanitary Sewerage System, in São Sebastião; the expansion of the Main Ubatuba Sewage System, with the expansion of the STS and the Tamoios Sewage Pumping Station; and the construction of a new treatment plant and effluent collection network in Ilhabela.

In the interior region, nearly all municipalities operated have universalized service rates, and the Company focuses on expanding the infrastructure to isolated communities, outside the urban centers.

New Organizational Structure

Upon reaching our 50th anniversary, we renewed and updated our governance structure, and strategically planned to be more consistent and dynamic. One of the main pillars of the transformation was the reorganization of the areas of operation within the various offices and the creation of new structures that would optimize the Company's growth within the new scenario in the sanitation sector.

The changes made aimed to bring greater agility to the decision-making process through a more horizontal and dynamic structure, enabling the generation of scalable, agile, and efficient solutions to facilitate the adoption of best practices throughout the Company sustainably and innovatively, with data-driven decisions and aiming to rationalize financial resources.

Within the CEO’s Office, the areas of digital transformation, sustainability, and corporate governance were created, bringing agility and efficiency to the decision-making process associated with an ESG Agenda in the Company. On the operational side, we feature the unification of two Offices (Metropolitan and Regional Systems) into the Operations and Maintenance Office, which, with the optimization and horizontalization of the structure, focuses mainly on operational performance and watershed management, seeking to deliver the best service with the lowest cost and timeframe.

Two new Offices were also created: the Customers Office, which brings the customer to the center of the strategy, focusing on billing management and customer experience; and the Regulation and New Business Office, which expands the relationship with regulatory agencies and the granting authority, acting both in the contractual management of the Company's current businesses and in new concession and public-private partnership contracts.

In the Economic-Financial and Investor Relations Office, the main changes are related to process integration and review and the incorporation of technological improvements, with emphasis on the establishment of the Integrated Services area, in the model of a Shared Services Center (SSC), which is in the process of implementation.

The Engineering and Innovation Office continues to focus on planning, prioritization, and execution of the Company's investments, being responsible, among other matters, for asset engineering and management, environmental management, and research, development, and innovation.

The People and Corporate Management Office encompassed activities related to corporate, personnel, asset, and procurement management, as well as legal and compliance areas.

Relationship com Customers

The creation of the Customer Office in 2023 reaffirms our commitment to putting customers at the heart of our strategy. The new office aims to foster constructive and inclusive commercial relationships with customers, focusing on excellence and innovation in customer experience, ensuring their satisfaction, which we expect to translate into increased revenue. To fulfill this assumption, the Customers Office is structured around two main pillars: Customer Experience and Billing Protection.

To ensure the integration of operational procedures involving customer relationships, 15 Customer Service Departments (SaCs) were created and distributed in the operated area, responsible for customer service, service provision, billing, collection, and customer satisfaction assessment.

In 2023, we intensified our digital transformation by expanding our services to digital relationship channels. With the migration to the virtual environment, the process gained greater agility, especially in the effectiveness of service, due to a smarter system and simpler and faster negotiations. An example of this initiative was the consolidation of our WhatsApp, Chat Bot, and the new cloud-based service platform, which provides more consistency to our customers and supports new Omnichannel communication channels and tools (simultaneous and interconnected use of different communication channels).

Throughout the year, we held two debt renegotiation fairs, resulting in more than 500 thousand agreements. Additionally, we maintained our strategy of using mobile service vans parked in various locations to facilitate our customers' access. This initiative allows for the negotiation of overdue bills, updating customer records, requesting water and/or sewage connections, requesting consumption reviews, or requesting repairs to networks.

Throughout the year, we added services and improved customer service through multi-channels. We also opened a new cloud-based Virtual Branch, which is much faster, more secure, intuitive, and personalized. This platform was designed based on customer feedback. In 2023, our customers’ satisfaction level was 84%, according to the annual satisfaction survey conducted by GMR Market Intelligence Institute.

Furthermore, we continue to provide an ombudsman service to customers, which exclusively handles complaints, suggestions, reports, criticisms, and requests for information about services. Over 2023, the Ombudsman Channel received more than 104.9 thousand complaints, 99.2% of which were solved.

Innovation and New Businesses

In 2023, we made progress in structuring innovation within the concept of Open Innovation, investing in the development and implementation of initiatives that integrate ideas, thoughts, processes, and research contributions from internal and external stakeholders of the Company.

Currently, an enhancement is underway in our structure with the establishment of innovation hubs (HUBs) progressively installed in the different operational and support business units of the Company. These hubs serve as channels for the entry of new technologies integrated with corporate innovation management.

We are also developing a digital open innovation platform to receive proposals from startups and universities in cooperation with the Inter-American Development Bank (IDB) in the public call for technological innovation projects. These actions aim to encourage creativity and broaden the participation opportunities of employees from different areas and other companies, aggregate greater effectiveness in idea generation and selection, and develop and disseminate innovative solutions.

In the sanitation area, we pioneered the advanced use of the Building Information Modeling (BIM) methodology, a tool that enables the creation of three-dimensional digital models of engineering works and integrates information from various disciplines and stages of the project lifecycle. Through BIM, it is possible to plan, design, build, and operate more efficiently, economically, and sustainably. In 2023, we developed tools to support contracting, modeling, and standardization of projects and storage, sharing, and management of models and documents within the BIM methodology.

On another innovation front, we have adopted artificial intelligence for the detection of non-visible leaks in the water distribution networks of Franca and municipalities in the region. The technology is based on the sounds generated by leaks to identify and locate points of water leakage that do not surface in the streets. The methodology provides an improvement in data collection, agility, and greater tracking accuracy, allowing for a rapid reduction in the volumes of water lost in distribution networks.

In 2023, we created the Sustainability and Innovation Committee as an advisory body to the Board of Directors to foster, discuss, review, and supervise sustainability and corporate governance initiatives and projects, as well as innovation. The Committee also proposes process improvements, goals, and performance aiming to contribute to the strengthening of our corporate strategy.

Through the partnership with FAPESP, we are involved in the development of basic and applied research projects under the Program for Supporting Research in Partnership for Technological Innovation. The 12 projects selected in the third call for proposals are currently in the development phase. In addition, through a second partnership with FAPESP, which is part of PIPE (Small Business Innovative Research Program), the first call aimed at accelerating startups was held in 2022. It is a pioneering opportunity in Brazil for companies with this profile that offer innovative sanitation projects. The proposals were evaluated and qualified in 2023, and one of them was chosen to develop its project with financial resources from Sabesp.

Aligned with business planning, the structuring of Research, Development, and Innovation actions is based on the concept of circular economy, within which the waste from a process is used as inputs for the production of new products and new cycles. Thus, we have been making efforts to leverage innovative projects aimed at the circular economy, in compliance with ESG principles, such as the use of biomethane for vehicular use and agricultural application of sludge, among others. As a result, we are studying the replication of the successful model being implemented in Franca, which integrates the liquid, solid, and gaseous phases of sewage treatment, in six other large-scale sewage treatment plants of the Company.

On the new business front, we won the concession of the municipality of Olímpia in May, to provide water supply and sewage services for 30 years starting in December 2023.

People Management

Further to the Company’s restructuring, under the new strategic guideline for efficiency and process simplification, we launched the Incentivized Dismissal Program (IDP). The adhesions to the program occurred in June 2023, and the Company follows a schedule for the termination of participants expected to occur between July 2023 and June 2024, ensuring that the process takes place gradually and planned, thus avoiding the risk of discontinuity in activities. Termination costs were recognized in the second quarter of 2023. The IDP had the adherence of 1,862 employees, accounting for about 15.2% of the Company's workforce in June 2023.

At the end of 2023, our staff totaled 11,170 employees divided into operational, technical, university, and managerial categories, taking into consideration the level of education, professional experience, the complexity of duties, and technical qualification. Our workforce is composed of 8,983 men (80.4%) and 2,187 women (19.6%).

We adopt a wage policy linked to the Jobs and Salaries Plan that attracts, retains, and trains qualified and committed professionals, offering career and compensation possibilities compatible with the market. Aiming to increase engagement and recognize our talents, in addition to the legal benefits, we also offer our employees meal vouchers, food vouchers, Christmas baskets, private pension plans, medical assistance, and educational assistance.

We have adopted the competency-based people management model, which continuously seeks to ensure innovation, flexibility, continuous improvement, high performance, and workforce engagement. Competency-based people management is a model that allows us to integrate our processes and includes continuing education, career management, quality of life, management of our organizational culture, and well-being and human resources services, among others. All employees annually undergo an Evaluation of Skills and Results that lead to the creation of the Individual Development Plan. In 2023, approximately 4,000 employees were promoted through this process.

The Company annually establishes a Profit Sharing Program (PPR) to encourage employees to achieve the organization’s goals. The PPR distributed in 2023 used the Company’s total and sectorial performance indicators for 2022, and 79.1%, on average, of the goals, were achieved.

To encourage the training and development of its employees, Sabesp has the Sabesp Business University (UES), which celebrated 20 years of history in 2023. The UES coordinates corporate processes of workforce training and development, enabling all necessary training for the exercise of professional duties and safety in the workplace. The portfolio of courses and programs offered by the UES includes paths such as the More Knowledge Program, which provides educational subsidies for professional certification exams, technical courses at the high school level, undergraduate, graduate, university extension, and language courses to increase the education level and qualifying employees. In 2023, 458 educational subsidies were granted.

Among the UES programs, we also have the Leaders Development Program, which aims to develop an innovative leadership culture that leads to actions aimed at establishing a new organizational culture, with a greater focus on results, innovation, and competitiveness. Furthermore, to develop and stimulate the culture of innovation and entrepreneurship through the generation and sharing of ideas from employees, we periodically carry out the Sabesp Entrepreneur Award, which had the participation of 429 professionals in its 6th edition.

We want our employees to have equal professional opportunities, and seek to address diversity in a fair and balanced manner. In 2023, we launched the "By Their Side" campaign, a mentoring program for women, aimed at creating a personalized, trustworthy, and assertive channel. This initiative provides female employees with the opportunity to talk to people with seniority and decision-making capabilities, who voluntarily make themselves available for any situation. The network's launch marked Sabesp's clear position regarding gender equity.

The Company is against prejudice related to origin, race, gender, color, sexual orientation, age, religious belief, or any other form of discrimination. In the case of non-compliance with our Code of Conduct and Integrity, we make available the Whistleblower Channel, which operates autonomously and confidentially. The channel is available for all employees and receives reports on harassment and discrimination.

The Harassment Verification Committee checks the content of the reports and, if discrimination is identified, the accused employee is subject to disciplinary measures. Even if the report is unfounded, the Committee tends to suggest to the area of origin the implementation of an Action Plan to guide, sensitize, and raise awareness among employees.

The Company has historically maintained a good relationship with representative entities, seeking to meet the main employee demands, always respecting the limits of its financial capacity and legal and governmental guidelines. In its labor relations, the company prioritizes negotiation as a means of resolving conflicts, substantially reducing the occurrence of strikes. Of the total employees, approximately 65% are union members.

In May 2023, we signed the 2023/2024 Collective Bargaining Agreement (ACT) with the unions, which is valid until April 2024. In the Agreement, we recognized 107 union agents/representatives, who enjoy job security during the ACT's validity. We also admitted the compensation of another 35 union leaders who are away for union activities and who operate in all our units, so that there are no operations without representation. The ACT resulted in an increase in salaries, meal vouchers, food assistance, and daycare grants by 4.52% (IPC/FIPE accumulated from May 2022 to April 2023), maintaining the clause that guarantees the employment of 98% of our employees and the exceptional Christmas food assistance. The turnover rate stood at 5.7% in 2023.

In 2023, we experienced two one-day strikes, which did not interrupt the essential services we provide. According to the legislation, our non-administrative employees are considered essential workers and therefore have their right to strike limited.

At Sabesp, caring for employees’ safety and health is an essential factor in increasing productivity and service quality, achieving better results, and promoting their well-being.

For this reason, we have an Occupational Health and Safety Management System (SST) that follows the rules established in the Regulatory Standards of the Ministry of Labor and Social Security, with elements based on ISO 45001 – Occupational Health and Safety Management System.

Among the instruments that contribute to ensuring the lives and health of employees are the identification and analysis of risks, participation and consultation with respective professionals, their training and awareness, operational controls, evaluations and preparation, emergency response, and Occupational Health and Safety (OHS) Diagnosis (Documentary Audit). The system covers all workers (both owned and outsourced) and activities carried out in the Company. Contracted companies must also follow our guidelines and requirements through contractual clauses. To this end, we monitor their services and work.

We ensure the quality of OHS processes using the Preliminary Risk Analysis methodology to detect hazards, assess risks, and adopt control measures in all our activities. The Risk Management Program (PGR) identifies risks according to the Homogeneous Exposure Groups, through the Risk Inventory, defining which control measures and corrective actions will be established in an Action Plan. Aligned with the PGR, the Occupational Health Medical Control Program provides the management of identified occupational risks.

Despite continuous efforts, 117 occupational accidents occurred in 2023, with a frequency rate of 5.46 accidents per million man-hours worked and a severity rate of 49 accidents per million man-hours worked. We did not record any fatalities in 2023, and we had 11 cases of employees absent due to occupational diseases. The absenteeism rate stood at 2.4% in 2023.

Organizational climate management is constant, and we seek to maintain an excellent climate and a great workplace for all employees through improvement plans at all levels and areas. In 2023, we re-applied the climate survey, which was conducted during a period of restructuring and changes in the organization. Using the methodology of the global consultancy GPTW - Great Place to Work®, the survey presented a favorability rate of 64% in its overall result.

ESG AT THE HEART OF BUSINESS

In 2023, we created a Sustainability and Corporate Governance Superintendence directly linked to the CEO’s Office. The mission of the new area is to centralize the ESG agenda, promoting greater integration with the business strategy and expanding the scope of the Company's ESG actions. The Superintendence is responsible for aligning all projects, practices, and initiatives we carry out and developing the guidelines for what should be done in the ESG journey. With this mapping, it is possible to analyze and choose the most effective practices that deliver greater value to society. Then, these best practices can be replicated throughout Sabesp, ensuring continuous evolution.

These are urgent and important topics that have been addressed by Sabesp in the last few years but are now implemented in a more integrated way, increasingly progressing in terms of sustainable practices and new market opportunities. The good management of ESG principles enables reducing risks, discussing sustainable guidelines and metrics, and strengthening the brand image before society, resulting in social-environmental responsibility, reputation, and higher credibility.

In 2023, we developed the 1st Framework for Sustainable Finance, a document describing key information about operations and strategies related to ESG issues, which allows the Company, upon its publication, to enable green, blue, social, or sustainable fundraising through the issue of financial instruments and/or securities in the capital market, banking market, and/or through development and multilateral agencies. The type of the Framework is "Use of Resources", which is characterized by the allocation of funds raised, or an equivalent amount, to projects that generate positive environmental and social impacts, or have both impacts.

In addition to these actions, it is worth noting that the Sustainable Development Goals (SDG), established in the UN’s Agenda 2030, are already internally addressed and align the Company with urgent global requirements. In 2023, we renewed our partnership with the United Nations Framework Convention on Climate Change (UNFCCC) for three years. The goal is to develop projects and exchange knowledge with UN-affiliated entities and place us as a model company in terms of SDG compliance, being the only Brazilian company to have such an agreement. In 2023, we participated in a special delegation at the 28th Conference of the Parties (COP28), a forum linked to the 28th United Nations Climate Change Conference, held in Dubai (United Arab Emirates), and the initial meeting for the 10th World Water Forum, as a member of the World Water Council.

Below are the Company’s main ESG practices and projects. These and other initiatives are available in detail in the Sustainability Report, on the Company’s website at https://ri.sabesp.com.br/a-companhia/relatorio-de-sustentabilidade.

Environment

Environmental issues are addressed in a cross-cutting manner, allowing the ESG agenda to permeate all levels, from strategic to operational. The high level of employee involvement results in greater agility in implementing actions, programs, and projects that will lead the Company's name toward its purpose of contributing to the construction of a more inclusive and sustainable world.

We are committed to improving the environment, people's lives, and the planet. According to our Institutional Environmental Policy and considering the current corporate strategy that places sustainability at the center of business, corporate environmental programs have gained new momentum, reflecting our commitment to proactively address environmental challenges and promote sustainable practices.

Based on the sustainability guidelines defined at the Company's strategic level, environmental programs are developed and implemented in an integrated manner, consolidating the culture of environmental protection and strengthening our commitment to environmental compliance and sustainability in providing sanitation services.

With the recent reorganization of our organizational structure, the environmental licensing process for works and projects has been centralized. This change allows for a comprehensive view of all stages of the process, from conception to decommissioning of facilities, and provides more efficiency and agility in the activities necessary for licensing.

For balancing public civil actions and environmental investigations that involve the Public Prosecution Office, Sabesp has sought the formalization of Consent Decrees (TACs) and Judicial Agreements (AJs), benefitting the planning and execution of works within feasible deadlines, integrating these obligations to the Company’s budget priorities.

To offset the environmental impact caused by the expansion of sanitation systems, the Company formalizes obligations with the environmental authority through Terms of Commitment for Environmental Recovery (TCRAs). Through the methodology adopted, native regional species are planted, followed by maintenance activities to accelerate the natural regeneration process of the Atlantic Forest and Cerrado biomes.

For the effective implementation of plantings, we have established a Corporate TCRAs Program with Cetesb (Companhia Ambiental do Estado de São Paulo) to expedite these processes. The Program enabled addressing existing TCRAs, as well as forming a bank of areas to meet future licensing obligations (the total area under restoration exceeds the total area of committed obligations), resulting in a surplus that can be used to meet future licensing obligations.

By 2023, approximately 840 thousand seedlings had been contracted, of which approximately 632 thousand (75.2%) have already been planted under the State Government's Springs Program and are in the maintenance phase.

Furthermore, aiming at monitoring and controlling impacts on biodiversity, the Company manages possible impacts resulting from the implementation of the infrastructure necessary to provide services even during the environmental licensing phase of the projects and is aligned with the requirements of environmental legislation at the federal, state, and municipal levels. Accordingly, it is possible to define, where applicable, plans and/or programs that have measures to prevent or mitigate impacts.

In 2009, we began the voluntary implementation of the Environmental Management System (EMS) in WTSs and STSs to identify the demands of the stations and implement the necessary solutions to maintain environmental and legal compliance. We have adopted two environmental management models: the first is the ISO 14001 standard model, adopted by the 36 stations that have this certification, as well as by stations that are seeking this certification. The second is our own model, the Sabesp EMS, which uses the principles of the standard as a reference, although it does not require certification for the unit. In 2023, Sabesp EMS reached 678 stations, accounting for 80% of our units in operation.

One of the objectives of Sabesp’s EMS in the Company is the adoption of good environmental practices in operations. Whenever necessary, resources are allocated for physical interventions aiming at the adequacy and improvement of the infrastructure of the facilities and their maintenance. The System facilitates the management of renewal deadlines and compliance with environmental license conditions, grants, and other obligations.

The environmental diagnoses and studies we carry out during the environmental licensing processes contribute to assessing the impact of interventions on biodiversity and guide our choices toward alternatives that are more beneficial to the environment. If necessary, we define plans and/or programs that have measures to prevent or mitigate such impacts. Among them, we can mention the Programs for Fauna Monitoring, Wild Fauna Conservation, Rescue and Salvage of Wild Fauna, Forest Management and Replacement, and Monitoring Water Quality and Aquatic Life.

To protect the edges of water sources, essential for water quality protection and system sustainability, the Company preserves and monitors about 49 thousand hectares of areas in the Atlantic Forest, distributed within and around the MRSP, where the main water sources used for public supply in the region are located. In this context, the Metropolitan Watersheds Green Belt Program was created. It integrates the São Paulo Government State's Springs Program, whose main result was the expansion of vegetation cover around the reservoirs of the Cantareira System, reaching approximately 80% in 2023.

The Sustainable STSs Corporate Program, implemented in 2019, aims to develop and disseminate the culture of sustainability by implementing actions that make it possible to transform the byproducts generated at the STSs such as biogas, sludge, and effluents, into sustainable resources, considering their energy use, providing greater emphasis on initiatives that aim at contributing to the reduction of greenhouse gas emissions.

The program has its own certification system and establishes sustainability levels based on the adoption of good practices and interventions for sustainability carried out at each station. Of the 44 units currently integrated into the Program, 11 have been recognized as sustainable. The other stations are in the process of studying and implementing infrastructure improvements to obtain their recognition.

To monitor the water use charging process, specific laws, and Basin Plans, we have the Institutional Representation Management Program in the Water Resources Systems. We are represented in plenary sessions and technical chambers in the 21 State Watershed Committees, 4 Federal Committees covering the São Paulo State, and the State Water Resources Council.

In addition to advertising campaigns for water conservation, the Company maintains the Water Rational Use Program (PURA), which adopts an incentive policy with technological actions and cultural changes, bringing solutions for leak detection and repair and replacing conventional equipment with water-saving equipment, in partnership with public institutions. Additionally, PURA promotes studies for water reuse and awareness through educational lectures and training.

In addition to expanding sanitation infrastructure, we maintain a Corporate Environmental Education Program (PEA Sabesp), the Sabesp 3Rs Program aimed at good practices in waste management generated in administrative areas, Used Cooking Oil Recycling Programs, which encourage proper disposal of the product, Sabespfértil, an organic fertilizer produced through treated sewage sludge, as well as other initiatives for sludge processing. We also have community engagement programs, through which our agents promote workshops, courses, visits, and events to encourage collective engagement in the creation of a healthier urban environment.

We have a risk matrix that considers, among the risks and impacts on the provision of our services, those resulting from climate change and extreme events, such as torrential rains and prolonged droughts. Such events can reduce water availability, compromise facility operation conditions, lead to input supply restrictions, and change consumption patterns, among others. Accordingly, we make investments in infrastructure to increase water availability and the resilience, adaptation, and flexibility of our systems.

In 2023, for the first year, we celebrated the achievement of the Gold Seal of the Brazilian GHG Protocol Program, awarded to companies that present complete greenhouse gas (GHG) emission inventories verified by an independent organism accredited by Inmetro. It is the highest level of qualification and contribution to mitigate GHG emissions, reflecting Sabesp's commitment to the technical improvement of our inventories and delivery of consistent results.

The GHG emissions inventories which include scopes 1, 2, and 3, follow the methodology of the Intergovernmental Panel on Climate Change (IPCC) and have been prepared since 2007. Data from Sabesp’s last available GHG emission inventory, referring to 2022, which accounts for emissions from our processes, confirms that sewage collection and treatment activities (included in Scope 1) continue to be the largest sources of emissions, accounting for 91.8% of the total. Electricity consumption accounted for 5.7% of the total while other activities accounted for approximately 2.5%.

It is worth noting that the expansion of sewage collection and treatment systems brings a progressive increase in GHG emissions and, therefore, a greater generation of biogas and waste at STSs. On the other hand, the expansion of basic sanitation directly contributes to the reduction of GHG emissions from water bodies.

As for reducing emissions, additional efforts toward the universalization of sewage treatment are required through adjustments and operating improvements aimed at the sustainability of processes, including the optimization of operations and the implementation of less carbon-intensive initiatives.

Among the actions to mitigate GHG emissions, we can highlight projects with positive impacts in the reduction of GHG emissions, which have been implemented and are under development, aiming at biogas energy use, hydroelectric potentials, and generation of inputs for agricultural activities, sustainability of the vehicle fleet, and forest restoration and maintenance.

Regarding electricity consumption, a key input in the provisions of basic sanitation services, in 2023, we used 2,657 GWh, down by 3.4% from the 2,752 GWh used in 2022. In 2023, we acquired approximately 64.7% of our total energy consumption in the Free Market Tariff (ACL) and 35.3% in the Regulated Market Tariff (ACR).

Through SPE Paulista Geradora de Energia, we are coupling small hydroelectric power plants to the Cantareira System installed at the arrival of raw water and installing floating photovoltaic panel plants to harness energy generation potentials in watershed areas, on the water surface of dams and reservoirs.

In 2023, Incentivized Energy Source in ACL accounted for 14% of the total consumed by our activities. The Program for Distributed Generation of Photovoltaic Energy started the operation of 11 other plants, totaling 16 plants in operation and 19.5 MW of generation (34% of the total), with the program expected to be implemented in 2025.

Social

In its pursuit to contribute to the professional and personal development of its employees, the Company works on the training and engagement of its workforce, identifying talents, providing continuous access to operational, technological, and managerial knowledge, and creating safe, healthy, and innovation-friendly environments to enhance values, especially with the new reality imposed by the New Legal Framework for Sanitation, with increased competitiveness in the sanitation market. For further information on Sabesp’s people management, see item “People Management” of this Report.

In addition to taking care of the people who make up the Company's workforce, Sabesp focuses its efforts on serving the general population with excellence in service delivery, with significant positive impacts on society, contributing to delivering more quality of life and dignity to the entire population. In underprivileged communities, we operate with lower tariffs and social programs that allow for income, education, and healthcare.

The Company continued progressing in 2023 to provide increased basic sanitation to social groups and communities served, mainly the most vulnerable ones. We maintained programs, actions, and projects to strengthen dialogue and relationship with this public, with initiatives aligned with the regional and socio-economic features of the areas and communities to be benefitted.

The Company uses its Água Legal Program to tackle the problem of accessing water in irregularly settled communities, which are precariously supplied by improvised pipes that are subject to contamination. Households served are automatically included in the social water tariff for two years, which can be renewed. By 2023, the program had already regularized 142,942 water connections and 13,809 sewage connections only in the MRSP, benefiting over half a million people.

The social and vulnerable tariff is a benefit granted to low-income families or those in vulnerable situations, covering all municipalities operated by Sabesp. At the end of 2023, the benefit was granted to 964,720 low-income families, of which 560,379 from the Social category (R$ 11.19 for consumption of up to 10 thousand liters of water per month) and 403,981 from the Vulnerable category (R$ 8.53 for consumption of up to 10 thousand liters of water per month). In 2023, 119,884 families were benefitted in both categories.

With the Clean Stream Program, an initiative in partnership with the São Paulo Municipal Government, Sabesp has already cleaned and monitored 161 streams in the São Paulo capital, benefitting more than 3 million people. Currently, our task is to map, inspect, and maintain collection networks, execute relocation works, connections, interconnections, and extension of collection networks, and monitor the water quality of streams. We also conduct awareness and environmental education of the local population about indiscriminate dumping of garbage in watercourses or even on the streets.

Furthermore, aiming at generating positive social value by promoting solidarity with vulnerable groups or communities through company actions or actions in partnership with civil society organizations, Sabesp develops the Corporate Volunteer Program. Among the actions developed in 2023, the highlight was the SOS North Coast where we assisted families affected by rains, contributing with donations of food, clothing, hygiene, and cleaning products. More than 105 tons of food, over 123 thousand pieces of clothing, and more than 75 thousand hygiene and cleaning items were collected.

To assist more vulnerable communities in generating new sources of income, the Company has the Teaching to Fish Program, through which a free course on residential hydraulic installations is made available to low-income and/or unemployed people. The classes cover topics such as the environment, tariff calculation (water bill), family sewage system, cold water installation, leakage research, metal and sanitary ware installations, entrepreneurship, and employability.

Sabesp also promotes actions toward the efficient and responsible use of water, spreading the awareness on the finitude of water resources. The recent climate uncertainties reinforce the importance of these initiatives, which have been contributing to the average per capita reduction in water consumption in the last few years.

 

Governance

Sabesp is a publicly-held company controlled by the São Paulo State, which holds most of the Company’s shares. The remaining shares are traded on the São Paulo stock exchange, in the Novo Mercado segment of B3 S.A. – Brasil, Bolsa, Balcão , and on the New York stock exchange, as Level III American Depositary Receipts. The Company was the first in the Brazilian sanitation sector to become part of both segments in 2002. Strong and consolidated governance is one of the Company’s strengths.

For being controlled by the State and operating in a regulated environment, the Company is also subject to the controls of environmental and sectorial regulatory authorities, as well as to the Accounting Court of the São Paulo State. In addition, we participated in the National Corruption Prevention Program (PNPC), coordinated by the Control Network in the States and sponsored by the Office of the Federal Controller General (CGU) and the Federal Accounting Court (TCU).

The Company’s strategic guidelines are defined by the Board of Directors, which is currently composed of 10 members, one of whom is the CEO and another one represents the employees. Four of the 10 Board members are independent and one of them is the representative of the minority shareholders. The Board of Directors is assisted by a Statutory Audit Committee, whose members are all independent.

The Executive Board, which was renewed in early 2023, is responsible for the Company’s executive management and is currently composed of seven members, of whom three are women and four are men. For further information on the profile of the Executive Board’s members, visit https://ri.sabesp.com.br/governanca-corporativa/conselhos-comites-do-conselho-e-diretoria.

Through an independent consulting firm, the Company annually evaluates the Board of Directors, statutory committees, and the Executive Board and their committees, in a collegiate and individual manner, including matters related to the members’ performance and conduct. The result of the evaluation is used to instruct the implementation of improvements in the organization and identify matters to be improved by the Board of Directors and Executive Board.

The Company also has a permanent Fiscal Council, installed since its creation, currently composed of four sitting members and four alternate members. Minority shareholders have the right to appoint representatives (both sitting and alternate), but currently, there are no nominations from them.

The Eligibility and Advisory Committee, composed of three members, all appointed by the majority shareholder, is responsible for overseeing the processes of appointment and evaluation of executive officers and fiscal council members, under the Bylaws and the State-Owned Companies Law.

Through an independent consulting firm, we annually evaluate the Board of Directors, statutory committees, and the Executive Board. The evaluation addresses the adoption of good corporate governance practices and sustainability principles, the effectiveness of management performance, the contribution to results, and, among others, the implementation of goals and guidelines outlined in the strategic plans. The evaluation results are submitted to the State Capital Defense Council (Codec) and are used to guide the implementation of improvements in the organization and functioning of its units, as well as to identify topics that should be developed and explored.

Every newly arrived member of the Board of Directors and Executive Board must participate in an integration program. This program presents our business processes and key institutional documents. The program includes training on the Code of Conduct and Integrity, corporate and capital market legislation, risk management policy, information disclosure, and internal controls. The training is offered every year and to the members of the Fiscal Council.

The annual overall compensation to be paid to Management and members of the statutory committees and Fiscal Council is approved by the General Shareholders’ Meeting. The total compensation paid in 2023, in gross amounts, considering benefits, totaled R$ 9.5 million, including around R$ 1.9 million referring to the Executive Officers' variable compensation.

Integrity

We strive for the Company to be a reference in ethics and integrity for society. That's why we have structured an effective Integrity Program, whose goal is to engage everyone in following ethical values and principles in all tasks and relationships. Accordingly, we encourage transparent communication and decision-making that continuously seek to prevent behaviors related to corruption, fraud, and bribery.

The program also aims to improve employee satisfaction and retention by providing a favorable organizational climate, increasing internal trust, strengthening our reputation, and obtaining benefits such as reducing legal and regulatory risks, including harmful acts to the government.

The program is based on Brazilian and international laws, such as Law 12,846/2013, Law 13,303/2016, and the Foreign Corrupt Practices Act (FCPA), and includes internal mechanisms for monitoring and encouraging the reporting of irregularities, establishing guidelines and principles that guide all our stakeholders.

To disseminate and foster a culture of integrity, we also conduct training sessions that include members of the Executive Board, Board of Directors, and Statutory Committees, addressing ESG themes, with an emphasis on governance in state-owned companies, the role of the Board in decision-making, ethics and integrity, and the Sustainability Committee.

The pillar of this ethical and integrity commitment is the Code of Conduct and Integrity, the main corporate instrument to disseminate both the ethical conduct expected and the behaviors not tolerated by the Company, guiding its Board members, executive officers, employees, apprentices, interns, service providers, and partners, joining Sabesp, to develop the culture of integrity.

The Ethics Committee, linked to the Board of Directors and endowed with independence and autonomy, has the mission to disseminate, apply, and continuously update the Code of Conduct and Integrity, adapting it to reflect current scenarios and stimulate the commitment of administrators and employees to the principles established therein.

To ensure compliance with the Code of Conduct and Integrity, the Company provides the Trust Channel, aimed at solving doubts and guiding employees, and the Whistleblower Channel, managed by a specialized third-party company, with the guarantee of information confidentiality and whistleblower anonymity, aiming to detect and monitor misconduct, which are investigated and subject to disciplinary measures. The Ethics Committee is responsible for evaluating the results of the investigations received and the inquiries made through the channels, as well as the recommendations for preventive and corrective measures to be adopted.

In 2023, 572 reports were recorded in the Whistleblower Channel and 80 penalties were applied, among company employees and outsourced employees, of which 21 warnings, 11 suspensions, and 48 dismissals. It is worth noting that, among the penalties applied and cases investigated, there are no indications of the participation of Company employees in acts of corruption.

In 2023, Sabesp conducted 840 transaction analyses, focusing on conflicts of interest involving related parties. Starting in November, all transactions must be consulted before being formalized, and 116 reputational analyses (Integrity Background Checks) were performed.

Risk Management

To manage its risks, the Company has a Compliance and Risk area, created to, among other related functions, identify and manage corporate and operational risks, aiming to enhance corporate governance and the execution of strategic planning.

The Company also has the Corporate Risk Management Committee, which is advisory and permanent in nature, reporting to the Executive Board, responsible for monitoring the annual corporate risk management work plan approved by the People and Corporate Management Office. The Committee evaluates the Corporate Risk Management Policy and the levels of authority for approval and risk treatment; monitors the activities of risk identification, analysis, assessment, treatment, communication, and monitoring; tracks the progress of the implementation of mitigating action plans and risk indicators, and evaluates the corporate risk map; and advises the Executive Board on matters related to corporate risk management.

The Corporate Risk Management Policy aims to guide the Company in the practice of assessing risks in the corporate environment and contributes to the enhancement of governance, business planning, and value preservation and generation. To ensure systematic and standardized risk management, the Policy establishes guidelines, concepts, and competencies for conducting the risk management process, according to internally defined methodology, based on ISO 31000 standards and, above all, on the international COSO ERM model: Committee of Sponsoring Organizations of the Treadway Commission - Enterprise Risk Management 2017.

Internal Controls

The evaluation of internal controls is carried out by the internal audit, which is functionally subordinated to the Board of Directors through the Audit Committee and, administratively, to the Company's CEO’s Office. The area is responsible for assessing the adequacy of internal controls, the effectiveness of risk management, and governance processes, conducting audit projects based on the Annual Plan approved by the competent authorities, and investigating occurrences and coordinating investigative inquiries.

In 2022, the assessment of effectiveness, which comprised 225 internal controls, did not identify any material deficiencies. The tests for 2023, in line with the independent audit schedule, will be disclosed in the second quarter of 2024.

The audit of our financial statements and review of quarterly information and financing projects are performed by external auditors, ensuring the reliability of the data presented, which was once again recognized by the National Association of Finance, Administration, and Accounting Executives (Anefac), which awarded Sabesp with the 2023 Transparency Trophy, in the category Publicly-Held Companies with net revenue of more than R$ 20 billion.

We currently rely on the external audit BDO RCS Auditores Independentes, which started reviewing the quarterly information for September 30, 2023.

¹ Adjusted EBITDA corresponds to net income before: (i) depreciation and amortization expenses; (ii) income tax and social contribution (federal income taxes); (iii) financial income and (iv) other net operating expenses. Adjusted EBITDA is not a measure of financial performance according to the accounting practices adopted in Brazil, or IFRS - International Financial Reporting Standard; thus, it should not be considered in isolation, or as an alternative to net income, as a measure of operating performance, an alternative to operating cash flows, or a liquidity index. Adjusted EBITDA does not have a standardized definition, and the Company's definition of Adjusted EBITDA may not be comparable with those used by other companies. The Company's management believes that Adjusted EBITDA provides a useful measure of its performance, which is widely used by investors and analysts to assess performance and compare companies. The calculation of adjusted EBITDA by other companies may differ from the Company. Adjusted EBITDA is not part of the financial statements.

Adjusted EBITDA is intended to present an indicator of operational economic performance. Sabesp’s Adjusted EBITDA corresponds to net profit before net financial expenses, of income tax and social contribution (federal taxes on income), depreciation and amortization and other net operating expenses. Adjusted EBITDA is not a financial performance indicator recognized by the Corporation Law Method and shall not be considered individually or as an alternative to net income as a measure of operating performance, as an alternative to operating cash flows, or as a liquidity indicator. Sabesp's Adjusted EBITDA serves as a general indicator of economic performance and is not affected by debt restructuring, interest rate fluctuations, changes in tax burden or depreciation and amortization levels. As a result, Adjusted EBITDA serves as a suitable instrument to compare operating performance on a regular basis. In addition, there is another formula to calculate the Adjusted EBITDA that is adopted in some financial commitment clauses. The Adjusted EBITDA provides a better understanding not only of operating performance but also the ability to meet the Company's obligations and to raise funds for investments in capital assets and working capital. Adjusted EBITDA, however, has limitations that prevent it from being used as a profitability indicator because it does not take other costs resulting from Sabesp's activities or some other costs into account that may considerably affect its profits, such as financial expenses, taxes, depreciation, capital expenditures, and other related charges.

 

² Other net operating income/expenses refer mainly to the write-off of property, plant, and equipment, provision for loss with intangible assets, loss with economically unfeasible projects, deducted from sales revenue of property, plant, and equipment, sale of notices, indemnifications and refund of expenses, fines and collaterals, property leases, reuse water, Pura and Aqualog projects and services.

Fundraising and Indebtedness

Sabesp has a consolidated reputation in the capital market and solid relationships with public banks and multilateral Brazilian and international agencies. This mix and diversity of sources provide us with an extended debt amortization profile, at costs compatible with our investment cycle, especially credit lines granted by official Brazilian banks and multilateral credit organizations, as well as through the increasing issue of incentive debentures in the capital market.

In 2023, the Company prioritized the contracting of debt in local currency, totaling R$ 1.47 billion. Moreover, R$ 926.0 million related to reimbursements for financing investments already contracted in previous years were recorded.

On May 19, 2023, the Company raised R$ 470.0 million with the Inter-American Investment Corporation (IDB INVEST). The proceeds from this contract will be used to partially finance the Company’s investments related to the 4th Stage of the Tietê River Cleaning Project. The principal will be amortized in semi-annual payments in December and June, starting in December 2023 and ending in December 2036. Interests mature semi-annually in June and December, starting in June 2023 and ending in December 2036, at CDI + 0.5% p.a. The loan is collateralized by Société de Promotion et de Participation pour la Coopération Economique (PROPARCO). Interests mature semi-annually in June and December, starting in June 2023 and ending in December 2036, at CDI + 2.0% p.a.

On June 14, 2023, Sabesp contracted financing of R$ 1.0 billion with the International Finance Corporation (IFC). The proceeds were raised in September and November 2023 and will be exclusively used to cover the costs of the New Pinheiros River Program. The principal will be amortized in semi-annual payments in October and April, starting in October 2025 and ending in April 2033. Interests mature semi-annually in October and April, starting in October 2023 and ending in April 2033, at CDI + 1.7% p.a.

On March 05, 2024, we held the 31st Issue Debentures, in three series, totaling R$ 2.94 billion. The first, second, and third series will mature in February 2029, 2031, and 2034, respectively. The first, totaling R$ 507.0 million, yields CDI + 0.49% p.a., with semi-annual interest payments. The second, totaling R$ 1.73 billion, yields CDI + 1.10% p.a., with semi-annual interest payments. The third, totaling R$ 699.0 million, yields CDI + 1.31% p.a., with semi-annual interest payments. The proceeds from the issue will be used to refinance financial commitments falling due in 2024 and to recompose and reinforce the cash position. The Debentures are characterized as “ESG bonds for the use of sustainable and blue resources”, based on the Company’s commitment to allocate the equivalent amount in projects described in the Sustainable Finance Framework, which was duly verified and validated through a second opinion report issued by Attest ESG from Exame Ltda.

In 2023, the risk rating agencies have not changed the Company’s ratings, on the national scale, which remain as ‘AAA’. In July, Fitch upgraded the Company’s global scale rating in foreign currency from BB to BB+. In December, S&P upgraded the Company’s global scale rating from BB- to BB.

In the fiscal year ended December 31, 2023, the Company met all the requirements (covenants) of its borrowings and financing agreements. The table below shows the most restrictive clauses in 2023:

	Covenants
Adjusted EBITDA / Adjusted Financial Expenses	Equal to or higher than 2.80
EBITDA / Financial Expenses Paid	Equal to or higher than 2.35
Adjusted Net Debt / Adjusted EBITDA	Equal to or lower than 3.80
Net Debt / Adjusted EBITDA	Equal to or lower than 3.50
Other Onerous Debt(1) / Adjusted EBITDA	Equal to or lower than 1.30
Adjusted Current Liquidity	Higher than 1.00

(1) The contractual definition of “Other Onerous Debts” corresponds to the sum of pension obligations and healthcare plan, installment payment of tax debts, and installment payment of debts with the electricity supplier.

Total debt increased by 3.0% in 2023, from R$ 19.0 billion in 2022 to R$ 19.5 billion in 2023. Total indebtedness denominated in foreign currency fell by 1.1%, from R$ 2.8 billion in 2022 to R$ 2.7 billion in 2023, accounting for 14.1% of the Company's total debt at the end of the period (14.6% in 2022).

Amortization in local and foreign currencies totaled R$ 1.8 billion in 2023.

At the end of 2023, we had R$ 16.9 billion in long-term debt, R$ 2.5 billion of which was in foreign currency. Short-term debt totaled R$ 2.6 billion, of which R$ 250.0 million was in foreign currency.

Stock Market

The Brazilian market closed 2023 on an upward trend, with expectations of interest rate reduction. The Ibovespa index reached its historical peak of 134,000 points. Compared to the previous year, the stock market showed a 22.3% appreciation, contrary to the inflation trend, which decreased during the period, with the IPCA index closing at 4.6%.

In addition to the Ibovespa, the Company is included in the main Brazilian broad indexes, such as the IBRA (Brazil Broad Index), IBrX 100 (Brazil 100 Index), and indexes of companies with a high degree of corporate governance such as IGCT (Corporate Governance Trade Index), IGCX (Differentiated Corporate Governance Stock Index), and ITAG (Differentiated Tag Along Stock Index). In 2023, Sabesp's shares followed the market trend, maintaining the upward curve from the previous year and ending the period with an accumulated variation of 32%, priced at R$ 75.34 and a market cap of R$ 51.5 billion.

Amid a more favorable context in the Brazilian capital market, with the reduction in inflation linked to the decrease in domestic interest rates and high interest rates in the US market, Sabesp's shares were boosted by measures implemented throughout 2023, such as corporate restructuring, cost reduction, increased efficiency, and mitigation of regulatory risks. The market value generated in the period was R$ 12.4 billion, driven by the positive perception of shareholders and investors in general, reflected in the fundamentals and valuation by major market analysts.

The annual financial turnover of shares on B3 contracted from R$ 46 billion in the previous year to R$ 41 billion in 2023, which may indicate a trend towards longer-term strategies in the Company. The top 10 institutional shareholders of the Company increased their positions and accounted for 15% of the Company’s total shareholder base, excluding shares held by the controlling shareholder and ADRs, which accounted for 61.7%, maintaining a stable profile of the shareholder structure.

The American Depositary Receipts (ADRs) appreciated by 47% under the same fundamentals of the local market and the 8% depreciation of the U.S. dollar, which may be related to the decrease in the number of shares traded at NYSE, reducing the Company’s share capital from 12.1% in 2022 to 11.4% in 2023. The S&P 500 market index depreciated by 20% in 2023.

Dividends

According to the Company's Bylaws, the common shares are entitled to minimum mandatory dividends, corresponding to 25% of the net profit for the year, obtained after the deductions determined or allowed by law, and can be paid as interest on own capital.

The dividend distribution policy foresees that the payment of minimum mandatory dividends will be maintained until the universalization of the basic sanitation services is reached in the operated area and, when paid as interest on own capital, the income tax rate charged on the amount payable to shareholders will be considered an additional minimum dividend.

In 2023, Sabesp paid dividends as interest on capital totaling approximately R$ 872.2 million for 2022, corresponding to approximately R$ 1.2760 per common share, a payout of 27.9%, and a dividend yield of 2.2%.

For 2023, the Board of Directors approved the proposal to pay interest on own capital, totaling R$ 984.5 million, corresponding to R$ 1.4404 per common share, a payout of 27.9%, and a dividend yield of 1.9%, with payment scheduled for June 24, 2024.

• Municipality of Estância Turística de Olímpia

 

In July 2023, the Municipal Government of Olímpia – SP (“Olímpia”) approved the bidding process referring to Tender 02/2023, whose subject was the granting of a concession for providing public water supply and sewage services for 30 years, and awarded the contract to SABESP, with a fixed concession fee of R$ 148 million.

 

The municipality of Olímpia is located 430 km from the capital city of São Paulo, has an estimated population of 56 thousand inhabitants, and universalized water and sewage coverage. The municipality will require operational, commercial, efficiency, and water loss reduction efforts from the Company.

As established by the Bid Notice (Bid Notice), the winning bidder should create, before the signing of the agreement, a special purpose entity (SPE) to execute the terms of the Concession Agreement. The contract value estimated in the Bid Notice is R$ 1,182,495 (base date of August 2022), corresponding to the Granting Authority’s estimate of the cumulative concession revenues, while estimated investments amount to R$ 81,112 (base date of August 2022) for the entire duration of the concession.

 

The Notice also defines that the subscribed share capital of the Concessionaire, at the time of its creation, must be, at least, R$ 8,111. Therefore, on August 11, 2023, SABESP Olímpia S/A was created with the corporate objective of providing public water supply and sewage services in the Municipality of Olímpia. The subscribed share capital of the SPE was partially paid up by SABESP, totaling R$ 811 or 811,121 common shares, totaling 10% of the share capital. The remaining 7,300,087 subscribed common shares, totaling R$ 7,300, will be paid up within 60 months from the Commencement Order, which is issued by the Granting Authority that authorizes the start of the Concessionaire’s provision of services, under the provisions of the Notice and Agreement.

 

The Concession Agreement for the provision of public water supply and sewage services in the Municipality of Olímpia was executed on October 11, 2023.

 

Of the total, the amount corresponding to the fixed concession totaling R$ 148 million, 50% has already been paid by SABESP on August 30, 2023, i.e. R$ 74 million as a condition for the contract signing, and 50%, duly authorized by IPCA, will be paid by SABESP Olímpia S/A by 365 days after the payment of the first installment.

 

A monthly variable concession fee will be paid by the 10th day of the subsequent month, corresponding to 1% of the net tariff revenue.

 

To ensure faithful compliance with the obligations to be assumed by the Concessionaire, upon the signing of the agreement, proof of guarantee of the contractual obligations must be presented to the granting authority, in an amount corresponding to 5% of the estimated investment value.

 

Given that SABESP owns 100% of the SPE and meets control requirements, the Company consolidated SABESP Olímpia S/A, following the Accounting Policy described in Note 3.1.

 

The operations started in December 2023.

 

·        Privatization and Proposal of New Concession Agreements

On September 18, 2023, the Board of the State Privatization Program (CDPED) resolved to recommend that:

 

(i)   the Investment Partnerships Secretariat and the Environment, Infrastructure, and Logistics Secretariat take the necessary steps to submit the draft of the Company’s privatization law to the Governor’s office; and

 

(ii)   SABESP, under article 5, II combined with article 7, paragraph 2, and paragraph 4 of Law 9,361/96, starts the procedure for the selection and hiring of coordinating banks and other services required for the future public offering.

As of September 30, 2023, as provided for in paragraph 2 of article 14 of Federal Law 14,026/2020 (“New Legal Sanitation Framework”), the São Paulo State sent Official Letters to the municipalities operated by the Company with proposals to change the conditions of the concession agreements in effect (“Communication”).

The Communication highlights general aspects of the proposal for a new concession agreement (“New Agreement”) aiming at replacing the existing agreements, under article 14 of the New Legal Sanitation Framework, indicating that the following guidelines will be observed under the New Agreement to be executed with these municipalities:

(a) the anticipation of achieving the universalization goals established in the New Sanitation Framework for 2029, subject to any shorter deadlines contractually outlined;

(b) the extension of the concession agreement for 2060;

(c) the obligation of SABESP to serve the population residing in consolidated informal urban settlements and rural areas, covering the entire municipal territory; and

(d) the detailing of investments to be made in each municipality.

 

As of December 11, 2023, State Law 17,853 was enacted. It authorized the Executive Branch of the São Paulo State to promote privatization measures of Companhia de Saneamento Básico do Estado de São Paulo – SABESP. Among other aspects, as provided for in article 2, the model adopted for the privatization of SABESP must observe the following guidelines:

 

(i) compliance with the universalization goals of water supply and sewage services in all municipalities of the State served by the Company, considering the inclusion of rural areas and consolidated informal urban centers, under Federal Law 14,026, of July 15, 2020;

 

(ii) anticipation, to December 31, 2029, of the achievement of the universalization goals, subject to any shorter deadlines contractually agreed upon;

 

(iii) tariff reduction, preferably considering the most vulnerable population;

 

(iv) provision for the creation of an annual control to monitor compliance with the goals, with indications of investment requirements for the next few years;

 

(v) provision of quality services, aiming at improving the quality of treated water and reducing its loss;

 

(vi) guarantee, in the contractual instruments resulting from the privatization, to the employees listed in SABESP’s permanent staff at the time of the publication of this law, of stability, with the maintenance of their employment contract for 18 (eighteen) months from the date of effective completion of the Company’s privatization process.

 

As of December 21, 2023, the Company concluded the selection of financial institutions that will be the global coordinators of the financial institutions union responsible for structuring the Company’s potential follow-on. The selected Global Coordinators are i) BTG Pactual; ii) Bank of America; iii) CITI; and iv) UBS - BB.

 

As of February 15, 2024, as reported by the Company in a Material Fact, the São Paulo State opened a public consultation regarding the following documents:

 

(a) the draft of the Concession Agreement to be executed between the Regional Unit of Drinking Water Supply and Sewage Services 1 ("URAE-1") Southeast and SABESP, with the indication of the involvement of the São Paulo State Utility Services Regulatory Agency, along with the specific technical exhibits of the Municipalities comprising URAE-1, in addition to other contractual exhibits;

 

(b) the draft of the charter of URAE-1’s Decision-Making Board; and

 

(c) the draft of the Regional Sanitation Plan, under article 17 of Federal Law 11,445, of 2007.

 

The aforementioned Public Consultation on the privatization of Sabesp was concluded on March 15, 2024, with a significant number of suggestions submitted by the public. A total of 976 contributions were received through the Internet, in addition to 135 oral statements made at the eight public hearings held by the São Paulo State on the matter.

 

The next steps of the privatization consist of the São Paulo State's publication of the Public Consultation Contributions Report, concluded on March 15, 2024, with the revised documents sent to URAE 1 - Southeast for resolution.

 

 

Management expects that the funds raised with the improved water security from the works carried out, the generation of operational cash, and credit lines available for investments, will be sufficient to meet the Company’s commitments and not compromise the necessary investments.

 

Approvals

 

The financial statements were approved by the Board of Directors on March 21, 2024.

 

2

Basis of preparation and presentation of the financial statements

 

The Company’s financial statements have been prepared according to the International Financial Reporting Standards – IFRS, issued by the International Accounting Standards Board – IASB and according to the accounting practices adopted in Brazil, which observe the pronouncements issued by the Brazilian Accounting Pronouncements Committee – CPC. All material information related to the financial statements, and this information alone, is being disclosed and corresponds to the information used by the Company’s Management in its administration.

 

The financial statements have been prepared under the historical cost except for certain financial instruments measured at fair value when required by the standards.

 

The preparation of financial statements in conformity with IFRSs and CPCs requires the use of certain critical accounting estimates. It also requires Management to exercise its judgment in the process of applying the Company's accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the financial statements are described in Note 6.

 

 

3

Summary of material information on accounting policies

 

The material information of the accounting policies applied in the preparation of these financial statements are defined below and have been applied consistently in all years presented.

 

3.1

Consolidation

 

The Company controls an entity when (i) it has power over the investee; (ii) it is exposed to, or has rights to, variable returns from its involvement with the investee; and (iii) it has the ability to use its power to affect its returns.

 

When the Company does not hold the majority of voting rights in an investee, it will have power over the investee when the voting rights are sufficient to give it the practical ability to unilaterally conduct the relevant activities of the investee. When assessing whether SABESP's voting rights in an investee are sufficient to give it power, the Company considers all relevant facts and circumstances, including (i) the Company's proportionate interest in voting rights regarding the interests of other voting right holders; (ii) potential voting rights held by the Company, other voting right holders, or other parties; (iii) rights arising from other contractual agreements; and (iv) any additional facts and circumstances that indicate whether the Company has the ability to conduct the relevant activities of the investee.

The financial statements of the subsidiary are included in the consolidated financial statements from the date the Company obtains control until the date when such control ceases to exist. Revenues and expenses of a subsidiary acquired or disposed of during the fiscal year are included in the results from the date the Company obtains control until the date when the Company ceases to control the subsidiary.

 

The subsidiary's financial statements have been prepared for the same reporting date as the parent company.

 

All intragroup balances, revenues, expenses, and unrealized gains and losses from intragroup transactions have been eliminated. Other comprehensive results of the parent company, where applicable, will be directly recorded in the Company’s equity, under “other comprehensive results”.

 

As of December 31, 2023, SABESP held 100% of direct interest in Sabesp Olímpia S/A.

 

3.2

Cash and cash equivalents

 

Cash and cash equivalents include cash in hand, bank deposits, overdraft accounts, and other short-term highly liquid investments with maturities and intention of use by the Company’s Management in a period lower than three months.

 

3.3

Financial assets and liabilities

 

Financial assets - Classification

 

The Company classified its financial assets according to the following categories: measured at amortized cost, measured at fair value through other comprehensive income, and measured at fair value through profit or loss. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of the financial assets at inception. As of December 31, 2023 and 2022, the Company did not have financial assets classified as fair value through other comprehensive income and fair value through profit or loss.

 

·

Amortized cost

 

This category includes financial assets that meet the following conditions (i) assets held within the business model to hold financial assets to collect contractual cash flows; and (ii) the contractual terms of the financial asset give rise, on specified dates, to cash flows that are solely payments of principal and interest on the principal amount outstanding.

Presented as current assets, except for those with a maturity of more than 12 months after the reporting date, which are classified as noncurrent assets. The Company's financial assets measured at amortized cost include cash and cash equivalents, financial investments, restricted cash, balances of trade receivables, accounts receivable from related parties, other assets and receivables from the Water and Basic Sanitation National Agency (ANA). Financial assets measured at amortized cost are recorded at fair value and subsequently at amortized cost, under the effective interest rate method, except for trade receivables, which are initially measured at transaction price, as it contains no financing items, and are subsequently measured at amortized cost.

 

Financial liabilities - Classification

 

The Company classifies its financial liabilities measured at amortized cost. The classification depends on the purpose for which the financial liabilities were assumed. This category includes balances payable to contractors and suppliers, borrowings and financing, services payable, balances payable from Public-Private Partnerships (PPP), and program contract commitments.

 

The effective interest rate method is adopted to calculate the amortized cost of a financial liability and allocate its interest expense under the respective period. The effective interest rate exactly deducts the estimated future cash flows (including fees, transaction costs, and other issue costs) over the estimated life of the financial liability or, when appropriate, during a shorter period, for the initial recognition of the net carrying amount.

 

Impairment of financial assets

 

·                  Accounts receivable

 

Due to the characteristics of the Company’s accounts receivable such as (i) insignificant financial component; (ii) non-complex receivables portfolio; and (iii) low credit risk, the simplified approach of expected credit loss was adopted - it consists of recognizing the expected credit loss based on the asset’s useful life.

 

The methodology to calculate the allowance for doubtful accounts consisted of using an estimate calculated based on the average default observed in the last 36 months, per maturity range, in addition to estimating the recovery of credits overdue for more than 360 days, based on the track record of the last three years. It also considered the category of private and public customers and segregated accounts receivable among the regular consumption accounts and agreements. The Company also concluded that the estimates of the macroeconomic indicators Gross Domestic Product (GDP), Unemployment Rate, and the Extended Consumer Price Index (IPCA) were not impacted, given that it carried out correlation analyses of these indicators and their default history, which did not result in a significant correlation between them.

·                  Deposit transactions and financial investments measured at amortized cost

 

The Company analyzes changes in the rates of investments in bank deposit certificates and information obtained from regulatory agencies about the financial institutions. The likelihood of delinquency over 12 months was based on historical data provided by credit rating agencies for each credit level and analyzed in terms of sensitivity based on current returns.

 

These deposits and financial investments are subject to an insignificant risk of change in value.

 

3.4

Operating income

 

(a)

Revenue from sanitation services

 

Revenue from water supply and sanitation services are recognized as water is consumed and services are provided. Revenues, including unbilled revenues, are recognized at the fair value of the consideration received or receivable for the rendering of those services. Revenue is shown net of value-added tax, rebates, and discounts. Unbilled revenues represent incurred revenues in which the services were provided but not yet billed until the end of each period, and are recorded as trade receivables based on monthly estimates of the completed services.

 

Revenues are recognized based on CPC 47 / IFRS 15 – Revenue from Contracts with Customers, which establishes a five-step model applicable to revenue from a contract with a customer. Revenues are recognized when: i) it identifies contracts with customers; ii) it identifies the different contract obligations; iii) it determines the transaction price; iv) it allocates the transaction price to the performance obligations in the contracts; and (v) it satisfies all performance obligations. Disputed amounts are recognized as revenue when collected.

 

(b)

Construction revenue

 

Revenue from construction is recognized in accordance with ICPC 01 (R1) / IFRIC 12 (Service Concession Arrangements) and CPC 47/IFRS 15 (Revenue from Contracts with Customers), as all performance obligations are satisfied over time. During the construction of the contract, an asset is classified as a contract asset, in which the Company estimates that the fair value of its consideration is equivalent to expected construction costs plus margin. The fee represents the additional margin related to the work performed by the Company in relation to such construction contracts and it is added to construction costs, resulting in the construction revenue.

 

3.5

Trade receivables and allowance for doubtful accounts

 

Trade receivables are amounts due from customers for services performed in the ordinary course of business. These are classified as current assets, except when maturity exceeds 12 months after the end of the reporting date, when they are presented as noncurrent assets.

 

The Company establishes an allowance for doubtful accounts for receivable balances at an amount that Management considers to be sufficient to cover eventual losses, as described in Note 3.3.

3.6

Inventories

 

Inventories comprise supplies for consumption and maintenance of the water and sewage systems and are stated at the lowest between the average cost of acquisition or realizable value and are classified in current assets.

 

3.7

Investment properties

 

Investment properties are recorded at the acquisition or construction cost, less accumulated depreciation, except for the land group, calculated by the straight-line method at rates that consider the estimated useful life of the assets. Expenditures related to repairs and maintenance are recorded in the income statement when incurred.

 

The Company also maintains some assets for undetermined use in the future, i.e. it is not defined whether they will be used in the operation or sold in the short term during the ordinary course of business.

 

3.8

Contract Asset

 

Contract Asset (works in progress) is the right to consideration in exchange for goods or services transferred to customers. As established by CPC 47 – Revenue from Contracts with Customers, assets subject to the concession under construction, recorded under the scope of ICPC 01 (R1) – Concession Agreements, must be classified as Contract Asset during the construction period and transferred to Intangible Assets after the conclusion of the works.

 

A Contract Asset is recognized at fair value, including the capitalization of labor, construction margin, interest, and other financial charges capitalized during the construction period of qualifying assets, where applicable, based on the weighted average rate of borrowings in effect on the capitalization date. A qualifying asset necessarily requires a substantial period, established by the Company as being higher than 12 months, to be ready for use, considering the completion period of the works, given that most of them take on average more than 12 months to be completed, which corresponds to one fiscal year of the Company.

 

The infrastructure construction values are recognized as revenue, at fair value, provided that they generate future economic benefits. The accounting policy to recognize construction revenue is described in Note 3.4 (b).

3.9

Property, plant, and equipment

 

Property, plant, and equipment comprise mainly administrative facilities not composing the assets subject to the concession agreements. Those assets are stated at acquisition or construction cost less depreciation and impairment losses, as applicable. Where applicable, interest, other finance charges, and inflationary effects resulting from financing effectively applied to construction in progress are recorded as the cost of the respective property, plant, and equipment for the qualifying assets. A qualifying asset necessarily requires a substantial period, established by the Company as being higher than 12 months, to be ready for use, considering the completion period of the works, given that most of them take on average more than 12 months to be completed, which corresponds to one fiscal year of the Company.

 

Subsequent costs are included in the existing asset's carrying amount or recognized as a separate asset, as appropriate, only when it is probable that the future economic benefit associated with the item will flow to the Company and the cost of the item can be reliably measured. Repairs and maintenance are charged to the income statement of the year, as incurred.

 

The depreciation of property, plant, and equipment begins when such an item becomes available for use, in its location, and under the necessary condition when this asset becomes operational. Depreciation is calculated using the straight-line method and the average rates are presented in Note 16 (a). Land is not depreciated.

 

The useful lives of assets are revised and adjusted, where applicable, at the end of each year.

 

Gains and losses on disposals are determined by the difference between the sales value and residual book balance and are recognized in profit or loss, under other operating income (expenses).

 

3.10

Intangible assets

 

Intangible assets are those arising from concession contracts, and the main costs are transferred from the Contract Asset, as described in Note 3.8.

 

The amortization of an intangible asset begins when it becomes available for use, in its location and necessary condition, when this asset becomes operational. The amortization reflects the period in which it is expected that the asset’s future economic benefits are consumed by the Company, which may be the final term of the concession or their useful life.

 

The amortization of intangible assets ends when the asset is fully consumed or written off, whatever occurs first.

 

Donations in assets received from third parties and government entities to allow the Company to render water supply and sewage services are not recorded in the financial statements at zero cost, since these assets are owned by the granting authority.

 

Financial resources received as donations for infrastructure construction are recorded under “Other operating income”.

(a)

Concession agreements/program contracts/service contracts

 

The Company operates concession agreements including the rendering of basic sanitation, environmental, water supply, and sewage services, signed with the granting authorities. The infrastructure used by SABESP related to service concession agreements is considered to be controlled by the granting authority when:

 

(i)

The granting authority controls or regulates what services the operator must provide with the infrastructure, to whom it must provide them, and at what price; and

(ii)

The granting authority controls the infrastructure, i.e. retains the right to take back the infrastructure at the end of the concession.

 

The rights over the infrastructure operated under the concession agreements are accounted for as an intangible asset as the Company has the right to charge for the use of the infrastructure assets, and the users (consumers) must pay for the services.

 

Intangible assets related to the concessions are amortized on a straight-line basis over the contract period or useful life of the underlying asset, the lowest of them.

 

The details referring to the amortization of intangible assets are described in Note 15 (c).

 

(b)

Software license of use

 

Software licensing is capitalized based on acquisition costs and other implementation costs. Amortizations are recorded according to the useful life and the expenses associated with maintaining them are recognized in profit or loss when incurred.

 

3.11

Impairment of non-financial assets

 

Property, plant, and equipment, intangible assets, and other noncurrent assets with defined useful lives are reviewed for impairment on an annual basis, or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company does not have assets with indefinite useful life and assessed that there are no indications of impairment losses, mainly supported by Law 14,026/2020, which ensures economic and financial sustainability to public sanitation services through tariffs or indemnity.

3.12

Trade payables and contractors

 

Trade payables and contractors are obligations to pay for goods or services acquired from suppliers in the ordinary course of business and are initially measured at fair value, which generally corresponds to the bill, and subsequently at amortized cost, being classified as current liabilities, except when the maturity exceeds 12 months after the reporting date, being presented as noncurrent liabilities.

 

3.13

Borrowings and financing

 

Borrowings and financing are initially recognized at fair value, upon receipt of funds, net of transaction costs, and stated at amortized cost. See Note 17. Borrowings and financing are classified as current liabilities unless the Company has an unconditional right to defer the settlement of the liability for at least 12 months after the reporting date.

 

The bonds issued by the Company are not convertible into shares and are recorded similarly to borrowings.

 

3.14

Borrowing costs

 

Borrowing costs consist of interest rates and other charges incurred by the Company and arise from borrowing and financing agreements, including exchange variation.

 

Costs attributable to the acquisition, construction, or production of an asset, which, necessarily, requires a substantial time to be ready for use or sale are capitalized as part of the cost of these assets. Other borrowing costs are recognized as expenses in the period they are incurred. The capitalization occurs during the construction period of the asset, considering the weighted average rate of borrowings effective on the capitalization date.

 

The Company analyses foreign currency-denominated borrowings or financing as if they were contracted in local currency, restricting the capitalization of interest and/or exchange variation by the amount that would be capitalized if they were contracted in the domestic market in similar lines of credit and loans.

 

3.15

Salaries, payroll charges, and social contributions

 

Salaries, vacations, Christmas bonuses, profit sharing, and additional payments negotiated in collective labor agreements plus related charges and contributions are recorded on an accrual basis.

 

The profit-sharing plan is based on operational and financial targets, and a provision is created when it is contractually required or when there is a past practice that created a constructive obligation and is recorded as operating cost, selling and administrative expenses, or capitalized in assets.

3.16

Provisions, legal obligations, escrow deposits, and contingent assets

 

Provisions are recognized when: i) the Company has a present (legal or constructive) obligation resulting from a past event; ii) an outflow of resources that comprise economic benefits will probably be required to settle the obligation; and iii) the amount can be reliably estimated. Where there are several similar obligations, the likelihood that an outflow of resources will be required to settle an obligation is determined by considering the nature of these obligations as a whole.

 

Provisions are measured at the present value of the disbursements expected to be required to settle an obligation using a pre-tax rate that reflects the current market assessments of the time value of money and the risks specific to the obligation. The increase in the obligation due to the passage of time is recognized as a financial expense.

 

For financial statement presentation purposes, the provision is stated net of escrow deposits, based on the legal offset right.

 

Escrow deposits not linked to the related obligations are recorded in noncurrent assets and adjusted by the indexes defined by the competent authorities.

 

The Company does not recognize contingent liabilities in the financial statements since it either does not expect outflows to be required or the amount of the obligation cannot be reliably measured.

 

Contingent assets are not recognized in the financial statements.

 

3.17

Environmental costs

 

Costs related to ongoing environmental programs are expensed in the income statement when there is a taxable event. Ongoing programs are designed to minimize the environmental impact of the operations and to manage the environmental risks inherent to the Company's activities.

3.18

Current and deferred income tax and social contribution

 

Income tax expenses comprise current and deferred income tax and social contributions.

 

Current taxes

 

The provision for income tax and social contribution is calculated based on the taxable profit for the year and the rates effective at the end of the year. The income tax was defined at a rate of 15%, plus a 10% surtax on taxable income exceeding R$ 240. The social contribution was defined at a rate of 9% over the adjusted net income. Taxable income differs from net income (profit presented in the income statement) because it excludes income or expenses taxable or deductible in other years, and excludes items not permanently taxable or not deductible. The Company periodically evaluates the positions taken in the income tax return regarding situations in which the applicable tax regulations are subject to interpretation. It establishes provisions, where appropriate, based on amounts expected to be paid to the tax authorities.

 

Deferred taxes

 

Deferred taxes are fully recognized on temporary differences arising between the tax basis of assets and liabilities and their carrying amounts in the financial statements. However, deferred taxes are not accounted for if they arise from the initial recognition of an asset or liability in a transaction that does not affect the tax basis, except in business combinations. Deferred taxes are determined using tax rates (and laws) effective at the end of the reporting period and are expected to be applied when the related income tax and social contribution are realized.

 

Deferred tax assets are recognized only to the extent that it is probable that future taxable profit will be available for which temporary differences can be used and tax losses can be offset.

 

Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when deferred income tax assets and liabilities are related to income taxes levied by the same tax authority over the tax entity.

 

3.19

Taxes on revenues

 

Revenues from sanitation services are subject to Pasep (Public Servant Fund) and Cofins (Contribution for Social Security Financing) rates of 1.65% and 7.60%, except for financial revenues that are calculated at the rates of 0.65% and 4.00%, respectively.

 

Pasep and Cofins taxes incident on billed amounts to public entities are due when the bills are received.

 

These taxes are calculated by the regime of noncumulative taxation and presented net of the corresponding credits, such as deductions from gross revenues. The lines “other operating income” and “financial revenues” are presented net of such taxes on the income statement.

 

In addition, revenues from sanitation services are also subject to the Regulatory, Control, and Oversight Fee (TRCF), whose taxable event is the performance of regulatory, control, and monitoring activities by ARSESP, calculated at 0.50% of the annual revenue directly generated by the service provided less taxes levied on the service.

 

3.20

Pension plan obligations

 

(a)

Defined benefit

 

The Company makes contributions to defined benefit plans sponsored by it on a contractual basis. Regular contributions comprise the net administrative expenses and are recognized in the result of the period in which they are due.

 

Pension plan liabilities correspond to the present value of the obligation on the reporting date, less the fair value of the plan’s assets. The defined benefit obligations (G1), as well as the additional retirement and pension plan (G0), are calculated on an annual basis by independent actuaries, using the projected unit credit method. The estimated future cash outflows are discounted to their present value, using the interest rates of Government bonds with maturities that approximate those of the related liability.

 

Regarding actuarial gains and losses arising from adjustments based on the experience and changes in actuarial assumptions are directly recorded under equity, as other comprehensive income (OCI), so that the plan's net asset or liability is recognized in the statement of financial position to reflect the full amount of plan’s deficit or surplus.

 

In the event of curtailment or settlement of the plan, related to only some of the employees covered by the plan, or where only part of an obligation is settled, the gain or loss includes a proportional share of the past service cost and actuarial gains and losses. The proportional share is determined based on the present value of the obligations before and after the curtailment or settlement.

 

(b)

Defined contribution

 

The Company makes contributions to defined benefit plans sponsored by it on a contractual basis, which provides post-employment benefits to its employees, in which the Company makes equal contributions to employees, within the limits set by regulation. In this model, the benefits paid are directly related to the amount contributed, with no deficits to be covered by the Company.

 

3.21

Financial income (expenses)

 

Financial income is primarily comprised of interest and inflation adjustments resulting from financial investments, escrow deposits, and negotiations with customers to pay by installments, calculated using the effective interest rate method.

 

Financial expenses refer to interest, inflation adjustments, and exchange variation mainly on borrowings and financing, provisions, public-private partnership, and program contract commitments, and are calculated using the effective interest rate method.

Inflation adjustment gains and losses arise from the collection or payment to third parties, as contractually required by law or court decision, recognized on an accrual basis pro rata temporis. Inflation adjustments included in the agreements are not considered embedded derivatives, since they are deemed as inflation indexes for the Company’s economic scenario.

 

3.22

Lease

 

Leases are recognized at the present value of the contractual obligations, presented in assets as Right of Use (Note 15 (f)) and in liabilities as Leases (Note 17 (b)), except for short-term contracts (12 months or less) and/or low-value contracts (below US$ 5,000), which are recorded as expenses when incurred.

 

3.23

Other current and noncurrent assets and liabilities

 

Other assets are recorded at acquisition cost, net of any impairment loss, where applicable. Other liabilities are recorded at known or estimated amounts, including, where applicable, related financial charges.

 

3.24

Dividends and interest on capital

 

The Company uses the tax benefit of distributing dividends as interest on capital, as permitted by law and based on the Bylaws. Interests are accounted for under Law 9,249/1995 for tax-deductibility purposes, limited to the daily pro rata variation of the long-term interest rate (TJLP). The benefit attributed to shareholders is recognized in current liability against Equity. Any amount over the minimum mandatory is recognized when approved by shareholders in the General Meeting, except for taxes incurring in the distribution of interest on capital. The tax benefit of interest on capital is accrued in the profit/loss of the year, under the same recognition basis of expenses.

3.25

Present value adjustment

 

Current and noncurrent financial assets and liabilities arising from long- or short-term transactions are adjusted to present value based on market discount rates as of the transaction date, when the effects are significant.

 

3.26

Value added statement (DVA)

 

The purpose of the value added statement is to present the wealth generated and distributed by the Company, as required by the accounting practices adopted in Brazil, as supplementary information to the financial statements for purposes of IFRS.

 

The DVA was prepared based on information obtained in the accounting books that are the base for preparing the financial statements. The first part presents the wealth generated by the Company, represented by revenues, inputs acquired from third parties and retentions, and the wealth received in transfer, represented by the equity result and financial income. The second part presents the distribution of wealth segregated into employees, taxes, fees, and contributions, value distributed to providers of capital, and value distributed to shareholders.

 

3.27

Segment information

 

Operating segments are determined in a manner consistent with the internal reporting to the Company’s chief operating decision maker (“CODM”), which, in the case of SABESP, is comprised of the Board of Directors and the Board of Executive Officers, to make strategic decisions, allocate resources and evaluate performance.

 

The Company determined that it has one operating segment which is sanitation services.

 

The accounting policies used to determine segment information are the same as those used to prepare the Company’s financial statements.

 

The measurement of the result per segment is the profit from operations before other net operating expenses and equity accounting, which excludes construction costs and revenue.

 

The CODM analyzes asset and liability information on a consolidated basis. Consequently, the Company does not disclose segregated information on assets and liabilities.

 

Substantially all noncurrent assets and revenue generated from customers are located in the São Paulo State. Consequently, financial information is not disclosed by geographic area.

3.28

Foreign currency translation

 

(a)

Functional and reporting currency

 

Items included in the financial statements are measured using the currency of the main economic environment in which the company operates ("the functional currency"). The financial statements are presented in Brazilian reais (R$), which is also the Company's functional currency. All financial information has been presented in Brazilian reais and rounded to the next thousand, except where otherwise indicated.

 

(b)

Foreign currency translation

 

Foreign currency-denominated transactions are translated into Brazilian reais using the exchange rates prevailing on the transaction dates. Statements of financial position balances are translated by the exchange rate prevailing on the reporting date.

 

Exchange gains and losses resulting from the settlement of these transactions and the translation of foreign currency-denominated monetary assets and liabilities are recognized in the income statement, except for borrowings and financing referring to property, plant, and equipment, or intangible assets in progress, where exchange losses are recognized as corresponding entry to the asset while construction is in progress, as described in Note 3.14.

Changes in accounting practices and disclosures

 

4.1

New standards, amendments, and interpretations effective for periods beginning on or after January 01, 2023

 

CPC 50 / IFRS 17 – Insurance Contracts – The Company does not have contracts that meet the definition of insurance contract according to this Standard.

 

The amendments to CPC 26 (R1) / IAS 1 – Presentation of Financial Statements and IFRS Practice Statement 2 – Making Materiality Judgements; CPC 32 / IAS 12 – Income Taxes – Deferred Tax Related to Assets and Liabilities Arising from a Single Transaction (“single transaction”); CPC 32 / IAS 12 – Income Taxes – International Tax Reform – Pillar Two Model Rule; CPC 23 / IAS 8 - Accounting Policies, Changes in Estimates and Correction of Errors — Definition of Accounting Estimates, did not impact the disclosures or amounts recognized in the annual financial statements.

 

 

4.2

New standards, amendments, and interpretations of existing standards that are not yet effective

 

The Company did not early adopt these standards and is assessing the impacts of the new and revised IFRS below on the disclosures or amounts recognized in the financial statements:

 

Standard	Description	Impact
Amendments to CPC 36 (R3) / IFRS 10 – Consolidated Statements and CPC 18 (R2) / IAS 28 – Sales or Contributions of Assets between an Investor and its Associate or Joint Venture2	Clarify situations that involve the sale or contribution of assets between an investor and its associate or joint venture.	The Company is assessing the impacts and effects of the amendments; however, it does not expect any effects from the amendments.
Amendments to CPC 26 (R1) / IAS 1 – Classification of Liabilities as Current or Noncurrent1	These amendments to CPC 26 (R1) / IAS 1 only affect the presentation of liabilities as current or noncurrent in the statement of financial position and not the amount or time of recognition of any asset, liability, income, or expense, or information disclosed on such items. In addition, they clarify that the classification of liabilities as current or noncurrent is based on rights existing on the balance sheet date, specify that classification is not affected by the expectations on whether an entity will exercise its right to defer the settlement of the liability, and introduce the definition of ‘settlement’ to clarify that settlement refers to the transfer, to a counterparty, of cash, equity instruments, other assets or services.	The Company does not expect any impacts from this standard.
Amendments to CPC 03 (R2) / IAS 7 – Statement of Cash Flows and CPC 40 (R1) / IFRS 7 – Financial Instruments: Disclosure1	The amendments add a disclosure objective in CPC 03 (R2) / IAS 7 stating that information about their supplier financing arrangements should be disclosed to allow users of the financial statements to assess the effects of these agreements on the entity’s liabilities and cash flows. Additionally, CPC 40 (R1) / IFRS 7 was amended to include supplier financing arrangements as an example within the requirements for disclosing information about the entity’s exposure to liquidity risk concentration.	The Company does not expect effects from these amendments.

Amendments to CPC 06 (R2) / IFRS 16 – Leases – Lease liability in a “Sale and Leaseback” transaction1

The amendments to CPC 06 (R2) / IFRS 16 add subsequent measurement requirements for sale and leaseback transactions that meet the requirements of CPC 47 / IFRS 15 for accounting purposes as a sale. The amendments require that the seller-lessee determine “lease payments” or “revised lease payments” so that the seller-lessee does not recognize a gain or loss related to the right-of-use retained by the seller-lessee after the commencement date.   The amendments do not impact the gain or loss recognized by the seller-lessee related to the total or partial termination of a lease. Without these new requirements, a seller-lessee may have recognized a gain on the right-of-use retained solely because of the remeasurement of the lease liability (for instance, after a modification or change in the lease term) that applies the general requirements in CPC 06 (R2) / IFRS 16. This may have been particularly the case in a sublease that includes variable lease payments not dependent on an index or rate.

The Company does not expect effects from these amendments.

 

1.

Effective for annual periods beginning on or after January 01, 2024.

2.

The effective date of the amendments has not yet been defined by IASB.

 

There are no other standards and interpretations not yet adopted that may, in the opinion of Management, have a significant impact on the result for the year of equity disclosed by the Company in its financial statements.

Risk management

 

5.1

Financial Risk Management

 

Financial risk factors

 

The Company's activities are affected by the Brazilian economic scenario, making it exposed to market risk (exchange rate and interest rate), credit risk, and liquidity risk. Financial risk management is focused on the unpredictability of financial markets and seeks to minimize potential adverse effects on financial performance.

 

The Company has not utilized derivative instruments in any of the reported periods.

 

(a)

Market risk

 

Foreign currency risk

 

Foreign exchange exposure implies market risks associated with currency fluctuations since the Company has foreign currency-denominated liabilities, arising from long-term funding, in development institutions, at more attractive interest rates, in U.S. dollars and Yen.

 

The management of currency exposure considers several current and projected economic factors, besides market conditions.

 

This risk arises from the possibility that the Company may incur losses due to exchange rate fluctuations that would impact liability balances of foreign currency-denominated borrowings and financing and related financial expenses. The Company does not maintain hedge or swap contracts or any derivative financial instrument to hedge against this risk.

 

Part of the financial debt, totaling R$ 2,785,853 as of December 31, 2023 (R$ 2,809,441 as of December 31, 2022), is indexed to the U.S. dollar and Yen. The exposure to exchange risk is as follows:

	Parent Company and Consolidated		Parent Company
	December 31, 2023		December 31, 2022
	Foreign currency (in thousands)	R$	Foreign currency (in thousands)	R$
Borrowings and financing – US$	280,188	1,356,474	191,022	996,695
Borrowings and financing – Yen	41,078,385	1,405,702	45,369,189	1,795,259
Interest and charges from borrowings and financing – US$		15,510		6,985
Interest and charges from borrowings and financing – Yen		8,167		10,502
Total exposure		2,785,853		2,809,441
Borrowing cost – US$		(37,520)		(31,037)
Borrowing cost – Yen		(2,442)		(2,646)
Total foreign currency-denominated borrowings (Note 17)		2,745,891		2,775,758

 

The 1.1% decrease in the balance of the foreign currency-denominated debt from December 31, 2023, compared to December 31, 2022, was mainly impacted by the depreciation of the US dollar and Yen against the Brazilian real. The table below shows the prices and exchange variations in the period:

 

	December 31, 2023	December 31, 2022	Var.
US$	R$ 4.8413	R$ 5.2177	-7.2%
Yen	R$ 0.03422	R$ 0.03957	-13.5%

 

Borrowings and financing fell by R$ 309,854 in 2023 (a decrease of R$ 488,614 in 2022), see Note 17 (ii). As of December 31, 2023, if the Brazilian real had depreciated or appreciated by 10 percentage points, in addition to the impacts already mentioned above, against the U.S. dollar and Yen with all other variables held constant, the effects on the result before funding costs in the year would have been R$ 278,586 in 2023 (R$ 280,944 in 2022), lower or higher.

 

The probable scenario below presents the effect on the income statements for the next 12 months, considering the projected rates of the U.S. dollar and the Yen.

 

The Company understands that the scenario presented is reasonable, given the instability of the Brazilian real against the U.S. dollar and the Yen.

 

 

	Parent Company and Consolidated
	Probable scenario

Net currency exposure as of December 31, 2023 in US$ - Liabilities	280,188

Total effect on the net financial result in R$ - (loss)	(113,478)
(*) For the probable scenario in U.S. dollars and Yen, the exchange rates estimated for December 31, 2024 were used, according to the Focus-BACEN and B3’s Benchmark Rate report, of December 31, 2023, respectively.

 

Interest rate risk

 

This risk arises from the possibility that the Company could incur losses due to fluctuations in interest rates, increasing the financial expenses related to borrowings and financing.

 

The Company has not entered into any derivative contract to hedge against this risk; however, it continually monitors market interest rates, to evaluate the possible need to replace its debt.

The table below provides the borrowings and financing subject to different inflation adjustment indices:

 

	Parent Company and Consolidated	Parent Company
	December 31, 2023	December 31, 2022
CDI (i)	9,966,111	9,251,150
TR (ii)	1,684,711	1,635,587
IPCA (iii)	3,038,378	3,073,435
TJLP (iv)	1,365,806	1,433,029
SOFR (v)	1,356,473	996,697
Interest and charges	392,906	424,856
Total	17,804,385	16,814,754

 

(i)	CDI - (Certificado de Depósito Interbancário), an interbank deposit certificate

(ii)	TR – Interest Benchmark Rate

(iii)

IPCA - (Índice Nacional de Preços ao Consumidor Amplo), a consumer price index

(iv)	TJLP - (Taxa de Juros a Longo Prazo), a long-term interest rate index

(v)	SOFR - Secured Overnight Financing Rate

 

Another risk to which the Company is exposed is the mismatch of inflation adjustment indices of its debts with those of its service revenues. Tariff adjustments of services provided do not necessarily follow the increases in the inflation indexes to adjust borrowings, financing, and interest rates affecting indebtedness.

 

As of December 31, 2023, if interest rates on borrowings and financing had been 1 percentage point higher or lower with all other variables held constant, the effects on profit before taxes for the year would have been R$ 178,044 (R$ 168,148 in 2022), lower or higher, mainly as a result of lower or higher interest expense on floating rate borrowings and financing.

 

(b)

Credit risk

 

Credit risk is related to cash and cash equivalents, financial investments, as well as credit exposures to wholesale basis and retail customers, including accounts receivable, restricted cash, and accounts receivable from related parties. Credit risk exposure to customers is mitigated by sales to a dispersed base.

 

The maximum exposure to credit risk as of December 31, 2023 is the carrying amount of instruments classified as cash and cash equivalents, financial investments, restricted cash, trade receivables, and accounts receivable from related parties in the balance sheet date. See additional information in Notes 7, 8, 9, 10, and 11.

Regarding the financial assets held with financial institutions, the credit quality was assessed by reference to external credit ratings (if available) or historical information about the bank’s default rates. For the credit quality of the banks, such as deposits and financial investments, the Company assesses the rating published by three main international agencies (Fitch, Moody’s, and S&P), as follows:

 

Banks	Fitch	Moody's	Standard Poor's
Banco do Brasil S/A	AAA(bra)	AAA.br	-
Banco Santander Brasil S/A	-	AAA.br	brAAA
Brazilian Federal Savings Bank	AAA(bra)	AAA.br	brAAA
Banco Bradesco S/A	AAA(bra)	AAA.br	brAAA
Banco Itaú Unibanco S/A	AAA(bra)	AAA.br	-
Banco BV	-	AA.br	brAAA
Banco BTG Pactual S/A	AAA(bra)	AAA.br	brAAA

 

The rating assessment disclosed by Fitch for deposit transactions and financial investments in local currency is as follows:

 

	Parent Company		Consolidated
	December 31, 2023	December 31, 2022	December 31, 2023
Cash and cash equivalents and financial investments
AA(bra)	-	2,237,629	-
AAA(bra)	2,939,713	1,011,685	2,940,690
Others (*)	324,546	296,044	324,546
	3,264,259	3,545,358	3,265,236

 

(*) As of December 31, 2023, this category includes R$ 322,241 (R$ 289,908 as of December 31, 2022) referring to Banco BV, current accounts, and financial investments, which are not rated by Fitch.

 

(c)

Liquidity risk

 

Liquidity is primarily reliant upon cash provided by operating activities and borrowings and financing obtained in the local and international capital markets, as well as the payment of debts. The management of this risk considers the assessment of its liquidity requirements to ensure it has sufficient cash to meet its operating and capital expenditures needs.

 

The funds held are invested in interest-bearing current accounts, time deposits, and securities, with instruments with appropriate maturity or liquidity sufficient to provide margin as determined by the projections mentioned above.

The table below shows the financial liabilities, by maturity, including the installments of principal and future interest. For agreements with floating interest rates, the interest rates used correspond to the base date of December 31, 2023.

Cross default

 

The Company has borrowings and financing agreements including cross-default clauses, i.e., the early maturity of any debt may imply the early maturity of these agreements. The indicators are continuously monitored to avoid the execution of these clauses, and the most restrictive ones are shown in Note 17 (c).

 

(d)

Sensitivity analysis on interest rate risk

 

The table below shows the sensitivity analysis of the financial instruments, prepared under CPC 40 (R1) to evidence the balances of main financial assets and liabilities, calculated at a rate projected for the twelve-month period after December 31, 2023, or until the final settlement of each contract, whichever occurs first, considering a probable scenario.

 

The purpose of the sensitivity analysis is to measure the impact of changes in the market on the financial instruments, considering constant all other variables. At the time of settlement, the amounts can be different from those presented, due to the estimates used in the measurement.

5.2

Capital management

 

The Company’s objectives when managing capital are to ensure it continues to increase investments in infrastructure, provide returns for shareholders and benefits for other stakeholders, and maintain an optimal capital structure to reduce the cost of capital.

 

Capital is monitored based on the leverage ratio, which corresponds to net debt divided by total capital (shareholders and providers of capital). Net debt corresponds to total borrowings and financing less cash and cash equivalents and financial investments. Total capital is calculated as total equity plus net debt, as shown in the statement of financial position.

 

	Parent Company		Consolidated
	December 31, 2023	December 31, 2022	December 31, 2023
Total borrowings and financing (Note 17)	19,536,350	18,958,671	19,536,350
(-) Cash and cash equivalents (Note 7)	(838,338)	(1,867,485)	(838,484)

Leverage ratio	35%	36%	35%

 

 

5.3

Fair value estimates

 

The Company considers that balances from trade receivables (current) and trade payables by carrying amount less impairment approximate their fair values, considering the short maturity. Long-term trade receivables also approximate their fair values, as they will be adjusted by inflation and/or will bear contractual interest rates over time.

5.4

Financial instruments

 

The Company did not have financial assets classified as fair value through other comprehensive income and fair value through profit or loss. The financial instruments included in the amortized cost category comprise cash and cash equivalents, financial investments, restricted cash, trade receivables, balances with related parties, other assets and balances receivable from the Water National Agency (ANA), accounts payable to suppliers, borrowings and financing, services payable, balances payable deriving from the Public-Private Partnership (PPP) and program contract commitments, which are non-derivative financial assets and liabilities with fixed or determinable payments, not quoted in an active market, except for cash equivalents and financial investments.

 

The estimated fair values of the financial instruments were as follows:

Additionally, SABESP has financial assets receivable from related parties, totaling R$ 1,196,545 as of December 31, 2023 (R$ 1,156,743 as of December 31, 2022), which were calculated under the conditions negotiated between the related parties. The conditions and additional information related to these financial instruments are disclosed in Note 11. Part of this balance, totaling R$ 1,076,174 (R$ 1,060,040 as of December 31, 2022), refers to reimbursement of additional retirement and pension plan - G0, indexed by IPCA plus simple interest of 0.5% p.m. On the transaction date, this interest rate approximated that of National Treasury Notes (NTN-b), with a term similar to the terms of related-party transactions.

Public-Private Partnership - PPP	3,286,614	3,286,614

 

The criteria adopted to obtain the fair values of borrowings and financing are as follows:

 

(i)

Agreements with CEF (Brazilian Federal Savings Bank) were projected until their final maturities, at the average interest rate plus TR x DI and the average contractual term, were adjusted to present value by a funding rate specific for the Company in similar contracts, plus TR x DI, on the end of the reporting period. TR x DI rates were obtained with B3.

 

(ii)

The debentures were projected up to the final maturity date according to contractual rates (IPCA, DI, TJLP, or TR), and adjusted to present value considering the future interest rate published by ANBIMA in the secondary market, or by equivalent market rates, or the Company’s shares traded in the Brazilian market.

 

(iii)

Financing – BNDES corresponds to instruments valued at their carrying amount restated until the maturity date, and are indexed by the long-term interest rate (TJLP).

 

These financings have specific characteristics and conditions defined in the financing agreements with BNDES, between independent parties, and reflect the conditions for these types of financing. Brazil does not have a consolidated market of long-term debts with the same characteristics of BNDES financing; thus, the offering of credit to entities in general, with such long-term characteristics, is usually restricted to BNDES.

 

(iv)

Other financings in local currency are considered by the carrying amount restated until the maturity date, adjusted to present value at future market interest rates. The future rates used were obtained on the website of B3.

 

(v)

Agreements with IDB and IBRD were projected until final maturity in origin currency, using the contracted interest rates plus SOFR’s future rate, obtained with Bloomberg, adjusted to present value using the exchange coupon curve obtained with B3, plus future LFT, disclosed by ANBIMA in the secondary market. All the amounts obtained were translated into Brazilian reais at the exchange rate of December 31, 2023.

 

(vi)

Agreements with JICA were projected until final maturity in origin currency, using the contracted interest rates, translated to the U.S. dollar and adjusted to present value using the exchange coupon curve obtained with B3, plus future LFT, disclosed by ANBIMA in the secondary market. The amounts obtained were translated into Brazilian reais at the exchange rate of December 31, 2023.

 

(vii)

Lease and finance leases based on IFRS 16 correspond to instruments valued at their present value. Thus, the Company discloses the amount recorded as of December 31, 2023, as market value.

 

Financial instruments referring to financial investments and borrowings and financing are classified as Level 2 in the fair value hierarchy.

 

Considering the nature of other financial instruments, assets, and liabilities, the balances recognized in the statement of financial position approximate the fair values, except for borrowings and financing, considering the maturities close to the end of the reporting date, comparison of contractual interest rates with market rates in similar operations at the end of the reporting period, their nature, and maturity terms.

Key accounting estimates and judgments

 

The preparation of the financial statements requires Management to disclose judgments (except for those that involve estimates) that have a significant impact on the amounts recognized based on experience and other factors deemed as relevant, which affect the values of assets and liabilities and present results that may differ from the actual results.

 

The Company establishes estimates and assumptions regarding the future, which are reviewed on a timely basis. Such accounting estimates, by definition, may differ from the actual results. The effects arising from the reviews of the accounting estimates are recognized in the period in which the estimates are reviewed.

 

6.1

Main judgments in applying the accounting policies

 

The Company assessed the main accounting policies that involve judgments, except for those that involve estimates, and concluded that none of them have a significant effect.

 

6.2

Main sources of uncertainties in the estimates

 

The areas that require a higher level of judgment and greater complexity, as well as assumptions and estimates that are significant for the financial statements, are disclosed as follows:

 

(a)    Allowance for doubtful accounts

 

The Company establishes allowance for doubtful accounts in an amount that Management considers sufficient to cover expected losses (see Note 10 (c)), based on an analysis of trade receivables, in accordance with the accounting policy stated in Notes 3.3 and 3.5.

 

The methodology for determining such losses requires significant estimates, considering several factors, among which an evaluation of receipts history, current economic trends, aging of the accounts receivable portfolio, and expectation of future losses. Although the Company believes that the assumptions used are reasonable, the actual results may be different.

 

(b)    Intangible assets arising from concession agreements and program contracts

 

Intangible assets are those arising from concession contracts, and the main costs are transferred from the Contract Asset, as described in Note 3.8.

 

Intangible assets under Concession Agreements, Service Agreements, and Program Contracts are amortized on a straight-line basis according to the period of the contract or the useful life of the asset or contract period, the lowest of them. Additional information on the accounting for intangible assets arising from concession agreements is described in Notes 3.10 and 15.

 

The recognition of the fair value of the intangible assets arising from an exchange for an asset, involving concession agreements is subject to assumptions and estimates, and the use of different assumptions may affect the accounting records. Different assumptions and future changes in the useful life of these intangible assets may have significant impacts on the result of the operations.

(c)    Pension Plan Obligations – Pension Plans

 

The Company sponsors a defined benefit plan and defined contribution plan, as described in Notes 3.20 and 22.

 

Defined pension plan obligations recognized in the statement of financial position consist of the present value of the defined benefit obligation on the reporting date less the fair value of the plan’s assets. The obligation of such benefit is calculated on an annual basis by independent actuaries, using the projected credit unit method. The present value of the defined benefit obligation is determined by discounting estimated future cash outflows, using interest rates compatible with market returns, which are denominated in the currency in which benefits will be paid and with maturity terms close to those of corresponding pension plan obligation.

 

(d)    Deferred income tax and social contribution

 

The Company recognizes and settles taxes on income based on the results of operations calculated according to Brazilian Corporation Law, taking into consideration the provisions of the tax laws. Deferred tax assets and liabilities are recorded based on the differences between the accounting balances and the tax bases of the assets and liabilities.

 

The Company regularly reviews the recoverability of deferred tax assets and recognizes a provision for impairment if it is probable that these assets will not be realized, based on the historic taxable income, on the projection of future taxable income, and on the estimated period for reversing the temporary differences. These calculations require the use of estimates and assumptions. The use of different estimates and assumptions could result in a provision for impairment of all or a significant part of the deferred tax asset. Additional information on deferred taxes is described in Notes 3.18 and 19.

 

(e)    Provisions

 

The provisions for civil, labor, environmental, and tax risks are created based on Notes 3.16 and 20. Judgments regarding future events may significantly differ from actual estimates and exceed the amounts provisioned. The provisions are revised and adjusted taking into consideration changes in the circumstances involved.

 

(f)     Unbilled revenue

 

Unbilled revenue corresponds to services rendered for which readings have not been made yet. They are recognized based on monthly estimates calculated according to average billing. Additional information on revenue and accounts receivable are described in Notes 3.4 and 10.

(d)

Judicial Bonds

 

The Company has registered warrants issued as a result of final and unappealable lawsuits for the collection of unpaid water and sewage bills from public entities. These bills are considered bad debt expenses ('PECLD') in their entirety, and the updated values of said bills, calculated according to the respective registered warrants, are not recognized due to uncertainties regarding their realization.

 

As of December 31, 2023, the Company has registered warrants issued in its favor, currently totaling R$ 3,085,265 (R$ 2,807,318 as of December 31, 2022), which, as mentioned above, are fully provisioned at their original value and do not have their respective updates recognized in the Financial Statements.

 

The reversal of the PECLD for the original bills and their update are recognized when uncertainties regarding their realization are mitigated, i.e. when the realization value becomes determinable due to the predictability of the commencement of its receipt or when negotiated with third parties.

 

The Company did not negotiate its registered warrants in the current fiscal year or in the comparative years, and there are no ongoing negotiations, as follows:

 

	Parent Company and Consolidated	Parent Company
Debtor	December 31, 2023	December 31, 2022

Other	11,918	33,804
Total	3,085,265	2,807,318

 

Additionally, the Company negotiated registered warrants for overdue bills with the municipalities of Guarulhos, Santo André, and Mauá in previous fiscal years, which are currently suspended as they serve as collateral for the fulfillment of contracts entered into with the municipalities.

(ii)

Sanitation services

 

The Company provides water supply and sewage services to the São Paulo State Government and other companies related to it, in terms and conditions deemed by Management as usual market terms and conditions, except for the settlement of credits, which may be made according to item (iii) of this Note.

 

(iii)

Reimbursement of additional retirement and pension benefits paid

 

Refers to additional retirement and pension benefits provided for in State Law 4,819/1958 ("Benefits") paid by the Company to former employees or pensioners, referred to as G0.

 

Under the GESP Agreement executed in 2001, the São Paulo State acknowledges being responsible for the charges arising from the Benefits, provided that the payment criteria established by the State Personnel Expenses Department (DDPE) be met, based on legal guidance of the Legal Counsel of the Treasury Department and the State Attorney General Office (PGE).

 

As explained in item (iv), the São Paulo State’s validation of the amounts due to the Company because of the Benefits found divergences regarding the calculation and eligibility criteria of the Benefits applied by the Company.

 

See additional information about the G0 plan in Note 22 (ii).

 

As a result of a court decision, SABESP is responsible for the payments.

(iv)

Disputed amounts

 

As of November 17, 2008, the Company and the São Paulo State signed the Third Amendment to the GESP Agreement, when the disputed and undisputed amounts were calculated. The amendment established the efforts to calculate the Disputed Amount of the Benefits. According to clause four of such instrument, the Disputed Amount consists of the difference between the Undisputed Amount and the amount actually paid by the Company as additional retirement and pension benefits provided for in Law 4,819/1958, for which the State was originally responsible for because of a court decision.

 

By entering into the Third Amendment, the State Attorney General Office (PGE) agreed to reassess the differences that gave rise to the Disputed Amount of the benefits provided for in Law 4,819/1958. At the time, this expectation was based on the willingness of the PGE to reassess the matter and the implied right of the Company to the reimbursement, including based on opinions from external legal counsel.

 

However, the recent opinions issued by the PGE received on September 4 and 22, 2009 and January 4, 2010, denied the reimbursement of the portion previously defined as Disputed Amount.

 

The third amendment also provides for the regularization of the monthly flow of benefits. While SABESP is responsible for the monthly payments, the São Paulo State shall reimburse the Company based on the criteria identical to those applied in the calculation of the Undisputed Amount. Should there be no preventive court decision, the State will directly assume the monthly payment flow of the portion deemed as undisputed.

 

Even though the negotiations with the State are still in progress, it is not possible to assure that the Company will recover the Disputed Amount in a friendly way.

 

Continuing the actions that aim to recover the credit that Management understands to be owed by the São Paulo State, related to the divergences in the reimbursement of the additional retirement and pension benefits paid by the Company, SABESP: (i) on March 24, 2010, addressed a message to the Controlling Shareholder by sending a letter resolved by the Executive Board proposing that the matter be discussed at B3’s Arbitration Chamber; (ii) in June 2010, sent to the Treasury Department a proposal of an agreement to settle said pending matters. The proposal was not accepted; (iii) on November 9, 2010, filed a lawsuit against the São Paulo State seeking full reimbursement of the amounts paid as benefits provided for in Law 4,819/1958 to settle the Disputed Amount under discussion between the Company and the São Paulo State. Despite the lawsuit, the Company will insist on reaching an agreement during the course of the lawsuit, as it believes that a reasonable agreement is better for the Company and its shareholders than waiting for the end of the lawsuit.

 

As of December 31, 2023 and 2022, the disputed amounts between SABESP and the São Paulo State, referring to additional retirement and pension benefits paid (Law 4,819/1958), totaled R$ 1,583,449 and R$ 1,482,140, respectively, for which allowances for doubtful accounts were created for the total amount.

(v)

Actuarial Liability

 

The Company recognized an actuarial liability corresponding to additional retirement and pension benefits paid to employees, retired employees, and pensioners of the G0 Plan. As of December 31, 2023 and 2022, the amounts corresponding to such actuarial liability were R$ 2,098,622 and R$ 2,002,075, respectively. For detailed information on additional retirement and pension benefits, see Note 22.

·

The first 24 installments were settled upon the transfer of 2,221,000 preferred shares issued by Companhia de Transmissão de Energia Elétrica Paulista (CTEEP), totaling R$ 87,174, based on the share closing price of March 17, 2015, which were sold on April 20, 2016; and

As of July 22, 2022, the decision regarding the lawsuit that challenged the possibility of transferring the reservoirs was published in the State Official Gazette, preventing the transfer of the reservoirs to SABESP. Accordingly, as provided for in the agreement, the São Paulo State will pay SABESP, in addition to the principal, an inflation adjustment of R$ 316,027 (restated until February 2015) in 60 installments, beginning in April 2030. The amount will be adjusted by IPCA until the initial date of the payments and, as of that date, IPCA plus simple interest of 0.5% per month will be levied on the amount of each installment.

 

In July 2022, R$ 325,561 referring to the adjustment for inflation until that date was recorded at present value.

 

As of December 31, 2023, the balance receivable was R$ 106,022 in current assets (R$ 97,075 as of December 31, 2022) and R$ 933,911 in noncurrent assets (R$ 949,589 as of December 31, 2022).

As of October 28, 2016, the Company entered into an agreement based on a Private Transaction Agreement and Other Covenants to settle the disputes fully and completely and SABESP will continue using the reservoirs.

 

As of December 31, 2023, the balance of the agreement totaled R$ 8,876 and R$ 99,279 (R$ 8,456 and R$ 95,033 as of December 31, 2022), recorded in Other liabilities, under current and noncurrent liabilities, respectively.

 

(c)    Agreements with reduced tariffs for State Entities that join the Rational Water Use Program (PURA)

 

The Company has signed agreements with government entities related to the São Paulo State Government that benefit them with a reduction of 25% in the tariff of water supply and sewage services when they are not in default. These agreements provide for the implementation of the rational water use program, which takes into consideration the reduction in water consumption.

(h)    Compensation of the Fiscal Council and Management Key Personnel

 

The compensation of the Executive Officers, members of the Audit Committee and Boards of Directors, and Fiscal Councils of the Companies controlled by the São Paulo State complies with the guidelines of the State Capital Defense Council (CODEC) and is defined at the Annual Shareholders’ Meeting, as per article 152 of Brazilian Corporation Law.

 

CODEC defines that the proposal for global and individual compensation of the statutory bodies for publicly held companies listed in B3’s Novo Mercado segment, controlled by the State, must be prepared by the Board of Directors under the Company’s Bylaws, within the scope of the Institutional Compensation Policy and submitted for approval of the Annual Shareholders’ Meeting.

 

In addition to the monthly compensation, the members of the Board of Directors, Fiscal Council, and Executive Board receive an annual reward equivalent to a monthly fee, calculated on a prorated basis referring to fees in effect in December of each year. The purpose of this reward is to define a compensation similar to the Christmas bonus paid to the Company’s registered employees, given that the relationship of Management with the Company has a statutory nature.

 

Benefits paid to Executive Officers only - meal vouchers, food vouchers, healthcare, private pension, annual rest (with the characteristic of paid leave of thirty (30) calendar days, with additional payment corresponding to one-third of the monthly fees for such rest), and FGTS.

Annual bonuses cannot exceed six times each Director’s monthly compensation or 10 % of the interest on capital paid by the Company, prevailing the shortest amount.

(*) As of December 31, 2022, the lines Concession Agreements – equity value, and Program Contracts included leases totaling R$ 54,356 and R$ 168,216 (R$ 65,012 and R$ 180,669 as of December 31, 2021), respectively.

 

As of June 30, 2020, a contract was signed for the provision of treatment services and final disposal of solid waste and collection of garbage tax in the Municipality of Diadema for 40 years. To reach the best operationalization format, treatment services and final disposal of solid waste are in the study phase and, based on the contractual provision, are subject to a partnership between SABESP and a private party, which will occur through a public call.

 

(c)    Intangible arising from concession agreements

 

The Company operates concession agreements for water supply and sewage services mostly based on agreements that define rights and obligations regarding the exploration of assets related to the provision of public services (See Note 3.10 (a)). The agreements provide for the return of the assets to the granting authority at the end of the concession period.

 

As of December 31, 2023, the Company operated in 376 municipalities in the São Paulo State, including the municipality of Olímpia (375 municipalities as of December 31, 2022). Most of these agreements are valid for 30 years, except for contracts entered into with the municipalities of Guarulhos, Mauá, Santo André, São Bernardo do Campo, São João da Boa Vista, and Tejupá, which have a 40-year term.

 

The provision of services is remunerated in the form of tariffs, regulated by ARSESP.

 

Intangible rights arising from concession agreements include:

 

(i)              Concession agreements – equity value

 

Refer to municipalities assumed until 2006, except for the municipalities assumed by the economic value through an asset valuation report prepared by independent experts. The amortization of the assets is calculated on a straight-line basis, which considers the assets’ useful life.

 

(ii)             Concession agreements – economic value

 

From 1999 to 2006, negotiations related to new concessions were conducted based on the economic and financial results of the transaction, defined in a valuation report issued by independent experts.

 

The amount defined in the respective contract, after the transaction is closed with the municipality, realized upon subscription of the Company's shares or in cash, is recorded in this line and amortized throughout the respective concession (usually 30 years). As of December 31, 2023 and 2022, there were no pending amounts related to these payments to the municipalities.

Intangible assets are amortized on a straight-line basis over the term of the contracts or the useful life of the underlying assets, whichever is shorter.

 

(iii)           Concession agreements – New Contracts

 

These refer to contracts awarded through bidding processes following the New Legal Sanitation Framework. The assets are amortized over the contracted period or the useful life of the underlying assets, whichever is shorter.

 

(iv)           Program contracts

 

Refer to the renewal of contracts previously referred to as concession agreements, whose purpose is to provide sanitation services. The amortization of the assets acquired up to the signature dates of program contracts is calculated on a straight-line basis, which considers the assets’ useful life. Assets acquired or built after the signature dates of program contracts are amortized over the contracted period (most of which for 30 years) or during the useful life of the underlying assets, whichever is shorter.

 

(v)             Program contracts – Commitments

 

Since the effectiveness of the Basic Sanitation Regulation in 2007, contracts have been renewed through program contracts. In some of these contracts, the Company undertook to financially participate in social and environmental initiatives. The assets built and the financial commitments assumed in the program contracts are recorded as intangible assets and amortized on a straight-line basis under the term of the program contract.

 

As of December 31, 2023, the amounts not yet disbursed were recorded in “Program contract commitments” under current and noncurrent liabilities, totaling R$ 21,969 and R$ 12,047 (R$ 100,188 and R$ 12,197 as of December 31, 2022), respectively.

 

(vi)           Service contracts – Municipality of São Paulo

 

As of June 23, 2010, the Company entered into an agreement with the São Paulo State and the Municipality of São Paulo to provide water supply and sewage services in the municipality of São Paulo for 30 years, extendable for another 30 years.

 

Also on June 23, 2010, the State and the Municipality signed an Agreement, with SABESP as the intervening party and ARSESP as the consenting party, whose main aspects are:

 

1. The State and the Municipality grant SABESP the right to explore sanitation services in the capital of the São Paulo State, which includes the obligation to provide such services and the right to charge the respective tariff for this service;

 

2. The state and the Municipality define ARSESP as the agency responsible for regulating (including the tariff), controlling, and monitoring the services;

3. The evaluation model used was the discounted cash flow, which considered the financial and economic sustainability of SABESP’s operations in the metropolitan region of São Paulo;

 

4. All operating costs, taxes, investments, and the opportunity cost of SABESP’s investors and creditors were considered in the cash flow analysis;

 

5. The opportunity cost of SABESP’s creditors and investors was based on the Weighted Average Cost of Capital (WACC) methodology. This cost was used as a discount rate of the cash flow, calculated at 7.75% at the time;

 

6. The agreement provides for investments corresponding to 13% of gross revenue from services provided in the Municipality of São Paulo, net of Cofins and Pasep taxes. Investment plans referring to SABESP’s execution shall be compatible with the activities and programs provided for in the State and Municipal sanitation plans, as well as in the Metropolitan sanitation plan, where applicable. The Investment Plan will be revised by the Managing Committee every four years, especially regarding investments to be made in the subsequent period.

 

7. The amount transferred to the Municipal Fund for Environmental Sanitation and Infrastructure (FMSAI) to be invested in sanitation services in the municipality must be recovered through tariff charges, as agreed upon in the contract. This amount accounts for 7.5% of the total revenue from services provided in the Municipality of São Paulo, net of Cofins and Pasep, and delinquency is retained in the municipalities until it is settled. Amounts transferred to FMSAI are recorded in profit or loss as operational cost;

 

8. The agreement provides for the remuneration of net assets in operation, preferably calculated through equity valuation or carrying amount adjusted for inflation, as defined by ARSESP. In addition, it provides for the remuneration of investments to be made by SABESP, so that there is no residual value at the end of the Agreement.

 

As of December 16, 2016, as a result of the 1st Four-Year Review, the 1st amendment to the contract was signed, updating the exhibits related to the Coverage Targets Plan and service quality, the Investment Plan, and the Investment Compatibility Strategy.

 

Regarding the recovery of the amount transferred to the Municipal Fund for Environmental Sanitation and Infrastructure through tariff charges, mentioned in item 7 above, in April 2013, ARSESP issued Resolution 413, postponing the application of Resolution 407 and suspending, until the conclusion of the tariff review process, the transfer of services corresponding to municipal charges to consumers, as established in Resolution 407. The postponement of Resolution 407 was due to a request by the São Paulo State to analyze, among other things, methods to reduce the impact on consumers.

As of April 18, 2014, ARSESP published Resolution 484 with the final result of SABESP’s Tariff Revision. However, both the São Paulo Municipal Government, through Official Letter 1,309/2014-SGM/GAB, and the São Paulo State, through a petition filed by the São Paulo State Office, through Official Letter ATG/Official Letter 092/2014-CC, requested a postponement of the effects of ARSESP Resolution 413, published in the São Paulo State Official Gazette on March 20, 2013, until the conclusion of the revision of the Agreement entered into between the São Paulo Municipal Government, the São Paulo State, and SABESP.

 

As of May 9, 2018, ARSESP announced the final result of the Second Ordinary Tariff Revision and, as of this revision cycle, ARSESP has been transferring the tariffs up to 4% of municipal revenue, which is transferred from SABESP to the Municipal Fund for Environmental Sanitation and Infrastructure legally created. Under the Second Ordinary Tariff Revision, concluded in May 2018, the only contract providing for that transfer and meeting the requirements of ARSESP was the one executed with the municipality of São Paulo. Accordingly, 4% of the funds transferred to the Municipal Fund for Environmental Sanitation and Infrastructure of São Paulo were transferred to the tariffs of the tariff cycle ended in April 2021.

 

The Municipal Government of São Paulo, the São Paulo State Government, ARSESP, and the Company have not reached an agreement to define the percentage of the Municipal Fund for Environmental Sanitation and Infrastructure transfer to the tariffs charged by the Company in the Municipality of São Paulo, which led to the filing of a lawsuit by the municipality claiming the percentage provided for in the contract between the parties. As requested by the municipality, the lawsuit is currently suspended.

 

At the time of execution of the agreement, the Municipality of São Paulo and the Company did not agree to settle the pending financial issues existing, related to the rendering of water supply and sewage services to the properties of the Municipality, and for that reason, the Company filed lawsuits for collection of the aforementioned amounts, which remain in progress and are recorded under allowance for doubtful accounts.

 

As of December 31, 2023 and 2022, the agreement entered into with the Municipality of São Paulo accounted for 44.95% and 45.14%, respectively, of the Company’s sanitation revenue, which ensures legal and property security to SABESP.

 

(d)   Public-Private Partnership - PPP

 

SABESP carries out operations related to the PPPs mentioned below. These operations and their respective guarantees are supported by agreements executed according to Law 11,079/2004.

Alto Tietê Production System (PPP SPAT)

 

In June 2008, SABESP and the special purpose entity CAB-Sistema Produtor Alto Tietê S/A (currently SPAT Saneamento S/A), formed by Galvão Engenharia S.A. and Companhia Águas do Brasil – Cab Ambiental, signed the contracts of the Public-Private Partnership of the Alto Tietê production system, to expand the capacity of the Taiaçupeba Water Treatment Station, from 10 thousand to 15 thousand litters per second, valid for 15 years from the commencement of the works.

 

The works started in February 2009 and the SPAT PPP started operating in October 2011.

 

SABESP monthly transfers funds from tariffs collected for services provided to the SPE CAB Sistema Produtor Alto Tietê S/A, totaling R$ 14,740, corresponding to monthly remuneration. This amount is annually adjusted by the IPC – FIPE and is monthly recorded in a restricted account, as established in the contracts. If SABESP complies with its monthly obligations with the SPE, the funds from the restricted account will be released.

 

The guarantee has been effective since the beginning of the operation and will be valid until the end, termination, intervention, annulment, or caducity of the Administrative Concession, or other events of extinction provided for in the Concession Agreement or the legislation applicable to administrative concessions, including in the event of bankruptcy or dissolution of the SPE.

 

São Lourenço Production System (PPP SPSL)

 

In August 2013, the Company and the special purpose entity Sistema Produtor São Lourenço S/A, formed by Construções e Comércio Camargo Corrêa S/A and Construtora Andrade Gutierrez S/A, signed the Public-Private Partnership contracts of the São Lourenço Production System, valid for 25 years from the commencement of the works.

 

In May 2018, the control of SPE Sistema Produtor São Lourenço S/A was transferred to CGGC Construtora do Brasil Ltda, previously formed by Construções e Comércio Camargo Corrêa S/A and Construtora Andrade Gutierrez S/A.

 

The objective of the contract is (i) the construction of a water production system, mainly consisting of a water pipeline connecting Ibiúna to Barueri, a water collection station in Ibiúna, a water treatment station in Vargem Grande Paulista and water reservoirs; and (ii) for the operation of the system to dewater, dry and provide final disposal of sludge, maintenance, and works of the São Lourenço Production System project.

 

The works started in April 2014 and the São Lourenço Production System (SPSL) PPP started operating on July 10, 2018.

Since the beginning of operations, the Company monthly transfers funds from tariffs collected for services provided to the SPE Sistema Produtor São Lourenço S/A, in the amount of R$ 42,904, corresponding to monthly remuneration plus any interests and charges. This amount is annually adjusted by the IPC – FIPE and is monthly recorded in a restricted account, as established in the contracts. If the Company complies with its monthly obligations with the SPE, the funds from the restricted account will be released.

 

The guarantee has become effective since the start of operations of the system, with acceptance by SABESP, and will be valid until one of the following events occurs, whichever occurs first (i) the original payment date of the last installment of interest/amortization of the main financing that the SPE may contract for the performance of the works; (ii) end, termination, intervention, annulment or caducity of the Administrative Concession, or other events of extinction provided for in the Concession Agreement or the legislation applicable to administrative concessions, including in the event of bankruptcy or dissolution of the SPE.

 

Intangible assets were accrued based on the physical performance of the works, with the Public-Private Partnership accounts being the corresponding entries in liabilities.

 

The discount rates used in the agreements of the Public-Private Partnerships Alto Tietê and São Lourenço are 8.20% and 14.85% p.a., respectively, for the calculation of the present value adjustment.

 

The amounts recorded in intangible assets are as follows:

 

	Parent Company and Consolidated	Parent Company
	December 31, 2023	December 31, 2022

Expenses of short-term leases with low value	(26,776)	(25,365)
Reduction of profit for the year	(198,313)	(202,966)

 

 

(g)    Performance Agreements

 

SABESP has performance agreements for the construction of assets, in which the contractor is paid for the delivery of results, not only for the execution of the construction works.

 

The performance agreements have three phases: (i) implementation of the scope - construction of the asset; (ii) calculation of the performance of the asset built; and (iii) payment of fixed installments.

 

SABESP monitors the performance of the agreement and recognizes the assets when future economic benefits are generated for the Company so that costs can be reliably measured. The performance value is part of the asset’s cost, as it has better performance and, consequently, generates additional future economic benefits for the Company.

 

The limit to be paid to the supplier corresponds to 120% of the base value of the agreement. In most agreements, when the minimum performance percentage is not reached, the amount to be paid to the supplier will be the cost of the materials used in the construction of the assets only.

 

As of December 31, 2023, the accounting balances of the agreements in force recorded in contract asset and intangible assets were R$ 183,876 and R$ 2,191,361 (R$ 138,550 and R$ 2,126,106 as of December 31, 2022), respectively.

(b)    Lawsuits deemed as contingent liabilities

 

The Company is a party to lawsuits and administrative proceedings relating to environmental, tax, civil, and labor claims, which are assessed as contingent liabilities in the financial statements, since it either does not expect outflows to be required or the amount of the obligations cannot be reliably measured. Contingent liabilities, net of deposits, are represented as follows:

 

	Parent Company and Consolidated	Parent Company
	December 31, 2023	December 31, 2022
Customer claims (i)	158,584	200,966
Supplier claims (ii)	968,752	1,147,606
Other civil claims (iii)	695,097	1,146,048
Tax claims (iv)	1,067,350	1,869,583
Labor claims (v)	3,093,735	1,471,423
Environmental claims (vi)	4,158,504	3,302,843
Total	10,142,022	9,138,469

 

 

(c)    Explanation of the nature of main classes of lawsuits

 

(i)

Customer claims

 

Refer mainly to lawsuits from customers claiming that their tariffs should be equal to those of other consumer categories, lawsuits for reduction of sewage tariff due to system losses, consequently requiring the refund of amounts charged by the Company, and lawsuits for reduction of tariff for being eligible to the Social Welfare Entity category.

 

(ii)

Supplier claims

 

Include lawsuits filed by some suppliers alleging underpayment of monetary adjustments and economic and financial imbalance of the agreements, and are in progress at different courts.

 

(iii)

Other civil claims

 

Refer mainly to indemnities for property damage, pain and suffering, and loss of profits allegedly caused to third parties, such as vehicle accidents, claims, challenges on the methodology to collect tariffs, among others, filed at different court levels.

(iv)

Tax claims

 

Tax claims refer mainly to tax collections and fines in general challenged due to disagreements regarding notification or differences in the interpretation of legislation by the Company's Management.

 

The Municipality of São Paulo, through Law 13,476/2022, revoked the exemption of the service tax held by the Company until then and issued tax deficiency notices related to sewage services and ancillary activities, in the adjusted amount of R$ 1,044,035 (R$ 957,199 as of December 31, 2022), which were subject to three tax foreclosures. SABESP filed for a writ of mandamus against the revocation, which was denied. It also filed for provisional measures and actions for annulment, aiming at the suspension of enforceability of the credits and annulment of the tax deficiency notices, as it understands that notwithstanding the revocation of the exemption, sewage activities and ancillary activities are not on the list of activities that may be taxed by the Municipality. Activities related to sewage services reached a favorable outcome, and are awaiting the processing of appeals at a higher level. Regarding the middle activities, the decision was partially favorable and SABESP’s appeal was denied. SABESP filed a special appeal requesting a suspensive effect, which was not admitted at the origin. An interlocutory appeal was filed with the Superior Court of Justice, whose decision was unfavorable to the Company. The main lawsuit remains suspended.

 

(v)

Labor claims

 

The Company is a party to several labor lawsuits, involving issues such as overtime, shift schedule, health hazard premium, hazardous duty premium, prior notice, change of function, salary equalization, service outsourcing, and others, which are at various court levels.

 

(vi)

Environmental claims

 

These refer to several administrative proceedings and lawsuits filed by government entities, including Companhia Ambiental do Estado de São Paulo (CETESB) and the Public Prosecution Office of the São Paulo State, which aim at certain obligations to do and not to do, with the provision of fines for non-compliance, and imposition of compensation for environmental damages allegedly caused by the Company.

 

The main objects in which the Company is involved are: a) blame SABESP for discharging or releasing sewage without proper treatment; b) invest in the water and sewage treatment system of the municipality, under penalty of paying a fine; c) pay compensation for environmental damages; amongst others.

 

(d)    Other concession-related claims

 

The Company is a party to concessions-related claims, in which it challenges compensatory issues for the resumption of sanitation services by some municipalities or the right to continue operating such services.

The amount recognized in noncurrent assets as indemnities receivable, referring to the municipalities of Cajobi, Macatuba, Álvares Florence, Embaúba, Araçoiaba da Serra, and Itapira totaled R$ 27,539 as of December 31, 2023 and 2022; it also recorded the full amount of estimated losses. None of the above-mentioned municipalities are operated by the Company. When a final judgment grants a municipality the right to repossess and operate sanitation services, Brazilian legislation provides for the payment of compensation for the investments made by the Company.

 

(e)    Environmental claims with executed agreements

 

The Company entered into a court agreement in 2023, without the need for environmental compensation.

 

(f)     Guarantee insurance

 

As of May 25, 2023, the Company executed an agreement effective for one year for the issue of policies under several types of guarantee insurance. The limit that can be used is R$ 600 million. The guarantee insurance for escrow deposit is used in legal claims, where instead of immediately disbursing cash, the Company uses the guarantee provided by the insurance until the end of these proceedings, limited to up to five years. As of December 31, 2023, R$ 364.1 million was available for use.

Benefits granted are paid after the event, free of choice, and are sponsored by the contributions of SABESP and the employees. In 2023, the Company contributed 9.18%, on average, of gross payroll, totaling R$ 313,034 (8.80% in 2022, totaling R$ 272,460).

(ii)

Provision for profit sharing

 

Based on an agreement with the labor unions, the Profit Sharing Program corresponds to up to one month’s salary for each employee, subject to the achievement of the goals established, from January to December, and should be paid in the subsequent year.

 

(iii)

Incentivized Dismissal Program - PDI

 

In June 2023, the Company implemented the Incentivized Dismissal Program (PDI or Program) to pacifically reduce the workforce and provide gains in efficiency, increase of competitiveness, and optimization of costs.

 

The deadline for registrations in the Program was from June 01 to 30, 2023, and the employment terminations started on July 01, 2023 and will end on June 30, 2024. The PDI received registrations from 1,862 employees.

 

For all Program participants, compliance with the clauses contained in the Collective Bargaining Agreement effective on the date of termination is guaranteed, and the following compensation incentives will be granted:

 

a.

half of the indemnified advance notice, proportional to the service time at SABESP, equivalent to the percentage of the FGTS balance for termination purposes on the date of termination (according to the table below);

 

b.

compensation incentive proportional to the service time at SABESP based on the base salary + function bonus, for each complete year of work (according to the table below); and

 

c.

health plan: starting from the subsequent month of termination, the health plan will be the responsibility of the policyholder and SABESP will reimburse the monthly fee up to an individual amount of R$ 1,878.30/month for the policyholder and his/her spouse for 24 consecutive and uninterrupted months. If the policyholder chooses a health plan with a monthly fee lower than the reimbursable amount, he/she will not be entitled to any difference, thus not generating any credit or balance to be offset against future installments over the course of the 24 consecutive and uninterrupted months.

 

Service time at SABESP (years)	% of the FGTS balance	% of the compensation for each complete year of work
> 15	20%	20%
11 - 15	12.5%	12.5%
6 - 10	5%	5%
0 - 5	2.5%	2.5%

 

As of December 31, 2023, R$ 359,943 was recorded due to the provision for employee compensation incentives, of which R$ 290,202 in current liabilities and R$ 66,741 in noncurrent liabilities under “Labor Obligations”.

The balance payable of interest on capital as of December 31, 2023, of R$ 837,391 (R$ 741,725 in 2022), refers to the amount of R$ 836,839 (R$ 741,301 in 2022) declared in 2023, net of withholding income tax, and R$ 552 declared in prior years (R$ 424 in 2022).

The Company may not create the legal reserve in the year in which the balance of this reserve, plus the amount of the capital reserves, exceeds 30% of the share capital. The purpose of the legal reserve is to ensure the integrity of the share capital. It can only be used to offset losses or increase capital, not to pay dividends.

 

(d)    Investment reserve

 

Profit reserve - investment reserve: specifically created from the portion corresponding to the own resources that will be allocated to the expansion of the water supply and sewage systems, based on a capital budget approved by Management.

I-

its balance, together with the balance of the other profit reserves, except for the reserves for contingency and unrealized profit, may not exceed the share capital; and

II-

the purpose of the reserve is to ensure the investment plan and its balance may be used:

a) in the absorption of losses, whenever necessary;

b) in the distribution of dividends, at any time;

c) in transactions for the redemption, refund, or purchase of shares, authorized by law; and

31st issue debentures

 

As of March 05, 2024, the Company raised R$ 2.94 billion from the 31st issue of simple, unsecured debentures, not convertible into shares, in three series, for public distribution, under the automatic distribution procedure aimed at professional investors, according to CVM Resolution 160, with the following characteristics:

 

	Value	Rate	Maturity
Series 1	507,000	CDI + 0.49% p.a.	2029
Series 2	1,734,467	CDI + 1.10% p.a.	2031
Series 3	699,011	CDI + 1.31% p.a.	2034
Total	2,940,478

 

·

The covenants agreed upon for the 31st issue are:

Calculated every quarter, when disclosing the quarterly information or annual financial statements:

- Net debt/adjusted EBITDA lower than or equal to 3.50;

- Adjusted EBITDA/financial expenses equal to or higher than 1.5;

Failure to comply with the financial indices above for at least two consecutive quarters, or for two non-consecutive quarters within twelve months (in which case the 30-day cure period does not apply), constitutes a default event that may lead to the early maturity of the Debentures.- Disposal of operating assets, termination of licenses, loss of concession, or loss of the Company’s ability to execute and operate public sanitation services in areas of the São Paulo State which, individually or jointly during the term of the agreement, lead to a reduction of the Company’s net sales and/or service revenue of more than twenty- five percent (25%). The above limit will be calculated every quarter, taking into consideration the Company’s net operating income during the twelve (12) months before the end of each quarter and using the financial information disclosed by the Company. Failure to comply with the limit above constitutes a default event that may lead to the early maturity of the Debentures.

The contract has a cross acceleration clause, i.e. the early maturity of any of the Company’s debts, in an individual or aggregate amount equal to or higher than R$ 198 million, adjusted by the IPCA inflation index as of the issue date, constitutes a default event and may result in the early maturity of the Debentures.

The proceeds from the issue will be used to refinance financial commitments falling due in 2024 and to recompose and reinforce the cash position. The Debentures are characterized as “ESG bonds for the use of sustainable and blue resources”, based on the Company’s commitment to allocate the equivalent amount in projects described in the Sustainable Finance Framework.

Agreement with AAPS - Association of Retirees and Pensioners of SABESP

 

The health plans for retirees, former employees, pensioners, and dependents (Digna Mais 1, 2, 3, 4, and 5) comply with Federal Law 9,656/98.

Under articles 30 and 31 of said Law, as well as Regulatory Resolution 279 and subsequent regulations by the National Health Agency, beneficiaries who join these plans are responsible for full cost coverage (monthly premiums and any deficits). Through an amendment to the Adhesion Agreement maintained with VIVEST, SABESP acts as a guarantor to the Health Operator.

Until December 31, 2023, in this guarantor role, the Company recognized debit notes received to cover deficits totaling R$ 47.5 million. The deficits in these portfolios result from a structural imbalance between the fee tables and the profile of the population, leading to expenses exceeding revenues. After this payment, SABESP initiated the collection process from the beneficiaries, resulting in accounts receivable of equal value and the recognition of a loss due to bad debt expenses for the entire amount.

This collection process triggered negotiations with the Association of Retirees and Pensioners of SABESP (AAPS), which resulted in the signing of a judicial agreement on January 31, 2024 (ratified by the judiciary on February 27, 2024), which includes:

a)

Settlement of each beneficiary's deficit by SABESP;

b)

Migration of beneficiaries to VIVEST's Essência Health Plans or other market plans derived from the Digna Mais plans;

c)

Withdrawal, by AAPS, of a Lawsuit for Compliance with Ruling 0056668-84.2020.8.26.0100, which sought to merge active and retired individuals into a single plan, potentially leading to a post-employment liability and an expected loss as of December 31, 2022, of R$ 303.9 million.

As part of the negotiation, VIVEST indicated a potential imbalance in the Essência plans with the migration of retirees, former employees, pensioners, and dependents, resulting from adverse risk selection. Given this scenario, SABESP, to enable the settlement of the Digna Mais plans, entered into a new amendment to the Adhesion Agreement with VIVEST, which includes:

a)

VIVEST will allow migrations to the Essência plans, assuming the portfolio risk;

b)

SABESP will make a one-time contribution to VIVEST for each person who migrates to one of its Essência plans, subject to approval by the judiciary (as occurred on February 27, 2024), with contributions as follows:

b.1) R$ 10.0 million, paid in a lump sum in February 2024, based on the 2,909 beneficiaries migrated from Digna Mais plans to Essência plans;

b.2) Amount corresponding to the number of beneficiaries who join Essência plans, capped at R$ 160.0 million (1,754 beneficiaries enrolled in Digna Mais plans as of March 2023), from January 2024 onwards.

This monthly per capita amount will be paid from the entry date of each beneficiary or from January 2024, whichever occurs later, until December 2028, with financial support to mitigate the impacts of annual cost variations to be applied from January 2025 to January 2029 to Essência plans. After the effective payment of all installments, including the last one for December 2028, the Company will be exempt from any payments to VIVEST. The above amounts will be annually adjusted, with a reference date in January, according to the annual adjustment index of the Essência plans.

Until December 31, 2023, before the agreement, there were migrations of 131 beneficiaries, and from January 01 to March 14, 2024, the migrations came to 766 beneficiaries as a result of the agreement, a known impact of R$ 90.2 million in the provision to be recorded in the 1st quarter of 2024.

4.

ASSESSMENT OF THE EFFECTIVENESS OF INTERNAL CONTROL SYSTEMS

The methodology adopted by SABESP to analyze the internal controls complies with the Internal Control - Integrated Framework, defined by The Committee of Sponsoring Organizations of the Treadway Commission (COSO) and the Sarbanes-Oxley Act.

SABESP’s Management is liable for designing and implementing internal control policies, processes, and practices to enable the safeguarding of assets, the appropriate recognition of liabilities, the adhesion to the rules, integrity and accuracy of information.

The Internal Audit is liable for assessing the level of service or observance by all SABESP’s areas, internal control procedures, and practices and if they have been effectively applied.

The Audit Committee supervised the activities related to the implementation and evaluation of internal controls through presentations by the areas responsible for controls and the findings reported by the Internal and Independent Auditors.

5.

ASSESSMENT OF THE EFFECTIVENESS OF INTERNAL AND INDEPENDENT AUDITS

The Committee also maintains a regular channel of communication with internal and independent auditors, allowing a broad discussion on their work results, the accounting aspects, and relevant internal controls, and as a result, it assesses as fully satisfactory the volume and the quality of the information provided by these professionals, who support their opinion on the adequacy and integrity of internal controls systems and the financial statements.

The Committee monitored the activities carried out by Internal and Independent Auditors, whether through periodic meetings, or review of reports issued. Accordingly, the Committee positively assesses the coverage and the quality of works performed by Internal and Independent Auditors, concerning the financial statements for the fiscal year ended December 31, 2023.

During the performance of works, the Committee did not identify any situation that could affect the objectivity and independence of Grant Thornton and BDO RCS Auditores Independentes concerning SABESP. Therefore, according to the Audit Committee’s Charter, the Committee informs the Board of Directors that it is not aware of any type of relationship between Grant Thornton and BDO RCS regarding SABESP that may have affected its independence in performing the independent audit of the financial statements for the fiscal year ended December 31, 2023.

Additionally, the Committee did not identify any significant divergence between Sabesp’s Management, BDO RCS, and the Audit Committee regarding Sabesp’s 2023 Financial Statements.
