Impacts from the exchange variation

Exchange variation expenses on borrowings and financing fell by R$ 279.9 million, due to the lower appreciation of the U.S. dollar and the depreciation of the Japanese Yen against the Brazilian real in 3Q22, compared to the appreciation reported in 3Q21 for both currencies, as shown in the table below:

(*) Number of shares = 683,509,869

The Adjusted EBITDA margin was 35.7% in 3Q22, compared to 34.7% reported in 3Q21 (32.4% in the last 12 months).

Excluding the effects of revenue and construction costs, the adjusted EBITDA margin reached 45.4% in 3Q22, compared to 44.4% in 3Q21 (40.6% in the last 12 months).

The Company recorded a net income of R$ 1,081.1 million in 3Q22, compared to R$ 468.6 million in 3Q21.

The gross operating revenue from sanitation services, which excludes construction revenue, totaled R$ 5,012.4 million in 3Q22, an increase of R$ 727.5 million (+17.0%) over the R$ 4,284.9 million recorded in 3Q21.

The main factors that led to the increase were:

Construction revenue increased by R$ 164.1 million (+13.8%), due to higher investments made.

The following tables show the water and sewage billed volume, on a quarter-over-quarter and year-over-year basis, per customer category and region.

(1) Unaudited by external auditors

(2) Including coastal and interior regions

(3) Wholesale includes volumes of reuse water and non-domestic sewage

Costs, administrative and selling expenses, and construction costs increased by R$ 537.7 million in 3Q22 (+13.7%). Excluding construction costs, the increase was R$ 377.3 million (+13.6%).

Costs, administrative and selling expenses, and construction costs as a percentage of net revenue were 74.7% in 3Q22, compared to 76.3% in 3Q21.

Salaries, payroll charges and benefits, and Pension plan obligations

The R$ 83.5 million increase (+12.3%) recorded in 3Q22 was mainly due to:

General supplies

Increase of R$ 28.5 million (+ 35.9%), mainly due to the:

Treatment supplies

Increase of R$ 67.8 million (+82.6%), mainly due to higher product prices and higher use of algaecides, coagulants, and disinfectants in several Water Treatment Stations to maintain the quality of raw water.

The prices of several materials used in the treatment process of water and sewage, such as aluminum sulfate, ferric chloride, and aluminum polychloride, were impacted by the international market.

Services

Service expenses totaled R$ 635.3 million, an increase of R$ 113.3 million (+21.7%) over the R$ 522.0 million recorded in 3Q21. The main increases were:

Electricity

Electricity expenses totaled R$ 359.3 million in 3Q22, an increase of R$ 15.7 million (+4.2%) over the R$ 375.0 million recorded in 3Q21. Of the total, the Free Market Tariffs (ACL) accounted for 54.1% of total expenses in 3Q22 (53.2% in 3Q21) while the Regulated Market Tariffs (ACR) accounted for 45.9% (46.8% in 3Q21).

The main factors that contributed to this variation were:

Year-over-year, electricity tariffs were impacted, among others, by (i) the red tariff flag in 3Q21; and (ii) the lower tax burden on electricity bills in 3Q22, as a consequence of Supplementary Law 194/2022.

General expenses

Increase of R$ 34.1 million (+10.4%), totaling R$ 361.5 million in 3Q22, compared to the R$ 327.4 million recorded in 3Q21, mainly from the (i) higher provision for transfer to the Municipal Funds for Environmental Sanitation and Infrastructure, of R$ 27.1 million; and (ii) higher lawsuit expenses in 3Q22, of R$ 7.3 million.

Expenses with municipal transfers totaled R$ 193.0 million in 3Q22, compared to the R$ 165.9 million reported in 3Q21 (+16.3%), mainly due to higher operating revenue reported in 3Q22.

Depreciation and amortization

The R$ 48.8 million increase (+8.6%) was mainly due to the beginning of operations of intangible assets, totaling R$ 4.8 billion.

Allowance for doubtful accounts

Increase of R$ 17.2 million, from R$ 118.6 million in 3Q21 to R$ 135.8 million in 3Q22, due to higher provisioning arising from the increase in default in 3Q22.

Financial expenses, net of revenue

The main impacts resulted from:

Monetary and exchange variations, net

The effect of net monetary and exchange variations in 3Q22 was R$ 661.3 million, lower than the figure reported in 3Q21, especially due to:

The R$ 319.3 million increase in 3Q22 was mainly due to:

⁽¹⁾ Total connections, active and inactive, in thousand units at the end of the period. Excludes Mauá in 3Q21.

⁽²⁾ In million inhabitants, at the end of the period. Does not include wholesale.

Covenants

The table below shows the most restrictive clauses in 3Q22:

As of September 30, 2022, the Company had met the requirements of its borrowings and financing agreements.

Investments totaled R$ 1,430.3 million in 3Q22, presented as additions in the notes to the quarterly information under Contract Asset, Intangible Assets, and Property, Plant and Equipment, of R$ 1,388.4 million, R$ 24.2 million, and R$ 17.7 million, respectively. Cash disbursed in 3Q22 referring to investments, including from previous periods, totaled R$ 1,030.7 million.

The table below shows investments in 3Q22, broken down by water, sewage, and region:

Companhia de Saneamento Básico do Estado de São Paulo (SABESP or Company) is a mixed-capital company headquartered in the municipality São Paulo, at Rua Costa Carvalho, 300, CEP 05429-900, controlled by the São Paulo State. The Company is engaged in the provision of basic and environmental sanitation services in the São Paulo State, as well as supplies treated water and sewage services on a wholesale basis.

In addition to providing basic sanitation services in the São Paulo State, SABESP may perform activities in other states and countries and can operate in drainage, urban cleaning, solid waste handling and energy markets. SABESP aims to be a world reference in the provision of sanitation services, in a sustainable, competitive, and innovative manner, with a focus on customers.

As of September 30, 2022, the Company operated water and sewage services in 375 municipalities of the São Paulo State, 351 of which have already signed contracts, according to Law 11,445/2007. Most of these municipalities’ operations are based on 30-year concession, program, and service contracts, except for the municipalities of Guarulhos, Mauá, Santo André, São Bernardo do Campo, São João da Boa Vista, and Tejupá, which have 40-year term contracts.

The table below shows a summary of the contractual situation of the municipalities served:

The Company's shares have been listed on the Novo Mercado segment of B3 under ticker SBSP3 since April 2002 and on the New York Stock Exchange (NYSE) as Level III American Depositary Receipts (“ADRs”), under ticker SBS, since May 2002.

Since 2008, the Company has been setting up partnerships with other companies, which resulted in the following companies: Sesamm, Águas de Andradina, Saneaqua Mairinque, Aquapolo Ambiental, Águas de Castilho, Attend Ambiental, and Paulista Geradora de Energia. Although SABESP has no majority interest in the capital stock of these companies, the shareholders’ agreements provide for the power of veto and casting votes on certain issues jointly with associates, indicating the shared control in the management of these investees, except for Saneaqua Mairinque, which, as of August 2020, no longer has a shared control.

Economic instability worsened by COVID-19

Regarding the effects of COVID-19, we emphasize the migration, in 2020, of the billed volume of the public, commercial, and industrial categories that have average tariffs higher than the tariff charged from the residential category. However, since 2021, the billed volume has been resuming for these categories with consequent recovery in the average tariff price.

Expenses with allowance for doubtful accounts are still rising over the same period in 2021, due to the higher delinquency in 2022.

New Legal Sanitation Framework

On July 15, 2020, Federal Law 14,026/2020, known as New Legal Framework for Basic Sanitation, was sanctioned. The new law expands competition in the sector by extinguishing program contracts, encourages the region-wise provision of services to promote economies of scale, and provides for strengthening the service regulation.

Additionally, the New Legal Framework imposes performance goals to reach 99% of the population served with drinking water and 90% with sewage collection and treatment by December 31, 2033, encouraging operators to increase efficiency. The new Law also granted the National Water Agency (ANA) with power to edit reference rules to regulate sanitation services, aiming to standardize the operation of the regulatory agencies and minimize regulatory uncertainties, thus creating a more stable and attractive environment for investments in the sector.

On May 31, 2021, Federal Decree 10,710 was published, regulating article 10-B of Law 11,445/2007, establishing the methodology for proving the economic and financial capacity of public providers of drinking water supply and sewage services, to make it possible the compliance with the universalization goals by 2033. Said Decree determined economic and financial evaluation metrics on service providers to prove their ability to make investments within the intended deadlines and several conditions for current contracts to be considered regular. Any adjustments to them should be made by March 31, 2022, in line with paragraph 1 of article 11-B of the New Legal Framework.

According to the aforementioned Decree, as of December 30, 2021, the Company presented a requirement to the São Paulo State Utility Services Regulatory Agency (ARESESP) containing documents that prove its capacity to maintain the provision of services in the operated area by meeting the goals of universal water and sewage collection and treatment by 2033, defined by the New Legal Framework, attested and certified by the independent auditors. As of March 28, 2022, ARSESP recognized the Company’s economic-financial capacity, under the applicable legislation.

In this new context, the Company understands that it is important to highlight that: i) it has 366 regular contracts that have already been adapted to the provisions of the New Legal Framework, which ensure 99.5% of revenue; ii) it has access to public capital and the private capital market, due to its sound reputation, favoring the maintenance and/or expansion of its operating base and compliance with the universalization of services within the deadline established by the new law; and iii) it has high governance level.

Management expects that the financial funds raised with the gradual recovery of the economic activities, improved water security from the works carried out, 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 quarterly information was approved by the Board of Directors on November 10, 2022.

Presentation of the Quarterly Information

The quarterly information as of September 30, 2022, was prepared based on the provisions of CPC 21 (R1) – Interim Financial Information and the international standard IAS 34 – Interim Financial Reporting, issued by the International Accounting Standards Board (IASB), applicable to the preparation of the Quarterly Information Form – ITR, and is fairly presented consistent with the rules issued by the Brazilian Securities and Exchange Commission (CVM).

All material information related to the quarterly information, and this information alone, is being disclosed and corresponds to the information used by the Company’s Management in its administration.

The amounts disclosed in the Notes to the quarterly information are in thousands of Brazilian reais, unless otherwise stated.

The accounting policies used in the preparation of the quarterly information as of September 30, 2022, are consistent with those used to prepare the Annual Financial Statements for the year ended December 31, 2021, disclosed in Note 3 of such financial statements.

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 used derivative instruments in any of the reported periods.

Exchange risk

Currency 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 the U.S. dollar 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$ 2,648,470 as of September 30, 2022 (R$ 3,321,489 as of December 31, 2021), is indexed to the U.S. dollar and Yen. The exposure to exchange risk is as follows:

The 20.6% decrease in the balance of the foreign currency-denominated debt from September 30, 2022 compared to December 31, 2021 was mainly impacted by the depreciations of the US dollar and Yen against the Brazilian real. The table below shows the prices and exchange variations in the period:

The exchange variation in borrowings and financing fell by R$ 554,575 from January to September 2022 (R$ 305,357 from January to September 2021), which accounted for 8.6% of the reduction in borrowings and financing. See Note 16 (ii). As of September 30, 2022, if the Brazilian real had depreciated or appreciated by 10 percentage points, in addition to the impacts already mentioned above, against the US dollar and Yen with all other variables held constant, the effects on results before taxes on the nine-month period ended September 30, 2022 would have been R$ 264,847 (R$ 326,427 for the nine-month period ended September 30, 2021), lower or higher.

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

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 variable interest rates:

(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 September 30, 2022, 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 nine-month period ended September 30, 2022 would have been R$ 167,090 (R$ 150,786 for the nine-month period ended September 30, 2021), lower or higher, mainly as a result of lower or higher interest expense on floating rate borrowings and financing.

Credit risk is related to cash and cash equivalents, financial investments, as well as credit exposures of 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 September 30, 2022, is the carrying amount of instruments classified as cash and cash equivalents, financial investments, restricted cash, trade receivables, and accounts receivable from related parties on the reporting date of this quarterly information. See Notes 6, 7, 8, 9, and 10.

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:

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