Water supply and sewage services in the Municipality of Olímpia

On October 11, 2023, the Company signed a Concession Agreement to provide public water supply and sanitation services to the Municipality of Olímpia, after establishing SPE SABESP Olímpia S/A. On this date, the SPE started to assist the current service provider DAEMO (Department of Water and Sewage of the Municipality of Olímpia) during a period of 60 days, after which the entire operation will be transferred and carried out by SPE SABESP Olímpia, with the start of the Concession term.

There was no impact in results in 3Q23.

03.

Revenue from sanitation services

Increase of R$ 527.0 million (+10.5%), impacted by: (i) a 9.6% tariff adjustment implemented since May 2023; (ii) a 3.5% increase in total billed volume; and (iii) a higher average tariff due to the increase in ranges with higher consumption in the residential category.

04.

Impacts from the exchange variation

In 3Q23, there was a negative exchange variation, with a YoY impact of R$ 77.2 million, due to the appreciation of the U.S. Dollar and the Yen in 3Q23, compared to the appreciation of the U.S. Dollar and the depreciation of the Yen in 3Q22, as shown below:

· R$ 15.1 million in health care expenses, due to higher use of services and increased average hospital costs.

The R$ 683.9 million increase (+31.0%) in 9M23, was mainly due to:

Earnings
Results 3Q23

Page 7

GENERAL SUPPLIES

Decrease of R$ 11.2 million (-10.4%), spread across various, the most significant of which was the R$ 3.0 million decrease with fuels and lubricants.

TREATMENT SUPPLIES

Decrease of R$ 36.7 million (-24.5%), due to: (i) the decrease in some product prices, some of which were impacted by the international market, such as aluminum polychloride; and (ii) the lower use of algaecides, coagulants, and disinfectants in several water treatment plants to maintain the quality of raw water.

Decrease of R$ 23.0 million (-5.2%) in 9M23, mainly impacted by the volatility in the international prices and the product utilization mix aligned with the strategy of achieving the best cost/benefit. Furthermore, due to the greater availability of water, it was possible to use more water from reservoirs that have lower treatment costs.

SERVICES

Service expenses totaled R$ 724.5 million, an increase of R$ 89.2 million (+14.0%) over the R$ 635.3 million recorded in 3Q22. The main increases were:

· R$ 8.2 million with surveillance; and
· R$ 7.3 million for the maintenance of water and sewage networks, connections, and systems.

· R$ 96.7 million paid to technical services, mainly IT consulting, maintenance, and support;
· R$ 51.6 million for the maintenance of water and sewage networks, connections, and systems;
· R$ 47.5 million with paving and replacing of sidewalks;

Of the total, the Free Market Tariffs (FMT) accounted for 64.6% of total expenses in 3Q23 (65.4% in 3Q22) while the Regulated Market Tariffs (RMT) accounted for 35.4% (34.6% in 3Q22).The main factors that contributed to this variation were:

Earnings
Results 3Q23

Page 8

· An average increase of 5.9% in FMT prices (including Grid Market Tariffs - TUSD), with an 11.3% decrease in consumption; and
· An average increase of 10.7% in RMT tariffs, with a decrease of 8.1% in consumption.

Due to the volatility in average costs observed in 9M23, the variation in this line came to R$ 3.1 million (0.3%).

GENERAL EXPENSES

Increase of R$ 96.6 million (+26.7%), totaling R$ 458.1 million in 3Q23, compared to the R$ 361.5 million reported in 3Q22, mainly due to:

Expenses with municipal transfers totaled R$ 221.1 million in 3Q23, compared to the R$ 193.0 million reported in 3Q22.

Expenses with the use of water totaled R$ 27.6 million in 3Q23, compared to the R$ 26.8 million reported in 3Q22.

General expenses increased by R$ 171.2 million (+17.2%) in 9M23, mainly due to:

· Increase in the provision for transfer to the Municipal Funds for Environmental Sanitation and Infrastructure, of R$ 86.3 million; and
· Increase of R$ 79.5 million in expenses with lawsuits.

DEPRECIATION AND AMORTIZATION

Increase of R$ 99.8 million (+16.3%) (R$ 239.8 million (+13.3%) in 9M23), due to the beginning of operations of intangible assets, totaling R$ 6.4 billion.

ALLOWANCE FOR DOUBTFUL ACCOUNTS

Increase of R$ 20.8 million (+15.3%), moving up from R$ 135.8 million in 3Q22 to R$ 156.6 million in 3Q23, due to the higher delinquency in 3Q23.

Reduction of R$ 60.8 million (-28.0%) year-over-year in 3Q23, primarily due to the impact of the debt negotiation fair (Feirão) held in August and September 2023.

The main impacts resulted from:

· An increase of R$ 26.0 million in interest and charges on domestic borrowings and financing, mainly due to funding from IDB Invest 2022 and IDB Invest 2023 (in July 2022 and May 2023, respectively), with an impact of R$ 21.4 million;
· An increase of R$ 7.8 million in interest and charges on international borrowings and financing, mainly due to an increase in the interest rate of some contracts with IDB and IBRD, due to the variation of the average SOFR rate (from 2.14% in 3Q22 to 5.27% in 3Q23); and
· Increase of R$ 68.2 million in other financial expenses, due to: (i) the R$ 42.0 million increase in interest charged on performance agreements, as a result of the higher number of agreements that entered the payment phase; and (ii) increased provisioning of interest charged on lawsuit, of R$ 26.3 million.

The negative effect of net monetary and exchange variations in 3Q23 was R$ 446.3 million, especially due to:

· R$ 29.3 million increase in monetary variations on borrowings and financing, due to the increase in the IPCA - Consumer Price Index (from -1.32% in 3Q22 to 0.61% in 3Q23);
· An exchange variation loss of R$ 77.2 million on borrowings and financing, due to the appreciation of the U.S. Dollar and the Yen in 3Q23 (3.9% and 0.5%, respectively), compared to the appreciation of the U.S. Dollar and the devaluation of the Yen in 3Q22 (3.2% and -3.2%, respectively);
· Increase of R$ 24.9 million in other monetary variations, mainly on lawsuits, of R$ 20.9 million; and
· Impact of R$ 314.9 million in monetary and exchange variations on assets, due to the recognition of R$ 324.5 million referring to the non-recurring monetary adjustment on the GESP 2015 agreement in 3Q22, resulting from the judicial order prohibiting the transfer of the reservoirs of the Alto Tietê Production System.

7. Income tax and social contribution

The R$ 125.9 million decrease in 3Q23 was mainly due to:

· R$ 302.9 million increase in costs and expenses; and
· Negative variation of R$ 547.4 million in the financial result.

The aforementioned factors were mitigated mainly by the R$ 465.6 million increase in net operating income.
