Highlights

Adjusted EBITDA totaled R$ 10,586 million in 3Q24 (disregards construction margin), up by R$ 8,200 million (+343.6%) over the R$ 2,387 million reported in 3Q23. Consequently, the adjusted EBITDA margin reached 78.6% compared to 46.6% in 3Q23.

Excluding the non-recurring effects and the construction margin, as described below, adjusted EBITDA totaled R$ 2,785 million in 3Q24, with an adjusted EBITDA margin of 60.0%.

Net income came to R$ 6,111 million in 3Q24, up by R$ 5,266 million (+622.2%) over the R$ 846 million recorded in 3Q23. Excluding the non-recurring effects and the construction margin, net income totaled R$ 1,173 million in 3Q24

Financial Asset (indemnity)

With the completion of the privatization process and the signing of the agreement with URAE-1, on July 23, 2024, the Company began to use the bifurcation model for assets related to the concession, previously classified solely as intangible assets. This model consists of segregating assets that will be realized through tariffs (intangible assets) and those that will be compensated (financial asset). The financial asset refers to reversible investments not fully amortized by the end of the agreement (October 2060), which will be compensated according to the contractual provision. The recording of this financial asset generated an impact of R$ 8,820 million on the period’s gross revenue. For further information, refer to Note 15 of the Quarterly Information for September 2024.

Transition

The new management decided to review the expected continuity of assets under construction (a loss of R$ 194 million). Furthermore, it reassessed the calculations of certain lawsuits (a provision of R$ 309 million recorded under General Expenses and Financial Expenses). In addition, the new management incurred expenses with transition consulting services as well as costs related to the privatization offering, totaling R$ 47 million, which are not expected to recur.

Changes in the adjusted result

a.)

NET REVENUE FROM SANITATION SERVICES

The net revenue from sanitation services, which excludes construction revenue, totaled R$ 5,462 million in 3Q24, an increase of R$ 341 million (+6.7%) over the R$ 5,120 million recorded in 3Q23.

The main factors that led to the increase were:

An impact of 4.6% in the consumption price/mix, mainly due to the net tariff adjustment of 3.6% (6.4% since May/24, net of FAUSP(*)); and

An increase of 2.0% in the total billed volume.

In September 2024, an update to the Unified Registry (Cadastro Único) database resulted in 500 thousand users qualifying for a differentiated tariff. The impact of this update was R$ 28 million, reducing the Company’s revenue (a tariff impact of 0.5%).

SALARIES, PAYROLL CHARGES AND BENEFITS, AND PENSION PLAN OBLIGATIONS

The R$ 68 million decrease (-8.5%) recorded in 3Q24 was mainly due to:

reduction of 13.1% in the average number of employees, with an impact of R$ 53 million; and

reduction of R$ 14 million in healthcare expenses.

The aforementioned decreases were partially offset by the 2.0% application in February 2024 referring to the Career and Salary Plan, and the 2.77% salary adjustment in May 2024.

SERVICES

Services fell by R$ 96 million (-13.2%) in 3Q24, of which mainly R$ 69 million in paving and replacement of sidewalks.

ELECTRICITY

Electricity expenses increased by R$ 34 million (+9.3%), mainly due to higher consumption in operations at the reservoirs, due to the period of greater drought, generating a consumption 12% higher, partially offset by gains in tariffs due to the improved mix of ACL (Free Contracting Environment) x ACR (Regulated Contracting Environment).

GENERAL EXPENSES

Increase of R$ 88 million (+19.2%), totaling R$ 546 million in 3Q24, compared to the R$ 458 million reported in 3Q23, mainly due to the higher provision for transfer to the Municipal Funds for Environmental Sanitation and Infrastructure, of R$ 71 million (pass-through), due to the new agreement of URAE-1.

Expenses with municipal transfers totaled R$ 292 million in 3Q24, compared to the R$ R$ 221 million reported in 3Q23. Expenses with the use of water came to R$ 25 million in 3Q24, compared to the R$ 28 million recorded in 3Q23.

Increase of R$ 9 million in interest and charges on international borrowings and financing, due to new IDB and IBRD fundraising;

Increase of R$ 68 million in other financial expenses, mainly due to the (i) R$ 97 million increase in interest on Public-Private Partnership - PPP; (ii) R$ 19 million increase in interest on lawsuits; and (iii) non-recurring present value adjustment of performance agreements in 3Q23, of R$ 42 million, as a result of the higher number of agreements that entered the payment phase; and

Decrease of R$ 16 million in financial revenue, mainly due to higher present value adjustment of installment payment agreements, of R$ 48 million, partially offset by the increase in revenue on financial investments in 3Q24, of R$ 40 million, due to the increase in the applied balance.

Gains with derivative financial instruments, of R$ 42 million; and

An increase of R$ 56 million in monetary variations on assets, mainly due to higher monetary variation on agreements in 3Q24.
