construction and then transferred to intangible and financial assets after conclusion of the construction work considering the contract
maturity.</P>

become available for use, at their location, and in the necessary conditions, as from when the asset operation begins. The amortization
reflects the period during which the Company expects to consume the economic benefits arising from the asset, whether corresponding to

whichever occurs first, or when there is indication of impairment.</P>

<P STYLE="font: 10pt Trebuchet MS, Times, Serif; margin: 0; text-align: justify">As disclosed in Notes 3.10(b), 15(c)(iii) and 16, with
the Concession Agreement 01/2024 between URAE-1 and the Company that came into force on July 23, 2024, a financial asset arisen from an
unconditional contractual right to receive cash or other financial asset from the concession authority as a result of construction services
(indemnity) was bifurcated. In this new model, that changed the Company's estimation on the form of realization of assets at the end of
the contract term, the Company started to be entitled to indemnity of the residual amounts of nonamortized investments in situations in
which the useful life of the asset exceeds the agreement's term, including adjustment to the inflation index contractually established,
related to reversible assets. As at December 31, 2024, the concession's financial asset amounts to R$&nbsp;17,601,626 thousand, of which
R$&nbsp;8,450,316 thousand represents the amount transferred (bifurcated) from the intangible asset recognized by its cost and R$&nbsp;9,151,310
thousand represents the Amplified Consumer Price Index (IPCA) adjustment increase, of which R$&nbsp;8,757,450 thousand is the result of
the accumulated adjustment of these assets on July, 23, 2024.</P>

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt">Sabesp
is one of the world&rsquo;s largest sanitation companies in number of customers. In 2024, it served approximately 28.1 million people
with water supply and 25.1 million with sewage services, through 9.5 million water connections and 8.2 million sewage connections.</P>

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt">In
addition to serving 375 municipalities, the Company holds a minority stake in three 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 2024 Financial Statements.</P>

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt; color: #12CDFF"><FONT STYLE="font-variant: small-caps"><B>PRIVATIZATION

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt">The
year 2024 marked a transformative moment in Sabesp's trajectory. In July, the privatization was completed, representing an opportunity
for the renewal of the Company. As a result, Sabesp became a publicly-held company with dispersed control and took on the challenge of
accelerating universalization goals to 2029.</P>

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt">This
new chapter could not have come at a more opportune time, considering the challenge ahead: to universalize basic sanitation services within
the concession area, bringing dignity, health, and quality of life to the served population. The Company's new Management is enthusiastic
about the growth and efficiency opportunities that lie ahead.</P>

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt">In
this context, the position of &quot;reference shareholder&quot; was created and is now held by Equatorial S.A., which owns 15% of the
Company's shares. As the reference shareholder, Equatorial is bound by the &ldquo;Agreement of Investment, Lock-up, and Other Covenants&quot;
with the S&atilde;o Paulo State.</P>

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt">Following
the privatization process, the Company's new Management took office on October 01, 2024, and is responsible for leading the transformation
of the &quot;New Sabesp&rdquo;. Its main challenge is to accelerate the Universalization goals for basic sanitation from 2033 to 2029,
with planned investments of approximately R$ 70 billion by 2029 and R$ 260 billion by 2060.</P>

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt">In
parallel with the privatization process, Sabesp executed a new concession agreement with the Regional Unit of Drinking Water Supply
and Sewage Services &ndash; URAE 1 &ndash; Southeast, covering 371 municipalities. This agreement incentivizes investment
acceleration by remunerating it based on its regulatory asset base and universalization goals, which will be monitored starting in
2025, as outlined in Exhibit VII of the concession agreement<FONT STYLE="font-family: Segoe UI, Helvetica, Sans-Serif; font-size: 11pt"><SUP>[1]</SUP></FONT>.
This agreement is already in effect and incentivizes Sabesp to accelerate its investments by compensating the Company based on its regulatory
asset base. In this regard, annual tariff adjustments have been established, incorporating the asset base for the first two five-year
cycles: (i) 2024 to 2029 and (ii) 2030 to 2034.</P>

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt">It
is also worth noting that, as part of a carefully structured incentive alignment to achieve the U Factor and the Q Factor, all efficiencies
that Sabesp generates regarding its regulatory operating expenses (Opex) during this first cycle will be fully retained by the Company,
without the obligation to share them in the customer tariff.</P>

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt">During
the second cycle, the focus will shift toward operational efficiencies, with specific targets related to loss reduction, at which point
the efficiencies will begin to be shared with our customers.</P>

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt">The
URAE-1 agreement stipulates that service remuneration is determined based on the actual cost structure incurred during the provision of
services and a predefined return on investment (WACC).</P>

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt">The
agreement also establishes that the equilibrium tariff will be annually adjusted during the first two tariff cycles (2024-2029 and 2030-2034),
and every five years from the third tariff cycle onwards during periodic tariff reviews. The key performance metrics of the agreement
include the previously mentioned U and Q Factors.</P>

<P STYLE="font: 11pt Segoe UI, Helvetica, Sans-Serif; text-align: justify; margin-right: 28.35pt; margin-bottom: 0; margin-left: 28.35pt">In
this context, to mitigate the impact of potential tariff increases on the population and support the necessary investment for Universalization,
the Support Fund for the Universalization of Sanitation in the S&atilde;o Paulo State (FAUSP) was established, using funds obtained from
the privatization that should be applied to ensure affordable tariffs, i.e.
to ensure that the tariff charged by Sabesp is the fairest for customers and for the Company, without compromising service quality and
efficiency.</P>

to a bifurcation of concession assets considering the contractual right that reversible and not fully amortized investments must be compensated

cause significant disruptions to the Company&rsquo;s operations or customer experience.</P>

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 assesses the positions taken in income tax filings regarding situations where the applicable tax regulations allow for interpretation
and establishes provisions, when appropriate, based on estimated amounts payable to tax authorities.</P>

<P STYLE="font: 10pt/110% Georgia, Times, Serif; margin: 0; text-align: justify">Capital is monitored based on the financial 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.</P>

Benefits, provided that the payment criteria established by the State Personnel Expenses Department (DDPE) be met, based on legal guidance

<P STYLE="font: 10pt/110% Georgia, Times, Serif; margin: 0; text-align: justify">As of November 17, 2008, the Company and the S&atilde;o
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.</P>

<P STYLE="font: 10pt/110% Georgia, Times, Serif; margin: 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt/110% Georgia, Times, Serif; margin: 0; text-align: justify">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.</P>

<P STYLE="font: 10pt/110% Georgia, Times, Serif; margin: 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt/110% Georgia, Times, Serif; margin: 0; text-align: justify">However, the recent opinions issued by the PGE received
on September 04 and 22, 2009 and January 04, 2010, denied the reimbursement of the portion previously defined as Disputed Amount.</P>

<P STYLE="font: 10pt/110% Georgia, Times, Serif; margin: 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt/110% Georgia, Times, Serif; margin: 0; text-align: justify">The third amendment also provides for the regularization
of the monthly flow of benefits. While SABESP is responsible for the monthly payments, the S&atilde;o 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 undisputed.</P>

by sending a letter resolved by the Executive Board proposing that the matter be discussed at B3&rsquo;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 S&atilde;o 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 S&atilde;o 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

of S&atilde;o 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$ 1,144,705 (R$ 1,044,035 as of December 31, 2023),
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 the Municipality may tax. Activities related to sewage services reached a favorable outcome, and
are awaiting the processing of appeals at a higher level. Regarding the ancillary activities, the annulment action was dismissed, and
the Municipality released the guarantee amount. Regarding the activities related to sanitation, the outcome was favorable, recognizing
the impossibility of charging ISS.</FONT></P>

<P STYLE="font: 10pt/110% Georgia, Times, Serif; margin: 0; text-align: justify">(*) The G1 Plan showed a surplus compared to the 2023
fiscal year, primarily due to the increase in the discount rate used to measure the actuarial liability, which went from 5.47% per year
in 2023 to 7.40% per year in 2024. This percentage was defined based on the NTN-B bond rates in effect as of December 31, 2024. The increase
in the discount rate resulted in a significant reduction in the present value of the obligations, which decisively contributed to the
observed surplus.&#9;&#9;&#9;</P>

<P STYLE="font: 10pt/110% Georgia, Times, Serif; margin: 0; text-align: justify">According to CPC 33 (R1), specifically regarding the
asset ceiling, the amount to be recognized in the statement of financial position cannot exceed the present value of any future economic
benefits available to the Company, either through cash reimbursement or reduction of future contributions. It is noted that, according
to the contractual provisions of the plan and the current legislation, there is no expectation of reimbursement within reasonable timeframes
or reduction of required contributions, meaning the surplus cannot be immediately recognized as an asset.</P>

<P STYLE="font: 10pt/110% Georgia, Times, Serif; margin: 0; text-align: justify">Therefore, the asset ceiling rule results in the limitation
of the surplus amount that can be recognized, which, in the absence of verifiable future economic benefits, must be reduced to zero, ensuring
that assets whose future realization is not supported by objective evidence are not recognized.</P>

<P STYLE="font: 10pt Georgia, Times, Serif; margin: 0; text-align: justify">According to State Law 17,853 (&ldquo;Law 17,853&rdquo;),
of December 08, 2023, which authorized the Executive Branch of the S&atilde;o Paulo State (&ldquo;State&rdquo;) to initiate measures for
the privatization of SABESP, the Support Fund for the Universalization of Sanitation in the S&atilde;o Paulo State (FAUSP) was created
to provide resources for basic sanitation initiatives, including those aimed at tariff affordability in the sector, aiming at achieving
and expediting universalization goals that ensure access to drinking water for 99% of the population and sewage collection and treatment
for 90% of the population by December 31, 2029. It also aims to meet quantitative goals for non-interruption of supply, reduction of losses,
and improvement of treatment processes, as provided for in Federal Law 11,445/2007 (&ldquo;Law 11,445&rdquo;).</P>

<P STYLE="font: 10pt Georgia, Times, Serif; margin: 0; text-align: justify">According to paragraph 1 of Article 4 of Law 17,853, the State
is required to contribute at least 30% of the net value obtained from the privatization of SABESP to FAUSP, as well as the amounts received
by the State in the form of dividends or interest on capital distributed by SABESP (Article 5 of Law 17,853). These resources should be
aimed at basic sanitation initiatives, including those aimed at tariff affordability in the sector. Accordingly, regarding this portion
to be provided by the State to fund basic sanitation initiatives, there is no accounting impact for the Company as these resources belong
to the State, with no interference or participation from SABESP in this management.</P>

<P STYLE="font: 10pt Georgia, Times, Serif; margin: 0; text-align: justify">Regarding resources aimed at tariff affordability, the mechanism
provided in the Concession Agreement of URAE-1 &ndash; Southeast is the creation of two &ldquo;Escrow accounts&rdquo;, both owned by FAUSP
and managed through the Environment, Infrastructure, and Logistics Secretariat (SEMIL). The first &ldquo;Escrow account&rdquo; will be
funded by FAUSP and reduced when equilibrium tariffs are higher than the application tariffs, after exhausting the resources of the second
&ldquo;Escrow account&rdquo;. The second &ldquo;Escrow account&rdquo;, in turn, is sensitized in 2 (two) ways.</P>

tariff lower than the equilibrium tariff is used, ARSESP will
authorize the transfer of amounts from the &ldquo;Escrow accounts&rdquo; to SABESP. Every quarter, ARSESP will inform the Bank and SABESP
of the amount to be transferred due to differences between the application tariff and the equilibrium tariff. If the application tariff
is lower than the equilibrium tariff, the Bank will make quarterly transfers to SABESP; if it is higher, SABESP will transfer to the second
&ldquo;Escrow account&rdquo; the amount informed by ARSESP every quarter. When the application tariff is higher than the equilibrium tariff,
a liability will be recognized, reducing the Company&rsquo;s operating revenue.</P>
