INDEPENDENT AUDITOR’S REVIEW REPORT ON THE INDIVIDUAL AND CONSOLIDATED INTERIM FINANCIAL INFORMATION

To the

Shareholders, Board Members and Management of

Cosan S.A.

São Paulo - SP

Introduction

We have reviewed the individual and consolidated interim financial information of Cosan S.A. (“Company”), included in the quarterly information, for the quarter ended June 30, 2024, which comprises the individual and consolidated interim statement of financial position as at June 30, 2024, and the respective individual and consolidated interim statements of profit or loss and comprehensive income for the three- and six-month periods then ended, and the of changes in equity and cash flows for the six-month period then ended, including the notes to the financial information.

The Company’s and its controlled companies’ Management is responsible for the preparation of this individual and consolidated interim financial information in accordance with NBC TG 21 (R4) and with International Accounting Standard (IAS) 34 - Interim Financial Reporting, issued by the International Accounting Standards Board (IASB), and for the presentation of this interim financial information in accordance with the standards issued by the Brazilian Securities and Exchange Commission (CVM) applicable to quarterly information. Our responsibility is to express a conclusion on the individual and consolidated interim financial information based on our review.

Scope of the review

We conducted our review in accordance with Brazilian and international standards on review engagements (NBC TR 2410 and ISRE 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity). A review of interim financial information consists principally of applying analytical and other review procedures and making enquiries of and having discussions with persons responsible for financial and accounting matters. An interim review is substantially less in scope than an audit conducted in accordance with auditing standards and does not provide assurance that we would become aware of any or all significant matters that might be identified in an audit. Accordingly, we do not express such an audit opinion.

Conclusion on the individual and consolidated interim financial information

Based on our review, we are not aware of any fact that would leads us to believe that the individual and consolidated interim financial information included in the accompanying Quarterly Information has not been prepared, in all material respects, in accordance with NBC TG 21 (R4) and IAS 34, applicable to the preparation of the Quarterly Information, and presented in accordance with the standards issued by CVM.

Other matters

Individual and consolidated interim statements of value added – Supplementary information

The interim financial information referred to above includes the individual and consolidated statements of value added for the six-month period ended June 30, 2024, prepared under the responsibility of the Company's Management and presented as supplementary information for the purposes of IAS 34. These statements were submitted to review procedures executed with the review of the quarterly information, with the purpose of concluding whether they are reconciled with the interim financial information and accounting records, as applicable, and if its form and contents meet the criteria defined in NBC TG 09 – Statement of Value Added. Based on our review, we are not aware of any fact that would lead us to believe that these statements of value added were not prepared, in all material respects, in accordance with the criteria established in this standard and consistently with the individual and consolidated interim financial information taken as a whole.

Interim financial information for the previous quarter reviewed by another independent auditor

The corresponding amounts related to the individual and consolidated interim financial information for the quarter ended June 30, 2023, originally prepared before the reclassifications disclosed in Note 3.1, were reviewed by other independent auditors and their review report issued, without modification, in August 14, 2023. We also reviewed the reclassifications described in Note 3.1 that were carried out to change the corresponding values relating to the individual and consolidated interim financial information for the three and six-month period as of June 30, 2023. In our conclusion, such reclassifications are appropriate and were correctly carried out. We were not engaged to audit, review or apply any other procedures to the Company's individual and consolidated interim financial information for the corresponding three and six-month period ended June 30, 2023 and, therefore, we do not express an opinion or any form of assurance regarding this individual and consolidated interim financial information, taken as a whole.

The accompanying financial information has been translated into English for the convenience of readers outside Brazil.

3.1. RECLASSIFICATION IN THE INCOME STATEMENT

ARSESP, through resolution 1,205 of August 18, 2021, NTF-044-2021, released a new Regulatory Accounting Manual and Chart of Accounts for the piped gas distribution sector for companies on its regulation with applicability as of fiscal year 2023.

According to the technical note mentioned above, ARSESP determines that the accounting of variations, positive and negative, between the price included in the tariffs and the price actually paid by the concessionaire to the supplier, which are periodically passed on to users through graphical accounts, must be recorded in the net operating revenue group. The accounting policy usually applied by the subsidiary Compass is consistent with the understanding of the essence of the operation, classifying the effects of the Regulatory Current Account ("CCR") on its gross income, but with allocations in the cost group of goods sold and services rendered. In addition, the document also mentions that the classification of expenses and costs may vary in relation to commonly adopted practices in which part of the administrative expenses are also admitted as costs of operations related to piped gas distribution services.

The indirect subsidiary Comgás has voluntarily reassessed the way in which it presents the classification of the effects of CCR and general and administrative expenses, as it understands that such presentation will meet the requirements of ARSESP and OCPC08, providing more consistent information in the consolidations in line with the practices adopted by the group. These reclassifications do not impact the main indicators, such as profit for the year and shareholders' equity, used by the indirect subsidiary Comgás and the other gas distributors of Compass.

The application of the change in the accounting policy generated the following reclassification in the income statement in the comparative period:

(viii)	The 11th, 12th and 13th issues debentures have a contractual leverage ratio limited to 3.0x. However, they have a prior consent (waiver) that allows the broadcaster to extrapolate this index up to the limit of 3.5x until December 31, 2027.

For debts linked to derivatives, the effective rates are shown in the explanatory note 5.6.

To calculate the average rates, on an annual basis, the average annual CDI rate of 10.40% p.a. was considered. (11.65% p.a. on December 31, 2023) and TJLP of 6.67% p.a. (6.55% p.a. on December 31, 2023).

All debts with maturity dates denominate in foreign currency are hedged against foreign exchange risk through derivatives (note 5.6), except for perpetual notes.

Loans, financing and debentures that are classified as non-current have the following maturities:

e)Offset of assets and liabilities

SENIOR NOTES INTERNALIZATION 2031

On February 16, 2024, the Company interned the remaining funds from the 2031 senior notes, through the issuance of Loan 4131 by Cosan S.A., referenced in U.S. dollars in the amount of equivalent to US$600,000 thousand, equivalent to R$2,982,600, with an annual coupon of 6.6% p.a. for the first four semesters and interest payments of 7.25% p.a. for the others. On the other hand, Cosan Luxembourg contracted a Time Deposit ("TD") with the same amount and counterparty in US dollars, with a frequency of semi-annual payments and an annual remuneration of 7.25% p.a., which has as its underlying asset the issuance of Loan 4131.

(i) The amounts are equivalent to US$898,000 thousand, with the PTAX conversion rate of June 28,2024 being R$5.5589.

Since the Company has the legally enforceable right to offset the amounts and intends to settle them simultaneously, for consolidation purposes, the Company offset the assets related to the TRS contract with the debt liabilities arising from the debentures and the Time Deposit with the Loans 4131, presenting them at net value, as well as their respective impacts on the income statement. Thus, no sensitivity analysis is carried out as both transactions do not pose a risk to the Company.

f)Fair value and exposure to financial risk

The fair value of loans is determined by discounting future cash flows at their implied discount rate. Due to the use of unobservable inputs, including own credit risk, they are classified as fair value at level 2 of the hierarchy (Note 5.11).

Details of the Company's exposure to risks arising from loans are shown in Note 5.12.

Notes to the interim Financial Statements

(InthousandsofReais,exceptwhenotherwiseindicated)

The lease agreements have different terms, with the last due date occurring in December 2058. The amounts are updated annually by inflation indexes (such as IGPM and IPCA) or may incur interest calculated based on the TJLP or CDI and some of the contracts have renewal or purchase options that were considered in determining the term and classification as finance lease.

In addition to the amortization and appropriation of interest and exchange variation highlighted in the previous tables, the following impacts on income were recorded for the other lease contracts that were not included in the measurement of lease liabilities.

	2Q24	2Q23	6M24	6M23
Variable lease payments not included in the recognition of lease obligations	13,252	10,646	25,248	21,709
Expenses related to short-term leases	5,264	3,448	12,957	5,593
Low asset leasing costs, excluding short-term leases	2,624	297	5,177	651
	21,140	14,391	43,382	27,953

The lease balances recorded by the Company include the contract for the indirect subsidiaryRumoMalhaCentral and the amendment to renew the contract for the indirect subsidiaryRumoMalhaPaulista, which have an identified implicit rate and are, therefore, readily determinable in such cases. In other words, in these cases the valuation does not generate the distortions in the liabilities and right of use object of CVM Circular Letter 2/2019. This particularity of the Company means that the effects on the balances (of lease liabilities, right of use, financial expenses and depreciation expenses) if the measurement were made by the present value of the expected installments plus projected future inflation, would not are relevant to influence users' decisions and, consequently, to be presented in the financial statements.

The Company recorded lease liabilities at the present value of the installments due, that is, including any tax credits to which it will be entitled at the time of payment of the leases. The potential PIS/COFINS credit included in liabilities on June 30, 2024 is R$28,596 (R$32,244 at December 31, 2023).

Notes to the interim Financial Statements

(InthousandsofReais,exceptwhenotherwiseindicated)

a)Fair value hedge

The Company adopts fair value hedge accounting for some of its operations, both the hedging instruments and the hedged items are measured and recognized at fair value through profit or loss.

There is an economic relationship between the hedged item and the hedging instrument as the terms of the interest rate and exchange rate swap correspond to the terms of the fixed rate loan, i.e. notional amount, term and payment. The Company established a 1:1 coverage ratio for the hedging relationships, as the underlying risk of the interest rate and exchange rate swap is identical to the hedged risk component. To test the effectiveness of the hedge, the Company uses the discounted cash flow method and compares changes in the fair value of the hedging instrument with changes in the fair value of the hedged item attributable to the hedged risk. The sources of hedge ineffectiveness that are expected to affect the hedging relationship during its term evaluated by the Company are mainly: (i) reduction or modification of the hedged item; and (ii) a change in the credit risk of the Company or the counterparty of the contracted swaps. The amounts related to the items designated as hedging instruments were as follows:

b)Fair value option

Certain derivative instruments were not designated to documented hedging structures.

The Company chose to designate the hedged liabilities (hedge objects) to be recorded at fair value through profit or loss. Considering that derivative instruments are always accounted for at fair value through profit or loss, the accounting effects are the same as those that would be obtained through hedging documentation:

c)Cash flow hedge

Compass

Natural gas purchase and sale contracts

The indirect subsidiary Edge Comercialização S.A. entered into natural gas sale agreements (BRENT risck) with a third party and related party. In order to protect and mitigate the risks arising from fluctuations in natural gas indexes, the subsidiary designated this operation subject to hedge accounting for the respective cash flow protection.

In this contracting, the expected benefits are: reducing the financial risk associated with fluctuations in natural gas prices, avoiding fluctuations in the financial result of hedge instruments, protecting the subsidiary's margins, as well as maintaining predictability in its costs or revenues, ensuring greater stability in operating results.

Highly probable revenues in US dollars (Leasing)

The indirect subsidiary TRSP adopted a hedge accounting strategy to protect its results from exposure to variability in cash flows arising from the exchange rate effects of highly probable revenues in US dollars projected for a period of 20 years, through non-derivative hedging instruments – lease liabilities in US dollars already contracted.

On June 30, 2024, an ineffective portion related to Brent was reclassified to the financial result in the amount of R$2,421. The impacts recognized in the TRSP's equity and the estimated realization are as below:

(i)

The fair value of investment properties was determined using the direct comparative method of market data applied to transactions involving similar properties (type, location, and quality of property) and, to a lesser extent, sales quotes for potential transactions involving comparable assets (level 3). The methodology used to determine fair value incorporates direct comparisons of market information, such as market research, homogenization of values, spot market prices, sales, distances, facilities, access to land, topography and soil, land use (crop type), and rainfall, among other data, in accordance with the standards issued by the Brazilian Association of Technical Standards ("ABNT"). The discount rates used vary between 11.12% p.a. and 11.20% p.a. on June 30, 2024 and on December 31, 2023.

(ii)

The fair value of the Company's loans does not differ significantly from their carrying value, except for debts that are assigned to fair value through profit or loss. For debts that have a market value quoted on the Luxembourg Stock Exchange, the fair value measurement is based on the quoted market price as follows:

The Company's Management identifies, evaluates, and hedges financial risks in close collaboration with operating units. The Board of Directors provides written principles for managing global risk in addition to policies covering specific areas such as currency risk, interest rate risk, credit risk, use of derivative and non-derivative financial instruments, and excess investment of liquidity.

When all applicable criteria are satisfied, hedge accounting is used to eliminate the accounting mismatch between the hedging instrument and the hedged item. This will result in the effective recognition of interest expense at a fixed interest rate for hedged floating rate loans and inventory at the fixed foreign exchange rate for purchases hedged against foreign exchange risk.

The Company may opt for formal designation of new debt transactions for which it has swap-type derivative hedging instruments for foreign exchange rate variation and interest, as measured at fair value. The Fair Value Option is intended to eliminate inconsistencies caused by disparities between the measurement credits of certain liabilities and their hedging instruments. Consequently, both swaps and respective debts are now valued at fair value. This option is irrevocable and must be exercised upon the operation's initial accounting entry.

The policy of the company is to maintain a sufficient capital base to foster the confidence of investors, creditors, and the market, and to ensure the business's future growth. Each of its businesses' rate of return on capital is monitored by Management.

An analysis of the risk exposure that Management intends to cover determines the use of financial instruments to protect against these areas of volatility.

Notes to the interim Financial Statements

(InthousandsofReais,exceptwhenotherwiseindicated)

a)Market risk

The objective of market risk management is to manage and control exposures to market risk within acceptable parameters, optimizing returns.

The Company uses derivatives to manage market risks. All these transactions are carried out within the guidelines defined by the Risk Management Committee. Generally, the Company seeks to apply hedge accounting to manage volatility in profit or loss.

i.           Foreign exchange risk

As of June 30, 2024 and December 31,2023, the Company had the following net exposure to foreign exchange variation on assets and liabilities denominated in US Dollars, Euros, Yen and Pound Sterling:

	06/30/2024	12/31/2023
Cash and cash equivalents	826,357	284,956
Suppliers	(672,733)	(441,768)
Loans, financing and debentures	(18,522,248)	(24,861,084)
Leases	(1,852,363)	(1,627,104)
Consideration payable	(196,188)	(203,094)
Derivative financial instruments	24,044,414	14,182,102
FX exposure, net	3,627,239	(12,665,992)

The probable scenario considers the estimated foreign exchange rates, carried out by a specialized third party, at the maturity of transactions for companies with real functional currency (positive and negative, before tax effects), as follows: 

			Scenarios
Instrument	Risk factor	Probable	25%	50%	(25%)	(50%)

ii.Interest rate risk

The Company and its subsidiaries monitor fluctuations in variable interest rates related to their financing and use derivative instruments to minimize the risk of fluctuations in variable interest rates.

Notes to the interim Financial Statements

(InthousandsofReais,exceptwhenotherwiseindicated)

• Options

We use derivative financial instruments called options to limit our exposure to changes in the value of Vale shares. The widely accepted methodology used to calculate the fair value of options is based on the Black & Scholes pricing model. The values calculated in the sensitivity analysis of the framework mentioned reflect the impacts of the intrinsic values of the options as the shares appreciate or depreciate.

		Scenarios
Instrument	Interest	Probable	25%	50%	(25%)	(50%)
VALE3 (Call Spread)	1.43%	238,986	534,402	747,253	117,251	31,344

• Call Option (“Call”)

The Company has a call option which gives it the right to repurchase all the preferred shares of Cosan Nove and Cosan Dez, which may be exercised as of the third year after the execution of the respective agreements in December 2022.

As of June 30, 2024, the Company measured the fair value of the call option and concluded that it is off price.

• Contingent put option

In the shareholders' agreements entered into between the Company and the banks Itaú and Bradesco regarding the issuance of preferred shares, it was defined that both financial institutions have a contingent put option only when the specific adverse material effects provided for in the contract occur, which are in the Company's control and, therefore, do not constitute a financial obligation.

The prices of the exercise options are calculated based on the initial values of R$4,115,000 and R$4,000,000 adjusted by a weighted average rate of CDI + 1.25% minus the dividends received by non-controlling shareholders in this period, which, as of June 30, 2024, is represented by the amounts of R$4,360,046 and R$3,836,565, respectively.

• Total Return Swap (TRS)

We are exposed to risks linked to CSAN3 share prices. To mitigate such exposures, total return swap derivatives of 113,348,712 shares of CSAN3 were contracted in which the Company receives the variation of the share price and proceeds on the active side and pays CDI + 1.42% on the passive side.

The sensitivity analysis considers the closing share price as shown below:

		Scenarios
Instrument	Probable	25%	50%	(25%)	(50%)
Brent derivatives – options	(732,552)	383,685	767,371	(383,685)	(767,371)
Value of the share (CSAN3)	13.54	16.93	20.31	10.16	6.77

b)Credit risk

The Company's regular operations expose it to the risk of default when customers, suppliers, and counterparties are unable to fulfill their financial commitments or other obligations. The Company seeks to mitigate this risk by conducting transactions with a diverse group of counterparties. However, the Company's operations remain susceptible to the unanticipated financial failures of third parties. The credit risk exposure was as follows:

Cash and cash equivalents	17,230,061	14,658,481
Trade receivables	4,221,926	3,444,636

Other financial assets	4,194	3,113
	28,920,797	24,956,110

The Company is exposed to risks related to its cash management activities and temporary investments.

The majority of liquid assets are invested in government bonds and other bank investments. The treasury department manages the credit risk of bank and financial institution balances in accordance with the Company's policy.

The credit risk associated with lease receivables is divided into two customer categories: (i) Level 1 and (ii) Level 2. The majority of subsidiary investment properties are leased to customers classified as Level 1, with no history of late payments or default and a solid financial standing. In order to mitigate the credit risk associated with lease receivables, the Company's policy restricts its exposure to Level 2 customers. The risk associated with accounts receivable related to the sale of investment properties is mitigated by granting land ownership to the customer only after receiving a down payment for the transaction. In addition, the transfer of ownership is contingent upon receipt of all outstanding payments.

Only approved counterparties and within the credit limits assigned to each counterparty may invest surplus funds. Credit limits for counterparties are reviewed annually and may be modified throughout the period. The limits are established to minimize the concentration of risks and, consequently, to mitigate financial loss caused by potential counterparty default. The credit risk of cash and cash equivalents, marketable securities, restricted cash, and derivative financial instruments is determined by widely accepted market rating instruments and is structured as follows:

	06/30/2024	12/31/2023
AAA	23,133,257	20,475,536
AA	201,005	172,871
A	529,684	124,932
Not rated	165,846	139,154
	24,029,792	20,912,493

c)Liquidity risk

The Company's strategy for managing liquidity is to ensure, whenever possible, that it has sufficient liquidity to meet its liabilities when they are due, under normal and stressed conditions, without incurring unacceptable losses or risking reputational harm.

The Company's financial liabilities (based on contracted undiscounted cash flows) are categorized by maturity dates as follows:

d)Capital management risk

The group manages the capital structure and adjusts it in light of changing economic conditions and financial covenant requirements. In order to maintain or adjust the capital structure, the Group may adjust the payment of dividends to shareholders, return capital to them or issue new shares. The Company monitors capital mainly through the leverage ratio, calculated as net debt to EBITDA. The group's lowest covenant ratio is currently 3.3x.

The Company's policy is to maintain a solid capital base to foster the confidence of its parent companies, creditors, and the market, and to ensure the business's future growth. Management ensures that the return on capital, which the Company defines as the result of its operating activities divided by its total shareholders' equity, is sufficient for each of its businesses.

To achieve this overall objective, the Group's capital management, among other things, aims to ensure compliance with the financial commitments associated with the loans and financing that define the capital structure requirements.

b)  Capitalization of borrowing costs

In the period ended June 30, 2024, the borrowing costs capitalized by the subsidiary Rumo were R$29,699 at an average rate of 11.23% (R$25,168 and 12.49% p.a. on June 30, 2023), while in the subsidiary Compass the capitalized costs were R$39,617 at a weighted average rate of 7.36% p.a. (R$53,963 and 8.92% p.a. in the period ended June 30, 2023).

c)Write-off of assets and impairment loss of indirect subsidiary Rumo Malha Sul

As mentioned in note 2 Material events, the subsidiary Rumo identified the residual value of the assets with traffic directly interrupted by the weather events and provisioned the amount of R$2,392,776 (note 21), considering that the assets were destroyed or their use was made impossible for an indefinite period.

The extent of the damage raises uncertainties about the process of renewing the concession, which initially expires in February 2027, although Rumo continues to make its best efforts in this regard.

In this context, in the quarter ended June 30, 2024 and in accordance with Circular Letter No. 01/2024-CVM/SNC/SEP, Management identified the existence of indications that led to the realization of the recoverability test of the non-current assets (fixed assets, intangibles and rights of use) of the cash-generating unit of the subsidiary Rumo ("Rumo Malha Sul"), considering the event described above and the term of use of the assets.

For this assessment, the recoverable value of the unit was determined based on its value in use, obtained by discounted cash flow, based on updated projections approved by management. The main assumptions were:

• Projection period: until February 2027.
• Sales volume: a fall of 2.1% is expected in the indirect subsidiary Malha Sul in 2025, followed by annual growth of 0.9% over the rest of the period, based on management's expectations for market development.
• Selling price: considers the average annual growth rate of 3.1%, and is based on current industry trends and includes inflation forecasts for Brazil.
• Variable costs and maintenance: included according to history and without capacity increases.
• Projected investments: refer to the maintenance of the Concession and are based on the historical experience of the management of the subsidiary Rumo. Investments do not include capacity increases. No incremental revenue or cost savings were considered in the value-in-use model as a result of this expenditure.
• The nominal discount rate of 11.22%, estimated by the weighted average cost of capital.

On June 30, 2024, the value in use of the cash-generating unit of the subsidiary Rumo (R$980,352) is less than the book value of its property, plant and equipment, intangible assets and rights of use by R$2,392,776, and a provision for impairment was recorded, allocated as follows: R$2,223,765 in Property, plant and equipment, R$3,972 in Intangible assets (note 11.2) and R$165,039 in Rights of use (note 11.4).

Diluting instruments

The Company and its subsidiaries have two categories of possible dilutive effects: stock grants and put options. For stock grants, a calculation is performed to determine the impact of dilution on the profit attributable to the Parent Company's shareholders as a result of the exercise of stock grants in subsidiaries. It is assumed that the put option was converted into common stock, and the profit attributable to the Parent Company's shareholders is adjusted accordingly.

Anti-dilution instruments

In the period ended June 30, 2024, 9,143,952 shares related to the Company's stock option plan were not considered in the analysis of diluted earnings per share, as they decrease the loss per share. (6,354,535 shares as of June 30, 2023).
