Introduction

We have reviewed the accompanying individual and consolidated interim financial information, contained in the Quarterly Information Form (ITR) of Cosan S.A. (“Company”) for the quarter ended March 31, 2022, comprising the statement of financial position as of March 31, 2022 and the related statements of profit or loss, of comprehensive income, of changes in equity and of cash flows for the three month period then ended, including the explanatory notes.

Officers are responsible for preparation of the individual and consolidated interim financial information in accordance with Accounting Pronouncement NBC TG 21 Demonstrações intermediárias, and IAS 34 Interim Financial Reporting, issued by the International Accounting Standards Board (IASB), as well as for the fair presentation of this information in conformity with the rules issued by the Brazilian Securities and Exchange Commission (CVM) applicable to the preparation of the Quarterly Information Form (ITR). Our responsibility is to express a conclusion on this interim financial information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and international standards on review engagements (NBC TR 2410 Revisão de Informações Intermediárias Executada pelo Auditor da Entidade and ISRE 2410 Review of Interim Financial Information performed by the Independent Auditor of the Entity, respectively). A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with auditing standards and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying individual and consolidated interim financial information included in the quarterly information referred to above are not prepared, in all material respects, in accordance with NBC TG 21 and IAS 34 applicable to the preparation of Quarterly Information Form (ITR), and presented consistently with the rules issued by the Brazilian Securities and Exchange Commission (CVM).

Emphasis of matter 

Restatement of corresponding figures

As mentioned in Note 3.1, due to change in the accounting policy adopted by the Company in 2022, the corresponding figures for the three-month period ended March 31, 2021, presented for comparison purposes, were adjusted and restated as provided for in NBC TG 23 – Políticas Contábeis, Mudanças de Estimativa e Retificação de Erro. Our conclusion is not modified in respect of this matter. 

Other matters

Statements of value added

The abovementioned quarterly information includes the individual and consolidated statements of value added (SVA) for the three-month period ended March 31, 2022, prepared under Company’s Officers responsibility and presented as supplementary information by IAS 34. These statements have been subject to review procedures performed together with the review of the quarterly information with the objective to conclude whether they are reconciled to the interim financial information and the accounting records, as applicable, and if its format and content are in accordance with the criteria set forth by NBC TG 09 Demonstração do Valor Adicionado. Based on our review, nothing has come to our attention that causes us to believe that these statements of value added were not prepared, in all material respects, according with the criteria of NBC TG 09 and consistently with the overall individual and consolidated interim financial information.

1 Operations 

Cosan S.A. (“Cosan” or “the Company”) is a publicly-traded Company on the B3 S.A. - Brasil, Bolsa, Balcão, or “B3”, on the special New Market (Novo Mercado) segment under the ticker symbol “CSAN3”. The Company’s American Depositary Shares, or “ADSs”, are listed on the New York Stock Exchange, or “NYSE”, and traded under the symbol “CSAN”. Cosan is a corporation headquartered in the city of São Paulo, state of São Paulo. Mr. Rubens Ometto Silveira Mello is the ultimate controlling shareholder of Cosan.

1.1 Recent developments and other events

1.1.1Acquisition of control of Sulgás by the subsidiary Compass Um

On January 3, 2022, the subsidiary Compass Um Participações S.A. (“Compass Um”), concluded the acquisition of 51% of the capital stock of Companhia de Gás do Estado do Rio Grande do Sul (“Sulgás”) for the amount of R$955,244, consequently obtaining control of the concessionaire, as detailed in note 8.2.

1.1.2Acquisition of control of TUP Porto São Luís by the subsidiary Atlântico Participações

On February 11, 2022 (“Acquisition Date”), the acquisition of the remaining shares of 51% of the capital stock of Porto São Luís was concluded, for the amount of R$411,224, with the transfer of control, held by São Luís Port Company S.A.R.L., a company of the China Communications Construction Company Limited (“CCCC”) group. The total amount paid for both transactions was R$804,803. With the conclusion of this stage, the Company now holds 100% of the equity interest in Porto, as detailed in note 8.2.

1.1.3 Russian-Ukrainian conflict

On February 24, 2022, Russian troops started invading Ukraine. The ongoing military attack has led, and continues to lead, to significant casualties, dislocation of the population, damage to infrastructure and disruption to economic activity in Ukraine.

In response, multiple jurisdictions, including the European Union, the United Kingdom and the United States have imposed initial tranches of economic sanctions on Russia (and in certain cases Belarus). In addition to the imposition of sanctions, a growing number of large public and private companies have announced voluntary actions to curtail business activities with Russia and Belarus. These actions include plans to dispose of assets or discontinue operations in Russia/Belarus, curtailing exports to, or imports from, these countries and discontinuing the provision of services. Moreover, the war has added to mounting concerns of a sharp global growth slowdown.

As a company that operates globally through its subsidiaries and joint venture, the ongoing conflict between Russia and Ukraine, and/or economic sanctions and import and/or export controls have not materially affected the Company’s financial statements to date. The main operations that may be affected are:

1. Fertilizer transported volumes;
2. Unfavorable conditions for obtaining fertilizers affecting sugarcane production capacity;
3. An increase in oil prices as a result of a more limited supply of Russian oil globally may also lead to a decrease of our margins and an increase in the costs of acquisition of basic inputs such as diesel oil; and
4. Measures by the Brazilian government and the Brazilian Central Bank to contain inflation, such as raising the basic interest rate, which could materially impact the cost of debt and third-party capital for our financing and investing activities.
5. Rumo's acquisition of rail tracks: Rumo of rail tracks from suppliers charged other prices and not the terms required by those suppliers may be so capable of such suppliers that Rumo has not passed.

Although the Company, its subsidiaries and joint venture do not do material business in Russia or Ukraine, we closely monitor the indirect effects that the war in Ukraine could have on international supply chains, and therefore cost of inputs and overall inflation.

Derivatives are only used for economic hedging purposes and not as speculative investments.

a)Fair value hedge

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

There is an economic relationship between the hedged item and the hedge instrument, since the terms of the interest rate and foreign exchange swap correspond to the terms of the fixed rate loan, that is, notional amount, term and payment. The Company established a 1:1 hedge ratio for hedge relationships since 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 the changes in the fair value of the hedge instrument with the 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 hedge instruments were as following:

b)Fair value option

Certain derivative instruments have not been linked to documented hedge structures.

The Company chose to designate the protected liabilities (hedge objects) to record at fair value through the income. Considering that derivative instruments are always accounted for at fair value through income, the accounting effects are the same as those obtained through a hedging documentation:

(i) The fair value of agricultural properties was determined based on the direct comparative method of market data applied to transactions with similar properties (type, location and quality of the property), and to some extent based on sales quotations for potential transactions with comparable assets (level 3). The methodology used to determine fair value takes into account direct comparisons of market information, such as market research, homogenization of values, spot market prices, sales, distances, facilities, access to land, topography and soil, use of land (type of crop) and rainfall, among other data, in line with the standards issued by the Brazilian Association of TechnicalStandards (ABNT). Significant unobservable inputs range from 6.5% p.a. and 9% p.a. on March 31, 2022.

Where all relevant criteria are met, hedge accounting is applied to remove the accounting mismatch between the hedging instrument and the hedged item. This will effectively result in recognizing interest expense at a fixed interest rate for the hedged floating rate loans and inventory at the fixed foreign currency rate for the hedged purchases.

The Company may opt for the formal designation of new debt operations for which it has swap-type derivative financial instruments for exchange variation and interest, as measured at fair value. The option for fair value is intended to eliminate or inconsistencies in the result arising from differences between the measurement credits of certain liabilities and their hedging instruments. Thus, both the swaps and the respective debts are now measured at fair value. Such option is irrevocable and must only be made in the initial accounting record of the operation.

The Company’s policy is to maintain capital base to promote the confidence of investors, creditors and the market, and to ensure the future development of the business. Management monitors that the return on capital is adequate for each of its businesses.

The usage of financial instruments in order to protect against these areas of volatility is determined through an analysis of the risk exposure that management intends to cover.

a)Market risk

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

The Company uses derivatives to manage market risks. All such transactions are carried out within the guidelines set by the risk management committee. Generally, the Company seeks to apply hedge accounting to manage volatility in profit or loss.

1. Foreign exchange risk

On March 31, 2022 and December 31, 2021, the Company had the following net exposure to the exchange rate variations on assets and liabilities denominated in U.S. Dollar (U.S.$.) and Euro:

	March 31, 2022	December 31, 2021
Cash and cash equivalents	664,088	3,811,598

(In thousands of Brazilian Reais - R$, unless otherwise stated)

The sensitivity of profit or loss to changes in the exchange rates arises mainly from U.S. dollar and Euro denominated financial instruments and the impact on other components of equity arises from foreign forward exchange contracts designated as cash flow hedges.

A reasonably possible strengthening (weakening) of the Brazilian reais to U.S. dollar and Euro as of March 31, 2022, would have affected the measurement of financial instruments denominated in a foreign currency and affected equity and profit or loss by the amounts shown below. This analysis assumes that all other variables, in particular interest rates, remain constant and ignores any impact of forecast sales and purchases. Stressed scenarios (positive and negative effects, before tax effects) were defined based on changes of a 25% and 50% to the U.S. dollar and Euro exchange rate used in the probable scenario. The Company’s exposure to foreign currency changes for all other currencies is not material:

			Variation scenario
Instrument	Risk factor	Probable	25%	50%	-25%	-50%
Cash and cash equivalents	Currency fluctuation	422,104	1,425,201	2,428,297	(580,992)	(1,584,089)

Impacts on profit or loss		1,977,849	(920,049)	(1,750,784)	(4,329,274)	1,572,158

The probable scenario considers the estimated exchange rates, made by a specialized third part, at the due date of the transactions for the companies with functional currency Brazilian reais (positive and negative, before tax effects), as follows:

	Exchange rate sensitivity analysis

2. Interest rate risk

The Company and its subsidiaries monitor the fluctuations in variable interest rates in connection with their borrowings and uses derivative instruments in order to minimize variable interest rate fluctuation risks.

A sensitivity analysis on the interest rates on loans and borrowings in compensation for the CDI investments with pre-tax increases and decreases of 25% and 50% is presented below:

		Variation scenario
Exposure interest rate	Probable	25%	50%	-25%	-50%

3. Price risk

• Financial position and unrealized gains (loss) on electricity trading operations, net

Electricity trading operations are carried out in an active market and recognized at fair value through profit or loss, based on the difference between the contracted price and the market price of open contracts at the reporting date.

This fair value is estimated, to a large extent, in the price quotations used in the active over-the-counter market, to the extent that such observable market data exist, and, to a lesser extent, by the use of valuation techniques that consider prices established in the operations of purchase and sale and market prices projected by specialized entities, in the period of availability of this information, which may not be confirmed in the future.

Statement of financial position balances referring to outstanding energy trading operations are as follows:

b)Credit risk

The Company’s regular operations expose it to potential defaults when customers, suppliers and counterparties are unable to comply with their financial or other commitments. The Company seeks to mitigate this risk by entering into transactions with a diverse pool of counterparties. However, the Company remains subject to unexpected financial failures from third parties that may affect its operations. The exposure to credit risk was as follows:

	March 31, 2022	December 31, 2021
Cash and cash equivalents	12,083,132	16,174,130
Trade receivables	3,216,733	2,745,853
Marketable securities	4,385,911	4,388,007
Restricted cash	60,725	58,990
Derivative financial instruments	2,904,458	4,732,926
Receivables from related parties	421,264	416,491
Dividends receivable and interest on equity receivables	108,583	519,965
Other financial assets	189,516	320,193
	23,370,322	29,356,555

The Company is also exposed to risks in connection with its cash management activities and temporary investments.

Net assets are invested primarily in government security and other investments in Banks with a minimum grade of “A.” Credit risk from balances with banks and financial institutions is managed by the Company’s treasury department in accordance with the Company’s policy.

The credit risk of lease receivables is classified into two categories of customers: (i) Level 1 and (ii) Level 2. Most investment properties of subsidiaries are leased to customers classified as Level 1, with no history of late payment or default and with a sound financial situation. To mitigate the credit risk related to lease receivables, the Company's policy limits its exposure to Level 2 customers to a minimum.

For accounts receivable related to the sale of investment properties, the risk is mitigated by granting ownership of land to the customer only when a down payment for the transaction is received. In addition, title to ownership is transferred only upon receipt of outstanding payments in full.

Investments of surplus funds are made only with approved counterparties and within credit limits assigned to each counterparty. Counterparty credit limits are reviewed on an annual basis and may be updated throughout the period. The limits are set to minimize the concentration of risks and therefore mitigate financial loss through potential counterparty’s failure to make payments. The credit risk on cash and cash equivalents, marketable securities, restricted cash and derivative financial instruments are determined by rating instruments widely accepted by the market and are arranged as follows:

	March 31, 2022	December 31, 2021
AAA	17,041,518	23,080,390
AA	2,171,466	2,239,266
A	83,916	—
BBB	36,028	34,397
Not rated	101,298	—
	19,434,226	25,354,053

c)Liquidity risk

The Company’s approach to managing liquidity is to ensure, as far as possible, that it will have sufficient liquidity to meet its liabilities when they are due, under both normal and stressed conditions, without incurring unacceptable losses or risking damage to the Company’s reputation.

The financial liabilities of the Company sorted by due dates (based on undiscounted cash flows contracted) are as follows:

d)Capital management risk

The Company's policy is to maintain a solid capital base to promote the trust of its parent companies, creditors and the market, and to ensure the future development of the business. Management monitors the return on capital, which is defined by the Company as the result of its operating activities divided by the total shareholders' equity, so that it is adequate for each of its businesses.

8.2 Acquisition of subsidiaries

Sulgás

On January 3, 2022, Compass Gás e Energia S.A., through its subsidiary Compass Um Participações S.A. (“Compass Um”) concluded the acquisition of 51% of the capital stock of Companhia de Gás do Estado do Rio Grande do Sul (“Sulgás”) owned by the State Government of Rio Grande do Sul for the amount of R$955,244. As of that date, Sulgás began to be consolidated in the Company's financial information.

Sulgás is located in the city of Porto Alegre, and its main activity is the distribution of piped natural gas in the State of Rio Grande do Sul and operates this service exclusively through a concession model valid until August 2044. Its network of distribution totals approximately 1,400 km, serving more than 68,000 customers in 42 municipalities, with a distributed volume of 2 million m3/day.

In the preliminary assessment carried out by the Company, the acquisition price was allocated as a concession right for gas distribution. The table below shows the consideration paid, the fair value of the assets acquired, and liabilities assumed on the acquisition date.

Labor claims: The Company and its subsidiaries are also parties to a number of labor claims filed by former employees and service providers challenging, among other matters, the payment of overtime, night shift premiums and risk premiums, the recognition of employment relationships and the reimbursement of discounts from payroll, such as social contribution and trade union charges. Additionally, we are involved in several labor administrative and judicial proceedings such as labor investigations and class actions filed by the labor prosecutor’s office regarding alleged non-compliance with certain labor regulations, including work and safety rules, labor conditions and work environment, and social assistance plans. Moreover, we entered into certain consent orders (Termos de Ajustamento de Conduta) with Brazilian authorities and, in the event, we fail to comply with such consent orders, we could be subject to fines.

Civil, Environmental and Regulatory Proceedings: The Company and its subsidiaries have several indemnity claims, public civil claims and administrative proceedings that individually are not material, where, in the opinion of its lawyers, the risk of loss is probable.

Dilutive instruments

The Company’s subsidiaries have two categories of potential dilutive effects: share options and put options. For the share options, a calculation is done to determine the effect of the dilution in the profit attributable to shareholders of the parent due the exercise of the share options at subsidiaries. For the put option, is assumed to have been converted into ordinary shares, and the profit attributable to shareholders of the parent is adjusted.

Anti-dilutive instruments

In the period ended March 31, 2022, 45,765,000 shares related to the Company's share buyback plan were not considered in the diluted earnings per share analysis, as they increase earnings per share
