To the Shareholders of

Cosan S.A.

São Paulo - SP

Opinion

We have audited the individual and consolidated financial statements of Cosan S.A. (the “Company”), identified as individual and consolidated, respectively, which comprise the statement of financial position as at December 31, 2022, and the respective statement of profit or loss, of comprehensive income, of changes in equity, and of cash flows for the year then ended, and as well as the corresponding notes, including a summary of significant accounting policies.

In our opinion, the financial statements referred to above present fairly, in all material respects, the individual and consolidated financial position of the Company as at December 31, 2022, and its individual and consolidated financial performance and cash flows for the year then ended, in accordance with accounting practices adopted in Brazil and with the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB).

Basis for opinion

We conducted our audit in accordance with the Brazilian and International Standards on Auditing. Our responsibilities under those standards are further described in the “Auditor’s responsibilities for the audit of the individual and consolidated financial statements” section of our report. We are independent of the Company and its subsidiaries in accordance with the relevant ethical principles set forth in the Code of Professional Ethics for Accountants and the professional standards issued by Brazil’s National Association of State Boards of Accountancy (CFC), and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Emphasis of matter

Restatement of corresponding figures

According to Note 3.3, which describes the effects of the change in the accounting practice adopted by the Company in 2022, the corresponding figures referred to the year ended December 31, 2021, presented for comparison purposes, were adjusted and are being restated, as provided for in NBC TG 23 / IAS8 – Políticas Contábeis, Mudanças de Estimativa e Retificação de Erro. Our opinion is not modified in respect of this matter.

Key audit matters 

Key audit matters are those that, in our professional judgment, were of most significance in our audit of the financial statements of the current year. These matters were addressed in the context of our audit of the individual and consolidated financial statements as a whole, and in forming our opinion thereon, and we do not provide an individual opinion on these matters. For each matter below, our description of how our audit addressed the matter, including any commentary on the findings or outcome of our procedures, is provided in that context.

We have fulfilled the responsibilities described in the “Auditor’s responsibilities for the audit of the individual and consolidated financial statements” section of our report, including in relation to these matters. Accordingly, our audit included the performance of procedures designed to respond to our assessment of the risks of material misstatement of the financial statements. The results of our audit procedures, including the procedures performed to address the matters below, provide the basis for our audit opinion on the Company’s financial statements.

Acquisition of noncontrolling interest in Vale S.A.

As disclosed in Note 1.2.6 to the financial statements, the Company, through its subsidiary Cosan Oito S.A., concluded, on October 14, 2022, the acquisition of a non-controlling interest equivalent to 4.86% in Vale S.A. (“Vale”), for the amount of R$16,924,680 thousand. The investment acquisition was made through debt obtained. Additionally, the Company contracted derivative instruments to hedge itself against the risk of depreciation of Vale’s shares referring to its 3.31% interests, consisting of a combination of call and put positions (collar), in addition to contracting a collar call spread to hedge its right to acquire an additional 1.6% equity interests in Vale.

This matter was considered significant for our audit due to the complexity and volatility of certain financial instruments involved, and the relevance of amounts involved in relation to the Company’s financial statements.

4

How our audit addressed this matter

Our audit procedures included, among others: i) general understanding of the internal control environment including the accounting policies adopted by the Company regarding the acquisition of the non-controlling interest in Vale; ii) involvement of most experienced audit professionals in defining the test strategy, evaluating the audit supporting documentation and supervising the audit procedures performed; iii) involvement of our experts in derivative financial instruments to assist us in the reasonableness tests on the assessment and accounting treatment of these financial instruments; iv) reading of contracts and other documents relevant to the transaction; and v) recalculation of the fair value of financial instruments.

Based on the result of the audit procedures performed on the acquisition of non-controlling interest in Vale S.A., which is consistent with management’s assessment, we consider that the related accounting policies, criteria and assumptions adopted by management are appropriate in the context of the financial statements taken as a whole. We also assessed the adequacy of the disclosures made by the Company in Note 1.2.6 to the financial statements.

Business combinations

As disclosed in Note 8.2 to the financial statements, during the year ended December 31, 2022, the Company’s subsidiaries, Compass Gás e Energia S.A., Atlântico Participações Ltda., Cosan Lubrificantes e Especialidades S.A. and Millennium Moove Corp. carried out business combinations for the acquisition of Companhia de Gás do Estado do Rio Grande do Sul e Commit Gás e Energia S.A, TUP Porto São Luís S.A., Tirreno Indústria e Comércio de Produtos Químicos Ltda. and Stryker Intermediate Holdings, respectively. Additionally, the Company acquired the control of Tellus Brasil Participações S.A., Janus Brasil Participações S.A., Gamiovapar Empreendimentos e Participações S.A. and Duguetiapar Empreendimentos e Participações S.A. The consideration transferred related to these acquisitions, net of cash acquired and non-controlling interests, consolidated, was R$5,288,696 thousand, intangible assets of R$4,508,809 thousand, goodwill of R$402,055 thousand and gain on bargain purchase of R$99,341 thousand before income tax and social contribution. As a result of these procedures, audit differences were identified which, when material to the financial statements taken as a whole, were adjusted by management.

This matter was considered significant for our audit, due to judgments involved in the identification and determination of the fair value of assets acquired and liabilities assumed, and the consequent determination of goodwill or gain on bargain purchase. In addition, the amounts involved in these transactions are significant in relation to the Company’s financial statements as at December 31, 2022.

How our audit addressed this matter

Our audit procedures included, among others: i) the execution of audit procedures of the opening balances of the acquired companies on the acquisition date as part of the determination of the fair values of acquired assets and liabilities assumed; ii) review of the alignment of the Company’s accounting practices with those of the acquired companies; iii) reading of contracts and other documents relevant to the transaction; and iv) involvement of our corporate finance experts to assist us in the assessment of assumptions and methodologies used by management in measuring and recognizing the fair value of assets acquired and liabilities assumed, and calculation of goodwill or the gain on bargain purchase.

5

Based on the result of the audit procedures performed, which is consistent with management’s assessment, we consider that the Company’s accounting policies related to business combination are appropriate to support the judgments and information included in the context of the financial statements taken as a whole. We also evaluated the adequacy of related disclosures made by the Company in Note 8.2 to the financial statements.

Railway’s concession infrastructure

As disclosed in Note 10.1 to the financial statements, as at December 31, 2022, the Company has recorded in its property and equipment certain assets directly related to the railway concession infrastructure in its subsidiary Rumo S.A., including wagons, locomotives and trackway which amount to R$11,290,894 thousand. The amounts invested in assets related to the railway’s concession infrastructure are significant and essential for the maintenance of the infrastructure used in the rendering of the railway transportation service.

This matter was considered significant for our audit due to the amounts involved in relation to the Company’s financial statements as at December 31, 2022, relevance of additions for the year, and risk that such assets are improperly capitalized.

How our audit addressed this matter

Our audit procedures included, among others: i) a general understanding of the internal control environment, including the criteria adopted to determine the applicability of capitalization; ii) assessment of the nature of capitalized expenditures; iii) extensive testing, on a sample basis, of materials and services applied to the construction works; iv) monitoring of the progress of construction works through on-site physical inspections; v) evaluation of the policies established by the Company for such accounting and their applicability to current accounting standards; and vi) interest capitalization test.

Based on the result of audit procedures performed, which is consistent with management’s assessment, we consider that the criteria and capitalization accounting policies of the assets related to railway concession infrastructure are appropriate in the context of the financial statements taken as a whole. We also evaluated the adequacy of related disclosures made by the Company in Note 10.1 to the financial statements.

Public concession infrastructure referring to the gas distribution service

As disclosed in Notes 10.2 and 10.3 to the financial statements, as at December 31, 2022, the Company has recorded intangible asset of the public concession and contract asset related to the gas distribution service, in the amounts of R$11,614,163 thousand and R$1,110,335 thousand, respectively, referring to the infrastructure of this concession in the subsidiary Compass Gás e Energia S.A.

6

These investments in concession infrastructure are an essential part of the methodology applied by the granting authority to define the tariff to be charged by the Company to end consumers, under the terms of the Service Concession Arrangement. The definition of which expenditures are eligible and should be capitalized as infrastructure cost as well as the definition of useful life are subject to the executive board’s judgment.

This matter was considered significant for our audit due to particularities in connection with the capitalization process and subsequent assessment of infrastructure expenditures, in addition to the significance of the amounts involved.

How our audit addressed this matter

Our audit procedures involved, among others: i) understanding of the process implemented by management on the accounting for investments in public concession infrastructure related to the gas distribution service, including its classification as an asset qualifying for capitalization; ii) assessment of the nature of these investments with the applied infrastructure; iii) tests on a sample basis of the materials and services applied to the works, as well as the allocation of workforce hours; iv) assessment of the accounting classifications between the contract asset and the intangible asset entitled to this concession, observing the periods of the works; v) the policies established by the Company for such accounting and their applicability to current accounting standards; vi) the interest capitalization, when applicable; vii) use of substantive analytical procedures on additions and amortization; and viii) amortization test of the intangible asset entitled to this concession.

Based on the result of audit procedures performed, which is consistent with management’s assessment, we consider that the criteria and capitalization accounting policies as well as the amortization of public concession infrastructure assets referring to the gas distribution service are appropriate in the context of the financial statements taken as whole. We also evaluated the adequacy of related disclosures made by the Company in Notes 10.2 and 10.3 to the financial statements.

Other matters

Statements of value added

The individual and consolidated statements of value added (DVA) for the year ended December 31, 2022, prepared under the responsibility of the Company’s management and presented as supplementary information for IFRS purposes, were submitted to audit procedures performed jointly with the audit of the Company’s financial statements. To form our opinion, we evaluate if these statements are reconciled with the financial statements and accounting records, as applicable, and if their form and content comply with the criteria defined under Accounting Pronouncement NBC TG 09 - Statement of Value Added.

In our opinion, these statements of value added were prepared fairly, in all material respects, in accordance with the criteria defined in the referred to Accounting Pronouncement, and are consistent in relation to the individual and consolidated financial statements taken as a whole.

7

Other information accompanying the individual and consolidated financial statements and the auditor’s report

The Company’s management is responsible for such other information, which comprise the Management Report.

Our opinion on the individual and consolidated financial statements does not cover the Management Report and we do not express any form of assurance conclusion thereon.

In connection with our audit of the individual and consolidated financial statements, our responsibility is to read the Management Report and, in doing so, consider whether this report is materially inconsistent with the financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If, based on the work we have performed, we conclude that there is a material misstatement of the Management Report, we are required to report that fact. We have nothing to report in this regard.

Responsibilities of management and those charged with governance for the individual and consolidated financial statements

Management is responsible for the preparation and fair presentation of these individual and consolidated financial statements in accordance with the accounting practices adopted in Brazil and the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB), and for such internal controls determined to be necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the individual and consolidated financial statements, management is responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

Those charged with governance of the Company and its subsidiaries are those responsible for overseeing the process of preparing financial statements.

Auditor’s responsibilities for the audit of the individual and consolidated financial statements

Our objectives are to obtain reasonable assurance about whether the individual and consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the Brazilian and International Standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

8

As part of the audit conducted in accordance with the Brazilian and International Standards on Auditing, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

• Identified and assessed risks of material misstatements of the individual and consolidated financial statements, whether due to fraud or error, designed and performed audit procedures responsive to those risks, and obtained audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than the risk of not detecting one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. 

•
Obtained an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's and its subsidiaries’ internal control.

• Evaluated the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management;

• Concluded on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the individual and consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or future conditions may cause the Company to cease to continue as a going concern.Evaluated theoverallpresentation, structure and content of the financial statements, including the disclosures, and whether the individual and consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

• Obtained sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the group to express an opinion on the individual and consolidated financial statements. We are responsible for the direction, supervision and performance of the group’s audit and, consequently, for the audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements, including applicable independence requirements, and communicated with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

9

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the financial statements of the current year and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

1.3. RUSSIA-UKRAINE CONFLICT

Several countries imposed sanctions on Russia, Belarus, and certain regions of Ukraine following the outbreak of war in Ukraine in late February 2022. The geopolitical situation abruptly changed, with uncertainty about the duration of the conflict, changes in the scope of sanctions and retaliatory actions, including new laws. These new circumstances restrict the freedom of operation of Cosan Group companies in the Russian region, causing distortion and volatility in its activities. The war also contributed to increased volatility in currency markets, energy prices, raw materials and other input costs, as well as supply chain tensions and a rise in inflation in many countries.

Risks related to cybersecurity, loss of reputation, potential additional sanctions, export controls and other regulations (including restrictions on transferring funds to and from Russia) have increased. The ongoing war may continue to affect production and consumer demand. The Cosan Group evaluated the consequences of the war in its Financial Statements, mainly considering the impacts on major judgments and significant estimates, in addition to the operations that may be affected, such as:

23

Explanatory Notes to the Financial Statement

(In thousands ofReais, except when otherwise indicated)

i.	Transported volume of fertilizers;
ii.	Production of sugarcane, due to unfavorable conditions for obtaining fertilizer;
iii.	An increase in oil prices as a result of a more limited supply of Russian oil may reduce our margins and put pressure on the acquisition costs of basic inputs such as diesel oil;
iv.	Debt and third-party capital for our financing and investment activities, influenced by measures to contain inflation implemented by the Brazilian government and the Central Bank of Brazil, such as an increase in the basic interest rate;
v.	Acquisition of rail tracks byRumo: althoughRumois able to obtain rail tracks from other non-Russian suppliers, the prices charged and the deadlines required by these suppliers may be unfavorable in comparison to previous commercial conditions.

There have been no effects on the annual financial statements to date. The Cosan Group will continue to monitor the facts surrounding the conflict in order to assess potential impacts on the business and, as a result, on the financial statements.

3. ACCOUNTING POLICIES

Accounting policies are included in the explanatory notes, except for those described below:

3.1. FUNCTIONAL CURRENCY AND FOREIGN CURRENCY

The individual and consolidated financial statements are presented in Reais, which is the functional currency of the Company, its subsidiaries and joint ventures in Brazil, because it is the currency of the primary economic environment in which they operate, consume, and generate resources. The main functional currencies of the subsidiaries located outside Brazil are the US Dollar, the Euro or the Pound Sterling. Unless otherwise specified, all balances have been rounded to the nearest thousand.

Monetary assets and liabilities denominated and calculated in foreign currencies at the balance sheet date are converted into the functional currency using the current foreign exchange rate. Non-monetary assets and liabilities measured at fair value in a foreign currency are converted into the functional currency using the foreign exchange rate in effect on the date the fair value was determined. Non-monetary items measured in a foreign currency based on historical cost are converted at the foreign exchange rate on the transaction date. Foreign currency differences resulting from conversions are generally accounted for in profit or loss.

Assets and liabilities arising from international operations, including goodwill and fair value adjustments resulting from the acquisition, are converted into Reais at the balance sheet date using the foreign exchange rates in effect at the time. Income and expenses from international operations are converted into Reais using the foreign exchange rates in effect on the dates of the transactions.

Foreign currency differences are recognized and presented in other comprehensive income in equity. However, if the foreign operation is a non-wholly owned subsidiary, then the relevant proportion of the translation difference is allocated to non-controlling interests. When a foreign operation is disposed of such control, loss or significant influence is lost, the amount accumulated in the translation reserve related to that foreign operation is reclassified to financial result as part of the gain or loss on disposal.

The following table presents the foreign exchange rate, expressed in Reais for the years indicated, as informed by the Central Bank of Brazil (“BACEN”):

Currency	12/31/2022	12/31/2021
Dollar (USD)	BRL 5.22	BRL 5.58
Pound Sterling (£)	BRL 6.28	BRL 7.92
Euro (€)	BRL 5.57	BRL 6.55
Yen (¥)	BRL 0.04	BRL 0.05

 3.3. CHANGE IN THE PRESENTATION AND CLASSIFICATION OF THE AMORTIZATION EXPENSE OF THE CONCESSION RIGHT'S INTANGIBLE ASSETS

The indirect subsidiary Comgás applies the intangible asset model in accordance with ICPC 01 / IFRIC 12 and CPC 04 / IAS 38 for the accounting of natural gas distribution concession contracts. However, note that the standards do not specify the classification of the amortization of concession assets in the income statement. As a result, since the acquisition of Companhia de Gás de São Paulo – Comgás (“Comgás”) in November 2012, the Company has applied an accounting policy consistent with its understanding of the essence of the operation at the time, classifying the amortization of the asset as concession as general and administrative expenses because it is not directly attributable to the gas distribution process and thus does not contribute to the cost of sales.

Because of the advancement of the Brazilian market in the gas distribution segment and the entry of new market participants, the Company was able to reassess this policy on January 1, 2022, and voluntarily change the presentation of the classification of the amortization of the concession agreement of general and administrative expenses for costs of sales, because the Company understands that such a presentation provides more relevant information to the users of its financial statements and is more in line with the practices adopted by the market. This reclassification does not impact regulatory margins or the main indicators used by the Company.

The application of the change in accounting policy resulted in the following reclassification in the income statement in the comparative year:

	Consolidated
	12/31/2021
	Reported	Reclassified	Restated
Net operating revenue	24,907,150	—	24,907,150
Cost of goods sold

Other operating income, net	387,440	—	387,440
Operational result	(2,382,583)	555,201	(1,827,382)
Earnings before equity income
and financial revenue, net	3,956,518	—	3,956,518
Equity Income	4,719,790	—	4,719,790
Financial result, net	(2,776,285)	—	(2,776,285)
Earnings before income tax

Income tax and social contribution	450,753	—	450,753
Net income for the year	6,350,776	—	6,350,776

This reclassification was also reflected in Note 4 - Segment information.

4. SEGMENT INFORMATION

The Company's senior management (the Chief Operating Decision Maker) uses segment information to evaluate the performance of operating segments and make resource allocation decisions. Earnings before interest, taxes, depreciation, and amortization ("EBITDA") are used by the Company to evaluate the performance of its operating segments.

Reported Segments

1. Raízen: operates in (i) the production, commercialization, origination, and trading of first and second power generation, (ii) commercialization of natural gas and acting as a commercial representative regarding the sale of lubricants at fueling stations, (iii) operations related to the Shell Select convenience store business and proximity OXXO of the Nós Group, a joint venture with FEMSA Comércio. After the completion of Raízen's corporate reorganization on June 1, 2021, our senior management began to view Raízen as a single reportable segment. Consequently, our previously reported segment information for all periods presented has been restated to reflect changes in reportable segments.
2. Gas and Energy: (i) distribution of piped natural gas throughout Brazil to industrial, residential, commercial, automotive, and cogeneration customers; (ii) commercialization of electricity and natural gas; (iii) development of infrastructure projects in a regasification terminal and offshore gas pipeline; and (iv) development of thermal generation projects utilizing natural gas.
3. Moove: production and distribution of licensed Mobil lubricants in Brazil, Bolivia, Uruguay, Paraguay, Argentina, the United States, and the European market. Additionally, under the Comma brand, it manufactures and distributes products for European and Asian markets and corporate activities.
4. Logistics: logistics services for rail transport, port storage and loading of goods, primarily grains and sugar, leasing of locomotives, wagons, and other railroad equipment, as well as operation of containers.
5. Cosan Investimentos is divided into two reportable sub-segments: (i) Land: management of agricultural properties; and (ii) Other Investments: mining and logistics projects, digital platforms for logistics services, in addition to the investment in the Climate Tech Fund, a fund managed by Fifth Wall that specializes in technological innovation.

Reconciliation:

1. Corporate Cosan: This segment represents Cosan's corporate structure, which includes expenses with consulting services, personnel and various legal claims. In addition to the investment made in Vale, the Corporate segment also includes other investments.

Even though Raízen is an equity method joint venture that is not proportionally consolidated, Management continues to review segment-specific data. In the column titled "Deconsolidation of joint ventures," the reconciliation between these segments is demonstrated.

5. FINANCIAL ASSETS AND LIABILITIES

Accounting policy:

Measurement of financial assets and liabilities

The Company initially measures a financial asset at its fair value plus (in case of a financial asset that is not measured at fair value through financial result) transaction costs, with the exception of those measured at amortized cost and maintained within a business model with the goal of obtaining contractual cash flows that meet the principal and interest only criterion.

Debt financial instruments are subsequently measured at fair value through financial result, amortized cost or fair value through other comprehensive income.

The classification is based on two criteria: (i) the Company's business model for managing the assets; and (ii) whether the contractual cash flows from the instruments represent only principal and interest payments on the outstanding principal amount.

The Company started recognizing its financial assets at amortized cost for financial assets held within a business model with the objective of obtaining contractual cash flows that satisfy the "Principal and Interest" criterion. This category includes trade receivables, cash and cash equivalents, receivables from related parties, other financial assets, dividends and interest on equity receivable, and other financial assets.

Purchases or sales of financial assets that require the delivery of assets within a period established by regulation or market convention (regular trades) are recorded on the trade date, i.e., the date on which the Company enters into an agreement to buy or sell the asset.

Financial assets are derecognized when the rights to receive cash flows from these assets have expired or when the Company has transferred substantially all risks and rewards associated with ownership.

Financial liabilities are categorized based on whether they are measured at amortized cost or fair value through financial result. A financial liability is categorized as measured at fair value through financial result if it is held for trading, is a derivative, or was designated as such upon initial recognition. Financial liabilities are measured at fair value and the net result, including interest, is included in the financial result. Other financial liabilities are subsequently measured using the effective interest method at their amortized cost. Interest expense and foreign exchange gains and losses are accounted for in the financial result.

The Company derecognizes a financial liability when its contractual obligations are discharged, cancelled, or expired, or when its terms are modified and the cash flows of the modified liability are materially different, in which case a new financial liability is recognized at fair value based on the modified terms. Any gain or loss on derecognition is accounted for in the financial result.

(i) The Company’s subsidiaries seek to improve their working capital efficiency by negotiating longer payment terms with their suppliers and entering into structured payment agreements (also known as reverse factoring or drawn risk) with third-party intermediaries, such as financial institutions. On December 31, 2022,RumoandMoovehad advanced R$710,736 and R$64,099 with financial institutions, respectively, compared to R$514,716 and R$57,704 on December 31, 2021. Thecounterpartiesfor these transactions were first-rate banks, with an average rate of 14.53% p.a. (10.60% p.a. on December 31, 2021) forRumoand CDI + 2.5% p.a. (CDI + 2.5% p.a. on December 31, 2021) forMoove. The average term of these transactions, which are recorded at present value using the above rate, is approximately 109 and 102 days (90 and 107 days on December 31, 2021). The financial charges embedded in the transaction are recorded as financial revenue, totaling R$96,752 for the fiscal year ending December 31, 2022 (R$27,155 for the fiscal year ending December 31, 2021). We also have a voluntary supply chain finance ("SCF") program that allows suppliers, at their sole discretion, to take advantage of our credit rating. Subsidiaries and their suppliers agree to commercial terms for the goods and services we purchase, including prices, quantities and payment terms, regardless of whether the supplier chooses to participate in the SCF program. The subsidiaries and its suppliers agree to the commercial terms for the goods and services we purchase, including prices, quantities, and payment terms. There are no modifications to any of our payment obligations to our suppliers. Under the SCF program, neither the Company nor any of its subsidiaries provide any guarantees. When contracted, the Company and its subsidiaries pay the financial institution the full nominal value of the originating obligation on the original payment date. For the SCF program, the subsidiariesRumoand Compass have supplier advances with financial institutions totaling R$107,133 and R$72,579 on December 31, 2022 (R$62,070 and R$91,933 on December 31, 2021). The settlement flow of the balance of credits assigned by suppliers to financial agents is classified in the statement of cash flows as operating activities as this more accurately reflects the cash expenditure from the perspective of the Company's operations.

5.1. NET DEBT

The information in the table below presents a reconciliation of net debt, a non-GAAP financial measure. A non-GAAP financial measure is generally defined as one that is intended to measure financial performance but excludes or includes amounts that would not be adjusted for in the most comparable GAAP measure.

Net debt is also used to calculate certain leverage ratios. However, net debt is not a measure in accordance with the IFRS and should not be considered as a substitute for measures of debt determined in accordance with the IFRS and the Brazilian accounting standards.

5.3. MARKETABLE SECURITIES AND RESTRICTED CASH

Accounting policy:

The valuation and classification of marketable securities are based on their fair value, as determined by the financial result. Securities consist of all equity instruments with readily ascertainable fair values. The fair values of equity instruments are deemed readily determinable if the securities are listed or if a current market value or fair value can be determined even without a direct listing (for example, prices of shares in mutual funds).

Restricted cash is measured and classified at amortized cost, with an average maturity of between two and five years for government bonds, but they can be redeemed quickly and are subject to an insignificant risk of depreciation.

(i)	According to Note 1.2.6, financial investment in Vale is measured at fair value using the closing date result. Such investment was classified as non-current assets, as the Company does not intend to sell these shares in the short term, although these shares are extremely liquid and readily convertible into cash.
(ii)	The sovereign debt securities declared interest linked to the Special System of Liquidation and Custody (SistemaEspecial deLiquidaçãoeCustódia), or “SELIC”, with a yield of approximately 100% of the CDI.

5.4. LOANS, FINANCING AND DEBENTURES

Accounting policy:

Initial measurement is at fair value, net of transaction costs, and subsequent measurement is at amortized cost.

When the obligation specified in the contract is satisfied, canceled, or expires, they are deregistered. The difference between the carrying amount of a financial liability that has been extinguished or transferred to another party and the consideration paid, including any non-monetary assets transferred or liabilities assumed, is recorded as other financial revenue or expense in the income statement.

Classified as current liabilities unless there is an unconditional right to defer settlement for at least one year after the date of the balance sheet.

Initial measurement of financial guarantee contracts issued by the Company is at fair value, and if not designated at fair value in the financial result, the financial guarantee contracts are subsequently measured at the higher amount between:

1. the amount of the obligation under the contract; and
2. the amount initially recognized less, as applicable, the accumulated amortization recognized according to revenue recognition policies.

The terms and conditions of the outstanding loans are as follows:

The Company and its subsidiaries had unused bank lines of credit totaling R$3,052,287 on December 31, 2022 (R$3,648,023 on December 31, 2021). The use of these credit lines is subject to certain contractual terms.

c)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.

5.5. LEASE LIABILITIES

Accounting policy:

Upon inception or modification of a contract, the Company assesses whether the contract is or contains a lease.

The lease liability is initially measured at the present value of the lease payments that are not made on the commencement date, discounted at the interest rate implicit in the lease or, if that rate cannot be determined easily, at the Company's incremental borrowing rate. The Company's incremental borrowing rate is generally used as the discount rate.

Lease assets and liabilities are initially measured at present value. The lease payments included in calculating the lease liability are as follows:

1. fixed payments, including fixed payments in essence;
2. index or rate dependent variable lease payments, which are initially calculated using the index or rate at the start date;
3. amounts expected to be paid by the lessee under residual value guarantees; and
4. the purchase option exercise price if the lessee is reasonably certain to exercise that option, and the payment of lease termination penalties if the lease term reflects the lessee's option to terminate the lease.

To calculate the incremental borrowing rate, the Company:

1. where possible, uses the most recent third-party financing received by the individual tenant as a starting point, adjusted to reflect changes in financing terms since the third-party financing was received;
2. uses an accrual approach that begins with a credit risk-adjusted risk-free interest rate for leases held by the Company that have not had any recent third-party financing; and
3. makes specific adjustments to the lease, e.g., term, country, currency and security.

Variable lease payments that do not depend on an index or rate are recognized as expenses in the period in which the event or condition that generates these payments occurs.

The Company is exposed to potential future increases in variable lease payments based on an index or rate, which are not included in the lease liability until they become effective. When adjustments to lease payments based on an index or rate take effect, the lease liability is remeasured and adjusted against the right-of-use asset.

Lease payments are allocated between principal and finance cost. The financial cost is charged to the financial result over the lease term to generate a constant periodic interest rate on the remaining balance of the liability in each period.

Payments associated with short-term leases of equipment and vehicles, as well as all leases of low-value assets, are recognized as an expense in the income statement on a straight-line basis. A short-term lease is a lease with a term of twelve months or less. Low-value assets include IT equipment and small office furnishings.

In determining the lease term, the Company considers all facts and circumstances that create a financial incentive to exercise or not exercise the extension option. Extension options (or periods after termination options) are only included in the lease term if there is a substantial likelihood that they will be exercised (or not terminated).

For warehouse, retail store and equipment leases, the following factors are typically most relevant:

• If there are significant penalties for terminating (or not extending), the group is normally reasonably certain to extend (or not terminate).
• If leased property improvements are expected to have a significant remaining value, the Company has a good chance of extending the lease (or not terminate).
• Otherwise, the Company considers other factors, including historical lease durations and the costs and business interruption required to replace the leased asset.

Explanatory Notes to the Financial Statement

(In thousands ofReais, except when otherwise indicated)

Most extension options on office and vehicle leases were not included in the lease liability because the Company could replace the assets without significant cost or business interruption.

The subsequent valuation of the lease liability is valued using the effective interest rate method and the cost-amortization method. It is reassessed when there is a change in future lease payments resulting from a change in index or rate, if there is a change in the amounts expected to be paid under the residual value guarantee, if the Company changes its assessment, if an option will be exercised on purchase, extension, or termination, or if the revised lease payment is essentially fixed.

The lease agreements vary in length, with the final maturity occurring in December 2058. The amounts are updated annually by inflation indexes (such as IGP-M and IPCA) or may incur interest based on the TJLP or CDI, and some of the contracts have renewal or call options that were considered in determining their classification as a finance lease.

In addition to the amortization and allocation of interest and foreign exchange rate variation highlighted in the preceding tables, the following impacts on the result were recorded for lease agreements not included in the measurement of lease liabilities:

Additional Information

The subsidiaries, in full compliance with the regulations, in the measurement and remeasurement of their lease and right-of-use liabilities, discounted the present value of the future lease installments without considering the projected future inflation in the installments to be discounted.

The incremental interest rate (nominal) used by the Company and its subsidiaries was determined based on the interest rates adjusted to the Brazilian market and the terms of their contracts. Rates ranging from 10.9% to 14.8% were used, depending on the term of each contract.

In compliance with CVM Instruction Circular Letter 2/2019, in transactions in which the incremental rate is used, if the measurement were made at the present value of the expected installments plus projected future inflation, the balances of lease liabilities, right-of-use, of the financial expense and depreciation expense for the year ended December 31, 2022, are presented in the column “Circular Letter”:

	2022			2021
Accounts	Registered	Circular Letter	% Variation	Registered	Circular Letter	% Variation
Lease liabilities	(2,356,738)	(2,542,492)	8.00%	(2,121,577)	(2,287,777)	8.00%
Residual right-of-use	6,728,345	6,725,560	—	6,743,631	6,755,661	—
Financial expense	(273,058)	(289,010)	6.00%	(253,446)	(265,511)	5.00%
Depreciation expense	(328,848)	(334,245)	2.00%	(280,462)	(285,462)	2.00%

The balances recorded by the subsidiary Rumo include the Malha Central contract and the addendum for the renewal of the Malha Paulista contract, which have an identified implicit rate, so that their valuation does not generate distortions in the liabilities and in the right-of-use object of CVM’s Circular Letter. The lease liability for these agreements was R$2,065,002 as of December 31, 2022, compared to R$1,185,207 as of December 31, 2021. As of December 31, 2022, the potential PIS and COFINS credit included in liabilities is of R$6,318 (R$6,154 as of December 31, 2021).

5.6. DERIVATIVE FINANCIAL INSTRUMENTS

Accounting policy:

Initial recognition of derivatives at fair value occurs on the date a derivative contract is entered into, and derivatives are subsequently remeasured at fair value at the end of each reporting period. Whether subsequent changes in fair value are recorded depends on whether the derivative is designated as a hedging instrument and, if so, the nature of the item being hedged. The Company identifies certain derivatives as:

i.fair value hedge of recognized assets or liabilities or of a firm commitment (fair value hedge); or

ii.hedge of a particular risk associated with the cash flows of recognized assets and liabilities and highly probable forecasted transactions (cash flow hedge).

At the inception of the hedging relationship, the Company documents the economic relationship between the hedging instruments and the hedged items, including expected changes in the cash flows of the hedging instruments. The Company documents its risk management objective and strategy for hedging transactions. Changes in the fair value of any derivative instrument that do not qualify for hedge accounting are immediately registered in the income statement and included in other financial revenue (expenses).

The fair values of derivative financial instruments designated in hedging relationships are disclosed below. The total fair value of a hedging derivative is classified as a non-current asset or liability when the remaining maturity of the hedged item is greater than 12 months; it is classified as a current asset or liability when the remaining maturity of the hedged item is less than 12 months.

The Company evaluates, both at the beginning of the hedging relationship and on an ongoing basis, whether the hedging instruments are anticipated to be highly effective in offsetting changes in the fair value or cash flows of the respective attributable hedged items. The actual results of each hedge for the hedged risk fall between 60% and 140%.

The Company maintains a portfolio of energy contracts (purchase and sale) designed to meet supply and demand for energy consumption or supply. In addition, there is a portfolio of forward positions comprising contracts. There is no purchase commitment associated with this portfolio's sales contract.

Taking into account its policies and risk limits, the Company has the flexibility to manage the contracts in this portfolio in order to profit from changes in market prices. This portfolio contains contracts that may be settled net in cash or another financial instrument (for example: by entering into an offsetting contract with the counterparty; or by "unwinding a position" from the contract prior to its exercise or expiration; or shortly after purchase, selling for the purpose of generating a profit from short-term fluctuations in price or gain on resale margin).

These energy purchase and sale transactions occur on an active market and qualify as financial instruments because they are settled at net cash value and are easily convertible to cash. These contracts are treated as derivatives and are recognized in the balance sheet at fair value on the date the derivative is entered into and remeasured at fair value on the balance sheet date.

Financial assets and liabilities are offset, and the net amount is reported in the balance sheet, when there is a legal right to offset the recognized amounts and intent to settle them on a net basis, or when the asset is realized and the liability is settled simultaneously. The legal right must be enforceable in the ordinary course of business and in the event of default, insolvency, or bankruptcy of the company or the counterparty.

The estimated fair value of these derivatives is based in part on price quotations published in active markets, to the extent that such observable market data exists, and in part on valuation techniques that take into account: (i) prices established in recent purchase and sale transactions, (ii) margin of risk in the supply, and (iii) projected market price in the availability period. A fair value gain or loss is recognized at the base date whenever the fair value at initial recognition for these contracts differs from the transaction price.

Observing the market value of Vale's shares, the company determined the fair value of its equity financial assets and classified them accordingly. The equity forward was also measured and classified at fair value through financial result based on the Black & Scholes pricing model, which utilizes the stock price, volatility of the underlying stock, and interest rates as significant input parameters.

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 financial result.

There is an economic relationship between the hedged item and the hedging instrument because the terms of the interest and FX rate swap correspond to the terms of the fixed-rate loan, i.e., notional amount, term, and payment. Since the underlying risk of the interest and FX rate swap is identical to the hedged risk component, the Company has established a hedge ratio of 1:1 for its hedging relationships. The Company employs 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 in order to evaluate the effectiveness of the hedge. According to the Company's assessment, the sources of hedge ineffectiveness that are most likely to impact the hedge relationship during its term are: (i) a reduction or change in the hedged item; and (ii) a change in the Company's or the contracted swap counterparty's credit risk. The following amounts were associated with the items designated as hedging instruments:

b)Fair value options

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

The Company chose to designate protected liabilities (hedge items) to be recorded at fair value through financial result. Considering that derivative instruments are always accounted for at fair value through financial result, the accounting effects are the same as those obtained by means of the documentation of a hedge:

5.7. TRADE RECEIVABLES

Trade receivables are initially recognized at the unconditional consideration amount unless they contain significant financing components, in which case they are recognized at fair value. The Company holds trade receivables with the intention of collecting the contractual cash flows, and subsequently measuring them at amortized cost using the effective interest rate method.

For the purpose of estimating credit losses, trade receivables have been categorized according to their credit risk characteristics and days overdue. A loss allowance for anticipated credit losses is recognized as a component of selling expenses.

The expected loss rates are derived from historical credit losses incurred during the period. Historical loss rates may be modified to reflect current and forecasted information regarding macroeconomic factors that influence the ability of customers to settle receivables. The Company has determined that the implied interest rate in the agreement is the most significant factor, and as a result, it adjusts historical loss rates based on the anticipated changes to this factor.

(ii)	On December 31, 2018, an agreement for the assumption of rights and obligations was entered into between the Company and the subsidiaryCosanLubrificanteseEspecialidadesS.A. (“CLE”) and assets and liabilities related to the fuel business were transferred from the acquisition ofEssoBrasileirade Petroleum Ltd. (“Esso”) in 2008, which were not contributed to the formation ofRaízen, a fact that generated an increase in the Company’s related parties’ assets and liabilities accounts in that year and which has been changing as transactions are settled. This transfer of assets and liabilities does not impact the Company's consolidated position, nor the segment information

5.10.SECTORIAL FINANCIAL ASSETS AND LIABILITIES

Accounting policy:

The sectorial financial assets and liabilities are intended to neutralize the economic impacts on the results of the subsidiaries Comgás and Gas Brasiliano Distribuidora S.A. (“Gas Brasiliano”), due to the difference between the cost of gas and tax rates contained in the ordinances issued by the Regulatory Agency for Public Services of the State of São Paulo (“ARSESP”), and those actually contemplated in the tariff, at each tariff readjustment/revision.

These differences between the realized cost and the cost considered in the tariff adjustments generate a right when the realized cost is higher than the cost considered in the tariff, and an obligation when the costs are lower than the cost considered in the tariff. ARSESP takes into account differences in the subsequent tariff adjustment and includes them in the distributors' tariff adjustment index.

In accordance with ARSESP’s Deliberation No. 1010, any remaining balances in existing graphic accounts at the conclusion of the concession will be indemnified to distributors or returned to users 12 months prior to the conclusion of the concession period. The balance consists of (i) the previous cycle (under amortization), which represents the balance already ratified by ARSESP and included in the tariff, and (ii) the cycle being formed, which represents the differences that will be ratified by ARSESP in the next tariff readjustment.

In addition, this Deliberation addressed the balance in the current tax account, which accumulated amounts related to tax credits used by distributors, but which are essentially part of the tariff composition and must be passed on via tariff.

The subsidiaries Comgás and Gas Brasiliano recognize, as a result of the aforementioned deliberation, that there is no longer any material uncertainty that would prevent the recognition of sectorial financial assets and liabilities as amounts effectively receivable or payable. Thus, sectorial financial assets and liabilities are reflected in their financial statements.

However, for the other distribution companies, the recognition of sectorial financial assets and liabilities will only be registered after the decision of the regulatory body.

5.11.RECOGNIZED FAIR VALUE MEASUREMENTS

Accounting policy:

When the fair value of financial assets and liabilities cannot be derived from active markets, their fair value is determined by means of valuation techniques, such as the discounted cash flow model. When possible, inputs to these models are obtained from observable markets; however, when this is not possible, some judgment is required to determine fair values. In determining data such as liquidity risk, credit risk, and volatility, judgment is required. Variations in these variables may impact the reported fair value of financial instruments.

Specific valuation techniques used to value financial instruments include:

1. the use of quoted market prices;
2. for swaps we use the present value of estimated future cash flows based on observable market curves; and
3. for other financial instruments we analyze the discounted cash flow.

Level 2 includes all resulting estimates of fair value when fair values are determined based on present values and discount rates are adjusted for counterparty or own credit risk.

The Company has an established control structure regarding the measurement of fair values.

Significant unobservable inputs and valuation adjustments are reviewed by Management on a regular basis. If third-party information, such as brokerage quotes or pricing services, is used to measure fair values, Treasury evaluates evidence obtained from third parties to support the conclusion that these valuations comply with the Company's policy, including the market level.

The Board of Directors is informed of significant valuation issues. When determining the fair value of an asset or liability, the Company makes extensive use of observable market data. A fair value hierarchy categorizes fair values into different levels based on the inputs used in valuation techniques, as follows:

• Level 1: inputs represent unadjusted quoted prices for identical instruments traded in active markets.
• Level 2: inputs consist of directly or indirectly observable data (excluding Level 1 data), including quoted prices for similar financial instruments traded in active markets, quoted prices for identical or similar financial instruments traded in inactive markets, and other observable market data. The fair value of the Company's majority of investments in securities, derivative contracts, and bonds.
• Level 3: inputs for the asset or liability that are not based on market data that are observable (unobservable inputs). Due to the lack of market activity on these instruments or related observable data that can be corroborated at the measurement date, Management is required to make its own assumptions about unobservable inputs.

If the inputs used to measure the fair value of an asset or liability fall into different levels of the fair value hierarchy, then the entire fair value measurement is classified at the same level as the lowest-level entry that is significant to the entire measurement. Among the specific techniques used to value financial instruments are:

1. use of quoted market prices;
2. fair value is determined by discounting estimated future cash flows to the present. Future cash flow estimates with a variable interest rate are based on quoted swap rates, futures prices, and interbank lending rates. When pricing interest rate swaps, estimated cash flows are discounted using a yield curve constructed from similar sources and reflecting the relevant benchmark interbank rate used by market participants for this purpose. The fair value estimate is subject to a credit risk adjustment that reflects the credit risk of the Company and its counterparty; this adjustment is computed using the credit spreads derived from the current credit default swap; and
3. analysis of the discounted cash flow for other financial instruments.

(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"). On December 31, 2022, the discount rates used ranged from 11.20 to 13.75% p.a. (6.5 to 9% p.a. on December 31, 2021).

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.

a)Market risk

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

The Company manages market risks with derivatives. All of these transactions are conducted in accordance with the Risk Management Committee's guidelines. Typically, the Company employs hedge accounting to mitigate profit or loss volatility.

1. Foreign exchange risk

As of December 31, 2022 and 2021, the Company had the following net exposure to foreign exchange variation on assets and liabilities denominated in US Dollars, Euros, Yen and Pound Sterling:

	12/31/2022	12/31/2021
Cash and cash equivalents	1,138,948	3,811,598

3. Price risk

• Electricity

Electricity operations were traded on an active market and recorded at fair value through profit or loss, based on the difference between the contracted price and the market price of outstanding contracts as of the date of the balance sheet.

The following are the equity balances pertaining to our open electricity transactions:

	12/31/2022			12/31/2021
	Assets	Liabilities	Net Income	Assets	Liabilities	Net Income
Electricity trading	—	—	—	69,576	(317,699)	(248,123)

In July 2022, the subsidiary Compass Comercialização S.A. entered into an instrument for the Assignment of Electricity Purchase and Sale Agreements with WX Energy Comercializadora de Energia Ltda., an indirect subsidiary of Raízen S.A. Through this market-based transaction, the Company assigned in full all contracts with maturities after 2022.

• Natural gas

Natural gas derivative transactions were conducted with bank counterparties and recognized at fair value through profit or loss, based on the difference between the contracted price and the market price of outstanding contracts as of the date of the balance sheet.

These are our open positions in natural gas derivatives:

			Scenarios
Instrument	Risk factor	Probable	25%	50%	(25)%	(50)%
Brent derivatives – options	Price variation US$/bbl	21,744	21,878	64,345	127,602	3,508

• Shares and options

We are exposed to market risks as a result of the fluctuating prices of certain equity securities and option instruments. Our exposure to changes in the price of equity securities is primarily derived from Vale's common shares purchased on the spot market, which, as of October 31, 2022, represent 1.55% (1.57% on December 31, 2022) of the outstanding shares.

Additionally, we enter into equity derivative contracts consisting of a combination of call and put positions (collar) that limit the risk of devaluation of the value of the shares while allowing Cosan Oito to participate in the appreciation of the shares - equal to 3.31% of Vale's outstanding shares as of October 31, 2022 (3.35% on December 31, 2022). On maturity, these contracts are expected to offset declines in the fair value of these securities below the per-share hedge price, allowing us to retain a portion of the positive valuation of the per-share hedge price to the relevant price cap. Actual per-share contract hedge prices will vary based on average share prices in effect when the contracts were entered into. Actual maximum contract prices vary based on each contract’s maturity and terms, among other factors. If any of these contracts are terminated before their scheduled maturity date due to the occurrence of a contract-specified event, we will be required to repay the fair value of the guaranteed debt minus the sum of the fair values of the underlying shares and equity collar, calculated on the date of termination. Finally, exposures resulting from derivatives are reflected in the Call Spread structure, representing an additional potential of 1.6% of Vale's outstanding shares as of December 31, 2022. In this structure, the Company does not own the shares, but it does possess an instrument that enables it to acquire the additional shares through a derivative structure. The calculated values in the aforementioned structure's sensitivity analysis reflect the impacts of the intrinsic values of the options on the valuation or devaluation of the shares.

In our consolidated balance sheets, the underlying shares and equity collars are recorded at fair value, while secured debt is recorded at principal amount, net of funding costs. These funding expenses are amortized over the respective debt's term.

In addition, we face risks associated with the share prices of CSAN3 and RAIL3. A derivative with a total return swap of 77,236,212 CSAN3 and 15,781,000 RAIL3 shares was contracted.

The sensitivity analysis considers the closing price of the shares, as shown below:

Concerning item (i).c of Note 1.2.6, the combination of derivative instruments is configured as a call spread, a structure that limits the Company's exposure to share price fluctuations. On December 31, 2022, the total value of the position was R$6,391,961. Assuming a share price increase of up to 50%, the Company would experience a limited positive impact of R$1,541,654 and a limited negative impact of R$69,748 if the share price decreased by up to 50%.

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:

Other financial assets	89,238	320,193
	24,761,444	29,356,555

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:

	12/31/2022	12/31/2021
AAA	16,769,858	23,080,390
AA	3,133,455	2,239,266
A	138,478	—
BBB	—	34,397
Not rated	65,184	—
	20,106,975	25,354,053

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.

d)Capital management risk

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.

6. OTHER RECEIVABLE TAXES

Accounting Policy:

Tax assets are measured at cost and primarily consist of (i) tax effects that are recognized when the asset is sold to a third party or recovered through amortization over the remaining economic life of the asset; and (ii) tax receivables that are expected to be recovered as refunds from tax authorities or as a reduction for future tax liabilities.

(i)

On May 13, 2021, the Federal Supreme Court ("STF") concluded the judgment of Extraordinary Appeal No. 574,706 and, under the system of general repercussion, established the thesis that the Tax on the Circulation of Goods and Services (Imposto sobre Circulação de Mercadorias e Serviços) ("ICMS") does not comprise the calculation basis of PIS and COFINS, since this amount does not constitute revenue or turnover for the Company, i.e, the taxpayers have the option to exclude the ICMS-related portion of the PIS and COFINS calculation bases from the invoice.

Since the Federal Income Office (Secretaria da Receita Federal) ("SRF") granted the request on March 30, 2022 regarding the credit claim of PIS and COFINS since July 2008, the subsidiary Comgás began using the credits for the monthly PIS and COFINS payments (R$470,943 of PIS and COFINS compensated in the year), as well as for the quarterly IRPJ and CSLL payments.

Federal tax credits were used to pay the 2021 annual adjustment as well as the monthly payment of the Corporate Income Tax (Imposto de Renda Pessoa Jurídica) ("IRPJ"), the Social Contribution on Net Income (Contribuição Social sobre o Lucro Líquido) ("CSLL"), the Social Integration Program (Programa de Integração Social) ("PIS"), and the Contribution for the Financing of Social Security (Contribuição para o Financiamento da Seguridade Social) ("COFINS"), all totaling R$928,465 (R$262,843 for December 31, 2021, referring to the annual adjustment payment for 2020). Customer-assigned ICMS tax credits were also used totaling R$123,518 (R$86,555 as of December 31, 2021) for the reduction of gas invoices. 

7. INVENTORIES

Accounting policy:

Inventories are stated at the lower of cost and net realizable value (it is the estimated selling price in the normal course of business, minus the estimated completion costs and estimated costs necessary to make the sale). The cost of finished and work-in-progress goods comprises direct materials, direct labor and an appropriate proportion of variable and fixed overheads, the latter of which are allocated based on normal operating capacity. Costs are assigned to individual inventory items based on weighted average costs. 

The provision for obsolete inventories is made for risks associated with the realization and sale of obsolete inventories, and is measured at net realizable value or cost, whichever is lower.

	Consolidated

The balances are presented net of a provision of R$38,747 for obsolete inventories on December 31, 2022 (R$26,841 on December 31, 2021).

8.     INVESTMENTS IN SUBSIDIARIES AND ASSOCIATES

8.1. INVESTMENTS IN SUBSIDIARIES AND ASSOCIATES

Accounting policy:

1. Subsidiaries

Subsidiaries are all entities over which the Company has control, are fully consolidated from the date of acquisition of control and deconsolidated when control ceases to exist. 

Control is obtained when the Company is exposed or entitled to variable returns based on its involvement with the investee and has the ability to affect those returns through the power exercised in relation to the investee.

Specifically, the Company controls an investee if, and only if, it has:

• Power over the investee (i.e., existing rights that give it the current ability to direct the relevant activities of the investee);

• Exposure or right to variable returns arising from its involvement with the investee; and

• The ability to use its power over the investee to affect the value of its returns.

There is usually a presumption that a majority of voting rights results in control. To support this presumption and when the Company has less than a majority of the voting rights of an investee, we consider all relevant facts and circumstances when assessing whether it has power over an investee, including:

• The contractual agreement between the investor and other holders of voting rights;

• Rights arising from other contractual agreements; and

• The Company's voting rights and potential voting rights.

Using consistent accounting policies, subsidiaries' financial statements are prepared for the same reporting period as the parent company. Adjustments are made to the financial statements of the subsidiaries in order to conform their accounting policies to those of the Company.

On consolidation, all transactions between related parties are eliminated. Unrealized gains resulting from transactions with investees recorded using the equity method are written off against the investment in proportion to the Company's ownership interest in the investee. Unrealized losses are eliminated in the same manner, but only if no evidence of impairment exists.

2. Associates

Associates are entities over whose financial and operating policies the Company has significant influence, but neither control nor joint control.

In preparing the consolidated financial statements, intragroup balances and transactions, as well as any unrealized income or expenses arising from intragroup transactions, are written off.

In accordance with the equity method, the equity interest of associates attributable to the Company in the profit or loss for the exercise of such investments is recorded in the income statement, under “Equity in earnings”. Unrealized gains and losses arising from transactions between the Company and its investees are written off in proportion to the Company's ownership stake in these investees. Other comprehensive income of subsidiaries, associates, and joint ventures is recorded directly under "Other comprehensive income" in the Company's shareholders' equity.

Unrealized gains resulting from transactions with investments recorded using the equity method are written off in proportion to the Company's ownership interest in the investee. Unrealized losses are written off in the same manner, but only if there is no evidence of an impairment loss.

8.2. ACQUISITION OF SUBSIDIARIES

Accounting policy:

Combinations of businesses are recorded using the acquisition method. In general, the consideration transferred in an acquisition, as well as the identifiable net assets acquired and liabilities assumed, are measured at fair value. Any goodwill that develops is annually evaluated for impairment. Unless related to the issuance of debt or equity, transaction expenses are recorded as incurred in the income statement.

For each business combination, the Company measures non-controlling interests in the acquisition using one of the following methods:

1. fair value; or
2. proportional share of the acquirer's identifiable net assets, which are typically valued at fair market price. 

The transferred consideration excludes amounts related to the liquidation of preexisting relationships. Typically, these amounts are recognized in profit or loss.

Contingent consideration depends on an acquired business meeting targets within a fixed period. In order to calculate obligations at the time of acquisition and at each subsequent reporting date, projections of future performance are required. In addition, estimates are required to value the assets and liabilities acquired in business combinations. Intangible assets, such as brands, are frequently a crucial component of an acquired business because they enable us to derive greater value than would be possible otherwise.

Measurement of fair values

In measuring fair values, valuation techniques were used considering market prices for similar items, discounted cash flow, among others.

Since this is a fair value measurement, the accounting for the acquisition will be revisited if new information obtained within one year of the acquisition date regarding the facts and circumstances that existed at the acquisition date indicates adjustments to the amounts mentioned above or any additional provision that existed at the acquisition date. Management's expectation is that only the measurements of intangible assets could have some kind of impact on this evaluation.

Acquisitions in 2022

During the year ended December 31, 2022, the Company and its subsidiaries (Compass, Atlântico and Moove) completed the acquisition of investments (Commit, Sulgás, TUP, Tirreno and PetroChoice), in addition to the acquisition of control of the investees referred to as the segment “Terras” (Tellus, Janus, Gamiovapar and Duguetiapar), shown below on an individual and consolidated basis. The paid and payable consideration, as well as the fair value of the assets acquired and liabilities assumed as of the date of acquisition, are detailed below:

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 Government of the State of Rio Grande do Sul for the amount of R$945,979, net of an anticipated dividend of R$9,264. As of this date, Sulgás has been consolidated into the Company's financial statements.

Sulgás is headquartered in the city of Porto Alegre, and its primary activity is the distribution of piped natural gas from the state of Rio Grande do Sul.

Its network of distribution totals approximately 1,400 km, serving more than 78,000 customers in 41 municipalities, with a distributed volume of 1.5 million m3/day.

The acquisition price was allocated as a concession right for gas distribution in the Company's evaluation.

The fair value of intangible assets is R$2,749,893, which includes the allocation of concession rights of R$2,582,077, as determined by the existing concession agreement between Sulgás and the granting authority. The concession period is 50 years from the contracted date (April 19, 1994 to April 18, 2044). Non-controlling interest in Sulgás was measured according to the proportional share of interest in identifiable net assets.

Since the date of acquisition, Sulgás has generated revenues and net income totaling R$1,860,342 and R$152,389, respectively, according to the consolidated income statement.

Management, for the purposes of annual procedures, reassessed the business combination factors and did not identify material changes.

TUP Porto São Luís

On August 23, 2021, the Company, through its subsidiary Atlântico Participações Ltda. (“Atlântico”), entered into a binding proposal for the acquisition of 100% of Porto São Luís, a company that owns a private terminal in São Luis/MA and whose primary objective is to increase international trade by connecting port, highways, and railroads. This transaction aims to establish a future joint venture in the mining sector, in which Cosan will contribute expertise in port logistics and management.

Atlântico completed the acquisition of 100% of Porto's shares on February 11, 2022 (“Acquisition Date”), with 49% acquired on November 3, 2021 and the remainder on the Acquisition Date. With a 100% shareholding, Atlântico becomes the sole shareholder of Porto São Luís and assumes control.

The transaction resulted in an allocation of R$436,594 in intangible assets in Licenses and Authorizations and a goodwill of R$621, representing the anticipated future economic benefit of synergies resulting from the acquisition. Goodwill is not expected to be deductible for income tax purposes.

Since the acquisition date, Porto has not contributed to the consolidated information with revenues and has contributed with a loss of R$1,440.

PetroChoice

On May 23, 2022, the subsidiary Millennium Moove Corp acquired 100% of Stryker Intermediate Holdings and its operating subsidiaries ("PetroChoice"), a Delaware, U.S.A.-based limited liability company and owner of all outstanding shares of the acquired capital stock.

The entities specialize in comprehensive solutions for lubrication and contamination control, serving a wide range of needs and industries. The acquisition is part of Moove's strategic expansion plan, which aims to foster synergies in automotive and industrial products through technology and manufacturing, distribution and cross-selling opportunities with other regions already active, replicating the group's management, strategy and sales model.

PetroChoice's consolidated financial statements were prepared in accordance with the Generally Accepted Accounting Principles in the United States of America (“US GAAP”) issued by the Financial Accounting Standards Board (“FASB”). In these financial statements, differences in the opening balance between these policies and accounting standards adopted in Brazil and in the IFRSs have been adjusted for equity accounting and consolidation. The Company identified adjustments to the goodwill and lease accounts during the evaluation.

The Company recorded inventory, fixed assets and intangible assets at fair value of US$404,941 thousand (R$1,942,624). A goodwill value of US$83,421 thousand (R$400,196) was determined, which represents the future economic benefit anticipated from the acquisition's synergies.

Commit

On July 11, 2022, Compass Gás e Energia S.A. concluded the acquisition of a 51% stake in Petrobras Gás S.A. (“Gaspetro”), for R$2,097,758, paid in a single installment. Of this amount, R$468,070 refers to the acquisition of 49% of Sulgás, which is not considered a staged business combination because the Company already controlled this entity.

With the acquisition's completion, the subsidiary assumed control of the acquiree. With the acquisition, the subsidiary strengthens its commitment to act and invest in the natural gas distribution segment, thereby helping to ensure energy security, which is essential for economic growth and increased competitiveness in the regions in which it operates. Mitsui Gás e Energia do Brasil Ltda. ("Mitsui") owns the non-controlling interest of 49% of the common shares, which is measured by the proportional share of interest in identifiable net assets and recorded in the subsidiary's equity.

For each of Commit's invested and controlled distribution companies, the fair value estimate of concessions rights was computed using a regulatory weighted average cost of capital, concession term, regulatory margin, and estimated volumes.

The net acquisition price of the acquired companies was R$1,007,634, in five annual installments of R$201,526 adjusted by the SELIC. The first installment, totaling R$202,861, was paid on October 20, 2022, of which R$1,334 was adjusted by the SELIC.

The Company, through independent consultants, assessed the fair value of all assets acquired and liabilities assumed in the opening balance sheet. Based on this assessment, no differences were identified between the fair value and the book value.

On the acquisition date, the shareholders' equity interest of the acquired companies was R$7,542,815, and their share capital was composed by: (i) Cosan, Nova Gaia Brasil Participações Ltda. and Terraviva Brasil Participações Ltda. for Tellus, Gamiovapar and Duguetiapar; and (ii) Cosan, Helios Brasil Participações Ltda. and Iris Brasil Participações Ltda. for Janus.

a)Bargain purchase gain

This business combination resulted in gain on a bargain purchase because the fair value of the assets acquired and the liabilities assumed exceeded the total fair value of the consideration paid. The fair values of the acquired assets were mainly impacted by the appreciation of agricultural properties between the base date of negotiation and the closing of the acquisition.

The Company also recognized the amount as a gain and recorded it under “other operating income, net” in the income statement for the year and was included in the Cosan Investiments segment. The effects of this gain are shown as follows:

	Janus	Tellus	Gamiovapar	Duguetiapar	Total
Shareholders’ equity	4,976,443	3,229,044	622,306	95,228	8,923,021

(In thousands ofReais, except when otherwise indicated)

The Company added the amount to its income tax and social contribution tax base. However, it did not generate a balance of tax payable since there was an accumulated balance of tax losses and a negative basis for CSLL in the current year that absorbed this gain.

Since the date of acquisition, the acquired companies have contributed R$576,851 in revenue and R$18,462 in net income to the Company.

(i) The Board of Directors approved, on December 23 and 28, 2022, the execution of an investment agreement and other covenants signed with Banco Bradesco BBI S.A. (“Bradesco”) and Itaú Unibanco S.A (“Itaú”) regulating the general terms and conditions for the entry of financial institutions as minority shareholders in the shareholding structure of the subsidiaries Cosan Dez and Cosan Nove respectively. With the completion of the transaction, the financial institutions became holders of all preferred shares issued by Cosan Dez and Cosan Nove and Cosan remained the holder of 100% of the common shares issued by the subsidiaries. With the result of the operation, Cosan now holds, directly and indirectly, 67.58% of the total share capital of Compass and 33.63% of the share capital of Raízen. It should be noted that the rights and obligations of Cosan and the financial institutions, as shareholders of Cosan Dez and Cosan Nove, were disciplined by means of a shareholders and investment agreement entered between the parties.

Explanatory Notes to the Financial Statement

(In thousands ofReais, except when otherwise indicated)

The Company has a call option for all preferred shares acquired by minority shareholders, which may be exercised under the following conditions:

i. Bradesco: in the period of the 3rd year and the 10th year counted from the signing of both transactions or at any time, in the event of (a) a material adverse effect; or (b) non-compliance with the lock-up or the preemptive right.

ii. Itaú: in the period of the 3rd year and the 10th year counted from the signature or up to the 10th year counted from the signature in case of (a) alteration of the current legislation that imposes taxation on the dividends distributed to the preferred shares; (b) any materially false statement or guarantee provided by Itaú; or (c) noncompliance with foreseen material obligations, provided that it is not remedied within a period of 30 days.

The measurement of the fair value of these instruments is based on unobservable data, since the purchase price, if incurred by the Company, is calculated on the updated value of the shareholder's investment minus the updated net income received. Minority shareholders do not hold the put option, and the equity risk of the minority shareholders' investment depends on whether or not the parent company exercises its call option.

9. INVESTMENT IN JOINT VENTURE

Accounting policy:

A joint venture is an agreement whereby the parties that have joint control of the agreement have rights to the net assets of the agreement.

The Company, through its subsidiary Cosan Nove, has an investment in a joint venture shown in the balance sheet as the share of net assets under the equity method of accounting, less any impairment losses. If applicable, adjustments are made to align any different accounting policies that may exist. The Company’s share of the results and shareholder’s equity of the joint venture is included in the income statement, comprehensive income statement and shareholder’s equity, respectively. Unrealized gains and losses resulting from transactions between the Company and its joint venture are eliminated to the extent of the Company’s investment in the joint venture, except where unrealized losses provide evidence of an impairment of the transferred asset. Goodwill arising from the acquisition of joint venture is included as part of the Company’s investment in the joint venture and, when necessary, the entire book value of the investment (including goodwill) is tested for impairment in accordance with CPC 01/IAS 36 Impairment of Assets as a single asset by comparing its recoverable amount (whichever is higher between the value in use and fair value less costs of disposal) with its book value.

The investment in joint venture is considered as non-current assets and are shown at cost less any impairment losses.

When an investment in a joint venture is classified as held for sale, it is accounted for in accordance with CPC 31/IFRS 5 Non-current Assets Held for Sale and Discontinued Operations.

Changes in investment in joint venture were as follows:

10. FIXED ASSETS, INTANGIBLE ASSETS AND GOODWILL, CONTRACT ASSETS, RIGHT-OF-USE AND INVESTMENT PROPERTIES

Accounting policy:

Reduction to recoverable value

The recoverable amount is determined through value in use calculations, using the discounted cash flow determined by Management based on budgets that take into account the assumptions related to each business, using information available in the market and past performance. Discounted cash flows were prepared over a ten-year period and carried forward in perpetuity without taking into account an actual growth rate. Management understands the use of periods greater than five years in the preparation of discounted cash flows is appropriate for the purpose of calculating the recoverable amount, because it reflects the estimated time of use of the asset and of the business groups.

The Company reviews impairment indicators for intangible assets with defined useful lives and fixed assets on an annual basis. In addition, goodwill and intangible assets with an indefinite useful life are subjected to an impairment test. An impairment occurs when the carrying amount of an asset or cash-generating unit exceeds its recoverable amount, which is the greater of its fair value less costs to sell and its value in use.

The assumptions used in discounted cash flow projections - estimates of future business performance, cash generation, long-term growth, and discount rates - are utilized in our assessment of impairment of assets as of the date of the balance sheet. No plausible change to a central premise would be harmful. The primary assumptions used to determine the recoverable value of the various cash-generating units to which goodwill is allocated are described in the following section.

92

10.1.              FIXED ASSETS

Accounting policy:

Identification and evaluation

Cost, less accumulated depreciation and any accumulated impairment losses, is used to value fixed assets.

Subsequent expenditures are only capitalized when it is probable that the associated future economic benefits will accrue to the company. Ongoing repairs and maintenance expenses are recorded as they are incurred.

Depreciated from the date of availability for use or, for constructed assets, from the date of completion and readiness for use.

Unless it is capitalized as part of the cost of another asset, depreciation is calculated on the book value of fixed assets less estimated residual values using the straight-line method over its estimated useful life and recognized in profit or loss. Land is not depreciated.

Methods of depreciation, such as useful lives and residual values, are reviewed at the end of each fiscal year or when there is a significant change without an expected consumption pattern, such as a relevant incident or technical obsolescence. If applicable, any adjustments are recorded as changes to accounting estimates.

Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets, as follows:

Buildings and improvements	4% - 5%
Machines, equipment and installations	8% - 11%
Furniture and utensils	10% - 15%
Wagons	2.9% - 6%
Locomotives	3.3% - 8%
Permanent railways	3% - 4%
IT equipment	20%
Others	10% - 20%

b)Capitalization of borrowing costs

The subsidiary Rumo’s capitalized borrowing costs were R$86,614 on December 31, 2022 (R$70,609 on December 31, 2021), using an average rate of 13.25% (11.81% on December 31, 2021), while Compass capitalized R$62,365 at an average rate of 6.27% p.a. (R$7,512 and 2.78% pa in the year ended December 31, 2021).

10.2.              INTANGIBLE ASSETS AND GOODWILL

Accounting policy:

a)Goodwill

Goodwill is initially recognized in accordance with the accounting policy for business combinations (see Note 8.2). Its value is determined by deducting accumulated impairment losses from its cost.

Goodwill acquired in a business combination is assigned to the Company's CGUs or groups of CGUs that are anticipated to benefit from the synergies created by the business combination.

b)Other intangible assets

Other acquired intangible assets with a short useful life are measured at cost, less accumulated amortization and any accumulated impairment losses.

c)Customer relationships

Costs incurred in developing gas systems for new customers (including pipelines, valves, and other equipment) are considered intangible assets and amortized over the contract's term.

The costs associated with the customer portfolio and right-of-use and operation contracts are considered as intangible assets and amortized over the contract's term.

95

Explanatory Notes to the Financial Statement

(In thousands ofReais, except when otherwise indicated)

d)Concession rights

Some of the Cosan Group's subsidiaries hold public concession contracts for the gas distribution service, in which the Granting Authority controls the services provided and the price, in addition to retaining a significant stake in the infrastructure at the conclusion of the concession. During the term of these concession contracts, the right to charge users for gas delivery is granted. Consequently, the subsidiaries acknowledge this right as an intangible asset.

Acquired or built assets underlying the necessary concession for gas distribution are amortized over the period during which the future economic benefits of the asset are anticipated to revert to the subsidiaries, or the final term of the concession, whichever comes first. This period reflects the economic useful life of each of the concession's underlying assets. This economic useful life is also used by regulatory bodies to establish the basis for calculating the tariff applicable to the provision of concession-eligible services.

In accordance with the requirements of the regulatory body, the straight-line method is used to recognize amortization, which reflects the expected pattern for the use of future economic benefits over the useful life of the assets comprising the infrastructure.

The amortization of assets ceases when the respective asset is fully utilized or written off, whichever occurs first, at which point it is removed from the tariff calculation basis for the provision of concession services.

e)Rumo’s concession rights

Rumo's concession rights resulting from the business combination with Rumo Malha Norte were fully allocated to the Rumo Malha Norte concession and amortized in a straight-line basis.

f)Port authorization and license

The subsidiary TUP possesses a license that authorizes the installation of a private port terminal, with no expiration date as long as the property is used for this purpose. Given this entity's core activity, the Company allocated a significant portion of the purchase price to this authorization, which is classified as an intangible asset with an indefinite useful life.

g)Subsequent expenses

Subsequent expenses are capitalized only if they increase the future economic benefits embodied in the particular asset to which they pertain. All other expenses are recorded in profit or loss as incurred.

h)Amortization

Except for goodwill and intangible assets with indefinite useful life, intangible assets are amortized using a straight-line method over their estimated useful lives, beginning on the date they are acquired or made available for use.

At each reporting date, the depreciation methods, useful lives, and residual values are evaluated and adjusted as necessary.

b)Goodwill paid for expected future profitability and intangibles with an indefinite useful life 

Below we show the carrying amount of goodwill and intangible assets with indefinite useful lives allocated to each of the cash generating units:

	12/31/2022			12/31/2021
	Goodwill	Brands and patents	Licenses and authorizations	Goodwill	Brands and patents
UGC Moove	1,296,266	154,722	—	916,742	57,439

	1,460,072	154,722	436,594	1,132,817	57,439

In general, future cash flow projections for the Company assume growth rates of 2.7% (3% in 2021), which are neither higher nor greater than the long-term average growth rates for the sector and country in particular.

To determine the present value of cash flows, a pre-tax discount rate is utilized. Before taxes and in nominal terms, discount rates ranged between 10.1% and 24.8% (between 8.3% and 12.2% in 2022).

The main assumptions for the first part of the financial model consider inflation and GDP by region where the UGC is located, plus the Cosan Group's strategies and market opportunities. For the remaining years of the model, the main assumptions relate to inflation and market expansion. The discount rate used is the weighted average cost of capital, or “WACC”, for which the main assumptions are: risk-free rate (return rate of an investment without risk of loss), market risk premium (excess return earned by an investment in the stock market at a risk-free rate) and inflation. Most assumptions are obtained from external sources of information.

Future cash flows were constructed considering the following factors: (i) EBITDA for the cash-generating unit, adjusted for other relevant operating cash items and recurring capital expenditures; (ii) the Cosan Group discount rate (WACC) before taxes; and (iii) a growth rate calculated using the inflation index by region.

The annual impairment test utilized the following assumptions:

Premises	% Yearly
Risk-free rate (T-Note 10y)	3.50%
Inflation (BR)	3.87%
Inflation (US)	2.30%
Inflation (UK)	2.56%
Country risk premium (BR)	5.19%
Country risk premium (UK)	1.03%
Country risk premium (ARG)	20.71%
Market risk premium	5.11%
Tax rate (BR)	34.00%
Tax rate (UK)	19.00%
Tax rate (ARG)	30.00%

Explanatory Notes to the Financial Statement

Determining the recoverability of assets depends on certain key assumptions that are influenced by the market, technological, and economic conditions prevailing at the time this recovery is tested; therefore, it is not possible to predict whether there will be future losses due to a reduction in recoverability and, if so, whether they would be material.

During the year ended December 31, 2022, the Company did not identify any additional indicators of impairment, so no impairment test was required for tangible and intangible assets with defined useful lives. Consequently, no impairment expense was recorded for goodwill and assets with indefinite and definite useful lives on December 31, 2022 and 2021.

10.3.             CONTRACT ASSET

Accounting policy

Contract assets are measured based on their acquisition cost, which includes capitalized borrowing costs. The depreciable amounts in the concession contract are transferred to intangible assets when the assets are put into operation. The indirect affiliate Comgás reassesses the useful life, and whenever this assessment reveals that the amortization period will exceed the term of the concession agreement, a portion of the asset is converted into a financial asset because it represents a receivable from the granting authority. This classification follows IFRIC 12 - Concession Agreements.

a)Investment commitments (unaudited)

The indirect subsidiary Comgás assumed commitments in its concession contract for investments (expansion, improvements, and maintenance) to be carried out during the estimated concession period until 2049. In addition to investments in administrative support, the investment values for expansion projects and operational support exceed R$2,000,000, with an expected disbursement of approximately R$3,000,000.

Considering that the concession contract provides for incentive regulation, defining an efficient business plan at each five-year cycle in light of a capital return rate defined at the time to ensure that the concessionaire is able to obtain adequate remuneration for its investments, Comgás will propose a binding regulatory plan for each tariff revision, taking into account the reality at the time and the rate of return on capital defined by the regulator.

The other distributors do not have investment commitments to be made during the concession period.

b)Capitalization of borrowing costs

During the year ended December 31, 2022, the indirect subsidiary Comgás capitalized R$70,884 at a weighted average annual rate of 12.06%p.a. (compared to R$33,829 and 8.45% in the year ended December 31, 2021).

During the year ending December 31, 2022, the indirect subsidiary Sulgás capitalized R$217 at a weighted average rate of 4.10%p.a.

10.4. RIGHT-OF-USE

Accounting policy:

The right-of-use asset is initially measured at cost, which includes the initial measurement value of the lease liability, adjusted for any lease payments made up to the commencement date, any initial direct costs incurred by the lessee, and an estimate of the costs to be incurred by the lessee in dismantling and removing the underlying asset, restoring the site where it is located, or restoring the underlying asset to the condition required by the terms and conditions of the lease.

The right-of-use asset is then depreciated on a straight-line basis from the date of commencement until the end of the lease term, unless the lease transfers ownership of the underlying asset to the lessee at the end of the lease term, or if the cost of the lease right-of-use asset reflects the likelihood that the lessee will exercise the purchase option. In this instance, the right-of-use asset will be depreciated over the useful life of the underlying asset, which is determined in the same manner as property, plant, and equipment. In addition, the right-of-use asset is periodically adjusted for certain remeasurements of the lease liability and impairment losses, if any.

The subsidiary Rumo evaluated its railway concessions within the scope of interpretation IFRIC 12 / CPC 01 Concession Contracts and, since it did not meet the terms of this interpretation, recorded its concession contracts as a right-of-use.

10.5.INVESTMENT PROPERTY AND HELD FOR SALE

Accounting policy:

Investment properties are initially value at cost, including transaction costs. Upon initial recognition, investment properties are measured at fair value, which reflects market conditions at the date of the balance sheet, with changes recorded in the income statement. Revenue from the sale of agricultural properties is not recognized in income until I the sale is complete, (ii) the Company determines that payment by the buyer is probable, (iii) the revenue can be reliably measured, and (iv) the Company has transferred all risks associated with the property to the buyer and no longer has any involvement with the property. The gains from the sale of agricultural properties are reported as net income on the income statement, while the costs are reported as cost of properties sold.

The fair value of agricultural properties was determined using the direct comparative method of market data applied to transactions involving comparable properties (type, location, and quality of property) and, to a lesser extent, using sales quotes for potential transactions involving comparable assets (level 3). In accordance with the standards issued by the Brazilian Association of Technical Standards (Associação Brasileira de Normas Técnicas – “ABNT”), 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. On December 31, 2022, discount rates range between 11.20%p.a. and 13.75%p.a. (6.5%p.a. and 9%p.a. on December 31, 2021).

The portfolio is evaluated annually by external specialists and periodically by internal professionals who are technically qualified to conduct this type of evaluation.

The Company classifies noncurrent assets (primarily agricultural investment properties from the Cosan Investimentos segment) and divestment groups as held for sale if their carrying amounts are recovered primarily through a sale transaction as opposed to continued use. Noncurrent assets and divestment groups classified as held for sale (with the exception of investment properties measured at fair value) are recorded at the lower of carrying amount and fair value less selling costs. Costs to sell are the incremental costs directly attributable to the sale of an asset (divestment group), excluding financial and income tax expenses.

The criteria for classification as held for sale are satisfied only when the sale is highly probable and the asset or group to be disposed of is immediately available for sale in its current state. The actions required to close the sale must indicate that it is unlikely that significant changes will be made or that the decision to sell will be reversed. The management must be committed to the asset sale plan, and the sale must be completed within one year of the classification date.

Investment properties held for sale continue to be measured at fair value. In the balance sheet, assets and liabilities classified as held for sale are presented separately.

Commitments with supply contracts

Taking into account the current gas supply contracts, the subsidiaries have total financial commitments with a present value of R$ 12,964,677, which includes the minimum established in the contract for both commodities and transport and expires in December 2027.

12. CONCESSIONS PAYABLE AND COMMITMENTS

Accounting policy:

This account contains the balance of lease payments at issue in disputes with the granting authority. Upon transfer from the "lease liabilities" account, the initial registration is completed at the value of the installment at maturity. These values are then adjusted using the SELIC rate.

In this account, balances are maintained in installments with the Granting Authority. The initial registration is for the balance owed following the resolution of the dispute. These values are then adjusted using the SELIC rate.

Balances payable for granted concession rights ("Concessions and Grants"), initially recorded as a counterpart to intangible assets, are also recorded in this account (Note 10.2). The following measurement is performed at the effective rate.

a)Disputed lease and concession:

On July 21, 2020, Rumo filed with the National Land Transport Agency (Agência Nacional de Transportes Terrestres – “ANTT”) a request to participate in a third-party re-bidding process for the Concession Agreement entered into between Malha Oeste and the Federal Government, through the Ministry of Transport ("Rebidding Process"), in accordance with Law No. 13,448 of June 5, 2017 and Decree No. 9,957 of August 8, 2019. An amendment to the concession agreement was signed, and as a result, the economic and financial rebalancing action filed by Rumo Malha Oeste against the Union, which had a decision of origin from the lower court and was awaiting a ruling from the Federal Regional Court, was suspended by joint decision of the parties.

The total amount of judicial deposits related to the aforementioned cases is R$24,125 (R$21,119 on December 31, 2021).

c)Investment commitments

Typically, the sub-concession contracts to which the subsidiary Rumo, through its subsidiaries, is a party include commitments to make investments with particular characteristics during the duration of the contract. We can highlight:

(i)

The addendum for the renewal of the MalhaPaulista concession, which stipulates the execution of a series of investment projects to increase capacity and reduce urban conflicts over the duration of the concession, is estimated by the agency to cost R$6,100,000 (updated until December 2017). Of this amount, approximately R$3,000,000 represents obligations, of which 22% had been physically executed as of the date of the balance sheet.

(ii)

The Malha Central sub-concession agreement stipulates fixed-term investments (one to three years from the date of the agreement's signing), estimated by ANTT to be worth R$645,573. The physical execution of the contract's projects reached 76% on December 31, 2022 (65% on December 31, 2021).

Due to the sale of the stake in EPSA (Note 1.2.8), the concession agreement for which it is responsible is no longer included in the Company's consolidated financial statements for the year ended December 31, 2022.

14. INCOME TAX AND SOCIAL CONTRIBUTION

Accounting policy

The total rate of income tax and social contribution is 34%. Current tax and deferred tax are recognized in profit or loss, with the exception of certain transactions which are directly recognized in shareholder’s equity or other comprehensive income.

a)Current tax

It is the expected tax payable or receivable on taxable profit or loss for the year, using tax rates enacted or substantively enacted as of the date of the balance sheet, as well as any adjustments to tax payable in respect of prior years.

b)Deferred tax

Deferred tax is recognized as temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation and tax loss.

The measurement of deferred tax reflects how the Company expects, at the end of the reporting period, to realize or settle the carrying value of its assets and liabilities. Deferred tax is measured at the rates anticipated to be applied to temporary differences upon their reversal, using rates enacted or substantively enacted as of the date of the balance sheet.

If there is a legally enforceable right to offset current tax assets and liabilities, and if they relate to taxes imposed by the same tax authority on the same taxable entity, deferred tax assets and liabilities are offset.

c)Tax exposure

In calculating the amount of current and deferred tax, the Company considers the impact of uncertain tax positions and the possibility of additional taxes and interest being owed. This evaluation is based on estimates and hypotheses and may involve a series of future event judgments. New information may become available, causing the Company to change its opinion regarding the sufficiency of existing tax liabilities; such changes in tax obligations will have an impact on tax expenses in the period in which the determination is made.

d)Recoverability of deferred income tax and social contribution

When evaluating the recoverability of deferred taxes, Management takes future taxable income projections and changes in temporary differences into account. The recoverability of the deferred tax asset in the parent company does not depend on taxable income projections. When it is unlikely that a portion or all of the tax liability will be realized, the tax asset is reversed. No deadline exists for the utilization of tax losses and negative bases, but the utilization of these accumulated losses from prior years is limited to 30% of annual taxable income.

The Company and its subsidiaries adhere to both the letter and spirit of the tax laws and regulations of the countries in which they conduct business, being committed to good tax practices. They are also committed to the practice of transfer pricing that respects the principles of full competition and the rules defined by the tax legislation of the jurisdictions in which they operate, with transparency of operations, business ethics, and no use of practices that result in an artificial reduction in taxation.

(ii)	During the year ended December 31, 2022, the indirect subsidiary Comgásrecognized an extemporaneous credit in the amount of R$ 272,593 (R$240,251 principal and R$32,342 interest), used to offset against IRPJ, CSLL, PIS and COFINS payable overdue in the year, related to overpayments of IRPJ and CSLL, due to the non-taxation of the benefit of reducing the ICMS tax base in the State ofSãoPaulo from 12% to 15% pursuant to art. 8 of Annex II of the ICMS Regulation, approved by State Decree No. 45,900 (“RICMS/SP”), as amended by State Decree No. 62,399/2016, in the years 2017, 2018 and 2019, when this benefit was not computed in the calculation of the IRPJ and CSLL owed by the Company. The Company recognized these credits based on its best understanding of the subject, which was supported by the opinion of its external legal counsel, which considered all applicable case law. In addition, the Company considered all current accounting rules, which, when analyzed collectively, did not indicate any other accounting effect to be recognized.
(iii)	Beginning January 1, 2021, the subsidiaryComgáschanged its tax procedure by excluding the benefit of reduction in the ICMS calculation base, granted by the State ofSãoPaulo, directly from the calculation of IRPJ and CSLL for the current year.
(iv)	Reversal of deferred income tax and social contribution obligations on the amortization of capital gains due to the gain recorded in the formation ofRaízen.
(v)	During the year ended December 31, 2021, the Company reversed deferred IRPJ and CSLL totaling R$284,738 on put interest option in the investment operation involvingCosanInvestimentoseParticipaçõesS.A. and the banks which are preferred shareholders, due to the liquidation of the put option.
(vi)	Considering the effects ofSTF’sjudgement on case RE No. 1,063,187, dated September 24, 2021, it was determined that certain financial effects related to a recovery in the event of a refund claim for excessive taxes should not form the basis of the Company's taxable income and the taxable income of its subsidiaries The total amount of credits appropriated in 2022 was of R$22,103.

Explanatory Notes to the Financial Statement

(In thousands of Reais, except when otherwise indicated)

The Company determined the period for offsetting its deferred tax assets on tax losses, social contribution negative basis and temporary differences based on the projection of its taxable income and long-term strategic planning, with the following realization expected on December 31, 2022: 

	Parent company	Consolidated
within 1 year	74,406	273,887
1 to 2 years	73,342	216,750
2 to 3 years	468,680	644,339
3 to 4 years	409,914	623,869
4 to 5 years	708,740	982,785

8 to 10 years	—	612,863
Total	1,857,620	4,474,124

Rumo Malha Sul and Rumo Malha Oeste have tax losses and temporary differences in the amount of R$1,463,526 and R$825,770 respectively that, under current conditions, do not meet the requirements for recognition of the deferred income tax and social contribution due to the lack of predictability of future generation of taxable income.

15.  PROVISION FOR LAWSUITS AND JUDICIAL DEPOSITS

Accounting policy:

They are recognized as other expenses when the Company has a present or constructive obligation as a result of previous events, it is expected that an outflow of resources will be required to settle the obligation, and the amount can be estimated with reasonable certainty.

The chance of loss evaluation is comprised of existing facts, the hierarchy of laws, case law, the most recent court decisions, the legal system's relevance, and the opinion of outside counsel. Provisions are examined and altered for conditions, such as the expiration of the statute of limitations, the conclusion of tax audits, or the identification of additional exposures based on new matters or judicial decisions.

Provisions for lawsuits stemming from business combinations are valued at fair market value.

As of December 31, 2022 and December 31, 2021, the Corporation had contingent liabilities and judicial deposits pertaining to:

(i)Offset of FINSOCIAL with federal taxes, based on a September 2003 final and non-appealable court ruling in the case records where the constitutionality of FINSOCIAL was discussed. Compensation of taxes remains a topic of administrative discussion.

(ii)Amount provisioned as INSS, the majority of which is comprised of amounts related to social security contributions levied on billing in accordance with article 22-A of Law 8.212/91, the constitutionality of which is being litigated. The amounts are deposited with the court. The leading case, RE 611.601 (item 281), is being decided by the Federal Supreme Court.

(iii)ICMS required by the State of São Paulo as a result of disallowances of diesel oil credits utilized in agro-industrial production. The stay of execution was overturned, as were the subsequent appeals.

Several civil, environmental, and regulatory judicial and administrative proceedings involving the Company and its subsidiaries present a potential for loss. The majority of civil litigation consists of contractual and extracontractual claims for damages. In the environmental realm, the processes involve commitment terms, civil investigations, and public civil actions. Regarding cases involving substantial sums, the following are the most pertinent:

Explanatory Notes to the Financial Statement

(In thousands ofReais, except when otherwise indicated)

We did not identify any effects of IFRIC 23 / ICPC 22 - Uncertainty about Treatment of Income Taxes that could have an impact on the accounting policies of the Company and its subsidiaries or these financial statements. No provision was recorded in accordance with CPC 25/IAS 37 because the Company and its subsidiaries' legal counsel determined the probability of loss to be possible, with a remote loss bias. 

Labor:

The indirect subsidiary Rumo Malha Paulista is currently a party to a pending Labor Court Public Civil Action. This lawsuit originated from an inspection conducted on the company MS Teixeira, which was subcontracted by Prumo Engenharia Ltda. ("Prumo Engenharia"), which, in turn, was subcontracted by Rumo. According to the inspection, MS Teixeira employees worked under degrading and slave-like conditions. Prumo Engenharia assumed full liability for the condition of these employees, including labor and contractual liabilities, as well as all damages resulting from the alleged subcontractors' working conditions. With the sanction by the then-Ministry of Labor and Employment, Prumo Engenharia rescinded the employment contracts of these workers, with the caveat that Rumo did not participate in these acts. In addition, a criminal investigation against Rumo was initiated and closed. Notwithstanding the above, the Public Ministry of Labor filed a public civil action (Ação Civil Pública - ACP) against Malha Paulista, without involving Prumo in the dispute, requesting the payment of compensation for collective pain and suffering in the order of R$100,000 (among other commitments), which was held partially valid, condemning the subsidiary in obligations to act and to refrain, as well as collective moral damages in the amount of R$15,000. Rumo entered into an agreement with the Public Ministry of Labor in which it agreed to comply with several obligations pertaining to working conditions and pay a total of R$20,000 in compensation to various social entities. Superior Labor Court upheld the validity of the agreement. After approval, the Attorney General's Office filed an appeal challenging only the allocation of the indemnity, arguing that the indemnity should have been allocated to the Worker Support Fund (Fundo de Amparo ao Trabalhador – FAT). The appeal awaits a decision. The outcome of the appeal will have no effect on Rumo. We consider the risk of provision as remote.

17. EARNINGS PER SHARE

Accounting policy:

a)Basic earnings per share

Basic earnings per share is calculated by dividing:

1. the profit attributable to the company's owners, excluding equity servicing costs other than common stock; and
2. the weighted average number of outstanding common shares during the year, adjusted for bonuses paid with common shares issued during the year and, if applicable, excluding treasury shares.

b)Diluted earnings per share

Diluted earnings per share adjusts the values used in determining basic earnings per share to account for:

1. the after-tax effect on interest income and other financing costs related to potentially dilutive common stock;
2. the weighted average number of additional shares of common stock that would be outstanding if all potentially dilutive shares of common stock were converted; and
3. the weighted average number of additional shares of common stock that would be outstanding if all potentially dilutive shares of common stock were converted.

Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during the year. Earnings per share after potentially dilutive instruments are computed by adjusting earnings and the number of shares for the impact of potentially dilutive instruments.

Earnings per share
Basic	R$0.6292	R$3.3378
Diluted	R$0.6264	R$3.3264

Diluting instruments

There are two categories of potential dilutive effects for the Company and its subsidiaries: stock options and put options. For stock options, 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 options in subsidiaries. It is assumed that the put option was converted into common stock, and the profit attributable to the parent's shareholders is adjusted accordingly. 

Anti dilution instruments

During the period ending December 31, 2022, 61,540,876 shares related to the Company's share repurchase program were considered on the calculation of earnings per share but do not caused impact on the calculation because they increased earnings per share.

18. NET OPERATING INCOME

Accounting policy:

The Company recognizes revenue primarily from the following sources:

1. Sale of products

The Company records sales revenue upon customer delivery. Delivery is regarded as occurring when the customer accepts the goods and ownership risks and benefits are transferred. This is the point at which revenue is recognized if revenue and costs can be reliably measured, receipt of consideration is probable, and there is no ongoing management involvement with the products.

The subsidiary Moove is responsible for the production and distribution of lubricants, including Mobil and Comma brands. Products are sold under identified contracts with individual or multiple customers, as a bundle of goods or services.

124

Explanatory Notes to the Financial Statement

(In thousands ofReais, except when otherwise indicated)

Some lubricant sales contracts are not available for purchase outside of a service package. However, contracts clearly distinguish between goods and services. This type of sale represents two separate performance obligations; consequently, revenue will be recognized for each performance obligation upon transfer of control of the respective goods and services to the customer. On the basis of the standalone sale price, the transaction price is allocated to various performance obligations in which revenues are separately identified, measured, and recorded. Trade incentives, such as cash incentives, volume discounts and rebates, and free or discounted goods and services, are recorded as a revenue reduction.

2. Billed revenue

Through distributors controlled directly and indirectly by Compass Gás e Energia, the Company provides natural gas distribution services in areas where it has concession rights. In general, the fair value and selling price of individual services are comparable.

Gas distribution revenue is recognized when its amount can be reliably measured, with income recognized in the same period that volumes are delivered to customers on the basis of monthly measurements.

3. Unbilled revenue

Unbilled gas revenue refers to the amount of gas delivered that has not yet been metered and billed to customers. This estimate is based on the period between the last measurement date and the last day of the month.

Actual volume billed may vary from estimates. The Company believes, based on past experience with similar operations, that the estimated amount of unbilled services will not differ significantly from the actual amount.

4. Concession construction revenue

The construction of the necessary infrastructure for gas distribution is regarded as a construction service provided to the Granting Authority, and revenue is recognized over time using the incurred cost method. The costs are deducted from income when they are incurred.

Advances received are accounted for as contractual liabilities.

5. Provided services

As services are performed, revenue is recorded over time. The stage of completion for determining the amount of revenue to be recognized is determined based on work-in-progress evaluations.

If the performance of services under a single contract spans multiple time periods, consideration is allocated based on their individual selling prices. Individual sales prices are based on the list prices at which the Cosan Group sells its services in separate transactions.

6. Energy trading

Through the delivery of electricity in a given period, the Company recognizes revenue from the sale of electricity at the fair value of the consideration. The measurement of the amount of energy delivered to the purchaser occurs monthly. As soon as they consume electricity, customers gain control over it. Monthly invoices are typically paid within 30 days of issuance.

125

Explanatory Notes to the Financial Statement

(In thousands ofReais, except when otherwise indicated)

Energy trading revenue is recorded based on bilateral contracts signed with market agents and duly registered with the Electric Energy Trading Chamber (Câmara de Comercialização de Energia Elétrica – “CCEE”).

Revenue is recognized on the basis of the energy sold and the prices specified in the terms of the supply and supply agreements. The subsidiary Compass Comercialização will be able to sell the generated energy in two environments: (i) in the Free Contracting Environment (Ambiente de Contratação Livre – ACL), where the commercialization of electric energy takes place through the free negotiation of prices and conditions between the parties, via bilateral contracts; and (ii) in the Regulated Contracting Environment (Ambiente de Contratação Regulada – ACR), where electricity is sold to distribution agents.

a)Short-term market

When transactions on the short-term market occur, the Company records revenue at the fair value of the consideration to be received. The energy cost for these operations is tied to the Differences Settlement Price (Preço de Liquidação de Diferenças – PLD).

b)Energy trading operations

Energy trading transactions occur on an active market and, for accounting measurement purposes, satisfy the definition of fair-value financial instruments.

The Company records revenue at the fair value of the consideration upon delivery of energy to the customer. In addition, unrealized net gains resulting from mark-to-market, which is the difference between contracted and market prices, are recognized as income for outstanding contracted net operations as of the date of the financial statements.

7. Logistics services provided

Income from services rendered is recognized when the subsidiary transfers to the counterparty the significant risks and benefits inherent in the provision of services, when it is probable that the economic benefits associated with the transaction will flow to the subsidiary, and when the related amount and costs can be reliably measured.

According to service orders or contracts, prices for services are fixed. Revenue consists primarily of rail freight, road freight, container transport, and port lifting services; consequently, the aforementioned criteria are typically met to the extent that the logistics service is offered.

8. Lease income

Rental income is recognized on a straight-line basis over the term of each contract since the contracts transfer to customers the right to use the assets for a period of time in exchange for payments that can be reliably measured.

9. Sale of investment properties

Income consists of the fair value of the consideration received or receivable for the sale of investment properties in the ordinary course of the subsidiaries' operations. The revenues are presented net of taxes, returns, rebates, and discounts, and in the consolidated financial statements, sales within the subsidiary are eliminated. Revenue is recorded when the subsidiary satisfies all obligations and promises outlined in the contract for the transfer of goods to the customer.

21.     FINANCIAL RESULT

Accounting policy:

Financial income consists of interest income on invested funds, dividends, gains in the fair value of financial assets measured at fair value through profit or loss, gains on remeasurement of any pre-existing interest in an acquisition in a business combination, gains on hedging instruments recognized in the results, and reclassifications of net gains previously recognized in other comprehensive income. Using the effective interest rate method, interest income is recorded as it is recognized in the results. Dividend income is recognized in the results on the date that the Company's right to receive payment is established, which is typically the ex-dividend date for listed securities. 

Financial expenses consist of interest expenses on borrowings, settlement of discount provisions and deferrals, losses on the disposal of available-for-sale financial assets, dividends on preferred shares categorized as liabilities, losses on the fair value of financial assets at fair value through profit or loss contingent consideration and loss, impairment losses recognized in financial assets (other than accounts receivable), and losses on hedging instruments that are recognized.

The effective interest rate method is used to account for borrowing costs that are not directly attributable to the acquisition, construction, or production of an eligible asset.

Foreign exchange gains and losses on financial assets and liabilities are reported net as financial income or financial expense, based on whether net foreign currency fluctuations result in a gain or loss.

22.     POST-EMPLOYMENT BENEFIT

Accounting policy

Using actuarial valuations, the cost of defined benefit pension plans and other post-employment benefits, as well as the present value of the retirement obligation, are determined. A valuation based on actuarial principles is based on a number of assumptions that may differ from actual results in the future. These include determining the discount rate, salary increases in the future, death rates, and future pension increases. The sensitivity of a defined benefit obligation to changes in these assumptions is high. Management reviews all assumptions at each balance sheet date.

1. Defined contribution

A defined contribution plan is a post-employment benefit plan in which the Company pays fixed contributions to a separate entity and has no legal or constructive obligation to pay additional amounts. Obligations for contributions to defined contribution plans are recorded as an employee benefit expense in the financial results during the periods in which the related services are rendered by employees. Contributions to a defined contribution plan that are due more than 12 months after the end of the service period are discounted to their present value.

All employees are provided with a defined contribution plan. Comgás Pension Plan - PLAC and the Futura plan (Futura II - Complementary Pension Entity) are the plan's assets. The Group has no legal or constructive obligation to make additional contributions if the fund lacks sufficient assets to pay all benefits. 

2. Defined benefit

According to the regulation, which leads the Company to adopt such a provision in the present value of benefits and that assisted participants receive annuity according to the plan. The main actuarial risks are:

a)life expectancy longer than specified in the mortality table;

b)the return on equity under the actuarial discount rate plus the accrued IGP-DI; and

c)real family structure of different hypotheses of established retirement.

3. Health insurance 

The Comgás subsidiary provides a post-employment health care benefit to retired employees and their dependents who retired until May 31, 2000. After that date, only employees with 20 years of contribution to the INSS and 15 years of uninterrupted work at the Company as of May 31, 2000 are eligible for this defined benefit plan, provided they are still employed by the Company on the date the retirement is granted.

Independent actuaries calculate annually the liability reported in the balance sheet in relation to the defined benefit post-employment plan.

The amount recognized in the balance sheet in respect of post-employment benefit plan liabilities represents the present value of the obligations less the fair value of the assets, including actuarial gains and losses. Remeasurements of the net obligation, which include: actuarial gains and losses, return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in other comprehensive income. Net interest and other expenses related to the defined benefit plan are recognized in the result.

Actuarial gains and losses resulting from adjustments based on experience and changes in actuarial assumptions are recorded as other comprehensive income directly in shareholder’s equity when they occur.

a)Defined contribution

During the year ended December 31, 2022, the amount of employee contributions increased to R$303 (R$217 as of December 31, 2021).

b)Defined benefit

Futura: The subsidiary CLE sponsors Futura - Entidade de Previdência Complementar ("Futura"), formerly known as Previd Exxon - Entidade de Previdência Complementar, whose primary objective is to provide supplemental benefits within certain limits established by the Retirement Plan regulations. On 5 May 2011, the competent authorities authorized a modification to this plan to exclude new participants. The contributions totaled R$60,827 for the year ending December 31, 2022 (R$5,166 for the year ended on December 31, 2021). The obligation's weighted average duration is 8.7 years (9.6 years as of December 31, 2021).

c)Health insurance

Comgás: Obligations related to post-employment benefit plans, which include medical assistance and retirement incentives, sick pay and disability pension.

The defined benefit pension plan is governed by Brazilian labor laws, which mandate that final salary payments during retirement be adjusted for the consumer price index at the time of payment. The level of benefits provided is dependent on the member's length of service and final salary. During the year ended December 31, 2022, the contributions amounted to R$27,118 (R$25,169 for the year ended December 31, 2021). The weighted average duration of the obligation is 10.6 years (11.7 years in 2021).

Explanatory Notes to the Financial Statement

(In thousands of Reais, except when otherwise indicated)

Plan assets consist of financial assets quoted on active markets and are therefore classified as Levels 1 and 2 in the fair value hierarchy. The expected rate of return on plan assets is determined based on market expectations applicable to the period during which the obligation is to be settled at the time the rate is determined. 

The following are the primary assumptions used to determine the Company's and its subsidiaries' benefit obligations: 

	Future		Health insurance
	12/31/2022	12/31/2021	12/31/2022	12/31/2021
Discount rate	10.03%	8.64%	10.45%	9.09%
Inflation rate	3.50%	3.25%	4.25%	3.50%
Future salary increases	N/A	N/A	N/A	6.60%
Morbidity (aging factor)	N/A	N/A	3.00%	3.00%
Future pension increases	3.50%	3.25%	3.00%	3.00%
Overall mortality (segregated by sex)	N/A	N/A	AT-2000	AT-2000
Disability mortality	N/A	N/A	IAPB-1957	IAPB-1957
Entry into disability (modified)	N/A	N/A	Modified UP-84	Modified UP-84
Turnover	N/A	N/A	0.60/(service time +1)	0.60/(service time +1)

Sensitivity analysis

Changes in the discount rate to the date of the balance sheet is one of the relevant actuarial assumptions, while other assumptions are maintained, as it impacts the defined benefit obligation as shown below:

	Discount rate
	Increase	Reduction
	0.50%	(0.50)%
Future	(624,936)	674,988
medical plan	(21,878)	24,079

Regarding biometric and demographic assumptions and the methods used to prepare the sensitivity analysis, there was no change from previous years.

23. SHARE-BASED COMPENSATION

Accounting policy:

The fair value of share-based pay benefits at the grant date is recognized as personnel expenses, with a corresponding increase in shareholder’s equity, over the period during which employees acquire the unconditional right to receive the benefits.

The amount recognized as an expense is adjusted to reflect the number of shares for which there is a reasonable expectation that the service conditions and non-market acquisition conditions will be met, so that the final amount recognized as an expense is based on the number of shares that actually meet the service conditions and non-market acquisition conditions on the date the payment rights are acquired (vesting date). For non-vesting share-based payment benefits, the grant date fair value of the share-based payment is determined to reflect these conditions and is not adjusted for variances between expected and actual benefits.

The fair value of the amount payable to employees for cash-settled share appreciation rights is recorded as an expense and a corresponding increase in liabilities in the period in which employees acquire the right to payment. At each balance sheet date and on the settlement date, the liability is remeasured based on the fair value of the share appreciation rights. Any changes in the liability's fair value are recorded as personnel expenses in the result.

The Company and its subsidiaries have share-based compensation plans that are liquidated in both cash and shares. Grupo Cosan's share-based payment agreements as of December 31, 2022 are as follows:

Plans prior to 2021

(i)	Share grant plans (settled in shares), without lock-up, with delivery of shares at the conclusion of the 5-year grace period, subject only to the maintenance of the employment relationship (service condition).
(ii)	Share grant plans (settled in shares), without lock-up, with delivery of shares during or at the end of the grace period of three to five years, conditioned i) in part, on the maintenance of the employment relationship (service condition) and ii) in part, on the achievement of metrics comprising the performance targets (performance condition).
(iii)	Compensation plan based on shares (settled in cash) in which beneficiaries are assigned a certain number of units based on a theoretical share price derived from the Cosan Group's EBITDA for each year. Upon the completion of the three to five-year vesting period, the units will be paid out in cash. Payments are made at the conclusion of each cycle (between 3 and 5 years after the date of grant) based on the referenced converted value of the share at that time.

Grants made in 2022

• Share grant program (settled in shares)

135

Explanatory Notes to the Financial Statement

(In thousands of Reais, except when otherwise indicated)

In fiscal year 2022, the following Granting Programs were established:

Program	Conditions for rights acquisition
Cosan – Regular	3 years of service from the grant and achievement of specific metrics that can vary between 0% and 150% (for the calculation of the fair value, the achievement of 100% was considered). Performance actions will have a specific base weight, according to the target established by the Board of Directors.
Cosan – Partners	5 years of service from grant.
Rumo – Invest	5 years of service with annual delivery of shares from the grant and achievement of specific metrics.
Rumo – Special	3 years of service from the grant and achievement of specific metrics that can vary between 0% and 150% (for the calculation of the fair value, the achievement of 100% was considered).

In these programs, executives are entitled to shares with compensation of R$0.01 per share, with the concession contingent on meeting certain conditions for the acquisition of rights. Such holders have the same rights as holders of shares not subject to a vesting condition (e.g. dividends), so the value of the shares granted is equal to the value of the shares acquired.

• Share-based compensation plan (settled in cash and registered in liabilities – “Employee benefits payables”)

The subsidiary Compass carried out a phantom shares plan that provides for the granting of share appreciation rights (“SARs”) and other cash-based awards to certain employees. SARs provide the opportunity to receive a cash payment equal to the fair market value of the Company's common stock less the grant price.

The subsidiary Moove granted a Long-Term Incentive Plan "Moove Phantom Shares". This is a share plan in which beneficiaries are allotted a certain number of units based on an annual EBITDA-based theoretical share price calculation. The units will be paid out in cash upon completion of the 3 to 5 year vesting period stipulated in the contract. Payments are made at the conclusion of each cycle (three to five years after the date of grant) based on the referenced converted value of the share at that time.

The provision for future payments is accrued on a monthly basis based on quarterly-revised EBITDA projections.

24. RECENT ACCOUNTING STANDARDS ADOPTED BY THE COMPANY

Applicable standard	Main requirements	Impact
Amendments to IFRS 01/ CPC 37 Effective January 1, 2022.	The amendment allows a subsidiary that elects to apply paragraph D16(a) of IFRS 1 (equivalent to CPC 37 (R1) - Initial Adoption of International Accounting Standards) to measure cumulative translation differences using the amounts reported in the consolidated financial statements as of the parent's transition date to IFRS, if no adjustments were made for consolidation procedures and for the effects of the business combination in which the parent acquired the subsidiary. This modification also applies to a subsidiary or joint venture that elects to apply IFRS 1 paragraph D16(a).	These changes had no impact on the consolidated financial statements of the Cosan Group.
Amendments to IFRS 09/ CPC 48 Effective January 1, 2022.	The amendment clarifies the fees that an entity must consider when determining whether the terms of a new or modified financial liability differ materially from those of the original financial liability. These fees only include fees paid or received between the borrower and lender, including fees paid or received by either party on behalf of the other.	These changes had no impact on the individual and consolidated financial statements of the Cosan Group.
Amendments to IAS 41/ CPC 29 Effective January 1, 2022.	The amendment removes the requirement in paragraph 22 of IAS 41 that entities exclude cash flows for taxation when measuring the fair value of assets within the scope of IAS 41.	These changes had no impact on the individual and consolidated financial statements of the Cosan Group.
Amendments to IAS 37/ CPC 25 Effective January 1, 2022.	The Group adopted the IAS 37/CPC 25 amendments for the first time in the current year. The amendments stipulate that the "cost of performing" the contract includes "directly related costs." Costs directly associated with the contract include the incremental costs of fulfilling the contract (such as personnel or materials) and the allocation of other costs directly associated with fulfilling contracts (for example, allocating depreciation expense to an item of PPE used in the performance of the contract).	These changes had no impact on the individual and consolidated financial statements of the Cosan Group.
Amendments to IAS 16/ CPC 27 Effective January 1, 2022.	The amendment prohibits entities from deducting from the cost of a fixed asset any sales proceeds of produced items used to bring the asset to the location and to achieve the condition required for it to operate as intended by management. Instead, an entity recognizes the sales proceeds and production costs in the income statement.	These changes had no impact on the individual and consolidated financial statements of the Cosan Group.
Amendments to IFRS 3/ CPC 15 Effective January 1, 2022.	The amendments add an exception to the recognition principle of IFRS 3 (equivalent to CPC 15 (R1) - Business combinations) to prevent the issuance of potential 'day 2' gains or losses arising from liabilities and contingent liabilities that would be within the scope of IAS 37 Provisions, Contingent Liabilities and Contingent Assets (equivalent to CPC 25 - Provisions, Contingent Liabilities and Contingent Assets) or IFRIC 21 Levies, if incurred separately. The exception requires entities to use IAS 37 or IFRIC 21, rather than the Conceptual Framework, to determine whether a present obligation exists at the date of acquisition. In addition, a new paragraph is added to IFRS 3 to clarify that contingent assets are not eligible for recognition on the date of acquisition.	These changes had no impact on the individual and consolidated financial statements of the Cosan Group.

25. NEW STANDARDS AND INTERPRETATIONS NOT YET IN FORCE

The CPC and IASB issued the following new standards, interpretations, and amendments, but they are not applicable for annual periods beginning after January 1, 2022. Premature adoption is prohibited. In addition, the Company believes, based on an initial review, that the adoption of the following standards/amendments will not have a material impact on its consolidated results or financial position.

Applicable standard	Major requirements or changes to accounting policy
Amendments to IAS 1/ CPC 26 and IFRS Practice Statement 2 Making Materiality Judgments Effective January 1, 2023.	In January 2020, the IASB issued amendments to paragraphs 69 to 76 of IAS 1, which correspond to CPC 26, to specify the classification requirements for current or noncurrent liabilities. The modifications are applicable to periods beginning on January 1, 2023, and must be applied retroactively. The Group is currently evaluating the effect of the proposed changes on current practice. The IASB issued amendments to IAS 1 (the corresponding standard to CPC 26 (R1)) and IFRS Practice Statement 2 Making Materiality Judgments in February 2021. These amendments provide entities with guidance and examples on how to apply materiality judgments to the disclosure of accounting policies. The amendments to IAS 1 are effective for periods beginning on or after 1 January 2023, with early adoption permitted. As the amendments to Practice Statement 2 provide non-obligatory guidance on the application of the material definition to accounting policy reporting, an adoption date is not required for this amendment. The Cosan Group is currently reviewing the accounting policy disclosures to ensure they are consistent with the required changes.
IFRS 17/ CPC 50 Insurance Contracts Effective January 1, 2023.	The purpose of IFRS 17 is to provide insurers with a more useful and consistent accounting model for insurance contracts. For periods beginning on or after January 1, 2023, IFRS 17 and CPC 50 require the presentation of comparative values. IFRS 17 may be adopted early if IFRS 9 and IFRS 15 are also adopted on the same date or before the initial adoption of IFRS 17. The Cosan Group is not significantly affected by this standard.
Amendments to IAS 8/ CPC 23 Effective January 1, 2023.	The IASB issued amendments to IAS 8 (the corresponding standard to CPC 23) in February 2021, introducing the definition of "accounting estimates." The modifications clarify the distinction between changes in accounting estimates, accounting policy changes, and error correction. In addition, they specify how entities should utilize measurement techniques and inputs to develop accounting estimates. The amendments will apply to changes in accounting policies and estimates that occur on or after January 1, 2023, for periods beginning on or after that date. Premature adoption is permissible if disclosed. The modifications are not anticipated to have a substantial impact on Cosan Group's financial statements.
Amendments to IAS 12/ CPC 32 Effective January 1, 2023.	In May 2021, the Board issued amendments to IAS 12 that restrict the scope of the initial recognition exception so that it no longer applies to transactions that result in equal taxable and deductible temporary differences. The modifications are applicable to transactions that occur in annual periods beginning on or after the earliest comparable period presented. In addition, a deferred tax asset (provided there is sufficient taxable profit available) and a deferred tax liability should be recognized at the beginning of the earliest comparative period presented for all deductible and taxable temporary differences associated with leases and decommissioning obligations. The Cosan Group is currently evaluating the effects of these modifications.
Amendments to IFRS 16/ CPC 06 Effective January 1, 2024.	The Board issued amendments to IFRS 16 regarding sale and leaseback transactions in September 2022. The amendment to IFRS 16 specifies the requirements that a seller/lessee must adhere to when calculating the lease liability arising from a sale-and-leaseback transaction, so that the seller/lessee does not recognize any gain or loss related to the right-of-use. The Group is currently evaluating the effects of these modifications.

All other standards or amendments to standards issued by the CPC and IASB and which are effective as of January 1, 2022 are not applicable or relevant to the Company.
