Independent auditor´s review report on quarterly information

Shareholders, Board of Director and Officers of

Cosan S.A.

São Paulo - SP

Introduction

We have reviewed the accompanying individual and consolidated interim financial information, contained in the Quarterly Information Form (ITR) of - Cosan S.A. (“Company”) for the quarter ended June 30, 2021, comprising the statement of financial position as of June 30, 2021 and the related statements of profit or loss and of comprehensive income, for the three and six month periods then ended, and the statements of changes in equity and of cash flows for the six month period then ended, including the explanatory notes.

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

Scope of review

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

Conclusion on the individual and the consolidated interim financial information

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

Emphasis of matter

Restatement of Earnings per share and Operating segments

As mentioned in Note 16, due to the share split, the Company adjusted earnings per share and the related notes for the three and six month period ended June 30, 2020, as provided for in Brazilian Accounting Standard CPC 41 – Resultado por ação / IAS 33 – Earnings per share. Additionally, as mentioned in Note 4, due to the change in the structure of operating segments, the Company adjusted the disclosure of operating segments for the three and six month period ended June 30, 2020, as provided for in Brazilian Accounting Standard CPC 22 – Informações por Segmento / IFRS 8 – Operating Segments. Our conclusion is not modified in respect of these matters.

Other matters

Statements of value added

The abovementioned quarterly information includes the individual and consolidated statements of value added (SVA) for the six-month period ended June 30, 2021, prepared under Company’s Management responsibility and presented as supplementary information by IAS 34. These statements have been subject to review procedures performed together with the review of the quarterly information with the objective to conclude whether they are reconciled to the interim financial information and the accounting records, as applicable, and if its format and content are in accordance with the criteria set forth by NBC TG 09 Demonstração do Valor Adicionado. Based on our review, nothing has come to our attention that causes us to believe that they were not prepared, in all material respects, consistently with the overall interim financial information.
