Introduction

We have reviewed the Company and consolidated interim financial information, of Trisul S.A. ("Company"), included in the Interim Financial Information Form for the quarter ended September 30, 2021, which comprises the balance sheet as at September 30, 2021 and the related income statement and statements of comprehensive income for the three- and nine-month periods then ended, and changes in equity and cash flows for the nine-month period then ended, including the summary of the main accounting policies and other explanatory information.

Management is responsible for preparing the individual and consolidated interim financial information in accordance with Technical Pronouncement CPC 21 (R1) - Interim Financial Statements and the consolidated interim financial information in accordance with CPC 21 (R1) and IAS 34 - Interim Financial Reporting, which comprise the understanding expressed by the CVM through Circular Letter CVM/SNC/SEP No. 02/2018 on the application of NBC TG 47 (IFRS 15) regarding aspects related to the transfer of control to the recognition of income from agreements for the purchase and sale of real estate under construction, applicable to real estate project entities in Brazil, as well as the presentation of such information in compliance with the standards issued by the Brazilian Securities and Exchange Commission, applicable to the preparation of Interim Financial Information. Our responsibility is to express an opinion on these interim financial information based on our review.

Scope of the review

We conducted our review in accordance with Brazilian and international standards on review of interim financial information (NBC TR 2410 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 the standards on auditing 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.

Based on our review, nothing has come to our attention that causes us to believe that the Company interim financial information included in the Interim Financial Information Form referred to above is not prepared, in all material respects, in accordance with CPC 21 (R1) - Interim Financial Reporting, taking into account the guidance included in Circular Letter/CVM/SNC/SEP No. 02/2018 on the application of NBC TG 47 (IFRS 15), regarding aspects on the transfer of control to the recognition of revenue in purchase and sale agreements of real estate under construction, as well as the presentation of such financial information in compliance with the standards issued by the Brazilian Securities and Exchange Commission, applicable to the preparation of the Interim Financial Information.

Conclusion on the consolidated interim financial information prepared

Based on our review, nothing has come to our attention that causes us to believe that the consolidated interim financial information included in the QFI referred to above is not prepared, in all material respects, in accordance with CPC 21 (R1) and IAS 34 - Interim Financial Reporting, taking into account the guidance included in Circular Letter/CVM/SNC/SEP No. 02/2018 on the application of NBC TG 47 (IFRS 15), regarding aspects on the transfer of control to the recognition of revenue in purchase and sale agreements of real estate under construction, applicable to real estate project entities in Brazil, as well as the presentation of such financial information in compliance with the standards issued by the Brazilian Securities and Exchange Commission, applicable to the preparation of the Interim Financial Information.

Emphasis of a matter
