TIM S.A. has made a significant change in its independent auditors, a move that underscores its commitment to regulatory compliance and transparency. On November 9, 2026, the company's Board of Directors approved the replacement of Ernst & Young Auditores Independentes S/S. with Deloitte Touche Tohmatsu Auditores Independentes Ltda. and Grant Thornton Auditores Independentes Ltda. for its financial audits.

This decision is particularly important as it comes in the wake of changes in the company’s shareholding control. The selection of new auditors aims to meet the independence requirements outlined in CVM Resolution No. 23, which governs such matters in Brazil.

Background

TIM S.A. operates within the telephone communications sector, specifically classified under SIC 4813. The company is publicly traded under the ticker TIMB on the New York Stock Exchange. As a large accelerated filer, TIM is subject to stringent reporting and regulatory standards, which necessitate regular updates on its financial practices and partnerships.

What the Filing Says

According to the SEC filing, "the Board of Directors approved the replacement of Ernst & Young Auditores Independentes S/S. with Deloitte Touche Tohmatsu Auditores Independentes Ltda. to provide independent audit services in connection with the Company’s financial statements for the fiscal year ending December 31, 2026." Additionally, Grant Thornton has been selected to audit the consolidated financial statements.

Impact

This change in auditors may have several implications for TIM S.A. and its stakeholders. Shareholders and investors may view this move as a positive step toward greater transparency and compliance with regulatory standards. Furthermore, the decision could influence other companies in the telephone communications sector to reassess their audit relationships, particularly in light of the evolving regulatory landscape.

What's Next

The execution of the respective engagement letters for the new auditors is still pending and will be subject to the applicable procedures. Further updates from TIM S.A. are expected as these processes unfold.
