The current management of IRB-Brasil Resseguros S.A.

In this context, in April 2023, the Company entered into a Non-Prosecution Agreement ("NPA" or the "Agreement") with the U.S. Department of Justice ("DOJ" or the "U.S. authorities"), primarily concerning inaccurate information regarding the Company's shareholder base that was disseminated in the United States between February and March 2020.

Pursuant to the terms of the NPA, the Company made available an amount of US$ 5 million as compensation and committed to cooperating with the U.S. authorities to enhance its internal controls, corporate governance, and compliance practices for a period of up to three years.

Throughout this period, IRB(Re) fully complied with all obligations undertaken under the NPA - including the implementation of a program to strengthen its internal controls, Governance, and compliance practices - and cooperated diligently and continuously with the U.S. authorities, carrying out all monitoring activities and periodic reporting requirements established under the Agreement.

With the expiration of the Agreement, IRB(Re) considers all its obligations under the NPA with the U.S. authorities to have been fulfilled and concluded. The Company reaffirms its commitment to transparency and the continuous enhancement of its corporate governance framework in support of its future growth.
