COMMUNICATION ON CORPORATE DEMAND

Rio de Janeiro, June 9th, 2022 - IRB-Brasil Resseguros S.A. (B3: IRBR3) ("IRB Brasil RE" or "Company"), in compliance with art. 33, XLIII, and Annex I of CVM Resolution No. 80/22, informs its shareholders and the market in general the information below, referring to the CAM Arbitration Procedure No. 213/22, whose purpose is similar to that discussed in other arbitration proceedings involving the Company already disclosed in its Reference Form:

• Parties:Mr. Cicero Antonio Almeida Gonçalves, as claimant ("Applicant"), and the

Company, as defendant;

• Amount involved:R$ 91,390.99 (amount attributed by the Applicant to the case);
• Summary of the facts narrated by the Claimant:since the end of 2019, the price of the Company's shares would be falling due to the publication of untrue news about its shareholding base and its accounting information. The shares held by the Claimant between February 3, 2020 and March 4, 2020 would have devalued as a result of these alleged facts, which is why the Claimant requires the Company to reimburse him for the lost amounts;
• Requests: (i) condemnation of the Company to pay the loss allegedly suffered by the Claimant, in the amount of R$91,390.99, plus interest and monetary restatement; (ii) incidence of the Consumer Defense Code to reverse the burden of proof; and (iii) condemnation of IRB Brasil RE to the payment of fees to be arbitrated at 20% of the value of the case.
