Rio de Janeiro, March 31, 2020 - Petro Rio SA (“Company” or “PetroRio”) (B3: PRIO3), announces to its shareholders and the market in general that it has hired Ernst & Young Auditores Independentes SS (“EY”) as external and independent auditors for the Company's annual financial statements and quarterly financial information, thus replacing the previous auditors Lopes, Machado Auditores (“BKR”).

The replacement is in line with best practices in Corporate Governance and will allow EY to perform its independent audit services as from Q1, 2020.

Such contract obtained the due consent of BKR and aims to meet, among other reasons, the provisions of article 31 of CVM Instruction 308/99, which determines the rotation of independent auditors every five years. PetroRio extends its gratitude for the quality services provided by BKR in the more than four in which it served as an independent auditor of the Company.
