São Paulo, July 31, 2018 – Ultrapar Participações S.A. informs that, according to the media, the Public Prosecutor for the Consumer Division in the city of Curitiba and the Parana State Police Anti-Corruption Division initiated today the operation called “Controlled Margin” in the city of Curitiba, Parana state, involving employees from fuel distribution companies, among them Ipiranga Produtos de Petróleo S.A. According to information provided by the Public Prosecutor in the state of Parana, this is an investigation on suspicion of fuel-price fixing at the pump in branded gas stations in the city of Curitiba. Ipiranga will evaluate the facts attributed to its employees and it is available to clarify any inquiry from the authorities.

Also on this date, Ipiranga became aware of the receipt of the criminal complaint filed by the Public Prosecutor of the First Criminal Court of Brasilia against resellers and employees of distribution companies, among which two former employees of Ipiranga, for alleged criminal acts against the economic order. The referred decision determined the blockade of assets and financial investments of individuals and companies, including R$ 156 million of bank accounts of Ipiranga, which is not a party in the process and will appeal against such decision.

Ultrapar reinforces its commitment to the highest ethical standards, as well as with the best competitive practices and respect to the consumer. The Company emphasizes that it does not promote illegal practices and does not tolerate activities that violate its Compliance Program, besides valuing transparency and ethics in all its actions and relations.
