São Paulo, April 5, 2019 – Ultrapar Participações S.A. (B3: UGPA3; NYSE: UGP, “Ultrapar” or “Company”) hereby informs that its subsidiaries Ipiranga and Ultracargo won concessions’ auctions to operate areas in ports for storage and handling of liquid bulk, specially fuels. The process was concluded today after the bidding process held by the National Agency for Waterway Transportation – ANTAQ, at B3 headquarters in São Paulo.

Ipiranga won two concessions in the port of Miramar, in Belém, state of Pará: (i) area BEL02A, through a consortium 50% owned by Ipiranga, that shall have minimum storage capacity of 41 thousand m³, and (ii) area BEL04A, which is currently operated by Ipiranga, therefore maintaining its operation in the region, with minimum storage capacity of 23 thousand m³. Such areas will be operated for at least 15 years, according to the auction notice.

Ultracargo won the concession of area VDC12 in the port of Vila do Conde, in Barcarena, state of Pará. The minimum storage capacity will be 59 thousand m³ and initial operations are expected for 2023. The area will be operated by Ultracargo for at least 25 years, according to the auction notice.

The estimated investments regarding the participation of Ipiranga and Ultracargo sums up to R$ 450 million, approximately, to be disbursed throughout the next five years, including the auction grants and the minimum investment required for these areas, and will contribute to improve logistics efficiency, job creation and development in the region.

Vila do Conde Port has a deep draft which allows the docking of large vessels. Additionally, both ports are strategically located, enabling the Company to supply fuels mainly in the state of Pará, a state that presents superior growth compared to the national average.
