MARKET ANNOUCEMENT

 

Signing of agreement for the acquisition of a stake in Virtu GNL

  

São Paulo, October 24, 2025 - Ultrapar Participações S.A. (B3: UGPA3 / NYSE: UGP, “Ultrapar”), in compliance with CVM Resolution 44/21, hereby informs that it has signed an agreement for the acquisition (“transaction”) of a 37.5% stake in Virtu GNL Participações S.A. (“Virtu”).

 

Virtu operates under two business models: (i) liquefied natural gas (“LNG”) logistics for its own use and for Eneva’s clients through a joint venture; and (ii) LNG-powered logistics services, including the operation of refueling stations dedicated to its fleet of LNG-powered trucks. Virtu has been consolidating its position as a key player in low-carbon solutions for the road transportation sector, focusing on replacing diesel with LNG, particularly to support the transportation of Brazil’s growing agricultural production in the country´s Midwest and North regions.

Ultrapar will invest R$ 102.5 million in the transaction, with R$ 85.0 million allocated as a capital contribution to Virtu and the remaining balance will be paid as a secondary transaction.

The resulting corporate structure will establish a control block shared between Ultrapar and Perfin Infra (an infrastructure investment fund), holding 75% of the voting capital, while the founding partner, José Moura Jr., will remain a significant shareholder with 25%. This structure will enable Ultrapar to support the company’s commercial and strategic development, growth, governance, and management practices.

Ultrapar’s entry into this market aligns with its strategy of investing in new sectors where it can contribute to value creation, with high potential for both growth and profitability.

The completion of this transaction remains subject to regulatory approvals and the fulfillment of customary conditions precedent for this type of operation.
