Sao Paulo, August 30, 2024 - Ultrapar Participacoes S.A. (B3: UGPA3 / NYSE: 
UGP, "Ultrapar"), in compliance with CVM Resolution 44/21, through its 
subsidiary Ultrapar Logistica Ltda., hereby informs that it publicly assumed 
on this date its intention to exercise its preemptive right in the 
subscription of shares to be issued by Hidrovias do Brasil S.A. (B3: HBSA3, 
"HBSA") due to the capital increase of
up to R$ 1.5 billion
to be approved by the general shareholders' meeting of HBSA, through the 
issuance for private subscription of new common shares, at an issue price of 
R$ 3.40/share.

As disclosed by HBSA on this date, said capital increase aims to strengthen 
HBSA's capital structure in order to enable the implementation of its growth 
plan and value generation, including by carrying out of the investments 
foreseen therein and reducing the level of indebtedness.

The subscription of HBSA shares reinforces the alignment of Ultrapar's 
strategy of expanding its presence in sectors exposed to the Brazilian 
agribusiness, as well as Ultrapar's role as a strategic long-term reference 
shareholder of HBSA, supporting its growth, governance and management model.


The Company will maintain the market and its shareholders duly informed.
