MARKET ANNOUNCETMENT

Investment plan for 2025

São Paulo, February 6th, 2025 – Ultrapar Participações S.A., informs its investment plan for 2025, approved by the Board of Directors.

2025 Organic investment plan ¹

¹ Net of divestments

2 Includes financing to clients, net of receipts

Ultrapar’s consolidated investment plan for 2025 totals R$ 2,542 million, R$ 136 million lower than the announced plan for 2024, mainly due to the conclusion of Ultracargo’s expansions.

The portion of investments in expansion (~60% of the total) prioritizes investments for the continued growth of the businesses, through capacity and capillarity expansion, and efficiency and productivity gains.

At Ipiranga, investments in expansion are focused on the branding of service stations, the expansion of the logistics infrastructure, and the TRR segment.

At Ultragaz, investments in expansion are mainly focused on capturing new customers in the bulk segment, expanding new energies and infrastructure.

Ultracargo will focus its expansion investments mainly on concluding the increase in installed capacity at Santos (SP), Palmeirante (TO), and Rondonópolis (MT), the Opla railway branch, and the ongoing expansion in Itaqui (MA). Additionally, the plan considers the start of expansion in Suape (PE), with 40,000 m3 increase in installed capacity, expected to be completed in 2026.

Maintenance investments (~40% of the total) will be allocated to the sustaining of the business, and mainly include investments in assets’ maintenance, safety, revitalization of services station, and acquisition of bottles. Additionally, Ipiranga will invest in its technology platform for ERP and satellite systems, with productivity and efficiency gains.
