Ultrapar announces the closing of the sale of Oxiteno

São Paulo, April 1, 2022 – Ultrapar Participações S.A. (B3: UGPA3 / NYSE: UGP, “Ultrapar" or “Company”) in addition to the Material Notice of August 16, 2021 and the Market Announcement of March 7, 2022, announces the conclusion of the sale of Oxiteno S.A. – Indústria e Comércio (“Oxiteno”) to Indorama Ventures PLC.

Pursuant to the Share Purchase Agreement, the initial payment of US$ 1,150,000,000.00, adjusted by the variations in working capital and net debt position of US$ 176,355,814.16, resulted in the total initial payment of US$ 1,326,355,814.16, which was settled today. This amount is still subject to final working capital and net debt adjustments. The final payment of US$ 150,000,000.00 will be settled in April 2024.

Consistent with the information that the Company has been providing to its shareholders and to the capital markets, the sale of Oxiteno is an important step of Ultrapar’s portfolio review process, seeking greater complementarity and synergies among its businesses.
