São Paulo, September 9, 2020 – Ultrapar Participações S.A. (B3: UGPA3 / NYSE: UGP, “Company” or “Ultrapar”), in compliance with article 12 of CVM Instruction nr. 358/02, hereby informs that it was notified by Ultra S.A. Participações (“Ultra S.A.”) that on September 9, 2020, it surpassed the 25% threshold (which triggers a notification according to the Brazilian regulation) and reached a relevant ownership position of 25.08% of the total ordinary shares issued by Ultrapar, totaling 279,593,690 shares. The increase in its position reflects the completion of the capital subscription of Ultra S.A. capital stock by Pátria Private Equity VI FIP Multiestratégia (“Pátria”), as announced in the Company’s Material Notice of August 18, 2020. Pátria’s interest in Ultra S.A.’s total capital remained unchanged.

Ultra S.A. also stated that it aims to reinforce the principles that have ruled the performance of Ultrapar's reference shareholders for the continuous protection of all shareholders’ interests and the assurance that the Company continues to be managed professionally and independently. The letter sent by Ultra S.A. is attached.
