### Footnotes:

(1) The filing of this Form 3 shall not be construed as an admission that Victor B. Almeida (the "Reporting Person") is or was for the purposes of Section 16(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise the beneficial owner of any (i) Class A Ordinary Shares, par value $0.0001 per share ("Ordinary Shares"), of Ambipar Emergency Response (the "Issuer"), or (ii) Warrants of the Issuer ("Warrants") exercisable for Class A Ordinary Shares.  Pursuant to Rule 16a-1(a)(4) of the Exchange Act, the Reporting Person disclaims such beneficial ownership, except to the extent of his pecuniary interest.

(2) The Reporting Person serves as a member of the board of directors of the Issuer as the representative of Opportunity Private Equity Gestora de Recursos Ltda. ("OPEG").  OPEG is the investment manager of Opportunity Dinamico Fundo de Investimento em Participacoes Multiestrategia Responsabilidade Limitada (the "Fund"), which is the direct beneficial owner of 11,810,000 Ordinary Shares and 2,280,000 Warrants.  OPEG, although it directs the voting and disposition of the Ordinary Shares and Warrants held by the Fund, only receives an asset-based fee and performance fee relating to such securities.  The Reporting Person, as a Partner holding less than 10% of OPEG and an indirect investor in the Fund, may be deemed an indirect beneficial owner of the securities reported herein.

(3) Pursuant to the Warrant Agreement dated July 15, 2020, and the Form 20-F of the Issuer filed with the Securities and Exchange commission on June 24, 2025, each Warrant (i) is exercisable into one Ordinary Share at a price of $11.50, subject to adjustment as specified therein, during the period described therein and (ii) expires on March 3, 2028.
