    Explanation of Responses:
    1. The filing of this Form 3 shall not be construed as an admission that Opportunity Private Equity Gestora de Recursos Ltda. ("OPEG") 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, OPEG disclaims such beneficial ownership, except to the extent of its pecuniary interest.
    2. 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.
    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.
    Remarks:
    Victor B. Almeida, a Partner holding less than 10% of OPEG, serves as a member of the board of directors of the Issuer as the representative of OPEG. In connection therewith, OPEG may be deemed to be a director by deputization of the Issuer solely for purposes of Section 16(a) of the Exchange Act. As a result, OPEG is listed as a "Reporting Person" in Item 1 and the "Director" box is marked in Item 4 of this Form 3.
