The board of directors of Ambipar Emergency Response (the “Company” or “we”) is soliciting proxies for the annual general meeting of shareholders (the “AGM”) of the Company to be held on December 16, 2024 at 10:00 a.m. (Brasilia time). The AGM will be held at Avenida Angélica, nº 2346, 5th Floor, São Paulo, São Paulo, Brazil, 01228-200.
A copy of this proxy statement and our annual report on Form 20-F for the fiscal year ended December 31, 2023 can be accessed, free of charge, on the “Corporate Governance – General Shareholders’ Meeting” section and “Financial Information – SEC Filings” section, respectively, of the Company’s website at https://ir-response.ambipar.com, on the platform hosted by Continental at https://www.cstproxy.com/ambipar/2024 and at the SEC’s website at www.sec.gov.
By inserting the control number to be provided to you on your Notice of Internet Availability of Proxy Materials or proxy card at www.cstproxyvote.com for registered shareholders and at www.proxyvote.com for street shareholders (if your bank, brokerage firm, or other nominee supports www.proxyvote.com and has agreed to provide you with a control number for this purpose), you will have instructions on how to access our proxy materials, and on how to vote via the Internet or by proxy card. If you own shares in street name, meaning that your shares are held by a bank, brokerage firm, or other nominee, you may also instruct that institution on how to vote your shares.
On or about December 6, 2024, we expect to mail to our shareholders a Notice of Internet Availability. See “Internet Availability of Proxy Materials” below.
Record Date, Share Ownership and Quorum
Only the holders of record of Class A Ordinary Shares and Class B Ordinary Shares (the “Ordinary Shares”) of the Company as at the close of business on November 26, 2024, Cayman Islands time (the “Record Date”) are entitled to receive notice of and attend the AGM and any adjournment thereof. No person shall be entitled to vote at the AGM unless it is registered as a shareholder of the Company on the record date for the AGM.
As of the close of business on the Record Date, 55,429,851 Ordinary Shares were issued and outstanding, including 16,195,105 Class A Ordinary Shares and 39,234,746 Class B Ordinary Shares. One or more shareholders holding not less than one-third in aggregate of the voting power of all shares in issue and entitled to vote, present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative, constitutes a quorum of the shareholders.



Voting and Solicitation
Each Class A Ordinary Share issued and outstanding as of the close of business on the Record Date is entitled to one vote at the AGM. Each Class B Ordinary Share issued and outstanding as of the close of business on the Record Date is entitled to ten votes at the AGM. The ratification and approval of the financial statements and the auditor’s report for the fiscal year ended December 31, 2023 will require approval by an ordinary resolution (i.e., a simple majority of the votes cast, by or on behalf of, the shareholders attending and voting at the AGM).
Internet Availability of Proxy Materials
We are furnishing proxy materials to our shareholders primarily via the Internet, instead of mailing printed copies of those materials to each shareholder.
On or about December 6, 2024, we expect to mail to our shareholders a Notice of Internet Availability containing instructions on how to access our proxy materials. The Notice of Internet Availability of Proxy Materials directs shareholders to a website where they can access our proxy materials, including our proxy statement and our annual report, and view instructions on how to vote via the Internet or by proxy card. This process is designed to expedite shareholders’ receipt of proxy materials, lower the cost of the AGM, and help conserve natural resources. If you received a Notice of Internet Availability of Proxy Materials and would prefer to receive a paper copy of our proxy materials, please follow the instructions included in the Notice of Internet Availability of Proxy Materials.
Voting by Holders of Ordinary Shares
Ordinary Shares that are properly voted via the Internet or for which proxy cards are properly executed and returned within the deadline set forth below, will be voted at the AGM in accordance with the directions given. The proxy holder will also vote in the discretion of such proxy holder on any other matters that may properly come before the AGM, or at any adjournment thereof. Where any holder of Ordinary Shares affirmatively abstains from voting on any particular resolution, the votes attaching to such Ordinary Shares will not be included or counted in the determination of the number of Ordinary Shares present and voting for the purposes of determining whether such resolution has been passed (but they will be counted for the purposes of determining the quorum, as described above).
Voting via the Internet helps save money by reducing postage and proxy tabulation costs. Each of these voting methods is available 24 hours per day, seven days per week. To vote by any of these methods, read this Proxy Statement, have your Notice of Internet Availability of Proxy Materials or proxy card in hand, and follow the instructions set forth in the Notice of Internet Availability of Proxy Materials or proxy card, as the case may be.



Proxies submitted by registered shareholders and street shareholders (whether by internet or by returning the proxy card) must be received by us no later than 11:59 p.m., Eastern time, on December 15, 2024 to ensure your representation at our AGM.
The manner in which your shares may be voted depends on how your shares are held. If you own shares of record, meaning that your shares are represented by book entries in your name so that you appear as a shareholder on the shareholder register of the Company maintained by Continental (i.e., you are a registered shareholder), our stock transfer agent, this proxy statement, the notice of AGM and the proxy card will be available to you at www.cstproxyvote.com by inserting the control number on the Notice of Internet Availability of Proxy Materials or proxy card to be provided to you by Continental. You may provide voting instructions by Internet or (if you have received paper copies of our proxy materials) by returning a proxy card. You also may attend the AGM and vote in person. If you own Ordinary Shares of record and you do not vote by Internet, proxy or in person at the AGM, your shares will not be voted.
If you own shares in street name (i.e., you are a street shareholder), meaning that your shares are held by a bank, brokerage firm, or other nominee, you are then considered the “beneficial owner” of shares held in “street name,” and as a result, this proxy statement, the notice of AGM and the proxy card will be available to you at www.proxyvote.com by inserting the control number on the instructions to be provided to you by your bank, brokerage firm, or other nominee holding the shares if your bank, brokerage firm, or other nominee supports www.proxyvote.com and has agreed to provide you with a control number for this purpose. You may provide voting instructions by the Internet or (if you have received paper copies of proxy materials through your bank, brokerage firm, or other nominee) by returning a voting instruction form received from that institution. If you own Ordinary Shares in street name and attend the AGM, you must obtain a “legal proxy” from the bank, brokerage firm, or other nominee that holds your shares in order to vote your shares at the meeting and present your voting information card.
Revocability of Proxies
Registered shareholders may revoke their proxy or change voting instructions before shares are voted at the AGM by submitting a written notice of revocation to our Investor Relations Department at https://ir-response.ambipar.com, or a duly executed proxy (via the Internet or by returning a proxy card) bearing a later date (which must be received by us no later than the date set forth below) or by attending the AGM and voting in person. A beneficial owner owning Ordinary Shares in street name may revoke or change voting instructions by contacting the bank, brokerage firm, or other nominee holding the shares or by obtaining a legal proxy from such institution and voting in person at the AGM. If you are not planning to attend in person our AGM, to ensure your representation at our AGM, any changes to the voting instructions of proxies previously submitted by registered shareholders and street shareholders (whether by internet or by mailing a proxy card) must be received by us no later than 11:59 p.m., Eastern time, on December 15, 2024.
