Excerpts of this announcement relating to Ambipar Emergency Response (the “Company”) are furnished as Exhibit 99.1 to this Report on Form 6-K. Financial information relating to the Company contained therein has not been audited or reviewed in accordance with the standards of the Public Company Accounting Oversight Board (PCAOB) or any other auditing standards. While such financial information has been prepared in good faith and based on information available at the time of preparation, no assurance can be made that actual results will not change as a result of the Company’s management review of results and other factors. The Company’s results for the nine months ended September 30, 2023 are subject to finalization and closing of the Company’s accounting books and records (which have yet to be performed) and should not be viewed as a substitute for financial statements prepared in accordance with IFRS.
