NYSE American LLC (“NYSE American” or the “Exchange”) announced today that the staff of NYSE Regulation has determined to suspend trading in the two securities enumerated below (“Securities”) of Ambipar Emergency Response (the “Company”) from NYSE American.

The Exchange previously announced on October 22, 2025 that the Company was no longer suitable for listing pursuant to Section 1003(c)(iii) of the NYSE American Company Guide in light of the Company’s disclosure on October 21, 2025 announcing that it filed for Chapter 11 with United States Bankruptcy Court for the Southern District of Texas, Houston Division. The Company had the right to request a review of this determination by the Listings Qualifications Panel of the Committee for Review of the Board of Directors of the Exchange. On October 28, 2025, the Company confirmed that it will not exercise that right. Accordingly, the NYSE American will now suspend trading in the Company’s Securities and will file a delisting application with the Securities and Exchange Commission.
