Equity and Voting Structure


Corporate History

Ambipar was founded in 1995 and has grown into a multinational leader in recycling, waste management, and emergency response services with operations in Brazil and around the world.


Operations Overview

The Debtor is a holding company that conducts no operations and has no employees. Its primary function is to hold equity interests in the subsidiaries that constitute the global Response business. The Debtor believes its "center of main interests" is in Brazil.

Operational Independence of Subsidiaries


Prepetition Obligations

The Debtor’s primary prepetition liabilities stem from its limited guarantees on two series of New York-law governed Green Notes issued by a financing affiliate, Ambipar Lux S.à.r.l. (“Ambipar Luxco”). Aside from these guarantees and intercompany loans, the Debtor has no other outstanding indebtedness.

Events Leading to Bankruptcy

The Debtor’s Chapter 11 filing is a direct result of the financial distress of its parent, Ambipar Topco, and certain Brazilian affiliates, despite the continued operational strength of the Response business. The crisis was triggered in September 2025 by a series of events that undermined market confidence.
