Brazil’s Superior Tribunal de Justiça stopped Ambipar’s creditors from voting on its rescue plan. The order landed on 1 September 2026, hours before they were due to meet.
Minister Raul Araújo did more than pause the vote. He also froze the Rio de Janeiro ruling that had settled which court hears the case.
What the Order Does
The STJ is Brazil’s highest court for matters that do not turn on the constitution. Minister Araújo sits in its fourth panel and has handled this venue fight before.
He gave the creditors’ appeal suspensive effect, which freezes the decision under challenge. That decision was the Rio appeal court ruling naming Rio as the proper forum.
So the venue ruling and the meeting are both on hold. Nothing moves until Araújo decides.
In his reasoning he said the group’s structure needs a closer look. The question is whether Ambipar earns the most in the same place it makes its decisions.
Where Ambipar Says It Is Based
That question has an awkward history. Ambipar told the Brazilian courts its main establishment is in Rio, and filed there in October 2025.
In July 2026 it said something else in a Texas bankruptcy court. There it described its Brazilian operations as headquartered in São Paulo.
Its emergency response arm had filed for Chapter 11 in that court. The contradiction is what put the venue fight back in play.
Who Is Pushing for São Paulo
The group that went to the STJ is broader than a set of banks. It filed on 31 August 2026, the day before the meeting.
It comprised Vinci Compass, Oliveira Trust, Sumitomo Mitsui Brasileiro and Banco do Brasil. ABC Brasil and the distressed debt firm Jive joined them.
Oliveira Trust acts as fiduciary agent for the debenture holders. Vinci had bought Santander’s claims, worth about 660 million reais (US$128 million).
An earlier venue challenge came from Bradesco, Santander, Itaú, Caixa, Deutsche Bank and BTG. Minister Araújo turned that one down in December 2025.
Why the Venue Fight Is Worth Having
In a Brazilian restructuring the judge sets the pace. The same judge appoints the administrator and decides whether the plan stands.
Creditors who expect one bench to be tougher on a debtor have a reason to fight over the file. Moving it now would restart much of the work.
What Recuperação Judicial Means
Recuperação judicial is Brazil’s court-supervised restructuring. It is close in spirit to Chapter 11 in the United States.
The company keeps trading while it negotiates under the court’s eye. A general meeting of creditors then votes on the plan.
The Meeting That Did Not Happen
The first call, on 25 August 2026, failed for want of a quorum. The second call needed no minimum turnout.
It was set for 1 September at two in the afternoon. That is the meeting the STJ stopped.
The Deadline Ambipar Is Watching
Ambipar sought court protection in late October 2025. It owed about 10.7 billion reais (US$2.1 billion).
Roughly 5.6 billion of that is in dollar bonds and about 3 billion in debentures. Bank loans account for some 2 billion, and suppliers for 230 million reais.
The company has asked Minister Araújo to reconsider. In that filing it says it could fail if the plan is not approved by 18 September 2026.
That is when its court protection expires. Ambipar has made no public statement beyond the filing.
The Shares Have Stopped Trading Normally
Ambipar’s stock, AMBP3, has not traded continuously on B3 since 31 August 2026. The exchange moved it to a call auction that settles only at the close.
The reason is that Ambipar has not filed financial statements since mid-2025. The last price recorded on 1 September was 15 centavos (US$0.03).
The Case
The Brazilian restructuring runs as case 3014764-58.2025.8.19.0001. It sits before the third business court of Rio de Janeiro.
The venue appeals carry their own numbers at the Rio appeal court. The Chapter 11 case runs in parallel in the Southern District of Texas.
