A stock that rose 883 percent, three funds connected to a bank now in liquidation, and a company that has since filed for judicial recovery.
Brazil’s securities regulator is investigating funds tied to Banco Master over their purchases of Ambipar shares during a period in which the stock rose 883 percent.
What the CVM Is Looking At
The funds named in the reporting are Esna, Texas and Kyra, all linked to the Master group. Between June and August 2024 they bought roughly R$754 million (about US$148 million) of Ambipar stock.
Over the relevant period the shares rose 883 percent. The reporting describes the controller, Nelson Tanure, as the beneficiary of that move.
A regulator examining whether fund purchases drove a price rise that benefited a connected party is standard market-abuse territory. What makes it unusual here is the identity of the funds and the state of the bank behind them.
What Ambipar Is
Ambipar is an environmental and emergency-response services group listed on the B3 as AMBP3, with operations across waste management, industrial services and emergency response.
It is currently in recuperação judicial over R$10.48 billion (about US$2.06 billion) of debt. Creditors approved a plan and a further assembly was scheduled after an earlier one failed to reach quorum.
That restructuring is a distinct process from the CVM investigation, and the two should not be described as one story. What connects them is that the same shareholder register sits underneath both.
A Claim That Does Not Hold
Reports circulating on Saturday said Justice André Mendonça had postponed a CVM deposition in which Daniel Vorcaro was to answer questions about Ambipar and other investment funds.
The Rio Times could not confirm that. No such deposition or postponement appears in the available reporting.
What is documented is different. Vorcaro has federal police depositions, not CVM ones: one concerning the alleged hiring of influencers to attack the central bank, which was postponed without a new date, and one on BRB-related card fraud set for 15 September.
The distinction matters for anyone holding AMBP3. A regulator investigating funds that bought the stock is a real and checkable fact. A postponed deposition about the company is not established.
Why an 883 Percent Move Attracts a Regulator
Price moves of that size in a listed company are not in themselves evidence of anything. Small and mid-cap Brazilian stocks can run hard on genuine news, and Ambipar had a real growth story attached to environmental services and emergency response.
What draws a regulator is the combination. A concentrated set of buyers, a connected relationship between those buyers and a beneficiary of the move, and a compressed timeframe are the three elements that turn a rally into a market-abuse question.
The CVM has all three here on the reporting: three named funds, a stated beneficiary in the controller, and a window of roughly three months in mid-2024.
None of that is a finding. An investigation establishes whether the pattern has an innocent explanation, and a great many do.
What Happened to the Company Afterwards
Ambipar went into judicial recovery with R$10.48 billion (about US$2.06 billion) of debt, a restructuring large enough to put it among the more significant Brazilian corporate insolvencies of the cycle.
Creditors approved a plan and a further assembly was called after an earlier one failed to reach quorum, which is a routine procedural step rather than a sign of collapse.
For a shareholder, the two processes point in different directions. The restructuring determines whether the equity retains value. The CVM investigation determines whether the price at which some parties bought it in 2024 was fairly arrived at.
Neither answers the other, and the company’s operating business continues through both.
