BRAZIL · COMPANY NEWS
A São Paulo court has suspended a shareholder meeting at Oncoclínicas do Brasil, a Brazilian private cancer-treatment chain. The meeting was due on Friday 6 November 2026, and no new date has been announced.
The chain has been restructuring its debts and is in a dispute with a shareholder over a mandatory offer. Its shares trade on B3, the São Paulo stock exchange, as ONCO3.
Key Facts

- Next step No new meeting date has been announced.
- Board One director resigned on Wednesday 30 September 2026, and the company says the whole board must be re-elected.
- Offer fight On Friday 23 October a federal court suspended, for now, the duty of Josephina III to launch a mandatory buyout offer.

What the Court Decided
The 3rd Business and Arbitration Conflicts Court of São Paulo suspended the shareholders’ meeting set for Friday 6 November 2026. The fund Josephina III had asked for it.
The same order suspended the effects of the notices that convened the meeting. Those notices are the formal calls telling shareholders when and where to vote.
Oncoclínicas filed a notice to the market, a formal announcement to investors, saying it suspended the meeting because of the court decision. Oncoclínicas runs cancer-treatment clinics across Brazil.
A Resignation Reopens the Whole Board
Board member Paulo Roberto Belem Junior tendered his resignation on Wednesday 30 September 2026. The company says the whole board must now be re-elected.
The board was elected by cumulative voting, a system that lets minority holders pool their votes to win seats. Under it, one resignation means shareholders must renew the whole board at the first meeting.
The company has not yet said when a new meeting will be held. The order itself sets no new date.
The Fight Over the Buyout Offer
A second dispute sits behind the board fight. The company’s own bylaws (its founding rules) contain a tender-offer duty, a mandatory offer to buy out minority shareholders if a holder crosses a threshold.
On Tuesday 25 August 2026 the Comissão de Valores Mobiliários (CVM), Brazil’s market watchdog, concluded that the duty had been triggered. On Friday 23 October 2026 a federal court in São Paulo provisionally suspended the duty of Josephina III to launch the offer.
The dispute over the offer has gone to arbitration. Its outcome is still open.
In Plain English
Josephina III is a fund tied to Centaurus Capital, and it is the shareholder in the middle of both fights. Cumulative voting protects smaller holders, which is why one resignation reopens every board seat.
What It Means for You
