On September 30, 2026, UBS Lumen asked Oncoclinicas to call a shareholder meeting to replace the board, according to Valor Economico. The proposal names seven candidates and gives Oncoclinicas stock a governance catalyst while the company works through a BRL 5.1 billion debt restructuring.

Seven seats and 4.93 percent stake

UBS Lumen delivered the request on September 24, 2026, and holds 55,966,951 ordinary shares, equal to 4.93 percent of the company in circulation, according to Valor Economico. The fund wants the current directors removed, the board fixed at seven members and a new election held.

The request has not yet become a board decision. Valor Economico reported on September 30, 2026, that the company was reviewing the proposal and had up to eight days to respond, keeping the governance question open for shareholders.

Debt shapes the board debate

The governance dispute arrives during a financial restructuring. Rio Times reported on September 27, 2026, that Oncoclinicas began a court-backed restructuring in July covering BRL 5.1 billion of debt.

The operating figures underline the pressure. Renova Invest reported that a quarterly loss reached BRL 275.3 million in the results released in August 2026, four times the comparable loss, while procedures fell 32.60 percent to 114,000.

B3 value stays in a wide range

On B3, Oncoclinicas traded at BRL 1.01 on October 2, 2026. Its market capitalization was BRL 1.1 billion, while the 52-week range extended from BRL 0.53 to BRL 3.91, placing the quote closer to the lower end than the upper end of that interval.

The latest corporate action therefore carries two measurable dimensions: a 4.93 percent shareholder seeking seven board seats and a BRL 5.1 billion restructuring. For Oncoclinicas stock, governance decisions and debt execution are now closely linked in the company narrative.
