3tentos (TTEN3) Stock Plunges 16% as CVM Demands Answers on Alleged Selective Disclosure

Shares of Brazilian agro-retail firm 3tentos (TTEN3) plunged 16.01% on July 28, closing the session at R$12.80, after the company became the subject of an inquiry by the Comissão de Valores Mobiliários (CVM), the country's securities regulator. The significant drop in the B3-listed stock was triggered by reports suggesting the company’s investor relations department shared preliminary Q2 2026 results and revised projections with sell-side analysts, which constitutes a potential breach of market rules on selective disclosure of material information.

The CVM is formally demanding explanations from the company's Investor Relations Director regarding the content and timeline of meetings held with market analysts, which reportedly circulated negative Q2 previews before the close of trading. In response, 3tentos registered a clarification with the CVM on July 29, asserting that all discussions with analysts exclusively used public data pertaining to the Brazilian agribusiness sector. The core regulatory mechanism at risk is the principle of information parity, where selective sharing of non-public, material facts to a few analysts creates an unfair advantage, potentially leading to a formal investigation (processo sancionador) by the CVM.

The market reaction was immediate and sharp, reflecting the elevated regulatory risk for one of the key stocks in the Brazilian agribusiness sector. Analysts cited the possibility of a weaker-than-expected second quarter, specifically pointing to high consumption of working capital and substantial capital expenditure related to the final phase of its corn ethanol plant construction. The broad Ibovespa benchmark, by contrast, saw a modest decline of 1.03%, trading at 174,749.92, while other major B3 stocks traded mixed, with VALE3 falling 0.83% and ITUB4 down 1.98% [live data].

Investors are now focused on the outcome of the regulatory inquiry, with some preparing a formal request for a full CVM investigation into the matter. The most concrete event to watch next will be the CVM’s assessment of 3tentos’s clarification and its subsequent decision on whether to launch a formal punitive process. Furthermore, investors will be monitoring the company's official 2Q26 earnings release, which is scheduled for August 13, 2026.
