Cosan S.A. has formally notified the New York Stock Exchange that it intends to voluntarily delist its American Depositary Shares, according to a material fact announcement published by GlobeNewswire Energy. The ADSs are represented by American Depositary Receipts, each covering four common shares of Cosan with no par value.
The move follows a resolution adopted by Cosan's Board of Directors on August 14, 2026. The notification to the NYSE covers the ADS line only.
Cosan said the transaction forms part of its objective to simplify and optimize its capital structure, with cost reductions and a greater focus on its most strategically relevant business areas.
The company will keep its common shares listed on the Novo Mercado segment of B3 S.A. - Brasil, Bolsa, Balcao in Brazil, where trading in the shares is predominantly concentrated, according to the announcement. Novo Mercado is B3's segment carrying the most demanding corporate governance requirements for listed issuers.
Delisting from the NYSE does not end Cosan's US disclosure duties. The company said it will remain registered under the U.S. Securities Exchange Act of 1934 and will continue complying with its reporting obligations under that statute after the NYSE delisting takes effect.
The combination of an exchange exit with continued Exchange Act registration is the narrower of two available routes for a foreign private issuer: it strips out the listing fees and exchange-level compliance load of a dual venue while leaving periodic reporting to US investors intact. Cosan framed the decision in terms of capital structure and cost, not disclosure appetite.
The stated concentration of trading on B3 is the operative commercial fact. An ADS line that carries a small share of total volume generates listing and depositary costs disproportionate to the liquidity it provides, and consolidating price formation on the home market removes that duplication.
