Cosan S.A., the massive Brazilian conglomerate whose operations span energy, infrastructure, and logistics, has filed paperwork with the U.S. Securities and Exchange Commission (SEC) to voluntarily delist its American Depositary Shares (ADSs) from the New York Stock Exchange (NYSE). The last day of trading for the ADSs, which trade under the ticker CSAN, is expected to be September 18, 2026. The move is part of a stated strategy by the company to optimize its capital structure, focus on operations, and reduce the costs associated with maintaining a primary listing on a major U.S. exchange.
