Cosan S.A. plans a major primary equity raise through two Brazilian public share offerings to cut debt and reduce leverage. The first offering is expected to issue 1,450,000,000 common shares, with a potential 25% additional lot, and is anchored by investors associated with BTG Pactual and Perfin Infra who have committed to invest R$ 7,250,000,000 at R$ 5.00 per share. A second primary offering is expected to issue up to 550,000,000 additional shares with priority rights for existing shareholders as of September 19, 2025, at the same price per share.
In total, the offerings will not exceed 2,000,000,000 new common shares. A new holding company will aggregate the anchor investors’ stake, and a shareholders’ agreement among the controlling family vehicles, the new holding and investors will be signed. Significant portions of the new shares will be subject to lock-up periods of 100 days, two years or four years, depending on the holder. The transaction requires shareholder approval to increase authorized capital to up to 8,000,000,000 shares and a waiver from a mandatory tender offer, and the first offering must be settled by November 14, 2025.
COSAN S.A. uses this report to clarify recent press coverage about potential transactions. The Company explains that, as it has stated on prior quarterly earnings calls, it is continuously evaluating alternatives to improve its capital structure. Together with its partner Shell, Cosan is seeking new investors for Rafzen, and has been actively approached by parties interested in potential investments in both companies.
Cosan stresses that discussions with interested parties are still ongoing and that no decision or binding commitment has been made so far. The Company states it will keep shareholders and the market informed of any material developments related to these evaluations, in line with applicable legislation.
