Cosan S.A. filings document foreign-private-issuer reporting for an ADR issuer with investments across energy, logistics, gas, lubricants and related infrastructure. The company’s Form 6-K reports and Form 20-F annual reporting cover IFRS financial statements, management reports, operating results and portfolio disclosures for businesses including Raízen, Compass, Moove and Rumo.

These disclosures connect Brazilian CVM material facts with U.S. reporting for Cosan’s NYSE-listed American depositary shares.

Cosan S.A. executive Rafael Bergman, Chief Finance Officer, filed an initial ownership report showing his equity position in the company. He reports direct ownership of 232,662 shares of common stock (BVMF: CSAN3) and 55,242 units tied to a long term incentive based on the same stock.
Cosan S.A. reports that its affiliate Raízen S.A. and certain subsidiaries have filed for an out-of-court reorganization in Brazil to restructure unsecured financial indebtedness of approximately R$65.1 billion and related intercompany claims. The process has been consensually structured with main unsecured financial creditors, and more than 47% of this indebtedness is already supported by consenting creditors, enough to initiate the proceeding. The reorganization is described as strictly financial and does not affect Raízen’s obligations to customers, suppliers, distributors or other key partners, which will continue in the ordinary course. Cosan states that this process does not involve or affect Cosan’s own obligations, operations, capital structure or financial position, and that the Cosan Group’s activities and commercial relationships remain unchanged, with no direct impact from Raízen’s filing.
COSAN S.A. reported a net loss of R$5.8 billion in 4Q25 and R$9.7 billion for 2025, driven mainly by large non-recurring, non-cash impairments at Raízen linked to going concern uncertainties and capital structure imbalance.
Corporate expanded net debt fell sharply to R$9.8 billion from R$23.5 billion, helped by a R$10.5 billion follow-on offering, R$2.8 billion raised via a Total Return Swap on Rumo shares, and multiple bond redemptions and tenders. Cash and cash equivalents at the corporate level reached R$16.0 billion, and the average debt cost declined to CDI + 0.97% per year.
At the group level, adjusted EBITDA under management was R$7.8 billion in 4Q25 and R$26.5 billion in 2025, down year over year mainly due to weaker Raízen results. Pro forma leverage ended 2025 at 3.3x adjusted EBITDA, while Cosan Corporate’s debt service coverage ratio over the last twelve months was 0.9x, reflecting lower dividend inflows from portfolio companies.
Cosan S.A. reported 2025 consolidated net sales of R$40.4 billion, down 8% from 2024, and a consolidated net loss of R$10.2 billion. Loss attributable to Cosan’s shareholders was R$9.7 billion, similar to 2024, mainly reflecting a R$10.9 billion equity-method loss on joint venture Raízen and other investee impacts, partially offset by higher other operating income.
Raízen recorded high indebtedness, significant losses and negative equity of R$1.13 billion, leading its own management to disclose significant uncertainty about its ability to continue as a going concern. Cosan reduced the Raízen investment to zero and, after legal review, did not record further obligations.
Cosan executed a major recapitalization, raising R$10.27 billion in two primary share offerings at R$5.00 per share, strengthening capital and liquidity. It also reported early redemptions and tender offers on bonds and debentures, with total debt prepayments of about R$6.2 billion, alongside new long-term debenture and bank funding across Cosan Corporate, Compass, Rumo and Moove.
Moove’s Rio de Janeiro lubricants complex suffered a fire affecting about 10% of the site, driving asset and inventory write-offs, but insurance recoveries of R$933.7 million fully covered recognized operational losses. Agricultural investment properties reached a fair value of R$18.22 billion, generating a R$1.44 billion fair value gain. Auditor PwC issued an unmodified opinion on the 2025 parent and consolidated IFRS financial statements and highlighted Raízen obligations, Compass gas concession assets, and investment property fair value as key audit matters.
Cosan S.A. plans a secondary public offering of common shares in its controlled company Compass Gás e Energia S.A. in Brazil, with placement efforts also targeting investors abroad. The deal is a resale of existing Compass shares, not a new share issuance.
On the same date, Compass requested migration of its listing on B3 to the Novo Mercado segment, which emphasizes stronger corporate governance. The offering depends on registration by the Brazilian securities regulator, approval of the migration by B3, necessary corporate approvals, and prevailing market conditions. The shares will only be registered in Brazil and are not registered under U.S. securities laws.
Cosan S.A. has disclosed that it is evaluating a potential initial public offering of shares issued by its subsidiary Compass Gás e Energia S.A., referred to as the “Potential Offering.” This is an exploratory step and not a final decision to proceed.
The company states that any effective offering would depend on domestic and international market conditions and the receipt of required corporate approvals. Cosan emphasizes that, as of the announcement date, no decision has been made regarding completing the offering and it will inform the market of further developments.
Cosan S.A. reports that its wholly owned subsidiary, Cosan Luxembourg S.A., is fully redeeming its senior notes due June 2030 and January 2031. The principal amount of the 2030 bond is US$269,334,000.00, and the 2031 bond totals US$300,000,000.00.
This step is part of a liability management process stemming from public offerings carried out in 2025, aimed at reducing indebtedness and financial costs and improving the capital structure. With this redemption, Cosan states it has repaid approximately R$6.2 billion of debt to date.
