Rhea-AI Summary

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.

Rhea-AI Summary

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.

Rhea-AI Summary

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.

Rhea-AI Summary

Cosan S.A. reports that Banco Bradesco BBI S.A. and Banco BTG Pactual S.A. have jointly acquired preferred shares of Cosan Dez Participações S.A. for a total of R$4 billion. These shares represent approximately 23% of Cosan Dez’s total share capital and grant political rights equivalent to 9.98% of its voting capital.

Cosan Dez holds the shares of Compass Gás e Energia S.A. owned by Cosan. The transaction renegotiates financial terms previously agreed with Bradesco BBI in 2022. As part of the new structure, Cosan granted Bradesco BBI and BTG Pactual a put option on their Cosan Dez shares, exercisable in one or more stages from the 5th, 6th and 7th anniversaries of the transaction. Cosan states that this reduces the financial cost of the prior arrangement and aligns with its strategy to optimize liabilities following a recent capitalization.
