S&P cuts Cosan rating to B+ on weaker diversification By Investing.com
S&P Global Ratings downgraded Cosan S.A. (NYSE:CSAN) issuer credit rating to B+ from BB- and removed it from CreditWatch with negative implications. It also cut Cosan Overseas Ltd. perpetual notes to B+. S&P cited weaker diversification after Raízen’s 65 billion real debt restructuring, expecting interest coverage below 1.0x and leverage around 2.5x-3.0x in 2026.
How this was made
The 30-second read
Why it matters
The downgrade is driven by uncertainty around Cosan’s divestment strategy and the impact of Raízen’s debt restructuring, which dilutes Cosan’s investment and reduces expected dividend inflows and debt service coverage.
Market read
Credit metrics and rating actions can quickly reprice CSAN’s perceived default/refinancing risk, especially given S&P’s expectation of interest coverage below 1.0x without further asset sales.
What to watch
The article emphasizes coverage below 1.0x absent asset sales, but does not quantify timing or probability of future sales, which could materially change the credit trajectory.
Background
S&P placed Cosan on CreditWatch with negative implications in March 2026, then downgraded the issuer and perpetual note issue ratings on July 8, 2026.
Ticker impact
S&P cut Cosan’s issuer credit rating to B+ from BB- and removed it from CreditWatch with negative implications.
Near-term downside bias for CSAN as credit quality deteriorates and debt service coverage is expected to stay below 1.0x without further asset sales.
The article cites specific rating actions (issuer and perpetual notes), a negative outlook rationale, and quantified coverage/leverage expectations over 2026-2027.
Market effects
Credit downgrades for commodity-linked holding companies can raise perceived refinancing and dividend sustainability risk across similar structures.
Brazil-linked cash upstream and leverage metrics may weigh on local credit sentiment, especially for conglomerates exposed to restructuring outcomes.
International rating actions can affect cross-border bond pricing and investor risk premia for issuers with overseas subsidiaries.
Counterpoint
If Cosan executes additional divestments that simplify the capital structure, the negative outlook could stabilize faster than the base-case coverage assumptions imply.
