HSBC slashed its price target and outlook mainly due to two core problems, including rising financial expenses, which are impacting the company’s bottom line, and asset sales being executed at unfavorably low prices. The firm noted the restructuring that was carried out in October 2025 to be too little, too late. HSBC notes that Cosan S.A. (NYSE:CSAN) moves have not been enough to offset the damage from a prolonged high-interest-rate environment, which has made its debt burden increasingly costly to manage.

​In separate news, the company reported its fiscal Q1 2026 earnings on May 14. Cosan S.A. (NYSE:CSAN) posted a net loss of R$1.6 billion, reflecting a modest R$0.2 billion improvement year-over-year. The result was heavily impacted by R$1.0 billion in costs tied to early repayment of its 2029, 2030, and 2031 bonds. This was seen as a deliberate but expensive move to clean up its debt structure.

​On the debt side, expanded net debt rose 18% quarter-over-quarter to R$11.5 billion, driven by the absence of dividend inflows and one-off prepayment costs. However, compared to Q1 2025, net debt decreased 34%, mainly due to a capital raise completed late last year.
