AI Analysis
AI-generated, general educational analysis — not personal investment advice.
I start with the numbers. At $3.01 on 2026-10-02, Cosan has a $4.0B market cap. In the latest filed quarter, fiscal Q2 2026, revenue was $10.8B and net income was -$320.5M, a -2.97% margin. That is not a healthy earnings picture. The FairStock-calculated P/E is -1.34, P/B is 3.07, ROE is -27.22%, ROCE is 5.56%, and D/E is 1.91. The Altman Z-Score of 0.18 signals balance-sheet stress. Mr. Market is not paying much for the equity: the 52-week range is $2.38-$5.61, and beta is 0.48. But cheapness alone is not enough. The TTM free cash flow of $4.6B, a 115.9% FCF yield per FairStock, is extraordinary; either the market disbelieves its durability or the number is distorted by working capital, asset sales, or cyclical timing. Piotroski 6/9 and EV/EBITDA 9.36 suggest some operating merit. The provided revenue growth figure is 2.85%, though the period is not specified. The computed Lynch category is none because there are only 0 years of filed results, needing 3. Cosan is a diversified energy and logistics complex: fuel distribution, sugar/ethanol, natural gas, lubricants, rail. As a Graham-style investor, I want a margin of safety in assets and earnings. Here the asset multiple is not low, earnings are negative, leverage is high, and the cash-flow yield is the main attraction. That is speculative value, not comfortable value. A 47/100 FairStock Score captures the mixed picture.
In plain English: The company sells fuel and makes sugar, ethanol, and natural gas, with logistics and other businesses. It is losing money and carries a lot of debt, and the latest quarter showed a net loss. The shares look cheap compared with the cash the business generated over the past year, but that cash may not be dependable while profits are negative.
