Cosan (CSAN3): BofA Sees a Unique and Undervalued Story, Maintains "Buy" with 82% Upside Potential (2025-09-03)

Why Is BofA So Bullish on Cosan (CSAN3)?

Bank of America’s analysts aren’t just throwing around buzzwords—they’ve crunched the numbers. Their "Buy" rating hinges on Cosan’s diversified portfolio, which spans energy, logistics, and mobility. The 82% upside target isn’t just a hopeful guess; it’s based on sum-of-the-parts valuation, which suggests the market isn’t fully pricing in Cosan’s growth potential. "This isn’t your grandpa’s sugar company," quipped one analyst. With stakes in Raízen (a global energy leader) and Rumo (Brazil’s top rail operator), Cosan is a play on Brazil’s infrastructure and energy transition.

Breaking Down the "Unique and Undervalued" Thesis

BofA’s report highlights three key pillars: (1) Raízen’s renewable energy pivot, (2) Rumo’s rail monopoly, and (3) undervalued assets like Compass Gas. Raízen, for instance, is Latin America’s largest sugar/ethanol producer but is now betting big on biogas and solar. Meanwhile, Rumo controls 70% of Brazil’s rail freight—critical for an agricultural powerhouse. "The market’s treating CSAN3 like a commodity stock, but it’s really a hybrid of infrastructure and tech," noted the BTCC research team.

What’s Driving the 82% Upside Potential?

Here’s the math: BofA values Cosan’s Core businesses at R$55/share (vs. current ~R$30). The kicker? That excludes potential M&A or carbon credit windfalls. Raízen alone could add R$10/share if biogas takes off. TradingView charts show CSAN3 has lagged peers like Vibra Energia, but BofA argues this gap closes as renewables gain traction. "It’s a patience play," admits one trader. "But when Raízen’s biogas plants hit scale, this stock could rip."

Risks and Counterarguments

No investment is bulletproof. Critics point to Brazil’s volatile politics and ethanol price swings. A bad cane harvest or regulatory hiccup could dent earnings. Still, BofA’s model builds in a 15% "Brazil risk discount." Their retort? "Even with haircuts, this is cheap." The BTCC team adds that Cosan’s liquidity (avg. daily volume: R$200M) makes it a safer play than smaller Brazilian stocks.

How Does Cosan Stack Up Against Other Brazilian Giants?

Compared to Petrobras or Vale, Cosan offers something different—a hedge against both commodity cycles and decarbonization. Its EV/EBITDA of 4.5x trails Petrobras’ 6x, per TradingView data. "You’re paying for optionality," says an asset manager. "If Rumo wins new rail concessions or Raízen cracks green hydrogen, multiples expand fast."
