São Martinho’s stock (SMTO3) surged 15% in early trading today following a blockbuster earnings report and a bold announcement to double its corn ethanol production by 2026. The Brazilian sugar-and-energy giant posted a 42% YoY profit jump, crushing analyst expectations. Meanwhile, its pivot toward corn-based biofuels—a sector growing at 30% annually—has investors buzzing. Here’s why the market is betting big on this 75-year-old agro-industrial titan. ---
Why Did São Martinho’s Stock Explode Today?
The answer lies in two back-to-back bullish catalysts. First, Q2 2025 earnings revealed R$1.2 billion in net income (up from R$845 million YoY), driven by record sugar prices and cost-cutting measures. Second, CEO Walter Mello announced a R$800 million investment to expand corn ethanol capacity at its Nova Fronteira plant—a MOVE that could make SMTO3 Brazil’s second-largest producer. "This isn’t just about ethanol; it’s about future-proofing our energy division," Mello told analysts during the earnings call.
How Significant Is the Corn Ethanol Play?
Game-changing, according to BTCC’s commodities team. While sugarcane ethanol still dominates Brazil (85% market share), corn-based output grew 210% from 2020–2024. São Martinho’s expansion taps into three trends: (1) rising corn surpluses due to record harvests, (2) cheaper storage vs. sugarcane, and (3) growing demand from the aviation sector (SAF mandates kick in 2026). The company expects corn ethanol margins to hit 28%—5 percentage points higher than sugarcane.
What Do the Financials Reveal?
A textbook case of operational leverage. Despite a 9% revenue dip (R$4.3 billion vs. R$4.7 billion YoY), EBITDA margins expanded to 34% from 26% last year. TradingView data shows SMTO3’s free cash Flow yield now leads peers at 8.4%. "They’ve turned into a cash machine," remarked Credit Suisse’s Maria Fernandez, who upgraded the stock to "Outperform."
Risks to Consider?
Three stand out: (1) Corn price volatility (futures suggest a 12% upside), (2) potential sugar-ethanol policy shifts under Brazil’s new energy minister, and (3) execution risks—the Nova Fronteira expansion requires 18 months of construction. That said, with 63% of analysts now rating SMTO3 a buy (up from 47% in Q1), the Street clearly sees more upside.
Historical Context: Why This Move Matters
Founded in 1950, São Martinho built its empire on sugarcane. Its 2018 foray into corn ethanol was initially seen as experimental. Fast-forward to today: the division contributes 19% of profits. The latest expansion mirrors strategies by rivals like Raízen (RAIZ4), but with a twist—SMTO3’s plants are 100% self-sufficient in biomass energy, a cost advantage worth R$120/ton.
What’s Next for Investors?
All eyes are on the September 12 shareholder vote to approve the capital expenditure. If passed, SMTO3 could gain first-mover advantage in central Brazil’s corn belt. "They’re playing chess while others play checkers," quipped a BTCC analyst, noting the company’s 12-year tax incentives in Goiás state. Short-term, options markets imply a 70% chance the stock hits R$55 by October—a 22% gain from current levels.
FAQs
How much corn ethanol does São Martinho currently produce?
1.2 billion liters annually—about 11% of Brazil’s total corn ethanol output.
What’s the dividend outlook?
Q2’s R$0.98/share payout suggests a 4.3% forward yield, though management hinted at potential special dividends if corn ethanol margins hold.
Is this growth sustainable?
With Brazil’s ethanol demand projected to grow 6% annually through 2030 and SMTO3’s cost advantages, most analysts say yes.
