Can Alto Ingredients Sustain Gains as Alcohol Premiums Narrow?
Alto Ingredients (ALTO) reported higher high-quality alcohol volumes (+3.6M gallons YoY) in Q2 2026, but narrower premiums over ethanol reduced revenues by $2.9M. Hedging strategies offset some impact, limiting net premium decline to 2 cents/gallon. Profitability increased modestly despite softer premiums. Shares fell 5.6% in the past month, underperforming peers. Forward P/S ratio is 0.34, below industry average 3.33. Earnings estimates declined 27.8% and 66.3% for 2026 and 2027, respectively.
