Alto Ingredients has surged 343.6% over the past year yet still trades at a forward price-to-sales ratio of 0.4, well below the industry average of 3.29 and the sector average of 2.28. The company swung to a first-quarter 2026 profit of 5 cents per share from a year-ago loss of 16 cents, with adjusted EBITDA improving to $4.7 million from negative $4.4 million. Favorable industry dynamics, including strong export demand and higher corn oil prices, helped lift board crush margins to 17 cents per gallon from 2 cents a year earlier. Alto also recognized $3.9 million in Section 45Z tax-credit earnings in the quarter and expects roughly $15 million in annual net proceeds from qualifying production. Despite the strong rally, the stock remains attractively valued compared with peers such as Green Plains, Gevo, and MGP Ingredients, though commodity price volatility and potential industry margin compression pose risks.
