Alto Ingredients Applauds Passage of Assembly Bill 30 Expanding E15 Fuel Options in California

PEKIN, Ill., Oct. 06, 2025 (GLOBE NEWSWIRE) -- Alto Ingredients, Inc. (NASDAQ: ALTO), a leading producer and distributor of specialty alcohols, renewable fuels and essential ingredients, welcomes the signing of Assembly Bill 30 by Governor Gavin Newsom, authorizing the sale of E15 fuel, a gasoline blend that contains 15% ethanol, throughout California. This landmark legislation makes it possible for Alto Ingredients and the broader renewable fuels industry to meet the growing demand for more affordable, domestically produced ethanol blends while supporting the state’s clean energy goals.

With E15 fuel sales approved in California, it is now possible to increase ethanol consumption by more than 600 million gallons per year. Alto Ingredients is positioned to leverage its annual ethanol production capacity of up to 350 million gallons to produce low carbon ethanol to supply and support California’s evolving low carbon transportation fuels market.

“We commend Governor Newsom and the California Legislature for expanding consumer choice and paving the way for lower-carbon, cost-effective fuel options like E15,” said Bryon McGregor, Alto Ingredients CEO. “AB 30 validates the critical role of American ethanol and incentivizes companies like Alto Ingredients to invest confidently in infrastructure, create local jobs and help California achieve its ambitious climate objectives.”
