Aemetis Biogas LLC

Aemetis Biogas LLC operates as a key subsidiary of Aemetis, Inc. (NASDAQ: AMTX), a renewable natural gas and renewable fuels company. It specializes in producing renewable natural gas (RNG) by installing and managing anaerobic digesters on dairy farms throughout California's Central Valley. These facilities capture methane emissions from cow manure, which would otherwise contribute to greenhouse gases, and upgrade the biogas into pipeline-quality RNG for use as a transportation fuel.

The company's infrastructure includes a network of dairy digesters, extensive biogas pipelines spanning dozens of miles, and a central processing facility connected to the utility gas grid. As of mid-2026, it has expanded to over a dozen operating digesters, with plans and contracts for many more dairies to reach full capacity of over 1.6 million MMBtu of RNG per year. This supports significant reductions in carbon emissions, equivalent to removing hundreds of thousands of vehicles from roads over time.

Revenues are derived from RNG sales, California Low Carbon Fuel Standard credits, federal Renewable Fuel Standard RINs, and transferable Inflation Reduction Act tax credits. Financing includes USDA-guaranteed loans and equity from the parent. Aemetis Biogas LLC is headquartered in Cupertino, California, and its operations are consolidated into Aemetis' financial reporting. It plays a vital role in Aemetis' strategy to deliver negative carbon intensity products and advance the circular bioeconomy in agriculture and energy sectors.
