Stonegate Capital Partners has updated its coverage on Aemetis, Inc. (Nasdaq: AMTX), highlighting the company's transition from a capital-intensive buildout phase to a monetizable low-carbon fuels platform. The analysis, based on Aemetis's fourth quarter 2025 results, indicates that the company is beginning to generate meaningful profitability from its renewable natural gas (RNG) business.
According to the report, Aemetis operated 12 dairy digesters during the quarter, producing approximately 405,000 MMBtu of RNG on an annualized basis. Fourth quarter output increased 61% year-over-year, underscoring the scalability of the dairy RNG operations. More importantly, the biogas segment contributed $10.3 million in production tax credits and generated $12.2 million in segment net income, demonstrating that the RNG business is no longer just a future earnings opportunity but an asset already producing significant profitability.
The report notes that Aemetis is positioned to capture value from multiple revenue streams, including RNG molecule sales, D3 RINs, Low Carbon Fuel Standard (LCFS) credits, and federal production tax credits. Seven new California Air Resources Board (CARB) pathway approvals have improved the average carbon intensity of Aemetis's RNG from the negative-150 default to negative-380, enhancing the value of its environmental credits.
Stonegate's analysis sets a median valuation target of $11.7 per share, implying substantial upside from current trading levels. The firm believes that Aemetis is nearing an EBITDA inflection point, as scaling dairy RNG production and improving ethanol economics position the company to transition from a capital-intensive buildout phase to sustained operating cash flow growth.
The integrated platform of dairy RNG, low-carbon ethanol, and sustainable aviation fuel (SAF) optionality enables Aemetis to monetize production through fuel sales, RINs, LCFS credits, and 45Z tax incentives, creating multiple revenue layers. As the company continues to scale its operations, these stacked revenues are expected to drive further profitability.
