Stonegate Capital Partners has updated its coverage on Aemetis, Inc. (Nasdaq: AMTX), emphasizing that the company is shifting from a capital-intensive buildout phase to a monetizable low-carbon fuels platform. The Q4 2025 results provide strong evidence of this transition, particularly through the performance of its Dairy Renewable Natural Gas (RNG) segment.
Aemetis now operates 12 dairy digesters, producing approximately 405,000 MMBtu of RNG annually. Fourth-quarter output increased 61% year-over-year, demonstrating operational scaling. More importantly, the Biogas segment generated $10.3 million in production tax credits and $12.2 million in segment net income during the quarter, confirming that the RNG business is already producing meaningful profitability rather than being a future opportunity.
The earnings base from RNG is expected to grow as Aemetis captures value from multiple revenue streams: RNG molecule sales, D3 RINs, Low Carbon Fuel Standard (LCFS) credits, and federal production tax credits. The company recently received seven new California Air Resources Board (CARB) pathway approvals, improving the average carbon intensity of its RNG from the default negative-150 to negative-380, which enhances credit generation.
Stonegate's analysis sets a median valuation target of $11.7 per share, implying substantial upside from current trading levels. The firm notes that Aemetis is nearing an EBITDA inflection point as scaling Dairy RNG production and improving ethanol economics position the company for sustained operating cash flow growth.
The integrated platform—combining 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. This stacked revenue approach is expected to drive the company's financial performance as it continues to scale operations.
